Nvidia GeForce RTX 4090
The GeForce RTX 4090 is very fast, brutally fast. A key concern people seemed to have with the RTX 4090 was pricing and power consumption. It's clear now though that the rumors of insane power consumption were wrong, the 4090 isn't absurd in that sense, using less power than the 3090 Ti in our testing.

Nvidia GeForce RTX 4090 vs. AMD Radeon RX 7900 XTX: Essentially, if you want the best of the best, it's the RTX 4090, which appeals to those with ample budgets. The 7900 XTX, on the other hand, really has to earn your money. While it might be 18% cheaper than the RTX 4080 for similar overall performance, its ray tracing performance is often much worse, and its feature set can be lacking, either in support or quality.
