The Palit GTX 260 Sonic is a card designed for the enthusiast and comes pre overclocked from the manufacturer. Clock speeds have been increased on the GPU (576MHz to 625MHz), shader processors (1242MHz to 1348MHZ) and the memory (1000MHz to 1100MHz). To combat the additional heat generated by the increase in clock speeds, Sonic uses a custom cooling solution that uses two fans and a three heatpipe based heatsink to cool down the 55nm GT200 core and board components. The Sonic GTX 260 is for use in a PCI-E x16 slot and will take up at least two expansion slots.
The front end of the card contains all of the connectivity options for the GTX 260 Sonic. What we have is pretty much standard fare with the two Dual Link DVI outputs as well as the HDTV output. The rear of the GTX 260 Sonic is open, allowing the heat generated by the core to be exhausted and to help cool the power regulation circuits.
Along the top side of the the GTX 260 Sonic are the SLI Bridge connections. This card, just like all GTX 260s, is Tri SLI capable. Power is supplied via two 6-pin PCI-E power connections. Nex to the power supply you have a small 2-pin connection that is the S/PDIF sound input connection point so that you can deliver sound through the HDMI connection.
The Palit GTX 260 216 SP Sonic is the first custom designed video card to make use of a dual fan cooling setup. The two fans used to cool the heatpipe based heatsink are interconnected PWM fans. The fans can be thermally controlled as well as manually controlled. When at 100% the fans create some noise but nothing that is objectionable. The heatsink makes use of three heatpipes to discharge the heat from the GT200 core.
The GTX 260 216SP Sonic is built upon a 55nm GT200 core with 896MB of Samsung .8ns GDDR3 memory running through a 448 bit bus. Since the GTX 260 216SP Sonic is a pre overclocked card, the clock speeds have been increased from the stock 576MHz to 625MHz, the shader processor clocks went from 1242MHz to 1348MHz, and with the memory scaling from 1000MHz to 1100MHz. All pretty big jumps from the stock numbers.
Let's get this monster installed and see what it can do. Custom cooled and pre overclocked should be a recipe for excellent performance.
