How many cores in one die?
Rumor is 15 with one disabled for yield.How many cores in one die?
Anyone else hoping for HEDT of 418mm^2 of 10nm silicon?
56 is too few imho.

There's no DDR4 IMCs but otherwise yes. Most of the die area for each of these chiplets are going to be filled with I/O.Regarding the die size, keep in mind the die covering the top SKUs will feature a massive amount of next-gen IO - HBM2 & DDR5/DDR4 memory controllers and PCIe 5 with CXL 1.1 functionality. Also the amount of required additional "MCM glue logic" is unknown at this point.
The current-gen 4 Willow Cove client cores including L3 are around 43mm2 on the Intel Super 10nm. 16 of them should be over 170mm2. That's excluding the whole IO, probably larger L3 and Golden Cove size increases.
Looking at the XCC Cascade Lake, the "uncore" occupies roughly 40% of the die size. So 16 cores seems a bit low. 20 of them would take a bit over 210mm2. That would fit that 418mm2 chiplet a bit better.

My bad, DDR4 is for ADL. The server platform makes sense to be DDR5 only.There's no DDR4 IMCs but otherwise yes. Most of the die area for each of these chiplets are going to be filled with I/O.
I suppose that Saphhire is going to end up being a HPC only product.
Alder Lake is already DDR5.My bad, DDR4 is for ADL. The server platform makes sense to be DDR5 only.
The HBM SKUs will surely be aimed towards HPC, although the conventional DDR ones might be fine for general purpose.
Alder Lake is already DDR5.

New GB5 score of what looks like a retail 11900K. 1894 is really good for ST.
Yeah, that would be a pretty big increase. A 10900k scores ~1400.

That would be a 35% increase. That's... higher than my reasonable expectations, I guess. That would be sweet if true
Memory has little to no effect on GB5 at all. On my 5950X I saw no improvement in performance between JEDEC DDR4-2133 and DDR4-3200cl16.Actually it broken the 1900 barrier: https://browser.geekbench.com/v5/cpu/6348421
The AES score is a small part, the IPC at 5300 Mhz is higher than on Tigerlake-U 4700 Mhz. This RKL-S sample uses DDR4-3600 and tighter latencies. Tigerlake-U runs with DDR4-3200 CL22 or LPDDR4-4266 CL36 and this might have run with DDR4-3600 CL15. Bandwidth isn't really important for ST workloads unlike latencies.

I suppose that could work if they keep the tile structure in the core. 15 cores plus one IMC one. 16 tiles does seem low for 418 mm2 but I wouldn't say it's wrong either.
