Problem je sto u GPU bound igrama se nece osetiti ubrzanje zbog veceg broja CPU jezgara iz prostog razloga sto je GPU ionako 100% zauzet renderingom. Naravno, u CPU bound igrama, mogla bi da se oseti znacajna razlika.Mislio sam na ovo:
Multithreaded Rendering is a feature which allows DirectX to be processed via multiple CPU threads. This means that a dual-, triple- or quad-core CPU can have a higher utilization across all cores than DirectX APIs in the past. Historically the OS would load up a single core for commands to the GPU, in essence creating an overload on the first core and under utilizing the additional cores. With only one core issuing commands to a GPU, we have seen CPUs hold back the potential performance of the GPU. With Multithreaded Rendering, DirectX will take better advantage of all the available cores. This should result in a better experience for the multi-core user because of a faster processing pipeline and increased scaling.
Iskreno, ima razlike, ali je mala. 1055T radi na 3.3 GHz sa 3 jezgra, sto je zapravo nekih 100MHz brze od X4 955.
Cudno je i to sto je dobitak izmedju 3 i 4 jezgra veci nego izmedju 2 i 3 jezgra. Procentualno gledano, 3 je 50% vece od 2, a 4 je 33% vece od 3. Takodje, Athlon bez L3 cachea na nizem kloku daje prakticno isti skor kao i Phenom sa L3 cacheom i 400 MHz vecim klokom. Nesto tu ne valja sa ovom tabelom. Ipak, BF2 realtime strategija je CPU bound igra, pa i otuda skaliranje sa vecim brojem jezgara.
