AMD’s RS780 and Nvidia’s MCP 78 IGP chipsets are scheduled to go head-to-head in the first quarter of 2008, however, performance of the MCP 78S is reportedly below that of the RS780, while the higher-end MCP 78U is causing issues due to its higher thermal dissipation giving AMD the advantage over the chipset battle, according to sources at motherboard makers.
The RS780 is reported to have 15-20% better performance than the MCP 78S in 3DMark 05 and 06 tests, while the higher-end MCP 78U cannot function normally with the original passive northbridge heatpipe due to the higher core frequencies of the graphics engine. Adopting a larger heatpipe or fan will cause costs to rise significantly, pointed out the sources. Nvidia is still struggling with the problem, they added.
Additionally, motherboard makers have not yet taken delivery of MCP 78 chipset supplies, which means that the original launch schedule of motherboards might have to be postponed back to the end of January or beginning of February, noted the sources.
IGP Wars: AMD upperhand on NVIDIA
Upcoming battles between the IGP chipsets from AMD, the RS780, and NVIDIA, MCP78S, are apparently leaning towards AMD for performance. This is all according to motherboard makers in Taiwan.
