Their actual performance per watt is noticeably worse than the P-cores. Efficiency gains come purely from clever utilization that some workloads prefer more slow cores over fewer fast cores and vice versa. P-cores are nearly 2.5 times the performance of the E-cores, but you can get 4 E-cores for the space of 1 P-core.

I have always been confused when it came to how much charge does a battery charge. Let''s say, a phone battery: It says 1900 mAh @3.7 v. Now i know it goes up to 4.2v, but those 1900 mAh are available in the 2.5v ( cut off voltage i think) - 4.2v area or the 1900mAh are available in the entire 0v-4.2v, meaning that some of the battery s energy remains unused, right?

6 FAQs about [How much current does a 16-inch battery have]
How much current can a battery supply?
A battery can supply a current as high as its capacity rating. For example, a 1,000 mAh (1 Ah) battery can theoretically supply 1 A for one hour or 2 A for half an hour. The amount of current that a battery actually supplies depends on how quickly the device uses up the charge. What Factors Affect How Much Current a Battery Can Supply?
How many amps can a 12V battery supply?
Assuming you have a 12V battery that is in good condition, it can supply up to 30 amps of current. The amount of current that a battery can provide depends on its size and capacity. A larger battery will be able to provide more current than a smaller one. How Batteries are Rated?
How much current can a lithium ion battery supply?
The higher the internal resistance, the lower the maximum current that can be supplied. For example, a lead acid battery has an internal resistance of about 0.01 ohms and can supply a maximum current of 1000 amps. A Lithium-ion battery has an internal resistance of about 0.001 ohms and can supply a maximum current of 10,000 amps.
Do batteries need a lot of current?
If you only need the battery for a short period of time, it won’t need to supply as much current as if you were going to be using it for an extended period of time. Finally, you need to consider the temperature. Batteries perform better in cooler temperatures and can supply more current in those conditions.
What determines the amount of current a battery can supply?
The amount of current a battery can supply is determined by several factors. The first factor is the battery’s voltage. This is the potential difference between the positive and negative terminals of the battery, and it determines how much power the battery can supply. The higher the voltage, the more current the battery can supply.
Does a large battery have more current than a smaller battery?
In essence a large battery has greater capacity than a smaller one of the same voltage and hence may be considered as capable of greater current capability. As to maximum current, it all depends on chemistry, how long you want to draw current, how much money you have to spend, etc.
