How come AMD hasn't switched to LGA for their desktop chips?

post #1 of 5
Thread Starter 
I know they've done it for their opteron chips, but why not on their desktop chips?

LGA has a lot of benefits..

- It offloads the responsibility of pin related RMAs to the motherboard manufacturer
- It's a more flexible design. LGA chips can be soldered onto a motherboard (not relevant for builders, but it allows OEMs more options with how to use the chips)
- It's better for builders IMO, since I think you're less likely to screw up with LGA then with the pins on the chip. And if people do anything crazy like lap/delid the chip it's easier w/ LGA (though to the makers, this is pretty much irrelevant since those people account for maybe 1 out of a million CPU sales)
- LGA chips are fastened much more securely to the motherboard. Once that loading plate is down it's not coming out. People pulling a chip out of the mobo (and possibly ruining it) when it's stuck to the heat sink is fairly common when the pins are on the CPU. Not an issue with LGA.

Biggest reason is probably socket compatibility. AMD has always had long life times on there sockets as well as backwards compatibility.

If AMD is to move to a LGA type socket it wont happen before DDR4 (and AMD's next gen socket).

Haven t you heard the problems with the Intel Foxconn sockets that were catching fire.
The AMD pin stuff is ok ,nothing wrong with it.
Easy to install.

You have no idea how hard is in some countries to get RMA for a mobo with a bent pin.So many have been left with no warranty from retailers for a bent mobo pin.
Never happened to me to bend a pin on the AMD-s so if you know how to manuver the CPU it s perfectly safe.

Gets the job done.

Opterons use that approach so AMD uses it where they consider necessary.

I can't see them doing this. almost EVER.

in changing the socket to LGA, the processors themselves would have to be changed to be able to use both AMD and intel chipsets.

this would be a RMA nightmare for the company. getting countless RMA's because the chip sets don't work the same would be rather labour intensive for them.

only thing i can see is AMD, cornering the EoL market, with modified FX or trinity chips in the LGA format (1366, 1156 and 1155?) to be able to work cohesively those those generations intel chip sets.

that would effectively be two birds with one stone. if not a whole flock with one stone...

Giving consumers an option other then full out replacement upgrade.(basically a jump ship clause... Intel wants your big moneys and your first born, while amd just wants a hug.)

increased sales revenue

would not alienate those who supported AMD in all previous sockets.

would give AMD a unique opportunity, to backwards engineer some of the LGA intel stuff.(basically more ideas for the future etc)

Who said anything about changing the socket to an intel socket?

They would use their own LGA socket, just like they did with server chips, which are not compatible with intel server motherboards.
