Technology is fascinating. An engineer
will come up with a new technology that allows
for a significant increase in performance over
existing technology, as with the NVidia GeForce.
As the new platform matures, the speed and
throughput of given device is realized and the
limitations are exposed. At that point,
another brilliant engineer sets out to improve
again on the initial design in an effort to
alleviate the bottlenecks and achieve yet an
even higher level of performance. As we
all know, this process happens at an alarming
rate in the Computer and Networking Industries
as well as Semiconductors.
memory bandwidth was an initial bottleneck for
NVidia GeForce chipset based 3D Graphics
cards. It was a bottleneck that was
envisioned early on by NVidia however.
They designed the initial GeForce architecture
to be capable of interfacing to a new high
performance SDRAM and SGRAM with double the data
rate of current standard DRAM
architectures. DDR SDRAM/SGRAM, or Double
Data Rate Synch DRAM, allows any device
interfacing to it to perform reads and writes to
the DRAM on the rising and falling edge of the
memory clock cycle. With each clock cycle,
you can perform both a read from and a write to
the memory. As a result the effective
throughput of the DDR SDRAM is doubled.
Hence the term, "double data
is the technology behind both the DDR SDRAM and
DDR SGRAM. SGRAM is Synchronous Graphics
RAM that is configured to cater to the needs
of 2D/3D Graphics designs. It is
comprised of the same basic cell technology of
