Benchmark Results: PCMark Vantage

Intel’s Second-Gen Core CPUs: The Sandy Bridge Review
By

Three Sandy Bridge-based CPUs top the Overall chart, followed by the Core i7-875K, which benefits from its ability to Turbo Boost up to 3.6 GHz.

Although Intel’s Core i7-950 runs at a faster base clock rate and enjoys the throughput of a triple-channel DDR3 memory interface, its highest official memory data rate is 1066 MT/s (compared to Lynnfield’s 1333 MT/s). And it probably doesn’t help that the 900-series processor can only Boost to 3.33 GHz.

A lack of software able to fully utilize six cores and a lower base clock rate hurts AMD’s Phenom II X6 1100T overall. You do see that, in certain disciplines, like TV and Movies and Communications, the hexa-core chip’s standing improves. Meanwhile, the Phenom II X4 970 sees a comparative advantage thanks to its fixed 3.5 GHz clock rate.

This won’t be the first time I say this in my benchmark analysis: if Phenom II were living in a Core 2 world, it’d be sitting pretty. Up against Nehalem, it simply gets outclassed. Compared to Sandy Bridge, it’s just not close. But then again, PCMark Vantage is technically a synthetic. Let’s keep moving and see if more specific workloads change the story our data tells.

    "an unlocked Sandy Bridge chip for $11 extra is actually pretty damn sexy."

    Editor, page 10 has mistakes. Its LGA1155, not LGA1555.

    Great article guys. Glad to see you got your hands on those beauties. I look forward to you doing the same type of review with bulldozer. =D

    Wow Intel owns when it came to converting video, beating out much faster dedicated solutions, which was strange but still awesome.

    I don't know how AMD's going to fare but i hope their new architecture will at least compete with these CPU's, because for a few years now AMD has been at least a generation worth of speed behind Intel.

    Also Intel's IGP's are finally gaining some ground in the games department.

    I really wish this weren't the case fakie--and I'm very sorry it is. We're unfortunately subject to the will of the finance folks and the government, who make it hard to give things away without significant tax ramifications. I know that's of little consolation, but that's the reason :( 

    Best,

    "It’s the value-oriented buyers with processor budgets between $100 and $150 (where AMD offers some of its best deals) who get screwed."

    I believe that says it all. Sorry, Intel, your new architecture may be excellent, but unless the i3-2100 series outperforms anything AMD can offer at the same price range WHILE OVERCLOCKED, you will see none of my desktop dollars.

    That is all.

    ... will wait til 'buldozer'... and two things may happen... the buldozer at the price point will kick ass... or the sandy bridge parts will get cheaper...

    There is some pretty cool stuff going on here. I like the way the article points out the good and the bad. As for me I really am mystified at Intel's decision to only put the higher end graphics in the k-models as most likely anyone buying them will be going for the P67 platform that doesn't even use the integrated graphics. It would have been soooo much better for the HTPC crowd if there were some lower end chips with the better integrated graphics. I guess somehow this is money motivated???

    As for overclocking, well it seems a bit odd in the way it is being implemented. But for $216, I can't complain too much about a quad-core with a base clock of 3.3 GHz. Some enthusiasts won't like the limited overclocking features, but others will welcome the simplified approach.

    I will be building my brother a new gaming computer for graduation this summer and now I have another viable option to look at. I had planned on going with a P55 + i5 760, but now I will need to consider the P67 + i5 2500K.

    Waiting on bulldozer...

    I mean this looks like a thorough test but its really not. I wanted to see an I7 1:1 clock performance comparisons. Mainly, 3.4GHz I7-950 vs 3.4GHz I7-2600K. Obviously 3.4 GHz new tech would usually beat a 3.0 current tech in benches. UGH. lame lame lame. Really want to see this comparison instead.

    Shouldn't the title be second gen Core i series... because Core 2s were second gen Cores, weren't they?

    Where is the 980x in these benchmarks?
    Other than that its a great article, and I'm drooling over QuickSync!

    Thanks for the review Chris :) 
    QuickSync definitely looks interesting.

    I just bought an i5-760 system on 12/30 from newegg, I guess I wasn't paying attention to when Sandy Bridge would actually be released. It's not here yet, so I could just send the mobo and cpu back when they get here, but I don't see enough justification as a gamer to move to the 2500k. Based on the number of 1.35V 4.7ghz for the 2600k, I would assume that on stock voltage it doesn't get much higher in frequency than my 760 will, and I don't like raising stock voltage.

    This is all very nice, but I'll keep my bclk control for now and maybe move up when I get out of college in seven months and the tech is set in stone and dropping in price a little.

    Not a bad chip, and I'm excited to see where they go with it. =]

    Is sandy bridge the replacement to the x58 chipset? I thought I read somewhere they were planning on x68 sometime in 2011.

    Remember though as this is the lower end Sandy Bridge platform NOT THE MAIN LGA2011 socket. As Intel decided to release for the mainstream first before the enthusiasts this go around.

    Just looked at the AnandTech review and here is their opinion -

    Quote:
    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.


    These things are as fast as the i7 980X and in some cases they're even faster!
