Difference Between Core Solo & Core Duo Intel Processor
The Core Solo and Core Duo were the first central processing units released under Intel Corp’s Core brand, which would displace Pentium as the company’s premier line of processors for personal computers. The semiconductor giant differentiated the CPUs according to number of processing units: the Core Solo is a single-core chip, while the Core Duo is a dual-core chip. Intel produced seven Core Solo and 15 Core Duo processors.
The Core Solo and Core Duo are split into categories, depending on their energy efficiency and number of cores. The ones with standard power comprise the “T” series, and those with ultra-low power consumption are collectively called the “U” series. The Core Duo has a third designation, “L,” for the middling low-power chips. With the Core Solo, each CPU’s name consists of the one-letter prefix, the number “1” for the single processing unit on the chip, and two additional digits. The Core Duo uses “2” instead, signifying its two processing units. As a dual-core CPU, the Core Duo has twice the amount of processing power as the Core Solo.
Speed and Motherboard
Clock or processing speed on the Core Solo ranges from 1.06GHz on the U1300 to 1.86GHz on the T1350. The slowest Core Duo, the U2400, matches the processing speed of the U1300. However, the fastest Core Duo, which is the T2700, surpasses the T1350 with 2.33GHz. An interface called the front-side bus connects the CPU to the components of the computer’s motherboard at a speed of 533MHz or 667MHz. Each processor is fitted on the motherboard with one of two CPU sockets called Socket M and BGA479.
Cache and Power
The Core Solo and Core Duo has two levels of cache, with the L2 cache providing 2MB of storage space for fast data access. Peak power consumption on the Core Solo is 5.5 watts on the U1500 to 31 watts on the T1250. The Core Duo is generally a less power-conserving processor. At 9 watts, the U2400 and U2500 are the most energy-efficient Core Duo chips. Ten of the Core Duo processors consume as much power as the Core Solo T1250.
Intel began phasing them out in 2007 and they are now discontinued. At the time, the company was shifting towards using the 45nm lithographic node to manufacture smaller CPUs; the Solo and Duo were 65nm processors.
