ATI Radeon HD 4000 Series discussion

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

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.

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.

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.

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.

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

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

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

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