The upcoming Nvidia GeForce RTX 5090 GPU could have 5,000 more CUDA cores than last generation with a 600 W default TGP.
With how big Nvidia's current 40-series GPUs are, I'm not looking forward to the mammoth size of the rumored 5090.is already so big that any PC builder worth their salt knows that you’ll need specialized brackets just to keep it from falling and dismantling your computer. The anticipated RTX 5090, Nvidia’s supposed next large and in-charge GPU, is set to be an absolute monstrosity of a graphics card.
The 50-series GPUs include an RTX 5080 with 10,752 CUDA cores and 16 GB of GDDR7 VRAM. The RTX 5090 contains a ludicrous 21,760 FP32 CUDA cores and 32 GB of VRAM on a 512-bit bus. Otherwise, the step down from that—the 5080—is a relatively subdued upgrade from the 4080. It contains 1,024 more CUDA cores than the last generation, though it has the same amount of V-RAM with a 176 GB/s jump in memory bandwidth. The leak suggests the 5080 is pulling 400W rather than the previous 320W.
There’s still so much we don’t know about the card, such as its other core values, clock speeds, or cooling apparatus. With those speeds, it would certainly run hot. Kopite7kimi previouslythe RTX 5090 Founders Edition has a 2-slot cooler rather than being a 4-slot GPU. This makes some sense, especially if Nvidia hopes customers to set the graphics card in anything other than a massive tower.
Both 5080 and 5090 will require a PCIe 5.0 slot, which debuted earlier this year. That’s expected, but it also reminds consumers that they will need to procure a new motherboard if they hope to upgrade from any PCIe 4.0-based graphics card. Both GPUs seem like solid upgrades for performance in high-resolution gaming. That being said, the 5090 is practically double the supposed performance of the 5080, making me wonder just how costly the card will be at release. You’ll also need to deal with CPU compute power limiting the actual performance gains of any new card. In today’s current games environment, the 5090 seems more built for enterprise heavy lifting rather than game performance.
