AMD brings Barcelona to the world

By Justin Mann on September 10, 2007, 10:57 AM
After over a year of anticipation, numerous delays, lots of propaganda from different sides and much more, AMD has finally brought the next generation of their CPU architecture to the table. In the form of a native quad-core Opteron, AMD's long-awaited Barcelona has finally arrived.

Representing change in many areas, AMD's new core offers promises of many significant advancements, from power reduction to performance boosts and a host of features aimed at the high end. Since the first CPUs to market are Opterons, there's little to be said regarding performance. Even the reviews that came out this week are sparse and don't shed a whole lot of light. One very interesting thing of note, however, was AMD's introduction of Average CPU Power. ACP isn't a technology, but a new standard to rate the power consumption of a processor

The idea behind this change is that older power rating methods don't give an accurate depiction of the actual amount of power a CPU will use in any given environment. Whether or not the ACP figures are accurate still remains to be seen, but they are happy to announce it:

AMD also today introduced the Average CPU Power (ACP) metric, which represents processor power usage, including cores, integrated memory controller, and HyperTransport™ technology links, while running a suite of typical and relevant commercially useful high utilization workloads to be more indicative of the power consumption that end-users can expect. ACP is a useful metric for data center operators when estimating power budgets to size their datacenters. AMD will continue to provide thermal design power (TDP) specifications to platform designers in AMD power and thermal datasheets.
The release of Barcelona will bring answers to many questions over the following months. Will AMD be able to continue growth of the Opteron over the Xeon? Are they too late to market to reclaim what has been lost to Intel? Will their next line of desktop CPUs launch on time, and will they be able to cope with Intel?

A lot of questions, though after so many months of waiting I am glad to see AMD finally got this out the door. The full press release is on AMD's site.

Okay so honestly.....since power consumption is the only selling point here.How many of you guys build your PC around power consumption?I have built rigs for about 8 years now, and that is the least of my worries. I want something that is going to kick some serious processes and video frames. Slap a fat power supply in and roll.....

Barcelona is an enterprise focused product, where power consumption does matter and make a difference. That said, AMD will use the same platform for future desktop and mobile processors, and the way things stand today it's better to have such an architecture that consume less power, offers good performance, and then scale up on it. That's more or less what Intel was able to do with Core CPUs.

How do you see power consumption as the only selling point? The press release repeatedly mentions how this is the first "native" quad core processor and the performance boost inherited from the new architecture design.

Every tech website has panned this processor its got IPC equal to or lower than clovertown not to mention penryn is on the way and not to mention they arent even taking into account that AMD's highest end processor is competing and losing to intel's mainstream/low end "non native" quadcore........Power consumption is THE ONLY SELLING POINT!!!

Your internet insults degrade your opinion.So, if I currently have a server farm of 4 way Opteron based servers and am looking to upgrade performance. I shouldn't consider the new backwards compatible Barcelona chips? I would only be interested in saving electricity by doing so? At least we know your statement is verifiable by the great references you included. Oh wait, thats right, your statement isn't backed up and is actually baseless. I'm at a loss to find one tech site that verifies your statement but I can find one that refutes it. [url=
/]Tech Ware Labs[/url] claims that "...the overall performance advantage of the Barcelona over the Xeon is about 20% per clock". Please try and grow up a bit before you start slinging insults and spreading FUD.[Edited by PanicX on 2007-09-12 14:51:27]
