With well over a 30% performance increase over the RTX 4090 in most tests, this new Nvidia gaming GPU definitely appears to be fast.

NVIDIA's new GeForce RTX 5080 shows early benchmark results: 15% faster in synthetic 3DMark testing than the GeForce RTX 4080 SUPER.

The GeForce RTX 5090, a new flagship GPU powered by NVIDIA's "Blackwell" architecture that features fifth-generation Tensor Cores and fourth-generation RT Cores, will deliver 20% improved performance on average versus its Ada-based predecessor,

The RTX 5090 offered the most improvement in Steel Nomad (4K), scoring 14,133 points—some 53% higher than the RTX 4090’s 9,216. The previous-generation card did close the gap in other tests, like Time Spy Extreme (2160p), where the RTX 5090’s advantage dropped to 31% but still gained an average advantage of 39% over the RTX 4090.

Leaked benchmarks show some eye-opening synthetic gains, but real-world gaming is more like a 20% uplift on average compared to NVIDIA's RTX 4090.
