Gigabyte GeForce RTX 5090 WINDFORCE OC 32GB GDDR7
Sapphire Radeon RX 7900 XTX NITRO+ 24GB GDDR6 Silver
The Gigabyte WINDFORCE is for someone who needs 32GB of GDDR7 VRAM and a 512-bit memory bus for heavy AI or compute workloads, and is willing to gamble on a card with no real-world feedback yet.
Buy the Sapphire NITRO+ if you want a proven 4K gaming card with excellent cooling, quiet operation, and 24GB of VRAM that owners consistently rate highly across 688 reviews.
Principais diferenças
- VRAM is 24GB GDDR6 on the Sapphire vs 32GB GDDR7 on the Gigabyte, and the memory bus is 384-bit vs 512-bit. That's a massive bandwidth advantage for the 5090 in memory-hungry tasks.
- The Sapphire's base clock is 2510 MHz and boost is 2680 MHz, while the Gigabyte runs at just 990 MHz base and 1515 MHz boost. The NITRO+ is clocked way higher out of the box.
- Despite the Gigabyte's memory advantage, the Sapphire scores 92 total vs 66, with a huge gap in content creation (90 vs 51) and workstation (82 vs 55). The NITRO+ wins 19 spec categories to the Gigabyte's 6.
- The Sapphire has 688 reviews at 4.4/5 with owners praising its quiet operation, cool temps, and compact size, while the Gigabyte has zero reviews. You're comparing a proven card to an unknown quantity.
- Power draw is 339W on the Sapphire vs 175W on the Gigabyte. The NITRO+ needs a beefy 850W+ PSU, while the 5090 is surprisingly efficient for its class.
