PC World escapes punishment over chip ads
OK to say Core 2 Duo is "twice as fast"

PC World has escaped punishment from the UK's advertising watchdog after one of its adverts appeared to suggest Intel's dual-core processors performed twice as quickly as single-core processors.

A national press advert for the retailer featured laptops and PCs using Intel's dual-core Core 2 Duo processors. Part of the ad read: "Core 2 Duo twice as fast… Intel Centrino Duo mobile technology with Core 2 Duo processor."

The person who complained to the Advertising Standards Authority (ASA), whose name was not revealed, suggested the claim "twice as fast" mistakenly implied the Core 2 Duo would always be twice as fast as a single-core processor. The critic said they understood that, because of shared hardware components, the Core 2 Duo would be no more than 1.7 times faster than a single-core processor.

In response to the complaint, PC World said the laptop advertised used Intel Core 2 Duo and Centrino technology. The retailer pointed out that the text "twice as fast" was linked to a footnote that explained the claim was based on benchmarking against the performance of previous generation Intel Centrino chipset technology, and readers could learn more by visiting the Intel website.

The footnote in the advert read: "Based on multitasking benchmarking against previous-generation Centrino. See www.intel.com for details."

PC World said it therefore disagreed with the assertion that the advert implied Core 2 Duo technology would always be twice as fast as a single-core processor because it was not being compared with a single-core processor.

The retailer said the claim "twice as fast" originated from Intel itself and it sent the ASA a sample of benchmarking data. It argued it was reasonable to compare the performance of the current technology against that of the product's well-known and immediate predecessor. PC World said it was not currently using the claim but would like to do so in the future.

In its ruling, the ASA rejected the complaint and said no further action was needed. It noted the claim's footnote made it clear the statement referred to the performance of Core 2 Duo technology against previous-generation Centrino technology.

The ASA said: "We acknowledged that the ad made clear the basis for the 'twice as fast' claim and where readers could find out more information about that. We concluded that the ad was unlikely to mislead."

It is not the first time PC World has found itself the subject of ASA complaints. Previous disputes have covered issues such as laptop sale prices and wireless-access technology speeds but this is the first time dual-core processors have been involved.
