The first thing anyone should notice about this card is that its cooler is far from the reference design. Just like the reference NVIDIA GTX 570, the Palit GTX 570 Sonic Platinum is only 10.5" in length and still uses a dual-slot cooler. However, that is where the similarities end. The card features a completely silver design with black and gray decals. Right in the center of the card are two very quiet fans from Power Logic. Each fan is rated at 3500RPM and only 37.65dB. To the left of the fans is a decal with Palit's logo. To the right is another decal with the GTX 570 decal.
As far as connectivity goes, you'll have a bit more than the reference design. You'll be given the standard two DVI ports, an HDMI port, and a DisplayPort. Powering this card is as simple as using two 6-pin connectors. Just as with the reference design, the Palit GTX 570 has a TDP of 219 watts, and the recommended power supply is a mere 550W unit.
The Palit GTX 570 Sonic Platinum once again follows the NVIDIA reference design in that it is equipped with two SLI connectors. This means, if you've got the cash, you'll be able to pair this baby with up to two more GTX 570s for an easy performance boost. The Palit GTX 570 Sonic Platinum also uses the very friendly PCIe x16 2.0 interface.
Pulling the cooler off the card shows us how different the "Mercury Design" cooler is from the reference cooler. Unlike the reference card, the Palit GTX 570 Sonic Platinum's massive heatsink is built into the fan shroud. The GF110 core comes directly into contact with the cooler's copper base. You may also notice that each of the card's fans have their own power connectors. This is nice to see considering that other dual-fan coolers will use one power connector between the two fans. Palit didn't forget about the rest of the card's components either — taking a look at the cooler's bottom reveals heatspreaders for each of the GTX 570 Sonic Platinum's important components.
Taking apart this card's cooler was a bit trickier than other cards I've encountered. In fact, removing the cooler was also more difficult than past GPUs. However, it is possible, and once taken apart, the large-finned cooler does nothing less than impress. What appears to be a giant finned array of aluminum spans almost the entire length of the card. Spread fairly evenly amongst these fans are four copper heatpipes, which should help the cooler to dissipate a massive amount of heat. Flipping the cooler over reveals a nice and smooth copper contact for the GF110 core. After seeing just how large this cooler actually is, I have no doubts that it will allow the Palit GTX 570 Sonic Platinum to run cooler than your average GTX 570.
Finally, we've got the 40nm GF110 core. This baby is packed full of 480 cores, 60 texture units, and 40 ROPS. Not only that, but the Palit GTX 570 Sonic Platinum's core has been overclocked to 800MHz with a shader clock of 1600MHz. Located around the core, we can see the very familiar Samsung memory modules. This 1280MB of GDDR5 memory is on a 320-bit bus and comes factory overclocked at 4000MHz.
Now that we've got up close and personal with the card, let's take a look at how it performs.
