4x CROSSFIRE ON MACBOOK PRO?!

What I mean is, the scaling from 1- 2, 2- 3 and 3 - 4 gets worse as you add the additional card. Depending on game you lose 20 - 40% performance per card running at 4x instead of 8/16x PCIE. Now also consider only the higher end AMD cards are able to run 4x crossfire. I would say (guessing) the performance would be worse than traditional 2 ways crossfire

thats what i wanna know, would you want to see the results? just for the laughs and gigs

If it did work, the performance gained from 4x gpus would be lost by the drop of bandwidth from 16 - 4x PCIE

but theoretically it could work, this was never about the preformance, its about pushing the limits of a shitty laptop chip with hardware for a few grand straped onto it

yah its because i find it amusing, it would be fun to see a macbook with 4 razer cores strapped to it

4X 3.0 == 8x 2.0 As has been tested many times be within 5-10% of PCIE 2 16x and PCIE 3 16x

Mac is great for gaming?

Not on the fury test I looked at earlier, dropped by like 30% at 1080pnonnsome games

It Will be with 4 gpu's.

Cpu is quad core with hyper treatding

I think this would work better if someone managed to fit the Macbook Pro with RGB lighting.  Just to really fuck with Apple.

i just came up what a amazing idea,

 

a razer core runs at a 4x pcie 3.0 link,

AMD radeon needs a 4x pcie 3.0 link to run crossfire

razer core needs a thunderbolt 3 (type c) link

the macbook pro 15inch has 4 thunderbold 3.0 (type c)

mac needs to run in windows?! for crossfire support?!

 

so in theorie you can run 4x rx480 or 4x a custom r9 fury.

if this has been done already please give he a LINK!

 

if you are going to try it, PLEASE LET ME KNOW

(total price ca    2800  x  4x 500 (2000) = 4x220 (880) = 5680 usd

                         mac   +   4x razercore   + 4x rx 480     = AWESOME

 

maybe this can go in the wan show of today?!

send to @LinusTech at twitter

I don't think you can run a CrossFireX set up with Razer cores, but if it would work, there wouldn't be a massive issue from the bandwidth, a single GPU will not use more than 32GB/s of bandwidth. But when you try to run 128GB/s of bandwidth from a single Thunderbolt 3 controller, you might have an issue there.

While it might work, I won't be spending €8,000 to test it, I could buy a vastly more powerful server for that that holds 8 dual or quad GPU cards.

wow it took nearly a day of this thread existing for people to get it haha, performance aside, we want a macbook with 1000 watts of gpu's strapped to it for no reason other than sheer amusement

this reminds me of a question i had regarding the matter, on the new MBP, does each thunderbolt port have it's own controller and own bandwidth ? could you saturate 40gb/s on each port simultaneously ?

[Centurius]

16 lanes isn't going to cut it, as other stuff also needs to come out of those lanes. Not just the external gpu's.

You are from floatplaen!!!

Can you present this plan to Linus or luke?!

Ps, don't Let it sint right?!

I've only ever talked to them briefly in messages, one about the pizza heater PC and the other about bringing back an old segment, the floatplane is only like €2.88 so that is really not much.

Well, 40Gb/s is only 5GB/s, barely enough for 1 PCI-e lane, so a single controller off a 4x lane would be enough, but you can't crossfire over Cores, I thought about it, the PCIe lane is being converted back and forth, there is not logical way to ensure the inter-card communication.

daisy chaining ? or is that too much, have i just broken the thread ?

Daisy chaninging PCIe over thunderbolt is about as bad an idea as I just made it out to be (sure it's confirmation bias but it still won't work)

[Festive]

I would love to see this in action.

well the consensus seems very logical, although, i won't feel better until ive seen it myself. I have 10 of the new MBP's coming at work soon and we have thunderbolt 3 gear so ill have a little play and keep you updated.

The raxer core's only have 1 in port not a second out port.

But every thunderbolt port has its own controller.

Is Just would be very interesting

I want in on the LTT channel, but thanks

Keep is all up to date.

Also have some amd gpu's laying arond?
