Is it worth it to own a CPU with more cores, a faster clock-speed or advanced features like hyper-threading? If you're building your first PC, the main thing you need to keep in mind here is that the 3, 5 and 7 attached to each family of Intel Core processors are simply meant to be indicative of their relative processing power.
Which family an Intel Core CPU falls into is based on a collection of criteria involving their number of cores, clock speed in GHz and cache size, the number of Intel technologies they integrate also plays a role.
At the most basic level, these numbers reflect where each class of Intel Core CPU sit relative to one another and are intended to give consumers an idea of the kind of performance they should expect from each. Essentially, the idea that Intel are looking to convey with this CPU classification system is that PC builders should expect:. Some are intended for us inside laptops, others are intended for use with desktop PCs.
Wattage is the big differentiator here, since CPUs inside mobile devices generally have to make do with less power draw,. However, to avoid confusion, let's start by exclusively talking about the desktop variants.
This means that a PC with a higher core-count is going to be better for tasks where multithreading is important, such as web servers, web browsers and some video games. The reason for this is that i3 processors are designed to hit a lower price-point more than they are push boundaries for performance.
They tend to be found inside PCs that target a more budget-conscious market-segment where the need for a device to be affordable eclipses the demand for higher performance. The CPU requires a fixed number of clock ticks, or cycles, to execute each instruction. The CPU speed determines how many calculations it can perform in one second of time. Clocks speed are measured in very basic increments in Hertz , abbreviated as Hz. One Hz means once a second.
So, if your CPU has a 3. The highest clock cycles on processors available today is around 4 GHz. If you double the speed of the clock, leaving all other hardware unchanged, you will not necessarily double the processing speed. The other components like RAM, hard drive, motherboard, and the number of processor cores e. It is where your processor pretends to have 2 physical processor cores, yet only has 1 and some extra junk. It's available on Core i7 and Core i3 , but not on the mid-range core i5.
Hyper-Threading Technology uses processor resources more efficiently, enabling multiple threads to run on each core. As a performance feature, it also increases processor throughput, improving overall performance on threaded software. The point of hyperthreading is that many times when you are executing code in the processor, there are parts of the processor that is idle.
