Intel LGA 3647 First Look

[ahhming]

 

 

Serve the Home posted some pictures of the gigantic LGA 3647 socket.

The upcoming Knights Landing platform will support 6-channel DDR4 support, as well as no dual-latch system that is used on the LGA 2011 platform. Serve the Home explains that the socket and thermal designs that they have seen "do not have latching mechanisms", and instead they're seeing "solutions that secure the CPU to the heat sink".

Unlike the LGA 2011 (V1, V2 and V3 series) system of dual latches, that methodology has been re-designed for LGA 3647. The socket and thermal designs we have seen do not have latching mechanisms. Instead, we are seeing solutions that secure the CPU to the heatsink. Then the entire assembly is guided into place by the socket’s guide pins. Finally screws are used to secure the assembly in place. Here are the screw down instructions for the Supermicro 2U4N solution’s heatsinks that have to deal with well over 200w TDP in a 1U high chassis.

Where the fuck do they get the names for these sockets?

they count the number of pins

via the number of pins on the socket.

Lan grid array(type of connector) then the amount of contacts.

Why don't they just install a big busbar for the power supply +Vss, and Gnd?  Instead of that crazy pin count, most of which are just going to be for power? 

 

Or just ground one side of the case, and have only power pins on the other? 

 

Any electronics gurus here want to speculate?

Its hard to make a good connector for high current. Also its not mostly power.

2000+ pins are either Vss or GND I bet.

Probably less than 1000. Im guessing around 500.

Bring back XL-ATX.  These small form factors are cancer.

Wow...

 

Let's not.

 

Also, why would you want XL-ATX? What CPU are you possibly going to use to supply 9 PCIe slots affordably? Are you going to use a f#ck-ton of RAID or NIC's?

[tsk]

Now let's see linus run two of these in cinebench...

Well, for more ram slots and power delivery...

My opinion: It doesn't make up for the size. You're not gaining much if the chipsets aren't capable of supporting the form factor and added hardware.

[Thony]

Not gonna read the article and OP hasnt mentioned it so I guess its not know atm, what is your guess on core count ? I say 64 !

What do you mean?

If you want 12 ram slots on the board you need EATX, if you want a CPU as big as 3647, you need EATX.

Why do you think that almost all X99 motherboards are EATX?

There's a ton of features and power delivery and all kinds of stuff on the board.

You can even see in the image I posted that there is pretty much 0 free space on the PCB, it's completely packed.

It's because at the cpu scale increasing distance of connections severely degrades signal. Thats why they try to get parts as close together as possible

I understand that. I'm saying why would you want something larger than E-ATX. E-ATX does a mighty fine job of packing features into the space.

And because in the datacenter (where these puppies are going) smaller system means room for more systems.

 

Imagine having knights landing blades that fit 10 of these in a 4-6 u chassis

 

It'll be like a cpu horsepower wet dream.

theres no way these are meant to go in people's personal computers at home

Why not e-atx or ssi eeb. XL-atx isn't a standard and is just bigger than the normal area. Lets use a standard.

Your gotta stuf more than 10 in 4-6U.

 

Your probably thinking around 4-6 per U. Loot at the dell fx chassis with 8x 2011v3 in 1u right now.

True, but on a typical CPU, most of the pins are for power or for ground.  Simply to get the 100-200A that the chip actually requires from the motherboard's PSU, into the chip itself.  I was questioning whether or not all those pins were required, as opposed to just one giant pad for Ground, and another for Power. 

 

Ground, for instance, could even be the other side of the package, ie: the heatsink side of the chip.  If 2000 pins are power/ground, you could save 1000 pins if you just turned the heatsink into a giant ground.

Dont forget each of these is 200w of power that has to go in, and 200 watts of heat that needs to come out, together with the stupid socket size and 6 dimm slots..

 

I dont think you'd be able to fit more than 2 width-wise, and depending on crazyness you could squeeze two length wise as well.

those better go triple digits with cores
