AMD Radeon HD 4000 Series Review Roundup

• Bjorn3D: Sapphire HD4870 Toxic:
  
  

  "While the GTX-260 turned in better numbers in basically everything we put it through, during gaming we couldn't tell the difference between it and the Sapphire HD 4870 Toxic except of one or two exceptions when the Toxic tossed in a little stutter every now and then. The Sapphire HD 4870 Toxic made us just as happy as any of the other tested GPU's in gaming and surfing. When it comes to video cards, synthetic benchmarks are good for comparison, but living and gaming with a GPU is really where you want satisfaction."

• Metku: ATI HD4850 Roundup with non-reference cards:
  
  

  "All of the HD4850 cards showed great performance and some promising overclocking results. The cooling also had been improved from the reference design, in all of the four cards that we had in our review. This way the cards are both quieter and cooler than they would have been with the reference cooler. These four cards have also been heavily overclocked, making these considerably faster than the reference cards."

• Modders-Inc: Sapphire Radeon HD4650 OC Edition 512mb GDDR3:
  
  

  "In short this card isn't for everyone. As with all purchases be sure you really consider what your needs are now and what you think they might be in 6 months. This little card has some kick for the price and if you are in the market for a card and you've got a budget I would definitely put this on your list of cards to consider. If you are casual gamer, an HTPC user, or even looking to upgrade your existing system, this card is a pretty sweet card."

• Modders-Inc: Sapphire Radeon HD 4550:
  
  

  "Folks, the $59.99 Sapphire HD4550 is, quite simply, a great card. You have to buy the card under the proper technical reasons (low power consumption, 1/2 height video solution, cool running, excellent HTPC performance on playback, HDMI and HDCP compliance) and not because you are wanting to play Bioshock/Farcry2/Crysis at the highest framerates.
  
  This card excells at the market it is aimed squarely at, and I will unequivicably recommend this card for people who have gaming performance 2nd or 3rd down the list, and HTPC needs in the front. "

• PCSTATS: Asus EAH4850 HTDI/512M/A Radeon HD 4850 Videocard:
  
  

  "Ultimately the Asus EAH4850 is an economical videocard with moderate overclocking capability for the gamer who wants to play the newest games at reasonable resolutions. There's not quite enough OC head room in it to turn it into a Radeon HD 4870 X2... but enough of a boost for a noticeable improvement when running Crysis at max image quality settings. Again, midrange videocards like the Radeon HD 4850 tend to be pretty good overclockers, usually sharing the same architecture as the high-end cards in the same family, but with lowered clock & memory speeds.

• PureOverclock: Sapphire Radeon 4870 X2:
  
  

  "Boasting stunning performance and excellent features in a sleek package, the Sapphire Radeon 4870 X2 is king of the hill for now, easily chewing through modern games for those consumers with higher-resolution monitors, high expectations, and high budgets."

• XSReviews: Sapphire HD 4830 512MB Review:
  
  

  "The HD 4830 from Sapphire is a damn nice card for the money. It might not be the quietest one out there, but it's only slightly behind the 4850 on the performance scale, and with it's great overclocking ability, and don't forget you can always add a second, therefore running two of these bad boys, for around 2/3 of the cost of a GTX 280.
  
  While there seems little reason to have the 4850, and the 4830, apart from the fact that those without that extra £20 will have a card to buy the 4830 did very well in our testing. So if you're looking for a new card around £100, then get the 4830, or if you have £120, get the 4550. There 'aint a lot of difference."
