During ces 2022, AMD unveiled the Ryzen 6000 series of mobile processors, codenamed Rembrandt, covering a variety of mobile product lines such as high-performance game books, thin and light game books, thin and light books, and business books. Prior to the release of notebooks based on rembrandt, a Ryzen 6000 series mobile processor, PConline participated in a media conference held by AMD, and Robert Hallock, AMD's director of technology marketing, introduced the new generation in detail.
Overall, the main points of upgrading the Rembrandt 6000 series mobile processors include four dimensions: the improved Zen 3+ processor core microarchitecture, the built-in nuclear display integrating the new RDNA 2 architecture, the TSMC 6nm process, and the overall innovation of the platform.
The Ryzenne 5000 series mobile processor Cezanne released last year uses the Zen 3 microarchitecture, and the Zen 3+ microarchitecture used in the Ryzen 6000 series processor Rembrandt is equivalent to an upgraded and optimized version of the former, combined with the TSMC 6nm process, while meeting the high performance and committing to achieving higher energy efficiency.
At the optimization level of microarchitecture, Robert Hallock said that the CPPC coprocessor performance control technology has been further improved, which can be upgraded from per-core control to per-thread control, which can more accurately adjust the frequency and power consumption according to the load of each thread; and PC6 Restore is a new processor hardware assistance function, which can allow the CPU core and the circuit around the core to enter and jump out of the deepest low-power state. And this is 4 times faster than last year's product jumping in and out, through this feature, you can make full use of the CPU's deepest low-power power state, and you can do the switching more often.
Robert Hallock also emphasized that Rembrandt also offers many new features at the overall SOC level, implementing a new power consumption management architecture that can precisely regulate individual components in the chip. In addition, a new area has been added, and a new module in this area allows the display controller to switch independently, a technique called the "Z" state. At the same time, there is a new mechanism in the IF bus, introducing a new power mode, so that the data bus can be shut down, but the system can continue to operate.
In terms of specific product parameters, the Ryzen 6000 series mobile processor Rembrandt is mainly divided into three sub-series, the U series for thin and light books, TDP power consumption in 15-28W, HS series for thin and light game books, TDP power consumption at 35W, H series for traditional game books, TDP power consumption at 45W, of course, also includes 45W + TDP products with the suffix HX.
The most significant change in Rembrandt compared to Cezanne is the increase in frequency, of which the flagship Ryzen™ 9 6980HX is 8 core 16 threads, 16MB three-level cache, and the highest single-core turbo frequency can reach 5.0GHz; the main model of the shipment, the Ryzen 9 6900HX single-core turbo, is 4.9GHz, and the Ryzen 7 6800H also has 4.7GHz, which is higher than the corresponding models.
In terms of specific performance, the official gave a data comparison, the 45W Ryzen™ 9 6900HX compared to the Ryzen™ 9 5900HX, in the Blende, Cinema 4D and LAME MP3 Encoder and other applications have been up to 47% improvement, compared to the 65W Intel 11th generation Core processor Tiger Lake-H performance advantage is greater.
In terms of game performance, the official use of the Ryzen 9 6900HS + AMD Radeon RX 6800S and the Ryzen 9 5900HX + RTX 3080 two platforms for comparison, the frame rate can be increased by more than 10%.
Of course, the GPU part is the focus of Rembrandt's upgrade, the entire series is equipped with RDNA 2 architecture Radeon 600M series built-in graphics cards, of which Ryzen™ 7, Ryzen™ 9 and other high-end models equipped with 12CU Radeon 680M, Ryzen 5 is equipped with 6CU Radeon 660M.
For thin and light books, the performance of the built-in graphics card directly affects the user experience. AMD officials said that the Radeon 680M integrated by the Ryzen 6000 series mobile processor Rembrandt is more powerful than the 96EU Sharp Torch Xe of the 11th generation Core processor Tiger Lake-UP3, and can run online games at a high frame rate of 1080P resolution.
AMD officially uses the Radeon 680M graphics card built into the Ryzen™ 7 6800U, which is close to the overall performance compared with the GTX 1650 Max-Q display.
After turning on the FSR technology, the Radeon 680M built-in graphics card can catch up with or even surpass the GTX 1650 Max-Q in some games.
In addition to TSMC's 6nm process, Zen 3+ microarchitecture improvements, and significant improvements in the RNDA 2 built-in graphics card, The Ryzen 6000 series mobile processor Rembrandt has also made significant changes in terms of platform, such as supporting USB 4 40Gbps, PCIe 4.0, DDR5-4800 and LPDDR5-6400 memory, Wi-Fi 6E unlimited network, DisplayPort 2.0 video output, etc. In terms of IO, it has greatly compensated for the shortcomings left by the previous two generations of Renoir and Cezanne.
At the end of the communication meeting, Robert Hallock said that it is expected that by the end of 2020, there will be 200 notebook products equipped with Ryzen™ 6000 series processors on the market, covering high-performance game books, thin and light game books, thin and light books, business books and other product lines. Both gamers and content creators can choose the right product for them.
