yeah but isnt the price aswell, i payed about £130 for my 4850 2 yrs ago the 5850 is around £230 £100 more.
I've tried talking myself into buying a 5850 or 5870 but I just can't, they are too expensive. For the cost over the card I have now, I don't think a 5850 is that impressive really. It's no more an important card than the 8800GT was when that was released for about £130. People seem quick to forget how cheap last gen cards were last year, even the 4890 was £125 a few weeks after release.
OK, lets be honest and not rewrite the history books.
A 4850, overclocked NEVER CAME CLOSE to a 4870 in performance, it didn't overclock very well and had a massively stunted bandwidth due to memory. A 4870, the top end card that wasn't even closely matched by its lower end 4850 brother, was £180 or so on launch.
This gen a 5850 which most certainly does match its big brother(5% difference both maxed out), which only has low stock clocks but isn't massively crippled like the 4850, was £200 on launch, I actually got mine for £193, about a week after launch.
The price is still £200 rrp, you can still find them for VERY close to this, you've been able to find them VERY close to this since launch. RETAILERS are marking them up, RETAILERS are making a killing on them because the consumer is willing(stupidly) to pay it.
SO last gen to get the best AMD card around cost £180, this time £200. What a massive difference.
The reason for the price difference is fairly simple, first GDDR5 costs several times what gddr3 does, that was half the reason for the low cost of the 4850. Also was a very mature 55nm process that had a cheap cost per wafer and massive yields for AMD.
40nm is a horrible process, wafers cost the best part of 50% more and on top of that yields are way down. Core costs are OVER 100% higher than last gen.
The fact that to get a similar level of performance, in terms of getting a top end card, has gone from £180-200, is brilliant. Because of the core cost increase to AMD, we could have seen the £300 5870 as 20-25% faster than a 5850, but a 5850 crippled so it could never get close, then you'd have a point.
As for looking at one game to determine performance, thats ridiculous, you could have gone with Metro 2033, probably the best looking game around right now, the 5870 is twice as fast as the 4890 in that, its showed the absolute best scaling in performance so far of any game.
Meaning, double the performance is certainly there. Not all games show it, hardly surprising and nothing new.
My 1Gb 4850 cost me £73.99 (brand new) form OC....in July 2009.
The 5850 which is roughly x2 as powerful costs more than x3 as much.......
Anyone who thinks a 5850 is worth more than £150 at this stage in its lifecycle is a moron with more money than brains.
Hardly a fair comparison. You are looking at a card sometime through it's lide cycle and as such the price has dropped.
You'll see 5850's for £100 in a years time.
Still doesn't change the fact that the 5xxx series cards, cost to power ratio, is still way too high..for a card nearly a year into its life cycle.

Lets not forget what happened last time there was no competition; when the Nvidia 8800 series was ruling the roost and ATi had nothing. The 8800GTX was £350+ and the 'value offering' high end card, the 8800GTS 320mb, was around £220. Nvidia's replacement for the 7900 series, the 8600 series, were bare minimum offerings that were barely faster (and in some cases slower) than the old high-end kit.
We can see the same pattern with ATi's 5xxx series today.
The only thing I'm disappointed with is the £500 I had to pay to crossfire 5850s 6 monthes after launch.
