Need more CPU Power what to go for ?

Randall8686 · 8 Sep 2013 at 22:30

Hi All

Well a new hobby of mine has meant i am now doing loads of rendering on sony vegas and well its taking quite a while on my Processor (see spec in sig) the 2500k is overclocked to 4.2ghz but during rendering its maxing it out 100% (as it should) but just taking 20 mins to render a 2 min long video @1080p

whats the best route for more horse power new cpu or change out the mobo too ?

opinions please im a bit rusty on current CPU's budget of about £200-300

You could up the clock another 200-300mhz if your cooling is good.

Another option would be to move to i7, a 2600k/2700k or equivalent ivybridge would give you some extra grunt if your software can utilise the extra threads.

I'd suggest you increase your overclock to speed things up but your sig says 4.6?

bicpug · 8 Sep 2013 at 22:37

Hyperthreading and ram would speed you up.

well on your budget the best you could do is to get an I7 3770k and 16gb of ram, but I'm not sure if the HT on the I7 would help that much on Vegas.. maybe 20% faster.

Yea i Lowered the Clock as i did not use the increase at the time i will load that profile again but it wont make a massive difference ?

Was hoping to get a 30-50% reduction in Rendering time. Done an hour long video the other day it took about 6 hours to render

Cooling is ok its a corsair single water rad nothing special but it stays around the mid 50's with only 1 core going to about 61c

Will ram help ? when looking at the useage (its rendering now its only using about 4gb) I have the GPU helping a little but it does not load it up much.

Depending on the software, an OC'd 8350 can give exceptionally good results in rendering.

Martini1991 · 8 Sep 2013 at 23:24

You're looking at a 3770K.
Or jump to a second hand 3930K set up.

Change your settings? I can do quick and dirty encodes of NCIS episodes in a few minutes.

Randall8686 · 9 Sep 2013 at 15:14

Unfortuantly cannot do quick and dirty (not on the video quality any way)

Will pushing another 3-400 MHZ hout of it make much difference on the rendering ? could always upgrade my cooler and bump up the volts.

to be honest its no longer used for gaming at all so could sell the 480 to fund even more CPU power.

wazza300 · 9 Sep 2013 at 15:19

should be able to do 4.5-4.6ghz

free upgrade,then maybe better cooler if it needs it or faster memory,then see if you need a multithreaded cpu

Randall8686 · 9 Sep 2013 at 15:39

will give it a go. i seem to remember i had to have the voltage a little higher than i should for 4.6

You ought to consider an overclocked 8320/50, at 4.7GHz it'll give the same performance as the 9590 here:

Rendering and encoding software varies, but this is not unusual.

thats a big jump over the 2500k is there much value in second hand 2500k's these days ?

~>Dg<~ · 9 Sep 2013 at 16:12

still shouldn't take 20 minutes with your spec

Martini1991 · 9 Sep 2013 at 16:19

That may not be even remotely relevant to the software he's using though.

People will be shifting 3930k's, I'd deffo jump on one for encoding.

wazza300 · 9 Sep 2013 at 16:20

have you ever compared with what your oc'd to now and a 4.5-4.6ghz render?

see how much faster it is

Like I said, the results are not unusual. AMD's 8 core processors are well known to be especially good for encoding and rendering.

This is the only recent benchmark I can find for Sony Vegas.

No as i would not image a huge ammount of difference is to be had but i will knock it back up to 4.6

That benchmark shows not a huge difference in performance to be honest. 6 hours of rendering does take its toll lol. The pc is still more than useable for web etc while doing it but it does max all 4 cores to 100% everything thats rendering is all on SSD's and the ram does not seem to get hammered im sure its all down to cpu speed 100% i cant actually be sure that Vegas uses hyperthreading but im guessing it must

wazza300 · 9 Sep 2013 at 16:36

it does,hyperthreading would quicken things considerably
