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.
core its faster
All intel processors Pentium 4 and down were single-core, or "core solo" processors. They weren't called "Core Solo," but by what respective family they came from. Pentium I, II, III, and 4.
Both processors are in the Pentium Dual Core family. The Pentium Dual Core E2200 is better than the other.
Intel offers Pentium Pro, Pentium II, Celeron, Pentium II Xeon, Pentium III, Pentium II and III Xeon, Celeron with Pentium III Based, Pentium 4, Pentium M, Intel Core, Dual Core Xeon LV, Intel Pentium Dual Core, Intel Core 2. Pentium Duo, Pentium Dual Core, Core 2 Quad, Intel Pentuim 2 Dual Core PrAMD processors include AMD Athlon, AMD Athlon 64, AMD Athlon X2, AMD Athlon Xp, AMD Duron, AMD Sempron, AMD Turion, MD Opteron and AMD Phenom 1.
Yes. The Intel D945GNT motherboard supports dual-core Pentium D processors.
Pentium 4 is a family of Intel processors with one core based on the NetBurst architecture, but some types support Hyper-Threading technology that exposes an additional, "virtual" core to the OS. Core 2 Quad is another kind of Intel processors with four cores, based on the Intel Core architecture.
Intel Corporations manufactures their own products. They outsource to other countries, but the factories are owned by Intel. There is very little information on the manufacturing process of Intel.
The Intel Pentium Dual-Core is much faster.
The difference is that Core Duo processors have to "engines" instead of one. With other words, Core Duo means 2 Intel processors in the same time working!
The Intel Pentium line encompasses many processors of many different architectures ranging from the original Pentium Processor of 1994 up to the Core 2 Duo based Pentium simply called the "Pentium". The Intel Pentium used to be Intel's flagship processor. Recently this position has been taken by the Core 2 Duo and Core i7. The Pentium now is reduced to a budget processor that offers lower performance but also lower cost.
Intel Core
A single core processor is just that... one processing core. A dual core processor is actually two processing cores on one chip. It is like having two processors in your system, but it is faster than two individual processors.
