Need more CPU Power what to go for ?

[Randall8686]

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

 

[Randall8686]

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

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

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.

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.

 

[Randall8686]

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.

 

[Randall8686]

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

 

[Randall8686]

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 ?

 

[Randall8686]

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

see how much faster it is

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

 

[Randall8686]

it does,hyperthreading would quicken things considerably

cool ! so confused with all the CPU choices now lol. i assume the 6 core i7 is going to be a mobo change

 

[Randall8686]

might give a 2700k a go. if i decide to really go to town and blow a bit more cash on this what would be an ideal board / cpu to get the fastest rendering.

 

[Randall8686]

ahhhhhh lol. i can up the budget if i can get a 50% increase

 

[Randall8686]

Im using Vegas Pro 12

The graphics card is a 480 (as in sig) will have to see if i can find this info out

 

[Randall8686]

Infact i already have OpenCL turned on so i think its already using the GPU to render (helps CPU)

 

[Randall8686]

Its a Legit copy, Purchased through my company. So that should not be a problem

 

[Randall8686]

what vegas settings you using as said a 2 minute render should not still take 20 minutes.

is your copy legit or a cracked version as this could be your problem

The actual output setting i use is internet 1080p @ 30fps all the footage i shoot is at 1080p 60fps

 

[Randall8686]

its about 15-20% slower with the GPU disabled
