Nvidia GeForce RTX 4090 vs NVIDIA GeForce RTX 5080

The AMD Radeon RX 7900 XTX has 24GB GDDR6 memory and a $999 MSRP while the NVIDIA GeForce RTX 4090 has 24GB GDDR6X and launched at $1,599. In rasterization the 7900 XTX is often within 10% of the 4090 but trails by 30-50% in ray-traced and DLSS-enabled games.

The RTX 5070 Ti offers 16GB GDDR7 at 28Gbps on a 256-bit bus with 8448 CUDA cores, while the RTX 5080 provides 16GB GDDR7 at 30Gbps on a 256-bit bus with 10752 CUDA cores and higher TDP. Real-world benchmarks show the RTX 5080 delivering roughly 25-35% higher rasterization and ray-tracing performance than the RTX 5070 Ti at 4K.

The RTX 5090 has 32GB GDDR7 memory and 21,760 CUDA cores while the RTX 5080 has 16GB GDDR7 and 10,752 CUDA cores. Real-world tests show the 5090 is 35-45% faster than the 5080 at 4K but costs roughly $800 more.

The RTX 5090 offers 32GB GDDR7 at 1.8TB/s bandwidth and 575W TDP versus the RTX 4090's 24GB GDDR6X at 1.0TB/s and 450W. Real benchmarks show the 5090 delivering 35-45% higher rasterization and ray-tracing performance at 4K for $2,499 MSRP against the 4090's current $1,600 street price.

The RTX 5070 has 12GB GDDR7 memory and 8448 CUDA cores while the RTX 5080 has 16GB GDDR7 and 10752 CUDA cores. The RTX 5080 delivers roughly 35-40% higher rasterization and ray-tracing performance than the RTX 5070 at 4K.
