    I'm just looking at texture fillrates on modern cards and is it just me but across generations is it becoming more and more wrong.

    especially as cards like fermi are released fermi will have a lower texture fillrate than the HD5870 since it will have only 64 texture units but those texture units are more powerful than on the HD5870 and the GT280 which both have 80, its been wrong since before then but this is just an example

    I think we need a new way to calculate it.

    uhm? please elaborate...

    fillrate = tmu clock x # tmus

    looking at cypress, it can fetch 4 texels per clock but filter only at a rate of 1 texel per clock. so texture fetch is 272 GT/s but filter is 68 GT/s.
