Haswell GT3 rating guess?

[AlexAL]

If "The GT3 is running "Skyrim" at 1920x1080 resolution with High settings, while the HD 4000 GPU next door is running the same game at the same frame rate, but at Medium settings and a 1366x768 resolution" and the GT3 has "2x the graphics performance of Ivy Bridge", what present mobile GPU would the GT3 be closest to?

Here is a link to the Ivy Bridge HD 4000 from notebookcheck.net.

I seriously have my doubts that the GT3 can actually do that. Intel themselves said only double the performance.

Well, 1920x1080 is twice the amount of pixels as 1366x768 (1.97 times actually) so maybe it is possible

Note the "High detail" at 1080 vs the "Medium detail" at 768. I doubt it's possible, but fairplay to intel if they can pull it off!

Skyrim is really not a very demanding game. The PC port has little over what the console versions have -- the biggest difference is better texture detail. Given that GT3 has much better memory bandwidth, I find it entirely believable that on this load it can do that well.

Plus, the GT3 doubles all of the other internals as well, not just the shader cores. I find this entirely believable so long as the memory bandwidth is good. I wonder what Intel is realistically doing in that area.

AMD is going to have some serious iGPU competition with Haswell/Broadwell.

I agree it is more demanding on the CPU than the GPU; Bethesda games have always been that way.

I expect the GT3 in a best-case scenario will compete with GT-640 or a Radeon HD6670 (discrete cards). There probably isn't an iGPU that competes with it out right now.

It'll be interesting to see what intel did to alleviate the bandwidth problem

Unfortunately, Skyrim is one of the titles where HD4000 was already competitive with AMD's offerings. It would have been far more telling if they'd demonstrated comparative performance between IVB GT2 and HSW GT3 in Civ V or one of the other games that appear to be hitting bottlenecks in HD4000. Because that's the real question with HSW - if those bottlenecks are removed, the games where Intel's currently behind could see a 3-4x performance improvement.

Besides the wild claims to get Netburst to 10ghz and beyond (marketers only...) Intel is pretty upfront and honest about claims they are demonstrating. I would be suprised if this was a 'wood screw' type smoke and mirrors. Looks impressive, for sure. As other have pointed-out, GT2 was already decent in skyrim at 1366x768 @ medium settings (30+fps). It's great to see integrated video get to the point where folks can run some decent titles at acceptable framerates.

 

[AlexAL]

Great comments. I have doubts Intel can pull off something amazing, but at the same time hope that some day they will (say, run games at med at native res).

Somewhere around HD 6670.

 

[VirtualLarry]

Of course, this is all moot, if only the mobile CPUs have GT3.

It would be nice to get a desktop CPU that has GT3, without having to pay the price premium for the higher-end unlocked K chips.

I would prefer Intel to spend more effort on improving IPC. I hate paying for iGPUs that I don't use. I have discrete GPUs.
