Final Words

Based on these early numbers, Ivy Bridge is pretty much right where we expected it on the CPU side. You're looking at a 5 - 15% increase in CPU performance over Sandy Bridge at a similar price point. I have to say that I'm pretty impressed by the gains we've seen here today. It's quite difficult to get tangible IPC improvements from a modern architecture these days, particularly on such a strict nearly-annual basis. For a tick in Intel's cadence, Ivy Bridge is quite good. It feels a lot like Penryn did after Conroe, but better.

The improvement on the GPU side is significant. Although not nearly the jump we saw going to Sandy Bridge last year. Ivy's GPU finally puts Intel's processor graphics into the realm of reasonable for a system with low end GPU needs. Based on what we've seen, discrete GPUs below the $50 - $60 mark don't make sense if you've got Intel's HD 4000 inside your system. The discrete market above $100 remains fairly safe however.

With Ivy Bridge you aren't limited to playing older titles, although you are still limited to relatively low quality settings on newer games. If you're willing to trade off display resolution you can reach a much better balance. We are finally able to deliver acceptable performance at or above 1366 x 768. With the exception of Metro 2033, the games we tested even showed greater than 30 fps at 1680 x 1050. The fact that we were able to run Crysis: Warhead at 1680 x 1050 at over 50 fps on free graphics from Intel is sort of insane when you think about where Intel was just a few years ago.

Whether or not this is enough for mainstream gaming really depends on your definition of that segment of the market. Being able to play brand new titles at reasonable frame rates as realistic resolutions is a bar that Intel has safely met. I hate to sound like a broken record but Ivy Bridge continues Intel's march in the right direction when it comes to GPU performance. Personally, I want more and I suspect that Haswell will deliver much of that. It is worth pointing out that Intel is progressing at a faster rate than the discrete GPU industry at this point. Admittedly the gap is downright huge, but from what I've heard even the significant gains we're seeing here with Ivy will pale in comparison to what Haswell provides.

What Ivy Bridge does not appear to do is catch up to AMD's A8-series Llano APU. It narrows the gap, but for systems whose primary purpose is gaming AMD will still likely hold a significant advantage with Trinity. The fact that Ivy Bridge hasn't progressed enough to challenge AMD on the GPU side is good news. The last thing we need is for a single company to dominate on both fronts. At least today we still have some degree of competition in the market. To Intel's credit however, it's just as unlikely that AMD will surpass Intel in CPU performance this next round with Trinity. Both sides are getting more competitive, but it still boils down to what matters more to you: GPU or CPU performance. Similarly, there's also the question of which one (CPU or GPU) approaches "good enough" first. I suspect the answer to this is going to continue to vary wildly depending on the end user.

The power savings from 22nm are pretty good on the desktop. Under heavy CPU load we measured a ~30W decrease in total system power consumption compared to a similar Sandy Bridge part. If this is an indication of what we can expect from notebooks based on Ivy Bridge I'd say you shouldn't expect significant gains in battery life under light workloads, but you may see improvement in worst case scenario battery life. For example, in our Mac battery life suite we pegged the Sandy Bridge MacBook Pro at around 2.5 hours of battery life in our heavy multitasking scenario. That's the number I'd expect to see improve with Ivy Bridge. We only had a short amount of time with the system and couldn't validate Intel's claims of significant gains in GPU power efficiency but we'll hopefully be able to do that closer to launch.

There's still more to learn about Ivy Bridge, including how it performs as a notebook chip. If the results today are any indication, it should be a good showing all around. Lower power consumption and better performance at the same price as last year's parts - it's the Moore's Law way. There's not enough of an improvement to make existing SNB owners want to upgrade, but if you're still clinging to an old Core 2 (or earlier) system, Ivy will be a great step forward.

    "Nice to see AMD winning where it actually matters for most consumer applications."

    I dont see how you can look at these (or any) benchmark and call it a win for AMD. Intel is smoking them. A few useless integrated graphics benchmarks and you call it a win? Hey, I hear RIM is looking for a new PR rep, they could really use a guy like you. ;)

    IGP performance is nice, but no comments about the subjective quality, i have seen side to side HD Graphics 2000 vs Radeon IGP and the graphics quality was night and day, with the radeon being the day...
    I dont know whats needed to do properly integrated graphics, but seems intel still lacks...

    Yes,people standard are different. For gamer intel IGP might suck, but it's more than enough for me.If I buy Llano, the graphic core might be just a wasted silicon because I don't really do gaming.Buy 1 if you only need 1 Reply

    OK, DirectCompute is supported by the GPU: we see the fluid benchmark in review.

    But GPU is OpenCL 1.1/1.2 compliant?

    You mentioned in your intro about the Intel-Apple exclusivity agreement being up and Apple constantly pushing Intel for better GPU performance. Do you think Ivy Bridge has made sufficient gains in GPU performance to keep Apple on board? Have you had a chance to test Ivy Bridge's IGP OpenCL performance since that seems like a particular area of interest for Apple? Reply

    I think its sure that they will. They chose a weaker CPU in favour of a stronger IGP (9400 and Core 2 Duo) before, but now we're at a point where the HD4000 would be more than adequate for Mountain Lion and probably onwards, plus Intel is way ahead with 22nm and the resulting power draw as well as CPU performance, and I think Apple uses Quicksync for Airplay which is Intel-only.

    It really depends on your workload.

    Personally I need CPU grunt far more than GPU grunt, which I suppose means I wouldn't even strictly need the 4K class GPU.

    But it's 'free' so I'll take it. :)

    The top end models which would probably be paired with a discreet card get decent integrated graphics, while the low end ones which will probably be standalone get cut down IGPs. Odd. If anything I think on the top end people would want models with less space used on integrated graphics with that headroom used for higher clocks or lower prices, even the cut down IGPs can do Quicksync.

    Also a suggestion for the full review, we know pretty much to expect from the HD4000 performance wise, but what about image quality? AMD and Nvidia improved things generation after generation, and I doubt Intel got it right with their first or second serious foray into lower-midrange graphics.

    Apple?
    If IGP supports OpenCL as well as DirectCompute there's no more reason for a AMD APU for pro users not gamers.

    Seriously, this is too much, its fine that you have an opinion and I might not have a problem with it if you posted it once, but you post the same damn thing on every article whether its related or not and usually multiple times, someone just please do us all a favour and ban this guy and delete his comments?
