What are the four cores in the CPU?

The quad-core is a processor core that has four functions on one processor based on a single semiconductor. In other words, four of the physical processor cores are integrated into one core. The difference between the quad core and the dual core is that on multitasking, the CPU of the four cores open four programs to open four programs faster than the dual cores CPU, and then the multi-core has more advantages in the operation of large amount of data (for example, the multithreaded floating-point calculation used for the usual test).

Products launched

Intel has launched a number of quad-core desktop chips as part of its dual-core quad and extreme family. In the server area, Intel will deliver a xeons of not less than 9 four core processors in its Low-voltage 3500 and 7300 series.

During the Spring Festival analyst event, Intel stressed that its core architecture includes both dual-core and four-core chips, more than the four core it specializes in. "We will gradually promote our nuclear micro-architecture, with a single, dual and four cores in all market areas," said Paul Otellini, chief executive of Intel Corporation. ”

Unique Features

The Intel processor core features a feature called "Wide Dynamic Execution". More importantly, its power consumption is lower than the NetBurst architecture, which provides processing power for Pentium 4. "We look forward to the full adoption of the nuclear microarchitecture by the end of this year," Otellini said. "We are replacing all the products at a very fast rate throughout the year, even in the areas of the Pentium processor and Celeron processor with a variety of nuclear microarchitecture." This gives us a performance lead in every field and gives us a high cost advantage. ”

However, it is clear that the quad-core will become increasingly important for Intel's progress. Two new quad-core processors using Intel's latest 45nm chip technology may be released at any time in the second half of 2007: Yorkfield for desktops and harpertown for servers.
