450MHz 500MHz 600MHz
DDR DDR 3 DDR 3
128 MB 256 ~ 512 MB 256 ~ 512 MB
128-bit 256-bit 256-bit
800 MHz 1000 MHz 1200 MHz
8 12 16

325/620 for the 9700 pro vs. 450/800 for the x800se but the 9700 pro will have more than 50% higher ram bandwith but the x800se 38% higher core clocks. Hmm they might actually be close in performance, maybe just a hair behind the 9700 pro, but dude for $300 thats insane. 9800 pros would go up from $210 to $300 if this is the case since why buy the slower x800se? and alot of people cant afford a $400+ card either.

Im sure that the x800se will have a 256bit memory bus or it will be priced under $200.

I sure hope its 256 bit or theres a 256 bit verson in addition to teh 128 bits. $300 for a 128 bit is crazy, no sane person would buy it over the 9800 pro or the $400 x800 with 12 pipes, twice the ram bandwith

With the core clock that high, and the fact that is has more vertex shaders (i'm guessing) i doubt the memory will slow it behind a 9700pro.. but still, for $300, i doubt it will be a better deal than a 9800pro if the memory is only 128-bit.

As for the other specs O_O!

600MHz core, 1200MHz memory 16x1 for the X800XT!! if someone posted those specs here 4 months ago they would have been laughed off the forum. I just hope we have a good reason for not doing the same today.. R423 looks like exactly what i'm after :D

My try on the new cards:

X800 SE: 160 Mio. Trans.; Core: 450MHz; Mem.: 400MHz DDR; 128 Bit Mem. Interface; 8 Pipes; AGP8x

X800 Pro: 170 Mio. Trans.; Core: 500MHz; Mem.: 500MHz GDDR3; 256 Bit Mem. Interface; 12 Pipes; AGP8x

X800 XT: 180 Mio. Trans; Core: 600MHz; Mem.: 600 MHz GDDR3; 256 Bit Mem. Interface; 16 Pipes; AGP8x

X880 XT: 180 Mio. Trans; Core: 600MHz; Mem.: 600 MHz GDDR3; 256 Bit Mem. Interface; 16 Pipes; PCI-X

I can see 9800 pros going wayyyyyyyy up to $300 in price since they will own the x800se. why pay when you can get the faster 9800 pro? and not everyone can afford a $500+ card either. People will be mad they didnt get the 9800 pro when it was $210 but they are tired of their radeon8500 or fx5600 not cutting it in doom3 and HL2 so they take the $300 plunge for teh 9800 pro!!!!!!!

The X800XT sounds almost to good to be true :drooling:

If indeed the XT version does carry a 600mhz core clock then that is impressive for a 16 pipe part.

I guess Low-k is really helping out, otherwise maybe ATI's choice to not go with Pixel shader 3 (if true as well) and save transistors will have helped in transistor budget and heat issues.

Now if we can just get both NV and ATI to count their Trannies in the same way :angel2:

Thats what i think also, less features and smaller die size will indeed help in a higher clock speed.

Since the X800XT/X880XT are debuting a month later...maybe change those memory clocks to 800MHz (1600MHz). 600/600 is unbalanced and results in a bandwidth starved card. Especially with 16 working pipes.

thatll crush the nv40 sooooo bad, but I am worried about the x800se. Itll be half the performance of the x800 if it has only 128 bit ram. This will cause the faster 9800 pro to shoot in price

If r420XT is 16 pipelines and 600Mhz then they will have to be efficient on the pipelines or else the pixel fill rate will not be getting near maximum theoretical. However Ati have always been pretty efficient.

That makes no sense, could be cuz I've been awake for longer than is healthy, but oh well.

The way things usually work, a different chip uses a different code name. And the only codenames we know about are R420 and R423. ATI doesn't seem to be in the habit of using the same codename for multiple chips that are very similar, let alone as significant difference as 10 million transistors. They went from R350 to R360 and very few changes were made. And in the past, with Radeon 9700/9500, they were all R300 chips, and although some pipes were disabled, that didn't change the number of transistors.

Well, i got the info form a reliable source. I also heard that ati totally changed their roadmap because of the nv40!

Hmmm, how do you know that it will "crush" the nv40?

400/1100 for nv40 and it could be either 8x2 or 16x1
600/1200 for x800xt at 16x1 pipes.
I think its a no brainer. ati is not only more effeciant MHz they got 50% higher core clocks :drooling:

Yes, im not saying you are wrong, but is any of this actually confirmed? Do You KNOW that this information is correct?

no one knows at this point, but its common sense that if ati can provide higher clocks with the same 16 pipes as nvidia, they are decidely at an advantage

I agree with you, I cant wait to see how each card performs in the reviews.

Well the Radeon 9500 had 4 pipelines and the Radeon 9700/9500Pro had 8 but they still used the same code name.
