First, if you’ve never heard of a Fire Pro D300, don’t feel bad — that card doesn’t show up anywhere on AMD’s spec sheets. With the company currently rebranding its Radeon hardware, it’s clear that a Fire Pro rollout is imminent as well. The new D300 is most likely a W5000 card — that’s a lower-end workstation GPU with 768 stream processors built on a 256-bit bus, with 2GB of RAM. Apple is claiming 2.7TFLOP of performance, which would match the combined output of a pair of W5000s, making them even more likely.​

Now that Mavericks has been released I would like to talk about the possible compatibility of some AMD GPUs on a Hackintosh besides the FirePros that go with the new Mac Pro.This GPUs are the R9 xxx Series for example the R9 280x and the 29 290X and in fact share many similarities with Mac Pro’s FirePro GPUs. I think this is very interesting since AMD R9 graphics cards retail at half price of Nvidias cards. This way it would be affordable to make a CrossFire configuration with these cards and double the performance of for example the GTX 780 getting to the level of the graphic power of a Mac ProI found a post where somebody finds similarity between R9 lineup (the R9 270x and the FirePro W7000 with the D300 from Mac Pro’s FirePro unreleased GPUsI extract the next paragraph from an article on extremetech.com that also points out some similarities between the same D300 Mac Pro’s FirePro graphics cards and other that are already released by AMD ( http://www.extremetech.com/computing/169239-apples-new-mac-pro-december-3000 We know that as not certain as all these may seem, (since both see similarities with different models but they are not 100% sure) both AMD and Nvidia reuse the same component across more than a single card. Now that said, do you guys think R9 GPUs could be compatible with Mavericks? since they share some features with the new Mac Pro’s GPUsI would like to know more about this matter and know your opinion. To me this would be the real deal for my Hackintosh and if this is so I am sure many of you would be interested too. Lets hope AMD releases this new GPUs that have only be seen on the Mac Pro sooner or later if all of the above isn’t enough for a Mavericks compatibility on our Hackitoshes.
