Sony Vaio VPC-F12Z is the strong quad-core processor, Intel Core i7-740QM, has a relatively low basic clock rate (1.73 GHz) but a high turbo rate (2.93 GHz). It has a 256 KB Level 1 cache and a 6 MB Level 3 cache. The TDP is, alike the sister model 720QM (4 x 1.60 GHz, Turbo 2.8 GHz), 45 watts.
As the i5 processors, the i7s have Intel’s Turbo Boost. That means a dynamic overclocking depending on application requirement. The single processor cores are overclocked fully automatically. This way, applications always have the momentarily necessary capacity available. Thus, the old discussion about multi or single core applications isn’t any longer important. Both application types are simply supplied perfectly.
Moreover, there is hyperthreading. This feature complements the four physical cores with four virtual threads. Therefore, applications can compute up to eight threads. In this case, not all eight clock with the aforementioned 2.93 GH7 (that would burst the TDP limits), but rather with 1.9 GHz. Only when one core takes over the entire calculation effort does its clock rate increase to the maximum of 2.93 GHz. This isn’t common in reality, because some background programs are always being processed by other threads.
The system is supported by an 8 GB DDR3 RAM (PC3-10700, 1333 MHz). This memory type provides for a very good memory score of 3911 points in PCMark Vantage. The 8 GBs is on two RAM slots, which are furnished with these. The 64 bit operating system, Windows 7 Home Premium, can manage this large memory capacity.
