ja sam bio ubedjen da je u pitanju bila moja naklonost ka nVidia ali posle 5870 mi je aero bio primetno brzi sa 285. No mislio sam da tripujem...

Tripujes i dalje, to sto je neko pronasao neki bench program u kome nvidia radi brze od nove serije ati-a nije odma i sveto pismo, to su slamcice.
Voleo bi da mi neko u praksi dokaze tu razliku ...

Update (1/26/2010): With preliminary research into our 2D performance analysis, AMD reports back with the following:

* Tom’s Hardware has tripped over a workload area (2D lines, etc.) that we have not optimized yet.
* Until this new benchmark, we have not seen any other applications that are bottlenecked by this path, and hence have not focused on it until now.
* Our initial analysis has shown that we have no hardware limitations in this area.
* We now have our driver team engaged to optimize this path and will release a new driver to address this workload as soon as possible.
* We have already found an easy way of increasing our performance greatly, and are now going to try and schedule this in a future Catalyst (need to code in production, validate, ensure it doesn’t break anything else, etc.).
Sta to ustvari znaci ? da losije radi sa Auto Cad-om, ArchiCad-om, Photoshop-om ?! gde je ova primena izrazena u praksi, to mene interesuje.

Pazi mene ovi testovi nesto mnogo neinteresuju, zanima me u praksi sta to znaci.
A ova recenica mi je bila dovoljna ...

We must also point out that this applies not only to our synthetic 2D benchmark, but also to various other real-world programs we used for our testing, including AutoCAD, as well as Corel Draw, Adobe Illustrator, Photoshop CS3/CS4, Microsoft Publisher, PowerPoint, and more.
Ono sto sam ja licno primetio, je da x64 verzija photoshopa radi sa ati stream-om, i radi neverovatno brzo, ali ima ogromnu manu, a to je ne mogucnost koriscenja dodatnih pluginova, koji za sad rade samo na 32bitnoj verziji, barem oni koje sam ja bio u mogucnosti da isprobam.

Ako zaista ljudi imaju problema u ostalim programima u smislu sporosti, laga i glicheva, u sta cisto sumnjam, da je toliko drasticno i dramaticno, onda je ovo OGROMAN problem za ATi, samo jos jedan u nizu lose optimizacije drivera.
A da je toliko velik problem u praksi, siguran sam da bi se do sada digla mnogo veca frka oko ovoga ... jer realno to bi i zasluzila.

ja samo kazem da je razlika meni bila primetna. ali sam mislio da umisljam i preterujem.

Iskreno receno nisam nesto ni pokusavao da merim odokativno. 2D mi je radio OK. Da nije vec bih prijavio u 5850 threadu. Medjutim, ovaj Tom2D radi mnogo brze na NV. E sad, meni je WEI (Windows Experience Index) za grafiku bolji na 5850 nego na 285 u oba slucaja (gaming i desktop).

Samo hocu da kazem da mi je dosta sintetickih testova, ako nesto ne radi kako treba, onda cu to i da kazem.
Imao sam plavih ekrana, imao sam cak i jedan grey screen of death sa nekim beta driverima, AA je vrlo diskutabilno odradjen, shimmering koji mi je bio primetan u dragon age itd ... kad je nesto ocigledan problem, ja cu ga reci i priznati, al isto tako cu reci da nemam problema sa 2D u Win7 x64 sa Aero enabled, imam cak i Objectdock instaliran.
Dal je nova ATi serija sporija u nekom 2D testu, ok, evo dokazao Toms da je sa tim sintetickim testom sporija, ali na sta to u praksi tacno i koliko utice ... ako ispadne da u realnom radu ATi korisnici nisu na nikakvom gubitku sto se brzine tice, a opet u idle vuku 35W i manje, drze temperaturu na "minimumu" i pri tom su necujne, onda je to po meni skroz ok, u suprotnom, naravno da ce ovo biti jos jedan veliki minus za ATi driver ekipu. :wave:
