There has been much speculation on what exactly was the difference between the RK2728 chip and rockchips new generation chip, the RK2806, i think i have my answer now. Simply put the RK2728 chip is made to used in players that were designed around the RK2706 chip, factories only need to change the chip, without changing any other hardware and load up a newer fimrware.

This really isn’t anything new, this pretty much was the same for players using the older RK2608 chip that then started using the RK2706 chip. It didn’t happen with the RK2806 chip as this required different additional hardware to be present for it to properly work (in particular more SDRAM), i guess it just took Rockchip a little longer to develop a chip capable of doing the same as the RK2806 but based around the RK2706 architecture.

I think only a hands on test will really confirm if the RK2728 chip is as good as the RK2806 chip.

Don’t expect the VX777R to be the last to have the upgrade, i suspect we will soon see a lot of older players under going the same upgrade.
