Benchmark Results: Synthetics

by

Sandra shows signficantly improved computing power for the Core i5-661 at 3.33 GHz, but this doesn’t necessarily reflect real-world applications. However, have a look at the encryption benchmark results, which are much accelerated on the new Clarkdale CPU.

This is one of the most amazing results. Thanks to Intel’s six additional instructions accelerating AES encryption and decryption, the performance boost is almost 12x when compared to the Core 2 Duo E8600. Keep in mind that we did not have to modify or update the benchmark to get these results.

The encryption score is similarly high, although SHA is not supported.

The increased memory bandwidth is most likely a result of the on-package memory controller (which, in turn, isn't as effective as Lynnfield's on-die memory controller).

PCMark Vantage also shows decent performance gains for the Core i5 versus the Core 2 Duo processor at the same nominal clock speed. Keep in mind that Core i5 takes advantage of its Turbo Boost feature, which lifts the CPU to a maximum of 3.60 GHz.

I'm still trying to figure out why you're comparing a new $196 intel chip against sup $100 AMD offerings?

@ reidd105
The only answer I have now is to make Intel win on all fronts.

I spent time yesterday writing a comment, pointing out how in Anandtech's review of the Athlon 435, they found the 240e actually uses 10 watts more power versus the 605e. The 605e can be had for around $170 and might beat the i5-661 in some video and 3d rendering tasks.

I logged on this morning to check to see if anyone else had posted, to find that the link from the home page brings be here and the comments are missing. Below is a slightly different link to the older article.

Can someone from Toms please answer why this is going on?

intels turbo boost + built in gpu + hyperthreading vs not oced black edition cpu + northbridge = unfair battle?

i5-661 - 200$
core 2 duo E8600 - 280$
H55 mobo ~ 100$

phenomII X2 550 - 100$
athlon x2 240e -

QUOTE: "The Core i5-661 is a unique model from Intel with the family's fastest graphics clock. Its HD Graphics unit runs at 900 MHz, as opposed to the 733 MHz found on all other Core i3/i5 processors. Other than that, there are no differences between the models."

Actualy there are, see: http://download.intel.com/design/p [...] 322911.pdf page 16.
Beside the difference in graphics speed the 661 has none of the advanced hardware virtualisation technologies that the other i5's do have.
For some that might not make any difference but it might be something to keep in mind when choosing between the i5's

I don't understand how the performance of the Clarkdale is so much faster than the Wolfdales in this article but is about the same speed in clock for clock in other test articles such as the ones on anandtech and xbitlabs. Particularly look at the gaming fps. It is not consistent at all.
