That's wrong the HD 7850 (desktop) has 28CU's for 1792 shaders.
The Orbis in this article has
18 Compute Units (CUs) Hardware balanced at 14 CUs
14 CUs for 896 shaders.

There is another HD 7850???
The HD 7950 have 1792 shaders in desktop.
Full HD 7850 specs: http://www.amd.com/us/products/desktop/graphics/7000/7850/Pages/radeon-7850.aspx#3

Please don't make confusion with the names.
The GPU in Orbis have 18 CUs... two more than the HD 7850... if there is 4 dedicaded for others tasks I don't know but the overall raw power is 1.8TF.

My mistake with earlier post
So correction
Tahiti GPU full
7970 32CU's x 64 shaders for 2048 total shaders
Tahiti GPU cut down
7950 28 CU's x 64 shaders for 1792 total shaders
Pitcairn GPU full
7870 20 CU's x 64 shaders for 1280 total shaders
Pitcairn GPU cut down
7850 16 CU's x 64 shaders for 1024 total shaders
Orbis version of Pitcairn GPU
18 CU's or 14 CU's? x 64 shaders = 1152 or 896 total shaders
So it a low-mid range chip unable to get 60 FPS at 1920x1080 in games like Battlefield 3, Crysis 2, Assain Creed 3 or Hitman Absolution.
Great just what we want in a console that won't be replaced till 2020 :(
