Which CPU for encoding video

[Matrix]

Following on from a thread i made in the motherboard section i'm wondering what be a good choice of cpu for using to encode video.

I'm running a E6600 at the moment and was looking at something like a quadcore Q6600 but would there be something else i should be looking at if so what?


Still undecided if i will sell my E6600 and move on to another CPU and it would have to work with my Asus P5W DH Deluxe board.


And if i did sell my motherboard what should i be looking at to buy?

Thank you.

If you can stretch to something like a Q9400 tha might be better, the 45nm chips have SSE4 which gives a decent boost for encoding.

would also a big cache size help?

Im sorry I cant provide a link but im sure I read somewhere AMD Quads are better at encoding than intel cpus.

Not sure where you got that info from:

http://www.hardwarecanucks.com/foru...md-phenom-x4-9750-quad-core-cpu-review-9.html

Even a q6600 is 21% quicker than a Phenom 9750 and a q9450 is 45% quicker.

And another example here:

Reported to be up to 40% with appropriate software:

I'll have to look into selling my E6600 then and looking into buying one of these in the very near future.

Well 2nd hand q6600 can be had now for £80ish

There are the new Q8200 to consider as well.

With Intels next cpu just round the corner, once they come out they will be a lot of cheap, fast quads for sale.

So what would be best to go for then?
Q9400 , Q6600 , Q8200 ?


Thanks.

Q9400

Q9400

Do OcUK sell them as i can't see them they have :-

Intel Core 2 Quad Q9300 LGA775 'Yorkfield' 2.50GHz 6MB-cache (1333FSB) Processor - Retail

Intel Core 2 Quad Q9450 LGA775 'Yorkfield' 2.66GHz 12MB-cache (1333FSB) Processor - Retail


Thanks

They're only starting to appear, tho I'm not sure why OcUK don't have them in yet.

Ok thanks .

Is there a big ( noticeable difference) between a 6mb cache and a 12mb cache?

As the Intel Core 2 Quad Q9550 has 12mb cach and the 9400 has 8mb cache?

Thanks.

Wondering if anyone could answer ths for me please?


Thanks.

id go for a q6600 and clock it up to 3.6

I'm not really intrested in overclocking it just want to run it stock.

lol sorry.

The cache will make a nice difference but it's not as significant as you think. Also you can gain a lot of performance by setting the FSB to 400mhz which pretty much any modern board will do and the CPU will most likely do it without even touching voltages.

You can see results there...obviously lower is better, the ones in red are overclocked

 

[juno_first]

Its easy to overclock (you can even buy them from ocuk overclocked with a guide) a Q6600 95w easily hits 3.5+ & if you're transcoding you'd be mad not to consider overclocking.

Ahh, I remember the days using DOS to crunch+mux to divx3.11... taking 8 hours on a Barton was no fun lol, now the same job takes 30 mins

Plus some software is not happy with using 4 cores, SSE4 etc.
