News RTX 4090 Beats Two RTX 3090s in SLI — Barely

[Admin]

YouTuber Benchmark Lab pits two RTX 3090s in SLI formation against RTX 4090; RTX 4090 wins, but just barely. And only because SLI doesn't work.

As pointed out in the article SLI is dead and have been for awhile now. So I would take these unoptimized 3090 SLI numbers with a huge grain of salt.

This is a very unsurprising result.

"that Benchmark Labs managed to run using some unknown SLI-enablement magic."

This makes this article completely useless. 🙄

In theory, if we could get anywhere close to 100% utilization on both GPUs, we would probably see the 3090s in SLI outperform the 4090 by a good margin

In reality we'd see $2000+ of video cards performing higher than ~$1600 of video card while lacking support for DLSS 3.0.

Not useless.
Shows the folly of trying to chase "SLI" with current GPUs.

Sounds like bull to me. In reality (having just bought a 3090 this month) you can get three 3090's cheaper than one 4090 currently. If SLI scaled well and wasn't such a mess around, I'd definitely consider a second.

And news at 11 —- SLI is STILL dead

In Port Royal, my SLI 3090s still beat a 4090, with the exception of the world top overclockers using LN2 to cool a 4090. I'm getting 31,000-32,000 scores in Port Royal. However, for gaming, the 4090 is faster because very few games support SLI with 3090s.

One of the main reasons SLI is dead is the person at Nvidia that ran and promoted SLI left the company. Very few games support Explicit Multi GPU in DX12 even though its easy to implement.
