Gainward GeForce RTX 3090 and RTX 3080 Ampere Pictured, Slides Confirm Specs

A mega dump of the Gainward GeForce RTX 3090 Phoenix GS and RTX 3080 Phoenix GS reveal not only the common board design of the two cards, but also the final specs of the RTX 3080 and RTX 3090. The RTX 3090 features 5,248 CUDA cores, and 24 GB of 19.5 Gbps GDDR6X memory across a 384-bit memory bus, which belts out 936 GB/s of memory bandwidth. The Gainward Phoenix GS runs the RTX 3090 at 1725 MHz boost frequency. The RTX 3080, on the other hand, features 4,352 CUDA cores, and 10 GB of 19 Gbps GDDR6X memory across a 320-bit memory bus, with 760 GB/s memory bandwidth. Gainward is running the RTX 3080 at 1740 MHz on the Phoenix GS.

What’s interesting is the board power figures put out by Gainward. The RTX 3090 typical board power (at least for the Phoneix GS), is rated at 350 W, while that of the RTX 3080 is rated at 320 W. These explain why we’re seeing custom-design RTX 3090 cards with either three 8-pin PCIe power connectors, or in case of the Founders Edition card, the 12-pin connector that’s capable of 600 W power delivery. Many of the custom-design RTX 3080 cards we’ve come across have two 8-pin PCIe inputs. The slides also list out “2nd generation RTX technology,” and “3rd gen tensor cores.” Gainward’s board features a meaty triple-slot, triple-fan cooling solution that has RGB LED illumination. We predict Palit’s cards to look very similar to these (with different cooler shroud designs).
