Media Encoding
Handbrake
Known mainly for its DVD re-encoding prowess, our test uses the Handbrake command line interface on a full DVD rip to gauge CPU performance.
Interestingly, the Core i7-3770K runs a bit faster in our Handbrake testing when we disable HyperThreading to simulate the Core i5-3570 CPU; the same is seen with the 2600K/2500 scenario. Still, the new Ivy Bridge processor is faster than the Core i7-3820 and within a reasonable margin of the 6-core 3960X.
x264 HD Benchmark
The popular x264 benchmark available from graysky does a two-pass H.264 encode on 720p video. The first pass appears to be more clock sensitive while the second pass is more heavily threaded.
The first pass shows the same kind of results that Handbrake did – higher performance with HyperThreading disabled. The second pass is very different though as we see nearly a 20% gain in performance by enabling it. The i7-3770K is 16% faster than the i7-2600K and 11% faster than the Core i7-3820 SNB-E.
Now that HD4000 has arrived,
Now that HD4000 has arrived, can OpenCL be used to enhance the performance of the Ivy Bridge processor while simultaneously using a discrete graphics processor? If OpenCL can utilize GPU cycles for general purpose compute tasks then It should be able to utilize the Intel integrated GPU for more general purpose processing power in addition to the Ivy bridge’s other CPU cores, while the discrete GPU uses its resources for the graphics. OpenCL should see all the hardware on the computer as an available resource and It should be able to do this? If not then what is described as Heterogeneous computing has not completely arrived yet! Or is it just a matter of waiting for the software to catch up?
OpenCL does not apply to
OpenCL does not apply to “general purpose” compute tasks. OpenCL applications are extremely parallel algorithms for specialized data sets, there’s nothing general purpose about it.
The “general purpose” in GPGPU simply means “not limited to graphics rendering”.

“And if you happen to be one of those poor fools still using a Pentium 4 processor – will you please save us all the early death of global warming and upgrade?”
Well, i still have one. I’m a PIV (with HT) big fan (smile*).

I recently got a i7 2600k PC with a GTX 680 graphics card. My motherboard is a Z77. Should I upgrade to the i7 3770k ? is the 10-15% worth the money ?
I got a 3770 and I love it!
