All the CPUs support DDR4-2933 in dual-channel mode, except for R7 2700E, R5 2600E, R5 1600AF and R3 1200AF which support it at DDR4-2666 speeds. All the CPUs support 24 PCIe 3.0 lanes. 4 of the lanes are reserved as link to the chipset. No integrated graphics. L1 cache: 96 KB (32 KB data + 64 KB instruction) per core. L2 cache: 512 KB per core.

Ryzen 3 PRO 2100GE [2] found in some OEM markets in limited quantities. Ryzen (/ ˈ r aɪ z ən / RY-zən) [3] is a brand [4] of multi-core x86-64 microprocessors, designed and marketed by AMD for desktop, mobile, server, and embedded platforms, based on the Zen microarchitecture.
The dynamic power (switching power) dissipated by a chip is C·V 2 ·A·f, where C is the capacitance being switched per clock cycle, V is voltage, A is the Activity Factor [1] indicating the average number of switching events per clock cycle by the transistors in the chip (as a unitless quantity) and f is the clock frequency.
Clock signals. The signal on this line is used to synchronize data between the CPU and a device. Reset. If this line is active, the CPU will perform a hard reboot. Systems that have more than one bus master have additional control bus signals that control which bus master drives the address bus, avoiding bus contention on the address bus. [1]
1: add 1 to R5 2: copy R5 to R6 If the processor has the 5 steps listed in the initial illustration (the 'Basic five-stage pipeline' at the start of the article), instruction 1 would be fetched at time t 1 and its execution would be complete at t 5. Instruction 2 would be fetched at t 2 and would be complete at t 6.
On x64 processors in long mode, it (and the other control registers) is 64 bits long. CR0 has various control flags that modify the basic operation of the processor. Register CR0 is the 32 Bit version of the old Machine Status Word (MSW) register. The MSW register was expanded to the Control Register with the appearance of the i386 processor.
