Intel 10nm process because the yield is not up to standard, mass production has been postponed to 2019, now only small-batch shipments, the product is known only a low-power version of the 15W thermal design power Core i3-8121U (family code Cannon Lake ), and only Lenovo is using it.
i3-8121U specification is dual-core four threads, clocked at 2.2-3.2GHz, three-level cache 4MB, memory support dual-channel DDR4/LPDDR4-2400 32GB, thermal design power consumption 15W.
The information of the nuclear part was not published. It should be because the yield problem was disabled. So Lenovo added an AMD discrete graphics card.
ComputeBase, the German hardware media, revealed the first 'fruit photo' of i3-8121U. The package layout is basically the same as the previous product. It is still a processor core. One chipset core is packaged together, and the BGA integrated package is soldered on the motherboard.
We also found an Intel official version of the eight-core Core low-voltage version of the photo, you can find the processor, the chipset core has become smaller, the package solder joints and capacitive components have also undergone great changes, it should be no longer compatible.
ComputeBase measurement found that The overall package size of the i3-8121U is 45 x 24 mm (consistent with the official specifications), where the processor area is approximately 71 mm2 and the chipset is approximately 47 mm2.
Although according to the study, the transistor density of the Intel 10nm process exceeded 100 million cells per square millimeter, which is equivalent to even higher than that of Samsung, TSMC, and GlobalFoundries at 7nm, but the change does not seem to be large compared with its own 14nm product.
To know, Intel's first-generation 14nm Broadwell-U processor also has an area of only 82mm2, 10nm is only 13% smaller, and everyone is dual-core four-threaded, all 4MB three-level cache, but only the execution unit from the core 24 Increase to 40, and support AVX512 instruction set.
In addition, the 45 x 24 mm overall package is slightly larger than the current 14 nm low-voltage version of 42 x 24 mm.
