The current lineup of Core processors includes the latest Intel Core i7, Intel Core i5, and Intel Core i3
The current range of Macintosh computers use a range of Intel processors; Core 2 Duo, Core i3, i5 and Quad core i7 or the 6 core Xeon.
yes
The second generation processors are much better
Intel Core i3 is faster even though they are both dual core processors. The i3 has multi-threading capability which lets it run two processes on one core versus one process per core the the Intel Core 2 duo. Bottom line: Intel core i3 is faster.
A variant when it comes to processors refers to related models of processors. For example, a variant of the Intel Core i3 processor is the Intel Core i5 processor.
The Core i3 is a low-end processor line made by Intel. Some specifications are listed below: Core i3-530 - 2.93 GHz dual-core, priced at $113 Core i3-540 - 3.07 GHz dual-core, priced at $117 Core i3-550 - 3.20 GHz dual-core, priced at $138 Core i3-560 - 3.33 GHz dual-core, priced at $138 All of these processors are available on Intel's LGA-1156 socket, and are on the low end of Intel's Core lineup. AMD makes a comparable, but much less expensive, line of dual-core processors called the Athlon II X2 series.
This depends on what type of A-Series you are talking about, but the i3 is better than the Pentium Dual Core although they are based on the same microarchitecture.
As of 3/14/2010, Intel's latest processors are the Core i series. The Core i series consists of the Core i3, Core i5, Core i7.
Intel Core i5 i5-7xx, Core i7 i7-8xx, Xeon L34xx, Xeon X34xx, Celeron G1xxx, Pentium G6xxx, Core i3 i3-5xx, and Core i5 i5-6xx. The 'x' represents any number.
difference between dual core and core i3
The Intel "iCore" line is Intel's newest line of processors. The lowest, the i3, is to replace the Core 2 Duo series while the i5 replaces the Core 2 Quad series. The i7 is a brand new series quad-core series. The iCore ranges from a dual-core (i3) up to the newest addition, a hexa-core (i7 Extreme). The best feature about the iCore line is their HyperThreading Technology, meaning it has two processing threads per core. Basically it means that a dual-core will simulate a quad-core while a quad-core simulates an octa-core. It also utilises a new architecture, so if you have the older Core 2 processors, you'll need a new motherboard to support an iCore upgrade. Data transfer speeds are a lot faster due to the replacement of the frontside bus by Intel's Quickpath InterConnect.
