Can I Run Gemma 4 E4B on NVIDIA GeForce RTX 3070 Ti?
Written by Jakub Rusinowski · Last updated September 29, 2026
Yes. Gemma 4 E4B needs 6.4 GB at 8K context (4.5 GB weights + 1.9 GB KV cache/overhead) at Q4 (QAT) and the NVIDIA GeForce RTX 3070 Ti has 8 GB, leaving about 1.6 GB of headroom, at roughly 64 tok/s (estimated).

Gemma 4 E4B on the NVIDIA GeForce RTX 3070 Ti: VRAM by quantization

Assumes an 8K-token context with an f16 KV cache, on an estimated architecture — this model publishes no config we can read. A longer window needs more; a quantized KV cache needs less. “Max context” is the largest window that still fits in 8 GB. Figures are estimates from parameter count, quantization and memory bandwidth — the analyzer lets you tune KV-cache quant and context.
Context costs VRAM too. At Q4 (QAT) on the NVIDIA GeForce RTX 3070 Ti: 8K 6.4 GB · 32K 9.9 GB ✗ · 125K 23.1 GB ✗. Past 32K it no longer fits 8 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
What to do next
Nothing to change — run it at Q4 (QAT). If you want more capability, check whether the next size up also fits.
No compatible GPU? Gemma 4 on 8 GB of system RAM, CPU only: runs, but it is tight.
