BioShock: Infinite

Bioshock Infinite is Irrational Games’ latest entry in the Bioshock franchise. Though it’s based on Unreal Engine 3 – making it our obligatory UE3 game – Irrational had added a number of effects that make the game rather GPU-intensive on its highest settings. As an added bonus it includes a built-in benchmark composed of several scenes, a rarity for UE3 engine games, so we can easily get a good representation of what Bioshock’s performance is like.

BioShock: Infinite

Both the 650M and desktop GT 640 are able to outperform Iris Pro here. Compared to the 55W configuration, the 650M is 32% faster. There's not a huge difference in performance between the GT 640 and 650M, indicating that the performance advantage here isn't due to memory bandwidth but something fundamental to the GPU architecture.

In the grand scheme of things, Iris Pro does extremely well. There isn't an integrated GPU that can touch it. Only the 100W desktop Trinity approaches Iris Pro performance but at more than 2x the TDP.

BioShock: Infinite

The standings don't really change at the higher resolution/quality settings, but we do see some of the benefits of Crystalwell appear. A 9% advantage over the 100W desktop Trinity part grows to 18% as memory bandwidth demands increase. Compared to the desktop HD 4000 we're seeing more than 2x the performance, which means in mobile that number will likely grow even further. The mobile Trinity comparison is a shut out as well.

    Haswell ULT GT3 (Dual-Core+GT3) = 181mm2 and 40 EU Haswell GPU is 174mm^2.
    7mm^2 for everything else except GT3?

    " An Ultrabook SKU with Crystalwell would make a ton of sense, but given where Ultrabooks are headed (price-wise) I’m not sure Intel could get any takers."

    They sure seem to be going up in price, rather than down at the moment...

    Intel has once again made their naming so confusing that even their own marketing weasels can't get it right. Notice that the Intel slide titled "4th Gen Intel Core Processors H-Processors Line" calls the graphics in the i7-4950HQ and i7-4850HQ "Intel HD Graphics 5200" instead of the correct name which is "Intel Iris Pro Graphics 5200". This slide calls the graphics in the i7-4750HQ "Intel Iris Pro Graphics 5200" which indicates that the slide was made after the creation of that name. It is little wonder that most media outlets are acting as if the biggest tech news of the month is the new pastel color scheme in iOS 7. Reply

    The peak theoretical GPU performance calculations shown are wrong for Intel's GFLOPS numbers. Correct numbers are half of what is shown. The reason is that Intel's execution units are made of of an integer vec4 processor and a floating-point vec4 processor. This article correctly states it has a 2xvec4 SIMD, but does not point out that half is integer and half is floating-point. For a GFLOPS computation, one should only include the floating-point operations, which means only half of that execution unit's silicon is getting used. The reported computation performance would only be correct if you had an algorithm with a perfect mix of integer & float math that could be co-issued. To compare apples to apples, you need to stick to GFLOPS numbers, and divide all the Intel numbers in the table by 2. For example, peak FP ops on the Intel HD4000 would be 8, not 16. Compared this way, Intel is not stomping all over AMD & nVidia for compute performance, but it does appear they are catching up. Reply

    I heard that Intel 22nm process equals TSMS 26nm, so the difference is not that much. Reply

    I think Intel could push their yield way up by offering 32MB and 64MB versions of Crystalwell for i3 and i5 processors. They could charge the same markup for the 128, but sell the 32/64 for cheaper. It would cost Intel less and probably let them take even further market share from low-end dGPUs. Reply

    It is funny how a non-PC company changed the course of Intel forever for the good. I hope that Intel is wise enough to use this to spring-board the PC industry to a new, grand future. No more tick-tock nonsense arranged around sucking as many dollars out of the customer as possible, but give the world the processing power it craves and needs to solve the problems of tomorrow. Let this be your heritage and your profits will grow to unforeseen heights. Surprise us! Reply

    I wonder where this is going. Yes the multi core and cache on hand and graphics may be goody, ta.
    But human interaction in actual products?
    I weigh in at 46kg but think nothing of running with a Bergen/burden of 20kg so a big heavy laptop with ingratiated 10hr battery and 18.3" would be efficacious.
    What is all this current affinity with small screens?
    I could barely discern the vignette of the feathers of a water fowl at no more than 130m yesterday, morning run in the Clyde Valley woodlands.
    For the "laptop", > 17" screen, desktop 2*27", all discernible pixels, every one of them to be a prisoner. 4 core or 8 core and I bore the poor little devils with my incompetence with DSP and the Julia language. And spice etc.

    P.S. Can still average 11mph @ 50+ years of age. Some things one does wish to change. And thanks to the Jackdaws yesterday morning whilst I was fertilizing a Douglas Fir, took the boredom out of a another wise perilous predicament.

    Hello,
    Look, 99% of all the comments here are out of my league. Could you answer a question for me please? I use an open source 3d computer animation and modeling program called Blender3d. The users of this program say that the GTX 650 is the best GPU for this program, siting that it works best for calculating cpu intensive tasks such as rendering with HDR and fluids and other particle effects, and they say that other cards that work great for gaming and video fall short for that program. Could you tell me how this Intel Iris Pro would do in a case such as this? Would your test made here be relevant to this case?
