Radeon PRO W7500 provides 8 GB GDDR6 with a 70 W board specification. Its hardware profile differs from W7600, and equal capacity establishes neither equal workloads nor software qualification.

## Official variants and the memory boundary

The table follows [AMD materials for this model](https://www.amd.com/en/products/graphics/workstations/radeon-pro/w7500.html). It describes dedicated device memory, not system RAM. A “not verified” entry preserves a source gap; a neighboring configuration cannot supply the missing specification.

| AMD variant | Dedicated memory | Board power |
|---|---|---|
| [8 GB](https://www.amd.com/en/products/graphics/workstations/radeon-pro/w7500.html) | 8 GB GDDR6 | 70 W |

## Establish the LLM software path

Radeon PRO W7500 is absent from the checked [ROCm Core SDK 10.1.0 GPU list](https://rocm.docs.amd.com/en/docs-10.1.0/about/release-notes.html). Support for a neighboring model cannot be transferred through a shared generation or a similar name. For a separate experiment, the [llama.cpp build documentation](https://raw.githubusercontent.com/ggml-org/llama.cpp/master/docs/build.md) describes a Vulkan backend. That route requires a suitable driver, detection of the actual device, and validation of the selected GGUF; Vulkan in a specification does not establish that every operation works. Save tensor-placement logs and compare output with a reference run before concluding that the GPU is actually involved. This is not a claim of current official ROCm support for this card.

## A practical scenario for this model

The scenario is assigning an existing card a role in a small workstation with constrained cooling. Begin with the actual W7500 specification and final chassis arrangement instead of transferring W7600 conditions. The 70 W value is not a system measurement and cannot establish workload-specific electricity savings. Prepare one small model fixture, test the experimental backend, and preserve actual GPU involvement. For mixed execution, record system RAM and the CPU portion separately; lower board power does not describe those components. Use another scene and log for the graphics scenario. The result can be several bounded workstation roles, each with its own validated environment, rather than one universal assertion about every possible task. This keeps the useful evidence attached to what was actually tested.

## Validate Blender Cycles separately

RDNA 3 meets the HIP hardware floor in the [Blender Cycles 5.2 LTS manual](https://docs.blender.org/manual/en/latest/render/cycles/gpu_rendering.html): RDNA 1 or newer. This renderer requirement is independent of ROCm LLM support; validate the actual driver, build, and scene on the intended machine.

Complete a frame with neighboring devices installed and the chassis closed. Changed cooling conditions require another hardware check even with identical scene files and driver.

## Preserve a machine-level acceptance record

[AMD defines a workstation deployment boundary](https://www.amd.com/en/products/graphics/workstations.html): the relevant W6000/W7000 products and AI PRO R9700 are not designed or validated for datacenter use. Rack installation alone does not change that qualification.

Keep 8 GB and 70 W attached to the correct measurement boundary in the W7500 record. Compare actual workloads, placement, and host state before interpreting observations from another workstation.

The acceptance artifact should connect board identity, software versions, model revision, and the workload actually exercised. After any of those changes, the old result describes its original run rather than establishing compatibility of the new configuration.
