AMD upgrades dual-core Opteron chip to 3GHz

AMD has begun shipping two 3GHz versions of its dual-core Opteron chip to server vendors

AMD has begun shipping two 3GHz versions of its dual-core Opteron chip to server vendors, continuing a battle over multicore processing power with Intel, the company said.

AMD planned to begin full volume shipments by early May of the new Opteron 2222 SE chip for two-processor servers and the 8222 SE chip for eight-processor servers, director of Opteron marketing, Patrick Patla, said.

The new chips are similar to AMD's previous top-shelf dual-core chip, but run as fast as 3GHz instead of 2.8GHz for customers with general-purpose servers and workstations that need the extra speed to handle larger databases or more complex technical computing tasks.

The company did not say which vendors plan to release computers using the new chips, but vendors using the current Opteron chips include Dell and HP.

AMD plans to design only one more version of this processor family, releasing a 3.2GHz dual-core Opteron chip by the fourth quarter, before committing entirely to a quad-core Opteron design called Barcelona, due to reach markets in the middle of 2007, Patla said. AMD would continue to produce those final dual-core Opteron chip designs for several years to come.

When used with multithreaded software, multicore chips can speed computing jobs by breaking them into smaller parts and calculating results in parallel. That approach can produce great results for high-end video games, but is more frequently used in servers than desktops.

Intel also planned to push its dual-core chips above 3GHz by the end of 2007, using its next-generation Penryn chip design to speed up certain chips by shrinking their transistor dimensions from 65 nanometers (nm) to 45nm, the company said last Wednesday. In comparison, Barcelona will be AMD's first server chip with features smaller than 90nm.

Even so, the new Opteron chips beat Intel's fastest dual-core Woodcrest processors in several benchmarks, AMD claimed in a full-page newspaper ad that ran this week.

In return, Intel spokesperson, Christine Dotts, replied with a single word: "Rubbish". She questioned AMD's benchmarking conditions and said that customers seeking improved server speed could buy Intel's quad-core chips for the same price as AMD's dual-core chips. Intel launched its Clovertown quad-core Xeon processor in November.

"We'll let the hundreds of reviewers and independent benchmarks speak on our behalf," Dotts said.

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.

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!

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.
