The Tech Report took the new i7-5960X, Asus X99 Deluxe, 16 GB of Corsair Vengeance LPX DDR4, a Kingston HyperX SH103S3 240GB SSD and a XFX Radeon HD 7950 DD and set it loose on the test bench.  The results were impressive to say the least, especially when they moved on from games to test productivity software where the Haswell architecture really shines.  When they attempted to overclock the CPU they found a hard limit feeding the processor 1.3V and running 4.4GHz, any faster would cause some applications to BSoD.  On the other hand that applied to all 8 cores and the difference in performance was striking.

Also make sure to read Ryan's review to get even mroe information on this long awaited chip.

"Haswell-E has arrived. With eight cores, 20MB of cache, and quad channels of DDR4 memory, it looks to be the fastest desktop CPU in history–and not by a little bit. We've tested the heck out of it and have a huge suite of comparisons going to back to the Pentium III 800. Just, you know, for context."
