MFA diyor ki, ve hatta ben de diyorum ki, 6800 serisinin safi tessellation performansı 5800'lere göre arttı fakat Heaven testi komple bir test, sadece tessellation yapmıyor. Bütün sahneyi çiziyor yani shader'ları olsun texture'lar olsun gölgeler bump'lar efendime söyleyeyim başka bir sürü şey. Tessellation bunlardan sadece birisi. Tessellation toplam iş gücü isteğinin %20'sini oluşturuyorsa, tessellation'da %50'lik bir hız artışı size toplam olarak ancak %10 bir performans artışı getirecektir örneğin.

Normal tessellation eğer tess. factor 16'ya denk geliyorsa bu, tabloya göre, tessellation performansında %35'lik bir artışa denk geliyor. Tessellation performansının %35 artması demek, içerisinde tessellation olan her sahnede performansın %35 artması demek değil, o tess. hesaplamalarını yaparken performansın %35 artmasıdır.

Yukarıda yazdığım örneği tess. açınca düşen performans açısından göz önüne alalım ve %20 değil %30 diyelim. Buna göre %40'lık kısımda %35'lik artış, size toplam %10'lük bir performans getirisi sağlayacaktır.

Bu da normalde 5850-5870 arasındaki 6870 performansını ancak 5870 seviyesine çıkarmaya yetiyor.

GTX 480'in HD5000 serisine göre olan ham tessellation performans avantajı %200 filan olmalı. (edit: ahaha valla yukarıdaki tabloya bakmadan yazdım, hakkaten %200müş normal ayarlarda )
