Does 4870 and 4850 have 40 TMU's

[EastCoasthandle]

That is the question for this thread. I am reading a lot of mix results about this.
1st the absolute of "40TMUs confirmed" statements
2nd the 4850 may have 32 TMUs when the 4870 has 40 TMUs
3rd both 4850 and 4870 use only 32 TMUs

Now IMO, the results I've seen so far on the 4850 just doesn't impress me if it is using 40 TMUs. I would expect results higher then what I've seen so far. This is why I believe that the 4850 is using 32 TMUs. However, if a driver problem exists then that could explain the results so far. In all, it's not very clear to me and, I have not found any information on Rops.

Your thoughts?

^^ gibberish. i want to learn. plz break it down.

TMU = Texture Mapping Unit, pretty much 40 TMU's mean the GPU can place 40 textures per clock in laymans terms

sigh more speculation threads, can't we just wait and see? I eman we're hearing anything from a minimal increase over the 3870 to a monster that will crush the gtx280

rumored specs
#1
16 rop's 480 stream processors by 96 shaders with 32 tmu's and 256-but gddr5

#2
16 rop's 480 stream processors by 160 shaders with 32 tmu's and 256-bit gddr5

#3
16 rop's 800 stream processors by 160 shaders with 32 tmu's and 256-bit gddr5

#4
16 rop's 800 stream processors by 160 shaders with 40 tmu's and 256-bit gddr5

#5
32 rop's 480 stream processors by 160 shaders with 32 tmu's and 256-bit gddr5

#6
32 rop's 800 stream processors by 160 shaders with 40 tmu's and 256-bit gddr5

#7
32 rop's 800 stream processors by 160 shaders with 40 tmu's and 512-bit gddr5

at quick glance 5-7 seem ridiculous. 2-4 are hopefuls and 1 is a worst case scenario.

Did you notice how, with the release of the FireStream 9250 GP-GPU, they avoided giving ANY tech specs. AMD are being very secretive for some reason. Perhaps yields are low... and they are hoping to get production fixed so that they can release fully working, rather than BIOS restricted, with pipelines/shaders turned off?

It's really odd why they are so secretive even after nv official released their cards.

Very interesting, can't wait for the NDA to lift.
