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
Radeon HD 7850
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.
The HD 7950 has 2048 SPUs, 128 TAUs and 32 ROPs. The only other ports are on the I/O panel where you'll find a dual DL-DVI connector, a single HDMI 1.4a port, and two mini-DisplayPort 1.2 sockets. Supports a max resolution of 2560x1600 on up to 3 monitors.

The AMD ATI Radeon HD 7970 measures 27 cm long (10.6 in), the GPU core is clocked at 925MHz, and the GDDR5 memory operates at the same frequency of 1375MHz (5.5GHz DDR). Still, pairing that frequency with a 384-bit memory bus gives the HD 7970 264GB/s of theoretical bandwidth. The HD 7970 carries 2048 SPUs, 128 TAUs and 32 ROPs, up 33% from 1536 SPUs and 96 TAUs, it's also the first PCI Express 3.0-compatible card.
