NotesWe're running the Radeon HD 4850 512MiB under both our mid-range platform, detailed above, and with our high-end setup, shown on page seven.
The reason for running two platforms and comparing it against different cards lies squarely with the price.
At a guesstimated £125, the pricing is decidedly mid-range, so why should we look at against, say, a GeForce GTX 280, costing nearly four times as much? Knowing this, comparing mid-range performance, with mid-range settings, against the likes of stock-clocked GeForce 8800 GTS 512, 8800 GT, and 9600 GT makes sense, as well as adding ATI's own previous-generation HD 3870 and 3850 cards.
But the intrinsic nature of the Radeon HD 4850, which we'll go into serious detail on Wednesday, means that it punches well above its financial weight, so much so that NVIDIA's been obliged to reduce the pricing of its GeForce 9800 GTX from around $290 to $199 (£179 to £125). We'll see this price-drop rolled into etailers' catalogues at the end of next week. This is precisely why we've added the BFG card, currently etailing for around £179, to this mid-range line-up.
Our mid-range settings run the benchmarks at 1,280x1,024 (720 for Lost Planet) and 1,680x1,050, with mid-level image-quality enhancements on everything bar Company of Heroes. Our high-end platform, more for comparison's sake than financial parity, extends the resolutions to 1,920x1,200 and 2,560x1,600, with high-level I.Q to boot. A £125 card shouldn't do too well there, but HD 4850 shows promise. Remember, you can't cross-compare, say, Enemy Territory 1,680x1,050 4xAA 16xAF performance between the two setups; one runs mid-level quality and the other high-level quality settings.
Got all that?
