The ATI Radeon 5XXX Thread

and about 5870 beating gtx295...
4870 to 4870x2 scaling is 55% of a 295 to 90% of a 295... considering that a 5870 appears to have the same hw specs as a 4870x2 but isnt castrated by having it on 2 chips and there is no overhead, id expect a 5870 to be around 110% of a 295 like a 4870x2 would be, if it wouldnt have any overhead caused by being based on 2 chips... and thats assuming the 5870 comes clocked at 750mhz core and 3600mhz mem... according to the rumored specs it looks like like 800-900 clocks for the gpu and 5000mhz for the mem... so it will DEFINATELY beat the 295...

I think equaling GTX295 shouldn't be a problem for 5870 specced as rumor says. Remember that for the first time in recent ATi history we are getting not only 2xShader count, 2xRBE but also 2xROP. All this on one die instead of 2 dies. On top of that better scheduler plus other tweaks will mean much better scaling compared to older 4870X2 (no CF overhead). The only limiting factor can be memory bandwidth in some cases.

That last bit was exactly what I was going to say to saaya.
We are doubling, if not more than doubling, almost every aspect of the chip but yet they are only, as far as we know, increasing the bandwidth by 39% (160 vs 115GBps).

Will there be a "CypressLE" or something like HD4830(RV770LE) had 160 shaders disabled to 640 shaders instead of 800?

Eventually. Remember, it isn't AMD/ATi's strategy anymore to rely on salvaged parts.
The last few generations they have been releasing those salvaged parts, seemingly, when the GPU is EOLed, when they know they have a decent stock and need to clear inventory w/o worrying about too many more salvaged parts flowing in.
