[edit]Electrical contacts on bottom of Intel Core CPU
[edit]
On the bottom of an Intel Core CPU, are all of these things electrical contacts or only ones inside the smaller rectangle? Bubba73 You talkin' to me? 01:05, 24 December 2017 (UTC)
- LGA 1155 seems to say that the things outside the smaller rectangle are the electrical contacts. Bubba73 You talkin' to me? 01:22, 24 December 2017 (UTC)
- The stuff in the middle are SMT components. If you look at the socket on the motherboard, it should be obvious where the pins are that make contact with the CPU. Nil Einne (talk) 04:37, 24 December 2017 (UTC)
- A picture of a CPU socket may help clarify things. https://upload.wikimedia.org/wikipedia/commons/thumb/d/d9/SocketA.jpg/1200px-SocketA.jpg Those pins you see on the outside of that CPU enter the little holes you see in the socket. Here is a photo of an old CPU with the pins clearly visible https://en.wikipedia.org/wiki/File:Intel_80486DX2_bottom.jpg (((The Quixotic Potato))) (talk) 06:48, 24 December 2017 (UTC)

- We're talking about modern Intel desktop processors with LGA sockets. The CPUs do not have 'pins' and the sockets do not have 'holes' under most ordinary definitions of those words. As stated, the motherboard socket should have what are generally called pins, although they are of different design than PGA style pins on AMD desktop CPUs and older Intel CPUs. The CPU doesn't really have what would be called holes, but simply pads, so really there are no holes involved in the contacts (unless you refer to the design of the pins).

- Land grid array: Unlike the pin grid array (PGA) interface found on most AMD and older Intel processors, there are no pins on the chip; in place of the pins are pads of bare gold-plated copper that touch protruding pins on the microprocessor's connector on the motherboard.

- Which is what I said. Nil Einne (talk) 16:19, 26 December 2017 (UTC)
- I wasn't disagreeing with you, just providing the relevant text from the Wikipedia article with links for those who want to read more. (((The Quixotic Potato))) (talk) 17:09, 26 December 2017 (UTC)
