Gigabyte and Palit GeForce 9800 GT Face Off
Adding to this confusion, however, are cards like the GeForce 9800 GT. Unlike the prevailing theory that higher numbers mean newer / better performing products, the 9800 GT is actually little more than a rebranded 8800 GT with support for HDMI audio output and HybridPower. HDMI audio output is achieved using a secondary audio cable, like the current cards in the GTX 200 series. And HybridPower is an interesting feature in which your video card is turned off when not needed in favor of a low-power IGP, but it requires a compatible motherboard and for now they only come AMD-flavored. Currently 9800 GT and 8800 GT cards share the same 65nm GPU, but rumor has it a 55nm version will be arriving soon. What that means in terms of clock frequencies and power consumption remains to be seen, but for now most 9800 GT and 8800 GT cards share similar GPU and memory clocks...
