Oops - I posted this in the FAQ - naughty boy!!

I'm looking at a Dell XPS 435. It offers the Nvidia GT 220, here.

In the "Specifications" tab it says it's CUDA-capable, but I don't see it in the list of cards in the FAQ.

Will it run GPUGRID?

Thanks, Tom

It's got 48 shaders at 1.3 GHz, so it looks similar to the 9600GSO 512 MB. It will be relatively slow, but should finish a WU in under 2 days. Which is sufficient to run GPU-Grid, even if you don't crunch 24/7.

but the card's architecture is newer...

A Dell XPS 435 ?!?

Why?

Its not for the graphic card, thats for sure!

Believe me when i say "i don't like dell anymore"

5 computers from dell and i can't do much to them... locked bios, etc....

i'm not buying dell unless it's a laptop and cheap.

Good point. I assumed they wouldn't pass the new GT200 architecture down into the performance-doesn't-matter-anyway range if they did not even bother to do it in the mid range. And that if they didn't tell us a super cool new feature is included it probably isn't.

Anyone feeling bored enough to ask them whether "GT220" is CUDA hardware capability 1.1 or 1.3 or else?

A Dell XPS 435 ?!?

Why?

My principal requirements on any PC purchase are:

1. A decent warrantee, with on-site service.
2. Everything in English.

Since I live in France, 2. is a challenge. The only source I've found is Dell, who will supply an all-English PC and three years on-site service, extendable by another two years.

XPS 435? i7 processor at a price that's less than half their high-end gaming machines.

As the charming meerkat says; "Simples"!

FWIW, the Dell XPS 435 arrived four days ago. My first action was to swap its GT 220 with the 9600 GSO from my old Dell 9100 Pentium D 3.20.

After a few hiccoughs I've done two WUs on the GT 220. I missed the bonus on one. Seems they're taking about 26 hours to complete vs. 18 hours on the 9600 GSO.

It's not fast, but the GT 220 is doing the business!

what does boinc say for the 220?

how many gflops, and btw, how many cores does the card have?

it may just be me, but i have a feeling that when i buy dell, i get bought cheap.

what does boinc say for the 220?

The last time I looked it wasn't listed.

Don't understand the gflops question, but the Nvidia System Monitor shows:

* GPU Usage 97%
* GPU Processor 1336 MHzZ
* GPU Memory 789 MHz
* GPU Graphics 618

I tried upping these values by 5% but the BOINC client died...

The GT 220 has 48 shaders ("cores"?).

it may just be me, but i have a feeling that when i buy dell, i get bought cheap.

The crazy thing is that Dell Europe only offers the GT 220. Dell U.S. let you buy the GTX 260 with the XPS 435.

what did boinc, message log say when you booted with the 220. it should say something like this.

"8/28/2009 12:50:27 PM NVIDIA GPU 0: GeForce GTX 260 (driver version 19062, CUDA version 2030, compute capability 1.3, 896MB, est. 104GFLOPS)

Ummmmmmmmmm. Ummmmmmmmmmmmm.

Help me out here. Where do I find this info??

Tom

Boinc Manager, Advance view, Messages tab. it's at the top of the messages after cpu and some other stuff.

How about:

02/09/2009 19:28:49 CUDA device: GeForce GT 220 (driver version 19062, compute capability 1.2, 1024MB, est. 23GFLOPS)

Tom

thanks, we were wondering what compute compatibility of that card was, 1.2 not bad, it's a step up from 1.1 of the 8, 9 series.

Anyone feeling bored enough to ask them whether "GT220" is CUDA hardware capability 1.1 or 1.3 or else?

It's 1.2.

Tom

The GT220 looks really nice for a lew end card!

His 9600 GSO has 96 shaders * 1.59 GHz -> 458 GFlops (*)
The GT220 has 48 shaders * 1.34 GHz -> 193 GFlops (*)

For a WU with 3997 credits the 9600 needed 63500s, whereas the 220 needed 89700s. That's 68% more performance per maximum GFlop for the GT220 compared to the 9600GSO. That's way higher than the 40% which I found when comparing GT200 (now talking about a chip, not a card.. gotta love those names) and G92.

-> compute capability 1.2 seems to include whatever made GT200 faster than G9x
-> 9600GSO may be limited by memory bandwidth

- 9600GSO: 11.9 GFlop/GB**
- GT220: 7.6 GFlop/GB**
- GTX260 Core 216: 7.2 GFlop/GB**

MrS

(*) maximum GFlops, not measured by BOINC
(**) lower is better
