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.

CPU perf pretty much as expected,GPU perf somewhat dissapointing ,i thought they'll at least aim to match Llano but i guess it is ok for 1MP laptops screens if mobile parts perform close enough (and a couple of big ifs when it comes to image quality and drivers).Any opinions yet about QuickSync encoding quality?

And we should remark that's comparing 2600 with 3700 which have different cpu too.Other benchmarks had significantly better results on 3700 than 2600.
So Anand, how you know that difference is not attributable to the CPU and not to some gpu improvement? Reply

You are not being serious, are you? The CPU gets 10% in CPU sensitive benchmarks and GPU gained 40-60%. Even taking out 10%, its still 30-50%, which btw isn't true as games aren't very sensitive to CPU changes as applications do. Replywifiwolf - Wednesday, March 07, 2012 - link
Look at crisys or metro benchmarks and tell me where you find that improvement, at least more than what you find in cpu difference. Replymosu - Wednesday, March 07, 2012 - link
I've tried it on some HD clips at a local TV station and on a big screen it really sucked.It's way behind AMD.We used aHP EliteBook 8460P laptop. ReplyArticuno - Tuesday, March 06, 2012 - link
At least AMD's products are HD capable. Replydr/owned - Thursday, March 08, 2012 - link
My 5 year old laptop with a shared ram gpu is "HD capable". GTFO noob. ReplyArticuno - Tuesday, March 06, 2012 - link
Billions in R&D, double the MSRP, half the power and yet it still can't play Crysis better than Llano, which will be replaced by Trinity in a few weeks. What a crying shame. Replytravbrad - Tuesday, March 20, 2012 - link
Not playing Crysis sounds like a good thing to me. Replytipoo - Tuesday, March 06, 2012 - link
Source or gtfo. Apple got the stock HD 3000, why would this be different? Reply
