NVIDIA GeForce GTX 690

     Blending the power of two Kepler GPUs, the GeForce GTX 690 GPUs and a whopping 4GB of GDDR5 RAM is the fastest graphics card ever built by NVIDIA. It’s built from a combination of aluminium and magnesium alloys, and features a dual vapour chamber cooling system for quiet-yet-efficient airflow.
    With 3,072 CUDA cores powering this beast, the GTX 690 delivers roughly the same performance as two GTX 680s. NVIDIA's Kepler GPU architecture has been designed from the ground up not just for maximum performance in the latest DirectX 11 games, but optimal performance per watt. The new SMX streaming multiprocessor is twice as efficient as the prior generation and the new geometry engine draws triangles twice as fast. The result is world class performance and the highest image quality in an elegant and power efficient graphics card.
   Nvidia’s Turbo Boost technology remains intact, though, so that core clock will adjust up or down depending on how much work the GPUs are doing. Adjustments are made every millisecond, and the GTX 690's 915MHz core will hit a peak of 967MHz when it's at maximum load.
 
      Aside from the clock drop, little of the GTX 680 has been changed. Each core is still accompanied by 2GB of 6,008MHz GDDR5 RAM, for a total of 4GB across the board. There have been no architectural changes, either, with the eight huge clusters serving each core still packing 192 stream processors each. Across the entire GTX 690, that means there are a mighty 3,072 stream processors and just over seven billion transistors.
NVIDIA Quad SLI® Technology3
   Used by the most demanding gamers worldwide, Quad SLI lets you link up to two GeForce GTX 690s together for astounding performance. And with NVIDIA’s track record for fast and frequent software updates, you’ll not only get the best performance in existing games, but future games too.

AMD Radeon™ HD 7990 Graphics

AMD has finally released its new HD 7990, it uses two HD 7970 GPUs mounted on a single board. The current generation AMD GPU series collectively known as "Southern Islands" were released over a year ago, with the beginning of its rollout in January 2012.

         The Radeon HD 7790 released last month it’s a product most gamers have the potential to enjoy considering its $150 price tag. The HD 7790 took the chip count for the series to 10 distinct 28nm GPUs. Still AMD feels they need to offer an ultra-expensive graphics card as well and therefore today they are releasing the Radeon HD 7990. Although it's been over a year since they launched the Radeon HD 7970, we are just getting an official dual-GPU version, in truth they have been around for some time.
   In the case of the Radeon HD 7990 it takes a pair of 7970 GPUs with overclocked cores (from 925MHz to 1000MHz), while boosting the GDDR5 memory from 1375MHz to 1500MHz. These clock speeds happen to match the 7970 GHz Edition, though the 7990 doesn’t feature a Boost clock, so we feel the GPUs are better compared to the standard 7970.
Radeon HD 7990 in Detail
      Here are some figures that AMD is throwing around to describe the Radeon HD 7990: 8.6 billion transistors, 4096 stream processors, 8.2 TFLOPS computer power, 6GB GDDR5 and 576GB/s memory bandwidth. The Radeon HD 7990 is a monstrous graphics card measuring 30cm long (12 in), making it 3cm longer than the 7970 GHz Edition.

        Cooling the "Malta" GPU are two massive aluminium vapour chamber heat sinks, each with 62 fins and four heat pipes. The vapour chamber design was first implemented by the Radeon HD 5970 and has since been adopted by numerous high-end AMD and Nvidia graphics cards. Heat is dispersed by a trio of 75x20mm axial fans that pull air in from inside the case and push it out the back. The HD 7990’s fan operates quietly for the most part, but despite the card's impressive idle consumption of just 15 watts, it still chugs up to 375 watts under load, so the fan does kick up a little during heavy gaming sessions.
