AMD To Launch RV770 On June 18th

Be interesting to see if ati will actually let third parties choose their own cooles and clocks. I remember when the x1900 was released and people complained about the cooler ati said that they were gonna ship the cards without coolers and let third parties design their own. Pretty sure that never happened, there was the HIS version but they usually do make their own versions of coolers eventually anyway.
 
Even if it is makers discretion I think they will offer a reference design just incase, for the cheaper brands to use.

I will like to see what custom cooler XpertVision choose to use, they usually come out with a half decent one.
 
More 800 shader rumors.

http://www.fudzilla.com/index.php?option=com_content&task=view&id=7805&Itemid=1

Radeon HD 4870 and Radeon HD 4850 will both have a whopping 800 Shaders. The previous generation had 320 and as you can see we are now talking about more than double the number.

ATI will market its cards as TeraScale engine capable and as we’ve suggested before RV770 will reach 1 TeraFlop processing power.


With 800 Shader processors at 625MHz the Radeon HD 4850 can reach 1000 GigaFlops or 1 TeraFlop while Radeon HD 4870 at 750MHz would each 1.2 TeraFlop. People have reported that the card will end up with 480 shaders, but the number is bigger. The big issue for ATI is that its 480 Shaders might end up way slower than Nvidia's 240. This was always the case in the past and Nvidia's Shaders are usually clocked at higher than GPU frequency.

We believe that ATI’s Shaders were quite transistor cheap as the RV770 die won’t be much bigger compared to RV670 and these numbers actually do bring some optimism.

I really do hope ATi have fooled everyone and snuck out a card with 800 shaders.
 
What's the rumour on the price of these cards?

edit- sorry, I just saw lightnix's post.............too much beer last night. :rolleyes:
 
Not gona look very good though still are they if they do have 800 shaders, as they not competing with the GT00's supposedly, so those will more than likely still thrash em, and with far less shaders to boot.

Yeah but if a GTX280 is £460 and the 4870 is £200, the GTX280 ought to hammer it.;)

But, we'll soon know.

If the 4870 gives a good enough boost over my 8800GTS I might even be tempted myself.

Personally for £460 the GTX280 just isn't going to give me enough boost for the huge amount of extra money.

I might as well buy two 4870's and have them in crossfire or wait for the 4870x2.

A bit of speed editing there Loadsa? ;)

I dont think you can directly compare shaders anymore.
ATI and NVIDIA approaches are very different.

If they are hitting 1 teraflop for the 4850 and 1.2 for the 4870 that not bad at all but it depends how the measuring the teraflop i guess if it is theoretical and just marketing p.r again and not real performance in games.
As numbers can be made up to mean almost anything
 
Shader power isn't everything, it seems nVidia is coming out with a much more balanced card (much more fillrate in everything), whereas AMD are going for lots of shader muscle and bandwidth. AMD's game plan could well be to sell more based on upcoming GPGPU applications, with far more raw shader power.

Edit: Just to clarify, what I'm saying is AMD aren't at all lying about how much shader power they have, it's just nowhere near as important as people are making it out to be. I think this is best illustrated with the 9600 GT, which has little over half the shader power the 8800 GT does, but isn't far behind it at all.

You could be right but ati needed to up the shaders anyway we need to wait and see,ati had the bandwidth with their 2900 so it makes sense to go 256 with gddr5 with 55nm.
