Testing HyperThreading in TMPGenc ***updated Mulittasking test*** A must see **added test 1/10/2004**

[Duvie]

Added MP3 and AC3 testing with Besweet with HT on,HT off, 1 instance and 2 instances.....

VERY Nice work Duvie. Impressive results too, I must say.

I'm never going back to non-HT for myself ever again, that's for sure. No joke! Hyperthreading isn't essential for people that don't do a lot of multitasking, but I know for me, being able to do a lot of stuff while I burn DVDs/Encode a movie/etc is very important. HT eliminates all system hiccups and minor stalls that even 2-3 GHz P4's and AMD Athlons are prone to on occasion.

There is only one solution for AMD and I seriously hope they take this path: integrate Hyperthreading in their next CPU. It's just that simple. I am a bit of an AMD fan for the singular reason that I like there to be competition in the CPU market, and right now I can't see myself using a non-hyperthreading CPU on a daily basis. Ergo AMD is in a bit of trouble, vis-à-vis their single-threading CPU. Concurrently their 64-bit CPU's prices are a bit of an anomaly for a non-HT CPU ... (sorry, too much Matrix for me! I'm busy watching a DVD while surfing the web and burning a CD ).

I can't agree with you more. If only the two would swap technologies (HT for 64bit instructions) we could be on another significant jump in performance. The only reason I say the AMD 64 bit is so it will be faster to market with 64 bit apps rather than having to code ofr two seperate one's. I do believe however that Intel has something up their sleeve in time for a Holiday launch.

You guys are the reason I am doing this to show the advantages...taking an OLDFART montra I have avoided synthetic (worthless in many ways) benchmarks for tangible real world apps....

Stay tuned I am working on my CADD and Rendering test as we speak....


Anyone who can go to this page with a broadband line and download these files and mail them to me I will pay paypal top do it....56k just doesn't cut it...

Spec Dwonloads for Rendering test

Duvie, I can download that and put it on CD. Is there anything else you would like on it? Maybe UTdemo and patches. I would need the info on where to get the UT stuff. If you need more than one CD I have quite a few DVD -R's laying around.

 

[Duvie]

If you can get the UTdemo stuff that would be great...Talk to shimmishim he has the links to all of them and the utilities....

Thanks!!!Let me know what I owe you for dvd and postage!!!

I will get it out by Wed..

Does that surprised you? I'm not real surprised... well... maybe a little surprised that the temp only increase by 3C at load, and that you're only getting about a 20% increase in performance when you're able to run 2 threads at the same time. I would expect something more along the lines of 50-75% ... but maybe my expectations are too high.

BTW... if no one else delivers on the CD full of broadband goodies, let me know, I'll fill a couple CD's with a bunch of crap you can play with =)

you dont even get that with dual cpus.... why would you get 50-75% out of HT?

 

[orion7144]

Duvie, which files on that site do you want?

 

[orion7144]

Can someone give me a good link were I can download the demo patches for UT2k3. All the one's I tried were dead.

Ya know what, I might be wrong about those SETI times... I've been looking for the thread I'm thinking of, and can't find it, but I did find this one... The best system that I have run for total wu's per day completed is my 2.6C rig @ 3.4Ghz with HyperX PC3500 running at DDR420 CL2-2-2-5 Performance Mode Enabled. With HT enabled it would yield 18-21 wu's per day running 2 instances of Seti Driver at once.

There was this thread over@bleedinedge, impressive numbers jhites is turning in

 

[alexruiz]

Duvie, how long is the movie? I can see you spend a lot of time with TMPGEnc..... for ultimate quality, do you go 2-pass or CQ? If I use CQ, I am better setting a high Q number but lower max bitrate, or the opposite? (Let's say CQ85 max 6500 vs CQ75 max 8000)
What average speed are you getting (fps)? Just an estimate

Congrats!

Alex

Mine easily does 12 WU's per day... I'd say I average about 2 hours even... sometimes it's more, like 2:15, but I've seen some as low as 1:40 and 12 seconds. Is there a way to record the time it takes to complete every WU with SETI Driver? I guess that question might be more appropriate to ask in the DC forums.

Interesting results. I'm hopeful we start to see multi-core on a single die.

Actually, I think Jeff is referring to the large benefit of HT for SETI. Using a single instance does 1 WU every 150min, with 2 instances, each instance processes 1 WU every 165min, or effectively 82min per WU, which is a massive gain. Most likely, the cause of this gain is due to the relatively poor coding of the SETI client, resulting in stalls that slows down the performance with 1 instance, but ironically enables opportunities to better utilize the P4's execution resources with 2 instances.

Actually, it is likely related to how Seti@home is written. I have noted this behaviour many times before, even on non-HT systems (I've even mentioned it before on a few boards). On my Athlon XP 2000+, Seti on Linux would do one WU in ~4:15. With two running, it would finish 2 in less than 6:00, meaning that for an extra 1:45 I could have two WUs completed. I noted similar behaviour on Dual PIII/933 boxes (running 4 processes only took about +50% longer). +50% seems to be the delta for non-HT processors.
It's still good to see that HT makes it +90-95%. It isn't necessarily only a benefit of HT, but more of simply how Seti is written. If you ask me for an explanation, I haven't got one. All I have is observed behaviour. HT should give that difference a great boost simply because of it's half multi-threaded capability.

EDIT:
By the way, just as a point, it's not as if HyperThreading is new anymore. It's not like "today's apps" weren't expected to already support it. After all, it was almost a year ago that Anandtech put out its article on the P4 3.06 w/HT.

For such a touted feature, I'd expect to have seen more games making use of it.

Good stuff!!!


I would like to say what is truly sad is how piss-poor all the review sites have been about HT...It only seems like new information cause the hardware sites still have not done a decent test of HT to tout its benefits....Many rumors persist 1) It can be only seen in synthetis benches and does not help in real world apps; 2) It like only helps 10% max and only in multitasking and not in any single apps; 3) Its incredibly instable in a lot of apps (I haven't ran into one yet) and is often a negative benefit in single app mode; and on and on. If someone had did a decent review I could have known this stuff beofre I had tobuy one to find out myself....

I think it's all a conspiracy to keep AMD in the hunt. Well, it could be anyways... Either that or just bad information...

I updated with more heavy multitasking....

I have yet to get the system to be unreponsive or laggy with HT enabled and TMPGenc HT program enabled unless I tried to open some many apps in number I take up all 1024mb of ram....However I can get the not HT enabled (off in Bios) system come to a crawl and all about become near responsive....

 

[RaynorWolfcastle]

Very nice tests

 

[Acanthus]

I noticed an enormous increase when i moved from a 2.4B@2.9ghz to a 3.2HT on the exact same rig.

Duvie, disk is on it's way..
