R520 die size

[AthlonXP1800]

If we use that logic, then the r520 is simply a 16pipe card with sm3 probably running at some insane mhz.

Yes you and I seem right predicted the R520 core size and clocik speed.

Industry insiders at IDF revealed:

R520 is nothing more than a 16 pixel pipeline GPU that'll be clocked at 700MHz

700MHz R520 will be XT PE, XT could be clock 600MHz and Pro likely be clock 500MHz. ATI likely will annouce R520 later today but the bad news that it will be paper launch, not the full launch like Nvidia did with 7800 GT and GTX. Yet more bad news, ATI fans wont get their hands on R520 cards when it in stock, ATI will launch R530 mid range card and be in stock first in September. That probably will help ATI make some money while they make as many R520 chips they can, R520 cards will be in stocks in October/November or December at worst.

Here are more surprise Industry insiders revealed:

NVIDIA has a 32-pipe solution it's waiting to pull the trigger on the day after ATI's announcement

Nvidia is waiting to spoilt ATI launch or possible Nvidia could have 7800 Ultra in stocks in September so ATI fans wait for R520 XT PE could find 7800 Ultra 32 pipe end up much faster and bought the card in September that they will no longer bother waste time to get R520 cards. :)

I seem now know the R520 size numbers after read Xbit Labs news (http://www.xbitlabs.com/news/video/display/20050822210504.html) that R520 is very similar size as R480 core.

Let see...

NV40 on 0.13 micron use 222M transistors and G70 on 0.11 micron use 302M transistors, to work out how to add up 222M to 302M figure. The size difference between NV40 0.13 and G70 0.11 is 20% = 44.4, then round to the nearest number which is 40 then 2 times that and make it 80M transistors and add it with NV40 222M transistors = G70 302M transistors. :D

R480 on 0.11 micron use 160M transistors and R520 on 0.09 micron use very similar size as R480, the difference between 0.11 and 0.09 micron is 20% = 32, that mean R520 have 60M transistors more than R480, that total of 220M transistors.

R520 have 220M transistors on 0.09 micron, that the same transistors size as NV40 on 0.13 micron. :eek:

One problem with this is that R480 is on 0.13 micron low-k dielectric, not 0.11 micron, that is reserved for the performance-mainstream R430.

It's also hard to compare as transistor density isn't the same for ATI/NV when compareing their low-k vs no low-k process. If the die size is the same on R520 as R480 I would estimate around ~ 275 mil transistors.

Oh I dont realised that R480 is 0.13, after checked Beyond 3D Tables, you are correct. Let see, difference between 0.13 and 0.09 is 40%, R520 could have extra 120M transistors to make it total of 280M transistors. Very close to your estimate. :D

So wens it supposed to be announced, the r5xx series? and which will be announced first ethu. series or mainstream series?
BTW, i too had posted ~280mil much earlier in this thread :p

I can't think that they'd announce it without a "The best graphics ever is coming soon to a PC near you" campaign. Basically, it just seems really unlikely to me that ATi wouldn't have an ad campaign, and up until now, they haven't - surely they'd start marketing at least a week before product launch. Meh, I guess, if it happens, it happens.

Yes i remember the x800 launch. i got 2-3 mails/newsletters by ruby (ATi) etc. This time, nuthin..no mails, no newsletters, no ads..
