Final Words

In terms of absolute CPU performance, Sandy Bridge doesn't actually move things forward. This isn't another ultra-high-end CPU launch, but rather a refresh for the performance mainstream and below. As one AnandTech editor put it, you get yesterday's performance at a much lower price point. Lynnfield took away a lot of the reason to buy an X58 system as it delivered most of the performance with much more affordable motherboards; Sandy Bridge all but puts the final nail in X58's coffin. Unless you're running a lot of heavily threaded applications, I would recommend a Core i7-2600K over even a Core i7-980X. While six cores are nice, you're better off pocketing the difference in cost and enjoying nearly the same performance across the board (if not better in many cases).

In all but the heaviest threaded applications, Sandy Bridge is the fastest chip on the block—and you get the performance at a fairly reasonable price. The Core i7-2600K is tempting at $317 but the Core i5-2500K is absolutely a steal at $216. You're getting nearly $999 worth of performance at roughly a quarter of the cost. Compared to a Core i5-750/760, you'll get an additional 10-50% performance across the board in existing applications, and all that from a ~25% increase in clock speed. A big portion of what Sandy Bridge delivers is due to architectural enhancements, the type of thing we've come to expect from an Intel tock. Starting with Conroe, repeating with Nehalem, and going strong once more with Sandy Bridge, Intel makes this all seem so very easy.

Despite all of the nastiness Intel introduced by locking/limiting most of the Sandy Bridge CPUs, if you typically spend around $200 on a new CPU then Sandy Bridge is likely a better overclocker than anything you've ever owned before it. The biggest loser in the overclock locks is the Core i3 which now ships completely locked. Thankfully AMD has taken care of the low-end segments very well over the past couple of years. All Intel is doing by enforcing clock locks for these lower end chips is sending potential customers AMD's way.

The Core i3-2100 is still a step forward, but not nearly as much of one as the 2500K. For the most part you're getting a 5-20% increase in performance (although we did notice some 30-40% gains), but you're giving up overclocking as an option. For multithreaded workloads you're better off with an Athlon II X4 645; however, for lightly threaded work or a general purpose PC the Core i3-2100 is likely faster.

If this were a normal CPU, I'd probably end here, but Sandy Bridge is no normal chip. The on-die GPU and Quick Sync are both noteworthy additions. Back in 2006 I wondered if Intel would be able to stick to its aggressive tick-tock cadence. Today there's no question of whether or not Intel can do it. The question now is whether Intel will be able to sustain a similarly aggressive ramp in GPU performance and feature set. Clarkdale/Arrandale were both nice, but they didn't do much to compete with low-end discrete GPUs. Intel's HD Graphics 3000 makes today's $40-$50 discrete GPUs redundant. The problem there is we've never been happy with $40-$50 discrete GPUs for anything but HTPC use. What I really want to see from Ivy Bridge and beyond is the ability to compete with $70 GPUs. Give us that level of performance and then I'll be happy.

The HD Graphics 2000 is not as impressive. It's generally faster than what we had with Clarkdale, but it's not exactly moving the industry forward. Intel should just do away with the 6 EU version, or at least give more desktop SKUs the 3000 GPU. The lack of DX11 is acceptable for SNB consumers but it's—again—not moving the industry forward. I believe Intel does want to take graphics seriously, but I need to see more going forward.

Game developers need to put forth some effort as well. Intel has clearly tried to fix some of its bad reputation this go around, so simply banning SNB graphics from games isn't helping anyone. Hopefully both sides will put in the requisite testing time to actually improve the situation.

Quick Sync is just awesome. It's simply the best way to get videos onto your smartphone or tablet. Not only do you get most if not all of the quality of a software based transcode, you get performance that's better than what high-end discrete GPUs are able to offer. If you do a lot of video transcoding onto portable devices, Sandy Bridge will be worth the upgrade for Quick Sync alone.

For everyone else, Sandy Bridge is easily a no brainer. Unless you already have a high-end Core i7, this is what you'll want to upgrade to.

    You'd spend $80 on a 6-core MB ?? LOL

    If you buy a 6-core Phenom, likely you'll be in th 140-180 range for a decent MB..

    Funny how the cheapers rationalize their cheapness.

    That's not true at all. Most $40-50 AM3 mobo's support X6. If you don't game or overclock, you don't need extra pci-e lanes and extra cooling. Especially for a workstation. Reply

    Yeah, I'm stoked about the new low-level DRM.

    This is sure to run it fast.

    i think that amd 880g mainbord with cpu araound 90 dolars plus some 55xx series gpu can do better in terms of encoding decoding video playback games etc. and all that without alot of money spend on inetl new socekets wich you have to trow away when they make the next cpu.So please corect me if i am wrong

    The charts and the numbers say it all. This is definitely worth an upgrade for me!

    Hi everyone, i dicided to build a PC but made an 1 error getting the i7 2600 if anyone is interested in buying one please let me, it's brand new sealed in it original contents.

    and i dont mind trading it in for a i7 2600k.

    and i will match the price maybe even better

    I'm wondering how supply will be on release day? Often we see new components with low supply and online stores start price gouging from day one. New Egg is particularly known for such. Lets hope supply is very good off the bat. That 2600K looks really appealing to me. Reply

    One of the local computer stores had Sandy Bridge parts up for sale last week, but they're all gone now save for a few Asus P8P67 standard, pro, and deluxe boards.

    I wasn't able to see what kind of money they were asking.

    This review has convinced me that once the 2600K shows up again it's all I'll need. I was going to wait for socket 2011 but damn, the 2600 is already more than twice as fast in everything than my poor ol' Q6600.

    I'm also curious if there will be a hybrid P/H type mobo that will allow for OC'ing all components. Reply

    Yes. There will be a Z series to be released in the 2Q11. Reply
