So, I wanted to see if I could come up with an estimate of how powerful the full Skylake Iris Pro is going to be. The existing Broadwell Iris Pro has 48 execution units. Skylake Iris Pro is going to have 72 EUs, a 50 percent increase.

Though it has been released for several months, it's not easy to find benchmarks where Broadwell Iris Pro is compared against decent entry-level GPUs. Anandtech compared it against the R7 250, which is like shooting fish in a barrel. No one buys that piece of crap. What we want to know is how it stacks up to low-end GPUs that people actually care about, like the GTX 750 Ti.

Fortunately, Tom's Hardware just ran a review of Star Wars: Battlefront where they tested it on just about every GPU, integrated or discrete, that's on the market today. This is just one game, but it is a AAA title that seems to be relatively vendor-agnostic, performing well on both AMD and Nvidia cards. At 1080p with Ultra settings and temporal AA, the Broadwell Iris Pro i7-5775C averaged 23 FPS. In comparison, the Gigabyte GTX 750 Ti OC averaged 35 FPS - a 52 percent improvement. On the red team, the Asus R9 270X DirectCU II averaged 46 FPS, exactly double Broadwell Iris Pro's showing.

Adding to this, R7 370 (Trinidad Pro, 1024 SPs) scores 36 FPS. The lower-clocked notebook versions of the GTX750 Ti and R7 370 are the GTX950M and R9 M390. Kudos to Intel if they can come close to the performance of these dGPUs (with a single 45W TDP chip) a few months before NVIDIA/AMD's 16/14nm lineup. Given that Apple is currently using R9 370X based on the old Cape Verde and there's nothing new @ AMD/NVIDIA's roadmap till Polaris/Pascal hits the market, IMHO they've got these options:
- Refresh the MBP 15'' in March with Iris Pro 580 (only), ditching the dGPU option - possibly introducing an external GPU solution (TB3) at the time or later.
- Refresh the MBP 15'' in March with Iris Pro 580 (only), introducing the dGPU version later @ mid-2016 (Polaris/Pascal).
- Refresh the MBP in March with Iris Pro 580 + optional (lower clocked) Geforce GTX950M. Not much faster than the iGPU (if at all) @ gaming but professionals might still benefit from it.
- Refresh the MBP in March with Iris Pro 580 + optional (lower clocked) Geforce GTX950M. New MBP 15'' @ H2-2016 with all the goodies, Iris Pro 580 + Polaris/Pascal dGPU.


If Intel's 10nm process doubles transistor density again, then conceivably Cannonlake Iris Pro could have 144 EUs, which would be about as powerful as a GTX 970. But at that point, it becomes seriously questionable whether 128MB of eDRAM is going to be enough to feed it.

Looks like Intel is adressing this by going 2x128MB @ Kabylake GT4e. What Cannonlake will use is a mystery though.



Congrats on the cite, Sweepr!

+1 to Sweepr as well here :thumbsup:

Thanks. ;)

Fascinating question why it took Intel so long to do this really - Apple must rate as a hugely important customer. Never mind :)

The new Vaio Z Flip is using 28Watt Skylake with a option for Iris HD 550. Finally.

Lisa Gade from MobileTechReview tested the Core i7-6567U model. As expected GT3e performs even better with more TDP headroom.

Skylake-U GT3e 28W Tested: Core i7-6567U (Vaio Z Flip)

This is the same processor that should be used by Apple for their top-of-the-line 2016 Macbook Pro 13''.

A little late on my part, but moar +1 for Sweepr!

Sweepr, +1 from me!

Keep on the informative work!

Thank you all, guys. :)
Hopefully it's a sign of more integration between front page and forums.
Some of the news about these chips were posted here before anywhere else.

Sweeper, don't let all that fame go to your head. Remember where you came from :D

LOL.

A little dissapointed with the performance in 3D given all the extra TDP room, but these are synthetics. We will have to see gaming results in game.

Iris 6100 (Macbook Pro 13'' Early 2015) vs Iris 550 (Vaio Z Flip)

- Cinebench R15 GPU OpenGL (Higher is better)
Iris Pro 5200 (65W): 48.63 FPS
Iris Pro 6200 (65W): 73.41 FPS
Iris 6100 (28W): 34.01 FPS
Iris 550 (28W): 61.45 FPS

- 3DMark 11 Performance Preset (Higher is better)
Iris Pro 5200 (65W): 2364
Iris Pro 6200 (65W): 3094
Iris 6100 (28W): 1828
Iris 550 (28W): 2830

Iris 550 (28W) is an impressive piece of tech, and I'm confident Apple's implementation (Macbook Pro 13'' 2016) will beat the scores of this new Vaio.

It'll do better against HD 520 and competitors in real world gaming and sustained load scenarios.

Iris 540 achieved 60% faster in benchmarks which only go for short duration but average gain in games turned out to be 30%.

Iris 550 should be closer to the 2800 score. I assume long-term performance to stay at 2500-2600 mark, which is pretty good. That means real world performance advantage over Iris 540 would be 30% while theoretical is at best 10%.

Now only if the real world pricing is cheap. You can't buy these without spending $1400 or more. And that's usually in US dollars. What about an Iris 550 in a $999 setup?

Surprisingly favourable review. Cinebench result didn't impress but it did well @ PCMark 8, graphics performance and battery life tests.

That s a misleading post as the i5/i7 scores are not performed with a 15W TDP at all as these have configurable TDPs..

If two cores and an uncore require 15W to perform 3.8 in CB 11.5 then a DT i7 would need less than 30W to perform 7.6 in this test, wich is not the case at all..

So please stop downplaying AMD by using fake TDP numbers for Intel chips, you could as well have branded Carrizo as 15W, it would have been much more adequate.

The fact that a thin and light (768 grams) 12'' tablet/convertible is beating the fastest Carrizo with 35W cTDP inside a (2.7 kilograms) 15.6'' laptop at multi-thread while demolishing it @ single-thread clearly shows how far behind AMD is when it comes to mobile. Unfortunately your imaginary numbers won't change this. ;)

That Asus Zenbook seems like a great package for someone who travels a lot or a student, and the price is fantastic. OTOH, makes you wonder why something like SP 3 has to be 200.00 more expensive without a keyboard, and why other ultrabooks have to be 1500.00 plus.

Edit: regarding the celeron, still betting eventually they will nerf bclock overclocking.

Still using the same numbers you dont understand how to read and add up already added numbers?

Yeah, ok. Whole world is being duped by Intel marketeers...what a joke.

Buy what you like but don't try to lead people into making bad purchases just because you don't like Intel.
