Intel Iris & Iris Pro Graphics: Haswell GT3/GT3e Gets a Brand

[IntelUser2000]

You are right. But even better is to compare just graphics scores.

Hmm, according to Intel's graph here: http://images.anandtech.com/doci/6926/Screen%20Shot%202013-05-01%20at%205.37.22%20PM.png

The 4900MQ should have 3DMark11 Graphics Suite score of 1.6x the 3840QM.

From notebookcheck the highest HD 4000 score is 684. 1.6x that is only 1094.

http://benyouhuifile.it168.com/forum/201304/28/175357fou6r336sfvcf68f.png.thumb.jpg

But the tested 4930MX gets 1274 points, which is 86% better than the best HD 4000 score, or 16% better than expected.

That means driver should have played a part in it. If that follows to the Haswell GT3e part, then the Graphics Suite score may reach 2000. Performance score would end up being at 2200 points, and the 55W cTDPup version would get 2350 points.

3dmark11 from a mobile high-end GT2.

This score is better than A10-4600M.

Intel Mobile HD4000 Graphics Score = ~600
AMD A10-4600M Graphics Score = 1055
Intel Haswell GT2 Graphics Score = 1274 ????

GT2 has double(2x) the Graphics score of HD4000 in 3D Mark 11 ???

From Intel's Slide GT2 only has 50% more performance in 3D Mark 11 while GT3 has 2.5x and GT3e 2.6/2.7x ??

If you use the 'Performance' (802 max) rather than 'Performance GPU' (684 max) score from NotebookCheck you end up with a score of 1283 which sounds about in line with what was expected.

I'm gonna disagree with this.

I just don't see Apple's web-pages marketing the 2013 15" rmbp with:

We've increased battery life and built a cooler running macbook, but our graphics performance is down by 20%... AND, our top of line machine has lost CUDA in pro-applications...

Apple is the inventor of OpenCL. They don't use CUDA.

From Intel's Slide GT2 only has 50% more performance in 3D Mark 11 while GT3 has 2.5x and GT3e 2.6/2.7x ??

HD4000 is faster:
http://www.notebookcheck.com/Kurzte...erung-der-Intel-HD-Graphics-4000.79664.0.html

HD4600 (1350 MHz): 1418 complete score (the leaked one)
HD4000 (1350 MHz): 880 complete score
-> 1.61x speedup at the same clock

In the slide the mentioned speedup is about 1.6x at 1300 MHz for both, the 3840QM and the 4900MQ. So it fits almost perfectly.
If you take the GPU scores only, it's 1.7x (1274 vs 748). Also close.

 

[AtenRa]

Intel Slide measures 3840QM (1300MHz iGPU) as base (1).

According to your HD4000 link 3840QM gets 852 total score and 728 Graphics score.

Total score 852 + 60% = 1363
Graphics score 728 + 60% = 1164

From the leaked score
1418 is 66,4% faster than 852 = Total score
1274 is 75% faster than 728 = Graphics score

So, which one is it ?? Ill say they measured Total score.

GT2 isn't the high end. It isn't even Iris. The high end are HD5100, 5200, iris and iris pro. Those will not be available (BGA only) on desktop and you won't see benchmarks anytime soon.

I know. For GT2 it is high-end. With 1350 Mhz this is the highest clocked GT2 variant.

Intel Mobile HD4000 Graphics Score = ~600
AMD A10-4600M Graphics Score = 1055
Intel Haswell GT2 Graphics Score = 1274 ????

GT2 has double(2x) the Graphics score of HD4000 in 3D Mark 11 ???

From Intel's Slide GT2 only has 50% more performance in 3D Mark 11 while GT3 has 2.5x and GT3e 2.6/2.7x ??

You should compare with a comparable mobile Ivy Bridge high-end GT2.


http://www.notebookcheck.com/Kurzte...erung-der-Intel-HD-Graphics-4000.79664.0.html

Ivy Bridge GT2 1350 Mhz scores 748....means HSW GT2 1350 Mhz scores 70% faster at the same clock. Keep in mind the current driver is faster than last year, so the 60% from the Intel slide perfectly fits.

 

[boxleitnerb]

The iGPU from the leaked score runs at 1350 MHz, not 1300. And don't forget drivers which may account for a small difference as well.
The slide says "graphics" for 3DMark Vantage and 3DMark 11, but not for 3DMark06. So I suspect they really mean the GPU subscore only.

I find these results remarkable. Intel will most likely almost tie the fastest mobile Richland iGPU and win with GT3 and GT3e. They have closed the performance gap completely and even surpassed AMD in certain segments in only 3 generations.

The Intel Slide shows Core i7 3840QM as base score 1. Core i7 3840QM is a 45W TDP with HD4000 at base 650MHz and Turbo up to 1300MHz.
From this link (Mobile HD4000 performance) Core i7 3840QM gets 852 total 3D Mark 11 Score and 728 Graphics Score. (Second line in the table bellow )

Also, Intel Slide is the latest one and most probable they have used the latest drivers. So the 60% improvement must be for the total 3D Mark score because Graphics performance (728 to 1274) is higher at 75%.

The leaked i7-4930MX clocks with 1350 Mhz! You cannot use a 1300 Mhz score. You have to use the 1350 Mhz score. The new driver scores ~+5% higher in 3dmark11. 60% must be for the graphics score, exactly what they claimed in the slide.

Why use 1350MHz when the Core i7 3840QM which Intel uses as the base in its slide has 1300MHz HD4000 ??

 

[AtenRa]

Ahh ok got it, you mean that HD4000 at 1300MHz got another 5% from the driver and raised from 728 Graphics score to ~765. Then a 60% increase will get it to 1224, close enough to the leaked Graphics score of 1274.

 

[mikk]

Why use 1350MHz when the Core i7 3840QM which Intel uses as the base in its slide has 1300MHz HD4000 ??

Intel slide:

i7-3840QM 1300 Mhz GT2
i7-4900MQ 1300 Mhz GT2 ~x1.6

Leak:

i7-4930MX 1350 Mhz GT2

If you want to compare the speedup from i7-4930MX you have to use an Ivy Bridge mobile Quadcore with 1350 Mhz. Otherwise you can't compare the speedup.

 

[AtenRa]

Heh, i thought 4930MX was the same as 4900MQ, my bad

 

[Sweepr]

With HD Graphics 5000 inside Haswell ULV (15W) likely bringing higher graphical performance than the standard voltage HD4000 I'm guessing some manufecturers will bring high PPI (Retina like) displays to premium ~11.6 inch Ultrabooks later this year.

 

[Fjodor2001]

I wonder what the performance increase of the GT3e would be if it would not have had the 128 MB eDRAM? Is it memory bandwidth bottlenecked to such a degree that it was essential to add it to achieve any reasonable performance improvement?

 

[ViRGE]

GT3e without eDRAM would be GT3. So we'll know soon enough. But virtually all iGPU solutions are memory bandwidth bottlenecked to some degree.

In theory could be a bit better than an a10. Intel generally has a better performing memory controller.

starting to get really tired of reading about how great haswell's graphics are when everyone is using gt3e as comparison, rather than the reality of what most will be getting..gt2/3

 

[MightyMalus]

4770R looks interesting...but its a "desktop" gt3e? Weren't desktop gt3 haswell chips gonna be AIO and of the sort only? Not actually upgradable.

No, the rumor was/is that Broadwell (after Haswell) could be soldered into the socket.

I personally feel the same way about Trinity (but with A10 vs A8/6/4 instead).

 

[MightyMalus]

No, well maybe it was a rumor. But I mean Haswell GT3(just edited above...) was only getting on the desktop AIO devices and things like that. Like look at the 4770K, don't have GT3...that's what I mean.

Ah, okay, I see what you mean. Yeah, I heard the same thing about the GT3e chips--only mobile chips can get the eDRAM. But I think some desktop chips have the GT3, at least (though weaker ones are more common since the enthusiast need for an APU compared to CPU+dGPU is pretty low right now).

I'm personally a little disappointed that they didn't put it on a Pentium or something to spur more competition with Trinity.

Broadwell will bring GT4, maybe there will be more desktop GT3 models available by then.

 

[Sleepingforest]

Just some more information on Broadwell from TechPowerUp:

Evidently, you can expect both an LGA1050 and a BGA (where pins are replaced with solder, effectively locking you in to one CPU/mobo combo) version of Broadwell.
