A few days ago, Amazon announced its cloud game service Luna, which will naturally become a competitive product of Google stadia, Microsoft Project xcloud and Sony Playstation now.

However, after Amazon announced the background hardware configuration, it was questioned by netizens.

According to Amazon,The bearer Luna is a combination of Intel Cascade processor NVIDIA Tesla T4. The processor has nothing to pick,But the video card seems to have almost meaning.

Although the nominal single precision floating point of Tesla T4 is 8.1 tflops, which is in line with RTX 2070 super, including 2560 CUDA quantities.

However, the fatal weakness of T4 is that the video memory speed is only 10Gbps, and the total bandwidth is only 320GB / s, which is significantly lower than the 448gb / s of RTX 2070 and even worse than RTX 2060. The frequency is even more ridiculous. The basic frequency is set at 585mhz. Although the acceleration can reach 1590mhz, the 70 watt thermal design power consumption will be a huge hindrance.

What's more, even if T4 can be aligned with RTX 2070s, it's hard for the latter to run 4K games.
