AMD launches Zen 3+ architecture Ryzen 6000 series mobile processors
At the CES 2022 conference, AMD brought the Ryzen 6000 series mobile processor, code-named Rembrandt, as scheduled, as well as the Zen 3 desktop processor equipped with 3D V-Cache, the Zen 4 processor was also mentioned at this conference, but only very little information was revealed.
The Rembrandt production process of the Ryzen 6000 series mobile processor is upgraded from TSMC 7nm to 6nm, and the CPU core is also upgraded from Zen 3 to Zen 3+, GPU jumps directly from the Vega architecture to the latest RDNA2 architecture, and will also support new features such as PCI-E 4.0, DDR5 memory, USB4, and WiFi 6E.
Thanks to the latest technology, the Ryzen 6000 mobile processor has a maximum frequency of 5GHz, and its performance will be 30% higher than the previous generation Ryzen 5000 series, and the GPU performance is more than twice that of the previous generation.
The Ryzen 6000 series mobile processors can have up to 8 Zen 3+ cores, and the improved 6nm process makes the processor’s energy consumption ratio significantly improved. Compared with the previous generation of processors, the Zen 3+ core has added 50 new power management functions and added a new sleep state, known as the “Z” state, it can reduce the power consumption of the core to a very low range, and the system management firmware has been redesigned to make it more intelligent. There are more on-chip sensors that enable faster and more accurate power consumption control of the core.
The core graphic of the Ryzen 6000 series mobile processor can have up to 12 sets of RDNA 2 CU units and supports hardware-level ray tracing. This is the first core graphic that supports optical tracking. The GPU frequency can reach up to 2.4GHz, and thanks to the latest DDR5 memory, the memory bandwidth is increased by 50% compared to the previous generation, and this core graphic also supports AMD FSR, which can further improve game fluency.
In terms of peripheral interfaces, Rembrandt supports the latest USB4 interface with a bandwidth of up to 40Gbps. There are 20 PCI-E 4.0 channels, of which 8 are used to connect to a dedicated display, 4 are used to connect to an NVMe SSD, 4 are general-purpose PCI-E, and 4 can be used for NVMe or SATA interfaces. The memory controller can support LPDDR5-6400 or DDR5-4800, support the WiFi 6E solution cooperating with Qualcomm and MediaTek, support HDMI 2.1 and DisplayPort 2 interfaces, and support AI noise reduction to filter background noise.
Ryzen 6000 series notebook processors include a total of 8 H series processors and 2 U series processors. There are only 8 cores and 6 cores, and no 4-core products, and this time the core display is directly drawn into 12 groups of CU and 6 groups of CU, and there are no other intermediate products. In addition, there are three new Ryzen 5000U series processors, the Barcelo mentioned earlier, which is not much different from the existing Cezanne.
In terms of performance, the video editing efficiency of the Ryzen 7 6800U is 1.7 times that of the previous generation Ryzen 7 5800U, the 3D rendering efficiency is 2.3 times, and the game performance is twice the performance. The performance improvement is very obvious.
In terms of power consumption, the Ryzen 6000 series reduces power consumption by 30% compared with previous generation products during video conferencing, while web browsing power consumption is reduced by 15%, and power consumption when watching streaming media is reduced by as much as 40%.
