AMD Rembrandt

Over the past few years, AMD has introduced four generations of laptops to laptops APU processors, based on the Zen architecture and offering integrated Vega chips. With each successive generation, the performance of the cores increased (Ryzen 2000 – Zen; Ryzen 3000 – Zen +; Ryzen 4000 – Zen 2; Ryzen 5000- Zen 3) as well as the performance of integrated graphics systems. Nevertheless, we waited for a real breath of fresh air, especially in the subject of iGPU systems. The Vega architecture, although energy-efficient, has over the last few years been overwhelmed by everyone. That was supposed to change this year with the introduction of the fifth-generation APU Rembrandt. The most important change is the change of the graphics chip, based on the Vega architecture, to the graphics chip RDNA 2. At today’s conference, AMD has finally revealed the details of the new project. There was also information about the Ryzen 7 5800X3D consumer processor with 3D V-Cache and the Raphael generation, based on the Zen 4 microarchitecture.

AMD officially introduces the new generation APU for laptops. Ryzen 6000U / H processors offer even more powerful Zen 3+ cores and new integrated RDNA 2 graphics chips. HDMI 2.1, DisplayPort 2.0, DDR5, PCIe 4.0 and AV1 codec.

The first laptops with Ryzen 6000 processors from the Rembrandt family will be available for sale at the beginning of February. The manufacturer has prepared a total of 10 units: Ryzen 9 6980HX, Ryzen 9 6980HS, Ryzen 9 6900HX, Ryzen 9 6900HS, Ryzen 7 6800H, Ryzen 7 6800HS, Ryzen 7 6800U, Ryzen 5 6600H, Ryzen 5 6000HS and Ryzen 5 6600U. All processors are equipped with Zen 3 cores +, RDNA 2 graphics chips and a large set of new functionalities will make the Rembrandt APU the most modern processor in notebooks. There is also support for DDR5-4800 and LPDDR5-6400 memory, as well as PCIe 4.0, USB 4 (40 Gb / s), HDMI 2.1, DisplayPort 2.0, AV1 and HDR codec (also Dol by Vision).

Thanks to further optimizations of the Zen 3 cores (now called Zen 3+), the manufacturer we managed to increase the efficiency of a single core by 11% and multithreaded efficiency by almost 30% (comparison of Ryzen 7 5800U – Cezanne APU to Ryzen 7 6800U – Rembrandt APU). In addition, thanks to further changes in Power Management, laptops with new Rembrandt units will be able to work even longer on battery power, reaching the level of even a full day (24 hours). It is also due to the lower technological process – 6 nm turns out to be even a dozen or so percent more energy-efficient compared to the currently used 7 nm lithography.

The real creme de la creme in APU Rembrandt, however, will be an integrated graphics chip, based on the RDNA 2 architecture. It is to offer up to twice the performance in games, which will be even more intensified by the support for the AMD FidelityFX Super Resolution technique. The Rembrandt APU will also be the first processor of this type to support Ray Tracing computing in hardware. RT can be activated on AMD Ryzen 6000U / H processors without the need for a separate graphics card. In this case, however, it will be good to use the FSR technique.

IN compared to iGPU Vega, iGPU RDNA 2 will have, among others twice the L2 cache and much higher core clocks, reaching 2400 MHz. For example, in DOOM Eternal, the new iGPU RDNA 2 will be up to 3x more efficient compared to Intel Iris Xe Graphics (96 EU) – if actual tests confirm such a big leap in performance, it will be a really huge leap forward for iGPU. Thanks to the additional support for FSR, the AMD Ryzen 7 6800U APU will be able to achieve over 60 FPS in games such as Far Cry 6, Call of Duty Vanguard, Deathloop or Godfall, of course in Full HD resolution and maintaining low / medium graphics settings.

During The company’s presentation also included awaited information on Ryzen processors with 3D V-Cache. However, it looks like the company will only release one such chip – the Ryzen 7 5800X3D. Its specification was revealed during the conference. It will be an 8-core and 16-thread processor with a base clock of 3.4 GHz, rising to 4.5 GHz in Turbo mode. It will offer 32 MB of basic L3 cache and an additional 64 MB 3D stack. As a result, the processor will offer a total of 96 MB L3 cache, which in extreme cases will translate into even several dozen percent increase in gaming performance. The biggest beneficiary here seems to be the Watch Dogs Legion game, in which the performance increase on the AMD Ryzen 7 5800X3D processor is to reach 36% compared to the Ryzen 9 5900X. Thanks to the use of 3D V-Cache, the new chip is to be competitive with the Intel Core i9-12900K. AMD Ryzen 7 5800X3D (AM4 Compatible) will be released in Spring 2022.

Lisa During the presentation, Su also gave us a first look at the Ryzen 7000 processor from the Raphael family. It will be based on the Zen 4 architecture and will use TSMC’s 5nm technological process. The design of the processor itself and support for PCIe 5.0 and DDR5 memory were also confirmed. Ryzen 7000 processors will be the first, prepared for the LGA 1718 (AM5) socket. The new generation of Ryzen “Zen 4” will be available in the second half of 2022, as will the AM5 stand.
