Yes. Gemma 4 E4B needs 4.5 GB at Q4 (QAT) and the AMD Radeon RX 7900 XTX has 24 GB, leaving about 19.5 GB of headroom, at roughly 86 tok/s (estimated) with room for up to 64K of context.

Assumes a 4K-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 24 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 AMD Radeon RX 7900 XTX: 8K 6.4 GB · 32K 9.9 GB · 125K 23.1 GB. Every window this model publishes still fits 24 GB.
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.
