Anyone know of any 1 to 1 comparisons of 6800 to Go version?

I haven't seen any comparisons yet, but I have noticed that the 6800Go performs very differently to the 6800 desktop chipset in Half Life 2 - most of the time I'm getting 50-100fps but when in water areas where reflections exist it drops down to about 36fps (and the reflections sometimes drop in and out). If I'm close to an exploding barrel I get something like 10-20fps but worst of all is in the canals when a chopper is hovering overhead - if I look at the water where the spray from the chopper rotors is rising up off of it I get 6-12fps. These phenomenon cause my 6800Go to bench about 36fps on average in the canals where a desktop 6800 would bench maybe 80fps. I suspect it may have something to do with the 6800Go having 5 vertex shaders instead of 6 - but I'm not sure.

could be a driver issue.

Can you post a pic of what it looks like on your 9860? I heard someone else said the ATI in general renders water graphics better.. Im curious myself.. Actually I have the desktop 6800 128 12 pipeline.. its probably going to be a closer comparison.. then the 16 pipe version..

That water looks awesome in the picture.

This compares it to the 6600GT and it runs comparable to a 6800 so it might be helpful.

The standard desktop 6800 card has only 12 pipelines the same as the 6800Go, the 6800 GT and Ultra desktop models are the ones with 16 pipelines (and higher clock speeds). After further investigation I've also noted that just like the 6800Go the desktop 6800 has only 5 vertex shaders instead of the 6 in the GT and Ultra models - so I really don't know why there's such a considerable difference between these cards.

See here for a comparison of desktop 6800 variants...

I run my 6800Go at 346/686MHz (GPU/Memory) which is comparable to the stock speed of a desktop 6800 (325/700) - consequently my 6800Go achieves similar 3DMark 03 scores but in actual gaming benchmarks it scores much less in certain scenes/circumstances. I'm even running the latest desktop drivers - Forceware v 70.90 (unlocked for the 6800Go), but still there's definitely a noticeable difference in some situations - but only some, it's as though certain effects/functions are crippled on the 6800Go for no obvious reason.

I just bought a copy of hl2 for my dad for xmas. I'd throw it on my d470k (4750) to get benchmarks and screenshots on the mobility 9700 but I don't wanna give him a used game. My brother apparently is supposed to get 2 copies as he bought 2 9800xt's last year with the hl2 coupon so I'll try to bug him for his second copy.. he owes me anyways.

Quote: "As of December 13, this is the newest nVidia driver on the block. And yes, it does contain the new LOD Clamp that solves the texture shimmering problem that many people experience. Users with high-end cards are reporting faster benchmarks, both game and 3DMark. Unfortunately, that doesn't hold true for my slower FX Go5200. Here's why:

The latest nVidia cards rely on large amounts of fast RAM for texture handling and the 7x.xx series is optimized to take advantage of it. Although FX and earlier cards do work with the new memory management scheme, they can't take advantage of it the way the new cards do. Thus we're seeing faster benchmarks with newer cards, while older cards produce numbers slightly slower than before.

The effect is easily visible when launching "The Sims 2," where opening a new neighborhood requires an enormous amount of texture swapping while zooming down into, and around, the town. With the 67.03 driver this zooming is quite smooth on my laptop. The framerate isn't anything to celebrate, but it's visually consistent and smooth. Using 71.20, this same zooming is extremely jerky, with many halts and pauses while textures are swapped in and out of main system RAM. The overall framerate isn't much different, but the visual difference is striking and disappointing.

Thanks Krieger! I'll try it out and see if it makes any difference.

Let us know..i'd test it but my baby is on its way for a face lift

Hi there guys.
I have been playing HL2 straight for 15 hrs on max resolution for my 9860 screen with 4x AA and it had no stuttering or slowdowns that I could mention.
The Nvidia drivers I am running is the latest version downloadable from Sagers website.

My system specs are:
3.4 Processor
1 Gig Mem
60 gig 7200 RPM

One funny thing though. When I install Rivatuner, is states my 6800 Go as being 128 bit???
As far as I know the 6800 GO has 256Bit Memory interface. I must mention however that Rivatuner does mention not being compatible with the 6800 GO's drivers or design so it might be listing it incorrectly.
Will any one else please confirm this for me

Let us know what you find.
Andtreperhill, also try using Rivatuner latest version and see what it says for your memory interface.

HI again.
Just to show you what I mean here is a copy of the Rivatuner Diagnostics report:

$ffffffffff NVIDIA specific display adapter information
$ffffffffff ---------------------------------------------------
$0100000000 Graphics core : NV41 revision A2 (12x1,5vp)

$0100000007 Reference clock : 27.000MHz


It shows that Memory Interface as 128

on toms hardware is not a direct comparison of the 6800 and 6800go but at least to independent reviews. maybe that will help.

I tried the latest Forceware NVidia driver (v 71.20) briefly last night but switched back to v 70.90 shortly after I noticed all bar the most basic resolutions disappear (it got rid of all bar 800x600, 1024x768, 1280x800(I think), 1280x1024, 1490x900 and 1680x1050, and all the 4:3 aspect resolutions would only display in a cropped mode rather than stretched - YUK!!). I'll try and find a way to get the other resolutions working and re-enable stretching of 4:3 aspect modes before I re-install, I have to admit I don't expect there to be a huge improvement as I'm already running v 70.90 Forceware which exhibits the problems I mentioned earlier - after further investigation by the way, I'm not so sure anymore that there IS a huge difference in performance between the 6800 desktop and 6800Go versions. In most Half Life 2 reviews it's the high end Ultra and GT cards that get the attention, there are a few X800 Mobility vs. 6800Go reviews that also compare the 6800 desktop - but in each of these the 6800Go is only running at stock speeds which is a significant underclock of it's potential and notably slower than a desktop 6800 (they're also using older drivers). It's also significant I think that the slowdown I've noticed is only under the most specific of circumstances in HL2, only with exploding barrels when you're very close to them, with SOME reflections (looking through bars for example), with the spray from helicoptor rotors (looking at the canals without the spray - the speed is fine), and passing by SOME gas streams. There seems to be just a few specific effects that the 6800Go can't handle and I suspect that the 6800 desktop may struggle with these too - maybe it IS just the 12 pipelines that cause this???

Has anyone checked the 128 Bit memory interface that Rivatuner reports?

I posted my reults a couple of posts up.

I installed and am using the new forceware 71.20 drivers. I have had no problems and my 3dmark05 score has increased by about 7%. All other benchmarks did not change. I have noticed increased performance in farcry (runs great with SM 3 enabled). Try installing it using the performance config on that website - its been working great for me.

I have the desktop 6800 128mb my desktop is a p4 2.6 1 gig ram pc2700 7200 rpm hard drive. My 6800 is the BFG 6800 OC (over clocked for those that dont know) In 3dmark03 it scores just under 9k or about 8900.. my 6800go also over clocked scores just a little over 9k..

Are your 4:3 aspect resolutions running cropped or stretched? Do you still have resolutions like 1600x1000 or just the basic ones?

Yeah it appears i have all the resolutions including 1600x1000. If it makes any difference, i downloaded the new driver not from the laptopvideo2go but from this website and used the config file from laptopvideo2go. I'm not sure what my 4:3 resolutions are doing - i don't use them. But i tried one and they seem fine.

andrepeterhill i doubt the new drivers will make much diffference for you because your already using the 7x.xx set. I was using the one off the sager website in the 6x.xx range.
