Intel Core i7 4960X Review


Intel Core i7 4960X Testing:

Testing Intel's latest Extreme Edition processor the Core i7 4960X will involve running it and its comparison products through OCC's test suite of benchmarks, which include both synthetic benchmarks and real-world applications. The gaming tests will also consist of both synthetic benchmarks and actual game play, in which we can see if similarly-prepared setups offer any performance advantages. The system will receive a fully updated, fresh install of Windows 7 Professional 64-bit edition, in addition to the latest chipset drivers for each board and AMD Catalyst drivers for the XFX HD R7970. To ensure as few variables as possible, all hardware will be tested at their stock speeds, timings, voltages, and latencies, unless otherwise stated. Turbo Boost will be disabled on all processors to make a fair comparison without skewing results. After stock speed testing, each processor will then be overclocked as much as possible, while still maintaining full stability.


Testing Setup: Intel Socket 2011

One would figure that overclocking IVB-E would be the same as overclocking a standard Ivy Bridge architecture processor in that it is pretty simple to get to the level of performance you want with a simple bump in the bclock multiplier and the associated voltage needed to stabilize the overclock. In its simplest form that holds true. We do get the bclock gear ratios first offered on Sandy Bridge Extreme and this chip was able to use the 125MHz ratio without any major concerns other than verifying your memory clock speed before a reboot to prevent a failed post due to running too far outside the capabilities of the installed DRAM.

The sample I have here was able to reach 4444MHz, but to do so required much more voltage than I would like at 1.42v set in the BIOS while using High LLC. This required a switch from the Corsair H100 to a full on water cooling system to manage the thermal load put out by six cores under load. On Intel's 22nm architecture that's going to be a bit high for daily use. However it is what is needed to keep the processor running at that speed. Memory overclocking seems to be on par with the 3770K running my test system memory at over 2400MHz with some tweaking to the timings and voltages needed to run the number.




Maximum Core Clock Speed:

Each CPU has been tested for stability at the listed overclocked speeds. These clock speeds will represent the level of performance shown by the overclocked scores in the testing.
