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??

http://www.digitimes.com/news/a20070607PD215.html

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..........

above 50fps is consider good already...n i dun think nid 70fps to feel the real speed

DDR4 , the digit '4' means die in some asian believe.. LOL.. tats y some people skip terus to DDR5

it oculd be rm3k or rm4k??

ya over 50fps is very smooth already
70fps is to avoid when car crashing drop fps.........

good question and the answer is nope.
GDDR4/5 is just an advancements to memory in terms of efficiency and bandwidth.
just like DDR2->DDR3 lah, minor improvements but it runs at reduced voltages...for us to overclock some day haha. joking

hm...so fast..so no need to fast grab the DDR4 GC but wait patiently for the DDR5 to come out

so far..GDDR3 is already enuf

I from seremban...
I m working in a computer shop
I wander coz my shop doesnt even sell DDR 3 RAM...
=.=" But DDR 4 n 5 is emerging...cant believe
Wat a downgraded state I m staying at
hahaha....^o^
How much it cost for DDR3? for 512MB...jsut asking
Wander how much it will cost

so fast la..

around rm350-rm1000?


the x1650 with ddr3 256mb perform better than 7600gt?

x1650pro<7600GT<x1650xt (correct me if i'm wrong)

Wah~~~ so costly ar?
=.= But actually wat is RAM for? Actually purpose
Still not clear of it...n how to diffrence its performance?

this thread is talking about VGA ram
we'r not talking about the pc RAM here
pls make clear of that

maybe gddr5 will have lower voltages thus produce less heat so maybe easier to cool down the memory???

Oh...okok I didnt see ma >.<
Wat i see is DDR4 up there....
if that DDR3 Graphic Card my shop got le
lolx...But what does tat matters?

edited..wrong posting

yup..some sort like dat la..it it power efficent and more speed than the lower grade

---

Added on July 21, 2007, 2:01 amit matters a lot la bro..for example..if we compare 7300GT DDR2 with 7300GT DDR3...the GC with DDR3 is far more powerful than the DDR2 version..so here is the proof to show that it really matters

This post has been edited by verz84: Jul 21 2007, 02:01 AM

funny thing is in d article it says qimonda will be using d 75nm process when 2900xt's r edy using 65nm manufacturing process..funny..want 2 use ddr5 tech but use older manufacturing process

So far like DDR3 for desktops, it just gives a nice, warm placebo effect.

Do the new cards need a new type of RAM? No. They haven't even pinned down GDDR4 latencies with better chips yet, what'd you expect from GDDR FIVE?

For midranges, nVidia might be halving its 8800's 320bit bus for a little better bandwidth while ATi might go X1950 of all sorts and use 256bit with higher prices.

For graphics purposes, the slight increase in latency doesn't matter much. The important thing is improving bandwidth, because GPUs are made to hide latency and maximize bandwidth. GDDR5 doesn't seem like a huge change, they're not doubling the internal prefetch IIRC, so i don't see the latencies increasing. It's something like GDDR2->GDDR3, some refinements, but it could go a long way.

people (consumer) wait for new graphic cards, not new gDDR chips

gDDRchips wont affect ppl like pc noobies(mean they dunno the diff between gc)...for them ore memory means better.....gddr3 performs welledi..why for pay more?

yea..agree..GDDR3 is already very good

By that time PCIe 2.0 is a must bcoz already bandwidth bottleneck on PCIe 1.1.

that means more money, if it's like that I rather stick to GDDR3 for a while

It seems the RAM engineers are making breaktrough consistantly, I wonder will they ever hit the wall.

whenever that happens, we'll be screaming n shouting for newer products

i rather stick wit my gddr3 rather then spend thousand to upgrade to gddr5..myb will upgrade when gddr3 getting obsolete...

I will only go for it when it becomes mainstream hardware.
It's kinda expensive. I couldn't afford chasing new technology by spending huge sum of $$$.

Bandwidth is important , like GDDR3 -0.8ns ( use on 8800 Ultra ) had 2.5Ghz DDR , but GDDR5 will start at 3.5GHz ~ 4GHZ DDR . Just compare and you'll see who is faster . GDDR4 only ( until now ) used on 1 product which is Radeon X1950 XTX , so pity

Qimonda ships first GDDR5 memory devices!

Still a bit to wait but here's some more news..... http://www.tgdaily.com/content/view/34659/118/

Looks like they struggling to be the first to bring out GDDR5 to the market. So they really skipped GDDR4 huh?

becuz 4 is not a good number for Asians especially our main manufacturing country...

Personally i think having GDDR5 is kinda overkill
GDDR 3 already manage to play all those high resolution games up to date.

"up to date" is the key phrase here. Some of us plan to live a little longer.

There's nothing wrong with technology pushing forward. Granted that it is already at a tremendous pace but I should think that any new technology will be utilized to the fullest and become "old tech" not long after that.....

Ya ya, I want to live long enough to see GDDR20.....

huahuahua
go eat vitamins alot bro
dun smoke
eat well
and execise
hope u can make it

i dun care the ddr1/2/3/4
as long as the output is good
plus the price is affordable
i go for it

Haven't see any GC that uses GDDR5.
Even finding GC's that uses GDDR4 is kinda hard.

Errr... sample volumes just went out la..... products with GDDR5 only coming out H2 2008. See post #51 for the link.

Wei, careful what u wish for. Supposing a new 1 comes out every year, and now already at GDDR5, u only haf 15 years left!

Won't be so fast la. If not because of Qimonda, GDDR4 would have been mainstream for another couple of years. By the time GDDR20 comes out, I'll probably be 60 years old. At that time, if I can game with GDDR20, I'll die a happy man!!!

very fast lo...RAM...
...
wonder the next gen gfx card will have these babies...

really wonder if mid end users can see the diff between ddr3 and ddr4...any of you guys actually tested these ddrs out to see the differences?? just wanted to know..as sometimes the suppliers promote but the diff not so much but users pay through the nose..

If you look at the DDR3 & DDR4 you think it look ahead but the speed is not very much in different. It depend on many factor, not just the RAM itself. Example, an ATI 2600XT DDR4 lose to NVIDIA 8600GT DDR3 in most of the games benchmark so you know there is not much different actually, not now maybe 1 or 2 years later when those software made to recognizes it. If comparing DDR2 to DDR4, yes there is a lot of different.

err... really...?

actually up to date games still lags in my current rig which i spent almost RM4k to build...
if u r talking bout o9 games... please don compare cuz i can play them wif Intel GMA950... lowly hardware for lowly software...

seems ATi failed to benefits GDDR4 on their current gc? tried my friend's hd2600xt ddr4 but seems my x1950pro is much better

Friends of mine also say that GDDR4 really not nesessary at this moment if not nvidia already use GDDR4 on it 8800GT.

your friend...is an idiot.dont listen to him from now onwards...

GeForce 8series Wiki

So... what's the wiki link for? Where does it prove your point?

Well, do you realize that quad core is also not necessary for most people at the moment? If not for folding, I wouldn't want a quad core now anyway.....

Besides, what is the capability of current GDDR4 in ATI's 3870? Did somebody mentioned 2.6Ghz.....

Samsung already debut world's fastest GDDR5 can operates at whopping 24GBytes/s. Thats really crazy. By that time already can play crysis at 60fps++ ultra high.

Huhu why no DDR5 in RAM.
Anyways DDR and GDDR is different.
For solid evidence, ATI uses GDDR4 for their cards as Nvidia just stay with GDDR3.But the result is nvidia still pawn the GDDR4 in term of performance.
But I'm not saying GDDR4 is not good.Just maybe the performance not optimized by ATi.If nvidia to use GDDR4 maybe is good.But considering nvidia haven't use a single GDDR4 for ther 8 series card,just make me wonder why...

maybe its a guide or somekind of enlightenment for some... errr.. i dunno, really whats the wiki for?

Hmmmm.... looks like Hynix is also skipping GDDR4 and jumping to GDDR5..... http://www.xbitlabs.com/news/memory/displa...mory_Chips.html

Quote from above article "With its improved speed and power characteristics, GDDR5 is projected to succeed GDDR3 and dominate the graphics DRAM market from the second half of 2008."

It's for political reasons rather than technological.

Political? How to say?

i suppose they are still new with the GDDR4 juz like they shift one 90nm to 65nm, it takes some times for them to be mature..

samsung is the one who is releasing it... Change your mobo ... sell your gc....

Some updates on GDDR5 : GDDR5 in production

Hynix Semiconductor Introduces 7GHz GDDR5 Memory!!!

http://www.xbitlabs.com/news/memory/displa...DR5_Memory.html

I wonder how you cool it.

Maybe we'll have a peltier stuck to these RAM modules, while the GPU itself merely has a 128/256 bit bus.


Nah, GDDR5 needs to get cheap first. 4/5Ghz modules at 1GB capacities seem to be making the 4870 less attractive vs the GTX 260, so we need that to come down first before making the next moves.

On the other hand, a 192 bit bus, 768MB 5/6Ghz GDDR5 sounds great for a new mid-high chip.

The lower voltage would help, I guess...... maybe they will introduce heatpipes for the GDDR5!

Any picture of the actual product!?......yet?

last time i used 7300gt...256mb ddr2 and 128mb ddr3.
ddr3 wins..so i think higher ddr give at least a slight increase in performance or sometimes maybe negligible
