The Official RV630/RV610 Rumours & Speculation Thread

Two things.

One, I noticed that sweet post, Gee. It's a really neat guide for what to expect of RV630, and it lines up so well with G84 that we almost don't need actual benchmarks. :) But it's a really nice way to bound RV630 speculation.

I'm not knowledgeable enough to further extrapolate how RV630's lower intended resolution will skew the results (as alluded to in the new Eric Demers interview, the higher the res, the less the texturing units are needed, which suits RV630's lower res and proportionally greater texturing power), but it's an interesting extra data point. Then again, perhaps not, if one is supposed to think of res not in absolute terms, but relative to the GPU (where 8x6 would be very roughly the same for RV630 as 16x12 would be for R600). So, like leone said, res may also affect our guesstimates.

Two, upon rereading my previous post, I hope it's clear (especially given this post) that "hamster wheel" applies to me as much as anyone else, and so is intended as a convivial deprecation/metaphor/hamstropomorphication, not a patronizing comment.

Julidz, it's really down to the artists. One would think that, given the same artist, the game that's more shader-intensive (be it more short shaders or some long shaders) will look more polished and so better because the artist had more to work with, but it may not be that straightforward. Real time 3D is a compromise, and I wonder how apparent the differences would be b/w the compromises we're discussing. And, as Morgoth said, there may be a limit to how much you can substitute shadering for texturing.

But shader intensive doesn't have to mean longer shaders, just more shader calculation relative to texturing. For instance, I think it's fair to say that Humus' Doom 3 patch (substituted shader calculations for texture lookups) made D3 more shader-intensive. I'm guessing it's still not pushing as many shader calcs as FEAR, though.
 
Wait, what? 8x6?! :oops: Why even consider such an IGP-range resolution in the context of RV630?

He' s saying that at 8x6 RV630 should perform roughly like R600 at 16x12 (I think better, because it's more difficult to be pixel fill rate limited at that res, and shader and texturing power relative to R600 are higher than 1/4).

Anyway, about texturing, I read there are two big paths, one is with increasing the texture content and of course need of texturing power, the other going with procedural textures, which relies mostly on math.

Yeah, anaqer, I was too lazy to think of another 1:4 res pairing that matched up to the 1:4 RV630:R600 ROPs and bus width ratios. Though 10x7 and 20x15 springs to mind now (thanks a lot, brain), 20x15 is still out of the range of most monitors, which is probably why I didn't consider it.
 
Oh, so just a ratio thing... whew, I was getting worried RV630 would turn out that much weaker than previous estimates.
 
If you see the 8600 GT prices, they are not too different: In Italy you can buy one for 117€ VAT included (20%). But indeed, the price seems to suppose standard XT to be slower (with current drivers), as that chinese review seemed to point out. But seeing CoH behaviour in the it-review review for the 2600XT DDR4, it seems the latter card could be on par with the 8600 GTS in some instances. The only difference between the two is the memory bandwidth. Now, it is maybe possible that in R600 architecture bandwidth plays a more fondamental role than we can think?
R600 ha an "overkill" bandwidth, RV630 from the (few and non very reliable, I agree) first review data seems to be seriously limited by bandwidth...
This really puzzles me...
 
Radeon HD 2400 and 2600 series get priced
- €149 for the Jetway Radeon HD 2600XT 512 MB DDR3 PCI-e DVI
- €99 for the Jetway Radeon HD 2600XT 256 MB DDR3 PCI-e DVI TVout
- €89 for the Jetway Radeon HD 2600PRO 512 MB DDR2 PCI-e DVI TVout
- €69 for the Jetway Radeon HD 2600PRO 256 MB DDR2 PCI-e DVI TVout
- €59,95 for the Jetway Radeon HD 2400XT 256 MB DDR3 PCI-e DVI TVout
- €54,95 for the Jetway Radeon HD 2400PRO 512 MB DDR2 PCI-e DVI TVout
- €44,95 for the Jetway Radeon HD 2400PRO 256 MB DDR2 PCI-e DVI TVout

The interesting thing is that AMD doesn't have any card for the $199/€199 mark so, unfortunately it has to live with a big gap between the 512 MB Radeon HD 2600XT and its current flagship, the $399/€350 Radeon HD 2900XT.

This is not interesting thing, this is a very bad thing from user aspect.
 
3dmark2k6 score looks very bad (if they used default setting) with quadcore CPU, r600 shine in 3dmark2k6 when same goes for the hd2600xt gddr4 too than game performance will be umggg....... :cry:

Why is it bad? Target performance was that of a X1950GT. And isn't that exactly what it does, but for a cheaper price, lower powerconsumption and DX10 support? nVidia fears the HD2600XT the most so I've been told.

How is the HD2600 XT GDDR4 any cheaper than a X1950 GT ?
Also, a single 3DMark score from a "preview" doesn't give us any confidence to talk about it being any faster and/or cheaper (considering the recent price-cuts from Nvidia) than a 8600 GTS.

Because mainstream users not want buy mainstream cards in this generation what performance is the same as the last generation mainstream card.

Why they think users not want a single more frame,but happy when can buy the same performance 15$ cheaper than the last generation mainstream card, consume 10watt less, and can do dx10 (who cares now)?
 
IMO, based on the R600s performance i think its too early to judge whether or not the low/mid range variants will perform by looking at 3dmark scores. It seems that the R6x0 do very well in 3dmark but real world performance might be a whole different story.
 
Maybe some hope... ;)
2600Pro(600/700MHz) with A64 3000+ :

700MHz GDDR3 and driver says 2600XT, and now look on the "2600XT" 3DMark scores of PConline:
2600XT GDDR3 Preview @ PConline

Google-translation

So I think the real 2600XT will be on 8600GT level and maybe in some games higher and that for 100€ -> not bad!

The XT gdd3 not looks like as in 8600gt level.
What you linked now the hd2600pro with gddr3 memory score 7740, in the other link the hd2600xt score 8327 the 8600gt 9981. (don't forget 3dmark2k5 default setting is 1024x768 not 1280x1024).
Hd2900xt gtx level in 3dmarks, and in games....
When the xt so slow than for 100euro not really have any good price/performance rate, because ~20% slower and ~10% cheaper than the 8600gt.

BTW. Xpertvistion/Palit hd2600xt gddr3 cost 98.65 euro, the 8600gt 101.41euro ouch for AMD.

Looks like this will be another mainstream ***** from ATi/AMD, x700-x1600-hd2600, but now the things looks worst than ever for ATi/AMD because NV maked **** mainstream cards too, and AMD not have a fighting chance.
For me looks like the whole company (not only the GPU part) lost they faith about everything, and they can't do anything in the right way, i hope someone do something with this company before they are total out of control.
 
I find it baffling that ATI still can't find their groove in the mainstream segment. And it's even worse considering the process advantage.
 
Yeah the mainstream cards on both sides have really disappointed me this time around.... On one hand you have only 32 unified scalar shaders and on the other you have a card with 4 rops... yipee.
