Socket A IS PGA I'm told!

[brojoh2]

So I'm talking to the rep @ Newegg about the 1.33ghz cpu I ordered yesterday and I notice the print says "PGA" . . . the rep tells me that's what all Tbirds are (after checking with her super) but I can check it out. Thanx I say, I will.

PGA I say to myself . . . as in FCPGA? WTF?! Wait a minute . . . wait a minute . . . what's going on here? I need to educate myself. So quick as a rabbit - you know I might need to cancel my order or something - I flash over to Tom's - to Axion - hither and yon - to home to ask YOU:

Are all our beloved Socket A Birds PGA? I just didn't know it? Hey I can take it! Just give it to me straight. But please give it to me quick. I got the need to know!

Thanx!

Well they are in the same socekt form (as u know)

But they will not fit in a Intel motherboard if thats what u wanna know, the Intels have 370pins, and the AMD has something like 460.

All modern socket CPUs are PGA: they use a Pin-Grid Array. (Turn your chip upside down. Yep, there is an array of pins protruding from it in a specific grid!)

Of course, Intels and AMDs use different numbers of pins, in different locations, for different purposes.

The most recent chips are FC-PGA: they are Flip-Chip Pin-Grid Array. That means that the die itself is "flipped" and faces upward (and you can see it when looking down at it) instead of facing downward.

If you look at a socket Celeron 1 (not 2) then you will notice that you must turn the chip upside down to see the die. The die is in between the Pin-Grid Array. That is the traditional PPGA arrangement.

Hope this clears things up!
