According to CNET News, Office 14 technical preview will be available in Q3, and release version in the first half of 2010; Office 2010 will come in both 32-bit and 64-bit versions.
If password encryption will be improved there — of course, we’ll update Office Password Recovery accordingly. Though it is already good enough in Office 2007 — even with GPU acceleration, the password recovery speed is only thousands passwords per second (see some benchmarks at Distributed Password Recovery page), so even relatively short passwords are secure enough.
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.
Here are the benchmarks for WPA recovery; we’ve run tests on one of the most powerful modern CPUs and a bunch of GPUs. Even GTX 280 outperformed Core 2 Quad Q6600:
ATI and NVIDIA arranged a new graphic cards fight, claims TweakTown:
NVIDIA has now moved the launch date for the GTX 275 up to April 2nd, the same day that ATI is launching the Radeon HD 4890. The two companies have both moved their launch dates up a few times on the two cards in an effort to gain a little bit of an edge over the other.
We’ll carry out our own examination and try Elcomsoft Wireless Security Auditor on both of them. Can’t wait to see which of the newdesigned cards will pass our acceleration test, yet it seems we should arm ourselves with patience until April 13th when GTX 275 will come onto the market.
