Re: Advice on buying laptop... PLEASE
Intel Core-duo is one of the fastest processors around at the mo too.
Its certainly true that duel core is the new standard in processor technology - I would'nt buy any laptop without it (forget old style centrino, celerons etc.) However there's loads of different types around with different spec.
With Intel it generally
ranges from the entry level Core Duo T2050 (1.6Ghz) up to the very fast Core Duo T2700 (2.33Ghz).
With AMD it
ranges from the Turion 64 X2 TL-50 (1.6GHz) to the Turion 64 X2 TL-60 (2Ghz).
In addition to the Intel T2 line mentioned above, a new product called
Intel Core 2 Duo was launched this summer. Its still comparitively expensive and rare, but is probably the top mass produced commercial processor line in the world. It
ranges from the Core 2 Duo T5200 (1.6Ghz) to the Core 2 Duo T7600 (2.33Ghz).
So what does Duel Core mean? Traditionally processors where made up of lots and lots of transistors. To get faster, these where made ever smaller so that more transistors could fit into the same space. A recent enough Pentium 4 processor contained perhaps 50m of these transistors in a single integrated circuit an Itinium 2 launched
scarcely 2 years later contained 500m.
So surely things can't keep getting smaller? Well thats the problem, its becoming increasingly unviable to simply shrink things, so Intel and AMD in there great wisdom decided to sell 2 processors in one. So you could have 2 "cores" each of 250m transitors in the one microprocessor. Thats "duel core". Aside from the obvious numerical advantage, having two cores means the processor can focus on two completely different tasks at once, also theirs power/heat advantages...
sorry if i've bored you all! i'm always fascinated by laptop spec!
