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. The aim of AMD is to use the Ryzen 4000 processors of the U series to produce laptops that are as powerful as they are thin, 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 the last part of the year.
Here you will find everything we know about AMD Ryzen 4000 CPUs.
Prices and release date
AMD presented the first Ryzen 4000 CPUs at CES 2020, 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. The Yoga Slim 7 will come with a 14-inch display for $ 850. Here you get a eight-core Ryzen 7 4700U processor in a 2.2-pound form factor that competes with Ultrabooks with Intel processors. The Inspiron 14 7000 2-in-1 convertible from Dell will also be available in Ryzen 4000 configurations. Lenovo also announced that a wide range of its commercial ThinkPad notebooks can also be configured with the mobile AMD processor.

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 are planned for this spring.
Desktop Ryzen 4000 CPUs with Zen 3 architecture are expected to arrive later this year. Recent rumors from Wccftech suggest that these processors will be available in October. However, an announcement could be made earlier in August or September. More recently, Tom's hardware reported that DigiTime's sources told motherboard manufacturers that the desktop Ryzen 4000 CPUs could arrive at the Computex show. Although the physical show has now been canceled after being pushed back from its traditional late spring date, AMD, like many of its tech colleagues, could switch to a purely online format and host a live streaming event to showcase its processors.
Interestingly, AMD could introduce its Zen 3-based Ryzen 4000 processors along with its new RDNA 2-based Radeon RX Navi 2x graphics card. The Ryzen chips will have several performance improvements. However, AMD has not yet announced any models or pricing information. We would expect a similar premium to the current Ryzen 3000 series, with CPUs ranging from $ 100 to around $ 750 for the most powerful multithreaded CPUs.
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 of the infinity structure from system memory.
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 increased 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 7nm design, AMD can reduce power consumption in active and idle modes. Latency has also been reduced, so laptops benefit from faster start-up times, faster applications, and better 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, it 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.

The mobile Ryzen 4000 CPUs should have a significant performance increase over 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 a much greater consistency and stability of the frame rate.
|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 aging 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 coded 40% faster on the Ryzen 4000 than on the Intel Quad-Core Core i7-10510U. 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 compared to 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. You will compete against the new Intel Ice Lake and the upcoming mobile Tiger Lake processors with the more powerful integrated graphics from Gen 11. When gaming on Fortnite, AMD claimed that its graphics outperformed Intel by 21% in its tests. AMD's lead in 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 exceeded 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. The laptop processor from AMD can hold its own against Intel in important office tasks, but the newer mobile mainstream processors from Intel 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 claims the overall performance can be 60 frames per second for a number of high-end titles 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 first practical exercises with the Ryzen 7 4700U AMD phone showed that the 2-pound Yoga Slim 7 struggled with Borderlands 2 at 1080p even at lower game settings had and 30 tons pressed out 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 the 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 places it directly 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.
Beating 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. The first version, which is expected to be released in the coming months, should be based on an architecture with Zen 2 cores. This architecture, codenamed Renoir, was recently discovered in the wild by Twitter user @_rogame on a Gigabyte B550 AORUS PRO AC motherboard.
In the early CPU example, the processor cores were clocked at 3.5 GHz and a GPU at 1750 MHz, similar to the speeds that AMD had used on its Ryzen 7 4800H and Ryzen 9 4900H processors. The similarities here could mean that the Ryzen 4000 Renoir design could be delivered with an 8-CU design with 512 cores, Wccftech speculated, with the improved Vega chip giving it a graphics boost over the 12nm Ryzen 3000G series .
German publication Igor & # 39; s Lab speculated that the Renoir range of Ryzen 4000 desktop processors will include the Ryzen 3 4200G and Ryzen 5 4400G in addition to the Ryzen 7 4700G. The site also claimed that Renoir will support a fabric clock of up to 2,000 MHz or a 200 MHz increase in fabric clock or FCLK on AMD's Ryzen 3000 series processors, suggesting that the APU DDR4 memory modules are running at speeds of up to 4,000 could use MHz.
It is currently unclear whether Renoir supports PCIe 4.0. A current product page for the Biostar Racing B550GTA motherboard indicates that PCIe 4.0 may not be supported. In the motherboard specifications, Biostar stated that PCIe 4.0 support "depends only on Ryzen 3rd Gen Matisse" and "PCIe 4.0 speed only for AMD Ryzen 3rd Gen Matisse".
A second desktop version of Ryzen 4000 is expected later this year, which will include an updated Zen 3 design called Vermeer. According to Forrest Norrod, senior vice president of AMD, Vermeer will be based on a completely new architecture. 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 that drastic an 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%.
Based on the information we know about AMD's Zen 3 plans for EPYC Milan processors designed 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 . Remarkable 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 technical Zen 3 Ryzen examples with eight cores 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 said 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's improvements 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 enable AMD to be more competitive at clock speeds with Intel. We don't have much core number information yet, but since Zen 2 doubles Zen core count, we should expect even more cores with Zen 3.

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 could upgrade their processors without having to buy a new motherboard. You just 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 & # 39; s Hardware reported that AMD reversed its decision to support Zen 3 desktop processors only on the latest B550 and X570 post-game motherboards. According to AnandTech, AMD has 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 work 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.
According to Wccftech, Ryzen 5000, which is expected in 2021, will switch beyond AM4 to a new AM5 socket design, which is said to be based on technologies such as DDR5 memory and PCIe 5.0.
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.
In early 2020, the inventory of Threadripper 3000 CPUs just started to meet demand, so details about Ryzen 4000 Threadripper CPUs are almost non-existent. We'll have to wait and see what fourth 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.
