AMD Radeon HD 6970 2GB

The Cayman XT GPU of the AMD Radeon HD 6900-series is a different design to that of the end units, which allow for twice as much work per clock to be sent to the stream processors than before. Although there are 64 fewer stream processors in the GPU than in the AMD’s previous –generation top-end card , the Radeon HD 5870 1HB each processor is capable of the high-precision maths that only a fifth of the HJD 5870 1GBs units could manage.

  AMD claims that the new lay out is 10 percent faster per square millimeter of GPU die than that of the HD 5870 1GB. Despite the naming of AMD’s HD 6900 series this GPU is successor to the HD 5870 1GB. The GPU has a frequency of 880MHz and 2GB of GDDR5 RAM operating at 1.375GHz (5.5GHz effective) over a 265-bi memory interface. This may sound paltry compared with the 384-bit interfaces of the GTX 570 1.3GB, and the GeForce GTX 580 1.5GB but the high memory frequency gives the HD 6970 2GB a respectable 176GB/sec of memory bandwidth.

  At 1920x1080 the HD 6970 2GB traded blows with the GTX 570 1.3GB which currently costs less. In Armall, we saw identical minimum frame rates from both cards, while Black Ops ran similarly fast on both cards, with minimum of 95fps from the Radeon and of 94 fps from the GeForce. The GTX 570 1.3GB raced

Intel Core i7-990X Extreme Edition

 The has been so much fuss about Intel’s new LGA 1155 processors recently that its easy to forget about Intel’s other range of LGA 1366 CPUs. Intel actually pitches its X58 chipset and corresponding CPUs as its high-end offerings; theoretically, this means they reside above Sandy Bridge-based processors in the performance tree.
As we’ve seen, though LGA 1155 CPUs and motherboards are incredibly quick and outrageously overclockable, and can put their LGA 1366 stablemates to shame.
Processors at the top of the range such as the Core i7-970 and Core i7-980xExtreme Edition sport sic Hyper-Threaded cores, allowing them to perform better than LGA 1155 CPUs in highly multi-threaded applications. It’s to this elite group of processors that Intel’s new release, the Core I7-990X Extreme edition belongs.
As the i7-990x

Teufel Concept D 500 THX

Most of PC speakers aim for maximum bang per buck: ear splitting top volume, booming bass a rock-bottom price seem to be the features that sell. Into the crowd of boy racers, Teufel’s latest 2.1 set glides into view like an Aston Martin, albeit with German plates.

  Teufel speakers are only available direct from Berlin, which helps to keep down costs. However at £449, this is the most expensive 2.1 PC speaker system we’ve seen to date

  It looks every bit as good as the price suggests elegant and understated, with a premium finish. There’s a solitary analogue stereo input and its deserves a signal from a high-fidelity sound card to do the speakers justice. And S/PDIF input would have offered a work around, but those who already own a decent sound card will be thankful not to have to shell out for another premium DAC chip. Unfortunately, there are no speakers cables include in the box.

  The wired remote has volume and sub woofer level controls, although the latter is calibrated too high by default. Useful settings were around 10per cent and the ratcheted design made fine adjustments imprecise. The remote also houses a headphone output and microphone input a socket on the subwoofer passes the microphone signal to the sound card. The integrates headphone amp sounded clear with plenty of headroom, but emitted a violent clunk while switching on and off.
