The Intel Ivy Bridge (Core i7 3770K) Review

Our final game, Civilization V, gives us an interesting look at things that other RTSes cannot match, with a much weaker focus on shading in the game world, and a much greater focus on creating the geometry needed to bring such a world to life. In doing so it uses a slew of DirectX 11 technologies, including tessellation for said geometry, driver command lists for reducing CPU overhead, and compute shaders for on-the-fly texture decompression. There are other games that are more stressful overall, but this is likely the game most stressing of DX11 performance in particular.
Unfortunately this ends up being the worst showing for Ivy Bridge. It's ever so slightly trailing the Radeon HD 5450 here, never mind the faster dGPUs or Llano. As we'll see in our compute benchmarks DirectCompute performance plays a large part here, but even then it doesn't explain why CivV performance is quite this low. As a result Llano is once again well in the lead, with Ivy Bridge only reaching some 30% of Llano's performance.

I'll keep my 2600K.....just kidding

I hope you give AMD even more praise when Trinity is released Anand. IMO you way overblew how great Intels igp stuff. Its their 4th gen that can't even beat AMDs first gen.Just my opinion :p

As much as I like the idea of decent Skyrim framerates on every laptop, and even though I find the HD4000 graphics an interesting read, I couldn't care less about it in my desktop. Gamers will not put up with integrated graphics - even this good - unless they're on a tight budget, in which case they'll just get Llano anyway, or wait for Trinity. As for IVB, why can't we have a Pentium III sized option without IGP, or get 6 cores and no IGP?Kjella - Tuesday, April 24, 2012 - link
Strategy, they're using their lead in CPUs to bundle it with a GPU whether you want it or not. When you take your gamer card out of your gamer machine it'll still have an Intel IGP for all your other uses (or for your family or the second-hand market or whatever), that's one sale they "stole" from AMD/nVidia's low end. Having a separate graphics card is becoming a niche market for gamers. That's better for Intel than lowering the expectation that a "premium" CPU costs $300, if you bring the price down it's always much harder to raise it again...Samus - Tuesday, April 24, 2012 - link
As amazing this CPU is, and how much I'd love it (considering I play BF3 and need a GTX560+ anyway) I have to agree the GPU improvement is pretty disappointing...After all that work, Intel still can't even come close to AMD's integrated graphics. It's 75% of AMD's performance at best.

There is actually a good reason for both AMD and Intel to keep a GPU on their CPUs no matter what. That reason is OpenCV. This move makes the assumption that OpenCV or programming languages like it will eventually become mainstream. With a GPU coupled to every CPU, it saves developers from writing two sets of code to deal with different platforms.froggr - Saturday, May 12, 2012 - link
OpenCV is Open Computer Vision and runs either way. I think you're talking about OpenCL (Open Compute Language). and even that runs fine without a GPU. OpenCL can use all cores CPU + GPU and does not require separate code bases.OpenCL runs faster with a GPU because it's better parallellized.

Maybe we could actually see some hard numbers before heaping so much praise on Trinity??I will be convinced about the claims of 50% IGP improvements when I see them, and also they need to make a lot of improvements to Bulldozer, especially in power consumption, before it is a competitive CPU. I hope it turns out to be all the AMD fans are claiming, but we will see.

Sure, Llano gives good gaming performance. But it's pretty much at Athlon II X4 CPU performance.
