**LETS SEE YOUR PILEDRIVER OVERCLOCKS - LET ME START WITH 5GHz+!!**

TL DR : Encoding settings can tip the scales.

How many versions do you want me to use here.
I gave up using the 0.9.x series and use the nightly builds now.

Reason is they have sorted out the thread usage and i get 100% on 12 cores on the SB-E's.
A 50% increase in speed.

Doesn't make a difference to me, run the one that can take an FX83 to 100% though.

Hoping that will load the PD up nicely.

Is it possible you could run the latest release(0.9.8) and the latest nightly??

I think I remember someone mentioning the issue you were talking about in that thread too.
 
The Open CL version is closed to all but a few insiders.

The nightly builds are available to all.
I cant be sure which version of the nightlys had the fix in use more threads as i only recently discoverd them.

anyhow PD is running 99 - 100%.
Windows 8 task manger is strange it takes a few mhz off the actual cpu speed.
 
Cyberlink Power Director uses the OpenCL on the GPU, and it works well.

But, the speed increase is not massive, its significant, something like 30 or 40% on my 7870 vs the CPU, don't quote me on that as have never actually timed it properly.

Also the picture quality just isn't the same as HB, its not as good, be it on the GPU or CPU.

Its also not cheap, progy like this are very pretty, also easier to use than HB, but HB is just better, much better.

OpenCL is really coming into its own, i use it for Adobe CS6 as well, supper quick....

Handbrake svn5081
Source Blueray rip 37.2Gb Length 02:49
Normal Preset RF20 h264 codec mkv output file

IVY 3770K 4.6Ghz
average encoding speed for job is 76.383286 fps

PD FX8320 4.6Ghz
average encoding speed for job is 72.085876 fps

close
Humbug gets the cigar.

edit:
An encode using the high profile preset with RF set to 18 higher quality.

Handbrake svn5081
Source Blueray rip 37.2Gb Length 02:49
same rip as used in previous test
High Profile Preset RF18 h264 codec mkv output file

IVY 3770K 4.6Ghz
average encoding speed for job is 18.726086 fps

PD FX8320 4.6Ghz
average encoding speed for job is 18.854017 fps

The tables are turned a win by a short head for the PD

I may get round to testing it.
At the moment i am interested in what happens when i lower the RF level.
I may lower to 18 and use high profile preset,

Thats given them something to think about.
Hope neither of them overheat.

3hr encode

That said, I recall someone posting that they couldn't fully load their CPU with handbrake? (Haven't the foggiest who it was, and I think it was with a 3930k?)

Quite possibly me!
Although apparently it's cuz I was only converting a DVD Rip and you need a Blu-Ray rip at high quality to fully load it.

Would a PD 8320 or 8350 be a decent upgrade from a 1055T @ 3.5GHz?
What's an average, conservative, PD overclock?
 
Hmm, 5% faster for 38% more cash. I suppose that's always been the way with the highest end stuff. Like the top end GPUs, extra cost not equal to extra performance.

Still, my 8320 does 4.6ghz easy and that's 46% less cash. 3770k will do 5ghz though with the same cooling yeah?

No 3770K will not do 5Ghz.
It will in very short bursts but sustained 4.6 is all she wrote
 
Show me one finish a long encode at 5Ghz.
Only sudicide runs at 5Ghz on any CPU you should know that.

If you want a PC that actually finishes what it started then 4.6Ghz is about MAX.
IVY's are peculiar in that it doesn't matter what cooling you use.
They cant disipate heat quick enough out of the core.

Water, top end air doesn't really matter as the voltage required for stable running at 5Ghz just roasts the core.

edit: this high profile encode i am running is too close to call only .1 FPS in it.
Still a way to go yet 2hrs + but the PD is hanging on in there. .1 ahead

does anyone fancy doing a proper table of benchmarks for ocuk ?

so basically we choose the relevant benchmark progs we do them and all submit our details

this would be quite useful

someone knock up a table with results

I can do that, I'm pretty capable of making up tables (see pic) and i still have a Thuban BE in my rig which is a useful yardstick for Vishy.

Have to be quick tho because its going soon.

Anyone want to make a suggestion of Games and app's to bench? and i can get on with it.
