The non-XT Radeon RX 5500 officially has 4 GB GDDR6 and a 150 W board specification.
The non-XT Radeon RX 5500 officially has 4 GB GDDR6 and a 150 W board specification. It is a separate configuration, not an abbreviation covering all 4 GB or 8 GB RX 5500 XT variants.
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 |
|---|---|---|
| 4 GB | 4 GB GDDR6 | 150 W |
Establish the LLM software path
Radeon RX 5500 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
The practical case is an equipment record containing only “5500” while model settings assume 8 GB. Establish actual capacity and complete device identity first, then retain the original profile as unverified. For 4 GB, investigate a small fixed checkpoint or explicit partial placement instead of describing system RAM as expanded GPU memory. If a larger model loads with most components on the CPU, record placement and required RAM separately. An error-free startup does not make the previous 8 GB profile applicable unchanged. Correcting inventory is part of technical acceptance here because an incorrect capacity changes every later choice of files, context, and expected GPU participation. The complete name should therefore survive into the machine profile rather than disappear after the initial inspection.
Validate Blender Cycles separately
RDNA 1 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.
Preserve the exact scene resource set and complete a frame on the actual 4 GB. A preset from a higher-capacity XT is a new hypothesis, not a validated configuration.
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.
Keep RX 5500, 4 GB, and the 150 W board specification explicit. Do not borrow board power from RX 5500 XT; the shared name fragment does not combine these products.
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.
