You calculation looks complicated, it's not required. As for the 3.9W 3dmark Temash we have an official score from AMD:

Test conducted in AMD Performance Labs using FutureMark 3DMark for Windows 8 Ice Storm Test as a metric for GPU performance. The AMD A4-1200 APU-based system scored 11,920 while the Intel Atom Z2760 based system scored 2431. The platforms tested were the “Larne” reference platform with an AMD A4-1200 Dual Core 1.0GHz APU, AMD Radeon™ HD 8180 series graphics, 2GB DDR3-1066 system memory and Microsoft Windows 8, versus an Acer ICONIA W510-1666 with an Intel Atom Z2760 1.5GHz CPU, Intel integrated graphics, 2GB DDR3-1066 system memory and Microsoft Windows 8.

It scores 11,920.....we can round it to 12k. We already know that Z2760 scores 2400-2500 in 3dmark Ice storm. For the Z3770 Bay Trail-T we have this: http://files.shareholder.com/downloads/INTC/2455550139x0x668715/24d82a6d-9b7c-4dad-b7bf-802ba9b220d3/Hermann_Eul_Computex_2013_keynote.pdf

4.7x of Asus Vivo Tab. Asus Vivo Tab with the Z2760 scores 2456 in this test: http://www.computerbase.de/artikel/tablets/2013/test-acer-iconia-w510/3/

2456x4,7= 11,543

In 3dmark Ice Storm Z3770 Bay Trail-T seems to match almost the 3.9W Temash score. However I think the much better CPU in Bay Trail-T helps a bit in 3dmark Ice Storm.
