AnandTech Ivy Bridge Performance Preview

[Ryan Smith]

Hi guys;

We've been working on a little something over the weekend that you might be interested in. I assume you all know what Ivy Bridge is?

[jpeyton]

Great article! I'm surprised that Llano kept a decent GPU advantage over Ivy Bridge; I was expecting them to be equal.

 

[Vesku]

Yes, surprised at the SC2 numbers.

 

[Rvenger]

Actually surprised of the systemmark numbers. This CPU seems like its taking a nice little lead over the 2600k.

 

[Hidden Hippo]

Where does this CPU fit within the new price point? If I were to extrapolate those results to the 2500k equivalent, what sort of increase would you likely see (tangible increase as opposed to number increase)?

 

[jimpatrick]

seems just right for the new 2600k aka 3770k.

 

[Arachnotronic]

Why is Intel focusing on the freaking IGP? More CPU performance/cores, please!

 

[Hulk]

Thanks for the great preview. I hate to be greedy but I was hoping for just a little bit of overclocking info!

Thanks for the great preview. I hate to be greedy but I was hoping for just a little bit of overclocking info!

The search for overclocking info was the only reason I even opened the article .

 

[jimpatrick]

yeah yeah overclocking,want to see how good a 22nm is.

 

[thilanliyan]

Hmm...IB might tempt me for something more power efficient.

 

[IlllI]

I am more interested in i5 benchmarks.

 

[TidusZ]

Why no overclocking testing?

 

[Ferzerp]

It says it's just a preview. I would imagine more to come soon(ish).

 

[Maximilian]

Theres actually quite a lot in there for "just a preview". Highly anticipate the full review with overclocking benches :thumbsup:

 

[IntelUser2000]

Yes, surprised at the SC2 numbers.

The reason for that is likely because TDP is shared between the CPU and GPU. While the absolute performance might be good, relative to discrete parts there's a greater loss since CPU sensitive games rob GPU of its power budget.

It looks to me that performance of HD Graphics 4000 is geometry limited. GPUs with low geometry performance perform better in higher resolutions/settings since the bottleneck is elsewhere, but in lower resolutions and settings, geometry performance starts to become important.

Low hardware geometry performance is why the original GMA X3000 performed almost bad in lower settings/resolutions as it did in higher ones. In most GPUs, you could lower settings to get better performance, but not in this case. In higher settings, there's not enough shader/pixel power anyway, in lower resolutions geometry performance held it back.

 

[TidusZ]

I would take it since they released all this information that there is no NDA, so hopefully they get o/c results out soon

 

[LagunaX]

Lookin' fer 24/7 5ghz...

 

[Quantos]

Nice, that's pretty much what was expected and Intel delivers. That's a very different feeling than what we have in, say, the GPU market. We're basically told months before hand what to expect, and it arrives mostly on time and the predicted performance.

Me wants!

 

[Absolute0]

A few % better than I expected, very nice, Intel keeps putting out sweet CPUs

now NEED OC RESULTS

 

[DarkRogue]

Delicious.

Looking forward to jumping over to a 3770k from my e8400. Lightroom is starting to struggle.

Can't wait for OC results as well.

I was thinking about upgrading to an i7 3930k from my i7 2600k because I wanted 6 cores and quad channel memory configuration but I think I might upgraded to an i7 3770k and a Z77 chipset motherboard instead since looking at the gaming benchmarks. If that is not a typing error about the i7 3770 being 3.4GHz then I would choose the i7 3770k over the 3770 even if I won't overclock.

I was having thoughts about replacing my motherboard since my motherboard doesn't have a C1E setting in the BIOS and I'm skipping the Z68 Gen 3 boards and it would just be less hassle for me to buy a Z77 motherboard with a new CPU than to buy a Z68 Gen 3 motherboard now, replace my current one, use same CPU, Ivy bridge comes out, and take out motherboard again to replace CPU. I'm using a Hyper 212+ so I have to take out my motherboard if replacing the CPU anyways.

 

[LOL_Wut_Axel]

Well, what I said about three months ago and what was obvious: 10% faster, where 5% comes from higher IPC and the other 5% from slightly higher clock speed.

Nothing groundbreaking, but support for PCIe 3.0 is very nice.

 

[Hulk]

Tocks are never as exciting as ticks I think most would agree. A die shrink, some new features, better thermals and overclocking. Pretty cool but not that much of a thrill. But a tick brings pages and pages of new architectural improvements with lots of cool diagrams and hours of reading to try and figure it all out (for me anyway) before you see the actual IPC improvements in various applications in the benchmarks. We're always looking for the next release to be as dramatic a performance improvement as we witnessed in going from P4 to Conroe. That was nearly a doubling of performance per clock. It spoiled us.

All that said I'm grabbing one of these as soon as I can.

 

[grkM3]

Wow lol your so smart and im sure the rest of the millions of people that already figured that but didnt bother posting it must be upset you get all the credit.

Im typing this on an es ivy btw
