Inno3D GeForce GTX 275 OC 896M Review 6

Inno3D GeForce GTX 275 OC 896M Review



Inno3D Logo

NVIDIA's latest card on the graphics market right now is the GeForce GTX 275. Like all other GTX 2xx cards it is based on NVIDIA's GT200 GPU. While it doesn't bring anything new technology wise. It still has interesting specs: It is basically half a GTX 295 running at 633 / 1134 / 1404 MHz (core/memory/shader). You can see it as a GeForce GTX 285 with a 448-bit memory interface, or you could see it as a GTX 260 with 240 shaders and higher clocks.

For their GeForce GTX 275 OC, Inno3D went with a P897 based design and simply increased the core, shader and memory clocks.

Packaging & Contents

Package Front
Package Back

Inno3D's package uses metal highlights and a pretty lady to catch your attention. All the important product highlights can be found on the front of the package. The design looks a bit too "stickery" to me, but works very well.

You will receive:
  • Graphics card
  • Documentation + Driver CD
  • DVI Adapter + HDMI Adapter
  • PCI-Express power cable
  • TV out cables
  • Warmonger full game + Company of Heroes full game
  • NVIDIA 20% off Mirror's Edge coupon
  • SPDIF audio cable

The Card

Graphics Card Front
Graphics Card Back
Graphics Card Height

Apart from the sticker the card looks like any other GTX 260 / 280 card. It uses two cooling slots as expected. Unlike the Zotac GTX 275, the Inno3D GeForce GTX 275 uses a green PCB.

Monitor Outputs, Display Connectors

The card has two DVI ports, the most common output configuration today. If you want to use the card with your big TV screen you can use the included HDMI adapter. In case you need an analog port you can also use the included DVI adapter.
For HDMI Audio, NVIDIA requires you to feed an external audio source, for example from your motherboard's on-board audio, to the card via SPDIF cable. AMD on the other hand has integrated a sound device inside their GPUs which is the easier solution for most users.
The gold plated connectors are a nice touch but do not actually improve signal quality or anything.

You may combine two or three GTX 275 cards in SLI for improved performance or better image quality.

Here are the front and the back of the card, high-res versions are also available (front, back). If you choose to use these images for voltmods etc, please include a link back to this site or let us post your article.

A Closer Look

Graphics Card Cooler Front
Graphics Card Cooler Back

The cooler of the GTX 275 is identical to that on the GTX 285 or 55 nm GTX 260.

Graphics Card Power Plugs

Two six pin power connectors are present on the card. Both are required for operation of the card. Further to the right in the picture you can see the white input for SPDIF audio.

Graphics Card Memory Chips

The GDDR3 memory chips are made by Hynix and carry the model number H5RS5223CFR-N2C. With a cycle time of 0.8 ns, they are specified to run at 1200 MHz.

The ADP4100 voltage controller has been spotted first on the NVIDIA P897 design for the GTX 260. It does not support the I2C interface which means software voltage control will be almost impossible to implement.

Graphics Chip GPU

The GPU is the NVIDIA GT200b, which is made in a 55 nm process with 1.4 billion transistors.
