NVIDIA RTX PRO 4500 Blackwell Server Edition is assessed here as an exact Blackwell board configuration. Its published 32 GB capacity is the starting point for a workload qualification, not a measured serving or rendering result.

## Exact model and memory variants

The server4500 has32 GB GDDR7 ECC, a 165 W published limit and passive single-slot FHFL construction. Its thermal solution depends on the host server.

| Variant | Memory | Published board power | Cooling / format |
|---|---|---|---|
| NVIDIA RTX PRO 4500 Blackwell Server Edition | 32 GB GDDR7 ECC | 165 W | Passive; 4.4 x 10.5 in; single-slot FHFL |

Specifications: [Official product/support documentation](https://www.nvidia.com/en-us/data-center/rtx-pro-4500-blackwell-server-edition/).

## LLM backend and memory budget

32 GB serving candidate whose software compatibility and supported isolation modes must be checked independently. Single-slot placement does not remove per-GPU runtime memory overhead.

Passing the architecture requirement does not certify every model, quantization kernel or prebuilt package.

Compatibility evidence: [vLLM GPU requirements](https://docs.vllm.ai/en/stable/getting_started/installation/gpu/).

## Cycles and batch rendering

Headless RTX render candidate for a server with adequate specified airflow; a passive card cannot establish cooling simply by fitting in a PCIe slot.

[Blender 5.2 LTS GPU rendering manual](https://docs.blender.org/manual/en/latest/render/cycles/gpu_rendering.html).

## Integration into a server or workstation

Map airflow through the installed card using the server vendor layout. Preserve the actual power and isolation configuration in the record. If a partitioned execution mode is tested, enumerate the visible device again before interpreting memory observations.

## A concrete qualification scenario

A compact server gains a single-slot GPU position but previously carried no accelerator. Validate the server airflow configuration before loading the selected model. Then execute a complete scene without borrowing results from the 200 W workstation4500. Keep full-GPU compute and any separately tested partition as different evidence rows. The useful artifact is a chassis-specific qualification, not a generic32 GB acceptance label.

## The evidence to retain

Keep an ordinary qualification record with the actual test outputs.

Identify the tested variant, software build and execution mode before entering observations. Leave unavailable measurements explicitly unknown.

The fields below separate published specifications from observed allocation and job completion, so a later operator can repeat the same case.

| Evidence field | What this profile must retain |
|---|---|
| Hardware identity | NVIDIA RTX PRO 4500 Blackwell Server Edition; physical variant and reported device identifier |
| Memory boundary | 32 GB published; observed free memory before and after loading |
| Inference artifact | Exact weights digest, quantization, context and offload configuration |
| Render artifact | Scene digest, renderer version, backend and denoising setting |
| System envelope | Driver, container/build digest, enclosure and cooling configuration |
| Completion evidence | Application exit status, output validity and observed memory failures |

Single-slot placement does not establish the required server airflow through the passive165 W card; retain the installed host configuration.
