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.

It would have been interesting to see. Personally, I don't care for IGP, as they sit disabled anyway. Right now, it seems like it's a 7% clock for clock perf increase, which is very poor for one process node. Knowing where the clocks can be will let everyone know exactly how much faster the CPU can be over SB.NeBlackCat - Wednesday, March 7, 2012 - link
For me, the most interesting things about IVB are improved multi-monitor support, and power savings not just at stock, but also undervolted (stock clock) and overclocked.Because I want to know if I'm finally going to get that laptop or mini-itx system that can drive several monitors while remaining cool and sipping power, even under load.
Not covered at all. Shame.

Intel marches on. Their domination of 80+% of all CPU markets will continue.silverblue - Wednesday, March 7, 2012 - link
PC and especially server market, sure, but not smartphone/tablet. Not yet, anyway.fvbounty - Wednesday, March 7, 2012 - link
Should have a had SB 2700K to run clock for clock against the 3770K and see if there's much difference!ellarpc - Wednesday, March 7, 2012 - link
Agreed! I was just about to post that same comment. It doesn't make much sense to compare it to a lower clocked SB product. Well unless you wanted to make the IB look better. Now I'm going to sift through anand's past reviews to see what kind of gains the 2700 has over the 2600.ellarpc - Wednesday, March 7, 2012 - link
Doesn't look like Anand has a 2700k for testingueharaf - Wednesday, March 7, 2012 - link
I was thinking that the difference in gpu perfomance between HD3000 and HD4000 about 20% to 40% increase perfomance, will remain in the ivy-bridge mobile chips!!! I hope soo!!!lilmoe - Wednesday, March 7, 2012 - link
Great review. You guys know your stuff. I've been waiting for a review like this since IvyBridge was announced.However, I'll still "cling to my Core 2" since it does the job now, and I'll postpone my upgrade till next year. You make it seem like Haswell is a good reason to wait. I bought the system in early 2010, and I usually upgrade every 2-4 years. 3 years sounds just right. I'll be investing in SSDs since you talked me into it though, it seems a better upgrade at the moment.

Did Intel specifically ask not to include overclocking tests in ES previews?
