KFA2 GeForce RTX 4070 EX Gamer Performance, Power Analysis & Noise Output

Epilogue

Although I measured up to 228W sustained power consumption during Furmark and close to 203W during gaming, while power spikes exceeded 271W, I still didn’t encounter any problems with the single 6+2 PCIe connector. Given that each wire can easily handle up to 7A and there are three wires carrying the 12V rail in a 6+2 PCIe connector, the latter can deliver up to 252W without any issues. This is 49W lower than what I measured during Cyberpunk gaming, and even in Furmark, the sustained power consumption didn’t exceed 228.

There is no need for an ATX v3.0 PSU for the RTX 4070, and the best processor to match this card is the AMD Ryzen 7 7800X3D, which is also highly efficient. A good 550W PSU can easily handle such a combination. If you choose a power-hungry Intel or AMD CPU, like the Intel 13900K, investing in a 650W unit would be better.

In terms of performance, the RTX 4070 is notably stronger than the 3070 Ti, and given that it costs $200 less than the 4070 Ti, it looks to be a good option for gamers that don’t want to spend much and play mostly at HD and QHD resolutions. I suggest you enable DLSS if you want to play with ray tracing enabled. It depends on the game, of course. The frame generation of DLSS 3 is a great advantage for all RTX 4000 series graphics cards, vastly improving performance, and given that the RTX 4070 is not a 4K card, I don’t expect the 12 GB VRAM to be a problem, even in the long run. If you are troubled though with the 12 GB VRAM and need 16 GB at least, you should look at the AMD Radeon RX 6800 XT and 6900 XT, which are now offered at very good prices, but the ray tracing performance is not that good.

If KFA2 manages to sell this product at the MSRP price of $600, it will be a decent deal. Still, it is not affordable, but the build quality is high, and the card runs silently. The fact that you won’t need a new generation or a strong PSU is another major asset.
