ATI Radeon X800 Pro and XT Platinum Edition: R420 Arrives

The Cards
Both the Radeon X800 Pro and the Radeon X800 XT Platinum Edition reference cards we received looked exactly the same.
It's very nice to see that this single slot card is equipped with only one molex connector (and in fact require less power than the 9800XT).
The only difference we could spot between the Pro and XT parts was the type of RAM used on each. The X800 Pro used 2ns ram which is capable of achieving 1GHz DDR rates of speed (but is clocked at 900MHz in the X800 Pro)
The X800 XT Platinum Edition makes use of 1.6ns RAM capable of over 1.2GHz DDR speeds.
Each board had 256MB of RAM strapped on board, and though they have slightly different cooling solutions, we were at a loss to locate the difference.
And what is the cost of one of these cards? The Radeon X800 Pro costs $399, and the Radeon X800 XT Platinum Edition will run the standard top of the line price of $499.

Sorry, scrub that last one. I couldnt help it. I will reform.Pumpkinierre - Wednesday, May 5, 2004 - link
So, which is better: a64 at 2Gig or P4 at 3.2?jibbo - Wednesday, May 5, 2004 - link
"Zobar is right; contra Jibbo, the increased flexibility of PS3 means that for many 2.0 shader programs a PS3 version can achieve equivalent results with a lesser performance hit."I think you're both still missing my point. There is nothing that says PS3.0 is faster than PS2.0. You are both correct that it has to potential to be faster, though you both assume that a first generation PS3.0 architecture will perform at the same level as a refined PS2.0 architechture.
PS3.0 is one of the big reasons that nVidia's die size and transistor count are bigger than ATI's. The additional power drain (and consequently heat dissipation) of those 40M transistors also helps to limit the clock speeds of the 6800. When you're talking about ALU ops per second (which dominate math-intensive shaders), these clock speeds become very important. A lot of the 6800's speed for PS3.0 will have to be found in the driver optimizations that will compile these shaders for PS3.0. Left to itself, ATI's raw shader performance still slaughters nVidia's.
They both made trade-offs, and it seems that ATI is banking that PS3.0 won't be a dealbreaker in 2004. Only time will tell....

K, I found the $400M that the CEO claimed. He also claimed $400M for the NV3x core as well. It seemed more as a boast than anything, not particularly scientific or exact.In any case, ATI supposedly spent $165-180M last year (2003) on R&D, with an estimated increase of 100% for this year. How long has the 4xx core been in development?
Regardless, ultimately we the consumers are the winners. Whether or not the R&D spent pans out will play out over the next couple years, as supposedly the nv4x core has a 24 month lifespan.

If you watch nvidia's launch video on their site they mention the r&d costs for their new card.RyanVM - Wednesday, May 5, 2004 - link
What ever happened to using ePSXe as a video card benchmark?Phiro - Wednesday, May 5, 2004 - link
Well, Nvidia may have spent $400M on this (I've never seen that number before but we'll go with it I guess) but they paid themselves for the most part.ATI's cost can't be too trivialized - didn't they drop a product design or two in favor of getting this out the door instead? And any alteration in the architecture of something doesn't really qualify as a hardware "refresh" in my book - a hardware refresh for an OEM consists of maybe one speed notch increase in the RAM, new bios, larger default HD, stuff like that. MLK is what Dell used to call it - Mid Life Kick.

"Precisely. By the time 512mb is useful, the card will be too slow for it to matter, and you'd need a new card any way."True...
Both cards perform great, both have wins and losses depending on the game. The deciding factor will be price and power requirements.
Since prices will adjust downward, at a fairly equal rate, that leaves power. With Power requirements being so incredibly high with the NV40, that leans me toward ATI.
413xram also has a good point above. For Nvidia, this is a 400 million dollar new chip design. For ATI, this was a refresh of an old design to add 16 pipes, and a few other features. After the losses NV took with the heavily flawed NV30 and 35 , they need a financial boom, and this isnt it.

There are no games available today that use 256mb of video RAM, let alone 512mb. Even upper-high-end cards routinely come with 128mb (e.g. Geforce FX 5900, Radeon 9600XT). It would not make financial sense for a game developer to release a game that only a small fraction of the community could run acceptably.>> I have learned from the past that future possibilties of technology in hardware does nothing for me today.
Precisely. By the time 512mb is useful, the card will be too slow for it to matter, and you'd need a new card any way.
