1st promptCold start — includes initialization
>Solve: If a train travels at 60 mph for 2.5 hours, how far does it go?
Let me work through this step by step. Given information: - Speed = 60 mph (miles per hour) - Time = 2.5 hours Formula: Distance = Speed x Time Calculation: Distance = 60 mph x 2.5 h = 150 miles The train travels 150 miles. Double-check: at 60 mph the train covers 60 miles each hour. In half an hour it covers 30 miles. So in 2.5 hours: 60 + 60 + 30 = 150 miles. Confirmed.
2nd promptWarm — model ready, no init overhead
>What if the train stops for 20 minutes halfway?
The stop doesn't change the total distance covered while moving, but it affects total trip time. Breakdown: - First half: 1.25 hours at 60 mph = 75 miles - Stop: 20 minutes (no distance) - Second half: 1.25 hours at 60 mph = 75 miles Total distance: 150 miles (same) Total time: 2.5 h + 0.33 h = 2.83 hours Average speed: 150 / 2.83 = 53 mph The distance stays the same but average speed drops to 53 mph because of the stop.

What limits this setup

It fits through host-memory offload, and offload is the main reason performance drops.

CPU or host-memory offload is active

About 10% of the working set spills out of accelerator memory, which usually hurts latency and sustained decode throughput.

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.

Best improvement path

Remove offload with more accelerator memory

Prioritize a GPU or unified-memory tier that fits the whole model natively. Removing offload usually helps more than small compute gains.

Buy headroom, not only minimum fit

A slightly larger memory tier gives you safer context growth and makes the recommendation more future-proof.

Increase host RAM if you keep offloading

This setup may need roughly 0.4 GB of extra host RAM just for the offloaded portion, before OS and other tools.

Frequently asked questions

Can RX 5600 XT 6GB run WizardMath 7B?

Yes, RX 5600 XT 6GB can run WizardMath 7B at Q3_K_S quantization (Very compromised (needs ~0.4 GB host RAM)). The recommended Q4_K_M requires 7.7 GB which exceeds available memory, but at Q3_K_S it needs only 6.9 GB. Expected decode speed: 24.5 tok/s.

How much VRAM does WizardMath 7B need?

WizardMath 7B (7B parameters) requires approximately 7.7 GB at Q4_K_M quantization. On RX 5600 XT 6GB, it fits at Q3_K_S using 6.9 GB.

What is the best quantization for WizardMath 7B?

The recommended quantization is Q4_K_M, but on RX 5600 XT 6GB the best fitting quantization is Q3_K_S, which uses 6.9 GB.

What speed will WizardMath 7B run at on RX 5600 XT 6GB?

On RX 5600 XT 6GB, WizardMath 7B achieves approximately 24.5 tokens per second decode speed with a time-to-first-token of 7896ms using Q3_K_S quantization.

Can RX 5600 XT 6GB run WizardMath 7B for coding?

For coding workloads, WizardMath 7B on RX 5600 XT 6GB receives a F grade with 16.6 tok/s and 4K context.

What context window can WizardMath 7B use on RX 5600 XT 6GB?

On RX 5600 XT 6GB, WizardMath 7B can safely use up to 4K tokens of context at Q3_K_S quantization. The model's official context limit is 4K, but available memory constrains the safe maximum.

What should I upgrade first if WizardMath 7B feels slow on RX 5600 XT 6GB?

Remove offload with more accelerator memory. Prioritize a GPU or unified-memory tier that fits the whole model natively. Removing offload usually helps more than small compute gains.
