"Oland" will be built in 28 nm, but feature a substantially larger die than the current Pitcairn core and promises a sizable performance increase. The price may be the big surprise in this release.
The transistor are size will jump by 27 percent to 270 mm2 and the transistor count for both the HD 8850 and HD 8870 will grow to 3.4 billion. The base clock will be lifted by 7 percent and 5 percent, respectively, to 925 MHz and 1050 MHz. The single-precision computing performance is promised to increase by 70 percent to 2.99 and 3.94 TFlops, while the double precision count is indicated as 187 and 246 GFlops. AMD was apparently able to contain the power consumption of the cards and shave off 15 watts on the high end to arrive at 160 watts.
The most interesting part in the leaked table, if the information is accurate, is certainly the pricing, which is much more aggressive than before. The higher-end 8870 is listed for $279, while the 8850 has a $199 MSRP. This information is not confirmed, but certainly intriguing and an interesting play for AMD.
