Green500 shows Nvidia's Grace-Hopper superchip is a power-efficiency beast

Despite growing alarm over spiraling datacenter power consumption, this spring's Green500 ranking of the world's most sustainable publicly known supercomputers shows that the same energy-hungry server accelerators behind the AI boom are also driving sizable improvements in efficiency. Seven of the ten most power-efficient …

LPDDR5x, ConnectX-8, et al

When am I going to be able to buy a compatible motherboard online for my PC ?

I want all that juicy bandwidth too.

Re: LPDDR5x, ConnectX-8, et al

Yeah, but will it be able to run Crysis?

So this article is very misleading...you say that the energy efficiency has markedly improved since previously but that doesn't mean that they are using less energy - they are using more - much more!

One might even argue, unsustainably more.

I like to invert those GFLOPS/Watt figures, and multiply them by 1000, to get the number of Joules of energy needed to perform one trillion 64-bit floating point operations on theses machines (1 trillion = 10¹²). For example, 64.8 GFLOPS/watt corresponds to 1000/64.8 Joules per Teraflop, that is: 15 J/TF.

The #1 machine in Top500 back in June 2002 was the NEC Earth Simulator that executed 35.86 TF/s at 3.2 MW (i.e. 3.2 MJ/s) which corresponds to an energy consumption of 89,236 J/TF, or 6,000 times more than today's 15 J/TF.

In other words, in 22 years, we've improved the energetic efficiency of our top computational systems by six thousand times (today, performing a 64-bit floating-point computation takes one six-thousandth of the amount of energy it took back in 2002).
