NVIDIA’S GEFORCE GTX 1080 is a monstrous bit of gear (review, pg. 74). It is also expensive, at $700 for the Founders Edition. Its little brother, the GTX 1070, is about to arrive at a more affordable $450 ($380 for the non-Founders Edition). It carries a cut-down version of the same 16nm core, 1,920 CUDA cores against 2,560, and slightly slower clocks of 1,506MHz and 1,683MHz boost, against 1,607 and 1,733MHz. The 8GB memory is slightly slower GDDR5, and five of the 20 streaming multiprocessor cores are disabled. TFLOPS is down from nine to 6.46, still out-gunning the 5.6 TFLOPS of the GTX Titan X. As before, all this is achieved with low power consumption: 150W TDP. We still have the same banging 16nm Pascal GP104, so we can expect…
