Notice that D700 is right above Radeon 7950, just as in real life. (Wink to Cupertino)Įspecially on a mac where nobody is going to bother writing two different drivers.Īnyhow, specs don't match perfectly but no chance that this isn't a D500 core.ĭ300 is also mentioned in drivers. Just don't believe that your $300 7970 is worth $3,300 because you placed a resistor differently. I'm not saying that there is anything wrong with this, it's how they pay for R & D for a chip once and sell different variants to different markets. I emphasize again, WORKSTATION GPU CHIPS ARE SAME DESIGN AS RETAIL GAMER CHIPS, differences are created via laser cuts and device id s which are changed via tiny 10K or 40K resistors in various positions. ![]() A few features are laser snipped off sometimes, but sometimes just by hard coded device id. Sadly the Unicorn flew off and now they are all made of same silicon on same lines and with same design as retail gamer chips. ![]() ![]() ![]() So likely that nMP card will have same core and a device id very near this one.Įveryone wants to believe these workstation GPUs get special core chips made with Unicorn Hair. I dug out a 7870 I had put together with an EFI rom courtesy of Netkas' help.Īs 666 had noted, it got id'd as FirePro D500. Thanks to a post by 666sheep who noticed this. ![]()
