oya lupa bilangin, V3 itu 2D/3D dan gak ada rencana buat support SLI,
mengenai mtex vs mpix, bedanya gua juga gak yakin
kalo fill rate dihitung dgn definisi pixel = 1 titik dilayar (def konvensional)
brarti tergantung scene 3dnya, satu poligon ukuran 100x100 titik
bisa saja jadi lebih kecil (miring thd layar proyeksi)
dan overdraw,
karena masih pada pake traditional rendering dalam arti
digambar semua shg yg ternyata tidak kelihatan akan tertimpa?
tolong dijelaskan lebih lanjut...
supaya lebih mengerti kalo lihat spec 3d...
atau mungkin pixel = texel tapi khusus utk yg single-texturing??
kalo ini rasanya lebih pas deh ;)

>Gue ngga tahu kalau itu news terakhir ..
>terakhir gue baca2 sih.. chip baru ini Banshee2 ..
>kenapa ngga voodoo3 ?..karena bukan dedicated 3D .
AFAIK, v3 itu yg didemoin di Comdex,
trus baru muncul isu/gosip, v3 itu sebenarnya b2
soalnya kan v3 itu 2d/3d, padahal v1 & v2 3d only
tapi kalo ternyata ada b2 beneran...
gua gak tau deh...
v3 itu sendiri ada 2 versi
v3 2000 dan v3 3000
yg 3000 itu lebih kenceng...
kalo ada b2 brarti = v3 1000???
