Nvidia President Jen-Hsun Huang explains why the RSX graphics
processor, along with Sony's Cell processor, will help drive graphics
into the next generation.
OPM: How does the new processor compare to the GPU in the original Xbox
or the ATI GPU's in the Xbox 360 and the Revolution?
Jen-Hsun Huang: The GPU in the original Xbox was phenomenally powerful
and flexible for it's time but is quite primitive compared to modern
programmable GPU's. GPU performance has been doubling every six to nine
months, and since the original Xbox is approximately 5 years old, one
would expect modern GPUs, such as the GeForce 7800, to be approximately
50 to 100 times more powerful, and in fact they are.
OPM: What would you say is the key difference between the RSX GPU and
previous Nvidia products?
JH: PC graphics and core-logic products must be flexible and work
efficiently and reliably in a variety of system configurations. This
flexibility forces the GPU designers to be prepared for a wide variety
of workloads so that a PC
product can be very good at very many things. The RSX is designed to
work closely with [the Playstation 3's Cell processor] in a
closed-system environment.
OPM: Can you briefly explain how the Cell processor works in tandem
with the RSX GPU? Is the Cell processor a good fit for the RSX?
JH: The Cell processor has multiple processors that can execute
different threads and produce geometry, texture, and shader information
for the RSX to consume. Since the RSX is so powerful, in some cases it
will take almost the full performance of the Cell just to keep the RSX
busy. The Cell processor has enormous floating-point processing and
throughput capabilities and is an excellent engine for physics,
gameplay, and other nongraphical tasks. The RSX is designed to be a
powerful, efficient companion processor to the Cell.
OPM: There is some speculation that many of the demos shown at E3
couldn't be done in real time on the PS3 hardware. Do you think this is
true?
JH: There's no question the demos are possible on PS3 hardware.
