AMD recently officially released the Ryzen 4000U, Ryalong 4000H series mobile APU (code Renoir), using 7nm technology, Zen 2 architecture, up to eight CPU cores, eight GPU computing units (512SP), thermal design power consumption 15/45W. After the launch, AnandTech visited AMD’s booth and was pleasantly surprised to find a nude piece of the Ryzen 4000 APU, alongside a nude piece of the 64 core 128 thread tearer 3990X, and measured their core area.
The three generations of Ryzen and the third generation tearers feature a chiplet chip design, each with eight cores, with a measured area of 10.32 x 7.24 x 75.75 square millimeters (official core area of 74 square millimeters plus some extra padding).
The verification length of the Ryzen 4000 APU is 13.59 mm in length and 10.98 square mm in width, with an area of 149.27 square mm.
Such an area, combined with TSMC 7nm process per square centimeter 0.09 defect indicators, Rylong 4000 APU yield is about 90%, although this does not take into account the manufacturing yield, but also considerable.
In addition, before the release of the Ryzen 4000 APU, there was speculation about how AMD would design, whether it was four CPU cores plus more GPU cores, or eight CPU cores plus fewer GPU cores.
As a result, AMD not only plugs in eight CPU cores, 15W thermal design power consumption acceleration frequency of 4.3GHz, but also put in eight GPU computing units and claims to be 56% higher performance than the previous generation, very subtle, very difficult.
Incidentally, the GF 12nm process manufactures the Ryzen 3000 APU with an area of 209.78 mm2 with four CPU cores and 11 GPU units.
The Intel Tiger Lake area of the 10nm plus process is 146.10 mm2, with four CPU cores and 96 GPU units (of course, AMD/Intel GPU units are not directly comparable).
