REVIEW: PNY GeForce GTX 680 Enthusiast Edition graphics card

PNY roll out their reference build of Nvidia's GeForce GTX 680 card. Packing in the latest "Kepler" architecture and offering superlative SLI options, it's a beast of a card. Does it hit the price/performance sweet spot though? Read on to find out.

NVIDIA unveil flagship GTX 690 dual-Kepler graphics card

Nvidia have revealed their new flagship graphics card, the GTX 690. Available from May 3rd for $999 (£615), it features a dual-Kepler GPU with cast aluminium casing that should squeeze out performance equal to that of two GTX 680s pulled…

REVIEW: Nvidia GeForce GTX 560 Ti

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.

Nvidia launch "bang-for-your-buck" GeForce GTX 460 GPU

Nvidia are today launching the GeForce GTX 460 GPU. Costing just $199 (£135) for the 768MB version or $229 (£150) for the 1GB card, it boasts mid-range specs at low-end pricing, which should make it a very enticing offer…

ATI unleashes the Radeon HD 4890

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.

Graphics cards are much better than CPUs at cracking Wi-Fi passwords

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.
