It looks like AMD has outrun NVIDIA today. Its World’s First Microsoft DirectX® 11 Graphics Processor, presented a few hours ago in Taipei, is currently the best hardware for Windows 7. Catch up, NVIDIA! However not many details of it suggested. At least enjoy the graphics:

We wrote about Cost-effective video cards recently, but what about better ones, if the prise does not really matter? Just read Best Of The Best: High-End Graphics Card Roundup at Tom’s Hardware. Large. Expensive. Power-consuming. But really fast — so best choice if you deal with GPU acceleration.
Btw, don’t forget to get a good coller for your new card — like this one.
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?
