Sandy Bridge-E Benchmarked: Intel Retains the Performance Crown
Cyberlink
For our CyberLink Espresso 6.5 test, we take the same 1920x1080 MPEG2 file that we use in our Main Concept Reference test and convert it to an MPEG4 file suitable for viewing on an iPhone 4. CyberLink Espresso has the capability to be run on a GPU, the CPU or Intel's QuickSync technology that's only in the Sandy Bridge processors. The score is how long it takes to run in seconds. The Core i7-3960X is again the winner (tired of hearing that yet) but not by an overwhelming amount when compared to the Core i7-990X.Oddly, the FX-8150 is the slowest chip of the pack as it just barely trails the Phenom II X6.

As part of our test, we also shifted the workload from running on the CPU to the GeForce GTX 580 that we used in all of our test rigs. We figured since the work load was shifted to the GPU, the scores should all be the same but surprise surprise, the Core i7-3960X comes in significantly faster than the other chips here. We're really not sure why, but when talking to CyberLink about why we're seeing the performance spreads, we are. For kicks, we also ran it on the Core i7-2600K's integrated graphics chip using the QuickSync technology. These are specific hardware instructions that Intel has set aside for video transcoding and encoding. The result using QuickSync was interestingly faster than all of the CPUs save the Core i7-3960X and the GeForce GTX 580. So maybe integrated graphics doesn't suck anymore, does it?

Far Cry 2
For our gaming testing, we like to run our games at low resolutions and with features turned down so as not to bottleneck the CPU with the GPU. This would simulate what kind of performance you would get if you had a fantasy GPU that you somehow snatched out of the year 2015 to run in your machine today. With Far Cry 2 the Sandy Bridge E again runs away with it. We suspect the large cache and memory bandwidth help the Core i7-3960X zoom past all others here.

Handbrake
For our Handbrake test, we used a video file shot with a Canon EOS 5D Mk II at 30fps (the 24fps firmware wasn't available at the time) and tasked Handbrake with encoding it to H.264 using the high profile setting. Handbrake is a widely used free encoder that favors using the CPU for encoding due to the consistent quality over GPU encodes. The Core i7-3960X again leads the pack by an impressive healthy margin over the six-core Core i7-990X chip. The eight-core FX-8150 also holds up its head when compared to the Core i7-2600K chip. We say this despite the Core i7-2600K being a four-core chip with Hyper-Threading because of the pricing of the lower pricing of the FX-8150.

Intel Burn Test
In looking for a benchmark that uses the new AVX instruction set in the Sandy Bridge and Sandy Bridge E cores, we came across the Intel Burn Test. Created by, ummm, AgentGOD at XtremeSystems.org, it's intended as a stress test but it uses AVX to perform linear algebra calculations. It's apparently based on Intel's own Linpack math library thus it's called the Intel Burn Test. As such, we ran it mostly to compare the Intel procs.

Looking at the chart, the Core i7-3960X demolishes the competition but the Core i7-2600K also does pretty well as it also has the AVX instruction set aboard. Despite it having six cores, the older Core i7-990X lacks AVX and is easily eclipsed by the Core i7-2600K part. We did say that we ran this to gauge the Intel parts, but the FX-8150 also happens to feature AVX instruction set support as well while the Phenom II X6 doesn't. Obviously, this is an Intel test but the overall performance of the FX-8150 does pretty well compared to the Core i7-990X and especially against its older sibling. AVX support in applications is in its infancy today, but as with all instruction sets, expect that to expand.
