Frequently Asked Questions: RTX Pro 6000 vs RTX 4090
The main differences are VRAM (96 GB vs 24 GB), FP16 throughput (126 vs 82.58 TFLOPS), architecture (Blackwell vs Ada Lovelace). The RTX Pro 6000 uses the Blackwell architecture while the RTX 4090 is based on Ada Lovelace, giving each GPU different generational capabilities.
The RTX Pro 6000 is generally better for large language model training due to its higher throughput and 96 GB of VRAM, which allows fitting larger models or larger batch sizes in a single pass. For smaller models or fine-tuning tasks where cost matters more, both GPUs can be effective.
On Shadeform, the RTX 4090 is available from $0.60/hr. The RTX Pro 6000 starts from $1.25/hr. Prices vary by provider, region, and contract length. Reserved commitments can reduce hourly costs significantly compared to on-demand pricing.
The RTX Pro 6000 has more VRAM at 96 GB, compared to 24 GB on the RTX 4090. Higher VRAM allows you to run larger models without quantization, use longer context windows, and process larger batch sizes — all of which improve throughput and reduce latency for memory-bound workloads.
Based on TFLOPS per dollar, the RTX 4090 offers better raw compute value at current Shadeform on-demand rates. However, the best choice depends on your specific workload — if you need the extra VRAM or throughput of the RTX Pro 6000, paying the premium may be justified by faster job completion and lower total cost.
The RTX Pro 6000 is currently available across 7 cloud providers on Shadeform's network, compared to 3 for the RTX 4090. Shadeform lets you deploy either GPU across all available providers from a single platform, so you can always find available capacity without manually checking each cloud.
Mixing different GPU types in a single training cluster is generally not recommended, as it creates performance bottlenecks where faster GPUs wait for slower ones. For best results, use a homogeneous cluster of either RTX Pro 6000 or RTX 4090. Shadeform supports on-demand clusters of up to 64 GPUs of the same type with no commitment required.
