Computex 2009: AMD Demonstrates working 40nm DirectX 11 Silicon

[Shintai]

there are no 55nm HD 4000 GPU with 640 SPs, 32 TMUs, 16 ROPs and 128bit mem BUS!

so you're wrong! RV740 is NOT shrink of any other GPU from AMD!

And that would make RV740 shaders, memory controller, TMU, ROP etc different how? And I didnt say it was a shrinked existing GPU. RV740 is just a shrink of the existing design without changes.
