HEXUS.bang4buck and bang4watt

Putting all the numbers into perspective, let's take a closer look at overall performance and value for money.

In a rough-and-ready assessment of the cards' bang for buck, we've aggregated the frame-rates for all our gaming benchmarks, normalised them1 and taken account of today's pricing.

But there are more provisos than we'd care to shake a stick at. We could have chosen different games, the cards' prices could have been derived from other sources, and pricing tends to fluctuate daily, especially for new-release GPUs.

Consequently, the tables below highlight a metric that should only be used as a yardstick for evaluating comparative performance with price factored in.

1 the normalisation refers to taking playable frame rate into account. Should a card benchmark at over 60 frames per second in any one game, the extra fps count as half. 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. The minimum allowable frame rate is 20fps but that scores zero.

2 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. We're using the peak power-draw numbers obtained by running real-world Crysis 2.


It's important to remember that our bang4buck is based on a few titles and doesn't take other architectural advantages into account, but for 1080p gaming, the GTX 560 Ti 448 offers good value for money.

At the time of writing, a predicted £220 price tag puts the 1080p bang4buck result right in line with a standard GTX 560 Ti. If Gigabyte can shave a further few pounds off the price tag, the 448-core card would stand alone - a £210 asking price would raise the bang4buck score to 0.77, but there's a flip side to that coin; if Gigabyte launches at £240, the 1080p bang4buck score would dip down to 0.67.
