Nvidia RT cores are also back – that's why Nvidia has the RTX name, after all – and they also see massive improvements. When you pair the uplift in CUDA cores, with massive boosts to cache, texture units and memory bandwidth – thanks to the move to faster GDDR6X memory on a 320-bit bus – gaming performance gets one of the biggest generational jumps in years, even if it does fall a bit short of that '2x performance' target that we're sure some folks were hoping for. This translates to nearly three times the theoretical FP32 throughput from around 10 TFLOPs to 29.7 TFLOPs – an absolutely massive generational leap.
What this means is that while the Nvidia GeForce RTX 3080 only has 46% more SMs than the RTX 2080 at 68, it nearly triples the CUDA core count, from 2,944 to 8,704. Outputs: 1 x HDMI 2.1, 3 x DisplayPort 1.4 Stream multiprocessors: 68 (128 CUDA per SM)

This effectively doubles raw FP32 throughput core for core, though this won't directly translate into double the frame-rate in your favorite PC games – at least, not for many of them. Through some clever optimization, Nvidia was able to double the amount of CUDA cores present on each Streaming Multiprocessor (SM) by making both data paths on each SM able to handle Floating Point 32 (FP32) workloads – a vast improvement over Turing, where one data path was dedicated entirely to integer workloads. There have been obvious improvements to the ray tracing (RT) and Tensor cores – which are on the second and third generation, respectively – but perhaps the biggest improvement has been to the rasterization engine. The fact that Nvidia has increased the power budget so much over the RTX 2080 while boosting power efficiency means that the overall performance profile is far above what any Nvidia Turing graphics card was capable of. The Nvidia GeForce RTX 3080 is based on the Ampere graphics architecture, which brings huge improvements to both raw performance and power efficiency over its Turing predecessor. The Nvidia GeForce RTX 3080 Founders Edition drops the USB-C video output, which we think is a shame. Nvidia GeForce RTX 3080: Features and chipset So even though the RTX 3080 is really expensive, compared to its peers and the card it is replacing, the MSRP price is actually pretty good given the level of performance you get out of it compared to the rest of this generation. It's not the cheapest graphics card around, but there are marginally better cards out there for twice the price. The reference card in our AMD Radeon RX 6800 XT review and the Gigabyte card in out AMD Radeon RX 6900 XT review have an MSRP of $649 (around £649, AU$960) and $1,299 (about £1,040 / AU$1,820), so the RTX 3080 is somewhere in the middle of the mix here among this generation of cards. The Founders Edition card in our Nvidia GeForce RTX 3070 review, meanwhile, is a much more relatively reasonable $499 (£469, AU$809). It's not as outrageous as the Founders Edition card in our Nvidia GeForce RTX 3090 review, which launched at $1,499 (£1,399, around AU$2,030). It's still ridiculously expensive, especially when you get to aftermarket cards. This is cheaper than the Founders Edition card in our Nvidia GeForce RTX 2080 review, which debuted at $799 (£749, AU$1,199), so that's a good thing. But every RTX 3080 should more or less be in the ballpark of performance as the one Nvidia itself has released. Just be aware that some of these aftermarket card designs may see steep price increases over this Founders Edition, based on things like exotic cooling solutions and factory-tuned overclocks. However, as with any major graphics card, there will be dozens of aftermarket graphics cards from companies like MSI, Asus, Zotac and more. The Nvidia GeForce RTX 3080 is available now starting at $699 (£649, about AU$950) for the Founders Edition. The Nvidia GeForce RTX 3080 is available now, assuming you can find it.
