Maybe i can add something yet to those general performance and fillrate subtopics:
I run the fine program named gpu-z and it gives some info about my
cheap gpu gt610 (worth of 50 dollars probably - i paid 50 for it but i am
from europe, but it seem that it is worldwide price )
Pixel Fillrate 1.4GPixels/s (shows the number of pixels that can be rendered to the screen in one second)
Texel Fillrate 5.6 GTexels/s (Shows the number of texels that can be
processen in one second)
Memory Type DDR3 (Please also note that GDDR3 doubles the avaliable bandwith of prewious DDR memory and that GDDR5 doubles the bandwidth od previous GDDR3 memory again)
Bandwidth 8.0GB/s (Shows the effective memory bandwidth avaliable between GPU and graphics memory)
Could maybe someone run gpu-z on his gpu and present me this info for his GPu it will maybe help me to clear some bandwith topics..
speaking about billions of triangles per second (which i doubt) iznt the general
drawing limited by those numbers - I mean if triangle is described by some say
80 bytes of data 8.0 GB/80 = only 100 M triangles per second not billions?
Could maybe also someone say to me why texel fillrate is 4 times higher than pixel fillrate ? (it seem to me that pixel and texel are just 4 byte vram)?
