March 5, 2012, By Sanjeev Ramachandran

AMD has finished polishing the new chips from their stable and Radeon HD 7850 and 7870 GHz edition are active now. Belonging to the Radeon HD 7000 series, two of those chips will go to the mid-range segment of the gaming market.

The new Radeon HD 7850 stuffs a 2 GB RAM and runs at 860 MHz core. It has a 1024 visual effects stream core and 64 texture units while sporting a 256-bit memory bus.

It packs in 4.8 Gbps GDDR5 memory too.  On the power consumption front, 7850 stands at 150 W peak and uses PowerTune to manage power consumption when left idle.

7870 GHz Edition is stronger with 1280 stream cores and 80 texture units while having the same 256 bit memory bus and 4.8 Gbps GDDR5 memory like Radeon HD 7850.

It offers greater processing than the 7850 chip with its 1 GHz core speed. 7870 is at the peak when it comes to power consumption with 190 W,  however, makes use of Power Tune like its bro when idle.

Both these chips have many things in common. Both have Direct X 11.1 and 64-bit floating point support. They also have OpenGL 4 visual effects and high speed HDMI and mini DisplayPort.

However, both these chips come more expensive than their NVIDIA rivals. 7850 will come at $250 which is more than that of GeForce GTX 560 Ti. 7870 costs $350 which makes it pricier than the GTX 570 from NVIDIA.

Boards equipped with these chips are expected to surface in two weeks time.
