Can I Run Gemma 4 E4B on NVIDIA GeForce RTX 5070?
Written by Jakub Rusinowski · Last updated July 12, 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 5070 has 12 GB, leaving about 5.6 GB of headroom, at roughly 90 tok/s (estimated).

Gemma 4 E4B on the NVIDIA GeForce RTX 5070: 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 12 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 5070: 8K 6.4 GB · 32K 9.9 GB · 125K 23.1 GB ✗. Past 125K it no longer fits 12 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.
