Palit has increased its Sonic line-up with the launch of Radeon HD 4870 Sonic Dual Edition video card. This card has several interesting features like Dual-BIOS (where the video card has two BIOS; if the user accidentally damages one of them during overclocking the card will continue working using the other BIOS) and Smart Switch. This Palit card works in two modes: standard mode (core clock of 750 MHz and memory clock of 3,800 MHz DDR) or overclocking mode (core clock of 775 MHz and memory clock of 4,000 MHz DDR). Users can easily switch between standard mode and overclocking mode by pressing a little switch found on video card’s rear panel. Palit Radeon HD 4870 Sonic Dual Edition has 512 MB GDDR5 and uses a cooler featuring three heatpipes and two fans, an 80 mm in charge of cooling the GPU and the memory chips, and other 70 mm in charge of cooling the VRM. No word about price and availability.
