Although the GTX 680 has a higher theoretical rasterization rate than the GTX 580, the GK104 GPU has only half as many setup and tessellator units (aka PolyMorph engines) as the GF110. Despite that fact, the GTX 680 achieves twice the tessellation performance of Fermi. The GTX 680 even exceeds that rate in TessMark's 64X expansion test, where it's nearly three times the speed of the Radeon HD 7970. We doubt we'll see a good use of a 64X geometry expansion factor in a game this year, but the Kepler architecture clearly has plenty of headroom here.
Prior to Kepler, for the GPU to reference a texture, it had to be assigned a “slot” in a fixed-size binding table. The number of slots in that table ultimately limits how many unique textures a shader can read from at run time. Ultimately, a shader was limited to access of just 128 simultaneous textures in Fermi (which aligned with the API limits of DX11).
With bindless textures in Kepler, this additional step isn’t necessary: the shader can reference textures directly in memory, making binding tables obsolete. This effectively eliminates any limits on the number of unique textures that can be used to render a scene: over 1 million unique textures are possible.
Besides dramatically increasing the number of available textures, another added benefit of bindless textures is reduced CPU utilization

Upravo tako. Ogroman broj entuzijasta koji kupuju svaki nov model koji se lansira ce i ovaj kupiti, tako da neko preterano variranje cena i ne treba ocekivati. Bice korektno ako nasi primene konvertor valuta tj primene stvaran kurs dolar/evro.sve iznad 300 USD zajedno cini 7%.
Super, dobili smo malo bržu karticu koja manje troši, za manje pare. Koju će da ima šaka ljudi sa ovim cenama, isto kao i AMD-ov pulen. Ali su zato smehotresni komentari koje vidim ovde o impending doom-u AMD-a i njihovih "junk" kartica. Malo se preteruje.
Vec godinama se svodi na isto, amd izbaci najjacu single gpu, nvidia malo kasni ali izbaci jacu, cene se sredjuju iz meseca u mesec a odredjen broj ljudi se ispalio kupovinom jer su morali prvi da imaju najnoviju graficku :d iako za to i nema neke prevelike potrebe
Koliko je vremena bilo potrebno da 6850/70 spadnu na 150 i 190e? E pa toliko ce verovatno trebati i sada za 7850/70. U sustini ocekivano.. a u medjuvremenu se fanovi kolju i prepucavaju iako za to nema razloga al dobro..
