HD5800 series and HD5700 series not yet at full performance

[Mungri]

However, we might see a benefical boost using dx11, which is why I got the card, not a 4800 serie one.

This is not a 'might', but a definate 'will'

I expect gain from more mature drivers, but minimal at most. I remember the days of the x1800 and the supposed "miracle" driver that never came.

Actually, IIRC, when the X1800XT first launched it had performance on par with the 256MB 7800GTX. 2-3 months later, it had a nice lead over the GTX, to the tune of 10-20%. It isn't really far-fetched to think we haven't seen the full potential of the 5000 series cards yet. One can hope anyway.

it isn't anything new that nvidia cards come up top in UE3 games

That's just an example where there probably will be a big performance boost once the drivers are sorted out. I remember something rather bad with the 4870 in WAW and Far Cry 2 as well. Those games also showed some good improvements after driver updates.

I'm thinking the "capacity" and "monster" wording of the source of information is leaning toward some type of major break through in the actual performance of the hardware which will benefit all rendering. I imagine they figured out an algorithm for maximizing power control for improved over clocking.

It's all speculation at this point in time. Nothing is certain about this.

deferred rendering + warps = fast

this would apply to cryengine3 and several other powerful 3d engines.

For Borderlands you would need to get into the config file to setup properly for a widescreen, the POV should be around 105-110 for 16x10, there is alos a bunch of other features left out even when you use max settings you can enable to get better eye candy. Just like UT3.

Interesting if true... ok guys correct me if i'm wrong but here's my hypothesis.

What if the 4800 series and now the 5800 weren't utilizing their shader cores (SP's) to their full potential since release? Lot people said Crysis wasn't optimised for ATI's but the 4870 has 160x5, what if it was only using 160x1 shaders since (not sure) most of the game were not meant to use more groups (types) of shaders or "TWIWMTBP" and other programmers used only 1 shader "type?" so the radeon might only used 20% of it's shader power? That's a difference from NVIDIA where their SPU's are not "multi-units" and were in a higher number (x1) @higher clocks. It could also have been all in the drivers tho. It could "explain" why the 5870 is "underperforming" (according to users who got that card as i do not have one myself).

The programmer doesn’t control how the tessellation unit itself calculates but works with 2 new types of shaders, the Hull Shader and the Domain Shader, which come before and after the tessellation unit in the pipeline. This makes DirectX 11 a tessellation superset of the Radeon HDs. Another way of putting it is to say that using it today alongside the Radeon HDs will allow developers to reuse and extend their work with DirectX 11, which means they might finally get interested.

Maybe Directx11 enabled games will use most of the shader groups inside the ATI GPU's now and the programmers can "offload" compute shaders tasks and others on to the other SP groups... ?

Maybe ATI has got a new driver that's being very efficient in DX11. The SPU's will be able to process physics calculation with the "compute shaders" and throw a big middle finger @Physx. Crossfire might now scale much higher with DX11.

Alot to think about. At this point it's all speculation. Need official confirmation of information in source.

they utilization depends on the game. more complex code will not pack enough instructions. usually they will use 3-4 of each vliw core. in bad cases it can be lower. its not like you are going to get more ilp out of games by a magic driver update. twimtbp has nothing to do with it. remember unified shaders? nvidia does not use vectors so each shader gets much higher utilization. both ATi and nvidia design their architectures around what programmers are doing. they take almost opposite approaches to their architectures. you will not see a huge increase just from a driver update.

I don't care if its twimtbp or not. I want performance.

Hehe no.. by the way that's why i said "..here's my hypothesis", constructive post in my book :P

I am no engineer in this, i expected to get clarifications as this seemed intriguing to me, i agree it's all speculation and we'll find out soon enough.

You will have but you have to wait Catalyst team to get the hands on the game...like the TWIMBP games

Since I'm sure that ATI has to buy a copy at release.

[AbelJemka]

Sure they have

LOL, good call
