gfx1101 workstation.

Form factor: PCIe add-in card; AMD product page lists 1×8-pin. AMD W7700 product page — GPU form factor PCIe add-in card. AMD does not list a 48 GB W7700 on the cited product page.

Cited support row: ROCm 10.1.0 compatibility matrix and Linux system requirements. We do not invent a support claim past that listing. AMD product page: PRO W7700.

HSA_OVERRIDE: Not needed on current 10.x.

What fits on this card (256K context)

Shopper verdict at 4K, then follow the pair page for 32K and full context. Q4 and up. No printed prices.

Workstation vs consumer

Built only from cited AMD product-page specs already on this sheet and the consumer /gpus pages. We do not invent a decode number or a street price.

1. 16 GB W7700 vs the 12 GB 7700 XT

   Same gfx1101 family. AMD cites 16 GB / 576 GB/s / 190 W TBP on the W7700 product page. The consumer 7700 XT directory row is 12 GB. Four GB more on the workstation sticker is not a measured decode claim.

2. W7700 vs the 16 GB 7800 XT

   Both are 16 GB gfx1101. The consumer 7800 XT product page cites 16 GB GDDR6, 624 GB/s, and 263 W typical board power. The W7700 cites 576 GB/s and 190 W TBP. Same VRAM class, different envelope. We do not invent a decode winner.

3. W7700 vs the measured R9700

   The R9700 is 32 GB gfx1201 and measured. The W7700 is 16 GB gfx1101, official on the cited ROCm row, and not measured on the local desktop. House 35B Q4–Q6 files do not sit in 16 GB on the calculator.

What fits in VRAM

llama.cpp, f16 KV, 1 GPU and 2 GPUs (split). Q6 / Q5 / Q4 rows are calculator estimates. UD-Q3_K_XL is a labeled estimate — not a local desktop run. Speed stays not yet measured on our R9700s. Tables cover house 35B, Flash, and every cited /models page. Change quant or context in the calculator.

House 35B Q3 cite: Hugging Face listing for Qwen3.6-35B-A3B-UD-Q3_K_XL.gguf (16.8 GB). Other Q3 rows use the calculator publisher-file note for that model.

System RAM

Minimum system RAM needed and RAM needed at full context for Qwen3.6-35B-A3B on llama.cpp at Q4_K_M, 32K selected and the model’s full context. Estimate until a first-party amdai-bench/run@1 card exists for this SKU. Rounded up to a real DIMM kit. Offload rows on the other /models tables repeat both labels.

llama.cpp-first stack

1. Step 1

   llama.cpp first

   Vulkan and ROCm/HIP are both in scope on this official gfx1101 workstation row. HIP when rocminfo lists gfx1101. Ollama and vLLM are secondary — not the house path for this card.

2. Step 2

   gfx1101 family package

   gfx1101 needs the gfx110x ROCm family package, same pin as the consumer 7800 XT / 7700 XT. Do not mix a gfx1100 (W7900 / W7800 / 7900 XTX) or gfx1201 (R9700) install. Re-check the cited matrix before you install.

3. Step 3

   16 GB workstation, not the 12 GB 7700 XT

   This sheet sizes the 16 GB W7700. AMD product page: 16 GB GDDR6, 576 GB/s, 190 W TBP. House 35B Q4–Q6 files do not fit this VRAM — expect RAM offload or a listed Q3 file, both estimates. Size the file on the calculator before you download.

4. Step 4

   Setup, then Stack Lab doctor

   First-run setup is Ubuntu. Open Stack Lab doctor for the gfx110x install family, then record an amdai-bench/run@1 card if you measure this SKU. House daily and Flash profiles are R9700 / local desktop — they do not apply here. Packages are not published yet.

Compare with…

Head-to-head pages use the same VRAM, bandwidth, and calculator fit already on the sheets. Q3 is a labeled estimate. No invented prices. PRO W7700 against the other published sheets:
