Our sources have finally given us the details of AMD’s impending Ryzen 7000 “Raphael Desktop CPUs based on the Zen 4 core,” and we can confirm that there will be four SKUs available at launch: the AMD Ryzen 9 7950X, Ryzen 9 7900X, Ryzen 7 7700X, and Ryzen 5 7600X.
According to our exclusive leak from the previous day, the AMD Ryzen 7000 Desktop CPU family, codenamed Raphael, will be on sale on September 15th after an announcement later in the month. Although the AMD Zen 4 architecture increases IPC by 8–10%, the majority of the performance gain comes from the faster clock rates and greater TDP that are added to each chip compared to the previous iteration. When comparing Zen 4 to Zen 3 cores, AMD has seen advances in single-threaded performance of over 15%, multi-threaded performance of over 35%, and per-watt performance of over 25%.
The CPUs will have an improved cache restructure with a shared L3 cache, a shared L2 cache, support for DDR5 memory with AMD’s Extended Profiles For Memory Overclocking, PCIe Gen 5.0 graphics card, and M.2 SSD support. Having stated that, let’s move on to the details.
The AMD Ryzen 9 7950X, which carries over the previous two generations’ healthy 16 core and 32 thread count
The processor will have a base frequency of an amazing 4.5 GHz and a maximum boost clock of 5.7 GHz, which should make it 200 MHz faster than Intel’s Alder Lake Core i9-12900KS, which has a single-core boost frequency of 5.5 GHz. It appears that AMD is getting as much Hertz out of the Ryzen 9 chips’ 170W TDP (230W PPT) as possible. The CPU has 80 MB of cache, of which 64 MB are from L3 (32 MB per CCD), and 16 MB are from L2 (1 MB per core).
The 7900X AMD Ryzen 9 chip, as its name suggests, would have 12 cores and 24 threads. The CPU has a boost rate set at 5.6 GHz across a single core and an even faster base clock of 4.7 GHz. The CPU receives 76 MB of cache (64 MB L3 + 12 MB L2) while maintaining its 170W TDP. The CPU will be comparable in price to the AMD Ryzen 9 5900X, but it will outperform the Core i7-12700K in terms of performance.
Here we have the AMD Ryzen 7 7700X, an 8-core and 16-thread component from the Ryzen 7 family. The CPU will have a base clock of 4.5 GHz and a boost clock of 5.4 GHz, but at a lower 105W TDP, since AMD sees this as the sweet spot for gamers (142W PPT). The CPU will receive a 40 MB cache pool, which is made up of 8 MB L2 and 32 MB L3 from the single Zen 4 core and CCD, respectively.
AMD has not yet released any updates for the Ryzen 7 7800X processor. It’s possible that AMD aims to replace that component with a Ryzen 7 5800X3D replacement with Zen 4 cores (3D V-Cache). If so, the CPU lineup will likely be updated later this year since AMD has confirmed that the V-Cache components will debut in the latter half of Q4 2022. Additionally, it appears that the Ryzen 7 7700X will be priced very competitively in the mainstream sector based just on segmentation.
