This article is devoted to new graphics cards from Gigabyte. We have two products based on NVIDIA GPUs from different price and performance ranges: GeForce GTS 250 (aka 9800 GTX+, based on the good old G92) and GeForce GTX 275 (an intermediate between GTX 260 and 285, closer to the latter in terms of speed).

Gigabyte GeForce GTS 250 Overclocked 1024MB

The graphics card has 1024 MB of GDDR3 SDRAM allocated in 8 Hynix memory chips on the front side of the PCB. These memory chips are designed for the maximum frequency of 1250 (2500) MHz.

Gigabyte GeForce GTX 275 Durable 896MB

The graphics card has 896 MB of GDDR3 SDRAM allocated in 14 Hynix memory chips on the front side of the PCB. These memory chips are designed for the maximum frequency of 1250 (2500) MHz.

The GTS 250 is apparently a unique card designed by Gigabyte. Although equipped with a 256-bit memory bus, this PCB is designed as short as possible. On the other hand, it comes with a massive cooling system (to be described below). It should be added that the card allows to adjust its operating frequencies and voltages with a special utility.



GTX 275 is an original product. Its PCB only looks like reference (even though it's manufactured by Gigabyte, not purchased from NVIDIA as a ready product). In fact, this PCB is heavily modified (layout, protective screens and their quality, power supply). Power consumption is lower now (as PSU components consume power as well as like core and memory chips). The company promises lower operating temperatures and stability. We'll analyze temperatures below, and operating stability of this card is really high. We could even overclock the core to 750/2000 MHz without ruining stability. It really works.

The GTX 275 card has a TV-Out for an S-Video cable. And the GTS 250 has an HDMI output.

Maximum resolutions and frequencies:

  • 240 Hz maximum refresh rate
  • 2048 x 1536 x 32bit @ 85Hz Max - analog interface
  • 2560 x 1600 @ 60Hz Max - digital interface (all Dual-Link DVIs)

The HDTV review is available here.

All cards require additional power, so each is bundled with a molex to 6-pin adapter, even though all modern PSUs have with such cables.
