The available benchmark figures show how an 8.4 GB Qwen3.8-27B quantization compares with its BF16 base model—not how it performs against Claude. ISTA-DASLab reports a LiveCodeBench v6 score of 76.57 for its IQ2_XS build and 85.71 for the BF16 model. Those are publisher-reported results, not a head-to-head Qwen-versus-Claude test.
What does “Qwen 8.4 GB” mean?
ISTA-DASLab lists an IQ2_XS quantization of Qwen3.8-27B at 8.4 GB in its model repository. It is a compressed version of the Qwen3.8-27B model, not the BF16 base model. The file size describes the listed model artifact; it does not by itself establish how much memory a particular inference setup needs.
What coding benchmark results are reported?
On LiveCodeBench v6, ISTA-DASLab reports 76.57 for the 8.4 GB IQ2_XS quantization and 85.71 for the BF16 base model. The repository presents these as results for the base model and its quantizations, not as a comparison with Claude.

These figures are the repository publisher’s reported evaluations, not an independent replication. The score difference describes the two listed Qwen variants on this benchmark; it does not establish how either would fare across every coding task or workflow.
#1 Best Overall
Was the 8.4 GB Qwen build tested against Claude?
The cited model-card results do not include Claude. Geeky Gadgets and Skalablog also report that the 8.4 GB build was not directly tested against Claude (Geeky Gadgets; Skalablog). That supports a narrow conclusion: the comparison evidence cited here does not establish a Qwen-versus-Claude winner. It does not prove that no private or unpublished comparison exists.
A meaningful head-to-head test would need to identify the exact Claude version and Qwen quantization, use the same tasks and prompts, and disclose tool access, inference settings, compute or token budgets, scoring method, and test date. Without those controls and a Claude result, the LiveCodeBench figures cannot answer whether this Qwen build matches Claude.

Do not treat 8.4 GB as a guaranteed VRAM requirement—or as proof that the model will fit on a GPU with exactly that much memory. Runtime overhead, context length, and other settings affect memory use. The sources cited here do not establish a universal minimum GPU specification.

Pick the symptom - the matching free tool is one click away.
Before choosing hardware, check the runtime’s requirements for the exact model file and account for memory used by the context and runtime. If you plan to load vision components, verify whether they require additional memory. The published file size alone cannot settle whether a particular machine will run the model successfully.
Quick Recap
Rank #3
How to use these results when choosing a coding assistant
- If you want a local model: the 8.4 GB listing identifies a compact Qwen quantization to investigate, but check your intended runtime and workload rather than assuming it fits your hardware.
- If you want to compare coding quality with Claude: these scores are not enough to make that choice. Look for results from a controlled, direct test using the versions and workflow you care about.
- If you are weighing the quantized model against its base: ISTA-DASLab’s reported LiveCodeBench v6 figures favor the BF16 base model in this table, while the quantized entry has the listed 8.4 GB file size. The figures do not quantify the trade-off for your own tasks or setup.
