AMD launches its fastest desktop chips ever

AMD launched its Phenom II chips, which it calls its fastest processors to date.

In an attempt to gain an advantage in the gaming PC market, Advanced Micro Devices on Thursday launched what it called its "highest-performing CPUs" to date.

Two new quad-core Phenom II processors, aimed at high-end desktop PCs, were announced by AMD at the Consumer Electronics Show in Las Vegas. The chips succeed the Phenom processor the company launched in 2007, and come two days after AMD announced the new Athlon Neo processor for small laptops.

The quad-core Phenom II chips run at speeds up to 3GHz and include 8MB of cache. The chips are capable of even faster clock speeds under certain circumstances. For example, AMD overclocked Phenom II processors to run at up to 4GHz on air-cooled systems, and up to 5GHz on liquid-nitrogen cooling late last year.

Dell is already offering the XPS 625 desktop based on the Phenom II, though pricing information was not immediately available. PC makers HP and Alienware will also offer Phenom II-based desktops later in the year, according to AMD.

AMD is targeting gamers and enthusiasts with the chips, which are also affordable enough for mainstream users looking for a good gaming system, the company said.

AMD's Phenom II X4 940 Black Edition processor, which runs at 3.0GHz, is priced at US$275, while the Phenom II X4 920 processor, which runs at 2.8GHz, is sold for $235.

The Phenom II CPUs are manufactured using a 45-nanometer process, which makes the chips more power efficient than earlier chips.

The new chips are part of AMD's new Dragon platform for desktops, which includes graphics chips, chipsets and CPUs for gaming and media-intensive desktops. The platform includes the ATI Radeon 4800 series graphics cards in addition to the Phenom II.

An interesting feature of the platform is a set of customized controls to boost performance of gaming PCs. Called OverDrive, these controls allow users to ratchet up performance by overclocking the CPUs, which can then be easily returned to a normal speed at the touch of a button.

The platform also includes the ATI Video Converter software, which can convert videos to play on portable entertainment devices, according to AMD.

The platform will initially support DDR2 memory, but faster DDR3 memory support may come in a few months, AMD has said. Compared to DDR2 memory, DDR3 provides a larger bandwidth for quicker data transfers between the CPU and memory in PCs. To support DDR3 memory, AMD will introduce the new AM3 socket for motherboards in the next few months.

High-end chips for gaming systems are also offered by Intel, which launched its Core i7 processor in November.

A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.

Windows 10 for Business / Dell XPS 13

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

Windows 10 / Lenovo Yoga 910

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.
