SB and Video Encoding

[Claudius-07]

I currently have few rigs which I use for encoding. I am trying to actually quantify the difference it takes from a full DVD to a x264 conversion using Handbrake. I see benchmarks etc that show bar graphs etc... but I cannot seem to find something that says... ok it takes you THIS much on your current rig xxx if this is what you have and if you get a 2600K and OC it to 4.8Ghz, it will take xxx time. For someone who does hundreds of encodes a week, whether for work or for personal use, just trying to see if it's actually worth it.

Does Handbrake take advantage of anything special with SB? Would you need to use a different program to get full benefit from SB. I bought and paid for DVDfab... which i also use at home only -- with the CUDA acceleration that is something else.

My work computer is a 980x but that is not OC'ed... so stock... would there be ANY benefit in getting a 2600K and oc'ing the crap out of it? SB vs 6 core 980x? again strictly for video encoding... not gaming or anything else. Is there some sort of formula someone can give me say 1:1 or 1:1.05 etc? I know I am asking the world here.

My rigs have either 12GB of RAM or 16Gb. All have SD drives for OS and SD drives for working drives where I also do lots of Photoshop and Illustrator. Thus other than encoding, it's all i do. Is SB the way to go or should I be doing something else? We frown upon OC'ing at work but maybe you know.. we can work something out -- heck we don't even use GPU acceleration for conversions so it's why I am asking.

I have mine oc to 4.3. Name a couple of movies that you have let me know what setting you use and i'll encode and let you know how long it takes.

Sandybridge has die function called QuickSync that uses fixed function hardware and the integrated GPU for de- and encoding.

See:

http://www.anandtech.com/show/4083/...-core-i7-2600k-i5-2500k-core-i3-2100-tested/8

+ following page

Important is that the used software must support the feature and that you need a H67 Chipset + actually use the integrated GPU for display, eg. no discrete GPU pssible, if you want to profit from this.

For CPU only encoding your 980x is still the faster than a 2600k. I mean you can see how many FPS each CPU gets and from their you can calculate the same for every movie if you know it's playtime and frame rate (usually 23.9...fps)

Handbrake is slow. Better software will be a better investment than a new cpu.

Going by these x264 benchmarks, an i7-2600K at stock is almost as fast as a i7-980x in video encoding. Overclocked to 4.0Ghz or higher, that SB should have no problem outrunning the i7-980x.

Does Handbrake take advantage of anything special with SB?

The only thing that would really be relevant is the new AVX engine on SB. Doubtful Handbrake takes advantage of this as it requires a rewrite of the code. Although, anything that uses the SSE engine (like video encoding) on SB will be a good jump faster than on the previous generation CPU's -- probably ~ 20% faster.

As for overclcocking SB, with a K model (unlocked) processor you could likely clock it to at least 4.0Ghz at stock voltage settings simply by turning up the multiplier.

Wrong, it only requires a screen to be plugged in to the motherboard graphics ports.
