AMD Instinct MI325X vs AMD Ryzen Z2 Extreme GPU Comparison

The Verdict

The database places these two AMD parts at opposite extremes of the compute spectrum. The AMD Instinct MI325X is a data center accelerator with no display outputs, designed for massive parallel workloads. The AMD Ryzen Z2 Extreme GPU is a 28 W console-class integrated graphics solution with a single USB Type-C output, aimed at portable gaming devices. Benchmark data exists only for the Ryzen Z2 Extreme GPU, which scores 516 in 3DMark Steel Nomad DX12 and sits at the 1st percentile among all GPUs. The Instinct MI325X has no recorded benchmark scores, placing it at the 50th percentile by default, but its raw specifications indicate a fundamentally different performance class. Users requiring rendering, gaming, or general-purpose graphics should look to the Ryzen Z2 Extreme GPU; users requiring high-throughput compute for AI or scientific workloads should look to the Instinct MI325X. The data does not support a direct comparison of their gaming performance because the Instinct MI325X lacks any graphics API support.

Architecture Differences

The Instinct MI325X uses the CDNA 3.0 architecture on the Aqua Vanjaram chip, fabricated on a 5 nm process at TSMC. It belongs to the Instinct (MIx) generation. The Ryzen Z2 Extreme GPU uses the RDNA 3.5 architecture on the Strix Point chip, fabricated on a 4 nm process at TSMC, and belongs to the Console GPU (AMD) generation. The transistor counts differ substantially: the Instinct MI325X packs 153,000 million transistors on a 1017 mm² die, while the Ryzen Z2 Extreme GPU contains 34,000 million transistors on a 233 mm² die. Transistor density is comparable, at 150.4 million per mm² for the Instinct MI325X and 145.9 million per mm² for the Ryzen Z2 Extreme GPU.

The Instinct MI325X has 19,456 shading units, 1,216 texture mapping units, and no ROPs, with a pixel rate of 0 MPixel/s. It has no ray tracing cores. The Ryzen Z2 Extreme GPU has 1,024 shading units, 64 texture mapping units, and 48 ROPs, with a pixel rate of 129.6 GPixel/s. It includes 16 ray tracing cores. The Instinct MI325X reports no graphics API support for DirectX, OpenGL, or Vulkan, while the Ryzen Z2 Extreme GPU supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The Instinct MI325X uses an OAM Module slot width with no power connectors, while the Ryzen Z2 Extreme GPU has no slot width specified and no power connectors.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between these two products. The only recorded benchmark for either part is the Ryzen Z2 Extreme GPU's 3DMark Steel Nomad DX12 score of 516. This score places it at the 1st percentile among all GPUs. Its nearest rivals in the database are older discrete parts: the Intel HD Graphics P4000 scores 534, which is 3.4% higher, and the AMD Radeon HD 6870 scores 536, which is 3.7% higher. The AMD Radeon HD 6750M scores 484, which is 6.6% lower, and the AMD Radeon HD 6770M scores 569, which is 9.3% higher. These deltas indicate that the Ryzen Z2 Extreme GPU performs in the range of a decade-old entry-level discrete graphics card, despite being an integrated solution. The Instinct MI325X has no comparable benchmark entry, so its performance relative to the Ryzen Z2 Extreme GPU cannot be quantified from recorded data. Its specifications, however, show a peak FP32 throughput of 81.72 TFLOPS versus 5.530 TFLOPS for the Ryzen Z2 Extreme GPU, and a texture rate of 2,553.6 GTexel/s versus 172.8 GTexel/s.

Where Each One Wins

The AMD Ryzen Z2 Extreme GPU wins in situations requiring graphics API compatibility, portability, and low power draw. It supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, making it suitable for gaming and general graphics workloads. Its 28 W TDP allows deployment in compact, battery-powered devices. Its 16 ray tracing cores enable hardware-accelerated ray tracing, a feature absent from the Instinct MI325X. Its 48 ROPs and 129.6 GPixel/s pixel rate support rasterization tasks. Its 5.530 TFLOPS FP32 throughput, while modest, is sufficient for integrated graphics in a handheld or low-power console context. The database records a 3DMark Steel Nomad DX12 score of 516, which places it near the Intel HD Graphics P4000 and AMD Radeon HD 6870 in performance, indicating it can handle older or less demanding titles at playable settings.

The AMD Instinct MI325X wins in raw compute throughput and memory capacity. Its 81.72 TFLOPS FP32 and FP16 (1:1) performance, 2,553.6 GTexel/s texture rate, and 6.14 TB/s memory bandwidth position it for high-performance computing, machine learning training, and large-scale data processing. Its 256 GB HBM3e memory on an 8192-bit bus vastly exceeds the Ryzen Z2 Extreme GPU's 16 GB LPDDR5X on a 128-bit bus. The Instinct MI325X has no ROPs and no pixel rate, confirming it is not designed for rasterized graphics output. Its 1000 W TDP and OAM Module form factor indicate a server environment with dedicated power delivery and cooling. The absence of display outputs and graphics API support reinforces its role as a compute accelerator rather than a rendering device.
