Also, the power connector on the motherboard is in a different location in the original Mac Pro. For instance, the instructions mention sliding a PCI cage (to move a retention bracket), but the bracket is not present, and the cage doesn't move in the original Mac Pro (each PCI slot has it's own small retention "clip" instead). The only caveat (and it is a very minor one) is that the installation instructions that accompany the card deviate somewhat from what is actually required in the original Mac Pro, due to minor variations between the internals of the older Mac Pros and the newer ones.

It also works just fine in Windows under Boot Camp (after downloading and installing the Boot Camp drivers from the ATI/AMD website). It also performs quite a bit better than the older officially compatible cards. I too purchased one from a local Apple Store and installed it in my original Mac Pro (running OS X 10.6.7), so I can state for a fact that this card does work just fine, and it doesn't require any hacking (no drivers to install, no firmware to be flashed) - it just works right out of the box. Although it is not listed as being officially compatible (and therefore not officially supported), there are numerous accounts in the Apple online store from customers who have reported that the ATI Radeon HD 5770 works just fine out-of-the-box in their original Mac Pros.

That said, there is at least one other card that is currently (as of Summer 2011) available that will work in an original Mac Pro. But the bottom line is that it is not really possible to purchase these cards anymore (except for the super-expensive Quadro FX and maybe a small quantity of the others that can be found used on Amazon or eBay). There are various non-Apple versions of the above, which may or may not work in a Mac Pro, depending on firmware compatibility (sometimes it is possible to program a Mac-compatible version of the firmware into a non-Apple card's non-volatile flash, thus enabling the use of a non-Apple version in the Mac Pro). I believe most, if not all, of the above officially supported cards are all Apple-specific variants. Apple no longer sells any of these cards, except the Quadro FX family (which is super-expensive and not consumer-oriented). Unfortunately, most are not particularly available any more. These are the only cards that are supported in an original Mac Pro. The officially compatible video cards for the original (1,1) Mac Pro are: FreeSyncĪPIs supported, including particular versions of those APIs."Available", "supported", and "will work" are three very different things. This information will prove useful if you need some particular technology for your purposes. OEM manufacturers may change the number and type of output ports, while for notebook cards availability of certain video outputs ports depends on the laptop model rather than on the card itself. As a rule, data in this section is precise only for desktop reference ones (so-called Founders Edition for NVIDIA chips). Types and number of video connectors present on the reviewed GPUs.

Note that GPUs integrated into processors have no dedicated VRAM and use a shared part of system RAM. Parameters of memory installed: its type, size, bus, clock and resulting bandwidth. For notebook video cards it's notebook size, connection slot and bus, if the video card is inserted into a slot instead of being soldered to the notebook motherboard. For desktop video cards it's interface and bus (motherboard compatibility), additional power connectors (power supply compatibility). Useful when choosing a future computer configuration or upgrading an existing one. Information on Radeon Pro 555 and Radeon R9 M390 Mac Edition compatibility with other computer components. Pipelines / CUDA coresĬompatibility, dimensions and requirements Note that power consumption of some graphics cards can well exceed their nominal TDP, especially when overclocked. These parameters indirectly speak of performance, but for precise assessment you have to consider their benchmark and gaming test results. General performance parameters such as number of shaders, GPU core base clock and boost clock speeds, manufacturing process, texturing and calculation speed.
