AMD Ryzen 7000 Raphael processor is rumored to have 16 cores per die
AMD CEO Dr. Lisa Su will give a keynote speech at CES 2022, and the rumors will also involve some details of the Zen 4 architecture desktop processor code-named Raphael. Previously, there were rumors that the Ryzen 7000 series products may be released on Computex 2022 in the middle of this year to replace the current Zen 3 architecture Ryzen 5000 series products, code-named Vermeer.
According to Wccftech reports, AMD may provide more cores on the Zen 4 architecture processor, whether it is a product codenamed Raphael, Phoenix, or Genoa. The CCD used by the Raphael processor will have up to 16 cores, 8 of which are Priority Cores running at full speed. The rest of the 8 Zen 4 cores will be Low-TDP optimized cores and operate at a combined TDP of 30W. Each Zen 4 ‘LTDP’ and ‘Priority’ core will share 1MB of L2 cache, totaling 8MB. Through the 3D vertical cache technology, a 64MB SRAM cache is stacked as the L3 cache of the processor.
If the Ryzen 7000 Raphael processor uses two CCDs, a 32-core design can be realized, with a total of 128MB of L3 cache. Rumored to have a 32-core Raphael processor, its TDP is the highest 170W. In addition, AMD’s design is different from Intel’s Alder Lake cores and does not require software to be specifically optimized for scheduling. Its LTDP will only be used after the Priority Core utilization reaches 100%. It is said that although the 8 LTDPs only have a TDP of 30W, their performance will be stronger than the current Ryzen 7 5800X processor.
Raphael will use the brand new AM5 socket (LGA 1718), manufactured by TSMC’s 5nm process, and IOD will use the 6nm process, integrated RDNA 2 architecture core, support PCIe 5.0 and dual-channel DDR5-5200 memory, providing a frequency of about 5GHz. In addition to supporting USB 3.2, the new platform may also have native USB 4.0.
