has there been a cpu without pins?

[Lilninjsways]

has there been one? if not why pins? also on the motherboard what's all the prickly stuff on the back of it? sometimes front (I'm new to building pc's and only know about how fast stuff runs and what's compatible with what and also how to build) I dont know any thing about the small stuff like that

[The Sloth]

just a short answer data transfer, CPUs are made of things called transistor that executes instructions, pins are the fastest way to interface with a mobo. 

[RadiatingLight]

Well intel CPUs don't have pins (although intel sockets do)

 

pins are needed to have electrical contact.

pads on both sides would suck, because then the CPU would need to be perfectly flat to work, and it simply wouldn't be good.

 

the stuff on the back is solder points. just sharp and annoying, nothing inherently electrical about them. simply points where stuff is connected to the board.

(you can smooth down the sharp bits if you want and it won't kill the board AFAIK)

intel and amd both have pins, intel has pins in mobo amd has pins on cpu.

look in your mobo cpu socket 

[2FA]

It's called Ball Grid Array (BGA). Instead of pins, solder balls are used to connect the CPU to the mainboard.

[ProjectBox153]

The pins for Intel CPUs nowadays are on the socket itself. As to the "prickly" stuff on the underside of the motherboard, those are the solder joints for various components of the board.

Lol. I am not stupid, the pins are in the socket, but the CPU doesn't have pins

those are called cpu pins 

[KeemoSabe]

To cut the story short, data transfer need pins whether on the CPU (AMD) or on the socket (Intel). You won't need to worry about the solder joints at the back as long as you don't short them out. LOL. 

 

Some motherboards and GPUs have backplates to protect the PCB, not really necessary, but if you have the money get one. It contributes to aesthetics too!

Not on the CPU, but in the socket.

to interface with the cpu, that's why its called cpu pins.

Yes, but they are not on the cpu

nvm, not even gonna try, here a video, i haven't watched but this should help

That still aren't on the CPU. Yes we get your argument. It's true the CPU pins are in the motherboard, but the CPU itself doesn't come with pins, they are not in the box that contains your CPU when you buy it. If you don't purchase a motherboard to accommodate an Intel CPU that you purchased then you're an idiot (you also have a processor that doesn't have CPU pins). Therefore Intel CPUs do not have pins... Intel based motherboards do.

its better to understand a topic before launching personal attacks, let's make that cpu work without pins, OP was asking about functionality of the pins so on amd side the cpu has pins, intel side mobo has pins, you can't make a cpu work without them. i was pointing out no cpu currently on intel or amd side works without use of pins.

I didn't mean you were an idiot. I was referring to some arbitrary person that decides to purchase a CPU without a motherboard to support said CPU. That kind of person would be the idiot, not you. I edited the original post to reflect that because I noticed it could be read in a way that I did not intend.

Sorry to resurrect this old thread, but nobody fully addressed OPs question, so my forum OCD forced me to go as far as to create an account in LTT just to answer this... so here it goes. Both Intel and AMD DID sell a CPU with no pins.. Those CPUs had golden fingers, the same as a PCIe card, and they were installed in a slot in the mobo. For Intel, it was called "Slot 1", and for AMD it was called "Slot A". But that was not the best approach because the electricity between the CPU inernal circuitry and the mobo had to travel a longer distance, meaning slower performance... that is why the went back to sickets on the mobo, and as close as they can be to memory slots, to have better performance.

 

Now I think my forum OCD can go to sleep... and so this thread (hits zombie thread with a shovel).

LGA = land grid array, pins in socket

PGA = Pin Grid Array, pins on cpu

BGA = Ball grid array, soldered cpu to board.

 

Also in the way distant past, slotted socket cpus such as slot 1 and slot A. Just like a ram stick only bigger

[solarflare]

In early 2000's Some Intel and AMD cpu's were on cards that slotted in like PCI-E slots... it didn't work that well and it was hard to put a heatsink on it. 

I know lots AMD's that died in the slot era from heat. 

[Mister Woof]

Had two of these, an Intel Premium III 450mhz and an AMD Athlon 1000mhz

Woah, I don't even remember making this thread!! Well thank you guys so much! For the replies

Lol yeah a little necro. I didnt realize it till after I had posted
