Frequently Asked Questions
Which GPU is better for AI training: RTX 5090 or RTX 4090?
For AI training, the key factors are VRAM size, memory bandwidth, and tensor core performance. The RTX 5090 offers 32GB of GDDR7 memory with 1.79 TB/s bandwidth, while the RTX 4090 provides 24GB of GDDR6X with 1.01 TB/s bandwidth. For larger models, the RTX 5090's higher VRAM capacity gives it an advantage.
What is the price difference between RTX 5090 and RTX 4090 in the cloud?
Cloud GPU rental prices vary by provider and region. Based on our data, RTX 5090 starts at $0.16/hour while RTX 4090 starts at $0.20/hour. This represents a 20% price difference.
Can I use RTX 4090 instead of RTX 5090 for my workload?
It depends on your specific requirements. If your model fits within 24GB of VRAM and you don't need the additional throughput of the RTX 5090, the RTX 4090 can be a cost-effective alternative. However, for workloads requiring maximum memory capacity or multi-GPU scaling, the RTX 5090's architecture may be essential.
