Does clock speed apply to each core?
Clock speed is rather a count of the number of cycles the processor goes through in the space of a second, so as long as all cores are running at the same speed, the speed of each clock cycle stays the same no matter how many cores exist.
Is clock speed or cores more important for gaming?
For many tasks, clock speed is more important than core count: Higher clock speeds translate to snappier performance in simple, common tasks such as gaming, while more cores will help you get through time-consuming workloads faster.
Can a processor run at the full clock speed?
Under full load (that is, when you have programs running taking up all available processor time on all cores), all cores will run at the rated speed (eg, an 8-core 2 GHz processor runs all 8 cores at 2 GHz). Now, it is possible for the cores to be running at different speeds, depending on the actual load:
Why do CPU cores all have the same speed instead of different ones?
In ARM-based devices which implement big.LITTLE, the processor contains cores with different performance and power profiles, i.e. some cores run fast but draw lots of power (faster architecture and/or higher clocks) while others are energy-efficient but slow (slower architecture and/or lower clocks).
Why are there no variants with differing clock speeds?
Why are there no variants with differing clock speeds? For example, two “big” cores and lots of small cores. Instead of, say, four cores at 4.0 GHz (i.e. 4×4 GHz, 16 GHz maximum), how about a CPU with two cores running at 4.0 GHz and four cores running at 2.0 GHz (i.e. 2×4.0 GHz + 4×2.0 GHz, 16 GHz maximum)?
How many processing units does a multi core processor have?
A core is a single processing unit, multi core processors have multiple processing units. So a dual core 3.0GHz processor has 2 processing units each with a clock speed of 3.0GHz. A 6 core 3.0GHz processor has 6 processing units each with a clock speed of 3.0GHz.
