AMD Releases Six-Core CPU, 890FX Chipset

Intel released their own six-core CPUs just a few weeks ago, and smaller market rival AMD today came out with their own efforts. Coming in at a fraction of the price of Intel’s effort, it remains to be seen which processor users will pick.

The new CPUs are an update to the quad-core Phenom II X6 CPUs that AMD released last year. The six-core chips are essentially the four-core CPUs with an extra two cores. Not too much was changed in the basic silicon of the processors, save for the additional two cores themselves as well as the addition of AMD’s Turbo Core functionality.

Processor Model Clock Speed System Bus Socket Manufacturing L2 Cache
PII X6 1090T 3.2GHz 4.0GT/s AM3 45nm SOI 3MB
PII X6 1055T 2.8GHz 4.0GT/s AM3 45nm SOI 3MB

AMD Turbo Core is the CPU maker’s answer to Intel’s Turbo Boost, which upclocks core speeds when parts of the processor are being under-utilized. In AMD’s case, when the CPU recognizes that three cores aren’t being used, it will boost the other three cores by 4-500MHz, from 3.2GHz to 3.6GHz or 2.8GHz to 3.3GHz.

Manufacturing L2 Cache L3 Cache TDP Voltage Max Temp
45nm SOI 3MB 6MB 125W 1.125-1.40V 62°C
45nm SOI 3MB 6MB 125W 1.125-1.40V 62°C

While many were expecting AMD’s CPUs to come in for several hundred dollars, AMD decided to compete on price, like they’ve been trying to for the past several years. The 1090T has an MSRP of $279.99, and its slightly slower sibling 1055T has an MSRP of $199.99. The new processors are socket AM3 chips but come with AM2+ backwards compatibility, and AMD claims that 160 motherboards are ready for use with the new chips today, with BIOS updates where required.
