AMD Radeon RX 9070 vs NVIDIA GeForce RTX 5070 vs NVIDIA GeForce RTX 5080

The AMD Radeon RX 9070 is a high-end graphics card based on AMD's Navi 48 (N48 XT) that features 56 CUs (28 WGP). The model will feature 16 GB of GDDR6 VRAM with a 256-bit bus and 64 MB of total cache.

Performance

Our tests show that the card is 13% faster overall than the RTX 4080 in games, and 3% slower than the RTX 4080 Super. The higher-level RTX 9070 XT is 12% faster. 

Power consumption

The Radeon RX 9070 requires 220 watts of energy, but there are also custom versions from AiB-partners with 240-watt TDP.

The Nvidia GeForce RTX 5070 is a fast desktop graphics card utilizing the GB205 chip based on the Blackwell architecture. The model offers 6144 CUDA cores, and 12 GB GDDR7 graphics memory with a 192-bit memory bus (672 GB/s). The base clock of the GPU (reference model) is specified at 2.16 GHz, while the boost clock can reach 2.51 GHz.

Architecture

Nvidia GeForce RTX 5070 features new Tensor (5th Gen) and RT-cores (4th Gen), with 988 AI TOPS and 94 TFLOPS performance respectively. Blackwell architecture is the first to feature the new DLSS 4 Multi Frame generation, which, thanks to enhanced AI capabilities can generate more frames per second while using less memory and delivering better picture quality. Nvidia also managed to improve the performance and output quality of DLSS, Frame Generation, and Ray Reconstruction features (also available for the previous RTX 4000 series). Additionally, the new models now support Reflex 2 low latency mode and Frame Warp.

Performance

Thanks to the new Tensor and RT-cores, as well as some bump in CUDA cores, the card is promised (by Nvidia) to offer as much as 2x better performance compared to the previous RTX 4070 (thanks to the new DLSS 4 MFG feature). According to Nvidia's presentation, the card can even reach the performance level of the RTX 4090. The RTX 5070 is expected to be among the faster graphics cards of 2025 and, presumably, will deliver good performance in games at high resolution.

Our own tests show that the card is 4% faster than the RTX 4070 Ti in the synthetic benchmarks and almost identical to the Radeon RX 7900XT in games (RTX 5070 is 1% slower at 4K, 1080p, and 2K). 

Power consumption

According to Nvidia, the GB205 chip is manufactured using the modern 4N FinFET process at TSMC and is specified with a TGP (Total Graphics Power) of 250 watts (50 W higher than RTX 4070). Nvidia now also specifies maximum GPU temperature, which is stated at 85 ℃ for RTX 5070. The model also requires at least 650W PSU.

The Nvidia GeForce RTX 5080 is a high-end desktop graphics card utilizing the GB203 chip based on the Blackwell architecture. The model offers 10,752 CUDA cores (84 SMs), and 16 GB GDDR7 graphics memory with a 256-bit memory bus (960 GB/s). The base clock of the GPU (reference model) is specified at 2.30 GHz, while the boost clock can reach 2.62 GHz.

Architecture

Nvidia GeForce RTX 5080 features new Tensor (336, 5th Gen) and RT-cores (84, 4th Gen), with 1801 AI TOPS and 171 TFLOPS performance respectively. Blackwell architecture is the first to feature the new DLSS 4 Multi Frame generation, which, thanks to enhanced AI capabilities can generate more frames per second while using less memory and delivering better picture quality. Nvidia also managed to improve the performance and output quality of DLSS, Frame Generation, and Ray Reconstruction features (also available for the previous RTX 4000 series). Additionally, the new models now support Reflex 2 low latency mode and Frame Warp.

Thanks to the new Tensor and RT-cores, as well as some bump in CUDA cores, the card is promised (by Nvidia) to offer as much as 2x better performance compared to the previous RTX 4080 (thanks to the new DLSS 4 MFG feature). The RTX 5080 is expected to be one of the fastest graphics cards of 2025 and, presumably will deliver good performance in games even at 8K.

Our tests have shown that RTX 5080 is 6% faster than the closest Radeon RX 7900 XTX in synthetic benchmarks and outshines the previous 4080 by 19%. The same result can be seen in professional applications. In games, RTX 5080 is 33% faster than the previous RTX 4080.   

Power consumption

According to Nvidia, the GB203 chip is manufactured using the modern 4N FinFET process at TSMC and is specified with a TGP (Total Graphics Power) of 360 watts (40 W higher than RTX 4080). Nvidia now also specifies maximum GPU temperature, which is stated at 88 ℃ for RTX 5080. The model also requires at least 850W PSU.
