V100 32GB vs RTX 4500 Ada
Both run on the same nodes, the same templates and the same tiers here — so the choice comes down to memory, bandwidth and price. Every figure below is from the catalogue or the vendor datasheet.

What actually separates them.
Four differences that change a decision, computed from the numbers rather than asserted.
Bigger models fit on the V100
32 GB against 24 GB. At FP16 that is about 12B parameters on one GPU, against 9B.
The V100 costs 33% less per hour
$0.06 against $0.09 on spot — $3.00 of difference over 100 GPU-hours.
Token generation is faster on the V100
900 GB/s against 432 GB/s. Inference reads the whole model from memory for every token, so bandwidth, not FLOPS, usually sets the ceiling.
More memory per dollar on the V100
533 GB per dollar per hour against 267 GB. The usual tie-breaker when both cards fit the job.
Every figure we hold on both cards.
A row is marked only when both values exist and one is genuinely better. V100 leads on 7 rows, RTX 4500 Ada on 4.

Specifications come from each vendor's datasheet — linked on the V100 page and the RTX 4500 Ada page. Prices are ours, per GPU-hour, billed per minute.
The same models, on one GPU of each.
Weights only, with 20% of the memory kept free for activations and the KV cache. A cross means one GPU is not enough — the model page has the multi-GPU arithmetic.

Take the V100 when…
- Fine-tuning small models — LoRA on 7B–13B models, and full fine-tuning below 3B.
- Image and video generation — Diffusion pipelines run entirely in memory at this capacity.
- Multi-GPU jobs over NVLink — GPU-to-GPU traffic stays off the PCIe bus, which is what makes tensor and pipeline parallelism worth it.
Take the RTX 4500 Ada when…
- Fine-tuning small models — LoRA on 7B–13B models, and full fine-tuning below 3B.
- Image and video generation — Diffusion pipelines run entirely in memory at this capacity.
- Anything that can checkpoint — On the spot tier this model is 40% below its own on-demand price, with a 2-minute notice before a reclaim.
V100 or RTX 4500 Ada?
Which is cheaper, the V100 or the RTX 4500 Ada?
The V100 32GB, at $0.06 per GPU-hour on spot against $0.09 — 33% less. On-demand: $0.09 against $0.15.
Which one should I take for inference?
Take the one that holds the model with room for the KV cache, then the one with more memory bandwidth. Here that is the V100 on capacity (32 GB) and the V100 on bandwidth.
Can I run both on the same job?
Not inside one instance — a node holds GPUs of a single model. You can run two instances in parallel, on the same persistent volume in turn, or split the work: a big card for the model that needs capacity, a cheap one for the parts that do not.
