Intel slide of future GPU shows it could use 400 to 500 watts with 4 'stacked' chiplets
Website Digital trends have uncovered a slide originating from intel, that by itself is nothing that special however it holds info on a future Intel GPUs can have a hefty TDP of up to 500 watts.
The graphics processor would be chiplet based, much to what AMD is doing with Threadripper and Ryzen 3000. In fact, four, what is referred to as; tiles make a chiplet. The interesting part is that some TDPs are noted down as well, running to 400 and 500 watts indicative of a datacenter product. The chiplets are different from AMD's technology, as Intel would stack them with their foveros technology, much like an HBM2 stack on a graphics processor. In between the stacks you'd find an embedded multi-die interconnect bridge, in combination with pcie 5.0. Earlier info indicated that a each shader cluster would hold 128 EUs. So that's 512 EUs total.

but they can have 2x150W from PCIe cables and 75W from PCIe slot, so 375W in total. And that's the current regulation. They can't have 400W, let alone 500W....On the other side - chiplets! Means a lot more for future Intel CPU design than for fairy tale 500W GPU.

You can probably add another PCIe cable, might require a bit more from PSU...
They started to share some info on the inter chip communications last year? The idea probably was doing chip/GPU/FPGA and maybe some memory on a separate die..
But with AMD doing so well with chiplets, maybe the plans can/have changed.

If you look at the table, the 500W monster requires a 48V input. Normal PC PSUs don't even offer that. So, it's clearly meant for some server stuff, where they would have a different kind of power supply and thus can get away from the normal PCIe regulations.

There's a lot more red and yellow squares on that table than green ones
