Both the Component cables & HDMI cable CAN display 1080i-(Interlaced) & 1080p-(Progressive Scan), the difference is that the Component cable is an Analog cable, whether you're using 1080i or 1080p the signal WILL be Analog, the HDMI cable is a Digital cable, whether you're using 1080i 0r 1080p, the signal WILL be Digital. The HDMI cable would display the higher quality picture, because it's Digital & not Analog, the difference in picture quality may not be the significant when comparing a Component hook-up in 1080p to an HDMI hook-up in 1080p, but there WILL be a difference, because even if the resolution is the same & both signals are in Progressive Scan, the Digital signal that the HDMI cable delivers is a higher quality signal than the Analog signal that the Component cable delivers. In the end, both Component cables & HDMI cables are an excellent hook-up for picture quality, Component is the best Analog signal you can use, & HDMI is the best Digital signal you can use, but long story short, the HDMI cable WILL give the higher picture quality because it's Digital, & Digital is higher quality than Analog.

These cables will work with the PS2, the PS3, & even the original PS1, all PS systems use the same Audio/Video output adapter.
