AMD: R8xx Speculation

Hell, I say it is completely angle independent!

Of course, the real world implications will be variable. Since R520 (and G80 for that matter) the IQ difference lines are diminishing, regarding AF.

 

Can anyone explain to me what is this And why is this such a big deal

All I know about AF is that it used when you view your textures are at a very oblique angle.

 

Have you ever suffered from plain obvious angle-depended and undersampled AF quality? Don't tell me you missed the whole R300~G71 time line.

 

These days they're more determined by how much the drivers are 'optimizing' the texturefiltering, rather than what the hardware is actually capable of

 

Hehe!

 

Is there anything about hdmi TrueHD/DTS-HD MA bitstreaming?

 

I dont play games.

I missed every thing prior to G80.

I just wanna know what is the deal with AF, this pic/holy grail, and angle independence.
Any resources/tips/pointers welcome.

 

Yep, looks to be on par with S3, which was the only one with completely angle independent AF before

 

Well, to be honest, NV got (near) perfect AF implementation since G80 introduction, but R800 just hammered the last nail now. Both implementations are good enough for for the time being, though, nothing revolutionary, but it's good to finally close this chapter, regarding AF quality after so many years.

p.s.: NV will probably follow suite with GT300, just not to fall behind regarding this "check-box" feature, for the PR sake.

 

Does D3D11 mandate this quality of filtering?

Meh, the new AF while technically a nice achievement won't mean anything for me in games. Couldn't tell the difference between R600 and G80 and I certainly won't be able to tell the difference between G80 and Rv870.

As far as I know, D3D11 doesn't have any more strict requirements than D3D10 did.

 

Not without 400% zoom-in, of course.

 

Isn't it a question of the right driver? I'm not sure, but you can get bitstreaming today if you rip your movie and play it with MPC HC (not sure, how ArcSoft TMT can handle this).

 

There is no information about quality concerning flickering, which was the problem of filtering on Radeons since R600 even AI was turned off.

 

That should be evaluated additionally within the game titles. Let's hope the AI set won't be so aggressive this time.

 

The angle dependency is much less of an issue ((And has been since the X1900XT/G80)) than the inclusion of mipmap and LoD filters. That need to just go away. I' wouldnt shed a tear to see the "Trilinear Optimisation" mode go away. And just force HQ all the time. The performance you get from using is not even worth having it the control panel these days.

 

I "upgraded" from the bamboo cane chair I was using to a wooden, uncushioned, dining chair. The only seating related hair round here is hair shirt. Nice headphones, a nice 22" CRT monitor, my clacky IBM keyboard and classic Explorer 3 mouse are ample compensation though

I don't know, to be honest. Could be overheads, which normally are covered by the contribution margin you realise when you sell your stock.

 

Clearly I'm out of touch. Bit embarrassing really. I was actually planning on buying the 2GB HD5870 (even though I hate the cooler, damn it's yucky and despite the fact the performance is worryingly low), but that's because I always buy "excess" memory.

The thing that gets me about the performance of HD5870 is that it appears AMD is basically saying "that's it, we're bandwidth limited and GDDR5 won't go much, if any, faster".

This is a dangerous point because I strongly believe Larrabee is considerably more bandwidth efficient. So, either R900 is a total rethink in the Larrabee direction or AMD's fucked in 18 months. I don't care how big Larrabee is (whatever version it'll be on), I want twice HD5870 performance by the end of 2010. The dumb forward-rendering GPUs are on their last gasp if memory bandwidth is going nowhere.

Of course if AMD can make a non-AFR multi-chip card that doesn't use 2x the memory for 1x the effective memory, then I'm willing to be a bit more patient and optimistic.
