Intel core i7 640um 4m cache 1.2 ghz with 2.266 ghz max turbo frequency overclockable is definitely better because: - 4m cache is better than 1m cache - core i7 is technologically newer and more advanced than the T4500 - both have about the same performance level, but i7 saves more energy because of the 'UM' in i7 640UM, therefore longer battery life - i7 is overclockable, which means that the performance can be increased
An advantage of the Core i3 processor is that it is faster than previous processors such as the Pentium 4. A disadvantage is that the i5 and i7 are generally faster.
Of course Core i7 860. It's 4-cores, 8-threads processor while Core 2 Duo is only 2-cores, 2-threads. Moreover i7 860 got 8mb of Intel smart cache memory.
Currently, there are multiple processors on the market, namely the Via C-7, Intel's Core 2, Celeron, and Xeon series', and AMD's Athlon, Turion, and Opteron series'. processors of 2010 intel sandy bridge
i7 is faster
It think there is a difference of 40qm ! Lol
Intel core i7-920
the i7 920 has 2.67 GHZ with 4 cores and 8 threads, and the i7 940 has 2.93 GHZ with 4 cores and 8 threads. both can be overclocked easily. but if you are not planning on overclocking, the i7 940 is faster.
the i7 is better the i7 have 4 physical cores and 2 threads per core the core 2 quad have 4 physical cores and 1 thread per core. the i7 also have a technology called turbo boost to boost the performnce of single core apps
