    Mufu can you sum up the future Ati chip coming till the end of the year (that you know of). I'm a bit confused ATM.

    Thx very much!

    [speculation mode] Well, if there is another R3*0 chip on the way later this year I would expect that it will be a 0.13 micron version (possibly low-K process?) with the usual tweaks to improve performance and then clocked at 500/500 or possibly slightly higher? [/speculation mode]

    Yeah, that would be my guess too. An 8x1, 0.13u (>3.0-k) ASIC based largely on RV350 tech.

    Seem to be rather a lot of hints being dropped re. a MAXX implentation as well. Not quite sure what to make of them... =\

    They need something to compete feature-wise with NV40 next year though, hence my curiosity about "R420".

    a MAXX version, really think they would try that route again?

    If I was ATI, I would capitalize the sucess of R300 & DX9, provide fine tuned HW/SW gaming/3D platform, speed, stability and compatibility are key to ATIs mid-term sucess, especially when DX9 & DX9 hardware become mainstream in about a year or primary configuration in 2 years time. When DX9 game isn't coming out in months, DX9+ features are just marketing tools. I believe developers like to see the platform evolution stop for a while too.

    So my conclusion is don't go too fast ATI, work on DX9 platform, make it better first and then bring us R500 the big leap forward a little later. As ATI share holder, my view might not interest you enthusiastic, sorry in advance.

    ATI Generation's

    ATI Radeon

    Original R100 0.18 micron 183MHz chip
    SDR & DDR 183MHz
    128bit memory

    Original R200 0.15 micron 275MHz chip
    DDR 275MHz
    128bit memory


    Now here comes Successful GPU/VPU chip's
    R300 0.15 micron 325MHz chip
    DDR 310MHz
    256bit memory

    R350 0.15 micron 380Mhz chip
    DDR 340MHz & DDR2 approx guess ~400MHz
    256bit memory


    R400 0.13 micron approx guess ~400MHz - 500MHz chip
    DDR2 approx guess ~400MHz - 500MHz
    256bit memory


    R500 0.09 micron approx guess ~600MHz - 700MHz chip
    DDR3 approx guess ~600MHz - 700MHz
    good guess will be 256bit or 512bit memory

    This looks way off. I'm thinking it'll be 500MHz upwards. We're already at 400ish with the R300, the only thing to note is that R400 is supposed to be a big deal, i blieve that's what Mr. Orton said.

    I said that sorry.

    Look at Nvidia Geforce FX 5800 Ultra 500MHz chip... It's running Hot!!!

    Boy it need's big cooling system; unless ATI comes up some-kind design
    that the chip won't run that HOT...

    Off the topic (Sorry)

    Could ATI come up with Duel channel DDR solution or QDR I guess you could say that...

    Intel coming out with i875P Canterwood chipset (Duel channel DDR400 solution)

    Can they make it with video cards.

    The current video cards already has multiple memory channels, for instance the Radeon 9700 has four 64bit memory channels.

    Then how come they/ATI never called QDR memory for their video cards.

    But continue to be DDR, DDR2 and etc...

    But where then QDR, QDR2 and so on.

    That's great, and this means what?

    You do realise the designs are very different.

    -The NV30 has how many more transistors than the R3XX?

    -What process are the R3XX and NV30 using?

    Also, it's worth noting that, ATI has had a track record of producing cooler chips than their competitors in the same generation. But back to fabrication and performance.

    -What speed does the R350 run at and what cooling does this require?

    -What's the clock disparity between the two?

    If you start adding things up, you'll realise how big an advantage ATI has. I'm very sure ATI can get much higher clock rates on the 0.13 and it won't need exotic cooling.

    When it comes to heat dissipation ATI likely has and has had a noticable advantage.

    Just look at this?

    ATI R350 = Default clock 380MHz (0.15 micron could handle approx 425MHz stable = MAX) that's it.

    Nvidia NV30 Ultra = Default 500MHz (0.13 micron could handle approx 525MHz stable = MAX) that's it.

    How far do you think ATI could take their 0.13 micron R400 chip; plus make it cooler running then Nvidia's...

    Just think about it.

    Ugh, so they can get within 80% of their clockrate with lesser cooling. You're telling me they can't close that fairly small gap and get a fair bit more by going to the 0.13u process?

    Every 0.xx micron technology has it limits?

    For example:)

    The reason ATI is going to move from 0.15 micron to 0.13 micron is Theatrically 0.15 micron STOP's at 400MHz speed; but 0.13 bypasses that limitation. AND Theatrically 500MHz is about an avearge range where 0.13 micron also reach it's limits.


    So ATI is thinking ahead for their R500 chip.

    Theatrically 0.09 micron technology could easily reach 600MHz GPU speed, but might have diffculties reaching over 700MHz speed.

    Because 0.09 micron technology has its limitation; theatrically an evearge range would be 700MHz before 0.09 micron gets Hiccups.

    Then you would need 0.07 micron technology to go over easily 700MHz, but Theatrically 0.07 will get you about to 800MHz before you would have
    dificulties again of going higher clock frequencies.

    Um... do you know anything about feature size and transistor switching speeds? Honestly?

    Your numbers are well, basically out of your ass from uneducated guesstimates from comparing designs from two different companies which have little in common and their track records are disimillar.

    I'm not going to get into a pissing contest, but there are a lot of things, besides FEATURE size that can increase a designs clock rate. Basically, what I'm saying is that ATI is better in this department by a fair margin and thus will beat out Nvidia's clock rate and heat dissipation accomplishments as demonstrated by the NV30. Hell I suspect Nvidia will/could beat out Nvidia if they took another whack at it.

    I did Mathematically count.

    You would say huh... but this is just me, I like math...


    Off the topic:)
    ATI R300 chip has 110 million transisitors, what ATI wanted is to double in
    R400.

    Thanks for your time. Good luck:)

    The honest truth what I know is; by switching from 0.15 micron to 0.13 micron gives ability to get higher clock Frequency's.

    Their is no way on earth you could get 500MHz GPU speed on 0.15 micron technology.

    So you have no choice; ---> you have to shrink the die to 0.13 micron.

    So ATI will / not question about it ---> for there R400 ---> 0.13 technology.

    My believe R400 will be about or close to 500MHz GPU/VPU core speed.
