does the regular 6800 use DDR or gDDR3?

on the nvidia 6 series overview pdf, they stated only the 6800U, 6800GT, and 6600GT use gDDR3, also on Newegg, 1/7 6800 cards say it uses gDDR3. Does this mean the regular 6800 only use DDR memory?

 

I haven't heared of a 6800 with gDDR3 before so I guess most use DDR. Mine uses DDR as well.

 

The normal 6800 with 128mb use DDR.

There are some weird editions with 256mb and DDR3 which allow to use higher bandwith and they really rock.

BTW, the 6800GS would be something similar to a 6800 with the power of DDR3.

 

yeah, I think it's the 256mb PCI-E 6800's that have gddr3.

 

Correct.

There are also a few AGP versions out there of the same card, hard to find though.

 

no, most 6800nu's, both agp and pci-e use gddr1, clocked at 700 and 600 MHz respectively.
There are some manufacturers that produce models with gddr3 however, the asus v9999GE is the most known example. The ones with gddr3 should be able to get significantly higher mem bandwith though, so if you are thinking of buying a 6800, one with gddr3 is definitly worth the money.

Look at my card for example, it the asus gamers edition, i have been able to fully unlock it, and oc'ed it beats a lot of gt's.

by the way, it looks like the agp 6800gs will be just like the asus ge, 12 pipes, 350MHz core, 1GHz gddr3. Its only unknown if it will be able to unlock.

 

6800GS isnt actually regular 6800. core is totally different..

Well.. not totally but its different size... u know. 0,11nm. normally 0,13

 

thats the pci-e version,it uses the same core as the pci-e 6800nu. The agp gs will feature nv40 core, 350core, 1000 memory:
6800gs agp
i cant find the link where it says that it will use nv40, but it was in the news a few weeks ago.

 

As indicated in a previous post, the 6800 GS is not the same core as the 6800 NU. While it shares a similar spec as the 6800 NU with 12 pipes and 5 vertex units, it is based on the newer 110 nm NV42 core. More specifically, the 6800 Go used in past generation high end gaming laptops. It also runs at 1.37 V on the core and uses GDDR3 memory. Most, if not all, will clock well past a 6800 NU to around 500 MHz. But there is also no chance at unlocking the extra quad that may have been successful on the 6800 NU cores. The one I tested did 520/1300 easily on the stock cooler which also sports a copper heatsink for the GPU. The XFX XXX version comes stock at 485/1100 for about $200. This item is designed to fill the gap between the 6800 GT and Ultra which are no longer produced since they are based on an old 130 nm fab process (like the 6800 NU).

 

Asus 6800 Gamer Edition comes with DDR3.

if you look at the table in the review here, you can see that both nu and gs use nv42. The gs does clock a lot higher though, due to being 110nm instead of 130.
if you dont believe the agp version will use the 'old' nv40 core: news article nforecers hq, news article guru3d
default clocks will be 350/1000, and xfx will have an oced version that does 400/1100: http://www.overclockers.co.uk/acatalog/6800_Series.html

 

Hilbert made a boo boo. The 130 nm core is the NV41. No 130 nm process fab cores are made any longer (NV 40, 41 or 45). The AGP version of the 6800 GS appears to be using the old AGP only chips (NV40). Since it is a limited release from one manufacturer, they can use the last of the 130 nm cores for these cards. The great thing is that all the NV 40 cores, including 6800 NU, GT and Ultra binned cores with probably find their way into these cards. So, you may get a gem. However, if they use the fixed core with the video decoder working (who uses it?), the NV 41 (which I suspect), they may not clock as high since they were made specifically for the 6800 vanilla at 350 MHz. Hope the rumors are rightand they use the NV40 cores or the AGP version may be a bit of a dog compared to the NV42 PCI-E version.

 

didnt know that, i was wrong on nv41-nv42

 

evga just released a 6800 with gddr3 ram.

i dont understand why they bother to give it ddr3, and clock it at 600Mhz.

 

You dont understand?
The normal 6800 cards are DDR clocked at 750 mhz.

Can you imagine the difference between 750 and 1200 mhz?

Or am I wrong and those new cards are just clocked at 300 mhz? 600 because DDR?

 

i know how big the difference in performance is between 1200 and 750, but i think you understood it wrong, they clock it at 600Mhz effective or 300Mhz actual, and that speed is easily accomplished with ddr1, and ddr1 is way cheaper than ddr3.
