A desktop processor is cooled by a cooler that often has more than twice the cooling capacity of an ordinary laptops processor cooling system.
Even the low end desktop coolers, such as the stock cooler that Intel ships with its processors can vastly outperform the cooling power of even a relatively high-end laptop. Once a processor has more thermal headroom available to it. It can attain higher clock speeds, and sustain them for a much longer period, than a laptop.
Which ultimately means more performance for the desktop processor. This is the reason why laptop processors are also often plagued by overheating issues. There temperatures begin rising dramatically. While desktop processors usually hover around 70C to 80C when under load.
In an effort to stop themselves from overheating, laptop processors begin dramatically reducing their clock speeds to bring temperatures down. The TDP rating is the maximum amount of heat that a processor is expected to generate. And due to the cooling limitations we just discussed, laptop processors come with a much lower TDP rating than desktop processors.
More cores means these CPUs can handle more threads at once and faster clock speeds mean they can complete tasks more efficiently.
At this point, you may be wondering just how important clock speeds are. The answer: pretty important. The first is that, in general, a higher clock speed is better. However, due to the thermal issues involved, processors with more cores tend to operate at a lower clock speed.
Often-times, choosing a CPU involves choosing between a CPU capable of delivering faster clock-speeds or choosing one with more cores. Although a faster core might be more efficient than a slower one, it might not necessarily be better for the tasks you want to use your computer to be better at.
Many applications only run single-threads while others are designed to utilize multiple. For cases where the latter applies, such as video rendering and gaming, having more cores is going to offer up an enormous improvement over having faster ones.
Rather than run out and dropping the cash on the CPU with the fastest clock speed you can find, it might be worth thinking about what the clock speed you actually need looks like. To that end, it's worth looking up the recommend system specifications for the game or software you'll be running on your new PC.
For more everyday things like web browsing, an i5 processor with a higher clock speed is probably going to offer more bang for your buck than a beefier i7 might. Other elements include GHz speed, power consumption and the number of cores. Most operating systems, applications and games will accept processors from either company. There are a few differences, though. Intel is considered to be the leader in speed and performance.
However, the trade-off is in price, as Intel is generally more expensive than AMD. AMD's processors may not be as fast as Intel at identical GHz, but they are cheaper and are able to handle integrated graphic cards better. Gigahertz, commonly abbreviated as GHz, identifies the speed of each core in the processor.
