He is running W7 64 bits. Maybe the 80% cap in CPU usage helding him back?
----------------------------------------BitWalker, rather than setting CPU usage at 80% you should try throttle. It allows you to choose a maximum temperature for the CPU and it is more efficient for crunching. http://efmer.eu/boinc/ AMD Ryzen 5 1600AF 6C/12T 3.2 GHz - 85W AMD Ryzen 5 2500U 4C/8T 2.0 GHz - 28W AMD Ryzen 7 7730U 8C/16T 3.0 GHz |

Oh, many thanks for this hint - so simple and effective ! I only forgotten that there is this feature in the BOINC client... :) Core i7 4700 --------------------------------------------- 3783 floating point MIPS (Whetstone) per CPU 10828 integer MIPS (Dhrystone) per CPU AMD FX8350 --------------------------------------------- 1502 floating point MIPS (Whetstone) per CPU 7937 integer MIPS (Dhrystone) per CPU ... indeed, that explains the big difference! Okay, on the other hand you can get the FX8350 for the half price of a i7 4700k Cheers, BitWalker My main desktop has an i7 3770, it seems you have an i7 4770k. So I was curious to compare my benchmark to yours, and here's what I got: 3569 floating point MIPS (Whetstone) per CPU 9378 integer MIPS (Dhrystone) per CPU Your cpu temps are on the high side though not in the "danger zone". Are you using the heatsink fans that came with the processors or are they store bought computers? I always like to use aftermarket cpu coolers, usually Cooler Masters with Artic Silver 5 thermal grease. My computer runs 24/7 at 100% cpu time, and stays between 54-57C. It is nice to see your real world results with FX 8350, I was considering building a new computer with a 8320 for a long time (tried to justify it a dozen times!). But the lower performance and higher power consumption do not make AMD a better value than Intel, plus the FX do not have integrated graphics, so you're looking at least another $40 for a low end graphics card. |

Hi I just obtain data about my AMD Athon II x4 645 , 45 n downloaded at 2.6Mhz 4Giga RAM Win 7 64 and data are quite highter that FX8350 :
2124 flooting Whetstone 6475integer Dhrystone BOINC Manager 7.2.3.3 64 bit I'm thinking to change my system with a new AMD Kaveri APU or FX 8 core ...What do to think could be better? |

robertobit,
----------------------------------------The best Kaveri APU is a 4 core CPU+GPU in a single chip. I'm not sure how faster the CPU part is when comparing to the Trinity APU (2012) or Richland APU (2013). The FX CPU is a good one although some people complain about a somewhat high power usage. If you go with the FX, buy the FX-8320 rather than the 8350 since you can just overclock a bit to match the speeds of the 8350 and save yourself quite a lot of money. Personnaly, I would get a FX-6300. Cheaper, uses less power and has just 2 cores less. Btw, my Sempron 145 2.8 GHZ unlocked to Athlon II X2 4450e overclocked to 3.5 GHZ (1.4 voltage): 11-02-2014 11:11:09 | | 3514 floating point MIPS (Whetstone) per CPU 11-02-2014 11:11:09 | | 7339 integer MIPS (Dhrystone) per CPU AMD Ryzen 5 1600AF 6C/12T 3.2 GHz - 85W AMD Ryzen 5 2500U 4C/8T 2.0 GHz - 28W AMD Ryzen 7 7730U 8C/16T 3.0 GHz |

Okay, on the other hand you can get the FX8350 for the half price of a i7 4700k Cheers, BitWalker Those FX-8350 figures seem awfully low... I've seem better benchmarks of that CPU... My Phenom II X3 720 BE at 2.8 GHZ (stock) has this: 3368 floating point MIPS (Whetstone) per CPU 6952 integer MIPS (Dhrystone) per CPU I managed to get it to 3.5GHZ once and it reached 3900 (or so) floating point and 11000 (or so) Integer but the PSU was complaining and I don't to use too much power. Temps are at 47 celsius with stock AMD cooler. Are you sure that the motherboard/windows isn't throtling the CPU? Btw, FAAV runs a lot faster on Linux 64 bits. 05/01/2014 10:24:50 | | Benchmark results: Check the m/b has the latest bios and drivers for the chipset within Windows. Also are you running 32 bit or 64 bit Windows? Also, I would agree that the temperatures are high, mine run flat out at 55C although they are watercooled. I would expect your's to run around 10C hotter on air. They will be effected by the ambient temp in the room they are located in. Let us konw how you get on etc... My FX-8350 gives: Measured floating point speed 3152.42 million ops/sec Measured integer speed 11557 million ops/sec Win7-64; 4214 MHz out of the box; BOINC 7.2.33; Thermal Margin 23.9  crunching, crunching, crunching.
