Water cooling, liquid nitrogen, and dry ice – which gets the most of your ATI Radeon HD 4890 graphics card? Learn it from Zac O’Vadka today’s post.
The only our product that works with ATI cards (right now) is Wireless Security Auditor, but interesting news anyway: ATI Radeon HD 4770 Info Leaked. I’ll second the editor’s opinion that it will make a good competition to NVIDIA’a 9800GT (of course, supported by EWSA, too).
Even more news from AMD/ATI: AMD Athlon X2 7850 & Phenom II X4 955 are coming. Though according to our tests (e.g. with Advanced Office Password Breaker that supoorts up to 32 processors/cores; btw, it has been updated today), multi-core AMD chips are still slower than Intel ones.
You should be aware that Distributed Password Recovery and Wireless Security Auditor work not only with NVIDIA GeForce cards and Tesla supercomputers (in terms of GPU acceleration), but with professional Quadro cards, too. We never compared the performance of GeForce and Quadro, though. Curious? Then read the Nvidia Quadro FX 4800: Workstation Graphics At Its Finest? article published at Tom’s Hardware today.
Technically, Quadro FX 4800 is very similar to GeForce GTX 280. But have a look at the Performance Comparison. On some tests, Quadro is up to 10 times faster than GeForce. Yes, almost the same GPU. Yes, same version of drivers. Amazing. Just note that the retail price on FX 4800 is in $1600-$2000 range. But if it can do password cracking at much higher rate than GeForce (again, we never tried it, sorry), it looks like a good investment.
An article Best Graphics Cards For The Money: April ’09 : March Review/April Updates also worth reading.
In case if you missed it: new ATI Catalyst drivers (9.4) now available (you can read the release notes for details). For some reason, some driver files have been renamed (well, not in 9.4, but in 9.3 released a bit earlier, though that version was really buggy and we cannot recommend to use it anyway), and our WPA password recovery (audit) software was not able to recognize Radeon cards anymore.
Well, to make the long story short: simply download the latest ATI Catalyst drivers and updated Elcomsoft Wireless Security Auditor :). Just note that this (new) version of EWSA will not work with drivers version 9.1 or older.
In the meantime, NVIDIA CUDA 2.2 (beta) released. Does that actually matter? Yes, because NVIDIA Tesla C1060 and S1070 are now officially supported on Windows. Besides, we need to have a look at Zero-copy support for direct access to system memory, because it may speed-up the GPU-enabled password cracking on some particular algorithms.
The German c’t magazine (issue 06/09) has published an article about cracking of NTLM-hashes with graphic cards. In this article pen test experts from SySS GmbH bring up a touchy question of how fast an intruder can break into your system. How long should your Windows logon password be, so that you could keep having your beauty sleep?
Elcomsoft Distributed Password Recovery was run on dual-core AMD Athlon X2 4850e, 2.5 GHz, with Nvidia GeForce 9800 GTX installed. The cost of the test system is worth the effort. One can fetch it for only $1K.
Now, what is the outcome?
