Core i7-920 in 1366-land LGA package, and Core i7-870 in 1156-land LGA package processors side by side. The I7-870 is about the same size as socket 775 processors. Contact pads on the back of the 870 are located closer to each other than contact pads on LGA775 processors. The contact pads on the I7-870 are shaped the same way as on the I7-9xx processors.
