AMD's decision to start off with mid-range RDNA 4 GPUs now seems prescient. NVIDIA's high-end RTX 5090 and 5080 are already selling well beyond their absurdly high prices, if you can find any in stock at all. And while the RTX 5070 Ti impressed us, it's already selling for close to the 5080's 1,000 launch price. Now AMD's Radeon 9070 and 9070 XT, which are set to arrive on March 6, have the chance to swoop in and deliver some serious competition. Based on early briefings from AMD, which include some impressive benchmarks (still untested by us), the RDNA 4 GPUs appear to be compelling 4K and 1,440p for discerning gamers who aren't ready to drop four figures on a video card.

How much should you spend? Should you buy one now or wait? And, of course, should you go with Nvidia or AMD? On the CES floor, PCWorld's Adam Patrick Murray joined forces with Tom's Hardware executive editor Senior Editor Jarred Walton for a chin wag on the state of the GPU market. You can see their full discussion in our YouTube video below.

Artificial Intelligence and deep learning are constantly in the headlines these days, whether it be ChatGPT generating poor advice, self-driving cars, artists being accused of using AI, medical advice from AI, and more. Most of these tools rely on complex servers with lots of hardware for training, but using the trained network via inference can be done on your PC, using its graphics card. But how fast are consumer GPUs for doing AI inference? We've benchmarked Stable Diffusion, a popular AI image creator, on the latest Nvidia, AMD, and even Intel GPUs to see how they stack up. If you've by chance tried to get Stable Diffusion up and running on your own PC, you may have some inkling of how complex -- or simple!

The GeForce RTX 4090 is an absolute monster of a graphics card, but the battle for the next generation of GPUs is only getting started. On Thursday, AMD revealed its own 4K gaming champion, and the Radeon RX 7900 XTX and 7900 XT aim to topple Nvidia's goliath with help from a stash of smart tricks that could make David himself blush. In addition to improved ray tracing capabilities, the addition of AI cores, and memory galore, these first RDNA 3-architecture GPUs are also the first graphics cards featuring a multi-die "chiplet" design, swiping inspiration from AMD's epic Ryzen success. Just like when Ryzen disrupted Intel's stranglehold on CPUs, moving to chiplets helps AMD drastically undercut Nvidia's pricing. While the RTX 4090 costs a chest-clutching $1,599, and the impending GeForce RTX 4080 costs $1,199, the new 24GB Radeon RX 7900 XTX costs $999 and the 20GB RX 7900 will cost $899 when they launch on December 13.
