Articles & guides.
Comparison guides, leaderboards, and how-tos for renting cloud GPUs. Each article uses live pricing data from the RentGPU catalog.
Comparison
48 GB GPUs compared: RTX A6000 vs L40S vs RTX 6000 Ada
RTX A6000, A40, L40, L40S and RTX 6000 Ada compared for 70B at 4-bit and 30B at FP8: Ampere vs Ada, FP8 support, speed estimates and live prices.
GPU marketplaces vs managed clouds: Vast.ai, io.net, Clore vs Lambda
Why marketplace GPUs from Vast.ai, io.net and Clore undercut Lambda and RunPod, what you trade in reliability and security, and how to vet a host.
RTX 5090 vs RTX 4090 for running LLMs
32 GB GDDR7 vs 24 GB GDDR6X: what fits on each card, how bandwidth sets token speed, cost per token at live prices, and when a 3090 is still the pick.
H100 vs H200 vs B200 for LLM inference
Memory, bandwidth and cost per token for the H100, H200 and B200: when extra HBM avoids sharding, and which card to rent for your model size.
Cheapest way to run a 70B model: API, rented GPU, or your own
Hosted API, rented GPU or owned hardware for a 70B LLM? Cost math for occasional, internal-tool and production workloads, with live prices and breakeven.
RTX 4090 vs H100: Cost per FLOP for AI training
Live rental prices and spec-sheet tensor throughput give the real cost per petaflop-hour on each card — and why memory and interconnect change the answer.
Guide
Spot vs on-demand GPU rental: when interruptible is worth it
How spot, preemptible and bid-tier GPU pricing works, which AI workloads survive interruption, and the checkpoint math that shows when spot really saves.
How much VRAM do you need to run an LLM?
Estimate LLM VRAM from weights, KV cache and overhead: per-precision sizes for 8B to 671B models, GQA explained, and a worked 70B INT4 32k-context example.
