Can I Run Yi 1.5 34B Chat on AMD Radeon RX 9060 XT 8GB?
Written by Jakub Rusinowski · Last updated July 12, 2026
No. Yi 1.5 34B Chat needs 23.6 GB at 8K context (20.8 GB weights + 2.8 GB KV cache/overhead) at Q4_K_M and the AMD Radeon RX 9060 XT 8GB has only 8 GB. No quantization we publish closes a gap that size.

Yi 1.5 34B Chat on the AMD Radeon RX 9060 XT 8GB: VRAM by quantization

Assumes an 8K-token context with an f16 KV cache. 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_K_M on the AMD Radeon RX 9060 XT 8GB: 8K 23.6 GB ✗ · 31K 29.4 GB ✗. Past 8K 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
Either step down to a smaller size in this family, or move to a NVIDIA GeForce RTX 5090 Laptop GPU (24 GB), the card with the least memory we track that holds it.
No compatible GPU? Yi 1.5 34B Chat on 32 GB of system RAM, CPU only: runs comfortably.
Yi 1.5 34B Chat needs ~24 GB but this GPU has 8 GB. Rent a RTX 4090 (24 GB)-class GPU by the hour instead of buying one:
