The Sandy Bridge Review: Intel Core i7-2600K, i5-2500K and Core i3-2100 Tested
by Anand Lal Shimpi on January 3, 2011 12:01 AM ESTGaming Performance
There's simply no better gaming CPU on the market today than Sandy Bridge. The Core i5 2500K and 2600K top the charts regardless of game. If you're building a new gaming box, you'll want a SNB in it.
Our Fallout 3 test is a quick FRAPS runthrough near the beginning of the game. We're running with a GeForce GTX 280 at 1680 x 1050 and medium quality defaults. There's no AA/AF enabled.
In testing Left 4 Dead we use a custom recorded timedemo. We run on a GeForce GTX 280 at 1680 x 1050 with all quality options set to high. No AA/AF enabled.
Far Cry 2 ships with several built in benchmarks. For this test we use the Playback (Action) demo at 1680 x 1050 in DX9 mode on a GTX 280. The game is set to medium defaults with performance options set to high.
Crysis Warhead also ships with a number of built in benchmarks. Running on a GTX 280 at 1680 x 1050 we run the ambush timedemo with mainstream quality settings. Physics is set to enthusiast however to further stress the CPU.
Our Dragon Age: Origins benchmark begins with a shift to the Radeon HD 5870. From this point on these games are run under our Bench refresh testbed under Windows 7 x64. Our benchmark here is the same thing we ran in our integrated graphics tests - a quick FRAPS walkthrough inside a castle. The game is run at 1680 x 1050 at high quality and texture options.
We're running Dawn of War II's internal benchmark at high quality defaults. Our GPU of choice is a Radeon HD 5870 running at 1680 x 1050.
Our World of Warcraft benchmark is a manual FRAPS runthrough of a lightly populated server with no other player controlled characters around. The frame rates here are higher than you'd see in a real world scenario, but the relative comparison between CPUs is accurate.
We run on a Radeon HD 5870 at 1680 x 1050. We're using WoW's high quality defaults but with weather intensity turned down all the way.
For Starcraft II we're using our heavy CPU test. This is a playback of a 3v3 match where all players gather in the middle of the map for one large, unit-heavy battle. While GPU plays a role here, we're mostly CPU bound. The Radeon HD 5870 is running at 1024 x 768 at medium quality settings to make this an even more pure CPU benchmark.
This is Civ V's built in Late GameView benchmark, the newest addition to our gaming test suite. The benchmark outputs three scores: a full render score, a no-shadow render score and a no-render score. We present the first and the last, acting as a GPU and CPU benchmark respectively.
We're running at 1680 x 1050 with all quality settings set to high. For this test we're using a brand new testbed with 8GB of memory and a GeForce GTX 580.

Time for an upgrade :)marc1000 - Monday, January 3, 2011 - link
I decided to jump the first core-i lineup, and sitck to an old core2duo for some more time... now seems the wait was worth it!I just hope the prices outside US/Europe will be reasonable..
thanks Anand,

I think there are many of us that had the same idea. Unless needing to upgrade due to malfunction or new laptop purchase, holding C2D til past the i-Series was the best move to make; whereas buying into C2D asap was the best move at the time.Still going to wait for prices to fall and more USB3 adoption. Expected new purchase: mid-2011-mid 2012

by "i-Series" it should have said "1st gen. i-Series"CptTripps - Tuesday, January 4, 2011 - link
Ya know I usually do as you are but was an early adopter of the i7 920. Looking now it seems I made the right choice. I have had 2 years of kickassery and my processor still holds up rather well in this article.hogey74 - Thursday, January 6, 2011 - link
Me too! I've got an e8400 running at 3.9 with almost zero OC know-how and its done me well. I might snap up an i7 if they and their mobos get cheap when sandy bridge has been out a few months... but may well skip that generation all together.Einy0 - Monday, January 3, 2011 - link
Holy crapola AMD really needs Bulldozer now. Even in heavily threaded video encoding the 2600K at $300 is blowing the 1100T x6 out of the water. This is the the Core 2 Duo vs. A64 X2 all over again. Will Bulldozer be another Phenom, a day late and a dollar short? TLB bug anyone? As a PC enthusiast I really want to see competition to keep prices in check. If I had to upgrade today, I can't see how I could turn down the 2600K...medi01 - Monday, January 3, 2011 - link
Did you add mobo price into equation?I don't get all the excitement, really. If anything, Intel's anti-overclocking moves

Yeah, new Intel motherboard models are never cheap. I don't understand why the price remains so high when more an more functionality is moving to the CPU. The other killer is that you need a new board for every Intel CPU update.Lastly, it's hard to throw the "buy now" tag on it with AMD's new architecture over the horizon. Sure, AMD has a tough act to follow, but it's still an unknown that I think is worth waiting for (if it's a dog, you can still buy Intel). Keep in mind that Bulldozer will have a pretty strong IGP, one that may make decent IGP gaming a reality. It will become a matter of how powerful the x86 portion of the Bulldozer is, and they are trying a considerably different approach. Considering the amount of money you'll be paying, you might as well see how AMD shakes out. I guess it just depends on if what you have today can get you by just a little longer.

You're conflating Bulldozer and Llano there. Bulldozer is the new architecture, coming to the desktop as an 8-core throughput monster. Llano is the first desktop APU, cramming 4 32nm K10.5 cores and a Redwood class GPU onto the die. The next generation of desktop APUs will be using Bulldozer cores.
