    What do you mean by that? Nvidia didn't have a Mac version "right out of the gate".

    That also means the 4870s will come down in price. I have a 3870 now, but for OpenCL support, I'd gladly upgrade.

    3870s should be supported in OpenCL. We have no reason to believe that they won't be. Regrettably, 's 4870 won't come down in price, but PC 4870s perfect for the enterprising flasher, will drop like crazy. They already dropped pretty far when the 4890 was announced. They may start being discontinued, though.

    The 3870HD came out for the Mac 7 months after its PC release. The 4870 made its debut on the Mac platform 8 months after it came out for the PC. I wouldn't hold your breath.

    Any takes on possibility to use the card on the 1.1/2.1 MPs?
    Like,is there any structural things that will prevent that generation cards to be used under efi32?

    Getting new card shortly and thinking if I should try to hold out untill the 5xxx series are out or just cave in and get the apple 4870..
    Decisions,decisions...

    There is probably nothing to prevent the 5870 from being used in a Mac Pro.

    The problem is if ATI bothers to put both a 32 bit and 64 bit EFI firmware on the card. Fortunately they did that with the 4870.
    Perhaps the trick is if the 5870 ships with a rom-chip that can hold both of the firmwares.
    4870 did, as we could tell, PC cards were also flashable

    But 285 didnt, and the PC version also had chips too small

    basically if we knew the rom size and the chip size of the 5870, we could tell if a possible mac version would have 32 bit compatibility

    Rumored launch date is September 22nd or 23rd.
    The first table appears to be wrong. I think the Peak Gtexel/s for the HD 5870 should be 43.2 not 86.4.
    Looks like the HD 5870 may actually compete with the GTX 295. The HD 5870 X2 should beat it.

    I would disregard that table. Full of mistakes. Not the correct number of ALUs, wrong TFLOPS, wrong memory clocks etc...

    The Radeon HD 5870 has 1.600 shaders and delivers 2.72TFLOPS.

    Some early benchmarks: [​IMG]

    It was done with Crysis so those are FPS. Almost 15 FPS more than two 4890 in CrossFireX... Tempting!

    Yes but please have in mind that the scores were not obtained on the same system.

    Hence why they cannot be compared like that. The difference can be quite dramatic from an Core i7 to AMDs latest.

    Keep in mind that we got the 4870 approximately 2 weeks before the 4890 superseded it. So, we Mac types had the "latest & greatest" for 2 weeks before something better came out for PC. Months after PCs got them.

    So, the Mac 5870 is probably going to be Spring 2010 or Summer.

    Good news is that so far, all ATI cards have used EBC. (A universal EFI, architecture independent) There aren't a 32 and a 64 bit EFI on these cards, just a single one EFI file that works in either.

    So there is a good chance ATI will keep writing universally useful cards instead of painting themselves into a smaller market, like Nvidia has done. (How many more GTX285s would EVGA sell if they worked on 1st Gens?)

    Get the card you need now, why suffer through 8 months waiting just to find out that Apple got them to do a "64 bit exclusive" ROM to help move new Pros?

    Makes me glad I've held off (Still have the 8800gt in my MP/'08)...

    ...Don't mind waiting til next spring, I'm pretty happy as it is now. Maybe a new release of XPlane "X" or MFS "XI" :)

    It is funny how different platforms execute different FPS...

    My MP in Windows XP runs Flight SimX with the exact same settings and GPU as my Quad core PC....MP....up to 80FPS, the PeeCee...15-17fps!!!! Huge difference (not that anything over 60 cycles is usable....but.....both using the 8800gt), possible more CPU power is utilized by this game....but that is almost a 500% increase in performance!

    +1 This card is at least 7-10 months away from running on a mac.

    At the 1920x1200 res, the CPU won't be much of a factor as it would be at lower resolutions. You might see a 1-2 fps difference at the tested resolution, but the fundamental score hierarchy won't change.

    You will have to be at 2560 x 1600 and higher to not be processor limited with this generation of graphic cards.

    Even current graphic cards can show a big difference between the latest Nehalem versus the latest Phenom II processor. It all depends on the game.

    But it still doesn't change the fact that the scores above were obtained from two very different computers and pasted together in that graph.

    Radeon HD3000 and HD2000 are the same card. They don't have support for sharedl memory which all the nvidia 8000, 9000 and 200 series and the HD4000 have.

    It's extremely unlikely the 3870 will ever support OpenCL as shared memory is mandatory.

    Quite right, also Apple almost NEVER tries to bring older hard BACK into the fold. Once it's last year's model they treat it like an abandoned, homely dog.

    We should get a Mac edition of the 4890 any day now. :(
