hardware in conjunction with the CPU to render for 3D
applications. Some of these techniques allow usable 3D
applications when high-powered and/or MMX™-equipped CPU’s
are employed along with special-case software optimization
techniques. As stated above, SW 3D can achieve credible results
with today’s (software optimized) applications, but the rising
popularity of good 3D hardware at the consumer price level is
inexorably compelling the public to expect hardware level scene
enhancements and frame rates.
Q7
What is “SGRAM”?
Answer
Synchronous Graphics Random Access memory (SGRAM) is a
new and improved type of memory, custom-designed for graphics
use.
Q8
What is the advantage of SGRAM as compared to ordinary
DRAM?
Answer
SGRAM is now capable of running at much higher speeds than
Fast Page Mode or EDO DRAM. Also, SGRAM is able to execute
a small number of frequently executed operations, such as buffer
clears, specific to graphics applications, independently of the
controller.
