To be honest, I'm kinda surprised. Unless they are gonna release it as very cheap single gpu boards, or multi-gpu high end boards, I am surprised they have quoted as being at least 50% faster. The 8800GTX/Ultra is already performing above the 3870 by that amount (at least), so really ATI needed to come out with products that are at least 100% faster.

Only rationalisation is that they are aiming for cheap manufacturing and costs this time round, rather than all out face ripping performance. (basically gunning for the low to mainstream market now as they took a significant blow with the 2900xt stuff).

Above not worded very well lol.

The r700 is meant to be multiple chip so obviously individually the chips aren't going to be as powerful.

The RV series of chips have in the past been the codenames for budget and mainstream parts. I'd therefore expect a 50% gain on the previous high end part (r600) to be quite impressive. RV630 or 670 (cant remember which) is the HD38xx series of parts. Although these outperform the R600 based 2900 series, they are priced in the mainstream and budget sector.

R700 will be the performance orientated part. I have no idea how that's shaping up though

ATI/AMD have already stated that there will be no high end GPU from them this year. There was a thread on it somewhere. That's why Nvidia has bumped back the new high end 9800.

It was bs last i read.

R700 is meant to be on track for ths year sometime utilising multiple chips instead of just one all powerful chip as it has been in the past.

Yup it was people misreading their plans.

R700 is still on for this year and is a quad mini-gpu chip.

 

[Scougar]

So is that bad news as the 'product' RV770 is only just over 50% faster as such, and not one chip is 50% faster

Matthew

 

[psychas]

i think its to early to tell yet, i would look to 9800gx2 and 3870xt2 before r700 series as r700 is still just a guessing

 

[HeX]

These RV770's will be up against the 9600GT parts that have recently been benched.

thats not strictly true, the 3870 isn't faster than the HD2900, its faster in some cases and the 2900 is faster in others, crysis for example is faster on the 2900, proberbly due to higher memory bandwidth and such, im shocked what happened to the HD2900 series, on paper is a monster, 512-bit ringbus memory interface (256-bit bi-directional i believe) 320 stream processors and a decent clock rate, shame didn't work out better really or we would be getting 9800GTX now/very very soon, doesn't lack of competition suck

r700 seems to be based around more chips = better performance scaling judging from the rumours around at the minute.

indeed, its the way forward to be honest, parallelism has always been possible with graphics cards, but having multiple cores on one die eliminates the potential slowdown caused by SLI bridges and such, imagine this for example:

quadcore GPU with 128 stream processors/core clocked at something like 2Ghz and 24 ROPs clocked at 1Ghz, imagine the shading power

 

[Gerard]

Mad thing is 3dfx were doing that in 2000 Well not on one die but the principal remains the same.

yeah its all changing in the PC world now, its not raw Mhz that wins nowadays, its all about parallelism and efficiency, and just as important pricing, i think the current generation R670, G92 will be the last single core graphics cards, as well there proberbly all gonna have embedded DRAM like the 'xenos' processor for AA without performance hit

 

[Scougar]

Doing the split (parallel), itself would be done on the card for it to be effective long term. The current way it's being done (or at least the way I understand it) is that the driver (i.e. CPU) is doing all the work deciding which card gets which data. It needs to change so that the CPU just gives one set of data (i.e. less overhead for the CPU) and card splits the work accordingly.

The only disadvantage of this is that it would mean possible conflicts with certain programs, thus I assume would mean a programmable part (or just get smarter with the way the data is split up).

[Streeteh]

To be honest this seems like a logical step for AMD/ATI. There has and always will be more money in the budget market, a very small proportion of PC users are willing to pay for the be-all-end-all components, especially considering that the top end cards tend to have a rather poor price to performance ratio.

Take a look at the ultra, it is nearly 3 times more expensive than the 3870 but offers performance that isn't even double that which the latter offers.

 

[Scougar]

I doubt they will have embedded dram, unless it's a lower end consumer part. Obviously this has no basis, just my opinion.

The companies STILL need to sort out the issue with sharing memory. i.e. it's gonna be pretty expensive and stupid solution to have a quad gpu board, and then have 4 banks of 512MB on board to suffice crossfire. It would be a LOT better and cheaper to run just 1x 512mb (or whatever) if they managed to sort out this problem.

The only disadvantage of this is that it would mean possible conflicts with certain programs, thus I assume would mean a programmable part (or just get smarter with the way the data is split up).

The other disadvantage will be water cooling with multiple cores all needing attention only the full face waterblock solution will be viable.

So every time you change your graphics card, you'll need a new waterblock.

[Scougar]

Not really. If you have an extended block to cover two vertical chips, then a 2nd block to cover the other 2 vertical chips. As long as the 2 and 4 way configs were the same layout then you'd not have an issue.

This way you have a 2 gpu block, that can accomdate all gpu style (possibly even a 1 gpu pcb). The water connectors would still be at the top of the card, you only need 2 instead of 1. It's not really important to a major manufacturer though.

Yeah R700 is scheduled for this year still, it was their chipset based on R700 (for motherboards) that they were on about for 09, the gfx cards are still coming, supposedly middle of the year, as Nvidia's gona release their proper next gen (G100/GT200) around the same time, thats why the 9 series are just more over year old 8 series again.
