oclHashcat running on the new AMD hd7970 - atom - 01-11-2012 Welcome! The first thing I noticed, one could call it "a problem", is, that there is no linux driver available. So, instead of worrying I directly went to my Win7/64 box and attached it on there. After that, I installed the "amd_radeon_hd7900_win7_64.exe" special driver from AMD page. Installing the driver worked without any problems (had catalyst 11.12 installed before). In the following steps I am using oclHashcat-lite v0.09 beta since oclHashcat-lite v0.08 does not have a "Tahiti" kernel. This new beta include some unpublished code optimization for MD5 which is around 2%. Here is what I did: Quote:oclHashcat-lite64.exe -n 800 --gpu-loops 1024 -1 ?l?d?s?u --gpu-watchdog 0 --outfile-watch 0 --restore-timer 0 --runtime 28 --pw-min 8 -m 0 aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa ?1?1?1?1?1?1?1?1?1 This is a "Full-Power" command, its perfect for benchmarking. Here is the output: Quote:oclHashcat-lite v0.9 by atom starting... MD5: 8156.6M/s, on a single GPU. Now that is great! The funny thing is, even on extreme highly loaded workload (-n 800), which usually freezes the desktop, on this card the desktop was still useable. I do smell optimization potential on here. Before I continue with the other algorithms, lets compare what we see to the expected theoretical results. For this, I will use my stock clocked hd7970 vs. stock clocked hd5970 (1 GPU only!): hd5970: 1600sp * 725mhz (1160000) vs. 2048sp * 925mhz (1894400). This is a "theoretical" improvement of 63%. MD5: hd5970 = 4940M/s, hd7970 = 8156M/s. This is a "real-life" improvement of 65%. That means, the theoretical values perfectly fit the real-life values. Ok, another test. This time SHA1. Same command, just switching to -m 100: Quote:Speed.GPU.#1.: 2807.5M/s SHA1: hd5970 = 1690, hd7970 = 2807. This is a "real-life" improvement of 66%. Hits again the theoretical expectation. Awesome, I am starting to like this card. Here are some more numbers without comments of some algos I think many people are interessted in: Quote:vBulletin3: 2214M/s Now switching to oclHashcat-plus. I had to run this again on a beta version since the current 0.07 version did not work. First thing to test, of course, WPA/WPA2: Quote:Speed........: 127.9k c/s Real, 128.2k c/s GPU This is just a single GPU card, the hd7990 will surely make 220k c/s OK, the comparisation again: WPA/WPA2: hd5970 = 79k c/s, hd7970 = 128k c/s. This is a "real-life" improvement of 62%. Another thing that many people want to know is the multihash speed. Quote:1 hash (not reversed): 5182M Conclusion: This card rocks, I am looking forward for the 7990! Next steps: Wait for Linux drivers, then check out how to optimize GCN. RE: oclHashcat running on the new AMD hd7970 - arex1337 - 01-11-2012 Thank you very much! RE: oclHashcat running on the new AMD hd7970 - arnbju - 01-11-2012 Very nice! Is it possible to test the beta? Just got my card. RE: oclHashcat running on the new AMD hd7970 - goblin72 - 01-12-2012 Hi Can I crossfire Hd7970 with hd6990 ? RE: oclHashcat running on the new AMD hd7970 - forumhero - 01-12-2012 apparently people are overclocking the 7970 cards to 1400mhz on stock cooling too. atom, can you provide benchmark numbers for the 5970 with both GPU running? i believe a 5970 with only one GPU running is slower than a 5870 due to its lower clock speed. would be interested to see what you get when the 5970 is running both GPU RE: oclHashcat running on the new AMD hd7970 - atom - 01-12-2012 (01-12-2012, 09:04 AM)forumhero Wrote: apparently people are overclocking the 7970 cards to 1400mhz on stock cooling too. speeds are on oclHashcat-plus / oclHashcat-lite homepage RE: oclHashcat running on the new AMD hd7970 - atom - 01-12-2012 (01-12-2012, 08:45 AM)goblin72 Wrote: Hi you dont need crossfire RE: oclHashcat running on the new AMD hd7970 - atom - 01-12-2012 (01-11-2012, 11:41 PM)arnbju Wrote: Very nice!
