What GPU Do You Need for SmolLM2-135M?, tok/s by GPU
Efficiency: tok/s per 100W drawn
Power is the average pulled during the run, sampled at 1Hz. The fastest card is often not the one here, and for anything left running this is the number that shows up on the bill.
Value: tok/s per $1,000 of MSRP
Launch price, not street price, so it ages. A speed leaderboard always crowns the most expensive card; this is the counterweight.

Cheapest hourly rate we track on RunPod and Vast.ai, divided by the measured speed. Startup time and storage are extra.
Speed tiers for SmolLM2-135M. 30+ tok/s: 11 (RTX PRO 6000 Blackwell Workstation Edition, L40S, H200). 30 tok/s is roughly where replies outpace reading.
Reading your prompt. Before SmolLM2-135M writes anything it reads the input: 59353.3 tok/s on the RTX PRO 6000 Blackwell Workstation Edition (0.1s for a 4,000-token prompt), 10221.7 on the T4 (0.4s). Long documents and big code files feel this number more than the generation speed.
VRAM for SmolLM2-135M. Measured peak 0.8GB, so 8GB is the smallest common card size; smallest card it ran on: T4 (16GB). With long context: Q4_K_M 1GB (tested), Q2_K 1GB, Q3_K_M 1GB, Q5_K_M 1GB, Q6_K 1GB.
Power on SmolLM2-135M. Most efficient: L4, 36W, 15.3 Wh per 1M generated tokens. Hungriest: B200, 252W, 85.9 Wh.
Fastest on SmolLM2-135M: NVIDIA RTX PRO 6000 Blackwell Workstation Edition, 1252.8 tok/s. Cheapest to rent per job: NVIDIA T4, $0.091 per 1M generated tokens.
llama.cpp llama-bench at Q4_K_M, 512-token prompt and 128 generated tokens, three runs after a warmup, full GPU offload, with power and VRAM sampled throughout. Token generation is memory-bandwidth-bound, so the ranking tracks bandwidth closely, which makes it a fair guide to cards we haven't run yet.
