nVidia G92 GeForce GTS 250 Core
ENGTS250 DK videocard is powered by the nVidia GeForce GTS 250 core. Code named
'G92', this graphics processor has been around the block a few times, in
the form of the Geforce 8800 GTS 512, the 9800 GTX and the
This has seen the G92 core die-shrunk
from 65nm down to 55nm, as well as reductions in its overall power consumption
Since the nVidia G92 core is based on
the same technology as the previous GeForce 9800GTX/GTX+ 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.
the nVidia G92-421-B1 core now has an overall core clock speed of 740MHz and
a memory clock speed of 1836MHz. While the overall clock speeds have
increased, the G92 core still retains the overall 128 stream processor cores from its
For those who like theoretical numbers, the nVidia GeForce GTS
250 GT GPU boasts a texture fill rate of 47.2 GTexels per second and a
memory bandwidth of 70.4 GB/s. Compared to the rival AMD Radeon HD 4850, which
has a fill rate of
20.8 GTexels/s and 73.2 GB/s of memory bandwidth.
nVidia videocards are still a step behind their AMD counterparts when it comes
to HDMI video output over the DVI ports. While both companies' latest
videocards support hardware video decoding, nVidia still hasn't included an
audio codec on its new Geforce graphics cards. This means that the included
DVI-to-HDMI adapter has to be used with an S/PDIF header in order to output the 7.1 channel
audio stream. This makes for slightly messy cabling, but shouldn't be a
problem as long as you remember to plug the HDMI adapter into
the yellow DVI output on the Asus ENGT250 DK's I/O panel.
Two & Three-way nVidia SLI
nVidia's Scalable Link Interface has undergone constant updates to improve its performance and compatibility with recent games, as well
as add to its overall feature set.
The Asus ENGTS250 DK has two SLI connectors, so it
can be paired with either one or two more Geforce GTS 250 videocards. The
older Geforce 9800GTX+ videocard is also supported in SLI mode, as long
as both videocards have the same amount of video memory.
The most recent major update to nVidia's SLI technology
finally adds supports for multiple monitors while SLI is enabled. This is great
for games that scale well with multiple GPUs and can also take advantage of
multiple monitors, like Supreme Commander. The Geforce GTS 250, like the Geforce 9800GTX+
before it, can be run in two or three-way SLI configurations, although the
amount of additional performance diminishes significantly once a third videocard is
Support for SLI is limited to the Intel X58 chipset and nVidia SLI chipsets
only, and for maximum performance these chipsets should have at least x16/x16 of
PCI Express bandwidth. nVidia claims that this new revision of the Geforce G92
graphics core draws less power than ever before, so lets see how true
that is, next!
