Haswell mobile IGP performance for gaming?

Have there been any independent benchmarks for Haswell integrated graphics yet?

What I understand so far is that there will be three different SKUs, the GT1 (for ULV processors?), GT2 and GT3, and the GT3 (the best one) will be available in some notebooks, and when paired with quad core CPU, Intel claims it will provide up to 200% the performance of the HD4000.

Also wondering whether there would be any advantage for the IGP with games with massive textures (for example, Skyrim with tons of texture mods, or idTech5 engine games), if you have a laptop with 8GB - 16GB system RAM. If I understand correctly, the integrated graphics makes use of the system RAM instead of VRAM; however, since most games are 32-bit applications and limited to max commit of around 3GB RAM, is the IGP making use of the remaining pool of RAM for textures or limited to a portion of that 3GB?

Crazy how quick these iGPU's are getting.

 

The IGP doesn't use RAM like that. The OS and IGP do not share the same RAM. The system RAM is divided between them and there is no overlap. The IGP has its share of your computer's RAM allocated to it, and the OS has its share of your computer's RAM allocated to it. The amount allocated to each can in some cases be dynamic, in which case the share of each changes while using the system.

 

Wow, that's great news! Is there a particular limit on how much the IGP can use, or is it affected by whether the application is 32-bit? I have 16GB, which, as you can imagine has been rather useless until now when it comes to gaming.

 

There are kind of 4 igpus in haswell

GT1 - budget line
GT2 - according to some leaks, it forms the grunt of most igpus, being called HD4600. It also comes with 20 EU
GT3 - the most powerful one, coming in with apparently 40EU
GT3 with edram - Only on select cpus this will come, it has a very wide bus edram in the cpu, some say that can be around 64mb to 128mb, so at first the igpu would use that edram than go for system which is much slower.

ram allocation is dynamic, the amount of ram is determined in a specified in a band. Games are 32 bit, so you are limited to how much ram you can use and that includes both the gpu ram and the system ram.

What I hope is that we have quads with the GT3 edram and that those are where they should be, in small form factors where power is needed

 

I'm really looking forward to seeing what production versions are capable of and how Apple will implement them. I'd love to drop down to a 13-inch system, but game performance on a Mac pretty much dictates keeping a 15.

 

My idea of a revamped rmbp 13 is going to be:

CPU: dual and quads, with possibly gt3 edram version (apple has nagged intel about this, so why not?)
RAM: 8 to 16gb, although I very much doubt that, I would expect 16gb in broadwell, because of DDR4
HDD: 2.5'' 7mm, there is space, I just need a cable

if that doesnt happen, there is always the possibility of getting the mLogic mLink or the sonnet echo express SE or the owc mercury helios and slap a 7750 in there, thats great gaming, while still portable and with little hassle.

 

I'm guessing the HD 4600 is going to be between the speeds of the GT 630M and GT 635M.

That's crazy.

 

hopefully this will put the heat on Nvidia and AMD to improve their mid/lower range graphics... competition is always good!

Also about time intel got serious about their iGPUs

 

On par with GT 650M? :O

Oh man my laptop isn't even a year old and it's already been caught up by an integrated GPU! At least NVIDIA still have far superior drivers.

 

Will depend on drivers and note he said without AA, this thing is going to want as fast ram as possible hooked up to it.

 

Nah it won't be close to the GT 650M. Like I said in another thread, the GT 540M/630M is often 2x faster than the HD 4000 at 768p, so they'll have to close that gap first.

 

Yeah the video was probably taken with a 30fps camera and then had YouTube compress it. I wouldn't read into it too much for gt3 performance.

 

They say Haswell will be 2x the performance of HD 4000. That will put it somewhere around the GT555M. Atleast for a bunch of games. Some games the 555M will lead, some the Haswell will lead. So in average that should put it around GT555M.

That is what I get from looking at the benchmarks and the Anandtech review. But we will see if Intel speaks the truth. Could be lower than 2x HD 4000

 

I serious doubt that haswell will be as fast as they are saying i think its going to be something like how AMD hyped up bulldozer

I think what we will see if them catch upto AMD and make something slightly faster then the HD 7660g and i really wanna see AMD's next APU so far the only igp's to impress me where AMD intels always felt meh.

Right now AMD has intel in the IGP and they got them pretty good. Im betting that this is just some smoke to put up to try and gain control back from some of the APU's. I mean i use to be flat out intel only but the last laptop i bought i only looked at A8's and A10's due to the fact of the IGP and never even considered a i5 or i7 for it.


My prediction its going to be at or about 10% faster then the HD 7660g. Maybe a little more if they do support for DDR3 1866+ but i dont see them putting that ram in systems since they have stock piles of DDR3 1600.

HD3000 to HD4000 was only about a 50% jump. In games it was less then that

CoD: Modern Warfare 3 (2011) – Medium Setting HD4000 HD 3000
45 fps 32 fps
Batman: Arkham City (2011) – Medium Setting 44 fps 31 fps
StarCraft 2 (2010) Medium Setting 33 fps 19 fps
Metro 2033 (2010) – Medium setting 23 13
Dirt 3 (2011) – Medium 42 fps 26 fps

I would love to buy into their marketing but i just cant. Intel display drives have always been subpar and on paper haswell looks nice but im only expecting it to catch up to AMD im really looking foreword to AMD's next APU's.



I mean we seen before where company's would mod drivers to show off what their products can do if Jesus blessed them. To me this just looks like so marketing to stur up a buzz about it to try and gain some market back from the APU's. Intel has dominated the market for the past few years but from what i been seeing the APU's have hit a nerve with them and i feel its going to be a look what this can do with out modded drivers and super code then when you get it it will be a oh you will only see a 5fps improvement over HD 4000 due to the games receiving updates sorry thanks for the money heres the middle finger.

 

Even the level of a 555m is still impressive for integrated graphics, and enough to run most games at 1080p. From what I can tell, the 555m is reportedly pretty close to my own 5830m, and I'm able to run every game I've ever tried at 1080p except Witcher 2.

In any case, I don't doubt that AMD can find some extremely specific settings configuration where it might be at least 2x HD4000. It's interesting to consider how the installed base of consumers with PCs capable of running games is expanding really quickly. Perhaps more console users will decide to try gaming on their laptops when they realize their integrated graphics can handle games.

 

Oh yes, if its similar to the GT555M thats very impressive indeed. Really cheap ultrabooks with GPU/CPU with just 47W.

 

one chip to rule them all!
