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 ! 

It is known. It tops out at 72 and iirc 1300 MHz. It's a 7TFlop chip.

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.

You can fit 8 of these in a 1U. Dell already has a design for it. 4 CPUs and 4 accelerators. A 2U form factor can hold 20: 8 CPUs and 12 accelerators.

those better go triple digits with cores

72 cores per socket, with 4 threads per core and 7TFlops per chip. Also, they have a 100GB/s optical interconnect option called OmniPath. The L3 cache I think is also almost 200MB, and the L2 cache for each core is somewhere around 512KB, and another 64KB at L1. Cache is the most spatially expensive part of any IC, and the circuitry which is both the memory cells and the paths by which data travels to the register file and compute units is 95% of a CPU die (Herb Sutter).

I'd imagine they're the price of a fairly nice car.

No, they'll top out at around the same price as the flagship E7 Xeons, or about $8000 a piece. That's a nice used car about 1 year old.

72 atom cores for the highest end one with 4 way hyperthreading for a total of 288 threads. The lowest end model has 68 cores iirc.

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

It's good to voice your opinion, but not like that

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

2? you must mean 4  quad socket all the way

so dual hyperthreding sortof? thats pretty freaking cool

Power 8 does 8 threads per core. I'm pretty sure Oracle's Sparc M7 is either 4 or 8 threads per core as well. It's just SMT taken to greater and greater extremes.

thats crazy and why havent i ever heard about it before?

Because Power and Sparc aren't used much outside of supercomputers and bank/financial institution mainframes. They're used sparingly and are partly security through obscurity. Also, IBM sells its Power 8 servers to the tune of about $2500 per CORE. 12 cores per socket max, though the flagship 12-core Power 8 can run at 4.7GHz in a 250W TDP. It's called a scale-up design. Without getting too technical, it has advantages for transactional workloads because it has fewer, faster cores.

Have at it.  Pin groups 26 through 45 are power or ground.

That's not even half, let alone most.

Well Knights landing has 72 cores,  but they are atom cores.

They didn't even bother cleaning the thermal paste off the broadwell chip?

Oh my God Noctua finally does something right and just makes a 212 Evo but with a better mount!

And here I thought they'd try to get away with a triple-tower cooler next...

Lol at the Noctua cooler in the back.

No Evos, only Noctuas. It's just 1 cooler, 1st pic standing up and 2nd lying down.  This was at Computex.

Just found out, it's Noctua 212.1 Evo.

Well, no more removing cooler when pc is standing up.

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.

Oh damn forget knights that's gonna sound like a Jet Landing.

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. 

I was just trying to explain why they couldn't just have a massive ground portion on one side of the CPU. The heatsink idea is possible but then there will be slight variations based on different heatsinks, it would also need contatct pins on the top and bottom of the cpu (at least internally).
