CPU Buying Guide


AMD Phenom

Taking over from the Athlon will be the AMD Phenom, which, at the time of writing, was still not available on the market. The Phenom will be manufactured using a 65-nanometre process, so it will be much smaller and should run cooler than the Athlon CPUs and it will be available in various configurations. For example, there will be dual-core, tri-core and quad-core versions of the Phenom, which should suit a wide range of budgets and needs. For enthusiasts, the Phenom Quad-FX platform will allow two quad-core Phenom CPUs to be plugged in to one motherboard, which will provide eight-core (or octa-core) computing.


What is Cool 'n' Quiet?

Cool and Quiet

Cool 'n' Quiet is AMD's proprietary CPU throttling technology that dynamically changes the CPU multiplier and voltage depending on the workload you're placing on it. This means that if you're merely pottering around the web, it'll scale back the processor speed and power consumption, but if you then launch into some heavy duty video encoding, it'll ramp back up. AMD claims that it's capable of reducing power consumption by up to 40 watts. From an end-user standpoint, it's very similar to Intel's mobile Speedstep technology, although AMD's chosen to implement it on desktop processors. AMD's mobile equivalent for Cool 'n' Quiet, which more closely mirrors Intel's Speedstep, is called AMD PowerNow!.


What is Enhanced Virus Protection?

Enhanced Virus Protection is a security technology implemented in AMD's Athlon 64/FX lines, and some of its Sempron lines. It works in concert with Windows XP Service Pack 2 to stop certain applications from running into a situation where by overflowing memory buffers, system security is compromised.


What is HyperTransport?

HyperTransport is a technology originally known as Lightning Data Transport (LDT), jointly developed by AMD and other partner companies. It's an extremely high-speed system bus that's currently used by AMD and other HyperTransport Consortium members, such as Apple. Within AMD's architectures, hypertransport provides a link running at up to 2600MHz, capable of shuffling up to 20GB/sec between the processor and the main system.

HP OfficeJet Pro 8730

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.

HP OfficeJet Pro 8730

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.

As a freelance writer who is always on the go, I like my technology to be both efficient and effective so I can do my job well. The HP OfficeJet Pro 8730 Inkjet Printer ticks all the boxes in terms of form factor, performance and user interface.

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.

Windows 10 / HP Spectre x360

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!

Mark Escubio

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.
