Latest Zen 4 leaks: 8-core Ryzen 7000X CPU pops up on OpenBenchmarking, estimated performance gains over Zen 3 revealed by MLID
The upcoming Zen 4 “Raphael” Ryzen 7000X desktop processors from AMD are rumored to launch this September, with samples already being tested and production scheduled for June. A pre-production sample recently appeared in the Openbenchmarking database (already removed), which is linked to the Phoronix Test Suite, as reported by Videocardz. This means that the Raphael sample was tested in a Linux environment (Ubuntu 20.04), and it looks like most of the tests focused on the integrated GPU. On top of this, Moore’s Law Is Dead just released some expected performance gains for the Ryzen 7000X models.
The OpenBenchmarking database entries present an 8-core / 16-thread Zen 4 model with OPN code 100-000000666 matching a previous leak from January. Apparently, it has been tested on May 4 with an AMD Splinter-RPL reference AM5 platform and its maximum boost clock can go as high as 5.21 GHz. Videocardz notes that the iGPU features the GFX1036 ID that is a new variant pertaining to the Beige Goby / Yellow Carp / Van Gogh RDNA2 family. There is also a Radeon HD audio codec borrowed from the newly-released Rembrandt Ryzen 6000 mobile processors.
Unfortunately, the tests were not run at peak GPU clocks and were most likely performed for compliance purposes only, so we cannot really compare the results with similar Nvidia and Intel models. According to Videocardz, the Ryzen 7000X iGPUs are not even supposed to be gaming-capable, but they should offer basic media decoder capabilities.
MLID’s leak, on the other hand, is packed with impressive claims. First of all, Zen 4’s IPC increase over Zen 3 is expected to be between 15% and 24%, which is around 6% higher compared to the Zen 3’s gains over Zen 2. Clock increase would also see 8-14% gains, and both these aspects combined could lead to 28-37% performance increase in single core mode, while multi-thread performance increase is expected to be even higher. AMD is also introducing 1 MB L2 cache per core instead of 512 KB, and default RAM speeds are set to DDR5-5200 specs.
Besides the Raphael, Dragon Range and Phoenix models already teased officially by AMD, MLID also mentions the launch of a Threadripper 7000 family codenamed “Storm Peak,” which features up to 96 cores. However, these models are not expected to launch sooner than Q2 2023.
