New AMD Strix Point leak shows significant gains in cache size, core count and iGPU performance compared to Zen 4 Phoenix APU

AMD is rumored to follow the Ryzen 7040HS Phoneix APU and Ryzen 7040HS Phoneix APU with the Ryzen 8000 Strix Point and Strix Halo APUs. For the uninitiated, the AMD Strix Point and Strix Halo APUs are a combination of Zen 5/5c processor cores and RDNA 3.5 or 3+ iGPUs. Both APUs are expected to appear in laptops next year. In addition to the growing pile of information about Strix Point, the source of information All_The_Watts shared the Strix Point APU specs on Twitter, which seem to confirm a lot of what we’ve already heard.

To begin with, All_The_Watts claims that the Strix Point APUs will have up to 4 large Zen 5 processors and 8 small Zen 5c cores, for a total of 12 cores. Since the Zen 5c cores support hyperthreading, the total number of threads for the 12-core Strix Point APU is expected to be 24. There will be two CCXs or clusters of cores.

In terms of cache size, the Zen 5 CCX appears to have a 4MB L2 cache and a 16MB L3 cache, while the Zen 5c CCX is expected to have an 8MB L2 and L3 cache . Thus, Strix Point APUs can have a total of 24 MB of L3 cache and 12 MB of L2 cache. By comparison, Phoenix’s top APU, the Ryzen 9 7940HS, has 8MB of L2 cache and 16MB of L3 cache.

All_The_Watts also claims that the Strix Point will have 8 WGP/16 CU RDNA 3+ iGPUs. In other words, the Strix Point iGPU can pack 33.33% more processors than the Radeon 780M inside the Phoenix APU, which has 12 CUs. If this increase results in significant improvements in graphics performance, next year could be a turning point for integrated graphics cards, as Intel has also announced significant improvements for the Xe LPG iGPU Meteor Lake.

The AMD Strix Point is also said to be equipped with 64 AI Engine cells, significantly expanding the on-chip AI capabilities. For reference, the XDNA AI accelerator inside the Phoenix APU has a total of 20 tiles.

Finally, All_The_Watts claims that the Strix Point has a 28-35+ W TDP with DDR5-6400/LPDDR5X-8533 memory speeds supported.

In short, AMD’s Strix Point APUs seem to be a big step up from the Zen 4 Phoenix processors in terms of core count, cache size, and iGPU. However, this information is not conclusive and it remains to be seen how accurate it is.
