Bite Communications and Text 100 will work on a joint brief across the EMEA region in a move to realign AMD's global PR.
The agencies will handle AMD's comms in the UK, France and Germany, focusing on consumer PR, media relations and analyst relations.
Bite already works with AMD in the US, and this helped Next Fifteen win the brief.
'We're looking to better globally align our organisation,' said Jon Carvill, senior manager for public relations for EMEA at AMD. 'North America and EMEA are where we invest most heavily in press relations and this was a chance to consolidate our activities.'
Under Waggener Edstrom the account was valued at £250,000 per annum. It is now believed to be worth up to seven figures. The Next Fifteen agencies pitched against tech specialist Pleon and global firm Ketchum, which also handle part of AMD's brief in the US.
'One thing that impressed AMD was our methodology, where we have different heads for digital media and broadcasting,' said Nick Rappolt, head of planning at Bite. 'We will be looking at campaigns that can be run across Europe on multimedia platforms.'
