How does OC'd 8400M GT compare to 8600M GT?

Hey guys, im a little curious how my 8400M GT OC'd to 600/731 would compare to a 8600M GT DDR2 or DDR3.

My 3Dmark06 score is: 3521


Is the performance almost...identical for the non-oc version of 8600M GT DDR3? or DDR2 version. THX!

 

What resolution are you running on? 1280 x 800? Or lower?

 

1280x800 sir

 

I have a 3611 3dMark06 score with my stock 8600 GT DDR2 and 174.74 drivers.

 

The performance seems to be identical to the other 1280 x 800 scores posted for stock clock 8600M GTs. Most of the scores seem to range from 3400s to 3700 or so.

 

Hm...so how is the performance to the 8600M GT DDR3 version?

 

You won't ever hit the 8600m GT GDDR3 speeds. The 8400m GT lacks the necessary pipelines, plus you're running 3DMark at the wrong resolution. You need to get at least 3700-4000 at 1280x1024 to even be close.

 

Yeah...an OCed 8400GT might be on par with the 8600GT Stock DDR2, but 8600 DDR3 is definitely faster, and a lot more overclockable....well....check out my sig for 3DM06 Rating running under 1440x900

PS. Don't take 3DM scores for everything...game performance vary depending on your hardware configuration independent of the 3DM score.

 

Im a little confused as to why you have a mad face beside a T9300 CPU shawnhao

Anyways yea your scores are about even with an 8600GT at 500/400

 

But I believe the gaming performances will be less, especially in shader intensive games since it only has half of the shaders.

A 8400M GT at your clocks looks like a 8600M GS GDDR3,

 

Yes, having owned both video cards, I can safely say an overclocked 8400m GT wouldn't come near an 8600m GT DDR3.

Probably fairly close to an 8600m GT DDR2 though.

 

Hehe...I was aiming for the 9500, but clicked on the wrong buttom at the dell config screen and didn't realize the problem until the lappy came to my door with the invoice (didn't bother to double check my order confirmation.... )...so yeah...I ended up with a 9300....pretty pissed at myself....but since I got a LG panel, everything seems perfect, so I didn't want to try my luck with a reorder and just stayed with the 9300....

 

GeForce 8400M GT
Stream Processors 16
Core Clock (MHz) 450
Shader Clock (MHz) 900
Memory Clock (MHz) 600
Maximum Memory 512MB
Memory Interface 128-bit
Memory Bandwidth (GB/sec) 19.2
Texture Fill Rate (billion/sec) 3.6

GeForce 8600M GS
Stream Processors 16
Core Clock (MHz) 600
Shader Clock (MHz) 1200
Memory Clock (MHz) 700
Maximum Memory 512MB
Memory Interface 128-bit

So if you oc your 8400m gt enough you can have an 8600m gs

The 8600m gt is in a whole other league..

 

See sig for specs and 3DMark06 score (using 174.31 drivers). I just discovered that I could change my power management options to High Performance which apparently brings the video card to full clock speed. This in turn should improve the 3Dmark score. I will rerun tonight and update if there is a change.

 

With ATI TOOL ive managed to find the core clock limit of my GPU! And believe me...it was far beyond what i expected..

My computer flickered and crashed when the core clock got to around 780 (almost 800)

LOL it wasnt pretty when it crashed though. I was scared to death. Luckily my computer shut down before damage was caused.

 

Well first off that's the tested "limit" for your card...

Second, if your computer has to shut itself down for heat/glitch reasons, that's not good.

 

Different for everyone.

 

I think he was just messing around to see how high it would accept the clocks. I could be wrong...

 

That's a great idea. Let's see just how hard we can push a part that, if damaged, will basically brick the laptop.

 

I think the drivers will crash before the card gets damaged though.

Still, I can use my C90S with the 8600 at 110C for an hour and no problem. Instant crash at 115 though. But I force cooling with folding@home and keep it at 96

 

mine is running that hot right now also, but thats most liekly because it decided to not like powermizer, and not clock down

 

After I had ATITool's auto-tune FUBAR an All-in-Wonder 9800 Pro I had a long time ago, I've been fairly conservative in overclocking video cards.

It was working fine, fantastically, then one auto-tune later and even at stock speeds I'm getting memory artifacts (white dots) on everything, and these white dots did not go away. I had to RMA the card.

 

It's pretty messed up, my Geforce 9500M GS with stock clocks at 475/950/400 overclocked to 522/1045/440 reaches 77 or 87C while gaming. I'd expected my notebook to run cooler than this. It doesn't make sense as I'm not overclocking by too much.

 

That is huge freakin OC there.
My setup can get nowhere near 6100 without artefacts . And my card is 20-30% better than yours...7000K, that`s the stock score of the Gateway FX with the 1.66 C2D cpu and 8800M GTS..
Nice nice...

On topic, the 8400M GT can reach a 8600M GS easily,but that`s about it.

 

Calm down guys lol...It was tested with ATI TOOL ...i didnt ACCUALLY push the clocks that high ( i would have been nuts). My laptop is fine. No glitches or whatever...
