This setup is broadly balanced for this model.
Very little memory headroom
You can run the model, but there is not much room left for longer context, bigger batches, extra apps, or future model updates.
Buy headroom, not only minimum fit
A slightly larger memory tier gives you safer context growth and makes the recommendation more future-proof.

Inference speed
Estimated decode speed (tokens/sec) for WizardMath 7B at Q4_K_M across popular GPUs and Apple Silicon, using the fastest local runtime per device. Fastest is RTX 5090 32GB at ~98 tok/s. Speed is memory-bandwidth bound, so cards that fit the whole model in VRAM run far faster than ones that offload to system RAM.

Yes, Radeon RX 7700S 8GB can run WizardMath 7B with a A grade (Runs with offload). Expected decode speed: 42.8 tok/s.
WizardMath 7B (7B parameters) requires approximately 7.9 GB of memory with Q4_K_M quantization.
The recommended quantization for WizardMath 7B is Q4_K_M, which balances quality and memory efficiency.
On Radeon RX 7700S 8GB, WizardMath 7B achieves approximately 42.8 tokens per second decode speed with a time-to-first-token of 4526ms using Q4_K_M quantization.
For coding workloads, WizardMath 7B on Radeon RX 7700S 8GB receives a A grade with 42.8 tok/s and 4K context.
On Radeon RX 7700S 8GB, WizardMath 7B can safely use up to 4K tokens of context. The model's official context limit is 4K, but available memory constrains the safe maximum.
Buy headroom, not only minimum fit. A slightly larger memory tier gives you safer context growth and makes the recommendation more future-proof.
