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

The KFA2 GeForce RTX 4070 EX Gamer uses a custom-design to offer high performance, low operating temperatures and a silent operation. Galax, one of the largest GPU brands worldwide, is behind this product. 

After the RTX 4090, 4080, and 4070Ti, NVIDIA released the more affordable RTX 4070 model, which uses the same chip as the 4070Ti, the AD104, with some changes to decrease performance. The differences between the 4070 and 4070Ti models are shown below

  • 5888 Cuda cores vs. 7680
  • 64 ROPs vs. 80
  • 2475 MHz boost clock vs. 2610 MHz

The amount of memory and its speed is at the same levels as the 4070Ti unit, so you get 12 GB of GDDR6X with 21 Gbps bandwidth. Moreover, the KFA2 GeForce RTX 4070 EX Gamer has a higher boost clock, at 2535 MHz. Because of the low TDP, 215W, 15W higher than the RTX 4070 FE, Galax decided that there is no need for a 12VHPWR connector, so it went with a single 6+2 pin instead. If anyone decides to purchase this product, he/she won’t be troubled in replacing the PSU with an ATX v3.0 unit featuring a 12+4 pin connector. Nonetheless, a PSU usually outlives several GPU generations, so if you want to replace it, better go the ATX v3.0 way.

The GeForce RTX 4070 is based on the AD104 GPU and equipped with 5,888 CUDA Cores providing 29 FP32 Shader-TFLOPS of power for rendering traditional rasterized graphics, 184 Fourth Generation Tensor Cores offering 466 Tensor-TFLOPS (with Sparsity) for AI processing and DLSS, 46 Third Generation Ada RT Cores capable of 67 RT-TFLOPS for powering ray-traced graphics. Like all GeForce RTX 40 Series GPUs, the RTX 4070 supports Shader Execution Reordering (SER), the new RT core engines, and DLSS 3, so it is future-proof.
