After Advanced Micro Devices releases its FX-series microprocessors code-named Zambezi this September, the company will only refresh its lineup of high-end chips sometimes in the first quarter of next year. The first refresh of desktop Bulldozer family will likely precede the launch of Intel Corp.'s code-named Ivy Bridge microprocessors.
Despite of the fact that AMD's initial family of FX-series Bulldozer microprocessors will only include for models (two eight-core versions, one six-core and one quad-core models), AMD will not broaden it until at least the middle of the first quarter of next year, according to a source with knowledge of AMD's confidential plans. In mid-Q1 2012 AMD is projected to introduce four new models, which will broaden the FX lineup to eight stock-keeping units (SKUs).
The initial family of AMD desktop chips based on Bulldozer micro-architecture due in September will include models FX-8150, FX-8100, FX-6100 and FX-4100. The refresh lineup scheduled to arrive in mid-Q1 2011 will contain FX-8170, FX-8120, FX-6120 and FX-4120 models. Exact specifications of the AMD FX chips currently known only from unofficial sources.
Earlier this year it turned out that AMD had to delay commercial launch of its desktop FX-series microprocessors due to insufficient performance of B0 and B1 stepping Zambezi/Bulldozer processors, which could function only at around 2.50GHz/3.50GHz (nominal/turbo) clock-speeds. As a consequence, AMD needed to tune the design of the processor and create B2 stepping of the chip with better clock-speed potential amid similar thermal design power (TDP), which is not a quick process. Looks like the delay of the initial family also made AMD to postpone the refresh.
AMD itself believes that its multi-core Zambezi FX CPUs will allow it to compete head-to-head with Intel's high-end Core i-series "Sandy Bridge" processors that can sell for as much as $300 and more per chip. It should be noted that the refreshed AMD FX "Zambezi" lineup will compete against Intel's Sandy Bridge E as well as Ivy Bridge microprocessors due in late Q4 2011 and March-April, 2012, respectively.
AMD did not comment on the news-story.
