AMD’s upcoming Ryzen 9 9950X processor is slated to launch next month (31st of July), with reviews expected to arrive around the same time. A new leak from the AnandTech forums has revealed the vector performance of the Granite Ridge flagship. The 9950X was tested in the AIDA64 CPU ray-tracing benchmarks, highlighting massive gains over the Ryzen 9 7950X and existing Core i9 SKUs. We’re talking about 3x the performance offered by the Core i9-14900K and the 13900K.
In the CPU AES benchmark, the Ryzen 9 9950X scores 746991 MB/s. That’s nearly twice as fast as the 7950X, and 2.5x higher than the 294509 MB/s scored by Intel’s Core i9-13900K. That said, it’s important to note that AES is primarily related to security and cryptography, and the Ryzen chips seem to be utilizing AVX-512 Vector AES instructions (VAES) that aren’t supported on Raptor Lake.
The FP32 and FP64 ray-trace benchmarks produce even wider deficits between the Ryzen 9 9950X and contemporary Intel Core i9s. The Zen 5 flagship is 3.15x and 3.12x faster than the 13900K in the FP32 and FP64 simulations. This is again the result of AVX512 instructions supported by Zen 4 and Zen 5 (with wider FP/registers), and not their Intel rivals.
Linpack produces similar results, averaging ~1650 GFlops on the Ryzen 9 9950X, up from just 630 GFlops on the Core i9-13900K. This is again the result of AVX512 support on the AMD chips and the lack thereof on the latter.
