Not a daughter card, but a substrate. Also known as a Multi-chip module (MCM). Intel has done this before with Pentium CPUs. The arrow in the corner is so whoever installs it does it correctly The old Pentium Pro didn't use an arrow, but it had only 3 screw holes, one in each corner forcing you to install it correctly, otherwise the screw holes wouldn't line up. Here's a pic: http://en.wikipedia.org/wiki/File:KL...ve_P6T_Top.jpg Also there is no socket. It's just soldered down in it's designated location. Since other companies will be making motherboards for this, Intel makes it simple by mounting both together on the same substrate. The Wii U also uses 2 chips on the same substrate, designed by IBM, except they went a step further and instead of having a CPU and memory, they put a CPU and GPU together http://www.extremetech.com/gaming/13...ibmamd-cpu-gpu No allignment arrows here, but the allignment holes in each corner are offset from the edge by different amounts forcing the correct orientation.
