Apple unveiled an external trackpad for iMac personal computers
Owners of Apple notebooks have long appreciated the large glass touchpad with Multi-touch gesture support. What's more, many people don't even think about buying an additional mouse - the touchpad is quite enough for any task. Apple has decided to extend the touchpad's range of users by introducing the Magic Trackpad, an aluminum Apple Keyboard-style touchpad designed for the latest Apple Keyboard releases. You can already buy this strange device for $70.

Together with the magic touchpad, Apple has upgraded its iMac and Mac Pro computers with new processors from the latest Intel lineup and state-of-the-art ATI Radeon HD 5000 graphics cards. The developer also introduced a giant 27-inch Cinema Display with IPS panel for $1000.

New ATI Radeon graphics cards - at the end of October?
We have another (already the third) confirmation that AMD will unveil new graphics cards at the end of the year - this time the information was published by our colleagues from Heise.de. They say the information comes from quite reliable sources. It is rumored that the first and most powerful models of ATI Radeon HD 6000 will be presented from 15 to 29 of October 2010.

The line of chips, codenamed Southern Islands, will improve overall performance levels, but are unlikely to surprise the sophisticated public with any entirely new features. Probably, the 6000-series top models are meant to beat the flagship single-chip graphics cards based on NVIDIA Fermi graphics chip - the Californian developer has to solve production problems, and then AMD will have no trumps up its sleeve. Let's see if everyone's predictions come true.

Intel announced an optical bus
Modern computer components are connected and communicate with each other with copper-based wires, but that could change in the not-too-distant future - Intel has shown a working prototype of a new optical bus, which uses light to transfer data bits. The new bus allows data to be transmitted over more or less long distances at speeds of up to 50 Gbit/s.

Intel's engineers are already working on improvements to get up to 1 Tbps which would be enough to copy the entire contents of an average laptop in a second (if only there was a hard drive which could do the same speed). It is emphasized that the announced research goes hand in hand with the development of the Light Peak interface.

HP installs Fermi-based Quadro in notebook PC
We are sincerely puzzled who uses laptops in professional work, but nevertheless. HP announced an extremely powerful mobile system with NVIDIA Quadro 5000M graphics card based on Fermi graphics chip (320 shaders, 2 GB of native memory, support for DirectX 11 and OpenGL 4.1, plus a lot of tweaks for professional work with graphics).

The fancy chip will be installed in the 8740w EliteBook with a 17-inch display and a price tag starting at $3,000. Also on the agenda is a armful of the most powerful mobile components and a miniature nuclear power plant in addition. And a variant with a bicycle generator for those who are poorer.

Intel to limit Sandy Bridge overclocking
If we believe the information published by colleagues from HKEPC.com, Intel will trim the overclocking features of future Sandy Bridge codenamed processors. According to rumors, the manufacturer wants to simplify the design of mainstream platforms to reduce production costs and at the same time force enthusiasts to buy more expensive motherboards and more powerful Sandy Bridge E processors.

Judging by the published HKEPC slides, the company is going to integrate the frequency generator directly into the chipset, codenamed Cougar Point - the generator will simultaneously set the frequency for all buses in use. Therefore, changing frequency of the processor will entail changing frequencies of other system components, which is highly undesirable. Chipsets for more powerful Sandy Bridge E processors, in turn, use external frequency generators. I think Intel just gave AMD a reason to make fun of it via advertisement.
