Very fast cpu. Cost and performance leaves intel in the dust. For normal, single threaded apps, the price/performance is probably better.Wait, the other person said the i7 was more powerful and also used less energy... However, with an i7-2600 (or K), you'll be running 8 WCG tasks at a time versus 6 for the X6. You'll be using around 25% fewer watts to run 33% more concurrent tasks. You make the call.[Edit 2 times, last edit by pirogue at Aug 18, 2011 1:06:46 PM] |

I would say stay away from the x6 1100t because it is outdated technology, 45nm on an even older architecture
----------------------------------------Even AMD now has an x4 cpu (a8 3850) which is nearly as powerful as the x6 1100t with a lower tdp of 100 watts. And its mcuh cheaper than the 1100t, at least in the U.S. @ around $139  |

And its mcuh cheaper than the 1100t, at least in the U.S. @ around $139 The a8 3850 is an interesting animal. It has only 4 CPU cores and does not hyperthread, but it has a 400-core AMD GPU built in. Thus the TDP and price cover both CPU and GPU. The GPU won't currently help with any WCG computing, however. It could probably be used on the few BOINC projects that can run on single-precision AMD/ATI cards. (I've successfully run Collatz and MooWrapper on the GPU included in the AMD E-350.)  |

Intel Core i7-2600K @ 3.40GHz Us $427,31** ??? Where did you get that price? http://www.newegg.com/Product/ProductList.asp...&Description=i7-2600k If you shop around you can find them on sale for $299 or so. Check for a Microcenter nearby. If you search the overclocking websites you can buy them from bin testers for $260 or less. The 2600k can also be easily overclocked and it will far out perform any X6 using far less power.

This AMD vs. Intel debate is going into far more detail than the OP was interested in and there never can be an ultimately "right" answer. Yes, Intel is stronger, and more energy efficient with smaller channels, but you pay a lot more for that newer technology.
----------------------------------------It's the same debate with any computer purchase. Do you want bleeding edge and pay for it with a steep depreciation curve, or do you want almost as new at a heavily discounted price and similar end results? Myself, I just yesterday installed my latest Phenom 2 1100. Since I had a case lying about; I got the CPU, 4GB ram, motherboard, and one of those fancy copper tube coolers all for US $292.90 delivered to my door. I can't touch an Intel i7 CPU alone for that price.  Distributed computing volunteer since September 27, 2000 |

Does a completed "Valid" work unit care if it was processed on an Intel or AMD processor?

Yes, Intel is stronger, and more energy efficient with smaller channels, but you pay a lot more for that newer technology. Exactly.He didn't ask for the cheapest possible solution to crunch a few WUs. He didn't ask about depreciation. He's not running cinebench or doing other benchmarks. He was asking for input on building a complete PC for around $600 AUD, using his preferred vendor, to crunch WCG. I presumed he wanted to a) crunch as many WUs as possible and b) use as little power as possible, for his $600 AUD. |

I was looking at the AMD Phenom II X6 1100T (3.3GHz) CPU which is only $213.00 AUD which is awesome. I was wondering how is the performance of the above CPU in all of the WCG projects such as Help Conquer Cancer? Can someone build me a complete pc using the above cpu for under $600 from that site? A little over is ok. I'd like the pc to be as low on power as possible, but still highly effective in crunching numbers on the official WCG projects.! Since Piroque brought us back to the original question, I'll answer that specifically since I have exactly the build you were asking for and I run exclusively HCC. It runs six units concurrently and they run anywhere from 1.05 to 1.51 hours. The size of the units vary somewhat. I also have another system with and i7 Q720, it runs 8 units concurrently anywhere from 3.2 to 4.25 hours. Unfortunately, I don't have exact even matches to compare apples to oranges, (or at least as close as possible considering different brands) the i7 is a lower clock speed than the Phenom. Now we get into statistics, which is other people's strong suit. My abilities lie in remembering obscure information. The best estimates on hyperthread performance on BOINC is about a 15% gain in the amount of completed work for a given time period. So you're comparing 6 cores running at full speed or 4 cores (8 threads) running slightly above half (57.5%). Unless my math fails me, the AMD gives you more performance for your time at a much lower cost and a slightly higher electricity consumption. 6*100 = 600; 8*57.5 = 460 or 4*115 = 460 The choice is yours (always has been) but I wanted to give you the best possible information with which to work. edited for grammar and clarity Distributed computing volunteer since September 27, 2000 [Edit 2 times, last edit by KWSN - A Shrubbery at Aug 18, 2011 8:24:18 PM] |

Unfortunately you can't be generic about the HT gain, or lack of it; % gain varies considerably between different CPU's, over several generations. The original HT processors were poor compared to the most recent (Sandy Bridge). In between came the i7-900 and i7-800 series CPU's (and a few others).
The last SB I bought was an i7-2600 and it cost about £150. Well worth it, especially as it consumes around 65W, slightly over half of my i7-920 @ 3GHz, but the SB does more work, making it about twice as power efficient per performance. |
