The Asus EN8800GT TOP/G/HTDP/512M/A videocard is powered by
the nVIDIA GeForce 8800GT core. Code named 'G92', this graphics processor is a big slab of silicon. It's manufactured
by TSMC on the 65nm process and contains 754 million transistors - wow! Nvidia packed the G92 core with some tweaks that
other GPUs in the Geforce 8800-series have lacked. The Geforce 8800GT integrates a
video processing engine (which was previously a separate chip with G80 versions
of the GF 8800GTX/GTSs) into the core, and increases the number of texture
address units.
Since the nVidia G92 core is based on
the same technology as the previous GeForce 8800GTX/GTS GPUs, PCSTATS will do a
brief overview of the differences in this review. We know you're not going to read pages of technical
jargon, and frankly we're not going to write that much in
place of time with benchmarks.
First off, the nVidia G92 core has 112
stream processors available to it (128SPs for the 8800GTX, 96 for the 8800GTS
640/320MB model) which means clock for clock the G92 is technically more
powerful than the GeForce 8800GTS. Thanks to the smaller 65nm
manufacturing process, the G92 core runs quite fast: 600 MHz (700MHz on the Asus
EN8800GT TOP/G/HTDP/512M/A).
The GeForce 8800GT's 512MB of memory is
clocked at a very high speed, 1800 MHz (2000 MHz with this Asus videocard). This
is faster than the 8800GTX. To ensure that the G92 stays in its place, behind
the 8800GTX, nVIDIA purposefully equips the new darling with a small 256-bit
data bus. The GeForce 8800GTX uses a 384 bit bus (50% wider) and the 8800GTS
320/640MB a 320 bit data bus. That should keep the GeForce 8800GT performance in
check.
For those who like theoretical numbers,
the nvidia GeForce 8800GT GPU boasts a texture fill rate of 33.6 billion per second and
a bandwidth of 57.6 GB/s. The GeForce 8800GTX comes in at 36.8 billion per
second for texture fill rate, 86.4 GB/s in bandwidth. The GeForce 8800GTS weighs
in with a 24 billion per second texture fill rate and 64 GB/s
bandwidth. Now, let's overclock this
pre-overclocked Geforce 8800GT from Asus shall we?
