Compression & Encryption Performance
7-Zip Benchmark
By working with a small dataset, the 7-zip benchmark gives us an indication of multithreaded integer performance without being IO limited:
Although real world compression/decompression tests can be heavily influenced by disk IO, the CPU does play a significant role. Here we're showing a 15% increase in performance over the 2600K. In the real world you'd see something much smaller as workloads aren't always so well threaded. The results here do have implications for other heavily compute bound integer workloads however.
TrueCrypt Benchmark
TrueCrypt is a very popular encryption package that offers full AES-NI support. The application also features a built-in encryption benchmark that we can use to measure CPU performance:
Our TrueCrypt test scales fairly well with clock speed, I suspect what we're seeing here might be due in part to Ivy's ability to maintain higher multi-core turbo frequencies despite having similar max turbo frequencies to Sandy Bridge.

"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."Basically all the laptops in the last few years for business have been bought with C2D. I think with Ivy, it's a great time to upgrade them all and see a good improvement. Same for family members too. I can't wait to try them out! Thanks for the review Anand.

maybe intel should drop the graphics all together, i don't like it, let the pro take care of it. just too much.dr/owned - Thursday, March 8, 2012 - link
This article blows because there's no overclocking results. We're not looking for a fine tuned overclock. Just give us the rough and dirty! My money is on 5 ghz with minimal effort using an air cooler.dagamer34 - Thursday, March 8, 2012 - link

It seems like Intel has the tick-tocks backwards. The i7-920 is arguably the greatest cpu to come out in recent years and it was "just" a tick.Wardrop - Thursday, March 8, 2012 - link
I'm afraid you have it backwards.The i7-920 is a Nehalem processor (it's a 45nm chip). It's a tock. Why is this concept so hard to grasp?

Look at the chart. Nehalem (i920) was a tock.just4U - Thursday, March 8, 2012 - link
I have to disagree with you on the i920 being such a huge leap. As someone who goes thru virtually every cpu line up for AMD/Intel I'd have to say the C2D (or quad) 6x series was the biggest leap forward in the past decade. Before that it was the A64 and X2 variants (altho.. we didn't get alot of use out of those secondary cores)IntelUser2000 - Thursday, March 8, 2012 - link
LOL, this must be the most hilarious argument I've heard in a while.How do you relate 30+ % graphics gain as being ALL CPU? Don't be ridiculous, and that's an understatement.

Are low-res testing really relevant for graphics?Most players play at 1920x1080 or higher.
1368x720 or 1680x1050 does not seem relevant to me at all for most people, especially those purchasing a computer with this processor.
