Introduction
The NVIDIA GTX 260 has been on the market for quite a while. It was followed by the GTX 260 with 216 shaders to combat ATI's offerings at that time. Now NVIDIA has given permission to their add in board partners to create custom PCB and cooling designs to further diversify their product range.
Palit's GTX 260 Sonic comes in the 216 shader flavor with higher clock speeds out of the box. The cooling system has also been completely revamped to employ Palit's Revolution cooler, yet still uses two slots in your motherboard. What is very uncommon for NVIDIA graphics card is the PCB color which can only be described as ATI red - yes it still looks good. Not only the PCB color has been changed, but large sections of the PCB layout have also been customized, most probably to reduce cost.

Packaging & Contents
Palit has chosen to use a green box with their famous Palit Frog on it. The front of the package clearly communicates all the important specs: the card is a GTX 260, with 216 shaders, 896 MB of memory and clock speeds of 625/1100. Excellent job. On the back you find additional product detail in multiple languages.
You will receive:
- Graphics card
- Documentation + Driver CD
- PCI-E Power Cable
- SPDIF audio cable
- DVI Adapter + HDMI Adapter
- TV Out cables
The Card
Palit's cooling system uses a dual-fan cooler that seems to be a custom design for Palit. As mentioned before, the card uses two cooling slots in your system.
The card has two DVI ports, which is the standard output configuration nowadays. In case you need an analog VGA output, you can use a DVI adapter (included). In case you want to connect your big digital TV screen, you can use the included HDMI adapter. The HDCP output features the usual HDCP+Audio, which allows easy setup of a media PC. 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 (also included). AMD on the other hand has integrated a sound device inside their GPUs which is the easier solution for most users.
Here are the front and the back of the cards, high-res versions are also available (

A Closer Look
The cooling assembly is made of several parts. First you remove the plastic top cooler which houses the dual fans. Please note here that both fans are connected to the same cable which means they are both temperature controlled but always running at the same speed.
Directly below the fans you will find a large heatpipe based heatsink module. It uses three heatpipes and a large number of fins to move heat away from the GPU quickly, no other components are cooled by that part of the cooling system. Further to the back you will find a small black heatsink that is responsible for cooling the power regulation circuitry.
Once the heatpipe heatsink is removed, another piece of metal can be found on the rest of the card. It overs all the other components that need some form of cooling, like the memory chips, the NVIO chip and the memory voltage regulators.
You may combine two or more of these cards to build an SLI rig for even higher performance or image quality settings.
The card has two six-pin power connectors, both are required for operation of the card. Further to the right on the picture is the white input for the SPDIF audio to be streamed into the HDMI output.
The GDDR3 memory chips are made by Samsung and carry the model number K4J52324QH-HJ08. With a latency of 0.8 ns, they are specified to run at 1250 MHz.
Unlike the NVIDIA reference design which uses a Volterra voltage regulator, Palit has chosen to go with a Realtek design which is probably a lot cheaper. Unfortunately this means that there is no software voltage control possible because the controller chip has no I2C interface which is required for communication with the host PC.
NVIDIA has separated the display output logic from the GPU on the latest chips. So in order to drive the display outputs the NVIO chip is required.
Here you can see the GT200b GPU that powers the GTX 260. It is made in a 55 nm process with 1.4 billion transistors.
