The Core 2 Duo and Core i5-520M 2.4GHz are not from the same family of CPUs, so their clock speeds are by no Problematically, unless the two CPUsĪre from the same family, this can only serve as a general guide and nothing like an exact comparison,īecause the clock cycles per instruction (CPI) will vary so much. More important for gaming than the number of cores and threads is the clock rate. Run slightly older games fairly effectively. With a decent accompanying GPU, the Core 2 Duo and the Core i5-520M 2.4GHz may still be able to The Core 2 Duo and the Core i5-520M 2.4GHz both have 2 cores, and soĪre quite likely to struggle with the latest games, or at least bottleneck high-end graphics cards when running This means it will become a bottleneck in some demanding applications. The processor integrates very weak Graphics called Intel i5 520M, with 12 Execution Units, initially clocked at 500MHz which go up to 766MHz, in Turbo Mode and share the L2 Cache and system RAM with the processor.īoth the processor and integrated graphics have a rated board TDP of 35W. It offers 2 Physical Cores (4 Logical), initially clocked at 2.4GHz, which may go up to 2.933GHz and 3MB of 元 Cache.Īmong its many features, Turbo Boost and Virtualization are activated.
Intel's CPUs have varied widely in power consumption according to clock rate, architecture, and semiconductor process, shown in the CPU power dissipation tables.Ĭore i5-520M 2.4GHz is a middle-class mobile processor based on the 32nm, Nehalem architecture. The Core microarchitecture provides more efficient decoding stages, execution units, caches, and buses, reducing the power consumption of Core 2-branded CPUs while increasing their processing capacity. The Core microarchitecture returned to lower clock rates and improved the usage of both available clock cycles and power when compared with the preceding NetBurst microarchitecture of the Pentium 4/D-branded CPUs. The introduction of Core 2 relegated the Pentium brand to the mid-range market, and reunified laptop and desktop CPU lines, which previously had been divided into the Pentium 4, Pentium D, and Pentium M brands. The single- and dual-core models are single-die, whereas the quad-core models comprise two dies, each containing two cores, packaged in a multi-chip module. Core 2 is a brand encompassing a range of Intel's consumer 64-bit x86-64 single-, dual-, and quad-core microprocessors based on the Core microarchitecture.
