RX 9070 XT vs RTX 5070 Ti for Local AI
The short answer
Both cards hold 16 GB of VRAM, so they sit in the same on-card model-size class. The split is bandwidth, stack, and price. The GeForce RTX 5070 Ti (product 17) uses GDDR7 at 896 GB/s on a 256-bit bus, 8,960 CUDA cores, 300 W, and a $749 launch MSRP. The Radeon RX 9070 XT (product 52) uses GDDR6 at 640 GB/s on a 256-bit bus, 4,096 stream processors, 304 W, and a $599 launch MSRP. Published bandwidth is 40% higher on the 5070 Ti. Street prices are NULL for both. We do not invent a tokens-per-second winner for the pair.

Local LLM inference
Token generation on a single GPU is often bandwidth-bound once the model fits. The 5070 Ti's 896 GB/s versus the 9070 XT's 640 GB/s is the published gap that would matter there. Capacity is a tie: 16 GB each. That window typically covers 7B–14B quantized models comfortably and 32B-class models tightly. Neither card is a 70B-class single-GPU fit without offload.
Our database holds one non-quarantined local-LLM row for the RTX 5070 Ti only: 87.54 tok/s on Qwen3-8B Q4_K_XL via llama.cpp llama-bench (CUDA 12.8), 16K context, batch 1, Ubuntu 24.04, source tier 3, labeled community_unverified, from hardware-corner.net, tested 2025-12-09, is_estimate=0. That is not a head-to-head result. No sourced RX 9070 XT token-rate row exists, so we do not publish a pair winner in tokens per second.
Software friction still favors the 5070 Ti: CUDA paths in llama.cpp, vLLM, and Ollama are the default. ROCm on RDNA 4 has improved through 2026 but still needs more setup on some stacks. That is a toolchain note, not a measured speed claim.
Image generation
Diffusion workloads care about VRAM first. 16 GB on either card fits SDXL at FP16 and many Flux-class quants without offload. We have no sourced images-per-minute rows for this pair, so we do not rank them on diffusion speed.
Which should you buy?
- Buy the RTX 5070 Ti if you want the higher published bandwidth (896 GB/s), the CUDA default stack, and you accept the $749 launch MSRP for the same 16 GB capacity.
- Buy the RX 9070 XT if budget leads: same 16 GB and 256-bit bus for $150 less at launch ($599), with 640 GB/s GDDR6 and a ROCm-class stack.
- Neither is a 70B-class single-GPU card. See the LLM inference guide. The nearby RX 9070 XT vs RTX 5070 page covers the 12 GB NVIDIA sibling. The live tool page is /compare/amd-radeon-rx-9070-xt-vs-nvidia-geforce-rtx-5070-ti.

How we know (and what we don't)
Every specification above is drawn from our RX 9070 XT (product 52) and RTX 5070 Ti (product 17) records, which pin vendor-published values from AMD's RX 9070 XT page and NVIDIA's RTX 5070 family page. Street prices are NULL. The only sourced benchmark cited is the single RTX 5070 Ti Qwen3-8B row above (tier 3, community_unverified, not an estimate). We have no sourced RX 9070 XT local-LLM measurement and no head-to-head pair, so we do not invent a tokens-per-second verdict.
