[Fudzilla] Apple 2016 laptops will have AMD GPUs

[VulgarDisplay]

I don't think CUDA even runs on AMD hardware. I am just observing that Adobe products run better on CUDA than they do on OpenCL.

Cuda running better on nvidia than open CL does not mean cuda is faster than open CL was the point I was making.

Isn't Apple abandoning OpenCL? I don't remember where I read it..

???
They created Open CL and Metal is their own customization of it!
nVIDIA won't help Apple since they have CUDA and Intel is slowly being out of the game too due Xeon Phi (despite using Open CL too)

It's anybody's guess.

If the 480 is a cut down part and a 'full' part exists, what are the yields like for both? Will the expected demand for $199ish cards be high enough to warrant artificially disabled full parts? I hope so, for selfish reasons. Being able to unlock the 6950 was the sole reason I bought one instead of another card several years ago.

I can see the debates now: Buckets of overclocking vs parts unlocking!

If yields are that good, and demand is that high, then expect a price cut to the full part.

Do we have any further information that the Polaris 10 retail desktop part is cutdown? 36CUs does seem like an odd number to go with.

I think we will see a different structure.

Given the small die size and TDP of Polaris 11, this is how I think it's gonna happen.

MacBooks smaller than 15 inch will have Polaris 11. The MBP gets Polaris 10.

5K iMAC gets Polaris 11/10. MacPros obviously Polaris 10.

Apple's volumes are huge. 2016 is going to result in AMD winning back a ton of dGPU market-share.

I wish this were the case, but I highly doubt it.

Even after a possible revamp, I expect:
MacBook: iGPU
MacBook Pro 13" (base - top spec): iGPU
MacBook Pro 15" (base spec): iGPU
MacBook Pro 15" (top spec): Polaris 11
iMac (base - top spec): Tonga - Polaris 10
Mac Pro (base - top spec): dual Tonga - dual Polaris 10

It is a bummer if you are stuck with Adobe products on Apple as they usually tend to perform better under CUDA than OpenCL. I would love to see Adobe optimize their CC suite the way Apple optimize Final Cut Pro with OpenCL/Quicksync.

This post should be accompanied by comparative benches. Without them it's just baseless claims. Just saying.

I'd mostly agree, but I don't see a need for Tonga any more.

I really hope for Polaris support in OSX.

It's a shame AMD does not provide a standalone driver like nVidia does, it's the main reason why I had so many nVidia cards.

Maybe, but they did keep Tonga in that refreshed 4xx mobile chip line they did.

Rather confusing why with it seemingly intended sandwiched in between P11 and P10 and the obvious power draw disadvantages, so maybe this sort of reason?!

OpenCL wasn't even supported until Adobe CC 2014 or 2015. The last perpetual license version you could buy was Adobe CS6 and only CUDA was supported then. CUDA is generally more supported than OpenCL, but if you have a CUDA card, you can still take advantage of OpenCL enabled applications.

Moot point anyways as Adobe CC is so poorly optimized for GPU acceleration. GPU acceleration is only used when applying effects such as stabilizer or color correction. You can barely tell it's here in Lightroom CC, and god... does this application needs to be optimized.

If Adobe doesn't improve CC, I'll probably make the jump to FCPX as it totally obliterates Premiere CC in term of speed.

A non-functional core or CU isn't the only reason for disabling a part. Not all cores or CUs are capable of same performance|efficiency so even if you have 40 working CUs, you might disable the worst performing 4 if at least some set number don't meet a particular performance threshold.

It's likely that there will be a full Polaris 10 at some point, but it's mostly a factor of what kind of performance they want out of it and the process becoming mature enough to support the inventory numbers that they want. It may be that they want the 480X to be a 1070 competitor and right now they can't get enough 40 CU chips that can hit the clock speeds they need in order to have comparable performance.

Every cpu and gpu designer adds redundant circuitry to counter defects. This to make use of the all the available calculation power. For example with AMD, if they need 40 CU, they may design a unit with for example 44 CU.
But i think since AMD is on the new 14nm process, as an extra precaution they for now can also disable at least another CU (If it is really present). This gives the advantage of coming with a press release with x CU and harvest as many dies as possible. Increasing yield. I think that what everybody is thinking that there is a fully enabled polaris coming, is something that is going to happen. When the process is very good.
Not enough as a contestant for the GTX1070 and GTX180, but it was never meant for that. Although the future reviews will include all new gfx cards for a complete picture of what is available.

Just taking a quick glance I'm not seeing your claims for CUDA superiority. I'll have to give it a good read though. It's late here in NZ.

That doesn't change anything though, as now the full die is a 44 CU unit. Polaris 10 is likely a 40 CU part and the 480 is being sold with 36 active CUs, due to some combination of defects, efficiency, or marketing purposes. The only time you'll never sell an uncut die is if you're making such a massive chip that it's improbable to ever get a full die without some defect or part that has inferior performance.

Did NVidia ever manage to sell a fully enabled GF100?

I don't think they as a consumer card, but GF100 was also used for Tesla and that had a full die version of GF100.

It's pretty similar to GP100 where they have a massive die on a new process and the number of chips that have fully functional hardware or shouldn't have some part disabled for efficiency reasons are going to be low. Eventually yields will improve enough where they do sell an uncut GP100, but it's unlikely we'll see an uncut consumer version as by the time that's feasible, Volta should be ready.
