Visual Studio Compile
Our compile test is back and better than ever. With a much larger and faster SSD (Samsung SSD 830, 512GB), we're able to get more consistent compile times between runs. We're now using Visual Studio 2012 to compile Mozilla's Firefox project. The compile is multithreaded however there are periods of serial operation where performance is bound by the speed of a single core. The end result is a benchmark that stresses both single and multithreaded performance. Compile times are reported in minutes elapsed.
It's clear that IVB-E holds the advantage over Haswell when faced with heavily threaded workloads, but what about those workloads that are a good mix of both light and heavily threaded tasks? A medium-threaded workload if you will. It turns out our Firefox compile test is just that. Haswell's architectural improvements seem to do wonders for this test (under OS X as well), giving the 4770K a 16% lower compile time than Ivy Bridge. IVB-E on the other hand throws more cores at the problem, effectively equaling Haswell's performance but not exceeding it. In this case, if the rest of your applications are better threaded/demand more cores then IVB-E is the right solution for you. If, however, building Visual Studio projects is the most thread heavy thing you do then Haswell is a better option.
Photoshop
To measure performance under Photoshop CS4 we turn to the Retouch Artists’ Speed Test. The test does basic photo editing; there are a couple of color space conversions, many layer creations, color curve adjustment, image and canvas size adjustment, unsharp mask, and finally a gaussian blur performed on the entire image.
Time is reported in seconds and the lower numbers mean better performance. The test is multithreaded.
Our Photoshop test provides another example of an application with both lightly and heavily threaded behaviors. In this case, our Photoshop test favors the latter as the 4960X manages a 13% performance advantage over the 4770K. Once again the IVB-E advantage over SNB-E is around 5%.
File Compression/Decompression
The 7-zip benchmark is a CPU bound multithreaded integer workload that looks at 7-zip compression/decompression algorithms where the IO subsystem is removed from the equation:
In its biggest advantage so far, the 4960X outperforms the 4770K by 56% in the 7-zip test. The IVB-E performance advantage compared to SNB-E shrinks to under 3% here. Heavily threaded integer workloads are also well suited for AMD's FX architecture. Here the FX-8350 is able to equal Haswell's performance.
Next up is our old Par2 test. Par2 is an application used for reconstructing downloaded archives. It can generate parity data from a given archive and later use it to recover the archive. Chuchusoft took the source code of par2cmdline 0.4 and parallelized it using Intel’s Threading Building Blocks 2.1. The result is a version of par2cmdline that can spawn multiple threads to repair par2 archives. For this test we took a 708MB archive, corrupted nearly 60MB of it, and used the multithreaded par2cmdline to recover it. The scores reported are the repair and recover time in seconds.
Here's another heavily threaded workload that does very well on the 4960X. We also see a rare situation where IVB-E increases performance over SNB-E by more than 10%.
Excel - Heavy Math
In our final CPU centric test we're running a monte carlo simulation on a large Excel spreadsheet. The process is well threaded.
With 50% more cores, the 4960X delivers 33% better performance than the 4770K. If running multithreaded math workloads is up your alley, there's no alternative to the 6-core extreme edition parts.

How does Intel's closed-loop cooling package compare to say, Corsair's or other similar products?chizow - Tuesday, September 3, 2013 - link
Probably within 1-2C of similar "extra wide" 120x37mm closed-loop coolers. Looks like Intel's solution is made by Asetek going by it's block and mounting design, so I'd compare it against the Antec 920 for starters.Samus - Tuesday, September 3, 2013 - link
Still running i7-950 system (was an i7-920 back in 2008) and all I've upgraded since building it is a small bump in CPU speed, added water cooling, and installed two GTX660's in place of two GTX460's installed in 2010, which replaced the Radeon 4870x2 from the original 2008 assembly date. I've also replaced the original 500GB Seagate Boot Drive from 2008 with an Intel 160GB X25-M in 2010. Still use the same SSD to this day.Same motherboard, same 6x2GB G.skill DDR3-1600 modules (that cost $600 back in 2008) and same PC Power & Cooling 750-QUAD.
I've added a USB 3.0 PCIe controller as well.
Overall, this is the longest (5 years) I've ever owned a system that retained the same motherboard. The irony is Intel discontinued Socket 1366 so fast it wasn't even funny. It was actively supported less than 2 years, and only 2 generations of chips (using the same architecture and process) were made within a year of each other, essentially giving this socket a 15-month lifetime.
But 5 years later, a system built on this socket is still faster than 90% of the production systems today.

Yeah, for 1366 owners, there's absolutely no reason to upgrade, especially with overclocking. At least you got one generation of upgrades, unlike 1156 owners who got completely screwed.P.S. The second gen upgrade on 1366 (Westmere) was a new architecture and process. They shrunk down from 45nm to 32nm and added AES instructions.

I'm a current 1156 socket owner running I7 875K @ 4.2. My rig is still running strong, but I'm ready for an upgrade. Just purchase a 4960x with 16 gig of Corsair Dominator Platinum at 2400 and the Asus Black Edition mobo. Hope the spending is worth it.evilspoons - Tuesday, September 3, 2013 - link
What does this have to do with chizow's comment about the closed-loop cooler??JPForums - Thursday, September 5, 2013 - link
Absolutely nothing. I'm guessing it was just an easy way to get posted near the top.
If I recall correctly, the 920 is 49mm thick. Also, I've found that fan selection can make more than a little difference. I would not expect the Intel cooler to match Antec's 920, given their history of racing to the bottom with cooler components. That said, it should beat the 620 and similar 120x120x25mm closed loop systems (assuming they didn't screw up the fan selection in epic manner).

I run a i7950 at 4.07 ghz with a overclocking thermaltake cooler, 3x 580's and 12 gb ddr, am now upgrading to the i74960x, thermaltake water 3.0 and 2 x asus gtx 780ti sli, 32 gb ddr3. the old rig is still going strong and will use it for a simulator pc as i have a g27 sitting doing nothing. Great machine and has served me well!~foursixty - Saturday, April 5, 2014 - link
just might add for the asus sabertooth x79, i74960x, 32gb 2400 ddr3, and 2 asus gtx 780ti oc cards is a $4000 upgrade, been doing a lot of overtime so i thought i would update while i got the extra cashjust4U - Friday, September 6, 2013 - link
Corsairs closed loop and Intel's appear to be built by the same company.. Some of Corsair's earlier attempts were noisy whereas you didn't really have that problem with Intel's. Overall I think it's a pretty solid contender with very few faults. There is better on the market obviously... but it's decent for it's price.
