Clock speed is one of your CPU’s key specifications. Learn what CPU speed really means and why it matters.
nm stands for nanometer, a unit of measure for length. 1nm is equal to 0.000000001 meters—which is absolutely minute. In a CPU, nm is used to measure the size of the transistors that make up a processor. There arebillions of transistors in a CPUthat perform calculations through electrical...
Processor speed, also known as clock speed or CPU speed, is a measure of how many cycles a CPU can execute per second. It’s typically measured in gigahertz (GHz). For example, a CPU with a clock speed of 3.0 GHz can process 3 billion cycles per second. ...
TDP is a measure of how much heat a CPU generates under normal operation. Generally speaking, CPUs with more cores will have higher TDPs since they require more power to operate at full capacity. Can I disable some of my CPU cores to save power?
Clock speed is often incorrectly understood as the number of operations that your CPU can perform in a second, but this isn’t completely accurate. Clock speed is a measure of how many cycles a CPU can perform per second. It is measured in Hertz, which is a unit of frequency. A 2 GHz...
I used log-log plots above. These make it easy to interpret the overall performance ("x is faster than y when it's longer than 1000 elements") but they make it hard to quantify (for example "it's 3 times faster to do x than y"). So in some cases other kinds of visualization mi...
Do I want to optimize an application to provide service in a certain way, for example "this apache webserver should be able to hand out as many static files (fetched from storage) as possible"? With the goal clear, one can decide on the best tool to measure. Applications can then be ...
Basic Service = 3 to 8 Mbps. Medium Service = 12 to 99 Mbps. Advanced Service = 100 Mbps. Mbps (Megabits per second) is the standard measure of broadband speed. It refers to the speed with which information packets are downloaded from or uploaded to the internet. *Speed usage data is...
beforefoo, betweenfooandbar, or afterbar. It could even be the case thatbazexecutes before therdtsc, as long asbazdoesn't affect the move instruction in any way. There are some circumstances where that would be fine, but it's not fine if therdtscis there to measure the execution time ...
We measure CPU performance using instructions per cycle (IPC). The number of cycles per second, meanwhile, depends on the CPU’s clock speed. That can be as high as 6GHz on desktop CPUs or 3.2GHz on mobile chips like the Snapdragon 8 Gen 2. Latest deals on top techSee all deals Pre...
