'Moore's Law has historically been driven by lower fabrication processes - and the transition to 28nm is set to power next-gen visuals on both PC and the new wave of consoles.' However, in the here and now, the GTX 680 is the new state-of-the-art. The GTX 680 is smaller, leaner, cooler (it really is very quiet indeed for a high-end GPU) and more efficient, and there's headroom left over in the technology for an even more monstrous processor - already rumours are circulating of a 2304 core, 3GB ultra high-end card, with the 384-bit bus restored and 3GB of GDDR5 RAM on tap. The gain in performance is also excellent - something we'll look at later on, but the basic facts speak for themselves. Also intriguing is that the memory bus is actually reduced from 384-bit in the GTX 580 down to 256-bit.

It features a mammoth 1536 CUDA cores, up from 512 (though the design is very different, so the cores are not directly comparable), while GDDR3 gets upgraded from 1.5GB to 2GB, with RAM speed now reaching 6GHz - a remarkable achievement. Die-size drops from 520mm squared down to 295mm squared, yet the transistor count rises from 3bn up to 3.5bn. The GTX 680 offers approximately twice the performance per watt consumed compared to its illustrious predecessor, the GTX 580. Moore's Law has historically been driven by lower fabrication processes - and the transition to 28nm is what will power next-gen visuals on both PC and console.

Prior to the release of this new technology, recent GPU upgrades for PC haven't exactly shown enormous levels of improvement (indeed the Radeon 6x00 series cards were in some ways slower than their predecessors) and one of the main reasons behind this was the fact that both AMD and NVIDIA were only able to fabricate their silicon at 40nm. It's a lofty claim but testing bears it out: NVIDIA's new 'Kepler' architecture is truly something special, setting the stage for the next era in graphical performance. NVIDIA claims that its new GTX 680 is the fastest and most power-efficient GPU ever made, offering significant performance improvements over its competition - and indeed its own range of current flagship products - while at the same time reducing the amount of juice it saps from the mains. We're using the peak power-draw numbers obtained by running real-world Batman: Arkham City.ДЈ the HEXUS Efficiency Score is a combination of bang4buck and bang4watt, we simply add the two to rate combined value for money and power efficiency.The era of the next-generation graphics core is finally upon us. The minimum allowable frame rate is 20fps but that scores zero.Дў the HEXUS.bang4watt score is a crude measurement of how much normalised performance the GPU provides when evaluated against system-wide power-draw that's shown in the table: the former is divided by the latter. Similarly, should a card benchmark lower, say at 40fps, we deduct half the difference from its average frame rate and the desired 60fps, giving it a HEXUS.bang4buck score of 30 marks. Should a card benchmark at over 60 frames per second in any one game, the extra fps count as half. 1 the normalisation refers to taking playable frame rate into account.
