I am absolutely amazed at how much faster my
----------------------------------------i5 4.5 Ghz 8 GB 1600 Mhz RAM Corsair h60 dual 120mm agility 3, 60 GB, 6 Gb/s SSD has stomped my Athlon 2 640 3.00 Ghz 8 GB 1333Mhz stock cooling 7200 RPM caviar blue 500GB Athlon averaged 6-9 for CEP2 working at 100%, and after recently completing my first rig, it is returning valid results around 230-3 hrs!!! Amazed. My efficiency increased from about 90% to about 95% too. Currently maintaining temps around 47-50 C, in both machines. Had to share the news!!

I have one running Linux with 2 gb of ram in the cheapest mobo and case I could find. It eats WCG numbers like a bear eats buns, even at the stock speed. Can you guess when it was fitted?

the comparison of the 2 systems is totaly off ... nothing matches or is close ... from the freqentcys to the disks ... it has no sense. just the ssd itself and it can give a great boost to the timeings.

Cisf: Have a look at the Passmark benchmarks: the Athlon 640 is now slower than even the Sandy Bridge dual-core i3-2100. The first-gen i5-xx laptop CPUs at 2.5Ghz are faster than it, and the i5-2500K 3.30 ghz even at stock speeds, leaves the Athlon in the weeds, SSD, or no SSD. Spot has whacked his/hers up to 4.5 Ghz. The Athlon is toasted.
----------------------------------------Even on my 2GB ram system with dinosaur hard-drive the i5-2500 is a monster cruncher. Goodbye Athlon 640! http://www.cpubenchmark.net/cpu_lookup.php?cpu=AMD+Athlon+II+X4+640 Of course, the Athlon can still do good work for WCG.

Cisf is right.
----------------------------------------A 1.5GHZ diference, an SSD and the i5 RAM is a bit faster than the athlon one. Since he is using CEP2 to compare the two CPU, I think it's the SSD that makes the difference. And given the price difference between the Athlon($99.99 on amazon.com) and an i5 2500K($214.95 on amazon.com) with both 95w TDP I think the Athlon is worthier than the I5. Not to mention he only gains a 5% improvement with a SSD which is very expensive. The 5% improvement just ain't worth in my opinion. Not to mention that the 1.5GHZ overclock is probably draining a lot of power. PS: I'm an AMD guy now. To me AMD is the best. If you think my opinion is biased let me know  Edit: My example: I have a AMD Sempron 145 2.8GHZ unlocked(ie. now a dual-core) and overclocked at 3.7 GHZ. It draws 88 watts and finishes an HCC task in 1 hour and 15 minutes. My RAC has jumped from 100 or so to over 350. I had a Pentium 4 which was slow I know, but the Sempron is a single-core too with another disabled. Anyway here are the BOINC benchmarks: 30-12-2011 11:53:23 3776 floating point MIPS (Whetstone) per CPU 30-12-2011 11:53:23 8066 integer MIPS (Dhrystone) per CPU It's very nice for a CPU that costs around $30 I would like to see the boinc benchmark of 5pot's i5 for comparison.  - 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 [Edit 8 times, last edit by Falconet at Dec 30, 2011 11:58:56 AM] |

Yes these are very good FP figures for the Athlon, about the same as the i5-2500 (unclocked) But, if it is important, the Dhrystone integer b/mark for the stock i5-2500 is 2.6 times better than that of the Athlon (8066)at 216,38 mips.

The real comparison from AMD in my opinion is the Phenom II X6 cpu's, which are on par with the 2500k, yet still cost less than the the 2500k.
----------------------------------------Even if the 2500k is 50% faster per core than the Phenom II, the X6 has 2 extra cores to make up the difference in points/runtime/wu since it has 50% more cores Don't get me wrong the i5/i7 systems are great...I have a few myself. Its just that when the 1055t went on sale for $120 bucks recently, the price/performance ratio was unbeatable.  [Edit 2 times, last edit by ryan222h at Dec 30, 2011 2:32:58 PM] |

Let me say that I knew it would be faster, but like I said was taken aback by how much faster.
Now, I got the cpu for 180 through micro center, and a 1100t or 1090t black edition was 160. Next, the SSD was cost only 90 since there was a $20 rebate, and HDD are just as expensive as that currently. The amount of space is irrelevant, since I have plenty of extra TB laying around. Finally, the power draw is something I will be looking at shortly so I will hopefully find a "sweet spot" for points/watts. Happy crunching and Happy New Year!! |

I am absolutely amazed at how much faster my Now all you have to do is buy 3 more of them with same make/model HDs and then configure them so that the BOINC data rides not on the system drive but on dedicated data drives configured as:i5 4.5 Ghz 8 GB 1600 Mhz RAM Corsair h60 dual 120mm agility 3, 60 GB, 6 Gb/s SSD Single HD RAID 1 RAID 5 RAID 10 Set 'em all up so that they run CEP2 on 75% of cores, let 'em run for a week, and let me know how many results each HD configuration returns so that I don't have to stop crunchin' to find out.  |
