It’s not truly mobile news, but you’ve gotta love it when the graphics card on a Mac Pro could get an ample boost.
Per Fudzilla, a detailed leak may have given out details of AMD’s mid-range Radeon HD 7000-series desktop graphics. The 7750 and 7750 would sit on the new mainstream Cape Verde Pro and XT cores and each scale back considerably from the higher-end but more expensive Radeon HD 7970. Both would drop from 384-bit to 128-bit memory interfaces and 900MHz core clock speeds.
The differences would come out of shader (visual effect) core counts, texture units, and memory. The 7750 would carry 832 shader cores and 52 texture units fed by 1.25GHz GDDR5 memory (5GHz effective), while the 7770 would up these to 896 cores, 56 texture units, and 1.38GHz GDDR5 memory (5.5GHz effective).
Little was mentioned about the 7850 and 7870 that would sit at the higher end. The two would have wider 256-bit memory buses, additional cores, and higher clock speeds. Either would share the new Pitcairn architecture sitting in between Cape Verde and the Tahiti design in the 7970.
Pricing would be close on the range, most of all in the lower end cards. The 7750 and 7750 would barely be separated at US$139 and US$149, suggesting that one is intended to only show in some retailers or in pre-assembled computers. AMD would reportedly price the 7850 and 7870 at US$249 and US$299 each to appeal to the lucrative upper mid-range gamer segment.
The chipsets wouldn’t arrive until February. If so, they would help determine when many mid-range desktop lines are updated. Apple may use one or more in the Mac Pro, since it’s already supporting the 7900 series in Mac OS X code and would likely want a lower-end graphics card for its base configurations.
Stay tuned for additional details as they become available.
