 I've noticed that most new 486SX PC clones offer VGA with local bus
hardware for CPU/VGA-card communication.

 If one decides to stick to Windows and gets a good Windows/VESA
driver with the computer, will a VESA solution generally be much
faster than a system with an ISA bus operating at a higher speed
than 8 MHz? (Many clones feature an AT bus speed option in the
BIOS setup menu.)

 Also, if anyone could explain the major differences between
the two solutions, I would really appreciate it. I've used some
computers over the years ever since I bought an 8-bit Atari back
in 1983. In that computer, the CPU and the graphics chips shared
the same memory with a noticeable CPU slow down during graphics
DMA. It appears to me that a PC/ISA computer is not slowed down
during video memory scan, which isn't too surprising since VGA
cards seem to have their own memory. On the other hand, CPU access
to VGA video RAM is noticeably slow.

 Now that VESA is introduced, what will we end up with? Will we get
faster (memory mapped) CPU access to video RAM with the slow-down
caused by a shared bus as a result?

 Thanks in advance for any hints on this.
