How the AMD Radeon RX 6750 XT compares with similar cards

Compared with the AMD Radeon RX 7700 XT, the AMD Radeon RX 6750 XT has the same 12 GB of VRAM, so the same models fit fully on the GPU; the same 432 GB/s of memory bandwidth, so the same estimated ~72 tokens/s on an 8B model in Q4; a higher board power (250 vs 245 W) and an older architecture (RDNA 2 vs RDNA 3). For local LLMs the two generate tokens at the same speed: the difference comes down to GPU compute, which mainly affects prompt processing. Side-by-side comparison
Compared with the AMD Radeon RX 6700 XT, the AMD Radeon RX 6750 XT has the same 12 GB of VRAM, so the same models fit fully on the GPU; about 12% faster token generation (~72 vs ~64 tokens/s on an 8B model in Q4, from 432 vs 384 GB/s) and a higher board power (250 vs 230 W). Side-by-side comparison
Compared with the Intel Arc B580, the AMD Radeon RX 6750 XT has the same 12 GB of VRAM, so the same models fit fully on the GPU; about 5% slower token generation (~72 vs ~76 tokens/s on an 8B model in Q4, from 432 vs 456 GB/s); a higher board power (250 vs 190 W) and a different architecture (RDNA 2 vs Battlemage). Side-by-side comparison

Token speeds here are a conservative estimate (memory bandwidth ÷ 6, for an 8B model in Q4 that reads about 5 GB of weights per token, plus overhead); prompt processing depends on GPU compute instead.
