There will be two versions; the MCP85-S and MCP85-V. The main difference will the difference in PureVideo version and clockspeed:
MCP85 is a mainstream chipset for AMD CPU. It will be placed right at the positions of GeForce 8100/8200/8300 (MCP78). The main reason to roll out MCP85 is to support AM3 CPU, and to keep the Hybrid SLI plan on track, trying to use Hybrid Power and GeForce Boost to sell more entry-class graphic cards.
MCP85 has two versions, they are MCP85-S and MCP85-V. Two versions looks the same, the only difference of MCP85-S and MCP85-V will be their clock and PureVideo versions, you can see our charts for details. I’ve noticed that the amount of the shader processors are only 8 (16SPs in MCP78).
Both MCP85 and MCP82 will support ACC overclock, that’s a good news for AMD CPU users, because having ACC supported means more headroom for overclockers.
