IGP Wars: AMD upperhand on NVIDIA
Subject: Chipsets | December 31, 2007 - 04:48 AM | Ryan Shrout
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.
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.
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.
