VIA CoreFusion is a line of low power
x86 processors manufactured by
VIA starting in 2003. The Corefusion integrates the
Northbridge, graphics processing unit and a V-Link Interface (Luke and John only.)
The Corefusion platform is available in four varieties: Mark, Luke, Luke-Lite and John.
Mark
The Corefusion Mark was released on March 12, 2003. The processor core is based on the VIA C3
'Nehemiah', and includes the VIA ProSavage CLE266 Northbridge and the S3 Graphics
ProSavage4 graphics processing unit. It supports 133 MHz
SDRAM
Synchronous dynamic random-access memory (synchronous dynamic RAM or SDRAM) is any DRAM where the operation of its external pin interface is coordinated by an externally supplied clock signal.

Front side bus
A front-side bus (FSB) is a computer communication interface (bus) that was often used in Intel-chip-based computers during the 1990s and 2000s. The EV6 bus served the same function for competing AMD CPUs. Both typically carry data between the ...

Luke and Luke-Lite
The Corefusion Luke was released on 8 March 2005. The processor core is based on the VIA
Eden-N, and includes the VIA CN400 Northbridge and the S3 Graphics
Unichrome Pro graphics processing unit. It supports up to 400 MHz
DDR SDRAM.
The Corefusion Luke-Lite is nearly identical to the Luke, with the only difference being the integrated Northbridge is replaced with a VIA CN333. This limits the maximum memory speed to 333 MHz (versus the 400 MHz on the Luke.)

John
Little is known about the Corefusion John, other than a VIA roadmap PDF from 2005 foun
here. It was apparently planned as a successor to the Luke, and supposed planned features were to include DDR2 support, hardware WMV9 decoding and HD audio support. It is unknown if this part was ever released, but it likely would have used some variant of a VIA C7 core (since VIA lost licenses required to produce the C3 series.)
