I remember when Sony used to care about gamers and take big losses on all their consoles. Sad to see this.

HD 7850's chip size already smaller than 1st gen NVIDIA RSX.
---
1st gen NVIDIA RSX = 258 mm^2
1st gen IBM CELL = 230 mm^2
Total chip size: 488 mm^2

Semi-custom AMD Jaguar with 8 cores with Radeon HD 7850
AMD Jaguar CPU cores: 3.1 mm^2 + 2.1 mm^2 L2 cache = 5.2 mm^2 x 8 cores = 41.6 mm^2 (28nm process tech)
AMD Radeon HD 7850 (16 CU GpGPU) = 212 mm^2 (28nm process tech)
Total chip size: 253.6 mm^2
AMD Trinity APU's chip size is 228mm^2 (with 32nm process tech) i.e. AMD Piledriver (designed by AMD's green team) is not efficient with transistor density.

On transistors packing skills...
With 28nm process tech, AMD Radeon HD 7870 has a chip size of 212 mm^2 (packing 2.8 billion transistors) and delivers 2560 GFLOPS. Density of 13.2 billion transistors per mm^2.
Based on CELL's 115 mm^2 @ 45 nm process tech, 28 nm version of CELL would have a chip size of 71 mm^2. Density of ~3.34 million transistors per mm^2.
With 45 nm process tech, IBM Power 7, has a chip size of 567 mm^2 (packing 1.2 billion transistors). Density of ~2.12 million transistors per mm^2
With 28 nm process tech, IBM Power 7, has a chip size of 352.8 mm^2 (packing 1.2 billion transistors). Density of ~3.40 million transistors per mm^2
IBM is consistent with inferior transistors per mm^2 skills.
