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.

    Most players who game at 1920x1080 also have graphics cards that cost more than $100. That's not what this was testing. Reply

    Man you won't believe the difference :)

    Get an SSD with that.

    You're going to seriously start wondering why you didn't upgrade sooner. Just don't hurt yourself too much when you slap your own face. Tech has advanced astronomically in the last 10 years.

    Heck, I'm pretty sure the iPad 2 is faster than your Northwood Pentium 4.

    uhh.. i don't think that's true. graphics intensive applications are not the only ones that benefit from fast CPUs. Reply

    Where does Charlie claim to be biased?

    But i agree, this sacred, aura, "this is not sanctioned by Intel" is a pain to read. It makes thesse articles a little bit difficult to start reading :)

    But how profitable, and how good a business do you have if you dont have "good conections"? - charlie uses his for underhand information, anand his to get info before the others. Its very obvious for us to interprete Anands article because we know the obvious, - it have to be profitable for both anand and Intel. But what about Charlie, what is the motives for the people leaking info to him? - its not quite so obvious and transparrent.

    "Sure, he was comparing Intel graphics to Intel graphics, except he wasn't, because he himself threw Llano in there to compare."

    By the same token, if he had not included Llano results people would be wondering where they were and complaining that they weren't included. Puts Anand in a catch 22 when deciding whether or not to include Llano.

    There is validity to the complaint about the numbers being incorrect. Those should be looked at and corrected. Glossing over the results and no mention of Llano being more capable, again, this was mainly to compare Intel v Intel in a preview of their new chip and improvements they've made since last gen. Sure, he could've been more thorough with the AMD v Intel side, but that's not really what this article was about. We could also go to a steakhouse and complain there's not a large vegetarian meal selection too.

    it doesn't really matter if the igp isn't that great most people don't buy them for their graphics power.I get the feeling that maybe intel is just putting them out there to keep it's base solid against AMD,Not that it needs it and i'm an amd fan. i found something the other day that will possibly change how tomorrows processors will use light instead of electricity.

    ...hi everybody.

    I'm an electrical engineer, doing intensive "spice" simulations.
    I want to know if, as it requires a lot of floating point calculations, does it worth to wait for Ivy Bridge instead of buying right now a laptop with a quadcore Sandy Bridge? I expected Ivy Bridge for March and i've been waiting since last december :(.
    To buy now would be very comfortable, as i'm in the simulaiton phase of my project. To buy later, I believe, would make more sense in term of pure performances . But how much sense is the question....

    Thanks for sharing

    PS (another thing is also theuse of 1600 memory instead of 1333, which might be doing it for another software I use)
  • arno - Friday, March 9, 2012 - link

    I wonder how IvyBridge perform in term offloating point calculations as I do intensive electrical simulations.
    I urgently need an upgrade and would definitely go for a Ivy Bridge. But I've been waiting a long time now and Ivy Bridge may again been delayed.
    Does anyone have an advice about it?

    Thanks for sharing.

    How about OC? Info please?
    Is hard to decide wait until IB or get SB now because the how well IB can OC.
