The AMD Radeon Instinct MI25 is a compute accelerator built around the Vega 10 GPU, using the GCN 5.0 architecture on a 14nm process from GlobalFoundries. It integrates 12,500 million transistors on a 495 mm² die, with a transistor density of 25.3M per mm². The memory subsystem is 16GB HBM2 on a 2048-bit bus, running at 852 MHz with an effective rate of 1704 Mbps, for 436.2 GB/s of bandwidth. The GPU has 4096 shading units, 256 texture mapping units, and 64 ROPs, with base and boost clocks of 1400 MHz and 1500 MHz. This produces a texture rate of 384.0 GTexel/s, a pixel rate of 96.00 GPixel/s, 12.29 TFLOPS FP32, and 24.58 TFLOPS FP16 at a 2:1 ratio. In the available Geekbench OpenCL test, the MI25 scores 68562, placing it at the 92nd percentile of all GPUs.
How It Compares
Against the Intel Arc A770, the MI25 scores 68562 while the Arc A770 has an average score of 68809. The deltaPct of -0.4 means the MI25 is essentially at parity, trailing by less than a percentage point. This is the closest rival in the data.
Against the AMD Radeon Pro WX 8200, the MI25 is 1.2% behind. The WX 8200 averages 69408, so the MI25 needs a small margin to match that result, but the gap remains narrow.
Against the NVIDIA Quadro P6000, the MI25 is ahead by 1.8%. The P6000 averages 67320, placing the MI25 above it in the Geekbench OpenCL ranking.
Against the AMD Radeon Pro Vega 56, the MI25 is 2.2% ahead. The Vega 56 averages 67097, making it the lowest-scoring rival listed, while the MI25 sits above it in both raw score and relative position.
Ray Tracing and Feature Set
The specification data lists no RT cores and no tensor cores for the MI25. Because both counts are null, there is no dedicated ray tracing or tensor hardware to report. The card instead relies on GCN 5.0 compute resources: 4096 shading units, 256 TMUs, and 64 ROPs, with 16GB HBM2 memory and a 2048-bit bus.
In terms of API support, the MI25 supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.3. These are the only API versions listed in the fact pack. The board also uses a PCIe 3.0 x16 interface.
The feature set is completed by its compute-oriented design: the card has no display outputs. This is not a rendering card with monitor connections, but an accelerator with high FP32 and FP16 throughput, backed by the Vega 10 memory subsystem.
Who Should Consider It
The MI25 is a compute-only accelerator. Because the fact pack lists no display outputs, it cannot directly drive a monitor at any resolution, so users building a workstation with a display need a separate graphics solution.
For Geekbench OpenCL workloads, the MI25 scores 68562 and holds the 92nd percentile of all GPUs. That means it ranks above the majority of GPUs in the database on this specific compute test. Its nearest rivals are close, with the largest delta among the listed rivals at 2.2%, so users should expect similar performance to those cards in OpenCL compute tasks.
The 16GB HBM2 frame buffer and 436.2 GB/s bandwidth are well suited to workloads that need large working sets near the GPU. The 12.29 TFLOPS FP32 rate covers standard precision compute, while the 24.58 TFLOPS FP16 rate offers double the FP32 throughput, which can benefit mixed-precision pipelines.
The card is end-of-life, so it is not a current production part. It should be considered by users with compatible GCN 5.0 compute environments and a need for high bandwidth memory in a dual-slot, 300W envelope.
