Fermi launch prediction

It really has more like 48% more transistors. And even then if you go by the ever-more heurstic 'Gelsinger's law', 100% more transistors is 40% faster, 20% faster is about right really.

That would sound ok apart from the rumours that they have had to downclock it get it to work.

Y'know we should have a thread where we keep track of predictions forum goers make just for a laugh. We could call it the hardware bookies or something.

Anyway, my predictions are as follows:

The GTX 480 and 470 are released at approximately £500 and £370 respectively including VAT. Review sites show the GTX 480 to be approximately 20% faster than the 5870 excluding some benchmarks where Nvidia always do well in, where the 470 overall will look to be about equal to the 5870 - the big difference being that the new Fermi cards utterly crush the older GTX 200 series in games that use PhysX where the GTX 480 is around twice as fast (or more) as the GTX 285. Some will be outraged by the price, whilst some will justify the price (after having bought 3 of the things) citing exclusive features and how they're priced relative to the GTX 200 series cards. The ratio swings heavily in favour of the former camp, however, and Nvidia drops the price by about £100 on the 480 and £50 on the 470 about a month after launch.


I think Nvidia would love those performance numbers, and those numbers are probably what most of us expected some time ago, think I read somewhere supposedly from an Nvidia source that 470 will be 20-25% faster than GTX285, given 5870 is 50% faster that doesnt bode well.

Hope they will be round about £300 in may,As i can get one instead of a ati 5870:D
Saying then i will have to buy another PSU as my HX 520 might not be powerful enough for a 480 GTX,But i hope the lower models will be ok,Which i doubt lol

Indeed.


Since when is there ever super-linear scaling - only in ATI fanboys pipe dreams.

You probably would have to get a 5870 at the very least to see reasonable boost in performance.

Depends if you are prepared to overclock the 5850 and what res you play.

I had a gtx260 216 witch was watercooled and overclocked to 730/1612 + so matched or bettered a gtx285 at stock.

With my 5850 which is overclocked and is faster than a stock 5870 I saw a very good performance boost in every game.

If running the 5850 at stock though and especially if your gtx280 is overclocked, then the gain won't be so noticable.

>I cant see a 5850 on here for less than £251.99. Am I missing something?


Looking at another online retailer I found

5850 stock - £194.52
5850 Vapor-X - £218.54
5850 Toxic - £230.55

but they are all out of stock.
