As I have already mentioned, three products out of five (GTX 280/260, 9800 GTX+) are just reference cards. So we shall not examine them in full detail.

But both modifications of the 9500GT have original design. For one, we'd like to complain that the manufacturer has again rolled out two cards with the same name. Moreover, they don't use suffixes to show their different memory, so the manufacturer has to mention memory type in the card name. For two, I don't understand why 9500GT GDDR3 has such a sophisticated design, the card is too expensive compared to its competitors. Besides, why use 8 memory chips of lower capacity instead of just 4 chips with a 128-bit bus? Can it be that eight 512Mbit chips are cheaper than four 1024Mbit chips? I'm not sure. So I don't get the whole idea behind it. The design of the GDDR2 modification is obvious, as it's also similar to the reference design to some degree.

Don't forget that 9500GT products cost less than 80 USD, so their manufacturing costs must be very low.

All cards have original TV-Out interfaces that require a special adapter to output video to a TV set via S-Video or RCA.

An analog monitor with a D-Sub (VGA) interface can be connected by means of a special DVI-to-D-Sub adapter. Also bundled are DVI-to-HDMI adapters (these graphics cards support video/audio output to HDMI receivers), so there should be no problems with such monitors.

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)

As of HDTV, a review is available here.

All of these cards but GeForce 9500GT require additional power sources, so each is bundled with a molex to 6-pin (or 8-pin) adapter, even though all modern PSUs are equipped with such cables.
