They both fit in my ATX motherboard, but the fans on the bottom-most card couldn’t avoid the case wiring for my Corsair Crystal 570X RGB case. I’d hoped to slap both in my system to test Davinci Resolve performance. I have a second 3090 here-MSI’s custom Gaming X Trio, which is also a beefy 3-slot design. But if your workload can scale up if you put more graphics cards in your system, drastically reducing completion time and potentially putting real money in your pocket, the size is something you want to take into consideration. And if you’re a prosumer who only needs one or two monstrous graphics card for your projects, the RTX 3090 Founders Edition’s size shouldn’t matter either. This beast takes a lot of space in your case. The RTX 3080 FE measures 11.2 inches long, while the 3090 FE is 12.3 inches. By contrast, the RTX 3080 packs in only 10GB of GDDR6X. While HBM2 helped the Radeon VII hit a massive 1TB/s memory bandwidth, GDDR6X’s advances help the RTX 3090 hit a blistering 936GB/s. The GeForce RTX 3090 offers 8GB more capacity. The 16GB of HBM2 inside AMD’s Radeon VII helped it win over creators more than gamers during its brief lifespan. More VRAM helps AI and analytics pros handle larger data sets. Creators need more capacity than standard gaming-class graphics cards provide when they’re editing 8K videos or processing other tasks. The RTX 3090’s mammoth 24GB capacity is the real draw for professionals. Again, read our RTX 3080 review for deeper Ampere details. That lets GDDR6X move data twice as fast as previous incarnations. It uses advanced “PAM4” signaling technology that can send up to four possible values per cycle, rather than the usual two. Nvidia teamed up with Micron to create GDDR6X, the ultra-fast new memory in the RTX 30. Two specs in particular should make professionals drool, though: The SLI connector, and the 24GB of GDDR6X memory. The D5 Render tool for architects already supports DLSS. In addition to the raw denoising and ray tracing speed boosts in rendering tasks, the 2nd-gen RT cores inside the RTX 3090 now support hardware acceleration for ray-traced motion blur, and applications can now support Nvidia’s DLSS technology to speed up their real-time visualizations. Several creative applications now support Nvidia’s OptiX technology, which lets them tap into the specialized capabilities of RT and tensor cores to speed up tasks. But Nvidia’s new-look cores can make an even more tangible difference for creators. The upgraded RT and tensor cores in Ampere GPUs help with playing ray traced games at 1440p and 4K resolution, alleviating a concern with the RTX 20-series. The GeForce RTX 3080 offers roughly 85 to 90 percent of the RTX 3090’s 4K gaming performance at under half the cost, as you’ll see in our benchmarks later. That gives the GeForce RTX 3090 a 20-percent advantage in raw specs, though it’s worth noting that it is not 20 percent faster in every workload. Power connectors: 2x 8-pin (with supplied 12-pin adapter)īy comparison, the RTX 3080 packs 68 SMs and 8,704 CUDA cores.Display connectors: 1x HDMI 2.1, 3x DisplayPort 1.4.
