As first noted in a leaked roadmap last month and now seemingly confirmed by Chinese website EXPreview.com, AMD is scheduled to release their mid-range HD 7870 and 7850 series graphics cards based on the Pitcairn GPU in March. The latest leak reveals one Radeon HD 7870 and two Radeon HD 7850 cards; one with 1GB of memory and the other featuring 2GB.  

Specifications for each card can be found below.

Radeon HD 7870

  • 22 Graphics CoreNext Compute Units
  • 1408 stream processors
  • 88 TMUs
  • 24 ROPs
  • Memory bus of 256-bit
  • Memory size of 2GB GDDR5 memory
  • Clock speeds of 950 MHz core
  • Memory frequency of 1375 MHz (5.50 GHz effective)

Radeon HD 7850

  • 20 Graphics CoreNext Compute Units
  • 1280 stream processors
  • 80 TMUs
  • 24 ROPs
  • Memory Bus of 256-bit
  • Memory size of 1 GB/2GB GDDR5 memory
  • Clock speeds of 900 MHz core
  • Memory frequency of 1250 MHz (5.00 GHz effective)

According to Tom's Hardware, early pricing for the HD 7870 is in the $300 ballpark while HD 7850 cards are expected to start around $220. It’s of course worth mentioning that these specifications aren’t official and even if they prove to be accurate, they only cover reference cards so we are likely to see manufacturers squeeze a bit more performance out of each via overclocking. We’ll likely know more come March 6 when CeBIT kicks off in Hanover, Germany.
