Intel Sandy Bridge E 3930K CPU Review

CPU by leeghoofd @ 2011-12-13

On the 14th of November Intel has shown it's brand new high end platform baptized Sandy Bridge E to the world. Almost all of the press sample kits included only the Extreme version aka the 3960X CPU. Some lucky hardware sites got a 3930K version, with unlocked multiplier, from a 3rd party to test or review. Since this K skew CPU is retailing at only half the price it could become quite a steal. This if it performs alike it's bigger brother. Major difference between the Extreme and the K version is the reduced L3 cache from 15Mb down to 12Mb. Yet, as mentioned before, the multiplier remains fully unlocked, similar to the K skews of the little 2500K and 2600K socket 1155 models, the latter two being heavily popular, as speeds over 4.5Ghz are a breeze. Before continuing with the review : a big thanks to the guys from Tones webshop to supply us with a brand new retail 3930K CPU. Now let's get it on !

Stock Clocks Part II

Let's continue with more actual setups and newer benchmark tests. Leave the older technologies for what they were and give them a well deserved rest.

Fritz 12 Deep Chess test is a regular amongst most benchmark suites. Being heavily multithreaded and very consistent in output. The 3930K outperforming a CPU costing close to double of it's price (when being released) the Gulftown 990X.

The newer Cinebench Release 11 only tests the multithreaded part of our CPUs. Both the SB-E not tolerating any competition and setting new standards.

The POVRay rendering test is totally dominated by the socket 2011 CPUs. Yet the 2500/2600K's are only a few seconds slower. ( Keep in mind the latter were tested on an Asus board, with locked turbo ratio for all cores ! )

In Pcmark05 SB-E is king, while PCMark07 is a close battle. Like mentioned before, plz keep in consideration that the little SB 2500K and 2600K results are boosted by the locked Turbo from the Asus mainboard.

With the FX-8150 review we got a lot of criticism why we still included so many single threaded applications. A partly wake up call for Madshrimps : Multi-threaded is the future ! So we opted to include a multithreaded version of SuperPi. Plus Y-cruncher supports the newer AVX instructions ( Win7 with SP1 required ) giving that extra boost for the AMD FX and SB and SB-E CPUs.

This 3930K is taking a huge leap over the 990X Gulftown Hexacore. It's more expensive brother is a bit faster and double the price... darn these SB-E are really powerfull !

We opted to keep Windows 7 and it's parking core mode stock. Even though there's a nice gain especially in Winrar for the Intel CPUs when disabling this mode. Read more on the topic at Hwbot by mista OBR. Even without, the 3930K can mess with the big boys. Fast faster fastest...
