In its RTX 4080 review (opens in new tab), Tom’s Hardware wrote that the GPU delivers 78% of the RTX 4090’s performance for 75% of the price. The RTX 4090 maintained performance when going from 1080p Ultra to 1440p Ultra to 4K Ultra. Tom’s Guide noted that the 55% average includes games like Microsoft Flight Simulator, which is still hitting CPU bottlenecks. There’s a 71% uplift compared to the RTX 3090 and a 77% improvement over the RTX 3080 Ti. We’ll use their benchmark results to compare the GPUs.įor its 4K gaming benchmark (which tested nine titles), the site found that the RTX 4090 Founder’s Edition (opens in new tab) averaged a 55% improvement over the last-gen RTX 3090 Ti. Sibling website Tom’s Hardware reviewed AMD and Nvidia’s latest cards. AMD Radeon RX 7000 vs Nvidia RTX 40 series: Performance But for applications that use a lot of VRAM, the RX 7900 XTX might prove more beneficial. Because of that, the two GPUs are effectively on-par in terms of balanced bus width and speed for gaming. With that said, the latter uses speedier GDDR6X memory. For example, the RX 7900 XTX has 24GB of VRAM (memory) compared to the RTX 4080’s 16GB. With DLSS 3, Nvidia claims the card is twice as fast in modern games as the GeForce RTX 3080 Ti and more powerful than the GeForce RTX 3090 Ti at lower power.Ĭomparing the company’s graphics cards isn’t exactly straightforward. The RTX 4080 has 9,728 CUDA cores and 16GB of the aforementioned high-speed Micron GDDR6X memory. It’s capable of consistently delivering over 100 frames per second at 4K resolution gaming, according to Nvidia. This GPU features 76 billion transistors, 16,384 CUDA cores and 24GB of high-speed Micron GDDR6X memory. It's also up to two times faster in modern games while maintaining the same 450W power consumption. (Image credit: Nvidia)Īccording to Nvidia (opens in new tab), the RTX 4090 with DLSS 3 is up to four times faster compared to last generation’s RTX 3090 Ti with DLSS 2. The RTX 4090 is Nvidia's most powerful GPU yet. For simplicity’s sake, chiplet designs let AMD stack individual self-contained "chiplets" tightly together in configurations that are potentially more powerful and power-efficient than a processor on a single piece of silicon. Our sibling site Tom's Hardware has an excellent in-depth interview with AMD's Sam Naffziger about entering the GPU chiplet era (opens in new tab) and what it means for the industry. Understanding how chiplet GPUs differ, performance-wise, from more traditional GPU designs is a complicated topic. AMD is more familiar with the technology, having already employed it in the design of its new Ryzen 7000 CPUs. What's perhaps more intriguing is that these are the first AMD GPUs to feature a chiplet design, something competitors Intel and Nvidia have not (yet) attempted. The Radeon RX 7900 XT and 7900 XTX are the first AMD GPUs built on the company's new RDNA 3 architecture.
