ARM A9  (Source: CNET News)
A9 can go all the way up to quad-core for smartphones

The smartphone world is filled with handsets running ARM processors. Many of the most popular smartphones around including the iPhone 3G S and the new Palm Pre run ARM-based processors. A new ARM processor architecture is due to hit next year that will greatly increase the performance that smartphones offer.

The new processor is the ARM Cortex-A9. The current Cortex-A8 used on devices like the Palm Pre and is a single-core processor. The A9 set to debut early in 2010 is a dual-core processor. ARM says that while the new A9 architecture is a dual-core chip, it will still offer users increased battery life in daily usage compared to current single-core ARM processors.

The reason the processor can offer significantly higher performance and still give better battery life is due to the construction of the new A9. The A9 will be built using a 45nm process whereas the current A8 uses a 65nm process.

ARM wireless segment manager James Bruce told CNET News, "You'll definitely see handsets shipping with a dual-core A9 in 2010." He continues saying, "the A8 is just a single core while the A9 will be dual-core, all the way up to quad-core to give smartphones an even bigger performance boost."

The new A9 processor operates inside the 300-milliwatt power envelope that is the golden rule in the mobile phone industry. By comparison, the wildly popular Intel Atom processor needs 2,000 milliwatts, but future Atom versions codenamed Moorestown will bring Atom power levels to the realm of smartphone usability.

Other than performance improvements of compared to that of the A8, the A9 will also allow smartphones to support 1080p video along with HD video recording and playback.

Twenty years ago, there was not any GPU


Uh... GPU = Graphic Processing Unit. But yes, there has always been "graphic chips". Sure GPU was termed by Nvidia to describe their 3D Graphics chips. So the GPU term is valid. The Amiga was the first 16/32bit computer to have a dedicated video chip, rather than the CPU doing graphics.

The Macintosh is still "a" PC, as was/is the AppleII, Commodore64, Atari 400 and STs.

Also CPU were not clocked at 25 MHz. Maybe Motorola chips,


MC or Intel - 20 years ago, we had 25mhz CPUs. If you want to be technical, MC 680x0 are double clocked internally. CPUs were based on their system clock. My 1990 Amiga 3000 had a retail price of $2500 with a 25mhz/50mbHD/5mb RAM. (4 slots, no modem, no CD-ROM drive)

The 80386 was at 25mhz in 1987, typically found in high end Compaq & IBM PS/2 computers ($5000+) as was the MC68030 for Macs, Amigas and Atari computers (These had GUIs) which added about $1000~1500 to the price of a computer compared to the 8~16mhz computers. IE: Amiga2000 @ 7mhz was about $1200 ($500 for the A500). With 68030 card, the A2000/2500 was closer to $2000+ until the A3000 was released.

So yeah... when someone complains about expensive computers, I laugh at them. I paid $280 for a 5.25" 320K floppy drive... its bigger & heavier than my dualcore Thinkpad.

What $600 got you:
1989: Amiga 500: 7mhz CPU / 1mb / 880k Floppy / 3096 colors (640x200)/ RGB output.
(You paid $300 for a 13" monitor, $100 for a 1200 modem - this was the "cheap" affordable computers of the 80s)

2009: Lenovo IdeaPad Y550: 2000Mhz Core2Duo / 4000mb / 320GB HD / DVD-R / Modem / Ethernet / 15" LED LCD monitor / 16 million colors in 1266x768. No floppy drive, $30 option.

Cool #1: 1987 Amiga computer CAN browse the web. Try that with a Mac Plus.

Cool #2: My 4yr old's computer is more powerful than what *I* had 5 years ago. (AMD64 2.2ghz / 8600GT)

Rated down because someone doesn't like facts.
