Nie je nahodou ten multi-sample este viac plynulejsi? A ten shader AA je v com lepsi?

Teda pekne nakopala 8800GTX. :8O: Aspon shadery ma dobre.

:roll:

vertex shader vykon je na HD 2900XT vyssi ako na GeForce 8800GTX, ale v hrach sa rozdiel "strati" ...

Velmi pekna recenzia na Pctuningu zamerana hlavne na technologicku stranku HD2900XT:

No-x nesklamal a odviedol kvalitnu pracu.

Nepride mi to nak extra.Zadna zminka o kvalite AF(je stejna jako u x1800/x1900) ani o kvalite AA.Ani o mega spotrebe.
Proste mi to pripada dost zvlastni...Her je tam navic dost malo:(.

Toto Radeon HD 2600XT 512MB GDDR4 (800/1100) by mohlo byt celkom zaujimave :8O:

Nie je nahodou ten multi-sample este viac plynulejsi?

prosim ? :roll:

A ten shader AA je v com lepsi?

vobec si ten clanok nepochopil ... Aby si ho pochopil, by si musel mat aspon zakladne vedomosti z danej problematiky - co ocividne nemas.

Nie je to "shader antialaising" - presne povedane, resolving je podla vsetkeho u R600 vykonavany pomocou shader ALUs.

Naco ten Tesselator je?

Pradedko R600 je R400 (jeho uvedenie nebolo zrusene kvoli dovodom, ktore uviedla ATi, ale kvoli tomu, ze bol na danu dobu slaby z hladiska vykonu)

uz aj R400 mal tesselator
Dalej Xenos
a teraz R600
-------------------------
R400: 4* Vec4 (4D)
Xenos: 3* Vec16 (5D)
R600: 4* Vec16 (5D)

aby nemuseli design zbytocne prepracovavat nechali tesselator v cipe. Okrem toho nosi so sebou R600 niektore nedostatky z R400 ...

spotreba HD 2900XT vs. ine karty:

The 2900 XT does match the GeForce 8800 series on image quality generally, which was by no means a foregone conclusion. Kudos to AMD for jettisoning the Radeon X1000 series' lousy angle-dependent aniso for a higher quality default algorithm. I also happen to like the 2900 XT's custom tent filters for antialiasing an awful lot—an outcome I didn't expect, until I saw it in action for myself. Now I'm hooked, and I consider the Radeon HD's image quality to be second to none on the PC as a result. Nvidia may yet even the score with its own custom AA filters, though.

techreport.com

What we found in our testing of ATI’s current Narrow Tent and Wide Tent filtering options was that enabling them caused textures to become blurry. This was plainly evident in every game we played. You will notice in our highest playable gaming section we simply ignored using Narrow Tent and Wide Tent filtering and just tested with the standard Box Filter at 2X, 4X or 8X AA. As a gamer I don’t want to enable an option that ends up reducing the entire scene’s image quality in my game. The point of enabling higher AA levels is to improve image quality, not decrease it.

heh raz tolko ako 7900GTX ta karta je ale hladna :8O:

Pradedko R600 je R400 (jeho uvedenie nebolo zrusene kvoli dovodom, ktore uviedla ATi, ale kvoli tomu, ze bol na danu dobu slaby z hladiska vykonu)

a co teoria o tom, ze nebol dostatocny vyrobny proces na to aby bol vobec schopny spravit taky cip?

uz aj R400 mal tesselator
Dalej Xenos
a teraz R600

ako prvy ho mal R200 (R8500), spominat R400 sa mi nezda velmi stastne kedze nebol vydany a bol iba na papieri, dovod viz vyssie

[crux2005]

R200 mal TrueForm nie programovatelny tesselator Ide o ukazanie podobnosti a toho, ze z R400 vychadza do velkej miery aj R600

R400 sa dal vtedy kludne vyrobit, avsak na dobu vydania by svojim vykonom nespravil vobec dieru do sveta

R400 je "pradedko" R600, preco sa ti to nezda byt "velmi stastne" ho spominat ?
