Metro 2033

The heaviest test we'll show in this suite, Metro 2033 still requires a discrete GPU for reasonable performance. That being said, it's still an interesting measure of how much more GPU horsepower exists in Ivy Bridge:

Here the Llano gap shrinks to about 13 - 25% depending on the resolution/quality settings. AMD still has the clear advantage in GPU performance, but Intel does step closer. The performance advantage over Sandy Bridge ranges from 20 - 40%. With these sorts of numbers it's clear why Intel views Ivy Bridge as being a tick+. Generational performance improvements on the CPU side generally fall in the 20 - 40% range. As you've just seen, Ivy Bridge offers a 7 - 15% increase in CPU performance over Sandy Bridge - making it a bonafide tick from a CPU perspective. The 20 - 40% increase on the graphics side is what blurs the line between a conventional tick and what we have with Ivy Bridge.

    Thankfully the comments of a certain troll were removed so mine no longer makes sense, for any future readers. Reply

    Just like how overclocking a Pentium 4 resulted in it beating an Athlon 64 and had lower power consumption to boot-- oh wait. Reply

    That's a stupid comment only a stupid fanboy would make AMD is way ahead of Intel in the graphics department and is very competitive with Intel in the mobile segment now. Reply

    Your comments would do nothing to inform regular readers of sites like this, we already know more. So please, can it. Reply

    Not what I asked little troll. Give a source that says Apple will get a special HD4000 like no other. Reply

    What are you talking about? As long as AMD has a better iGPU there is plenty of reason for them to be viable choice today. And if gaming iGPU performance holds on against Intel there is more than just hope of them getting back in the game in terms of high performance comput tomorrow. Reply

    I'm pretty sure even 16x AF has a sub 2% performance hit on even the lowest end of todays GPUs, is it different with the HD Graphics? If not, why not just enable it like most people would, even on something like a 4670 I max out AF without thinking twice about it, AA still hurts performance though. Reply

    AF has greater performance impact on low end GPUs. Typically its about 10-15%. It's less on the HD Graphics 3000, only because their 16x AF really only works at much lower levels. It's akin to having option for 1280x1024 resolution, but performing like 1024x768 because it looks like the latter.

    If Ivy Bridge improved AF quality to be on par with AMD/Nvidia, performance loss should be similar as well.

    Hmm I did not know that, what component of the GPU is involved in that performance hit (shaders, ROPs, etc)? My card is fairly low end and 16x AF performs nearly no different than 0x. Reply

    AF requires more samples in cases of high anisotropy so I guess the TMU load increases, which may also increase bandwidth requirements since it could force higher LOD in these cases. You'll only see a performance difference if the AF causes the scene to be TMU/bandwidth limited instead of say, ALU limited. I'd expect this to happen more as you move up in performance, not down, since ALU:TEX ratio tends to go up along the higher end.. but APUs can be more bandwidth sensitive and I think Intel's IGPs never had a lot of TMUs.

    Of course it's also very scene dependent. And maybe an inferior AF implementation could end up sampling more than a better one.
