What is the speed ranking for these 3 cards?

[StrangerGuy]

Is it, from fastest to slowest:
1. X1800XT 512MB
2. GT120
3. 6800GS 256MB PCIe

 

[ViRGE]

X1800XT, the 6800GS, and finally the GT120

Isn't the GT120 almost like a 8600GT? 32 shaders, 128bit DDR2. I'm pretty sure it's quite a bit faster than a 6800GS which was kinda sucky when it showed up to begin with... It wasn't terribly bad, but it sure wasn't a speed demon either GT120 link

I'd say it's X1800XT > GT120 > 6800GS

Is it? I thought it was an 8 shader part.

Pretty much got it right.

I'd rank the GT120 last, based on mem bandwidth alone.
It would mostly matter what you are running to benchmark the cards, but the gt120 would be starting off at 1/2 the mem bandwidth compared to the 6800GS. That's too large of a handicap to overcome imo.

X1800XT 48GB/s
6800GS 32GB/s
GT120 16GB/s

well you would be wrong then because a gt120 would walk all over a 6800gs. except for 35% less memory bandwidth and slightly lower core clock, a gt120 is basically a 9500gt which is well over twice as fast as a 6800gs in modern games. a 6800gs couldnt even begin to play modern games at higher settings than a gt120 could.

It's like you took the words right out of my mouth. I read that one and thought "Well, that could have been a lot worse."

To keep in topic, I believe the GT120 just has too many SPs (32?) compared to the 6800gs, so the 6800 can tout its higher bandwidth all it wants, but too much raw SP power is on the side of the GT120 versus the 6800gs.

exactly right. the gt120 is basically a memory bandwidth crippled 9500gt. that reduced bandwidth still does not allow the 6800gs to come close to matching the gt120s performance in modern games though.

 

[Qbah]

The 6800GS is a 12PS/5VS card. How can one even compare it to a 32 shader card and think it might have a glimpse of a chance to get remotely close in performance to the DX10 card is beyond me... No amount of bandwidth can even begin to close the gap. Unless the GT120 would have a 64bit SDR memory interface...

I see you people are fast to disregard parts of my post:
"It would mostly matter what you are running to benchmark the cards"

I didn't make a blanket statement.

I'd take the mem bandwidth personally.

the comparison reminds me of the fx5200 vs. the ti4200

If you disagree show some benchmarks

you would take the memory bandwidth for what? its a FACT that a 9500gt is well over twice as fast as a 6800gs. a gt120 is a 9500gt with 10% less core speed and 35% less bandwidth. do you really think reducing the memory bandwidth by 35% is going to make the gt120 lose every bit of its performance and then some? its not going to happen and a 6800gs will not touch a gt120.

gpu clock mem bandwidth GP/s GT/s
gt 120 500 16GB/s 4.4 8.8
6800 gs 450 32GB/s 3.4 5.1

-11.1 +100% -29.4% -72.5

I pulled the GP and GT numbers from wiki, and checked against nvidia's

other notes: can't compare the different cores or their SPs directly. They are different designs:

gt 120 32:16:8 Unified Shaders (Vertex shader / Geometry shader / Pixel shader) : Texture mapping unit : Render Output unit
6800 gs 5:12:12:8 Vertex shader : Pixel shader : Texture mapping unit : Render Output unit

as the 6800 didn't have a unified shader model you aren't really comparing 32 SPs to 12 SPs

would be more like comparing 32 to 29 if you add up the dedicated vertex, geometry and pixel processors


again it really depends what you are using to benchmark the two (the op didn't specify)

ok so much for theories, lets talk REAL games. we all know a 7600gt is equal to or faster than a 6800gt which of course is faster than a 6800gs. now look how the 8600gt is almost TWICE as fast as the 7600gt on average. well so thats easy to deduce that an 8600gt would be well over twice as fast as the 6800gs. heck the 8600gt is even beating the 7900gs. there is a 6800 128mb getting killed on there but I have no idea if it is a gs or not. I didnt include it because it is only a 128mb model anyway.

an 8600gt is basically identical to a gt120 as for as sp, tmu, and rop. now a gt120 has faster clocked shaders than a 8600gt but does have 35% lower memory bandwidth and 10% slower core clock. there is NO WAY that the 35% deficient in memory bandwidth would bring it down to 6800gs levels. to get that low it would have to lose way over 100% of its performance which is impossible.

btw please dont look at release reviews of the 8600gt. the initial drivers were garbage and caused the 8600gt to be not much faster than a 7600gt on release. the next set of drivers fixed that and gave the 8600gt a massive increase in performance. I know because I owned one plus you can see in those four benchmarks that overall its basically twice as fast as the 7600gt once the drivers were updated. I just figured that needed to be said so people dont pull up those initial 8600gt reviews.

yep. for modern games all those cards are quite poor. heck a 6800gs doesnt even meet the minimum requirements to play some newer games.

I don't think we are going to find a clean comparison of the two by any means. I'll just agree to be unpersuaded .... I liked my 6800XT

My only thinking is that some older games or memory badwidth limited games would favor the 6800GS

Right here and now i'd have to agree with you that the GT 120 would be a better buy for several reasons: Power usage, unified shader model, later dx/OpenGL compatibility, and opencl/cuda support. But asking if the card is faster is open to interpretation.

 

[Arkaign]

The X1800XT can still play modern games fairly respectably, albeit maybe with lower AA or no AA at higher details on 1680/1920 settings.

The GT120 is almost useless outside of HTPC duties, just like the 9500/9400/8600/8500/etc.

The 6800 was a great card in it's day, but that day was a looooong time ago. When did the 6000 series come out, like 2004 or so? That's gonna be six years ago in a few months.

X1800xt can barely play Bioshock @ 1650x1050.

Recommended Requirements
CPU – Intel Core 2 Duo processor
System RAM – 2GB
Video card – DX9 – Direct X 9.0c compliant video card with 512MB RAM (NVIDIA GeForce 7900 GT or better) / DX10 – NVIDIA GeForce 8600 or better
Sound Card – Sound Blaster X-Fi series (Optimized for use with Creative Labs EAX ADVANCED HD 4.0 or EAX ADVANCED HD 5.0 compatible sound cards)

That was 2007.

 

[Qbah]

There you go:

Tom's 8600GT vs 6800GT (GS is even slower...).

8600GT kills the 6800GT. It would slaughter the GS.


EDIT: And so that we have the whole picture... X1800XT vs 8600GT vs 6800GT. Note it's the 6800GT here (=faster) and not the GS.

Bioshock is pretty crazy with recommendations though. I saw Dragon Age : Origins running just fine on an X1900GTO a few days ago. Looked great at 1680x1050, and that's a brand-new game.
