Relative performance of a few chosen GPUs and CPUs.

As a reference computer I have used a computer based on quite old Xeon E5645 processor and GTX 1060 6GB graphic card.

In each table first and second line is for the same workunit. Third and forth line is for another workunit etc. This way you can compare performance of some graphic cards in relation to GTX 1080.

Amicable Numbers

Recently in Amicable Numbers GTX 1060 6GB can achieve ~17k credits per hour or ~400k per day. Each completed workunit (WU) is rewarded the same number of credits. While usually one WU calculation time is around 1600 seconds, sometimes there are WU that take over 2000s or less than 500s. Relative performance is usually within 10 to 15% of the expected performance based on the official FP32 FLOPS. Almost no AMD cards, as it’s difficult / impossible to find out exact model from the data available on the project’s site. Rather low performance of AMD RX 470 might be due to misconfiguration (I.e CPU starving), overheating or other reasons.

In [email protected] project GTX 1060 6GB takes almost always very close to 1000 seconds to complete the WU. GTX 1060 6GB can achieve ~12k credits per hour or up to ~290k per day (Max RAC ~ 290k). In this small sample Radeon cards either underperformed or outperformed expected times to complete. Very low performance of GTX 760 might be due to misconfiguration (I.e CPU starving), overheating or other reasons. Usually, for GTX cards actual performance is within 10% of expected.

Measured MegaFLOPS are as they appear on the computer spec page on the project site. I assume it is acquired using Whetstone benchmark. Formula BOINC MFLOPS is calculated based on BOINC equation: GigaFLOPS = RAC/200. RATIO is the ratio of the two.

Note that computed data are values per one core per hour, as yoyo WUs run each on one CPU core. Xeon E5645 has 5 cores or 12 virtual cores (threads), thus it can run up to 12 Wus simultaneously. Times are actual CPU times. Rewards are quite scattered. One hour of Xeon E5645 (core) time can be rewarded as little as 24 or as much as 50 credits, in average 36 credits. Twelve threads working at 100% could earn up to 10k credits per day.
