All from my friend as he bought and delided one. We also heard that this unit currently only has 1 of 4 dies active with 28 cores. He's trying to find a eval board for this thing to test it himself.
Seems to be 4 HBM pads on the corners that aren't soldered though.
4 big dies all together connected with co-EMIB(more than 112 cores per package?), no discrete north bridge, and an Altera FPGA. The 4 missing die positions may be reserved for HBM or silicon-photonic devices.
Trying to evaluate the power consumption to see what frequency the CPU actually runs at in rendering. Here's where I noticed something interesting. The 4.0GHz 9900k actually beats 3700x(4.05G) by more than 20w in rendering. The voltage is auto(default p-state frequency-voltage pair).
The first picture is an official image from AMD. I can't find any reliable image for intel skylake/cascadelake so I drew it myself. Made this to compare the size of each components for different vendors.
If there is any problem please tell me, not very sure about the"execution ports" part.
I was using microarchitecture exploration mode of vtune 2020. The problem mainly came from "port utilization" tab, where I thought the four "cycles of n ports utilized" should add up to be 100%, but their sum is lower than that.
I did this test on a variety of applications, but none of them...
