Mac Pro FirePros with weird specs, thoughts
Just a thought about the FirePros that seemingly aren't like other FirePros (from the memory bus/shader core/etc configs, the low and mid end don't exist in the FirePro line). On Windows, the distinction between Radeon and FirePro is mostly driver level, FirePros do also support ECC memory but not all FirePros have that. On OSX, Apple writes much of the graphics driver themselves, so perhaps the distinction between the two is less important for that reason, plus with a smaller pool of GPUs in macs pro applications certify more of them (as a percentage at least), so consumer level GPUs are supported more in pro apps.
So my thinking was, could these just be Radeon configs, rebranded and re-drivered with FirePro?
