RTX 4090 vs V100: Which Should You Choose?
The RTX 4090 offers 24 GB of VRAM — 1.5× the 16 GB on the V100 — making it better suited for large model workloads that require holding more parameters in GPU memory. On FP16 throughput, the RTX 4090 delivers 82.58 TFLOPS versus 28.26 TFLOPS on the V100 — 3× faster for mixed-precision training and inference. Memory bandwidth favors the V100 at 0.90 TB/s compared to 0.00 TB/s on the RTX 4090, which directly impacts inference latency for memory-bandwidth-bound models. Architecturally, the RTX 4090 is built on Ada Lovelace while the V100 uses Volta, reflecting different generational capabilities and optimizations. On Shadeform, the V100 starts from $0.39/hr versus $0.60/hr for the RTX 4090 — 54% more expensive — reflecting the performance premium.

Frequently Asked Questions: RTX 4090 vs V100
The main differences are VRAM (24 GB vs 16 GB), FP16 throughput (82.58 vs 28.26 TFLOPS), architecture (Ada Lovelace vs Volta). The RTX 4090 uses the Ada Lovelace architecture while the V100 is based on Volta, giving each GPU different generational capabilities.
The RTX 4090 is generally better for large language model training due to its higher throughput and 24 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 V100 is available from $0.39/hr. The RTX 4090 starts from $0.60/hr. Prices vary by provider, region, and contract length. Reserved commitments can reduce hourly costs significantly compared to on-demand pricing.
The RTX 4090 has more VRAM at 24 GB, compared to 16 GB on the V100. 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 V100, paying the premium may be justified by faster job completion and lower total cost.
The RTX 4090 is currently available across 3 cloud providers on Shadeform's network, compared to 3 for the V100. 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 4090 or V100. Shadeform supports on-demand clusters of up to 64 GPUs of the same type with no commitment required.
