  So far the most reasonable explanation I've seen by googling is someone if a forum suggesting that its function is just disabling certain features so as to prioritize smooth playback over those features. I don't see any difference with the 5770, otherwise (with that card it doesn't disable anything).

  I sort of assumed it was similar to what 120hz/240hz LCD TVs do: use a frame doubler to more closely match your monitor's refresh rate and give the impression of "smooth" motion.

  I don't think so, most PC displays are 60 Hz, and I think even most 120 Hz TVs only take up to 60p input. There's only a couple of 120Hz-input monitors.

  Actually, most CRTs using analog connections are capable of 120Hz. DVI, HDMI, and DisplayPort do not support digital transmission speeds over 60Hz. It's a sad state of affairs if you ask me.

  I know this isn't exactly supposed to be a fast card, but its clocked ~10% faster yet its slower than the last generation card... I can't say I am surprised though, after seeing the 5770 clocked faster than the 4870 yet being around the same speed.

  I think people are missing allot of the big picture here and that's Crossfire with the Radeon 54xx series.
  Specifically with the new 8 series of chipsets, hence the amount of shaders present, I expect a return of Hybrid Crossfire.
  
  Pairing an IGP with a low-end card is a very cost effective solution to getting more performance out of a system and also gives AMD an edge in getting more people to buy an AMD Processor+Chipset+Graphics card.

  "me too" I'd dig a 758G Hybrid Crossfire review with this and the other sub $100 Radeons (if they support x-fire) 785 was a great motherboard to match with the Athlon II and Phenom II X2-X3, some of us were waiting on video card purchases and would like to see Crossfire 54XX/56XX compared to a 5750 discrete for example.

  Fun fact: HD 5450 is about 40% faster than my pathetic old 7600 GT in my work PC. Remember when 6600 GT was da bomb? LOL

  The 80 shader discrete Radeons are just too limited by 64-bit DDR3. The 785G has more bandwidth and the same number of ROPS (mine even runs fine at 1GHz.) If they had cut the power usage of the 5450 down a lot more it may have made some sense.

  5770 128-bit bus, 4870 256-bit bus
  
  again 5450 64-bit bus, 4550 128-bit bus
