Core i7-3970X Extreme Review: Can It Stomp An Eight-Core Xeon?

Features
By published

After one year of dominating the enthusiast space, Intel's Core i7-3960X is being replaced. The new Core i7-3970X features higher clock rates, but also imposes a 150 W TDP. Just for kicks, we're putting it up against another 150 W CPU: the Xeon E5-2687W.

World of Warcraft: Mists of Pandaria is also sensitive to processor performance, rewarding Intel for its multi-core designs, large caches, and aggressive Turbo Boost settings. Meanwhile, the average frame rates achieved by AMD’s CPUs trail off rapidly at 1680x1050 and 1920x1080. It’s really only when you’re at 2560x1600 using 8x MSAA and the Ultra quality preset that the Bulldozer- and Piledriver-based FX processors perform comparably.

    100mhz faster than the 3960X, not worth the extra premium.

    Same thing goes for the 3960X compared to the 3930K....not worth the extra 100mhz for $400....

    Boo on Intel for not enabling all 8-cores especially at that price!

    I've recently started facepalming every time I see BF3 in CPU benchmarks. "Boy oh boy, this hasn't been confirmed like a hundred times already but the single player is decidedly graphics-bound, so here, have these charts with identical results anyway."

    jaquithBoo on Intel for not enabling all 8-cores especially at that price!They don't have much of a choice when it comes to the i7's. With the 32nm Sandy Bridge-E Intel has to make a choice between prioritizing clocks or core count within a 150W TDP, based on the target workload for a particular processor. For Xeon's the choice is easy, more cores. For desktop applications the choice isn't as clear, but I think most users would still benefit more from a higher clocked 6-core than a lower claocked 8-core. That's slowly changing though.

    Intel also doesn't want a situation where their LGA 1155 processors outperform their $1000 extreme edition in lightly threaded workloads, which is yet another reason to favor 6-core for now.

    I'd personally like to see an 8-core i7, even if it means lower clocks, but I don't think that'll happen until Ivy Bridge-E. At 22nm Intel probably won't have to make a choice, we'll get the best of both worlds.

    Why do people still benchmark on itunes 10.4? 10.7 is out... as for the 8 cores as said above^, there is no need to have more than 6. Because if it had 8, then xeons would not sell to pros.

    Why are we not manually overclocking this expensive CPU? Why do we do benchmarks against stock ig 2500k?

    You also forgot something when comparing against Xeon:

    Stability test.

    Run the i7 for one month under Prime95. It will crash. Run the Xeon for one month under Prime95. If it crashes, then you got a defective Xeon because they're not suppose to crash under 24/7 workload.

    Why would you even include the 8350? It is 1/6th the price of this CPU. I couldn't imagine what a modern AMD desktop CPU would consist of at the $1000+ price range.
