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 see them just killing off the 13" MacBook Pro entirely, and upgrading the SSD base size to 256GB. There's little reason for the Pro to live on anymore when the Air is far superior in everything except for CPU. Reply

    Really... the Air's screen is terrible. Plus Air is basically not user upgradeable. Reply

    Yeah, I view mine as a consumable. And I love it. Reply

    That would be a shame, even without the optical drive they could differentiate the 13" pro from the Air with the mentioned 35w quad core CPU, or a discreet GPU in all the space they saved from ditching the ODD, and have more space for battery to offset it. Reply

    If I'm buying a system for onboard GPU gaming, I'm going AMD. If I'm buying a system for cpu performance with overclocking, I'm buying Sandy Bridge. I'm not sure what the point of this launch is. Reply

    Notebooks/ultrabooks and debugging the new process node. Reply

    I've seen so many negative comments like this about Ivy Bridge all over the web... so I'll respond to them all here:

    I'd rather have higher energy efficiency and stability (and less noise), which comes with running at stock voltage/clock speeds. I am not alone there... Plus with turbo boost, why bother OCing, when it has the thermal headroom, it boosts the clock...

    If you think that you can find a significantly better sweat spot of performance, power consumption, and reliability/lifespan of the average high-end (K) CPU from intel, then I have to call BS on that. If you agree that intel knows their cpus better than you, but are purposely under-clocking them (the highest clocked models), then I would ask why.

    I may say that given significantly more exotic/larger/louder coolers, maybe you can dissipate more heat than the processors were designed to dissipate, and you have some headroom to raise the voltage, which may yield higher stable frequencies, but keep in mind power is roughly proportional to voltage^2, so energy efficiency goes out the window real fast...

    I'm not saying no one should play around with their CPUs, have fun... but to say ivy bridge is pointless just because you can't over-volt/over-clock it to the same extent as sandy bridge is foolish when it's clearly a significant step forward, and the best solution for the vast majority x86 PCs.

    For those of us who want an energy efficient, high performance computer, some variant of ivy bridge will be the best option, probably until haswell/2013.

    Thanks intel, and thanks Anand for the review.

    But it's really not that much more efficient. In fact at idle, the difference is negligible by all benchmarks I've seen, which for most users is the most important area. At full power, a difference of 25 watts is practically nothing given how much time most cpu's are spent at that load. It really shouldn't affect power supply sizing either. I'm just talking about desktop usage here, we don't really have a good look at the notebook chips yet.

    I'm not sure what Intel thinks it's pulling by calling this "tick+" instead of a regular "tick". I don't see anything here that's really that appealing. If helps Intel "debug the process node for 22nm", that's great for Intel, but it doesn't sway me as a consumer to buy one.

    Idle power quickly hits a limit based on everything else in the system. It's hardly surprising that the highly efficient Sandy Bridge does just as well at idle as Ivy Bridge. Power gating allows Intel to basically shut down everything that's not being used, and the result is that low loads have pretty much hit their limits. What's impressive is the big drop in power use under heavier loads.

    As for the "tick+", it's all in the GPU. They went from DX10 12EU in SNB to DX11 and 16EU in IVB. As a percentage of total die size, the GPU in IVB is much larger than the one in SNB. But as Anand notes, we still would have liked more (e.g. a 24 EU GT3 would have been awesome for IGP performance).

    Marginal improvement over Sandy Bridge that can be compensated for by SB's significantly better overclocking ability. Why so much praise for the IGP when 95% of desktop users don't care AND its still vastly inferior to Llano? With so much focus on mobile I'm not even sure why they bothered releasing a high-end desktop SKU Reply
