Enough with the HD 5850 and 5870 that appeals to 5%

You should be able to get those for under $100. (used at least).

I think I saw a 4870 new for $120 (may have been rebates involved).

That's cheap if you can get even a 4830 for $100. Maybe we will see a 5830 with even lower clocks, cheaper memory and less shaders for $200?

4830 for $100 is cheap? Yeah, but 4850's have been at or under $100 (theres almost always some model at newegg for $85-90 AR) for a couple months now...

I doubt we'll see a 5830, AMD has plans to fill the gaps more thoroughly from the start. The 4830 was more of a temporary part until it was essentially replaced by the 4770. The 5700s will fill the $150-200 void, while I assume the 5600s would supply our $100-150 options

So you're saying 5% is way too high of an estimate, given that WoW and The Sims are massively more popular and better-selling than cutting-edge FPS and aren't nearly as GPU-dependent as to require 5850/5870 level hardware?

OK, you've convinced me that the enthusiast GPU market is more like 2%. Thanks for your input.

If you can get a used 4850 for $100 that performs better than a 57xx costing almost twice as much, who cares about the 57xx series? So the 5700s will have dx11, but who cares when you can't run without disabling half the settings and forgoing aa/af? I remember Nvidia Geforce fx5200 costing $100, you could get a geforce4 ti4600 for the same price and it was way faster in dx8. The fx5200 supported dx9 but performance was a joke! You were much better off spending $200 for a radeon 9700 pro! Likewise if you have the money, buy a real 5850 or 5870 and if you can't afford that, get a 4850 or 4870.

Also there was a 4830 due to the huge performance leap from 3870 to 4870. The 4850 was 3870x2, while the higher end 5870 is now the 4870x2. Add in the fact that there's already a 4890 that has great performance, then there's little chance of something between the 5770 and 5850.

It's indeed an itneresting question how they will position all these great-performing but now cheap 4870s, 4870X2s - no DX11 but 5870's level of performance for how much...?

ATI is in the business of making $$. Once the lower derivatives of 5870 and 5850 are out on the market, 4870 and 4890 will all but disappear since ATI makes more $ on 40nm process than 55nm.

It is important to look at 5870 and 5850 as a starting basis on which low to mid-range performance will be based from here. Since those cards have 1400-1600 shaders, things are looking good for lower end derivatives. But I have a feeling 128-bit memory bandwidth is going to be a small limiting factor on these upcoming cards.

Also 5850 and 5870 are important since in 12 months, they'll be prices at $100 and $150, allowing us to upgrade for not more than $50-$75 after selling our old cards.

I am skeptical of something (HD5750) that has the same processing power as a 1 Ghz HD4890 when it only has 128 bit bus.

It will be interesting to see the tests when they come out.

Raw processing power is independent of the memory bus or bandwidth.

Yes but memory bandwidth matters for AA.

Sure but it's also useless without it, by itself.

In other words bandwidth is a seriously limiting factor - look at 4850 vs 4870...

But doesn't the memory bus take up space on the die?

So if a 128 bit bus is used (instead of 256 bit) more stream processors can be packed into what would be an identical sized GPU.

Or am I wrong about this?
