Intel Haswell-E Core i7-5960X CPU & X99 Chipset

There are many members of the "1366 X58 Enthusiast Overclockers Club" that have been waiting with bated breath for Intel's launch of the new X99 Express Chipset and new family of Core i7 Haswell-E processors. All this new hardware comes bundled with brand new DDR4 RAM technology packing huge bandwidth as well.

Test System Setup

All processor and memory clocks and timings are identical across all systems (4.5GHz / 1866MHz). This way we can focus on Instructions Per Clock and how much work each gets done. Being overclockers, we know that testing at arbitrarily assigned default clock speeds per processor model tell us little when we know we will not be using the processor at those default clock speeds. When you throw dynamic clock rates into the mix, i.e. Intel Turbo Boost, things can get even a bit more murky.

We also are adding a AMD FX 8-Core Black Edition FX-9590 to our results as we had some readers that were disappointed that we did not have these last time around. I am however NOT adding this system's scores to the benchmark graphs. I am not adding these because these scores tend to heavily impact the graphs' scaling and make it harder to see differences between the Intel CPU products. These scores will be noted in text however for comparison.

All systems are tested with identical component and OS setup with obvious hardware exceptions noted above. Our AMD system was tested at 5GHz while the rest of our systems were tested at 4.5GHz. If you ask why the AMD system is clocked higher, the answer is that it simply overclocks to higher frequencies and should represent a more real world "high end" overclock for the FX-9590 processor.

Also we have added additional RAM speed for our new DDR4 capable system. We are using Corsair's New Vengeance LPX DDR4. We will be seeing RAM frequencies up to 3300MHz or so on this new X99 chipset but do not have RAM that is able to be used at this speed yet.

Currently on the ASUS X99-Deluxe motherboard we are using required us to change the bus speed and strap setting to get 2800MHz DDR4 RAM speeds. This of course gave us a non-4.5GHz score for comparison. We matched the CPU clock rate as close as we could for comparison, so we end up with a 4450MHz clock rate with the DDR4 at 2800MHz. We have been talking to ASUS about this and we should be seeing DDR4 RAM able to be clocked at 2400MHz rates and up without impacting the bus speeds in upcoming BIOS releases extremely soon.

The cooling system we are using is the Koolance EX2-755 (Exos-2 V2) with a Koolance CPU-380i water block that works with all recent generation socket configurations. To adapt this 775/1155/1156/1150 block to your LGA 2011 or LGA 1366 system you will need these adapter posts. The Koolance system did a very good job of keeping our processor temperatures manageable.
