# RTX 5060 Ti (16GB) vs AMD RX 9070 XT (16GB) for Local AI

> **Direct Hardware Verdict**: Both contenders pack an identical 16GB VRAM capacity under $650, splitting strictly along bandwidth versus ecosystem lines. AMD's $599 RX 9070 XT pushes 640 GB/s across a 256-bit bus (+42.9% wider than the 5060 Ti's 448 GB/s), generating ~53 vs ~37 tok/s on Qwen 2.5 14B Q4_K_M inside Ollama or llama.cpp. However, the $449 RTX 5060 Ti draws 124W less wall power (180W vs 304W) and delivers zero-config CUDA, NVFP4, and ComfyUI video kernel compatibility.

## Silicon Architecture & Thermal Analysis
This matchup pits Blackwell's narrow high-speed GB206 die against AMD's monolithic RDNA 4 Navi 48 (`gfx1201`) silicon. NVIDIA trims cost and board power to 180W by driving 28 Gbps PAM3 GDDR7 across a 128-bit PCIe 5.0 x8 package (448 GB/s), pairing it with 5th-gen Tensor Cores capable of native NVFP4/MXFP4 execution. AMD takes the opposite approach on Navi 48: a wider 256-bit GDDR6 bus at 20 Gbps delivers 640 GB/s backed by 64 MB of 3rd-generation Infinity Cache and revamped 2nd-gen AI Accelerators supporting native hardware FP8 WMMA under ROCm 6.4+. For pure text inference in Linux llama.cpp or Vulkan, Navi 48 streams tokens ~43% faster. Yet whenever workloads touch Python diffusion ecosystems—like HunyuanVideo 13B block-swapping or bitsandbytes 4-bit LoRA training—NVIDIA's CUDA stack avoids compilation friction.

## Tier 1 Free Software Optimization ($0)
On an RX 9070 XT under Ubuntu Linux, compile `llama-server` with `-DGGML_HIP=ON -DAMDGPU_TARGETS=gfx1201` (or export `HSA_OVERRIDE_GFX_VERSION=12.0.1` when legacy ROCm wheels omit RDNA 4) alongside `-fa on -ctk q8_0 -ctv q8_0`; on the RTX 5060 Ti 16GB, run Blackwell-native MXFP4 weights for instant prompt prefill speedups.
