Windows 7 Gaming Performance
Our Bench suite is getting a little long in the tooth, so I added a few more gaming tests under Windows 7 with a new group of processors. We'll be adding some of these tests to Bench in the future but the number of datapoints is obviously going to be small as we build up the results.
Batman: Arkham Asylum
Batman is an Unreal Engine 3 game and a fairly well received one at that. Performance is measured using the built in benchmark at the highest image quality settings without AA enabled.
Pretty much everything performs well here. Technically this is one of those exceptions where the i5 661 actually performs like it's priced. The i3s continue to be competitive with similarly priced AMD options.
Dragon Age Origins is another very well received game. The 3rd person RPG gives our CPUs a different sort of workload to enjoy:
Many games these days can actually use more than two cores, and thus we see the Lynnfield/Bloomfield chips scale ridiculously well here. As such, the i5 661 loses its appeal since it's priced like a Lynnfield.
The i3s however do very well. They outperform the similarly priced AMD CPUs and are just behind the Phenom II X4 925. They're definitely a lot faster than the old Core 2 Duo E8600 despite the clock speed deficiency.
Dawn of War II is a beautiful RTS that we've used in our GPU reviews for some time now. It scales will core count reasonably well but also shows the strengths of the new Clarkdales:
Again, the i5 661 isn't fast enough for its price but the i3s are great.
World of Warcraft needs no introduction. An absurd number of people play it, so we're here to benchmark it. Our test favors repeatability over real world frame rates, so our results here will be higher than in the real world with lots of server load. But what our results will tell you is what the best CPU is to get for playing WoW:
It's surprising how little difference there is between the i5 661 and the i3 540. It's almost as if Intel knew that the nomenclature had to exaggerate whatever little difference there was.
The i5 661 does well here, but the most bang for your buck comes from the i3s which even outperform the Phenom II X4 965. If you want an affordable gaming CPU, the Core i3 is where it's at.

The parent's office PC's aren't bottlenecked by the OS - they're not bottlenecked PERIOD. They run modern productivity apps just fine and would gain little to no benefit from Core i3 (or Windows 7 for that matter).Paulman - Monday, January 4, 2010 - link
Those office PC's you mentioned aren't bottlenecked by the 2GB of RAM. But I wouldn't say that they aren't bottlenecked, "period". What they ARE bottlenecked by is disk I/O, I'm sure. Throw in a good SSD and you would notice quite a bit of speed improvement, and probably a noticeable difference between the 1.6GHz and 2.4GHz machines.The most annoying thing to me whenever I'm using my PC is seeing and hearing my laptop HDD thrash around when launching an app or what not, because everything is held up as a result. Yes, I know it's a laptop HDD, but desktop drives are pretty slow, too.

SSDs are indeed fast, and make the whole computer feel "snappier"...However, these office machines never shut down (they hibernate overnight). IE8, Word, Excel, and Acrobat are always open and always stay open. Once loaded in memory, the hard drive is hardly used.
I've looked at upgrading them to 3GB of RAM, but they aren't using what they have, so why bother? Most of them use right around 1GB of RAM most of the time.
Could we put 40GB SSDs in? Sure, they are about $130 at Newegg right now... Not the end of the world, until you multiply that times 24 machines. Not a minor expense.

That is so true. This the first time in a long time that the computers have been "fast enough" for everything we use them for.There was a time in 1993/1994 that we were in this position, running DOS 6 and Windows 3.1 on 486DX2/66 machines, where the move to the DX4/100 or Pentium saw no benefit until Windows 95 came out. I worked in small shop back then, and we demoed a Pentium 66 machine, and saw zero benefit over the 486DX2/66 machines, other than it cost twice as much.
Perhaps in 2002, the Athlon XP machines were "fast enough" for Windows XP and Office XP, that was a nice time as well in the business. A Pentium III 550mhz was my last personal Intel chip until 2006, when I got my first Core2Duo machine at home. I had to work with some Pentium 4s at work during that time, Intel really, REALLY dropped the ball with the Pentium 4, IMHO.
Oh well... I've been doing this a long time, I still remember 5.25" floppy drives, with NO hard drive and those ugly green monitors with Hercules graphics... :)

But the 45nm package on Westmere doesn't just carry the GPU. They also moved the PCI-E controller and Memory controller there. I guess the "CPU" is still technically 32nm, but compared to Nehalem, half the "CPU" actually resides on a 45nm package on the chip...You can see a diagram in this Clarkdale review: http://www.hardcoreware.net/intel-clarkdale-core-i...">http://www.hardcoreware.net/intel-clarkdale-core-i...

Guess I should have read the whole review... You guys picked it up too! Not many others did though ;)ilnot1 - Monday, January 4, 2010 - link
I swear I've scoured the pages but I don't see your Test System Setup Chart: how much RAM, which graphics card? If it is there and I missed it I wish you could delete posts.Spoelie - Monday, January 4, 2010 - link
It's on page 6I'd like to know the setup of each memory benchmark on page 2. What memory speeds and settings were used for the latency and bandwidth numbers?
Anand Lal Shimpi - Monday, January 4, 2010 - link
All of the CPUs used DDR3-1333 running at 7-7-7-20 timings for that test. I used Everest 1909 (I believe, I'm about 2300 miles away from my testbed right now :-P) and CPU-Z's latency tool to grab the data.Take care,
Anand

I was looking for it too and its not there.
