Nvidia reports FP16 performance, when they mention how strong their Tegra X1 is... why? cuz big numbers fool people. Sony & MS 's consoles are useing FP32 (twice as demanding) (16 x 2 = 32). Also known as half or full floating points. Thats why Tegra X1 is 1tflop fp16, but only 500 Gflops when you meassure it the same way as the PS4 or XB1.
Does that answear your question? in a head to head compairison it looks like this: FP32 the tegra X1 is just 500 Gflops (0.5 teraflops). FP32 the PS4 is 1840 Gflops (1.84 teraflops).
The tegra X1 is 512 Gflops(fp32) The tegra X2 is 625 Gflops (fp32) So its a upgrade, just not a gigantic one.
Basically 1/3 the power of the PS4. If your generious and say flops arnt all equal, you can probably give it a 10-15% boost or so. Point still stands, its closer to 1/3 than 1/2, of the power. That is assumeing they dont make a custom chip, or throw 2 of these chips into it or some such. |
Ok, makes sense. Always read about the fp16 number and thought to myself that 1Tflop aint that bad, and it fits right in to the Xbox One mold of performance especially if they went with X2's... but but but.. wasnt that good afterall :<
