Xeon 5420 vs core i7 920/940

Last response: in CPUs
Share

Hi,

I am updating my intel q6600 system and not sure whether to go for a dual quad-core Xeon system or a single core i7. I need faster render times and something that can keep up with my editing speed w/o compensating system stability!

My editing is generally a few layers of XDCAM/standard DV video, and consists of simple fades, cuts, speed/colour corrections, 2d text overlays and noise reduction/gain/eq/limiter audio enhancements.

Specs:

1x core i7 (- 920 (2.66ghz) / 940 (2.93ghz)) on an asus p6t x58 mb, 9600gt 1gb, 1600mhz 9-9-9-24 6g ram, velociraptor boot drive, 2x (2x1tb raid0), vista64, ~700w psu, thermaltake armor case, etc....

OR

2x xeon 5420 (2.5ghz) on intel 5000p mb, ECC 667mhz 8g, (rest as per above.)

Xeons are the more expensive option, but will they be quicker and/or more stable than a stock i7 -920 or 940 for CS4 editing?

The CUDA is definitely amazing, but looking at Australian prices the CUDA sells @ $3.5k!, whilst a complete dual 2.5ghz xeon sytem with 8g ram is around 4k and i7 -920/940 around 3-3.5k. Not sure I can justify buying the gc over a complete new system in light of these prices...

I have a dual xeon system. It has the asus DSEB-DG board (1600fsb) , modded dual xeon 5410 running at 2.8 with tape mod, 16 GB of fbdimm.
These days 4x4gb sticks are about 450 on fleabay.

this board also has crossfire compatible dual 16x PCIE slots
very responsive, even with multiple VMs running.
fast for multithreaded video encoding

guys what do you think about following configuration, will that be enough to render HD 3D Videos, also for After effects, VFX, Full HD videos? or please suggest something which will also do the same job in lower configuration.

Two Intel Xeon 5420 2.50GHz
NVIDIA Quadro FX 3700
3 TB hard disk
Intel Motherboard SC5275 or 5520
8GB or 16 GB RAM

I just build a new system for myself using a Xeon W3520 specifically so that I could use ECC memory. The W3520 is the workstation variant of the Core i7 920 and is essentially identical except that it supports ECC memory. Total price of the system, including 12GB of Kingston ValueRAM DDR3 1333 ECC memory and an Asus P6T6 WS Revolution motherboard was only about 10% more than an equivalent non-ECC Core i7 version using a P6T Deluxe V2 motherboard.

I consider that a small price to pay to plug the only gap in most systems in which error checking is not done.

I have read that the Xeon W3520 only supports up to DDR3-1066 ECC memory. How did you get the DDR3-1333 ECC memory to work? Did you have to overclock it?

I have 2 5420's that i'm about to build a system w\ as soon as i find the time... Got the cpu's for $180 on ebay for the pair ^^ thought it was a steal since they're 3.4ghz... the e8600 is around $150 and it's 3.2.

Xeon 5400 series is Intel Core architecture. I would go with Nehalem Xeons (3500 and 5500) series as sminlal hints at ^^^.

As for those suggesting CUDA, yes it's supported by CS4 but will only get you so far (since only for some functionality GPGPU is used). You still want powerful CPUs.

Idk about the exact stuff you're gonna be doing OP but I imagine for your apps even the memory bandwidth you have on single or dual socket Xeon with DDR3 1066 is good enough, given Nehalem uses triple channel.

HDVR® runs around 1.176 times faster on "2x xeon 5420 (2.5ghz)" then "1x core i7 (- 920 (2.66ghz)"
HDVR® runs around 1.8 times faster on dual E5540 then on dual e5440
