The Sandy Bridge Factor
Intel’s Sandy Bridge architecture has received a lot of attention since its introduction in early January, first for its impressive performance, and more recently for the P67/H67 chipset’s 3 Gb/s SATA performance degradation problem. Despite this hiccup, Intel representatives tell us that the B3 stepping of Cougar Point is already being shipped to vendors and should emerge sooner than originally expected. The new architecture is here to stay and could potentially impact every desktop CPU price point it touches.
Intel is being a lot more aggressive with those price points, too. The lowest-priced Lynnfield-based CPU with a true quad-core architecture (that’s the Core i5-750) starts at about $200. But the Sandy Bridge-based Core i5-2300 can be purchased for $185. This means that Intel’s newest quad-core processors are no more expensive than AMD’s premium Phenom II X4 970.
And what about the $100-to-$150 market? When the dual-core Hyper-Threaded Core i3-2100 and -2120 finally make their way to market, we expect them to be available in that strategically-priced range. Preliminary testing from our launch coverage, Intel’s Second-Gen Core CPUs: The Sandy Bridge Review, showed us that the new Core i3 CPUs have tremendous gaming potential, and might even be able to challenge AMD’s quad-core flagship in this arena.
Indeed, game performance is what this article is all about. Up until now, AMD's Phenom II X4 and Athlon II X3/X4 processors have vigorously defended their status as value-packed engines in inexpensive gaming systems using sub-$200 price tags. Between June of last year (Game-Off: Seven Sub-$150 Processors Compared) and now, we've seen AMD add a couple hundred megahertz to each price point. Yes, we like more performance without a corresponding rate-hike. But the company is competing with architectural updates that make a far more profound impact on performance. Will incremental speed bumps be enough to help the company defend its position in the sub-$200 market, or will the least-expensive Sandy Bridge-based processors steal the spotlight?
We’re comparing the relevant sub-$200 CPUs; 12 models in total. Before we talk about the contenders, let’s address the processors not being included. We’re leaving out the Core i5-750, as we’ve already proven that the Sandy Bridge-based Core i5s are faster gaming processors. We’re not including dual-core processors without Hyper-Threading because we’ve shown that modern games require a minimum of three threads to demonstrate the best possible performance. LGA 775 did not make our list either, because it’s now three generations old.
Even after trying to narrow down the field, we have a lot of CPUs to test. The Clarkdale-based Core i3-550 and Core i3-560 are known decent products, and the Core i3-2100 and Core i3-2120 will show us what Intel’s newest dual-core Hyper-Threaded offerings can accomplish. The Sandy Bridge-based Core i5-2300 and Core i5-2400 represent true quad-core performance. Three quad-core models and the hexa-core Phenom II X6 1075T represent AMD's highest-end processors. On the lower end of the spectrum, we have the fastest quad- and triple-core AMD processors available for under $150: the Athlon II X4 645 and the Athlon II X3 455.

o_O I'd like me one of those
a pc will never be gaming only, unless you have more than one, in that case, for for the cheaper dual core hyperthreaded, but if you do anything else, get a real quadcore and don't even take into consideration the logical cores.
AMD build w/AMD Athlon II x3 455 w/Asus 870 based mobo:
$89 for Athlon II x3 455
$90 for AMD mobo (Asus) w/6xSATA 3, 6 USB 2.0, 2 USB 3.0, 4 x DDR3 slots.
ASUS M4A87TD/USB3 AM3 AMD 870 SATA 6Gb/s USB 3.0 AMD Motherboard
Intel build w/i3 550 w/P55 based mobo (Asus also):
$130 i3 550
$150-$10 MIRc Comparable mobo (Asus also) 6xSATA 3, 6 USB 2.0, 2 USB 3.0, 4 DDR3 slots.
ASUS P7P55D-E LX LGA 1156 Intel P55 SATA 6Gb/s USB 3.0 ATX Intel Motherboard
**These are all Newegg prices**
AMD build (using the same Case/PSU/RAM/DVD parts in both systems)
$179 + shared parts.
Intel build (same parts shared w/AMD build)
$280 + shared parts.
This equals out to ~$100 price difference between the 2 builds, which to me is quite a bit!
So in general when trying to factor in "Value" for the gaming buck I still see the AMD based system being the better buy. Assuming your using mobo's with about the same features. If you notice the Intel based mobo's will cost you more for similar AMD based mobo's. This is where a lot of the value comes from AMD. Don't get me wrong here, the Intel based system is very good system too, you just have to pay more for them.
Yes the amd build is pretty cheap, but swap you're i3 550 with the i3 2100 and the p55 mobo with the p67 mobo, and you have a build that is now worth the $100 over the amd build
also I think this conclusion summarizes well AMD's predicament in a months time:
"the Core i3-2100 performs as well as (or slightly better than) AMD's Phenom II X4 970 flagship."
I almost missed this typo an AMD pentium hmmm something seems wrong.
If the point is that Intel has the best budget system at the current prices - then yes, the point is made. But it looks more like you're trying to prove Intel is better just before AMD launches a new generation of CPU's. While I can't speak for anyone else, I'm at least going to give their next generation a chance.
Certainly no one needs quad cores for web browsing and word lol.
