Intel Ivy Bridge-E Core i7-4960X IPC and OCing Review

We debut Intel's next $1000 Extreme Desktop processor, the Core i7-4960X, this time with Ivy Bridge architecture and a couple of extra cores thrown in for good measure. It is a beast of a CPU for those that can actually harness its power and bandwidth, but how much better is it than Sandy Bridge-E and Haswell at the same clocks?

Gaming Benchmarks

As always, these benchmarks in no way represent real-world gameplay. The graphs show our traditional low resolution approach to using canned gaming benchmarks to highlight CPU differences. All of these are run with a GTX 670 graphics card. We have dropped our Ivy Bridge comparison in our gaming benchmarks due to that test system results being supported with a GTX TITAN video card.

We have recently moved to a GTX 670 GPU which further alleviates any GPU bottlenecks and we are very much seeing our CPU limits.

Yes, this original Lost Planet benchmark is very long in the tooth, but it still remains one of the few game engines that tremendously benefits from multicore processor usage. What I did find out very recently was that it will only reach into 8 threads as opposed to the 12 it identifies. So for all intents and purposes what we are seeing here is only 4C/8T being used on all processors.

Not surprisingly the Haswell processor ends up on top. The Ivy Bridge-E and Sandy Bridge-E show no real difference.

The results here were a bit surprising for us, but solidly repeatable. We have not used Heaven for a long time, and are still getting a bit used to it, but but what we are seeing is not out of place. We see the same scaling below in BioShock Infinite.

As we saw above, the Ivy Bridge-E processor again greatly outshines the Sandy Bridge-E but is manhandled by the new Haswell architecture.

And finally we see the same scaling again albeit a bit tighter in this benchmark that is certainly more graphically demanding even at "low" visual quality settings.
