Frequently Asked Questions
Which GPU is better for AI training: T4G or Instinct MI300X?
For AI training, the key factors are VRAM size, memory bandwidth, and tensor core performance. The T4G offers 16GB of GDDR6 memory with 320 GB/s bandwidth, while the Instinct MI300X provides 192GB of HBM3 with 5.3 TB/s bandwidth. For larger models, the Instinct MI300X's higher VRAM capacity gives it an advantage.
What is the price difference between T4G and Instinct MI300X in the cloud?
Cloud GPU rental prices vary by provider and region. Based on our data, T4G starts at $0.23/hour while Instinct MI300X starts at $0.95/hour. This represents a 76% price difference.
Can I use Instinct MI300X instead of T4G for my workload?
It depends on your specific requirements. If your model fits within 192GB of VRAM and you don't need the additional throughput of the T4G, the Instinct MI300X can be a cost-effective alternative. However, for workloads requiring maximum memory capacity or multi-GPU scaling, the T4G's architecture may be essential.
