what 95W, HT and Turbo 2/2/3/3 mean in one processor.

Hi All,

I have found description of one processor as follows

Intel® Xeon® Processor X5560 (2.80 GHz, 8MB L3 Cache, 95W, DDR3-1333, HT, Turbo 2/2/3/3)


Of that, what 95W, HT and Turbo 2/2/3/3 mean?

Re: what 95W, HT and Turbo 2/2/3/3 mean in one processor.

95W = 95 Watts, the amount of electrical power consumed (and effectively turned into waste heat) by the processor. Your processor cooling solution must be able to handle at least this much heat.

HT = Hyper Threading. Each CPU core can run two threads of execution in (mostly) parallel. (This is an old trick: it was introduced in 2002.)

"Turbo 2/2/3/3" is related to Intel's Turbo Boost Technology. It lists the number of available processor performance levels when 4, 3, 2 or 1 cores are active, respectively. When only one or two cores are active, those cores can run at slightly higher speed than when 3 or more cores are active. This is to optimize the processor's performance when running non-threaded applications which cannot use more than 1 core at a time.
