Benchmark Results: PCMark Vantage Communications Test
PCMark Vantage says the same. The overall communications score is 50% better on the new 32nm Clarkdale dual-core than on the 45nm Lynnfield quad-core chip.
And here is why.
Again, Intel only accelerates AES. Data compression doesn’t benefit. Rather, it depends on core count and clock speed.
Decryption that includes AES is also significantly faster.
Here is one more synthetic metric where Intel's Clarkdale-based Core i5-661 shines thanks to AES support.

Good grief. About 3 mistakes on the first page!
I may be being a bit skeptical, butputting on the highest i5 chips that include a GPU? Does this not sound like a money spinner?
Nice to see that Intel have finally caught up with Via...
Shame we can't see any benchmarks to compare the performance of the AES engines.
I'd think it's not all good things coming from this ability.
Malware programmers can benefit from it as it should accelerate decrypting passwords and alike.
Gee lets compare a quad core to a dual core? WTF! No balance or objectivity here at all! This got past the editors how?
How does the CPU knows about to use the ASE instructions? Is there a special library comming with the Benchmarks?
Please do some Linux tests! IMHO the support for the new AES-NI has been in the kernel for quite some time (done by Intel long before those CPUs even came to the market!) and dm-crypt is a very nice way to test REAL WORLD speeds.
Imagine new i5 without AES-NI! Why would you buy it anyway when it is always inferior compared to i7? Well - there comes Intel marketing guys and say: We will put AES-NI just in i5 (in the beginning) hoping that the product will attract some buyers. If they put now AES-NI in i7, i5 will be doomed processor.
This would be very nice in a firewall. VPN thoughput on one of these CPU's would be awsome.
My Guess is that where this CPU will end up. The next gen of Cisco ASA series and the like.
Still kinda sucks... as the AES-NI is only for the 1156 socket. Unless I feel like forking out 1K for the 980x (1366)
