...and to get back on topic, 200MIPS/W
i7-2600K, Ubuntu 11.04-x64: 4160/17567 for 166W crunching on all 8 threads. So that's 4160X8 for 166W at the wall (33280/166W=200MIPS/W). |

4160X4 for 166W at the wall (16640/166W=100MIPS/W).
----------------------------------------Only 4 cores on a http://ark.intel.com/products/52214/Intel-Cor...cessor-(8M-Cache-3_40-GHz) The 8 threads run on 4 cores The benchmark and real crunching potential is core based With Hyperthreading it shares 1 core with 2 threads so each thread only has half the time on the processor Only the application is bluffed into thinking it had the processor for the full time Great for run "time" but not for actual work being done Them's the rules  ...and the cost of Electricity is very much the raison d'etre of the thread If we can do more with less the WCG benefits, our pockets benefit and we use less resources Everybody wins   |

"and now it is more than the double as it was 20 years ago"
----------------------------------------Hi Hypernova With our choice of suppliers it's rapidly approaching double what it was in the UK in just 7 years  You can't beat the price of freedom |

On the performance per watt theme: http://hardware.slashdot.org/story/11/09/13/2...w-Introducing-Koomeys-Law
----------------------------------------"MIT Technology review reports on a recent paper by Stanford professor Dr. Jon Koomey, which claims to show that the energy efficiency of computing doubles every 1.5 years. Note that efficiency is considered in terms of a fixed computing load, a point soon to be lost on the mainstream press. Also interesting is a graph in a related blog post that really highlights the meaning of the 'fixed computing load' assumption by plotting computations per kWh vs. time. An early hobbyist computer, the Altair 8800 sits right near the Cray-1 supercomputer of the same era."  Distributed computing volunteer since September 27, 2000 |

Boinc benchmarks the CPU; that's all the cores and all the 'threads' at the same time, so it really is 4160 X8.
If I limit the threads used to 6 it benches 6 threads simultaneously (and gets higher bench numbers). If I bench 1 or 2 'threads' they will be higher again; this is to do with the turbo mechanism - the fewer threads in use, the higher they clock in turbo mode (3.5GHz with all 8 threads, 3.8GHz with one). It's just a fact that these CPU's do way more work than any AMD desktop CPU, and until BD is actually released that will remain the case. So far it's BD server CPU's and only to OEM's - ie Not For Sale. AMD is even blocking benchmarks. I think that by the time you actually have an AMD BD there will be newer SB desktop chips out. So any would be advantage will be lost. PS. The number of operations per cycle is just as important as frequency. When OC'ing they usually nobble everything else to maximize frequency. Many high clocks are fairly useless. So highest benchmarks are more important. |

This will have to do. I did not have time to wait until Bulldozer came out and cannot afford a core i7. This is 125 watts TDP, probably close to that at 100%.

So the forthcoming Bulldozer CPU's will have 2 'Cores' per Module
 That sounds very much like 2 threads per Core! Sounds like AMD are attempting to rename Core to Module  Eh, not buying that... |

Asia.
----------------------------------------That's a fair point and only time will tell That said only the FPU is shared between the 2 cores and the FPU is twice the size of that on my Phenom II and separable into 2 128 bit FPU's Scheduling will be everything and every now and again you will have the possibility to crank the handle just once and get 2 fpu results At least it's not just bluffing like Intel's HT I fully expect the 4 modules of an 8 core Bulldozer to churn out more completed work units for the same TDP as my 1055T 6 Core Phenom II 95W TDP Looking forward to finding out this side of Christmas.... hopefully |
