Video Encoding, Editing & FX : Opteron 165 vs Presler 920 ??

[ctbrown]

Hi, I'm new to this forum.

I will be upgrading soon, and, as the title imlpies, I'm trying to decide between the Opteron 165 or the Presler 920. I plan to overclock as much as I can safely using air cooling.

I don't game very much, but I do video encoding and editing and use video FX software. Some of the software that I typically use includes Adobe Premier, Adobe AfterEffects, TMPGEnc, DVDshrink, DIVXtoDVD and Virtual Dub. I also tend to have lots of apps and browser windows open all of the time.

So I was wondering if anyone has any 1st hand experience or point me to any relevant benchmarks. I would like to decide soon since the price of the Opteron will be increasing very soon.

Thanks

I'd go with the opteron. I have an X2 @2.618ghz, and a Presler 920. Haven't been able to get my 920 past 3.43ghz stable so far, and it is WAY behind the X2. Took 1 hour 30 minutes to encode LOTR: fellowship of the ring to DivX with my 920@3.43ghz, took 1 hour 10 minutes with my X2 @2.618ghz. The added cache of the opteron will make some differance as well, maybe reduce the time by another minute or 2.

EDIT: This was using AutoGK btw.

If I can't hit 4ghz with the Presler 920, I don't see any point in getting it. However, from what I have been able to gather, Operon165s are guaranteed to hit 2.6 ghz

I'd wager whatever your 920 overclocks to will just about match the Opty 165@stock for what you do.

some might not approve of their testing methods, some say their intel biased, but thats stilla X2 winning. now a opteron 165 will do 2ghz easy. it would be a very big shame on AMD if it didnt. the 920 has a little more cache then the 820 but that wont make up for that kind of performance.

now it seems per 200 mhz, the smithfields shave off ~20 seconds. (which is actually less the higher you get but lets take it for the sake of the arguement), so your presler needs to clock about 3.4 to keep up with a amd 4800+. the opteron will do those speeds. the opteron will get to 2.6 ghz, so, it shaves off about 20 seconds off too. meaning your presler should already be able to overclock to 3.6 for equal results. seeing the decline in those charts, make that 4 ghz. then it "matches" performance, so you'll want another 200mhz to be better. meaning you already need a 50% OC for a presler to be able to beat a opteron @ 2.6. and seeing as its higher grade sillicon, it'll most likely go beyond 2.6 with decent cooling.

now at that 4.2 ghz, it will give off enough heat to heat your room, and guzzles up so much juice that you might aswell gone with a more expensive AMD chip. clear choice really..

Well now up to 5 differant motherboards I've tried my 920 on. On 3 of them, 2 with the 945G chipset, 1 with the regular 945 chipset, it wouldn't go past 222mhz FSB. On my Asrock 774Dual-880pro, overclocking worked backwards, if I increased the FSB in the bios, it would actualy decrease it, and run the chip slower that it's rated speed. On my P5P800-SE, I've gotten it stable up to 3.36ghz, but not beyond that, so it seems the only ones getting presler to 4ghz+ are using the Asus P5WD2 Premium, which costs $200+.

EDIT: with a little help I got my P5LD2-VM past the 222mhz FSB limitation, by setting the PCIe to 110mhz.

Ran autoGK, sicne that was what was crashing before @3.43ghz.
My best time on the X2 before raid-0, was 1 hour 10 minutes, got 1 hour 7 minutes 43s with raid-0. My Presler now that it is at 3.64ghz on the stock heatsink, with a single 80GB sata drive, took 1 hour 7 minutes 59 seconds...not looking so bad after all although it does still run warmer than the X2, it still runs cooler overcloked than my 830 did at stock.

4ghz isn't that much of a stretch I don't believe. Last week I put together a new system with p5wd2-p and and a 920 cooled by big typhoon @ 4100mhz 1.35vcore

Not bad imo.

Check out the AutoGK thread now, me and techno have our results in there with our OC'd Preslers..and they have pulled ahead of the OC"d X2's.
