Looks like "Qimonda" is skipping GDDR4 and going straight to GDDR5!!!

Volume production expected in first half of 2008!!!

So, are we going to wait some more??

Wait for what? Does it make an actual difference to the end user what TYPE of memory is used?

not something i'd bother. as long as i get 20 - 30 fps, i'm good.

would PCIE 1.1 limited bandwidth causes bottleneck in utilizing gDDR5?

No idea, but there has been a rumour long ago that PCI-e2 is coming soon

Its good, for 128-bit memory bus width mid range cards, for high end card like HD 2900XT, I don't think it needs a faster memory. Probably on future faster cards might need it but still too early, far too few cards utilising even GDDR-4

if the cost par with DDR4 why dun use GDDR5 ? buyer also will few nicer "P

LOL..

feel good factor for end users...

eg.. mine is GDDR5, yours are GDDR4

mine pwned urs


LOL

Eh? This question is like asking whether there's any difference in using DDR and DDR2.....

Ya ya..... if one card offers GDDR4 and the other offers GDDR5, I'd probably go for GDDR5!!! Of course, have to look at the cost also....

Is there really? Does the end user even know what difference it makes besides the 5 is bigger than 4? Is 5 a guarantee of better performance than 4? Memory bandwidth is a function of bus width which is independent of the model number and frequency which is to some extent helped by new models. Also the newer types tend to have a higher latency at the same clocks, so they have to be clocked much higher before you can see most of the performance benefit. Remember the gddr2 radeon 9800pro which performed worse than the gddr1 version?

GDDR4 isn't even that widely used yet. Top end cards are still using gddr3. So this GDDR5 thing is still a way off. I wouldn't hold my breath waiting for it.

I have a noob theory.

The greedy manufacturers have already developed GDDR 10 since year 2000, and they are holding it back, releasing one version at a time.

and somehow this = profit!!!

win??

wait, that means intel already have tacheon flux processors and AMD's orbital mars space station is already developing a time distortion processors, along with ATI's 100% realer than life photorealistic GPU codenamed "Real graphic x696969xtx".

OMG!!! Them greedy bastart!!!

I think i'll just stick with my GDDR3, coz I'm a stupid lamb.

That theory doesnt work, unless there was no competition in the industry.

Your arguments are somewhat flawed.

Firstly, you can't talk about whether an end user can see or feel any difference between GDDR4 or GDDR5 besides the number. For the average end user, maybe so, but it is like saying that since they are only average user, why not use DDR and not DDR2/DDR3 as they won't feel the difference anyway. If you say that DDR2 is getting cheaper compared to DDR, then the same can be said for GDDR5 compared to GDDR4!

Secondly, the difference to an overclocker is important, eventhough it may be just a minor increase. Let's say that GDDR5 is only 10 fps faster than GDDR4 in real-world games, it is still better for an overclocker!! Again, if you compare the speed that DDR2 gives you as compared to DDR1, is there really any huge gains?

Thirdly, your arguments are only speculations. You do not know how GDDR5 will perform as compared to GDDR4. I mean, what if GDDR5 is 50% faster than GDDR4? What then?

Lastly, I'm not into debating about DDR2 vs DDR, just taking it as an example/analogy. Technology is advancing and we welcome them with open arms as the end results are still for the benefit of us end users anyway!!!

Hah! I do know it will not be 50% faster than GDDR4 at its introduction. As it is right now GDDR4 is still ramping up. And as i said, it really doesnt matter what gddr version number it is (or bus width even, the zomg why still 128bit complaints about the midrange cards are quite pointless). The most important factor is memory bandwidth (and how it can be utilized, R600 has massive bandwidth which it can't even seem to use), and most people seem to overlook this.

True. However, I'm wondering whether "Qimonda" skipped GDDR4 because the performance gains is not as much compared to GDDR3. I guess we just have to wait and see how it performs.....

lolx. it's good for the business well being la dude. all enthusiast short mind will ne trapped and they will spend like shit. meh. technology is strongly manipulated by economic imperialist nowadays. even gddr88 wont impress me.

new technology doesnt really work really well than old tech sometimes

Well, business is business. Nobody forces anybody to buy new tech/products.

It's fine with me if new technology doesn't impress you. Just remember that the appliances/computers/cars/gadgets that you are currently using (and probably take for granted) all comes from advancement in technology.

Anyway, back to the topic. GDDR5 is planned to have lower voltages, smaller chips, higher frequencies and increased bandwidth......

WTf.....
DDR4 haven being popular, ddr5 is coming??? wasei

when u play nfs carbon with over 70fps u will feel the real speed..........
