Hans, <This is the reason that I guess that the Timna die size will be twice as big as the PIII on the same process. somewhere in the 200mm2 area.> One way to estimate the die size of Timna would be to look at the die size of the 810 chipset's north bridge. That thing consists of both the memory controller and the integrated graphics. I also believe the north bridge is made on the 0.25u process, so if you can take its die size at 0.25u, divide it by two (shrink to 0.18u), then add 85 mm2 (my estimate for Coppermine-128), you can get pretty close to Timna's die size. Unfortunately I don't know how big the 810 north bridge is. I can't believe it would be any bigger than the low 200's, since the thing is supposed to be low-cost. That could mean Timna would be just under 200 mm2 in die size. And 200 mm2 isn't bad at all, considering the integration. Tenchusatsu

Hansdevries, Re: "die size of graphics" I suspect you are a tad clueless or missing the point. A VGA core taks about 20K gates plus small ram and RAM DACS it is <5mm2 in core area. Modern cores may take 10-20mm2. Where the area is large ie 100mm2 is taken when folks are doing very high end graphics chips such as Geforce etc. The class of core on timna will be modest not leading edge and will used shared memory between system and graphics. Your guess of a 200mm2 core size for timna is WAY OFF IMHO. regards, Kash
