Question Why Crossfire and SLi is no longer available?

[HuNTeR-]

Why dual-gpu era is dead since 2013-2014?For example,i miss time when HD 5970, HD 7990 or gtx 690 was present.
For me Multi GPU is fantastically useful for many, many things,is raw power in a single motherboard slot.I mean what is the reason behind discontinuing dual GPU cards?I want to understand.Since 2013 both company Radeon and GeForce stopped their production of multi gpu solution for consumers.Why they don't want to revive again this solution in present?They are focusing only on single core GPU card

First reason, its not needed. a 4090 is many times more powerful than the latest from 2014. Going to guess, but like 6 times as powerful, at least in that area.

I just looked. Here: https://www.gpucheck.com/gpu-benchmark-graphics-card-comparison-chart

a 7990 is rated at 74, and a 4090 is 430 Thats about 5 times the speed. The other cards get worse from there.

Games stopped being optimized for and eventually just stopped supporting multi gpu so that killed it off.

Deferred rendering was the end of SLI and CF. Nothing to do with how fast GPUs are or anything.

I would prefer if Microsoft put multi-gpu rendering into DirectX so we could combine Nvidia/AMD/Intel cards and even the iGPUs together and make each render specific things in the game to distribute the load. PCIe 4.0 8x slots for three cards in tandem should be enough for the communication, no?

DX12 did include some way of managing multiple gpus (from what I understand) as can be seen below
