Intel Core i5-661: Clarkdale Rings The Death Knell Of Core 2

Benchmark Results: Left 4 Dead 2

Left 4 Dead is much more contingent on processor performance, but that dependency is only really prominent at low resolutions and without anti-aliasing or anisotropic filtering. At 1680x1050, we see the Lynnfield-based Core i5-750 delivering the highest frame rates, followed by AMD’s Phenom II X4 965. Those two are on even footing once you add AA and AF into the mix, though.

At 1920x1200 and then 2560x1600, it’s much harder to tell between the CPUs on our test bench. Only one thing remains consistent: the Core 2 Duo E8500 pulls up last place, making our past recommendations that you invest in a triple- or quad-core CPU all the more relevant.

    Well... I think that takes care of the dreaded "But can it play Crysis?" question regarding its GMA :D :P :P

    can i ask why you teased us at the end with the 4.5ghz OC but didn't include them in the benchmarks? =

    Fixed! Had to keep it private pre-launch :)

  • I really like the improvements Larrabee brought about....not! I do like the fact they are making progress but they really need to skip ahead a few generations or buy out some other company to design a GPU for themselves.

    ^ Many more reasons to buy AMD Phenoms II X4 in the mid-range segment...
    Only drawback with the AMD CPUs is the power consumption, that I feel can be brought down with slight undervolting...

    I'm looking to upgrade from my Athlon X2 @ 2.7GHz because I do more with the computer now than I did before - sometimes I'll play a game while my TV tuner is recording from my cable signal, and having more cores would help these multiple tasks run more smoothly.
    I was waiting until the Clarkdale-based i5 launched, thinking it would be a quad-core that was more competitively priced against the Phenom II X4, but it looks like a Phenom II X4 is my only option to get more cores for less money.
    The only good news coming out of this launch is that LGA1156 is not changing for the Clarkdale chips, so it looks to be the most future-proof platform to upgrade to, if one was so inclined. I'm personally going with a Phenom II since I can get one without changing motherboards. This is one of the more disappointing launches in the last year or so.

    We have another overclocking piece planned--I wanted to get a Core i3, at least, to include :)

  • I would love to see what GTA IV would do do the dual cores in gaming! I do know that its a bear of a game on the CPU and it would truly show off if hyperthreading could actually make a major difference.

    Great video once again! Thanks for this and the review itself. Very informative. I really liked the graph on the first page too :)
