The sheer amount of gaming performance available requires a beefy cooler to keep it from overheating and as such you may find it a struggle to cram it inside a smaller PC case. Finally, you'll need to bear in mind the size of this GPU. To be safe, we recommend a PSU with a capacity of at least 900W. This will be much better once more ATX 3.0 PSUs hit the market and we can supply power through a single cable, but for now, you will need to carefully attach multiple PCIe cables and hope your PSU won't be overloaded. It's rated at 450W and requires a new 12VHPWR connector. It's the first Nvidia GPU to support DLSS 3.0 and has HDMI 2.1 outputs on the back.Īs well as the price, the RTX 4090 is a very power-hungry GPU. ![]() We're talking about 16,382 CUDA cores, 24GB of GDDR6X VRAM, a base clock of 2.23 GHz, and Nvidia's 3rd-gen ray tracing cores. How it's able to perform all this magic is due to the specifications. Like all other RTX 40 graphics cards, the RTX 4090 is built on the latest Ada Lovelace architecture. For example, using the RTX 4090 with DaVinci Resolve, we managed to encode a 4:30 long 4K60 video at a bit rate of 40,000 using NVENC in just 96 seconds. The RTX 4090 is the first Nvidia GPU to come with support for hardware AV1 encoding, though the NVENC encoder is no slouch either. As well as games, the GPU can be used in specific applications like media rendering. It comes alive for those with the best 4K panels and content creators. And we've found in the past AMD is usually better at improving the overall performance of its graphics cards through driver updates. At an MSRP of $999, it's not affordable but is a more reasonable price tag for a flagship graphics card. You'll have absolutely no problem, playing all your favorite games at 4K with this GPU. ![]() We found it to be comparable to the NVIDIA GeForce RTX 4080 GPU, though coming in considerably cheaper. Overall, it's the most powerful GPU from AMD, as we confirmed in testing for our in-depth review. You will require a beefy power supply as AMD recommends at least an 800W PSU and the Radeon RX 7900 XTX is capable of pulling 355W of power. You will be sacrificing around 3 PCI slots inside your PC case and AMD states it has a length of 287mm, so make sure your chassis can take such a card. You've got all the usual high-end GPU features here, including ray tracing support and AMD's excellent Radeon Super Resolution, the latter of which is essentially NVIDIA DLSS for AMD GPUs. For cores, we're looking at 6,144, which does fall short compared to what NVIDIA offers with its RTX 40 series GPUs, but it's able to make up ground elsewhere with faster clock speeds and higher memory bandwidth. ![]()
