PyTorch Update Makes AMD GPUs Faster at Running AI
Could bring cheaper AI and a real alternative to Nvidia chips.
PyTorch powers the majority of today's AI models — from chatbots to image generators. Recently, developers pushed an update designed specifically for AMD's upcoming gfx1250 graphics chips. The update turns on a hardware trick called the Tensor Data Mover, which handles the movement of data inside the chip more intelligently. Instead of shuttling numbers step-by-step, the chip can move large blocks in one go, saving time and energy.
Why should you care? AI models are basically huge math problems — multiplying long grids of numbers over and over. Graphics cards are excellent at this, but they often stall while waiting for data to arrive. This update reduces that stall for a specific kind of math (dense matrix multiplication) commonly used in training and running AI. If it works as intended, AI tasks like running your own large language model on a home PC could become noticeably faster on AMD hardware.
This is also about market competition. Nvidia currently dominates AI computing, and its chips are expensive. Every improvement to AMD's software stack makes AMD a more credible alternative — which can drive prices down for everyone. The update is gated behind a setting that's off by default, so nothing changes overnight, but it represents the careful groundwork needed to deploy new hardware features safely. Two follow-up parts will extend this capability to other operations, like the attention mechanism used in modern AI models.
The catch? This is low-level plumbing. You won't wake up tomorrow with faster AI apps. It only helps developers using specific AMD chips and newer ROCm software. But for anyone hoping AI gets cheaper and less dependent on one supplier, this is a quiet, promising step.
- PyTorch added support for AMD's gfx1250 GPU chip's Tensor Data Mover feature, which streamlines data flow for faster math.
- This first upgrade targets dense matrix multiplication (mm and addmm) — the heavy lifting behind most AI computations.
- The feature is off by default and is part of a three-part rollout; the next two parts are expected to extend speed gains to more AI workloads.
- More efficient AMD GPUs could increase competition with Nvidia, potentially lowering costs for AI training and usage.
Why It Matters
Faster AI on AMD GPUs could lower costs and reduce tech's reliance on Nvidia chips.
