E8400 vs Q9300..?

[topcat888]

Hi

Can anyone advise me, I do quite a lot of video encoding and at present have an E8400 which I am happy with, but I have seen some Q9300 chips at reasonable prices and wondered if that chip would be faster at encoding than the E8400..? (because it's a quad..?)

Thanks

The quad core will mince the 8400 at encoding

The quad core will mince the 8400 at encoding

As long as the software is multi-threaded to use the extra cores.

Well yeah, that stands to reason - but most encoding software is capable of utilizing a quad core cpu isn't it - even some games can use four cores, so I'm sure newer encoding stuff can

topcat, what software are you using for encoding? Find out if it CAN use a quad core, if it can you're on a winner

No not really. I find it very hard to find video apps that use all my 4 cores maxed. Most of the time the usage is 50% when encoding, granted it is using 4 cores but not to any real use, probs about the same as 2 cores maxed out.

The only program to 100% all 4 cores is handbrake, thats what I have found so far anyway. If anyone has software that maxs all 4 cores I would be glad to hear about them

Winavi can do a dvd in about 9 mins. Devede in about 25 mins, so times are good, but I wonder if all 4 cores were maxed those times would drop even more. Those are both at 50% usage

Cheers

Yeah Vegas Pro doesn't even use all cores, it's often faster to just output as RGB and then encode with Handbrake.

Other than that, only a few programs I've written myself will use all 8 CPU cores on my machine (or if I'm running 8 separate calculations simultaneously).

Thanks guys...

I have contacted the dev of the software and he says it will def use all four cores, so I'll give the q9300 a go...

I'm assuming that four cores more than makes up for a lower clock speed..??

This is not at all scientific and given as a very rough illustration only:

E8400 2 x 3.0GHz = 6GHz of "processing power"

Q9300 4 x 2.5GHz = 10GHz of "processing power"

You can always try overclocking the Q9300 as well.

+1 the Q9300 should clock up to 3.5 easily maybe more...

So, using Surveyor's method, that's:
4 x 3.5GHz = 14GHz of "processing power"

Sounds good to me

I hated putting it like that but it seemed the best illustration.

I sound like one of those people on an auction site who sell a quad core processor as if it was 10GHz

I sell one Q9400 which is even better, and unpredictable cool in idle, look for Q9400 on most known auction website, auction ends tomorrow (Sunday)
