Hello
Is anyone crunching on a AMD FX8120. Curious as it has more cores and Im thinking of getting one if it does a good job. Any issues ? How does the AMD A8-3850 go at crunching here at WCG. Thanks Peter |

Thanks Peter I would do some homework before buying any of the new bulldozer CPUs to use as a cruncher. Their power consumption is too high IMHO. Especially if you overclock them. Google is your friend.

I'm sure the new AMD CPU's do a decent job at crunching. Intel CPU's are definitely better at performance per watt and pure performance, but if you have your heart set on AMD then I would say go for it.
----------------------------------------In the end, any contribution to our cause is a good one, so pick whichever CPU suits your desires best... :)  |

whichever cpu you plan on using make sure you install a water-cooled cpu fan & radiator, a helluva lot cheaper than replacing a burnt out chip

Hello Is anyone crunching on a AMD FX8120. Curious as it has more cores and Im thinking of getting one if it does a good job. Any issues ? How does the AMD A8-3850 go at crunching here at WCG. Thanks Peter Hi Peter. There is a 8120 running on Docking@Home, I found it looking for someone else that asked the same thing as you. As Docking has a fairly fixed task size they are all close in run times and the 8120 is slower then my (stock) 1055T by around an hour per task, so sorry to say i won't be getting one until they can get them running much faster/better. If you can afford an intel i7 i'd get that otherwise get a x6 1090T or 1100T there much faster. There is a thread over at Docking about it if you want a read. hope it helps.

Hmm, going by Docking@home, the 8120 seems to use roughly 15700 seconds/task while your 1055T uses roughly 11700 seconds/task. Taking into account the 8120 runs 8 tasks at once and your 1055T runs 6 tasks at once, this means the difference between these two cpu's is only 0.6 % in daily production. So based solely on crunching-performance on Docking@home, neither cpu has really any advantage. Based on WCG on the other hand, if assumes WCG-projects performs similarly, the 8120 produces 33 % more cpu-time per day and means it's faster at getting a badge. Then it comes to other considerations like power-usage I've no idea how much either of them uses. Then it comes to cpu-cost on the other hand the 8120 does have a disadvantage.

Or a cpu fan meant for overclocked gaming. Problem with those is they are quite large although very impressive looking.
Plus the case is also important. FYI there are water cooling kits that are easy to install and you don't need to change the water out of them. There are a number of sites that custom build pcs and often they have deals so that they cost as much as buying all the stuff separate with the bonus of several years warranty and being professionally put together. |

I would look carefully at the power usage issue. While I prefer AMD(typed on a 1055T), the current generation of Intel processors appear to have superior efficiency. Re: AMD A8-3850 & AMD FX-8120 processors whichever cpu you plan on using make sure you install a water-cooled cpu fan & radiator, a helluva lot cheaper than replacing a burnt out chip I have considered that but what is the wattage on those things? When you are running 24/7 things like that matter. |

When you are running 24/7 things like that matter. The question is not the wattage that the cpu cooler itself takes, but how much additional wattage that the CPU is using when overclocked, that you need a water cooler to cool it? To put it another way, I think if you need a water cooler to cool your system, it must be using enormous amounts of electric. The exception here is if you are using water cooling to keep your system cool for reliability instead of extreme overclocking |

It will shut itself down before it burns out. Chips get burned out by excessive voltage placed on them by overenthusiastic overclockers :) |
