GeForce RTX 3090 Ti 24 GB vs NVIDIA Tesla P40 24 GB
GeForce RTX 3090 Ti has 24 GB memory, 1,008 GB/s bandwidth, 450 W nominal power; Tesla P40 has 24 GB memory, 346 GB/s bandwidth, 250 W nominal power. Compare model compatibility, like-for-like tokens/sec and ownership cost below.
Verdict
- throughputNo valid like-for-like performance comparison is available. The practical configurations below differ in quantization, runtime, context, settings, or evidence type, so their speed difference must not be attributed to hardware alone.
- capacityBoth machines run all 8 compared models in their best practical configurations. Compare their quantizations and evidence labels before treating any throughput difference as a hardware result.
- costAt 8 hours a day, the NVIDIA Tesla P40 24 GB has approximately 44% lower total monthly cost ($1 against $3), for a C corporation in United States (federal).
- powerThe GeForce RTX 3090 Ti 24 GB draws 450 W under load against 250 W for the NVIDIA Tesla P40 24 GB — a 1.8× difference that shows up in the electricity line and in how loud and hot the room gets.
- evidenceThere are no comparable throughput rows, so this page makes no hardware-speed ranking. Practical deployment figures remain useful for fit planning but answer a different question.
- recommendationThroughput is close enough to be a wash, so this comes down to cost and capacity: the NVIDIA Tesla P40 24 GB is cheaper to own, and capacity differences above decide which models you can run at all.
Every statement above is generated from the calculations on this page by fixed rules — no prose is written for individual comparisons. If the numbers change, the verdict changes with them.

Hardware deltas are calculated only when quantization, runtime, exact context, execution/decode mode and relevant inference settings match. Measured and estimated results are never compared to each other. A difference under 10% is reported as a tie.

This is a deployment comparison: each machine uses its own recommended configuration. Different quantizations can change speed and quality, so these figures are not raw hardware benchmarks.

Purchase prices are localized inputs in USD: tax/VAT excluded for GeForce RTX 3090 Ti 24 GB and tax/VAT excluded for NVIDIA Tesla P40 24 GB. Net cash and monthly economic cost then apply the selected United States (federal) / C corporation tax treatment. Tax assumptions last verified 2026-09-07. Federal planning estimate only, not tax advice. State and local income tax, sales/use tax and incentives are excluded. It assumes 100% business use, a Section 179 election, enough business income to use it, and that the full annual limit remains available.
