It looks as if the Top GPU models page was updated today. See it here: https://setiathome.berkeley.edu/gpu_list.php I'm looking at the NVIDIA Widows column and am wondering if it is accurate. How can number 10 be the (0.632) GeForce GTX 780 Ti, and number 2 be the (0.817) GeForce GTX 670? The 780 Ti beats the 670 on CUDA cores and memory speed, and is just a bit slower on clock speed. See specs: 780 Ti http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-780-ti/specifications 670 http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-670/specifications Is the 670 really better thanks the 780 Ti for SETI? |

Those scores aren't really rating the cards themselves, I believe, but how much work they do for SETI in aggregate. Perhaps I am wrong on this, and I would appreciate a correction and explanation, if due. |

I'd love to learn more. I appreciate the Top GPU models page but was confused by the ranking since it contradicted the most often quoted performance stats of graphics cards. I'm sure someone here will know why the rankings are the way they are. |

Those scores are allways theoretical. What card is in use doesn`t necessarily mean how efficient it is used. My R9 380 for example has at leat a 50% higher output than the scores would suggest. With each crime and every kindness we birth our future. |

I wasn't aware of the big difference between Nvidia and AMD on vlar files. Al is running 4 WUs at a time. EDIT, that gives him (roughly) 4.8 VLARs per hour and you around 2.6 VLARs per hour. Grant Darwin NT |
