BD-Rebuilder speed with and w/o overclocking

[SLOVEHEART]

I have a Asus mobo (P6T WS PRO) that has 'Turbo V' - it is a utility which allows one to make overclocking profiles and turn them on or off at will. So, usually I run my Core i7 950 @ 3.06 (stock) but when using BD-RB and other apps - I can o.c. to 3.515 if I want to.
Here is a comparison between recodes using BD-RB to make a DVD9 from a BD25 disc (20 GB) - one run was with o.c.'ing and the other - stock.

Both runs had Multi-channel audio and stereo tracks (on main streams), encoding was done at high quality. BD-RB and operating system are on C: (10000rpm Velociraptor 300GB) and source files were on D: (Seagate cheetah 15000rpm sas 300GB) and output was to E: (another cheetah sas drive(same as d: )).
---------------------------------------------------------
First Run (O.C.'ed 3.515GHz):

Start: 07:05:12
Finish: 10:21:28

Total time: 3:17:16 or 11,836 sec (you'll see why secs later)
--------------------------------------------------------
Second Run (Stock 3.06GHz):

Start: 10:26:57
Finish: 14:10:14

Total time: 3:43:17 or 13,397 sec
--------------------------------------------------------

Difference of 26 Minutes 1 Second or 1561 seconds.

Analysis:
----------
CPU O.C. = 3.515
CPU = 3.06

3.515 / 3.06 = 1.148693 (Ratio of CPU speeds)
----------
Taking O.C.'ed time in secs (11,836) times (Ratio of CPU speeds) = 13,596 seconds - This is very close to actual time for time for run w/ no O.C.'ing (off by 3min 19secs or 199 secs).
----------
Or - take time not O.C.'ed - divided by time for O.C.'ed
==> 13,397 / 11,839 = 1.13189 Very close to Ratio of CPU speeds (1.1486).

In any case - the overclocking is a nice time saver - and is almost linearly connected to CPU speed(s).:)

Wow. A high-quality mode encode done in a little over 3 hours... I really need to upgrade my system.

JDOBBS:
Yeah, I just built this rig - I use to take 10 hours on a vista 32 bit with a Q6600 quad core and 4 GB 6400 memory - and a standard Sata HD (7200 RPM) ...

you of all people should have a nice rig...It put me in the poor house - ha...poor poor but fast rig - some folks would o.c. this to 4 GHz...

Imagine what 10 GHz would be like - maybe nitrogen cooled...:thanks:

Note if memory:CPU divider ends up being a bottleneck, it's often useful to slow down the memory to speed up the CPU, since x264 tends to not be too memory-bound.

Hi,

Have you also enabled Hyper-Threading?

I have read a number of benchmarking tests with X264 and having hyperthreading turned on can improve your encoding by 10-20%. I have always had it turned on from when I first built my system so I haven't measured the actual performance increase, but if you haven't turned it on already, it would be interesting to see what you experience. All 8 threads are generally 100% utilised during the 2nd pass.

I have an i7 920, and whilst I generally haven't OC'ed in the past, I have mine running at 3.5 Ghz also (not a bad increase from the stock 2.66 Ghz). I used 1333 Mhz DDR3 (instead of 1066) and set base BCLK frequency to 167 Mhz (instead of 133 Mhz) and kept TURBO mode enabled, whilst keeping all the voltages at stock. It is perfectly stable, and I haven't had any issues in the past 9 months.

So the i7 920 might be a value proposition for someone using BD-RB.

YES I hyper-threading enabled also - and I checked the CPU affinity for BD-RB to make sure it is using all 8 threads ('cores') - and I am happy with the 3 Hr recode time for 20GB BD to DVD9 - whereas it took 10 -11 Hrs for my Hp from hell with a Q6600 and Vista x86 - yow.

My BCLK is 155 - up from 134 (or 133) and I have all voltages stock too - I ended up with 3.515 - any increase beyond that requires an increase in voltage and that sends the temps up 20 degrees celcius - even with a corsair H50 (Hydro - cooled) CPU cooler - I don't want to deal with the high temps - I'm happy with things at mild O.C. - the other reply is an idea - I made a dumb decision to use 12 GB of memory - all 6 slots are filled and therefore my timings are 2t instead of 1t - I think I'm going to pull out two sticks and go with Asus's 4 stick option so I can have better memory timings - my understanding is the change from 1T to 2T is a significant decrease in performance.

Same system and same clocks and it just blows my mind how much faster it is han my other machine (Q6600 at 3.00GHz). Anyone using BD-Rebuilder a lot should have an i7 based system. The 920 OC'e is a great option if you're willing to take the time to get it stable.

[ricoman]

I have an i7 920 at the stock 2.66 speed, 6gig 1333 3 channel and it takes me 4-5 hrs. for a movie only to DL disc. I still just run it when I go to bed so cutting an hr. off is no big deal to me. But I have to admit that when all 8 processors pop up and are running, it's pretty impressive.:cool:

[jfcarbel]

Can anyone post their encode times with the newer i7-2600/2500 procs or for the i7 980x.

This thread should get real interesting when the newest Intel six core cpus come out in the fall. I wonder if we will be able to get down to 1 hour for an encode.

From all the threads I have read here it seems the 3 hour mark for the i7 920 has been the best. Although someone here has a i7 980x six core but had not posted the encode times and I assume its much better then 3 hours.

With my Q9550 at stock 2.83 I am getting 6-7 hours for BD50 to BD25 encodes.

[Groucho2004]

Comparing encoding times with different video sources and encoder settings is pretty meaningless.

If you want to see comparative results, have a look here (http://www.techarp.com/showarticle.aspx?artno=669&pgno=5).

I wouldn't go as far as saying they are meaningless, but yes I agree for a more exact and reliable method the benchmarks are best.

However, I do think there is some value to the numbers quoted in this thread. That is, how long will a comparative system like mine take to encode a BD50 to BD9 VC-1 movie. However, they should serve as an information guide and not taken as a reliable benchmark. But I think the more people posting in this thread the more reliable of a guide for BD-Rebuilder encodes they will become. LOL, in fact, I think jdobbs in seeing that system with the 3 hour encode inspired him to upgrade his system or at least gave him some motivation to remind us about donations ;) :sly:

But folks should realize they are ballpark figures. One should of course comment on any other of their system variables that may effect overall speed such as using an SSD, OS version, etc. But I think you will find that most of the values for a certain processor based systems here will tend to be about the same maybe someone with exception will have something wrong with there system config/OS and will have very off times as did the one person in the prior thread to this one. I think a variation of +-30 minutes is probably most likely when looking at these results. And this could just be the material being encoded even if 2 systems are exactly the same. So it should only serve as a guide. In fact it did help me to discover I had a performance issue and to investigate, but I did use the x264 benchmark when making system changes to check if changes helped. Turned out the Toshiba UDF 2.5 driver did not like my system and caused some significant performance issues when encoding.

So I will add this to my request, along with posting your ## of hours to an encodes , also post the x264 benchmark (http://www.techarp.com/showarticle.aspx?artno=520&pgno=0) value for your system as well. Also indicate type of BD-Rebuilder encode (i.e BD50->BD25 VC-1, BD50->BD9 AVC, etc), your OS type (i.e. Win XP 32-bit, Win7 64-bit), whether using an SSD or not, and any other system effecting variables. Also indicate if you follow the best practice of separate drives for source and target.

I will run a benchmark now and post my results below on the thread along with my BD-Rebuilder encode times to provide example format.

[Stereodude]

FWIW, you really need to pick a benchmark movie and have everyone compress it with the same settings. Then you can compare results and draw valid conclusions all you want.

Wow, if an i7-2600k @ 4.3 GHz proc. can do an reencode in 1.5 hrs, it should be interesting to see what the Intel 6 core CPU (http://wccftech.com/intel-sandy-bridgee-processors-launching-november-15th/) and AMD Bulldozer FX processors due on 11/15/2011 can do.

The Core i7 3930K features 6 Cores/ 12 Threads, An Unlocked Multiplier, Stock Speed of 3.20Ghz (Turbo – 3.80Ghz) and 12MB L3 Cache. The official pricing of the chip at launch would be 560US

TDP 130W (this suckers are hot, probably need water cooling to do a good OC)

Anyone here planning any computer upgrades to these procs?

[jfcarbel]

Ok, revisiting this thread as I am pondering an upgrade to Core i7 3820 on X79 platform.

Anyone have comments on average encode times from most BD50-BD25 (also post your x264 benchmarks if you would)?

have seen that the 3820 can perform better then the 2600K so I am wondering if we can get encode times below or at the 1 hour mark.

Here is what I am looking at:

Core i7 3820 LGA 2011 Boxed Processor
Asus P9X79 Pro Socket 2011 X79 ATX
128GB Samsung 830 SSD Sata 3G
Coolermaster Hyper 212 EVO

Not yet sure about jumping in just yet as both Asus and Gigabyte seem to be having bad QC issues on their X79 boards.

With that cooler I should be able to reasonable OC to 4 Ghz. So 8 threads at 4 Ghz and I bet x264 really performs well :)

I am wondering if we can get encode times below or at the 1 hour mark

Keep in mind, though, that most of the benchmark reports, including the i7-2600 1.5hr encode (2011.07.25), seem to use a "good" quality setting, while your report (2011.10.17) shows the quality level to be "high". This makes a big difference.

For instance, I did "Tintin" the other day. High quality, 2-pass, including audio re-encode. My system is an i7-950 running at 3.6GHz. Total time 4 hr 14 min.

I just repeated the same disc. Good quality, 1-pass ABR. Total time 62 min.

I just don't want you to spend a large wad of cash expecting that your current encode times of approx 7 hrs are going to drop to 1 hr. They will be faster, I'm sure, but not likely that much faster.

For instance, I did "Tintin" the other day. High quality, 2-pass, including audio re-encode. My system is an i7-950 running at 3.6GHz. Total time 4 hr 14 min.

I just repeated the same disc. Good quality, 1-pass ABR. Total time 62 min.

I just don't want you to spend a large wad of cash expecting that your current encode times of approx 7 hrs are going to drop to 1 hr. They will be faster, I'm sure, but not likely that much faster.

Thanks for pointing that out I did not even notice that. I am due for a system upgrade (also do lots of video editing) and have some gift cards to use. But any upgrade from my older quad will be significant enough to make me happy. If I can halve the time I would be very pleased. But yes 1.5 hour encode did seem like nirvana. I prefer though to do the high quality since most encodes are set for overnight anyways.
