Answer
Software 3D is generally used to mean using non-specific (2D)
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 as compared to ordinary DRAM?
Answer
is now capable of running at much higher speeds than Fast Page
Mode or EDO DRAM. Also, is able to execute a small number of
frequently executed operations, such as buffer clears, specific to
graphics applications, independently of the controller.
3D Glossary
Definition and Terms from A - Z.
Accelerator
A specialized piece of hardware dedicated to increasing the
speed in which graphics operations are performed.
AGP
The Accelerated Graphics Port (AGP) interface is a new
platform bus specification that enables high performance
graphics capabilities, especially 3D, on personal computers at
mainstream price points. AGP is a high-bandwidth 32-bit bus
which operates at 66Mhz and transfers data at a speed up to
528MB/sec, compared to the PCI slot which runs at 33MHz
and has a maximum transfer rate of 132Mb/sec.
