AMD Instinct MI350P vs AMD Ryzen Z2 GPU Comparison

The Verdict

The AMD Instinct MI350P and AMD Ryzen Z2 GPU occupy entirely different segments of the hardware spectrum, and the recorded data makes the separation unambiguous. The MI350P is a compute-oriented accelerator built on CDNA 4.0 with a 600 W TDP, 144 GB of HBM3e memory, and 36.04 TFLOPS of FP32 throughput. The Ryzen Z2 GPU is a 28 W RDNA 3.0 integrated graphics solution with 16 GB of LPDDR5X, 8.294 TFLOPS FP32, and full DirectX 12 Ultimate API support. The MI350P targets high-throughput compute workloads where memory capacity and bandwidth dominate. The Ryzen Z2 GPU targets portable or embedded systems requiring graphics output and API compatibility. Neither part serves the other's purpose, and the data indicates no overlap in intended deployment. The MI350P has no display outputs and no API support for DirectX, OpenGL, or Vulkan. The Ryzen Z2 GPU provides a USB Type-C display output and supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. The choice between them is determined by workload type, not performance tier.

Head-to-Head Benchmarks

The recorded benchmark suite contains no direct head-to-head measurements, so the comparison relies on the specification-derived performance indicators in the database. The MI350P delivers 36.04 TFLOPS FP32, which is 4.35 times the Ryzen Z2 GPU's 8.294 TFLOPS. The FP16 figures match the FP32 ratios exactly for both parts, with the MI350P at 36.04 TFLOPS and the Ryzen Z2 GPU at 8.294 TFLOPS. The MI350P's texture rate of 1,126.4 GTexel/s is 8.69 times higher than the Ryzen Z2 GPU's 129.6 GTexel/s. The Ryzen Z2 GPU counters with a pixel rate of 86.40 GPixel/s, while the MI350P reports 0 MPixel/s, reflecting its lack of a rasterization pipeline. Memory bandwidth shows the largest gap: the MI350P's 8.19 TB/s is 68.3 times the Ryzen Z2 GPU's 119.9 GB/s. The MI350P carries 144 GB of memory versus 16 GB for the Ryzen Z2 GPU, a 9-fold capacity advantage. The Ryzen Z2 GPU has a higher boost clock at 2700 MHz versus 2200 MHz for the MI350P, and a higher base clock ratio, with 800 MHz versus 1000 MHz giving the MI350P a 25% higher base clock. The Ryzen Z2 GPU's 12 ray tracing cores provide hardware RT capability that the MI350P does not list. The MI350P's 8192 shading units outnumber the Ryzen Z2 GPU's 768 by a factor of 10.67. The TMU count of 512 versus 48 is a 10.67 ratio as well. The ROP count of 0 for the MI350P versus 32 for the Ryzen Z2 GPU shows the fundamental architectural divergence: the MI350P is not designed for pixel output, while the Ryzen Z2 GPU is a full graphics processor.
