Part 3. Processor generations and the consequence of picking the right sized VM Selling Azure migrate By the CloudLab
Moore's law is the observation that the number of transistors in a dense integrated circuit (IC) doubles about every two years.
Instruction Set This is the processor's built-in code that tells it how to execute its duties. The processor's architecture and instruction set determine how many cycles, or ticks, are needed to execute a given instruction. Multiple cores and multi-threading Processors run two (dual-core) or four (quad-core) times faster than a single processor. Multi threading improves performance by allowing multiple CPUs to work on a problem at the same time but too much multithreading is just as much a problem as too little. Clock Speed The clock speed (or clock rate) is stated in megahertz (MHz) or gigahertz (GHz) and refers to the speed at which the processor can execute instructions. The faster the clock, the more instructions the processor can complete per second. Bandwidth Measured in bits, the bandwidth determines how much information the processor can process in one instruction. The current bandwidth standard is 64 bit Front Side Bus Speed The FSB is the interface between the processor and the system memory. he CPU's FSB speed determines the maximum speed at which it can transfer data to the rest of the system. On-Board cache The on-board (or "on-die") cache is a relatively small amount of high-performance SRAM built directly into the processor, a processor with more onboard cache will outperform a processor with less onboard cache. Looking at all the numbers doesn't always tell the whole story of how well a processor will function in the real world. It's also why when choosing a processor, benchmark tests that measure the chip's abilities to do real-world work can be very useful. Factors affecting CPU performance
Passmark CPU Benchmark results ( Baselines ) are gathered from users submissions to the PassMark web site as well as from internal testing. PerformanceTest conducts different tests and then averages the results together to determine the CPU Mark for a system. Passmark Benchmark rating Passmark CPU Benchmark method

This will help you easily identify which SKU is most likely to satisfy your performance needs. ACU is currently standardized on a Small (Standard_A1) VM being 100 and all other SKUs then represent approximately how much faster that SKU can run a standard benchmark F(s)v2 195-210 2:1 E(s)v3 160-190 2:1 Ea(s)v4 230-260 2:1 E(ds)v4 195-210 2:1 (D(s) 11-15 210-250 1:1 M 160-180 2:1 Mv2 180-280 2:1 Microsoft s own benchmark: Azure Compute Units Important: The ACU is only a guideline.
