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

GCN Architecture
16 Compute Units (1024 Stream Processors)
64 Texture Units
128 Z/Stencil ROP Units
32 Color ROP Units
Dual Geometry Engines
Dual Asynchronous Compute Engines (ACE)

Full HD 7950 specs: http://www.amd.com/us/products/desktop/graphics/7000/7950/Pages/radeon-7950.aspx#3

GCN Architecture
28 Compute Units (1792 Stream Processors)
112 Texture Units
128 Z/Stencil ROP Units
32 Color ROP Units
Dual geometry units

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  :(
