multi-GPU as the future of graphics

mGPU, explicit multi-GPU, or SLI. Call it what you like but the age of the single GPU is coming to an end. We know this because it's what every hardware making is planning for - and that's a very good thing for us.

A major player in the game engine space is on board with the future.

“CRYENGINE 5.8 will build upon CRYENGINE 5.7. CRYENGINE 5.8 will add support for Multi-GPU DX12 configurations.”

Don’t expect it for a year though and even then it’ll take a while for developers to release anything using it.

I'm hoping that since everyone is moving to MCM this will push mGPU to become more common as well. It's a lot more consumer friendly over $1400 GPUs!

had multiple xfire and sli rigs. lets hope multi GPU makes a comeback

Thanks for that video. I think that your analysise are top tier, you should have as many subscribers as Adored!. Keep making videos, they are great!

We will definitely need it for Ray tracing. Seeing there were real time Ray tracing demos with GTX 600s cards in real time with no denoise a few years ago. I bet that if you could put a single high-end card to do only Ray tracing calculations and other card to do everything else, with a modern denoiser you could potentially have a modern game complete ray traced. And it would look insane seeing Quake II and Minecraft transformation.

Improvements on single ships won't deliver the performance needed to achieve full real time ray tracing of a scene. Unless a break through on graphene or carbon nanotubes happens and we get GPU ruining at hundreds of gigahertz.

Jesus, this is incredibly well done dude.

Amazing video! As a new 2 GPU owner this is the information I needed to know. Thanks for the detailed information. Keep it up!

Bro. This is great content. Keep it up!

Never materialized. They've been touting this since they started advertising Windows 10.

Deus Ex was supposed to support Multi-GPU but it doesn't. There was a beta release at some point that was supposed to offer MGPU "Preview" but it's not available anymore on Steam. M-GPU is supposed to let you use disparate GPU's anyway (as opposed to more traditional SLI/Crossfire using identical cards). I have an RTX 3090 and an RTX Titan, but I can't use them both in Deus Ex, Tomb Raider, or any of these other games that were "supposed" to support M-GPU. There is no option to enable both cards, and I can easily tell that only the 3090 is being utilized.

Maybe dedicated dies for running ray tracing is a better way to do it.
Nvidia is shooting themselves in the foot by putting RT and Tensor cores in dies used in gaming GPUs.

Though the ideal solution is to wait a couple of years and run raytracing on regular GPU cores.

Multi-gpu usage is such a missed opportunity, especially for affordability for the consumer, and not to mention VR.

Almost everyone I know who who gets a new GPU always keeps their previous one as a backup, just in case something happens, or so their friend can buy it off them and upgrade their own rig.
It's a shame to leave potential additional computing power sitting in a box, unused, just because the devs and drivers don't work with it. or the cards HAVE to be identical. Not to mention that the people who just make e-waste when they throw theirs away.

mGPU usage would really lower the price of an upgrade to your rig, you would just be adding to the build, instead of replacing the entire subsystem. This would also make VR experiences INCREDIBLY way more accessible, considering that each frame needs to be rendered twice, (one for each eye to provide stereoscopic video) having the work offloaded between 2 cards instead of one would be WAY better for Optimization, especially if it uses split frame rendering, some headsets use a single panel screen and split it in half for each eye, so split screen rendering is a match made in heaven.

As somebody with a budget build, it makes me sad that I can't run both my cards together, buying a new component is a big deal whenever you decide to do so and requires money to do so, and some people don't have that money to spend. LET US USE OUR CARDS, NVIDIA! I don't want to sell my kidney for afford even a 1080ti, and the 1080 is outdated now, the current generation is not a 16x0 or 20x0, ITS 30*0! WHY DOES THE 1080 STILL HAVE THE SAME PRICE AS A USED CAR?

Wow man awsome vid so professional everyone ln youtube has mis information and are all about advertising this is hardline stuff,

Would you make a tutorial of how to run mutiple gpus in 2020? I have 3x 7970s and works well in certain games when i say well like amazing but others nothing at all only 1 card

[sieurbzo]

As a developer, is it possible to use explicite mGPU programming with Vulkan (e.g. 4 GPUs) to render four different scenes, each using its dedicated GPU *and* with each GPU connected to its dedicated monitor (over DisplayPort)? All this with 4 GeForce cards?

[GeneralGuts]

Lets see what intel brings out next year..could shake the market new 'gpu core2' inside lol

[isbestlizard]

i don't get why this is such a huge problem.. just literally, if you have n GPU's and want to run at 240fps.. each one has a 240/nth of a second to build a frame.. just stagger them so they're ready at the right intervals and juggle n copies of visual game state rather than 1
