Underside of AMD Ryzen Threadripper Pictured

[btarunr]

AMD Ryzen Threadripper is a really big processor, and here's what its underside looks like. A multi-chip module (MCM) of two eight-core "Summit Ridge" dies, it is also AMD's first client-segment processor to feature a land-grid array (LGA) socket interface, since the decade-old Athlon64 FX 72; with the pins being located on the motherboard, and contact-points on the CPU package. Until now, AMD has limited large LGA sockets to its enterprise processors. The processor is based on the 4,094-pin socket SP3r2, which is increasingly being referred to by motherboard and cooler manufacturers as "TR4."

Given that it is an MCM of two dies, you can see a clear dividing line between two groups of the contact points that make up the total pin count of 4,094 pins. There are also two distinct ancillary cutouts which holds critical electrical components for the dies above. Something like this is lacking on the socket AM4 Ryzen "Summit Ridge" processors, where the cutout is blank, and the ancillaries are located around the CPU die, on the other side of the fiberglass substrate. AMD Ryzen Threadripper could be available from 27 July.

Fx 70/72/74 are the first "client grade" cpus amd delivered in LGA.

Even the socket is unusual for these CPUs, I think this is the first time I have seen a allen key used to install/remove CPU from socket.

This thing is huge.

That's a big gray area, IMO. Since you still needed a workstation board to use those processors, so I'd actually say they were still workstation CPUs, not client class.

Cpu itself was not targeted at workstation users though... Big Gray area. Those definitely client chips.

Keep this up and the CPU will be bigger than the Motherboard eventually

Bigger cooling surface - better cooling

How could I forget that. Thanks, updated.

My first thought was, "oh, just slap one chip of HBM2 memory and a LCD on it and we'll have a nice AIO PC"

2 dies, 2 CPU coolers...

That what she said

 

[uuuaaaaaa]

This platform looks glorious!

AMDs thinks to them self..... now pins on CPU or MB umm bent pins on a $300 part or bent pins on a $800 part..... we better change our crappy design this time around.

It makes a lot more sense when the cost of the CPU starts to go above the cost of the motherboard. What would you rather replace? A $300 CPU or a $150 motherboard? Then consider a more expensive CPU on a newer platform where your options are a $800 CPU or a $300 motherboard? I personally like LGA because I think it's a better method of holding the CPU in place by clamping it down as opposed to relying on the clamping down on the pins themselves which puts stress on the pins and contacts rather than the heatspreader.

Its huge!!!!! Lol! What existing cooler fits that?!!!!

Laptops use a key to lock in the cpu.

When that day comes, we'll also be using microSD cards for L1/L2/L3 cache expansion.

Lol my point, LGA should be a standard by now but AMD still wants to use crap intel used for Pentium 1.

Biggest issue with LGA is the contact surface and how much power it can handle as pins get smaller, in a compressed pin and socket arrangement the contact area is much higher VS pins touching a surface.

...wheres the pic of the amd exec making fun of kentsfield because it was two cpus slapped on the same die?

this looks like two cpus slapped together...

 

[cdawall]

Possibly the noctua ones aimed at G34 if so that is awesome I already have two air coolers and two waterblocks

 

[jasonelmore]

yeah LGA has it's downsides. It' cant draw as much current per node as AMD's old PIN System could.. Your going from a 3 Dimensional contact, to a 2d contact.
