briesmith Posted August 23, 2011 Share Posted August 23, 2011 Speccy reports the following Intel Core 2 Duo E7500 Cores 2 Threads 2 Name Intel Core 2 Duo E7500 Code Name Wolfdale Package Socket 775 LGA Technology 45nm Specification Intel® Core2 Duo CPU E7500 @ 2.93GHz Family 6 Extended Family 6 Model 7 Extended Model 17 Stepping A Revision R0 Instructions MMX, SSE, SSE2, SSE3, SSSE3, SSE4.1, Intel 64 Virtualization Unsupported Hyperthreading Not supported Fan Speed 1997 RPM Bus Speed 266.0 MHz Rated Bus Speed 1064.1 MHz Stock Core Speed 2933 MHz Stock Bus Speed 266 MHz Average Temperature 39 ?C Caches L1 Data Cache Size 2 x 32 KBytes L1 Instructions Cache Size 2 x 32 KBytes L2 Unified Cache Size 3072 KBytes Core 0 Core Speed 1596.1 MHz Multiplier x 6.0 Bus Speed 266.0 MHz Rated Bus Speed 1064.1 MHz Temperature 39 ?C Thread 1 APIC ID 0 Core 1 Core Speed 2926.3 MHz Multiplier x 6.0 Bus Speed 266.0 MHz Rated Bus Speed 1064.1 MHz Temperature 39 ?C Thread 1 APIC ID 1 Which is puzzling (to me anyway) as I thought both cores ran at the same speed.

Super Fast Posted August 31, 2011 Share Posted August 31, 2011 If u are using a flipchip processor that can operate at a range of speeds depending on application demand, I would assume that each core can be cranked higher or lower individually of each other, according to need. Anyone else have another theory? Link to comment Share on other sites More sharing options...
briesmith Posted August 31, 2011 Author Share Posted August 31, 2011 Is this a flip chip processor?

kroozer Posted August 31, 2011 Share Posted August 31, 2011 . . . I thought both cores ran at the same speed. So have I. I've searched since 23 August and can't find anything. If you ever find an answer, please post it here. Link to comment Share on other sites More sharing options...
Alan_B Posted August 31, 2011 Share Posted August 31, 2011 According to Heisenberg's Uncertainty Principle it is impossible to know both the exact position and the exact velocity of an object at the same time. http://www.bbc.co.uk/dna/h2g2/A408638 What is impossible to determine with one object does not become easier with two objects in the same instant ! ! I strongly suspect that the two cores are measured at different times, and wonder if some Processor Clocking Control has kicked in after measuring one core before measuring the other.

briesmith Posted August 31, 2011 Author Share Posted August 31, 2011 I am not certain I've ever had a Heisenberg system. I thought processors worked at a speed determined by the clock crystal and I hadn't appreciated they are load sensitive. My interest has been piqued by this becasue if the processors only work at the quoted speed some of the time and only in certain circumstances then what exactly are we buying/being sold?
