News Nvidia To Support NVLink Only for RTX 3090

[spongiemaster]

You are totally wrong because in the past even mid range GPU had SLI , fro xx60 to xx80 ...

and dont worry much , SLI and Crossfire will continue to exist , actually they will come back , because Intel Xe Graphics GPU works by tiles , that is adding the same GPU and connect them inside the chip , this is similar to SLI ... Intel Xe graphics will bring back parallel GPU .. call it what you want to call it , SLI/Crossfire/Xe tiles

I don't believe Intel has made any indications that tiles are coming for gaming cards. If they do, it will not be like SLI. Any multi-chip gaming card going forward will have to be handled by the card itself and be transparent to the software. The multiple GPU's will have to look like one big GPU to the software because multi GPU solutions have gotten too complicated and niche for gamer developers to support any more with development time.

They have no choice ,

Each tile is 10 Tflops as they said .. so in case they want to compete , to reach 20 and 30 Tflops ,their only choice is releasing the tiled GPU for the desktop market or leave the competition alltogether.

As for the drivers for Tiles it will be similar for SLI drivers .. does not matter it is the same concept but in much much lower latency.

Tiles will be like multi cores CPU , it is for the Developer to code the software to take advantage of many cores , the CPU itself wont take care of it as you said. the same for GPU Tiles. If the games Dev did not use other tiles it will be slower .

Here is what I expect

1- Mid range card 1 tile to cpmpete against rtx 3060
2-above it 2 tiles Xe 20 Tflops against 3070
3- 3 tiles Xe 30 Tflos against 3080
4- 4 tiles maybe will win against RTX 3090 ~40 Tflos

I'm still debating this. Only reason i see it at this point is for folding, and well ive been so used to buying 2 since the 9800GTX days it just seems normal to me to sli. It was sad when i paired two 1080tis FTW3 just to see games do worse in performance then better for some of those Big triple AAA titles it really disappointed me. The only thing SLI is good for.. Well drop the sli and just run two cards to folding goodness. Anyone with me in the folding department? Lets do this 3090's all day everyday!

SLI/crossfire works at driver level

mGPU from DX12 works at AP level. so directly configurable by game's devs. but they don't because it's not cost effective to do so

Xe Tiles works at hardware level, like infinity fabric from AMD . it's MUCH better since all the system sees is one GPU. the card(s) take care of all the load balancing.

AMD already uses infinity fabric for multi GPU's on they MI50 GPUs I really hope they use this on desktop cards for RDNA2

Massive parallel processing is how the brain functions and at relatively low Hz. If pure speed were the most efficient/effective way to function, genetics would have taken that route instead. I think we will find technology mirrors that over time as it becomes more refined and harmonized with sustainability (assuming we make it that far/long...).

I always chuckle when I see people take this line of thought - I can't afford this - therefore it sucks!

The reason people say "if you build it they will come" is because for everything we have, there were early adopters and people with extreme requirements who push technology forward.

I had a an Apple in 1986, I had a 486DX2-66 Gateway 2000 that came in a cow-themed box, I ran the first Linux release, I had 3DFX Voodoo - and now I have a 3790X paired with a 2080Ti which will be replaced with a 3090 soon.

Games aren't photorealistic yet - so when people say "most games run fine" it's because they are targeted at the middle of the curve capability wise, and when that curve goes up the engines are rewritten to take advantage of all the new features.

RTX sucked last time, as most 1.0 releases do - because it was laying the groundwork for 2.0 - and there will be a 3 and a 4 and then a young person won't believe you when you tell them "we didn't used to have that" just like with cell phones now.

We're not that far off from homes having a central home compute core just like we have HVAC units - with all the devices in the home running off of it with low latency displays powered by 60GHz 802.11ax and it's crazy low latency or fiber.

I already do this today, I use moonlight to connect my older systems and displays to my most powerful rig upstairs - I can play Overwatch downstairs on the big screen with no delay and get just as many headshots as on my main system.

If we deploy centralized systems with multi GPU, it will power different systems across the home - and once that hardware exists - Microsoft or the engine developers will add intogames or DX13 or 14 or 15 the ability to tile the rendering into quadrants for a mindblowing experience - and 5 minutes later everyone will be asking when 2.0 comes out.

The reason we have render farms is because at a certain point - you must scale out to achieve more performance - and that is what SLI is.

I remember when Tom founded this site, and it's gone downhill since he left.

Both ! not only Driver level.

Wrong , it does not see it as one GPU ... and AMD infinity Fabric is just connection between CPUs and NOT grouping CPUs into one
