Japanese media has got a hold of the specifications table of AMD's
Radeon HD 7800 series products, the HD 7870 and HD 7850. Hermitage
Akihabara has not cited a source as such, so we assume it vouches for
the accuracy of this table. The table reveals Radeon HD 7870 as having
1280 stream processors, a 256-bit wide memory bus width (derived from
the memory bandwidth and clock speeds figures provided in the table), 80
TMUs, 32 ROPs, and clock speeds of 1.00 GHz core, with 1200 MHz (4.80
GHz effective) memory. This SKU has a typical board power of 175W.
The slide details the HD 7850 as having 1024 stream processors, 64 TMUs,
32 ROPs, the same 256-bit GDDR5 memory interface, with the same memory
clock speed as the HD 7870, but with a lower core clock speed of 860
MHz. the board power for the HD 7850 is mentioned to be under 130W.
Interestingly, 2 GB is standard memory amount for both cards. The
Japanese site mentions the official launch date of HD 7800 series as
being March 8, but also goes on to add that market availability (we're
assuming they mean the Japanese market), is only expected on/after March
19.
