ATI Radeon HD 4800 Series Video Cards Specs Leaked
Thanks to TG Daily we can now talk about the very soon to be released ATI HD 4800 series of graphics cards with more details. One week ahead of its presumable release date, general specifications of the new cards have been revealed. All Radeon 4800 graphics will use the 55nm TSMC produced RV770 GPU, that include over 800 million transistors, 480 stream processors or shader units (96+384), 32 texture units, 16 ROPs, a 256-bit memory controller (512-bit for the Radeon 4870 X2) and native GDDR3/4/5 support as reported before. At first, AMD's graphics division will launch three new cards - Radeon HD 4850, 4870 and 4870 X2:

This is just my way of saying no matter how people HERE feel, look around - nvidia is certainly more popular in the world. Doesnt matter who is better, who is faster - what matters here is that Nvidia is more popular, especially in the DX10 arena.
The argument that got out of hand was because people are saying Nv sucks due to more driver issues.
The response was that there are more Nvidias out there, therefore Nv is not as bad as it appears - this does not mean Nvidia do not have problems, it merely means its exxagerated.
I'm worried about these next gen cards, ATI and nvidia because of these problems. Nv have ditched older cards (i have a geforce 3 and GF4 that no modern drivers work with, they all get stuck in 8 bit color in XP, 7900GT/GX2 have severe driver issues) ATI have fecked up the entire AGP series...
I hope that these new cards coming out, dont mean that yet another old series gets dropped, or the current cards with poor support (AGP ones for ATI) dont get entirely ditched in the process.
Seriously I don't know why people is so crazy about this, for example having to use 4 months old drivers like 169.21 if you want to stay WHQL. And what? They work.
To the AGP people: yes, but you really shouldnt need a hotfix. seriously, its worrying that they cant sort that out. why not release it seperately as an AGP driver, instead of this fussing about.
An example of this is 9800 GTX/8800 GTS and 8800 GT, with the exception that G92 IS indeed BOTTLENECKED by pixel-fillrate at highest resolutions and AA levels. Any improvement to the SP/TMU in this architecture requires an increase in ROPs. That may or may not be the case with HD4000. Since AA is done on the SPs instead of in ROPs there's a lot of room compared to G92, common sense, it's not going to be a bottleneck, increasing everything except that and let it be a bottleneck is stupid and won't happen.
not saying this will ever change, remmber its marketing, if they show acctual numbers for one company and the theo numbers for the other and the diffrance is drastic then people will be more then willing to belive that the one with higher numbers is better.
example of "higher number means better"
was a best buy a some time back, i had a guy from geeksquad try and sell me a 2600xt they had on sale, because "2600xt has got to be better then 1900xtx" after i explained to him that the 2600xt in xfire wasnt even close to as powerfull as my x1900xtx(that was under RMA) he had to go check the net because he ASSumed that higher number=better.
then i went in to bestbuy again, and somebody was asking the diffrance between 8800gt and 9600gt, diffrent geeksquad rep was telling him the 9600 was better because it was newer and had a higher model number.
i had to walk over and explain that the 9600 is a mid range card hence the 6, and that the 8800gt was the better card( due to a sale they where same price after in store rebates and a free gift card) i got unbelving looks, again we went to a net terminal and they checked, the guy bought the 8800gt and thanked me.
oh and to explain, bb here was offering a deal for 3 days, some products you got a nice instant disscont on + depending on price u got XX on a gift card to spend later, basickly its a way to insure you come back, in the end it was a good buy for him since he was replacing a dieing x1950xtx and needed to have a good card told him to rma the x1950xtx and resell it OR just keep it as a backup, then told him he could give it to me :P (i would have rma'd it happly!!!)
well hope that explains what i ment, long story but posted numbers dont alwase tell the real story :P
Another thing is the fill-rate that the cards will achieve in some benchmark. In fact, the benchmark itself has associated its own efficiency factor. In the end it doesn't matter because within the same architecture the efficiency will be the same or very close. If HD 3870 has a performance hit of X, you will have the same on HD3850 and the same in HD4000 cards because it's the same architecture. If HD4000 is double as fast in paper, it will be double as fast in applications once that driver and platform bottlenecks are fixed.
cor PLEASE be true - PLEASE!!!!
I still dont get why they bother with SP Crysis. Has the hype really grasped the masses ?
I thought that whole piracy being the cause for low sales was a load of crap. MP was a total disaster, and it almost seems as though the games only use is for benchmarking. <--< See, even i assume!
Its only a matter of time before the gpu technology reaches cpu efficiency and power, with multiple cores. The technology already exists, the knowledge is there! Just a matter of time and OUR money :P
As far as power conservation,,,,,hell with it for me, I don't care about saving energy with my computer for what little it amounts to. Give me more power at any cost. AMD needs to get back into the elite club in every aspect. The past year they have let me down and delayed my upgrades....b*st*rds. This new 4870 (X2) sounds real promising.......they better come through!!!
