Reviews Word on the street for the Intel Core i7 4960X

Multi-threading performance is going to improve modestly, thanks to an increase in non-Turbo base clock speed.

What People Are Saying Give it to me straight

Socket Type

The Asus board is a particularly gorgeous implementation of the chipset, with six USB 3.0 ports in back, dual gigabit Ethernet, integrated Wi-Fi, and support for up to 64GB of RAM across 8 DIMMs.
by PCMag (Sep, 2013)
In the multithreaded test, where the hexa-threaded processors can stretch their legs, the Core i7-4960X scored an 11.13 compared with 10.52 for the Core i7-3960X and 8.18 for the Core i7-4770K.
by PCMag (Sep, 2013)
If you had the misfortune to purchase an Intel DX79SI, DX79SR or DX79TO (boards that retailed for between $219 and $319), you don't get to upgrade.
by PCMag (Sep, 2013)


All tests were run using a SanDisk Extreme II 240GB SSD for primary storage, with Windows 7 64-bit SP1 (all additional patches and updates were installed prior to testing).
by PCMag (Sep, 2013)
In 3D rendering test Cinebench 11.5, the 3960X scored a 1.57 in the single-threaded test, compared to the 4960X's 1.67.
by PCMag (Sep, 2013)
Obviously, PCMark 7 isn't optimized for more than four cores, but that's indicative of the general problem—a great deal of modern software isn't really designed to run at up to 12 threads.

In a core-for-core comparison, Haswell is always going to beat Ivy Bridge.
by PCMag (Sep, 2013)
Typically, adding support for a new processor is a relatively simple affair, particularly when the new chip doesn't introduce new features, core counts, instruction sets, or operating parameters.
by PCMag (Sep, 2013)
Single-threaded performance between the older Intel Core i7-3960X and newer Core i7-4960X is going to be nearly identical, which means we may see the Haswell-based 4770K outperforming both cores in some tests.
by PCMag (Sep, 2013)


Since Sandy Bridge and Ivy Bridge performance were very nearly identical, there's not a lot to get excited about here.
by PCMag (Sep, 2013)
At the top-end part is the hexa-core Core i7-4960X, with a clock speed of 3.6GHz base and 4GHz Turbo.
by PCMag (Sep, 2013)
Split Verdict The value of the Intel Core i7-4960X is much weaker than it had it to be, thanks to multiple compromises on core counts and small clock speed increases.
by PCMag (Sep, 2013)


The L3 cache is 15MB on both models, but the new i7-4960X does support slightly faster memory—quad-channel DDR3-1866 is formally supported, up from the Sandy Bridge-E's DDR3-1600.
