![]() ![]() In our testing, DLSS 3 largely performs in the same manner on the RTX 4080. Our investigation came after the launch of the RTX 4090 and remains the best place for a comprehensive breakdown of the tech. ![]() Since we tested Nvidia's DLSS 3 technology not a whole lot has changed, aside from the launch of a few more games supporting it. ![]() In addition to the increase in cores, there's the inclusion of 4th-gen Tensor cores and 3rd-gen RT cores, the GeForce 40 series also introduces DLSS 3, a feature that for now is exclusive to the new series. However, you won't need a new PCIe 5.0 compliant power supply as RTX 4080 comes with a 3x 8-pin to single 16-pin adapter, similar to the 3x 8-pin to 16-pin model supplied with the 3090 Ti. So we're not going to feed into that story as we believe a lot more investigation needs to be done before drawing any conclusions.Ī single PCIe 5.0 power connector can deliver up to 600 watts and previously that would require four 8-pin power connectors. A lot has been said about this connector over the past month, but what the real story is – in our opinion – it's unknown at this point. This means the GeForce RTX 4080 is still using the controversial 16-pin 12VHPWR power connector. Point is though, they physically look like the same product. It's also possible Nvidia made some changes to the cooling, but we didn't have time to tear it down for this review. Obviously there are some physical changes under the skin, we imagine power delivery has been cut down, the memory configuration has changed, and the GPU die is smaller. In terms of design, the Founders Edition RTX 4080 is identical to the 4090 on the outside, the only difference we can account for so far is the weight, the 4080 FE model is 3% lighter. The minimum power supply requirement is 750 watts and for testing we'll be using an 850w unit. That's the same rating given to the 3080, though the maximum GPU temperature has been downgraded from 93c to 90c. Nvidia claims a total graphics power rating of 320 watts for the RTX 4080. The RTX 4080 has been awarded faster 22.4 Gbps GDDR6X memory, a 7% increase there from the series flagship, though the smaller 256-bit wide memory bus means that overall memory bandwidth has been cut down by 29% to 717 GB/s. Given those figures it should be no surprise to learn that the 4080 packs 41% fewer CUDA cores than the 4090, the memory bus width has been reduced by 33% and there's 11% less L2 cache.Īs for core clocks, there's little difference between the RTX 40, we're talking 2505 MHz versus 2520 MHz for the boost clocks, with a slight advantage to the 4090. ![]() The 4080 still packs 62% more transistors than the previous-gen 3090 Ti flagship though. The GeForce RTX 4080 is based on the AD103 silicon which measures 378.6 mm2, that's a 38% smaller than the AD102 used by the RTX 4090 which sees a 40% reduction in transistors. In time for this review we also received partner models from PNY, Asus, and MSI, which we'll show off towards the end of the review. There's plenty to discuss and benchmarks to check out, but first let's touch on the specifications, take a look at the Nvidia Founders Edition model, and then we'll get to the blue bar graphs. Granted, the market has changed a lot since then, so it will be interesting to see what the RTX 4080 has to offer. It's time to review the new GeForce RTX 4080, Nvidia's latest $1,200 GPU, which is a massive 71% increase over the RTX 3080's MSRP, though of course Nvidia would prefer we forget that was ever a thing and instead focus on the $1,200 3080 Ti. ![]()
