How the AMD Radeon RX 7700 XT compares with similar cards

Compared with the AMD Radeon RX 6750 XT, the AMD Radeon RX 7700 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 lower board power (245 vs 250 W) and a newer architecture (RDNA 3 vs RDNA 2). 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 7700 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); a higher board power (245 vs 230 W) and a newer architecture (RDNA 3 vs RDNA 2). Side-by-side comparison
Compared with the Intel Arc B580, the AMD Radeon RX 7700 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 (245 vs 190 W) and a different architecture (RDNA 3 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.

What is the VRAM and memory bandwidth of the AMD Radeon RX 7700 XT?

The AMD Radeon RX 7700 XT features 12 GB of VRAM and a memory bandwidth of 432 GB/s (GDDR6 192-bit). In local language model inference, VRAM determines which model sizes fit on the card, while memory bandwidth dictates how many tokens per second the GPU generates.

What is the best local AI model to run on a AMD Radeon RX 7700 XT?

The best overall model for the AMD Radeon RX 7700 XT is Qwen/Qwen3-8B-GGUF using the recommended Q8_0 quantization (9.47 GB total memory). With 12 GB of VRAM, this GPU typically runs a 14B model at Q5, comfortably at full GPU speed. Check our guide to the best LLMs for 12 GB VRAM for details.

Can the AMD Radeon RX 7700 XT run 14B models locally?

Yes. The AMD Radeon RX 7700 XT's 12 GB VRAM is the exact sweet spot for running 14B models (such as Qwen 2.5 Coder 14B) in Q4_K_M quantization (~9.2 GB footprint) with full 4,096-token context entirely in VRAM.

Does the AMD Radeon RX 7700 XT work with Ollama and LM Studio?

Yes. Under Linux, the AMD Radeon RX 7700 XT supports native ROCm acceleration in Ollama and llama.cpp. On Windows, Ollama and LM Studio utilize the Vulkan or DirectML backends to leverage the card's full 12 GB VRAM pool.
