Radeon HD 4000 series specs

Hrmm, dont be too harsh on ATI. There X800 series was an evolution of the 9800 Pro, and offered almost double performance over that card - it wasn't a new architecture at all.

But the thing is, the 9800 and the X800 were both good cards ;).
 
Absolutely, but my point is that ATI have always been good with the Evolution of current architecture rather than the implementation of new architecture.

Cases in Point:

9800 Pro to the X800 series - Evolution proved a new top performer, and gave the 6800 Ultra a damn good run for its money.

X1900 vs X1800 - X1800 was barely comparing to the 7800/7900, then the X1900 came away with a clear lead.

HD2900XT to the HD3870 - We all know currently what the 3870 can do for its Price...

So I say roll on ATI, lets see what you can tweak out of the R770 Chip :D

All ATi did with the 3870 is take the R600, shrink it, add DX10.1, SM4.1 etc.., new cooler, 256bit Vs 512bit., it runs cooler and quieter, performance is not much difference with even the 2900XT beating it sometimes.

I'm sure the X1800XT was a good competitor to the 7800 series too.
 
Lol, basically if these specs are true, and they can sample 4x instead of 2x for the AA resolve per clock, they have a winner, because basically the flaws of the R600 architecture were poor texturing power (fixed if specs are true) and a large hit with AA resolve (4x samples would put it in league with the 8800 series more or less).

Also, with the clockspeeds of current cards, you don't need more than 16 ROP's really. I think I saw a review where a overclocked 8800GTS 512mb had more fillrate than a 8800GTX, and almost equal to an ultra.

ati playing the numbers game again i see, slapping a sticker on the box saying 480 shader shoudl help to improve sales.

seeing as how ati's current 320 shader card doesn;t even get up to the 8800gt's 112 stream processors performance, which makes me think that the 480 shaders on r700 should finally give a g92 gts's 128 stream processors a run for the money.


;)
 
Is it me or does the memory speed seem a bit low for gddr5. I thought it could scale between something like 2.4ghz - 5ghz unless they mean 1800 x 2 etc.

Yer but dont forget the estimated 1ghz core. That will help a lot along with the increased stream processors.

yep, missed that one, 1 ghz core speed is gonna give it more fill rate thats for sure.

however im still wondeirng if nvidia will pull out a true next gen card? or will we actually see G90 make its appearance, as in the 24 rop version of the g92 GTS, with the 384bit mem interface.....

only time will tell i suppose.


how long is left now till the new high end cards turn up? is it in august?

But the 3870 is a good card.
Its faster than the 1900xtx+1900xtMaster & they where good cards & it only cost me £160 instead of £650 for the 1900xtx`s

Maybe so, but imo the 2900XT was an awfull card but lets not get into this row again pleeeaase.

if ati go back to a 512bit memory interface then those speeds will probably be overkill, and ddr5 is probably just used to drop down power consumption.
 
Well, it all depends on what people think of "next generation". For example, the 7000 series was just a "beefed up" version of the 6000 series, so i doubt either company is going to do an architectural change on the magnitude that G80 was (and to a less extent the R600).

Yer thats gona be smart. Go off an architecture that probably taken 2-3 years to design and a lot of money. Give it time they will find out its flaws and fix them.

Erm we know the flaws, it's a leaky architecture (VLIW). :confused: a fix would be a new architecture that isn't VLIW simple as.
 
I didn't think there was much wrong with r600 aside from the anti aliasing issue and the power consumption. Both of which were addressed in the 3870, performance hit with fsaa enabled seemed to be minimised somewhat and obviously the power consumption was halfed.

Secondly, why is everyone taking what some random site says as gospel anyway?
