Ryzen 3000 CPUs were a milestone for AMD. With the introduction of the latest 8-core Ryzen 4000 mobile processors from AMD, the company is intensifying its competition with the desktop and laptop silicon from Intel. AMD's goal is to bring out laptops that are as powerful as they are thin with the Ryzen 4000 processors of the U-series, as well as performance-oriented notebooks with more powerful Ryzen 9 4900H and Ryzen 9 4900HS chips.

As in previous generations of AMD Ryzen processors, the 4000 series will consist of the latest generation of mobile architecture processors and new generation architecture desktop chips, with market launches being split between the early and later parts of the year.

Here you will find everything we know about AMD Ryzen 4000 CPUs.

Prices and release date

At CES 2020, AMD presented the first Ryzen 4000 CPUs, on which a new generation of mobile accelerated processor units (APUs) was presented. These are Zen 2 CPU cores (included in Ryzen 3000 desktop CPUs) paired with Vega graphics cores.

A full range of chips have been announced, from low-end to high. Various manufacturers will be offering these in laptops in the coming months. Two of the first models mentioned are Lenovo Yoga Slim 7 and Asus Zephyrus G14. Since then, a number of Ryzen 4000 laptops have been launched.

Mobile gamers are drawn to AMD's flagship Ryzen 4000 mobile processors, including the Ryzen 9 4900H and 4900HS CPUs. Both chips are designed in such a way that they can accommodate the Intel Core i9 silicon in the high-end area for mobile games. Laptops with AMD's Ryzen 9 4900H and 4900HS were launched in the spring and will be released all year round

After contesting that the Ryzen 4000 desktop processors were delayed, AMD announced in late July its Ryzen 4000 desktop APU, which is based on the company's Zen 2 core. The new Ryzen 4000 desktop processors will be available in both consumer and commercial Pro brand variants. At first, however, these chips can only be found in pre-made desktops, much to the horror of players who want to update existing rigs.

Like its mobile counterpart, the Ryzen 4000 desktop processors will also feature built-in Radeon graphics that allow casual gamers to play 1080p titles without a dedicated and expensive graphics card. These desktop chips are essentially mobile Ryzen 4000 processors that can be optimized for better performance thanks to larger heat budgets in a desktop case.

AMD is also planning a second version of its Ryzen 4000 desktop processor based on the Zen 3 cores, but the company has not announced the timing for this launch.

Since players cannot buy the Ryzen 4000 desktop chips à la carte, we have no pricing information. However, we would expect a similar surcharge to the current Ryzen 3000 series, with CPUs priced from $ 100 APUs up to around $ 750 for the most powerful multithreaded CPUs.

Architecture

Ryzen 4000 series CPUs, like Ryzen 3000 before, use a combination of two architectures throughout the range. The new mobile Ryzen 4000 CPUs will use the existing Zen 2 architecture as well as the Ryzen 3000 desktop CPUs, but in a different way. While the latter used a chiplet design in which CPU cores were split into miniature chips and paired with a larger I / O chip, the Ryzen 4000 Zen 2 mobile CPUs are manufactured using a more traditional monolithic single chip.

AMD claimed that the benefits of chiplet design were far less noticeable on a laptop CPU, and decided to incorporate more elements – such as LPDDR4X and low-power audio – into the monolithic chip design.

This should mean higher energy efficiency because the I / O chip is absent and needs its own energy. However, the cache is reduced and there is the possibility of additional memory latency due to decoupling the infinity structure from system memory.

AMD Ryzen 4000 series

However, Zen 2 on Ryzen 4000 mobile chips will continue to be a significant upgrade over existing Ryzen 3000 mobile APUs based on the Zen + design. It reduces the size of the process node from 12 nm to 7 nm and has a number of improvements in architectural efficiency. Similar to Zen 2 desktop chips, the first Ryzen 4000 laptops offer higher instructions per clock of 15% and higher base and boost clock frequencies.

The eight mobile cores are divided into two CCX units, with the L3 memory reduced from 8 MB on the desktop design to 4 MB per CCX. Thanks to a 7 nm design, AMD can reduce power consumption in active and idle modes. Latency has also been reduced, so laptops benefit from faster startup times, faster applications, and longer battery life.

In early test results released by AMD, the Ryzen chip of a Lenovo Yoga Slim 7 outperformed a comparable Intel Core i7-1065G7 system in terms of web browsing and graphics activity, while the battery life was comparable. In idle time, however, the AMD system still loses 7.5 hours compared to the connected Intel standby mode.

AMD may be working on optimizations for improved battery performance. A leak from an unannounced – and possibly deferred – Lenovo Legion 5 gaming laptop released by Notebook Check suggests that the AMD variant doubles the battery life of a comparable Legion 5 configuration with an Intel Comet Lake H-CPU could have. Leaked MobileMark 2018 battery tests from Lenovo have shown that the AMD version can achieve a battery life of up to 13.5 hours, compared to 7.7 hours for the Intel version. If these benchmarks are correct, this will be of great benefit to gamers on the go and creatives who need to use a mobile workstation while not in an electrical outlet.

AMD's performance-oriented mobile Ryzen 9 4900HS is a 16-thread processor with eight cores, a base clock speed of 3.0 GHz and a boost speed of 4.3 GHz. The chip only consumes 35 W TDP. The 4900H processor consumes slightly more power at 45 watts TDP, but enables a faster base speed of 3.3 GHz and a boost speed of 4.4 GHz.

No official third-party benchmarks have been released so far, but AMD's internal testing suggests that its silicon will be very competitive with Intel's high-end cellular offerings. AMD's mobile processor also uses the company's SmartShift technology to enable laptops to intelligently optimize performance between the CPU and GPU for better gaming performance.

performance

The mobile Ryzen 4000 CPUs should have a significant increase in performance compared to their Ryzen 3000 counterparts. We have seen that switching to 7nm Zen 2 delivers cross-generational improvements between 15% and 20% for single-thread tasks and 25 to 30% in multithreaded scenarios. This was most notable in games where the enlarged cache helped increase the frame rate by 20% to 30% per second and significantly improved the lowest frame rates of 1% and 0.1%.

Compared to Intel's mobile architecture, AMD stated that the Ryzen 4000 mobile chip delivers twice as good performance per watt. That meant much greater consistency and frame rate stability.

Cores / threads base Boost graphic TDP
AMD Ryzen 7 4800H 8/16 2.9 GHz Up to 4.2 GHz 7 Radeon cores 45W
AMD Ryzen 7 4800U 8/16 1.8 GHz Up to 4.2 GHz 8 Radeon cores 15W
AMD Ryzen 7 4700U 8/8 2.0 GHz Up to 4.1 GHz 7 Radeon cores 15W
AMD Ryzen 5 4600 U. 6/12 2.1 GHz Up to 4.0 GHz 7 Radeon cores 15W
AMD Ryzen 5 4600H 6/12 3.0 GHz Up to 4.0 GHz 6 Radeon cores 45W
AMD Ryzen 5 4500U 6/6 2.3 GHz Up to 4.0 GHz 6 Radeon cores 15W
AMD Ryzen 3 4300U 4/4 2.7 GHz Up to 3.7 GHz 5 Radeon cores 15W
AMD Ryzen 3 3250U 2/4 2.6 GHz Up to 3.5 GHz 3 Radeon cores 15W

This will likely also be the case with Ryzen 4000 Zen 2 chips, which are supported by AMD's traditionally strong onboard graphics. The Vega graphics architecture may be a few years old – based on the outdated GCN architecture rather than AMD's newer Navi designs – but improvements to the 7nm process node have reportedly outperformed its last generation counterparts by almost 60 % elevated.

With its multithreaded performance, the eight-core, 16-thread Ryzen design gives content creators serious power over quad-core laptops. In a coding test, the video was encoded 40% faster on the Ryzen 4000 than on the Quad-Core Core i7-10510U from Intel. Thanks to the strong multithreaded performance, Ryzen laptops are powerful mobile workstations. AMD joins Intel's lead with single-core performance. The AMD test with the Cinebench R20 tool showed a 25% improvement in single core performance over the previous generation while still using 15W thermal design power.

The eight-core Ryzen architecture delivered 77% more maximum memory bandwidth for a total throughput of 1.79 TFLOPS. As a result, the graphics clock speeds were increased to 1,750 MHz. Together, they should make Ryzen 4000 APUs ideal for entry-level gaming laptops. They will compete against the new Intel Ice Lake and the upcoming mobile Tiger Lake processors with their more powerful integrated Gen 11 graphics. When gaming on Fortnite, AMD claimed that its graphics were 21% ahead of Intel in its tests. AMD's lead on Grand Theft Auto V is up to 45%, but titles like League of Legends and Counter-Strike: Global Offensive performed better.

According to the AMD's internal tests, the 4900HS outperformed the Intel Core i9-9880H in the Cinebench R20 benchmark by more than 25%. Similarly, the AMD processor outperformed its Intel competitor by 23% in video transcoding, 32% in audio coding, and more than 55% in image rendering. The company admitted that the Intel i9 outperformed a PCMark 10 benchmark by up to 8%.

The AMD metrics were largely confirmed by Techspot's tests of the Ryzen 7 4800H processor, which clearly outperformed the Intel Core i9-9880H in both the Cinebench R20 and R15 CPU coding benchmarks, as well as Handbrake's video coding tests. When decompressing zip files, the publication also found that AMD's silicon offers a 32 percent advantage over the Intel Core i7-10875H. AMD's laptop processor can hold its own against Intel in important office tasks, but Intel's newer mobile mainstream processors prevail over Ryzen in multimedia workflows.

Despite better graphics, you're still limited to 1080p games – avid gamers will still need their own GPU – and you'll need to tweak your game settings to get the game performance you want. When AMD's mobile processor is paired with Nvidia's GeForce RTX 2060 graphics card in a sleek Max-Q gaming laptop design, the company says the overall performance for a number of high-end titles can be 60 frames per second exceed. According to AMD, Rise of Tomb Raider's performance was 104 FPS and Far Cry 5 and Hitman's 90 FPS. The Ryzen-RTX pairing delivered almost 230 FPS for esports titles like Rocket League and CS: Go.

In addition to the Ryzen 9 4900H and HS series, AMD's mobile offering also includes the U series for ultra-flat laptops that can still be used for casual games. Given that thin and light laptops weren't specifically designed for gaming, our early internship with AMD's Ryzen 7 4700U showed that the 2-pound Yoga Slim 7 struggled with Borderlands 2 at 1080p even at lower game settings and 30 to expressed 35 frames per second.

When the resolution was reduced to 720p, frame rates improved for smoother performance. AMD will also offer other variants of its Ryzen H-series processors that compete directly with the Intel Core i-series, including Core i3, i5 and i7. Compared to its Intel rival, AMD has often boasted of the Ryzen's energy efficiency.

A leaked 3D Mark 11 benchmark of the Zen 2-based Ryzen 4000 processor based on the Renoir architecture was recently discovered on the desktop side and shows that the 4000G processor scores 5,659 points.

The score is right behind AMD's Ryzen 7 5800U mobile processors, which use a similar Renoir design based on Zen 2. The AMD Ryzen 7 4800U scored 6,309 points while the Ryzen 7 4700U scored 5,713 points.

AMD 4800H comparisonBeating Intel while playing on laptops would be a real game changer for AMD.

A possible explanation for the lower performance of the 4000G is that the leaked benchmark was tested with a slower DDR4-2133 MHz memory, although it operated with a higher TDP of 45-65 W than the 15 W upper limit of the mobile counterparts becomes. Faster memory could give Vega graphics a boost, according to Wccftech, and we still don't know much about the cores and configurations used in the early Zen 2-based Ryzen 4000 desktop processor for benchmark testing.

Ryzen 4000: desktop

On the desktop side, we are expecting two new variants of the Ryzen 4000 chipsets with staggered starts. AMD recently announced its first Ryzen 4000 desktop silicon based on the company's Zen 2 cores. This first Ryzen 4000 desktop APU, code-named Renoir, is essentially an enlarged version of AMD's Ryzen 4000 mobile processor.

The Zen 2-based Ryzen 4000 processors start with the Ryzen 3 4300GE, which is equipped with four cores and eight threads and a base clock speed of 3.5 GHz and scales up to a Ryzen 7 4700G, a processor with 3.6 GHz base speeds with eight cores and 16 threads, which are supplied with eight integrated graphics cores.

The consumer line is divided into the GE series, which require 35 W TDP, and a G series, which require 65 W TDP. The GE series includes the Ryzen 3 4300GE, Ryzen 5 4600GE and Ryzen 7 4700GE, while the G series includes the Ryzen 3 4300G, Ryzen 5 4600G and Ryzen 7 4700G.

According to AMD, these processors are only available on pre-made PCs, at least initially, so you can't upgrade your existing desktop to a Ryzen 4000 APU when it starts up.

The company also announced commercial variants of its desktop APUs, including Ryzen 3 PRO 4350G, Ryzen 5 PRO 4650G and Ryzen 7 PRO 4750G with 65 W TDP, and Ryzen 3 PRO 4350GE, Ryzen 5 PRO 4650GE and Ryzen 7 PRO 4750GE with 35 W. TDP, reported ZDNet.

As with its mobile counterparts, AMD supports the powerful graphics performance of these processors. The strength of the integrated GPU enables the company to play games without a discrete graphics card.

AMD's early internal benchmarks show an increase of between 99% and 274% in popular games compared to the Intel Core i7 9700 processor. Games used for comparison include titles such as CS: Go, Rocket League, Civilization VI and GTA V.

PCMag reported that the Ryzen 5 4600G performed between 39% and 100% better than the ninth generation Intel Core i5-9500 in multi-threaded content creation and content creation tasks, PCMag reported.

These processors only support PCIe 3.0, not the newer and faster PCIe 4.0 specifications.

A second desktop version of Ryzen 4000 will include an updated Zen 3 theme known as Vermeer. Vermeer will be based on a completely new architecture, according to Forrest Norrod, AMD's senior vice president. Like its rival Intel, AMD's chip releases will follow the tick-tock cadence, with the Zen 2 design forming the basis for the “tick” cycle.

Zen 3's token cycle comes with a new architecture and an expanded 7nm + process node. AMD could potentially rely on TSMC to manufacture this chip on its expanded 7nm node. In the Zen 3-based Vermeer version, AMD is said to focus on three key features for its silicon: IPC gains, faster clock speeds, and higher efficiency.

The Zen 3-based Ryzen 4000 desktop CPUs will not be such a drastic improvement, but they will bring some notable improvements. AMD has confirmed that it will be based on a new CPU architecture for Zen 3, and early reports from Wccftech suggest that this design could increase IPC by 17% and floating point operation by 50%.

AMD Epyc Milan Zen 3Source: AdoredTV

Based on the information we know about AMD's Zen 3 plans for the EPYC Milan processors intended for servers, we can derive similar changes to the new Vermeer architecture for desktops. AMD had confirmed that Zen 3 EPYC would benefit from a unified cache design. According to AdoredTV, the double L3 cache should be available for every Zen 3 core. Because of the new design, each core has the same access to the cache on the same chip, which results in more consistent performance. Hopefully these changes will also be ported to AMD's desktop silicon.

Early technical examples from Vermeer, obtained from Igor's Lab, showed that the chip can be equipped with a 16-core architecture with a 4.6 GHz boost clock rate and a base speed of 3.7 GHz . Notable details about Vermeer, however, could likely change when the chip starts up. Therefore this information should be taken up with a grain of salt. If Igor’s Lab is accurate, Vemeer is cheap compared to the Ryzen 9 3950X, which comes with 16 cores and 32 threads and has a maximum boost speed of 4.7 GHz and 3.5 GHz base speed.

The eight-core Zen 3 Ryzen engineering examples are said to have a base speed of 4 GHz and a boost speed of 4.6 GHz, which corresponds to an increase of 100 MHz compared to the Ryzen 7 3800X.

The Zen 3-based Ryzen 4000 is based on TSMC's 7nm + process node and is manufactured using the new extreme ultraviolet lithography process, which is intended to improve chip efficiency but also reduce production costs. The latest speculation suggests that Zen 3 will provide 20% higher transistor density than Zen 2 and will reduce power consumption by 10%.

In October, WCCFTech reported that Zen 3 enhancements would include lower cache latency and higher fabric speeds in infinity. This would help increase the IPC (instructions per cycle) by 8% over Zen 2 and provide an additional 200 MHz to 300 MHz per core. This should not only make Ryzen 4000 faster than its predecessors, but also allow AMD to be more competitive at clock speeds with Intel. We don't have much core count information yet, but since Zen 2 doubles Zen core count, we should expect Zen 3 to contain even more cores.

AMD has also suppressed a recent DigiTimes report that Ryzen 4000 may be moved to early 2021 so that AMD can skip the 7nm design for Zen 3 in favor of a smaller 5nm EUV node. Since the report was released, AMD TechPowerUp has clarified its product roadmap and found that rumors of a delay are inaccurate. The company also showed a presentation slide stating that Zen 3 will be based on a 7nm process.

AM4 socket

AMD Ryzen 9 3900xDan Baker / Digital Trends

One of the best features of AMD's Ryzen CPUs was that it supported the same AM4 socket across generations. This means that those who bought Ryzen CPUs and first generation motherboards were able to upgrade their processors without having to buy a new motherboard. You only need to update the BIOS. This will also be the case with Zen 3 Ryzen 4000 processors, although this will be the last generation of Ryzen chips that use the AM4 socket.

Tom's hardware reported that AMD reversed its decision to support Zen 3 desktop processors only on the latest B550 and X570 motherboards after a game. According to AnandTech, AMD has now announced that support for Zen 3 and Ryzen 4000 CPUs will be extended to the B450 and X470 motherboards.

"We have heard our audience and understand the concerns," said AMD of his plans. The company announced that it will be working closely with its motherboard partners to provide support through BIOS updates. "We'll find a way to support Zen 3 on our 400 series chipsets right up to launch. We're still working on what and how, but we'll update you closer to Zen 3 launch."

A recent leak on AMD's X670 chipset has shown that Zen 3 continues to support the AM4 socket. The X670 chipset is expected to be available in the fourth quarter of 2020 and will feature improvements such as enhanced support for PCIe Gen 4.0. It will also offer increased I / O from additional M.2, SATA, and USB 3.2 ports, although Wccftech reported that native Thunderbolt 3 support may still not be available on this chipset. AMD recently announced a budget-friendly B550 chipset that supports the AM4 socket and brings PCIe 4.0 support at a lower price.

Ryzen 5000, which is expected for 2021, will switch beyond AM4 to a new AM5 socket design based on technologies such as DDR5 memory and PCIe 5.0, according to Wccftech.

There will be a new motherboard chipset that will support the new Zen 3 chips immediately, but we have no details on what important new features we can expect from them.

Thread ripper

In early 2020, the inventory of Threadripper 3000 CPUs was just beginning to meet demand, so details about Ryzen 4000 Threadripper CPUs are almost non-existent. We'll have to wait and see what 4th generation Ryzen Epyc server CPUs look like before we can guess what Threadripper 4000 CPUs do.

As with Threadripper 2000, however, we would expect a more modest improvement in single-thread performance. It remains to be seen whether the number of cores will increase dramatically.

Updated July 24, 2020: Added launch information for the Ryzen 4000 desktop APU; added AMD's internal desktop APU benchmarks and 9th generation Intel comparisons; Added commercial pro brand Ryzen 4000 desktop APU.
