"The NVIDIA GeForce GTX 280M has 128 processing cores,
has a texture fill rate of 38 billion/sec, 1463MHz processor clock,
a memory clock up to 950MHz and up to 1GB of GDDR3 video memory
with a 256-bit bus, and its peak memory bandwidth is 61GB/s. Other
features for this notebook GPU include two-way SLI support, NVIDIA
PureVideo HD, NVIDIA PhysX, NVIDIA CUDA, NVIDIA HybridPower, OpenGL
2.1 supportive, and PowerMizer 8.0 power management. The GeForce
GTX 280M is compatible with HDMI, dual-link DVI, DisplayPort, LVDS,
and VGA outputs. HDMI audio is also supported via an S/PDIF input.
"Behind the GeForce GTX 280M is the GeForce GTX 260M and GTS
160M. The GeForce GTX 260M has a core clock of 550MHz compared to
585MHz with the 280M (though the memory clock is the same), and 112
processing cores compared to 128 on the high-end model. The NVIDIA
GeForce GTS 160M is limited to 64 processing cores, 600MHz core
clock, and 800MHz memory clock.
"For providing these initial benchmarks of the GeForce GTX 280M
under Linux we used the System76 Bonobo Professional that was
loaded up with this discrete notebook GPU, an Intel Core 2 Quad
Q9000 clocked at 2.00GHz, an Intel 4-Series motherboard Chipset
with ICH9M Southbridge, 4GB of system memory, and a 320GB Hitachi
HTS72323 SATA hard drive. We will be featuring a complete review of
this System76 notebook in the next week. On the software side we
were running Ubuntu 9.04 x86_64 with the Linux 2.6.28 kernel, X
Server 1.6.0, and the NVIDIA 185.18.14 display driver."
