Will getting new PCs help...?
show user profile  ssava
I currently have two Gateway pcs with Intel Core 2 Quad CPU Q9300 @ 2.5GHZ and 4 gigs with Vista 64

I also have a Dell XPS with Intel Core i7 CPU 920 @ 2.67 Ghz and 12 gigs of ram with Vista 64

These machines are 2 years old and my renders seem to be taking FOREVER.

These cost me $1,200 each (with monitors) at Costco 2 years ago.

Would similar priced machines run much faster if I purchased them?

I'm not one to build my own machine. Just not my area of expertise.
But I'd like to know if the CPUs have increased much over the last 2 years.

Anyone know? Scott Christian Sava

Im no expert but they sound quite good to me.

What sort of scenes are you rendering? it might be the user rather than the tools.

The scenes are big. Ocean, Pirate ship, lots of reflections, etc.
Currently about 20 hours to render.

I remember when I got the current computers...the scenes rendered in 1/8th of the time than the dual Xeon processors I was using before them.

The improvement was impressive. I thought I'd see if technology made another leap like that in the last 2 years. Scott Christian Sava

good thing rendering speed scales quite linearly with with each element in the ipc*core count*frequency equation so its easy to predict.

lets take your current pcs for example and say the c2q gets 1 point for ipc and the gulftown 1,06

we get the following scores -
gateway's 1*4*2.5=10 units of fantastically awesome render toughness (from here on referred to as FART)
dell 1.06*4*2.67=11,3 fart's
so assuming you use all of them for render at the same time they come to 31,3 FART's

to compare some other system you need the IPC value of other common architectures so taking the wolfdale as baseline of 1
sandy bridge - 1,22
gulftown - 1,06
phenom 2 - 0,95

considering that we get that a 2600 (stock settings) system would deliver
1,22*3,4*4=16,6 FARTs
overclocked (common OC)
1,22*4,5*4=22 FARTs

and amd counterpart t1100 @ stock
0,95*3,5*6=20 FARTs
overclocked (common OC)
0,95*4,1*6=23,3 FARTs

or lets go nuts and get a top of the line dual cpu 1366 system
1.06*3,6*12=45,8 FARTs
overclocked
1.06*4,3*12=54,7 FARTs

or if you got couple hundred thousand to spend a 1567 system would be cool
1,06*2,4*80=203,5 FARTs

for clarification 2 FARTs renders twice as fast as 1 FART and it is possible to buy a pc that will cut your render times tenfold if you sell your soul, you decide if its worth it.

wtf does ipc mean ?

current best processor is a xeon e7 but they're a bit pricey.

http://www.tomshardware.com/news/xeon-intel-sandy-bridge-e7,12526.html


the other solution is a GPU based raytracer & a high end graphics card.

geforce 590 or radeon 6990.

no direct experience so will leave to others to advise if this would be suitable.

instructions per cycle, to measure mhz efficiency between different architectures

and if by a bit pricey you mean 4 thousand dollars each then yea :p

EDIT: also for reference if you assemble your own pc and dont get ripped off you can get 2 2600 or 1100t systems for 1200$ easy

The new Hex-core chip beats all other consumer Intel chips, I've read.

hmmm. not all instructions execute in one cycle, then you have branch prediciton, caching, etc. on top of that. that's why you really need real world benchmarks for accurate analysis, but better than nothing as a starting point I suppose.

yeah - they're expensive. just sayin' they're out there. not suggesting they're economical.

bolts was on the blag for 4 on a board from intel. no idea if he got anywhere with it.

The cheapest hex-core is about £490.
The ones Bolte was trying to blag are the 10 core ones, not sold to consumers!

...Embree seems dead. The developers don't answer emails, and the forum is filling with spam advertising. Shame.

doubt it's dead. they've done what they needed to - verify they have an acceptable rendercore.

the next stage (if they're on the ball) is to build it in hardware. will take a couple of years.

i didnt mean the actual IPC value (since i pulled the baseline out of my ars :p) but more of an overall sum-up value

Thank you. But you lost me at FARTS.
:)

I just looked at a PC on the dell sight that has these specs...
Quad Core Xeon E3-1225, 3.10 GHz, 6M L3, 2GT, Turbo, Dell Precision T1600
8GB, DDR3, Non-ECC SDRAM Memory, 1333MHz, 2x4GB, FPWS T1500
1GB nVIDIA Quadro 600,Dual Monitor,1DP and 1DVI,Dell Precision T1600
2TB SATA 3.0Gb/s, 7200RPM Hard Drive with 64MB DataBurst Cache,Dell Precision T1600
Running Windows 7

Compared to what I have now...could you tell me (guessing) what the improvements would be?

That's a pretty quick chip. You'd see a decent boost with that box. I would suggest upgrading to 16GB, as memory is really cheap at the moment, and it will really help Max breathe.

Why a Quadro 600 instead of a 590 ?
