AMD Instinct MI325X vs AMD Radeon PRO W7500 Comparison

Head-to-Head Benchmarks

The database records no head-to-head benchmark comparisons between the AMD Instinct MI325X and the AMD Radeon PRO W7500. The MI325X has no benchmark scores, no average score, and no nearest rivals in the database. The W7500 has nine recorded benchmark scores across compute and graphics workloads, but none of these can be compared directly to the MI325X because the MI325X has zero recorded benchmarks.

The W7500's recorded data shows a Geekbench OpenCL score of 58,213 and a Geekbench Vulkan score of 68,634. Its Passmark scores include DirectX 9 at 200, DirectX 10 at 65, DirectX 11 at 125, DirectX 12 at 46, G2D at 1,174, G3D at 13,368, and GPU Compute at 5,910. The average benchmark score for the W7500 is 16,415, placing it in the 59th percentile of all GPUs in the database.

Since the MI325X has no benchmark entries, its percentile of 50 is a placeholder value rather than a measured position. The absence of data means the head-to-head comparison cannot be quantified. The W7500's nearest rivals in the database are the NVIDIA RTX PRO 6000 Blackwell with an average score of 16,408 (0% delta), the AMD Radeon RX 5700 XT with 16,361 (0.3% delta), the AMD Radeon Pro 5600M with 16,351 (0.4% delta), and the NVIDIA GeForce RTX 5090 D V2 with 16,504 (-0.5% delta). These deltas are all within one percent, indicating the W7500 sits in a tightly grouped performance cluster.

The MI325X's lack of benchmark scores means its performance cannot be positioned relative to the W7500 or any other GPU. The data does not support any quantitative comparison, only a qualitative description of the two products' specifications.

Architecture Differences

The MI325X uses the Aqua Vanjaram chip built on CDNA 3.0 architecture, fabricated on a 5 nm process at TSMC. It contains 153,000 million transistors on a 1,017 mm² die, producing a transistor density of 150.4 million per mm². The chip is part of the Instinct (MIx) generation, replacing the Radeon Instinct lineup.

The W7500 uses the Navi 33 chip built on RDNA 3.0 architecture, with the codename Hotpink Bonefish. It is fabricated on a 6 nm process at TSMC, contains 13,300 million transistors on a 204 mm² die, and has a transistor density of 65.2 million per mm². It belongs to the Radeon Pro Navi (Navi III Series) generation and succeeds the Radeon Pro Vega.

The MI325X uses HBM3e memory with 256 GB capacity, an 8,192-bit bus, and 6.14 TB/s bandwidth. The W7500 uses GDDR6 memory with 8 GB capacity, a 128-bit bus, and 256.0 GB/s bandwidth. The memory clock on the MI325X is 1500 MHz with 6 Gbps effective, while the W7500 runs at 2000 MHz with 16 Gbps effective.

The MI325X has 19,456 shading units, 1,216 texture mapping units, and no ROPs, resulting in a pixel rate of 0 MPixel/s and a texture rate of 2,553.6 GTexel/s. Its FP32 performance is 81.72 TFLOPS, and FP16 is 81.72 TFLOPS at a 1:1 ratio. The W7500 has 1,792 shading units, 112 TMUs, 64 ROPs, and 28 ray tracing cores. Its pixel rate is 108.8 GPixel/s, texture rate is 190.4 GTexel/s, FP32 is 12.19 TFLOPS, and FP16 is 24.37 TFLOPS at a 2:1 ratio.

The MI325X has no display outputs, no API support (DirectX, OpenGL, Vulkan all listed as N/A), and uses an OAM Module slot width with no power connectors and a suggested power supply of 1,400 W. The W7500 has 4x DisplayPort 2.1 outputs, supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, uses a single-slot form factor, has no power connectors, and requires a 250 W suggested power supply.

The MI325X has a base clock of 1,000 MHz and boost clock of 2,100 MHz. The W7500 has a base clock of 1,500 MHz and boost clock of 1,700 MHz. The MI325X uses a PCIe 5.0 x16 interface, while the W7500 uses PCIe 4.0 x8.

Where Each One Wins

The W7500 is the only product with recorded benchmark data, so it holds wins in all measurable categories by default. Its Geekbench scores of 58,213 in OpenCL and 68,634 in Vulkan indicate strong compute and graphics API performance. Its Passmark G3D score of 13,368 and GPU Compute score of 5,910 show balanced rasterization and compute capabilities.

The W7500's API support is a clear advantage for workstation graphics workloads. DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 support enable professional visualization software, CAD applications, and content creation tools. The 4x DisplayPort 2.1 outputs allow multi-monitor setups. The 28 ray tracing cores provide hardware acceleration for ray-traced rendering in supported applications.

The MI325X wins on raw specification counts. Its FP32 throughput of 81.72 TFLOPS is substantially higher than the W7500's 12.19 TFLOPS. The memory system is another decisive win: 256 GB of HBM3e with 6.14 TB/s bandwidth versus 8 GB of GDDR6 with 256.0 GB/s. The 8,192-bit bus width on the MI325X dwarfs the 128-bit bus on the W7500. The 19,456 shading units versus 1,792 represent a 10.9x difference, and the 1,216 TMUs versus 112 represent a 10.9x difference.

The MI325X has no display outputs, making it unsuitable for any workflow requiring visual output. The W7500's 4x DisplayPort 2.1 outputs and full API stack make it a complete workstation graphics solution. The MI325X has no API support, which means no DirectX, OpenGL, or Vulkan applications can run on it directly. Its purpose is compute acceleration, not graphics rendering.

Power requirements show a similar split. The MI325X has a TDP of 1,000 W and a suggested power supply of 1,400 W, while the W7500 has a TDP of 70 W and a suggested power supply of 250 W. The MI325X requires an OAM Module slot, while the W7500 fits in a standard single-slot configuration.

The Verdict

The data shows two products designed for entirely different purposes. The MI325X is a compute accelerator with massive memory capacity and throughput, no display outputs, and no graphics API support. The W7500 is a professional workstation GPU with display outputs, full API compatibility, and modest compute specifications.

For compute-heavy workloads such as large-scale machine learning, scientific simulation, or data center inference, the MI325X's specification sheet indicates far greater capability. Its 256 GB of HBM3e memory and 6.14 TB/s bandwidth allow processing of datasets that would exceed the W7500's 8 GB GDDR6 capacity many times over. The FP32 throughput of 81.72 TFLOPS is roughly 6.7x the W7500's 12.19 TFLOPS.

For workstation graphics, professional visualization, CAD, and content creation, the W7500 is the only viable option between the two. Its 4x DisplayPort 2.1 outputs, DirectX 12 Ultimate support, OpenGL 4.6, and Vulkan 1.4 enable standard workstation workflows. The MI325X cannot output video and supports no graphics APIs, making it unsuitable for these tasks.

The production status field shows the W7500 as Active, while the MI325X has no production status recorded. The W7500 was released on 2023-08-02, and the MI325X was released on 2024-10-09. The W7500 has a launch MSRP of 429 USD.
