Once there was only one core - a decade of processors

From one primitive core to a five-core monster, one of which is a video card - a very interesting decade for us in the field of processors.
At 2001, when the site came into the world, the processor market had just gone into high gear: the GHz barrier was crossed, first by , Then also by . The latter, which to date leads the market for processors both technologically and in terms of market share, 4, in the hope that high frequency will compensate for the low processing efficiency of the architecture.
Partly trick managed. The Pentium 4, which in addition to the high frequency also added several sets of new commands, did not display more processing efficiency than the Athlon MP, but the larger clock speeds looked good on the billboards, which sold, Sold its processors at the price of Pentium 3, which it left To lower markets.
Not just clock speed
Here we must pause for a moment and explain that the capacity of a processor is not measured solely by its clock speed, but also by its ability to cope quickly with specific calculations. When we say "command set" we mean the number of units in the processor that are built for specific calculations such as video editing, images, audio, compression or file deployment, encryption and even games. Of course, software support is needed, but this is a very small disadvantage once they are both Intel processors and processors Contain the same set of commands.
CPU + AMD 1500
With Palomin's core
The problem with the Pentium 4 was That he was hot. So hot that Intel was the first to develop a diode that would turn off the processor as soon as it was dangerously hot. Of course, the problem could be solved by purchasing a larger cooling unit (which the hardware professionals did anyway, for the processor to speed up), but She could not let her reputation go down the drain. Instead, the company began a process that continues to this day: reducing the production process of the processors.
Imagine a cake: you can cut the same cake (300 nanometer square, for that matter) into slices of 180 nanometer (the Willamette core, with the irritating tendency to die from warming), but also to smaller slices of 130 nanometers . In which situation will you get more slices? Of course, in reality reducing the slices means finding a way to reduce the distance between the transistors while preventing electrical leakage between them, but the process also has other advantages but more Per wafer, reducing heat emissions, reducing power consumption, and the ability to work at higher frequencies.

על ידי In 2009
If Intel can reduce the Willamette from the production of 180 nanometers to a production process of 130 nanometers And get a successful Northwood core, is also Can do the same thing. The core of the Palomino Has also been enhanced to the production of 130 nanometers, now called Thoroughbred. This is where Intel has an advantage in terms of marketing, since the Pentium 4 with the Northwood cores reached tremendous frequencies for the time of 2.6 and even 2.8 GHz, while the processors of They found it difficult to keep up, but were more efficient. Processor from home , Such as the Athlon XP that captured the hearts of hardware enthusiasts at that time, the frequency of 1.8 GHz could display higher performance than the processor of At a frequency of 2.4 GHz (which is without reference to price differentials for AMD).
AMD has the advantage, though Leading
In 2003, AMD had new competitors in line with Intel's aging Northwood, which also achieved performance in games and multimedia. The Athlon XP 2X00 +'s strong points were low cost and high frequency efficiency, which AMD also worked on in next-generation processors: the Athlon 64 (which we published at the time) Comprehensive site review). In these processors, the memory controller of the chipset system migrated to the processor core, and here AMD made a gamble Processor support for 64 bit (Ie, the ability to process larger pieces of information in each clock cycle relative to the 32 bit processor, such as Intel's) will persuade consumers to favor AMD's processors?

Willamette core owner
To date, the entire PC market has not undergone a storm to be processed on the 64 bit (although it happens, slowly but surely), but this convinced the hardware professionals Preferred. That, and test Encompassing the cost-benefit ratio (which was preferable to AMD). This situation continued for the next two years as well One to one core became a two-core battle against two cores.
In 2005, we already had 90 processorsSan Diego and Venice (accolades), From AMD, and the market situation was such The core market was high, And were keen to the lower markets. AMD's advantage in the battle is maintained, Since two efficient cores led to performance on two less efficient cores of the same frequency. Nevertheless, in Israel they continued to buy Intel, both because there was no orderly import of processors To Israel, and because what did come was too expensive.
The big argument was about the need: "Why do I need two cores if most of the software I use only uses one?" The immediate answer was video editing software, audio and images, which learned to take advantage of more than one core, and of course the fact that cores worked much better with multitasking, such as playing while compressing or spreading files. A few years later both games learned to utilize two cores (or more, we have not yet talked about Triangular And quadrature cores), and today dual-cores remain the option for the cash bucket or those who do not need large processing power.
