At CES 2022, AMD unveiled the Ryzen 6000 series of mobile processors, code-named Rembrandt. The Zen 3+ microarchitecture, built on TSMC's 6nm process, further improves the turbo upper limit and energy efficiency compared to the Cezanne, a ryzen 5000 series mobile processor, such as the flagship model Ryzen 9 6980HX with a maximum single-core turbo frequency of 5.0GHz, which is the first Ryzen processor to reach a frequency of 5.0GHz.
Although the game model equipped with AMD Ryzen™ 6000 series mobile processor Rembrandt has not yet been fully released, foreign media Videocardz has found the relevant benchmark performance test results of this series of processors in the official database of Geekbench 5.
The specific model is Ryzen 9 6900HX, which is the sub-flagship of the Rembrandt series, providing 8 core 16 thread specifications, the base frequency is 3.3GHz, the highest single-core turbo frequency is 4.9GHz, which is one times lower than the 5.0GHz of the Ryzen 9 6980HX; of course, the HX series is an unlockable model, and the OEM manufacturers set the power wall of the processor according to the cooling conditions of the model to show different performance. The test model in this database is identified as LENOVO 82RG, which not only carries the Ryzen™ 9 6900HX processor, but also installs the Windows 11 Pro operating system, the power plan is Balanced Mode, and the test time is Geekbench 5, which runs on January 25, 2022, with a specific version number of 5.3.2.
In terms of scores, the Ryzen™ 9 6900HX single-threaded 1593 and multi-threaded 10151 were tested.
Compared with the sub-flagship Ryzen 9 5900HX in the AMD Ryzen 5000 series mobile processor Cezanne, the Ryzen 9 6900HX has a 12% increase in single-threaded performance and a 33% increase in multi-threaded performance. The single-threaded increase is slightly greater than the frequency increase, and it can be found that Zen 3+ still has a little IPC growth; as for the multi-threaded improvement, the increase is more significant, considering that some of the sub-items in the Geekbench 5 multithreaded test are more sensitive to memory bandwidth, so the higher frequency DDR5 memory is also indispensable.
By slightly improving the architecture and optimizing the process to increase the frequency, in fact, AMD Ryzen 6000 series mobile processor Rembrandt has further tapped the performance under the premise of inheriting the Zen 3; at the same time, it has also made comprehensive improvements for the platform as a whole, including RDNA 2 architecture nuclear display, support for the new generation of DDR5-4800 or LPDDR5-6400 memory, PCIe 4.0 protocol, USB4, DisplayPort 2.0, Wi-Fi 6E, Features such as the Microsoft Pluton security processor and AI noise reduction filter out background noise can all enhance the comprehensive user experience.
Although there is a certain improvement over the previous generation, in 2022, AMD Ryzen™ 6000 series mobile processor Rembrandt will face a powerful opponent, that is, Intel's 12th generation Core processor high-performance mobile version of Alder Lake-H. Recently, there have been a large number of games equipped with Alder Lake-H on sale, compared to the test results in Geekbench 5, Ryzen™ 9 6900HX facing the Core i9-12900H and even the lower positioning of the Core i7-12700H are facing a backward situation, or a little bit insufficient...
If you do not consider the nuclear display, heat dissipation ability of the high-end game platform, with the mold of Rembrandt compared to Alder Lake-H is difficult to occupy the performance advantage, unless the AMD version can do a very powerful price.
However, the biggest upgrade point of AMD Ryzen 6000 series mobile processor Rembrandt is actually the integrated RDNA 2 architecture core display, completely abandoning the old GCN architecture; more importantly, models like Ryzen 9 6900HX, Ryzen™ 7 6800H and low-voltage Ryzen™ 7 6800U also have a full-blood 12CU computing unit (Ryzen™ 5 6600U cut in half, more disappointing), combined with the high bandwidth of LPDDR5-6400 memory. Graphics performance is very much worth looking forward to (the previously revealed 3DMark Time Spy graphics benchmark score reached 2700 points, surpassing the GTX 1050 Ti), there is an opportunity to completely replace the NVIDIA MX450, MX350 and other entry-level low-power unique displays, will also be more powerful than the Intel 96EU Iris Xe core display, in the thin and light market will have great attraction, consolidate the previously won market share.
It is expected that at the beginning of next year, AMD will release the Ryzen™ 7000 series mobile processor (code name should be Phoenix), which will be upgraded to a 5nm process and Zen 4 microarchitecture to achieve a real comprehensive replacement; at the same time, the mobile version of Intel's 13th generation Core Raptor Lake will also be released to further optimize the hybrid architecture of large and small cores; in the past two years, we will witness more and greater processor performance improvements in the thin and light and game markets.
