Today we shall review a couple of card from Palit: a GeForce GTX 570 from the Sonic Platinum series, which is quite similar to counterparts from Gainward and Zotac, and a GeForce GTX 580 with as many as 3GB of video memory.

Specifications

Speaking of Palit GeForce GTX 570 Sonic Platinum 1280MB GDDR5, the only thing that reminds of the reference design is the layout of memory chips. The rest has been overhauled: from output connectors to the improved power supply unit for higher clock rates. Besides, the card has one 6-pin and one 8-pin supplementary power connectors, like GeForce GTX 580.

Palit GeForce GTX 580 3072MB GDDR5 has also been customized in a similar way, so the card has non-standard output connectors and a better power supply unit for higher-frequency memory chips.

Maximum resolutions and frequencies:

• 240 Hz maximum refresh rate
• 2560 x 1600 @ 60Hz max. digital (DVI) resolution
• 2048 x 1536 @ 85Hz max. analog (VGA) resolution

Each card has one 6-pin and one 8-pin supplementary power connector.
