Haswell Prediction Poll: Sept? dGPU?

[Vanilla35]

A dGPU model would probably have a higher clock Haswell to make up for it, I'd think. It would also look "better" on paper, for those who chase nothing more than numbers.

I thought the Iris pro model has the highest possible CPU config available. And a dGPU would mean stepping down from that

If you scroll down to near the bottom (not sure if people have read this review or not) there are many review notes and performance statistics. 6.9/10 for graphics overall. That's a pretty paltry rating

That's where the dGPU would be a clear necessity.. but this blog had a couple charts I looked at for all the CPU versions..

There's no way they'd use a non-iris pro without a dGPU.. I agree with your note.

Well I thought that they would be using the Iris Pro comes with the 4950HQ and if they were to go with a dGPU they wouldn't be able to use the 4950HQ, but instead, lower configurations.

Yeah, I'm aware of that hah. My point is, the 4750HQ (or other variant of that level model) has HD 4600 graphics (making dGPU viable to be included with) but it also has a slower CPU. So doesn't that not make sense, since the dGPU model's CPU would technically be slower than the 4950HQ Iris pro model? Unless apple doesn't care about the maximum CPU speed in between their models.

If so, I think that eliminates the idea that they'd have a dGPU BTO option??

What about the 4900MQ? It's the most powerful of them all and comes with the 4600 GPU.

Oh, didn't know that then yeah I can see a dGPU option. In fact, if the 4900MQ is faster than the 4950HQ, then I think that'll definitely be the set up. 4950HQ Iris Pro set up for base model. And 4900MQ + dGPU for mid, and top tier 15" rMBP models.

Yeah the 4900MQ has 8MB L3 vs the Iris Pro model's 6MB as well, and max freq of 3.6 vs the 4950HQ at 3.4. Not significant to be sure, especially since the 4950HQ has that 128 MB eDRAM, but the 4900MQ with dGPU would definitely be a balanced match that the 4950HQ is with Iris Pro.

Doesn't the eDRAM only effect the gpu aspect (iris pro)?

Give me a 4900MQ with a 2gb nVidia 765M and I'm first in line.

I also think it's quite possible to fit the 765M in the macbook pro since they managed to get it in the Razer Blade which is a thin 14" laptop.

 

[GSPice]

Right - but I think it also has general purpose advantages. There are others much more qualified than myself that could chime in on how the Iris Pro integration has some unique benefit to the CPU operations.

That's exactly the machine I've been looking at for plausibility.

It's fine, it would just further exemplify that they might not keep that as a base if it contributes significantly enough to displace the low tier from the mid-high tier; assuming iris pro is low.

Same here. Would be everything I wanted, and everything I kind of expected...before iris pro.

 

[Mr MM]

There is no reason why they would use the MQ cpus, the HQ cpus are what wanted from intel, it doesn't matter about the clocks, they won't use it

the edram acts as a L4 cache, so it can be used for other things, that is if your app is coded correctly

 

[GSPice]

There is no reason why they would use the MQ

Glad it's all figured out then.

 

[Kirihuna]

I'll leave this here.

[Mr MM]

Glad it's all figured out then.

its a simple matter of logic, apple requests for intel better igpu performance years ago, and when they deliver they won't use it? right....

 

[ParanoidDroid]

I vote for October and No (with dGPU). I would say they are delaying since they are reducing in tickness and are having problems with excess heat. All the best, Rom

I think the delay is solely because intel isn't ready with Thunderbolt 2.

And yes, sadly I don't think we can expect dGPUs in futere MacBooks, so hopefully Skylake's iGPU will be a true dGPU replacement.

Intel also doesn't have the highest Iris 5200 CPU out yet.

I sincerely doubt that an iGPU will ever overtake a dGPU. Hopefully this gets Nvidia to do yearly releases in upgrades or a ticktock strategy instead of rebranding every other year.

 

[Vanilla35]

Soooooooo, the Intel 4960HQ, 4950HQ, and 4850HQ all come with Iris Pro, and at 47 TDP. Why would we assume that they can't also add a dGPU to that set up???

Because apple seems to be very enthusiastic about this iGPU thing. So why put so much work in getting the highest batch if iGPUs in the macbooks if they're gonna put a dGPU? If apple would put a dGPU, then they wouldn't care much about iGPUs.
Geekbench also showed that the 15 rMBP had no dGPU.

There might be a chance for apple to still offer a dGPU in some way though, as it's quite risky to release a high performance 'pro' laptop with only an iGPU. I'm sure they considered it and the iGPU should drive the rMBP smoothly for most tasks.

 

[NickPhamUK]

I couldn't care less, because I know for sure the coming rMBP 13" will only have dual-core chip with Iris 5100 at max. Those who're waiting for the 15" version, good luck .

Because they get top-bin components anyway. Iris pro isn't an exclusive product, other manufacturers will be utilizing it too. And there is already a laptop out with it. The geekbench could have shown the base model, and other higher end models have dGPUs. Could be wrong though. It seems very possible imo, but I'll have to wait for someone to comment on TDP to see if it's possible within the casing

 

[Serban]

so for base model dGPU 760M and for high model iris pro with 16G Ram and 512 SSD standard?

 

[mcarling]

I finally voted today. The latest rumors are pointing to a likely October launch, which I expect to probably be a silent update. There is still a chance for a launch in late September or early November or early 2014, but October looks likely.

A dGPU model would probably have a higher clock Haswell to make up for it, maybe an MQ, I'd think. It would also look "better" on paper, for those who chase nothing more than numbers.

The way to understand this is to think in terms of a budget. Intel have a budget of how many transistors they can reasonably put on one chip (roughly about a billion with current technology). That budget of transistors has to be allocated between making the CPU cores faster or more numerous or making the GPU faster or making the cache sizes larger (of course, in detail there are more complicated trade-offs, but these are the main trade-offs).

I sincerely doubt that an iGPU will ever overtake a dGPU.

I can remember people saying the same thing more than twenty years ago with discrete versus integrated floating point processors. ("I sincerely doubt that an FPU integrated into the CPU will ever overtake a dFPU.") It took only a few years after people started saying that until discrete FPUs were no longer being produced. The same will happen with GPUs. Increased integration is the basis of nearly all advances in integrated circuits.

I finally voted today.

I think Apple can finally start shipping then.

 

[GSPice]

Goodness at this point I'm fascinated to see what Apple does the Haswell rMBP. Whether or not there's a dGPU, Apple seems to be very pedantic in its design decisions. I can't wait to see what their plan is (or at least what they say their plan is).
