Nvidia's Titan graphics card is a beast of a GPU, not only because of its power, but also thanks to its £800 RRP. And despite only being revealed at the start of the year, it looks as though it's already…
Nvidia's Fermi GPU wagon continues to spout out top-notch cards at low prices, and perhaps none are more appealingly spec'ed and priced than the GTX 560 Ti. It tears into the sub £200 market by some margin if you shop around, but can it compete with the stellar cards AMD are touting at similar price points? Read on to find out.
AMD has just dropped us word of their latest graphics card release, the ATI Radeon HD 4890, which they’re claiming is the most powerful graphics processor in the world.
The beast runs at 850MHz, has 1.36 TeraFLOPs of processing power, as well as 1GB of GDDR5 memory and the functionality to cram four of these things in the same machine, using ATI’s Crossfire technology.
It’s notably faster than its predecessor, the HD4870, but slower than the dual core X2 variant. Pricing reflects that, with the card retailing between £185 and £200. It’s not a massive leap, just an evolution of existing cards, but it’s certainly a solid upgrade if you’re running a graphics card that’s a couple of years old.
There’s a lot of software out there for cracking wireless passwords, and most of it’s legal. Why? Because it’s sold as a way for network administrators to ‘test’ their network’s security. Of course, there’s nothing to stop you ‘testing’ a network that you don’t own, in a coffee shop or airport, for example.
Most cracking programs use your PC’s CPU to do the hardcore number-crunching, but it turns out that the graphics card is actually far better at doing the kinds of calculations necessary. How good? Well, an above average quad-core CPU, the Intel Q6600 can only accomplish 1,100 passwords per second, whereas a similarly above-average ATI HD4870 graphics card can smash through 15,750 passwords per seconds.
Who woulda thunk it? Luckily, we might be seeing some of this power hit regular programs too, with Nvidia’s CUDA, ATI’s Stream, and Apple’s OpenCL frameworks. The graphics card isn’t best at every type of calculation, but if a program can intelligently route calculations to their fastest solver, then we could see blazing program speed increases in the near future.
The mid-range of graphics cards sells well. To consumers it represents that sweet spot between getting awful gaming performance and paying through the nose for a bit of silicon. NVidia’s Geforce cards have done rather well out of that market in recent years, but ATI aren’t letting them get away with it – they’ve given us the HD 4830…
