Alpha 21264A 667 MHz processor

Advantages: The first portable super computer
Disadvantages: no more expansion bays

...Now - you must be wondering why you should buy a laptop for more than 2000 pounds with a chip speed of 667Mhz. Well - the answer is in the "G4" bit of the name. The Motorola G4 processor is the first processor to achieve preformance of more than 1 gigaflop sustained (1 billion floating point operations per second) - so it is technically a supercomputer. There are two flavours - 550Mhz and 667Mhz. Apart from the usual increase in RAM and HD, the 667 has a 133Mhz main bus as compared to 100 on the low end. As for shared specs, they really are quite juicy, sporting radeon graphics, DVD/CDRW slot-loading combo drives and a wonderful 15" widescreen display that is wonderful for DVD movies. It also has a good array of ports, with modem, 10/100/1000 (yes - gigabit) ethernet, USB 1.1, Firewire, IRda, s-video out, VGA out (with support... Read review

Advantages: Fast, Really Fast
Disadvantages: Noisy

...Processor Is Fairly Fast, But Over Heating , Even With Original Intel Cooling Is A Regular Problem. It Don't Seem To Work Well With My MSI NEO2 Motherboard. The Huge Cooling Fan Makes A Lot Of Noise And Vibration. After Changing The Thermal Gel The Vibration Is Lot Less Now. But Every Time I Put Up A Huge Processing Task The Processor Fan Speeds Up And The Vibration Returns. My 533MHz DDR2 RAM Works Fairly Well With The Processor. The Motherboard Though Support 667MHz RAM As Well. I Have Tested Once With A 667MHz 512MB RAM And The Performance Boost Is Quite Insignificant. Have Put It Through A Mega Processing Task. I Put That Exact Task on A PIII 800MHz With Same Amount of RAM and The Required Time For The Later Was A Multiple of 6(almost). The Duel Core Really Works.... Read review

Advantages: very fast, capable processor, very cheap
Disadvantages: faster fan needed for overclocking

...This is an extremely capable mid range processor. If you are looking to upgrade your computer to a very good standard without having to pay hundreds of pounds then this is the processor for you. I have had this processor for just over a week now and it has proved to be very good. The 3.20 GHz clock speed is extremely fast and is capable of running most applications to a very good speed. Also the fact that it is dual core has really impressed me. All this for such a cheap price. There is a 2x2mb cache on this which is very good, you would get better with the £300+ processors but for this price it is very good. I have this set up with an as rock motherboard and 1 GB of ddr2 667 MHz memory. This runs very well and is very smooth for intensive applications such as video editing. This processor is a socket 775 one which you need... Read review
