MXSpeed V1.4a (c) 1994 Christian Wagner, Tale Software.

This program performs a VGA ModeX data throughput speed test.

=============================================================================
Test results for: Cirrus Logic GD-54xx VGA
=============================================================================

VGA ModeX CPU  -> VRAM  8bit (stosb) write:  6291 KB/sec.
VGA ModeX CPU  -> VRAM 16bit (stosw) write:  8445 KB/sec.
VGA ModeX VRAM -> VRAM  8bit (movsb) move :  1749 KB/sec.
Speed gain from  8bit to 16bit write:  34%

VGA ModeX VRAM -> CPU  8bit (lodsb) read:  3024 KB/sec.
VGA ModeX VRAM -> CPU 16bit (lodsw) read:  5266 KB/sec.
Speed gain from  8bit to 16bit read:  74%

 8bit write is 108% faster than  8bit read.
16bit write is  60% faster than 16bit read.

Comment: Test results for a no-name Cirrus Logic GD-5426 VGA card.
         This card is pretty fast in reading the Video RAM.
