The problem with the 2600x2 was that it sucks. To put it bluntly. Now a x2 HD 3870 is something to write home about. Hoping it's not late that is like the x1950pro x2.

I believe they know this. I hope 7.11s fix the crap crysis demo crossfire performance, like acually having atleast 60-70% increase over single.

That's true, but somewhat misleading as well.

The RV670's VLIW arch will never be able to use it's theoretical maximums because it can't run dependent instructions in parallel.

For DX10 and OpenGL only- DX9 has a 3 frame buffer limit that prevents 4 way AFR. (so less efficient tactics like "SFR of AFR" have to be employed) In this situation, I'd think 3 way CF would be preferable.

Nonetheless, looks good, I like solutions like this.

Yer I know...
But whats the "average" utilisation of the stream processors in modern games anyway.... or better, what can be expected? 75% maybe?
R(V)6xx is running 64 vec5 threads right? So it would have to run at like 80% to match nVidias shaders performance....

What's "worth the money" is HIGHLY subjective.

If you have $40K a year to work with, quad fire and tri sli probably aren't worth it to you.

If you have a $150K a year, spending $900-$1500 on video cards may well be "worth it to you".

If you have less money, but value gaming highly and want to spend your disposable on computer parts instead of golf, it might be worth it to get double the speed for triple the price.

Only the buyer can decide what something is "worth" to them- there's no formula or rule.

R(V)6xx is running 64 vec5 threads right? So it would have to run at like 80% to match nVidias shaders performance....
I don't think there's any "average" utilization data available.

My point was just that "You may have the physical 1280 shaders, but there are factors that will limit their use."

Having 1280 shaders sounds a lot better than it will actually be, in terms of performance. When you consider having 320 shaders brought the 2900XT to the level of the 98 shader 8800GTS for the most part, a massive shader advantage doesn't seem to be the key factor here- parallel instructions, shader speed, and texture fillrate seem to be the key components of these card's performance equation.

My .02.

The more SPs the more wastage (in terms of shader power, percentage should remain the same if the whole ratio scales), but in terms of diesize vs performance, the R600 architecture still has a big advantage there.

Heck, R600 has 320 SPs + a fatty 512-bit bus, and it's still 10+% smaller than the G80! I'm not even including NVIO.

190mm^2 vs 320mm^2 is quite a big difference in chip size, even when G92 has 16 more SPs to unlock.
If nVidia manufactured G92 in 55nm, it would still have 271++ mm^2 as the die size as its best case scenario.

What I'd say is:
If R600 wasn't a fiasco financially, if AMD/ATI wasn't strapped for cash/market performance, 480SPs + better ratio on a hypothetical chip will become the new flagship in TOTAL performance.

It's 1.5X performance scaling, plus some more percentage if they have more TA/TF units and RBEs.

This hypothetical die would reside in the high 3XX/ low 4XX mm^2 area, and for a flagship, seems normal. You could clock it at ~700Mhz, it shouldn't too much- the current 3800s don't- and end up at 140-150W TDP.


But of course, they'd be swimming in MORE red if they went that way. The 8800GT would dominate sub $300, leaving this hypothetical chip little to compete in 400+ market, something that ATI can give up for now given its kinda shady stigma of the 2900XT.

Plus, it'd take more $$$ to engineer such thing.


2 RV670s on 1 board has the distinct advantages of a much smaller chip, flexibility in terms of yields, and still high margins for ATI.
