ATI Radeon HD 4000 Series discussion

Hi Perkam, can you lock the thread for 24 hours? We'll not have any new info in that space of time.


Ok, I'll just come out and say it, OBR, you're not that smart


...creating extra site traffic while spammers are posting...so low you have gone...what's up with u?

[natty]

to natty: No, he just made a mistake and he set it straight afterwards, there are however some other people whom deserve a vacation.

he has a habit of doing similar things, he needs a vacation

If I could I would

But people really need to get over the OBR thing. It'll come when it does. OBR gave us a little tease and frankly, I can say with certainty that even the XIPs and XLs are EXTREMELY tight lipped about this stuff, so I'm not too surprised with OBR's decision, as AMD calling him is perfectly plausible considering the amount of secrecy over the subject.

You can't blame OBR for being inexperienced with this kind of thing, you need quite a bit of restraint to stop you from posting GTX 280 SLI benchies. You can ask Kingpin about that when the cards release and Futuremark servers go down the drain

Sounds like the 4000 series are going to be the new golden boys of GPGPU applications. It would be nice if AMD hit the ground running with this release.

I agree, just a bit miffed at the situation...OBR, well, I could care less what he does. Just seems strange to have a jump in traffic at the same time that spammers are posting, when they haven't been able to in the last few days.

Don't get me wrong, I do not blame OBR, but his timing is very poor!

Anyway, as a lesson to others, please don't post "hints" or "teases", just post numbers and nothing else.

[Luka_Aveiro]

LOL @ everyone who believed OBR was REALLY going to post anything.

[perkam]

Let's back to topic ppl !!

(We might see 30k '06 on air with some setups and 35k++ with LN2 :p)

Only with Nehalem, as 3DMark06 is now a CPU bound bench

[003]

seems they got problems with the gddr5 memory... only 1800 mhz clock (slowest bin)?

Thats without the DDR taking effect and making it 3.6GHz effective.

Let's wait and see

The only concern there is the drivers...which need time to mature, especially for Nvidia's new arch. ATI will try to cripple its performance early on and release better drivers once the 9900s hit the market.

i knew that, its still slow for gddr5 (goes up to 2,25ghz), i expected more than the lowest bin gddr5, maybe we see higher clocks in the X2 version.

[Extelleron]

That's still the lowest GDDR5 bin.

It's probably not available yet, but GDDR5 is supposed to go up to 4.5-5GHz.

As someone else mentioned, likely the supply of higher bins is not so great yet and also the cost would be higher if they used faster modules. There probably isn't much of a need for more bandwidth anyway, so it would just be a waste. The 4870 will still have more bandwidth than the GTX 260 (115.2 GB/s vs. 112.0 GB/s).

[Xello]

They can disable or set the frequencies. That is how they split up the main chip into many fragments which is usually called market segments, that means the same chip can make many derived products from it like 4850, 4870 and 4870x2.

Metroid.

What will be interesting to see is just how much of a difference the GDDR5 will have over the GDDR3. If both GPU's were at the same clock speed just how much of a difference will the extra 900mhz on the member make (2ghz vs 3.6-3.8ghz effective).

The 4850 uses lower bandwidth due to 256 bit-wide + GDDR3 and frequency, so that should imply on a lower performance than 4870. The 4850 probably could not have shaders being disabled due to performance issues and competition. The best bet was to keep its design and performance being controlled by its bandwidth and frequency. A 4850 overclocked with a GDDR5 would be interesting.

Metroid.

This is what i mean - if the 4850 and 4870 are using the same core, with the same number of SP's, is the memory bandwidth of the GDDR5 alone going to increase performance of the 4870 much above the 4850? Isn't that like comparing a 512mb current card to a 1gb or 2gb version (i believe there are 1 or 2 kicking around), whenever you see benches on those huge memory cards there is virtually no performance gain with the extra bandwidth, even at high resolutions.

Sounds like the 4000 series are going to be the new golden boys of GPGPU applications. It would be nice if AMD hit the ground running with this release.

Hmm, nothing sounds like anything to me personally so far, not until the launch day reviews! No harm in some speculation i guess.

[tenebre]

heh... looks like I missed the show...
OBR and everyone else.. NEXT TIME YOU HAVE PRE_RELEASE OR SENSITIVE INFO TO POST DO IT ANONYMOUSLY OR STFU AND DON"T MAKE PEOPLE WAIT FOR HOURS TO TAKE YOUR

Nah.
That "1800m" is DDR-1800 (900MHz). But since GDDR5 is quad data rate 900MHz GDDR5 acts effectively as DDR-3600.

In simple words if there is a need, it will be used. If it does not have, likely can not be used.

[Kai Robinson]

Seriously - get over it guys....

[Sly Fox]

I'm envious of you guys that are clearly "in the know."

I'm sure everyone who this includes has done loads of work on their part to earn that right... Reviewing products, offering insight to the vendors, etc. Just wish I had the money and connections to get into that stuff myself haha. In any case, I have a feeling we'll probably get things leaking out more and more as the date draws near... With all the cards Nvidia and ATI will likely throw around for benching/reviews/teasers... Someone is bound to break NDA eventually.

Extra bandwith will not be superfluous especially on a high resolutions.

i read the last few pages of this thread and almost puked. honestly some people make me SICK. ORB was going to give us the privilege of seeing some more info on it but re thought things a decided to play it safe. and then many people come and flame the crap out of him for not showing anything???? WTF??????? all of you people saying that ORB should get banned or ORB should die need to GET A GRIP. it's ONLY a freaking Video card!!!!! and we will have reviews shortly. the man tries to do us a favor and it does not work out so we spit in his face????

my gosh people. some people need to calm the heck down. so what if we have to wait another week or 2 to see some numbers on a MIDRANGE AMD card?? that's worse than crying of split milk. i am not impressed at all.

looks like the one that needs to calm down is you

[[XC] hipno650]

i did not get all mad because of a Video card i got mad at issues that really matter in the world, like treatment of human beings for example?

is hatting man because he can't deliver on a FAVOR right?

and some of those posts about trying to get him banned? some people have obviously not been here long enough to know what he contributes to the forum. especially when it comes to launches and reviews. sure some things he says can be a bit biased but he is one of our only sources of pre launch info. and i honestly can't see him posting any leaking info after the responses he got.

Its only a video card...fokkers!

Some of you need to get out more often.

I go out a lot..... to the kitchen and the bathroom
