Rumour control: AMD / ATI RV770 release date revealed

Posted at: 10:36am 13th March 2008 by Ben Hardwidge

The first genuinely new architecture from ATI since the Radeon HD 2900 could be out in a few months

It’s about time that AMD / ATI developed a new GPU architecture; we liked the Radeon HD 3850 when it came out, but there’s no getting around the fact that it was basically a Radeon HD 2900XT after a die-shrink, with added DirectX 10.1 and PCI-E 2.0 support. However, if the rumours are to be believed, then the next ATI chip could be out by the end of June this year.

The Taiwanese gossip diggers over at DigiTimes report that AMD has recently told its partners that it expects its share in the graphics card market to jump from 35 per cent to 50 per cent. The reason? Apparently, because the RV770 will be available at the end of the second quarter of 2008. DigiTimes cites sources at graphics card makers for the information.

There has been a lot of speculation about the specs of RV770, but we haven’t seen anything that looks legitimate yet. The guys at VR-Zone reported today that the chip will have 800 stream processors, made up of five arrays of 160. Meanwhile, Nordic Hardware reckons that it will have 480 stream processors and 1GB of GDDR5 memory, and that the top chip will be called the Radeon HD 4870. We don’t believe a word of either of the above at the moment, apart from perhaps the name, but we’re liking the idea of a new ATI architecture being released in a few months.

lets wait n see eh

Well only time will really tell eh, and its about time ATI came up with something special as nothing brilliant has been bought out by them in a while now.Now everyone is going on about ATI's 3800 series being 320 stream processors , well actually its 64 stream processors with 5 way calculations, that is not a 5 way full calculation , if that stream processor makes a mistake it has to start all over again which means that the branch prediction is not good enough, and really the 5 way needs to be 5 different calculations run at once to call it proper 5 way.So really the 3800 series does quite well for 64 proper stream processors.I believe that this new R770 will be 6 lots of 128 stream processors which means 768 in total, now that would be good and in theory should be able to run crysis at 60fps but we will have to wait n see eh.Now if ATI are going back to the original R6 series of GPU idea before AMD cocked it up for them then it would really be 6 banks of 32 stream processors with 4 way calculations and if they have good branch prediction then it too could still in theory be powerful.Also note that Current ATI cards do not have enough ROPS to output the power of the R670 series to the screen so lets hope AMD sort that out too or this next R770 will not perform as well as it should as the ROPS will not be able to draw it to the screen.Lets hope say 24 ROPS min and if it is that powerfull then 32 would be good, then the R770 might well end up being an exceptional card ,if not yet again ATI will be underperforming for the power of the card purely because the ROP's cannot draw what is calculated to the screen and will mean yet again dropped frame.Now only time will tell the real story once the R770 has been tested on nowadays games.Maybe this time ATI have listened and kept quiet about what they have and not given away info that means that Nvidia just bring out something to better it quicker than ATI.

blah blah blah

ati's can have 1200 stream processors, if they still hang on to 256 bit memory then they gonna get kicked by nvidia again... 512 bit bus + 1gb gddr5 memory FTW

GDDR5

Hardly any of them use gddr4 never mind 5... 800 Stream processors ? so what nvidias 8800GT uses 120 odd and kicks three bells outta the Ati ones with over 300 ?

i think CRYSIS is too buggy to play at 60FPS, but we'll have to wait and see for that, although now we may see much more power efficiant GPU's which will be much better meaning we will see better PSU's coming out running at 650W 95%, which would be great, because 1000W is just too much power drainage and not really required unless you run a 2900XT in Dual Crossfire, and also less power requirements would be great in terms of low audible cooling, i am focusing on power because AMD seem to keep on going on about this "energy saving" hardware.

Ooooh

I heard the RV770 will be 2 bars of soap wrapped in rice paper. It'll have 960 stream processors etched into the soap using a magenta laser. But will it play Crysis at a min of 60fps???

Sounds good. Let's hope it can take on Nvidia and give them some competition at the top end.

haha.. was up way too early

not cold enough to wear an anorak thank you.. just the notion that your slang would actually sink in to the commons mans brain makes methinks you might have an anorak in the closet yourself! haha i had to wikipedia it because i thought it was a jacket but i just didnt get it! Bravo my good man!
