Radeon RX 6750 GRE has official 10 GB and 12 GB GDDR6 variants.
Radeon RX 6750 GRE has official 10 GB and 12 GB GDDR6 variants. Compare them explicitly: official tables disagree about the 12 GB board-power value, which remains unverified here.
Official variants and the memory boundary
The table follows AMD materials for this model. 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 |
|---|---|---|
| 10 GB | 10 GB GDDR6 | 170 W |
| 12 GB | 12 GB GDDR6 | Not verified |
Establish the LLM software path
Radeon RX 6750 GRE is absent from the checked ROCm Core SDK 10.1.0 GPU list. 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 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
A practical example is preparing two profiles for machines containing different GRE variants. Preserve the exact 10 GB or 12 GB identity on each board first: these are documented configurations, not an arbitrary memory-size switch on one card. The official pocket guide specifies 170 W for the 10 GB model. For the 12 GB version, choosing one number mechanically from conflicting tables cannot establish the specification of every actual board. Use the specific board documentation and leave the field unresolved until it is checked. Preserve the same model and input during software tests, then compare actual placement and validated context. Nominal capacity differences alone determine neither parallel-request capacity nor permission to transfer one configuration unchanged onto the other.
Validate Blender Cycles separately
RDNA 2 meets the HIP hardware floor in the Blender Cycles 5.2 LTS manual: RDNA 1 or newer. This renderer requirement is independent of ROCm LLM support; validate the actual driver, build, and scene on the intended machine.
Prepare identical scene resources and complete a frame on both variants. If one requires a simplified project, preserve that separately rather than treating it as the original comparison.
Preserve a machine-level acceptance record
The table gives AMD board-power specifications, not measured whole-computer consumption. Check the power supply, connectors, card dimensions, and airflow path for the actual system separately. Board power cannot establish inference speed.
The acceptance table needs distinct GRE 10 GB and GRE 12 GB entries. Unverified board power is a useful evidence limitation; do not substitute a neighboring variant specification or seller claim.
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.
