Intel Core i5-520M vs Intel Core i5-450M vs Intel Core i5-540M

Intel Core i5-520M

► remove from comparison Intel 520M

The Intel Core i5-520M is a dual core CPU for laptops and clocks (due to the Turbo Mode) from 2.4 to 2.93 GHz. Each core is based on the Nehalem (Westmere) micro-architecture. Hyperthreading enables the Dual Core CPU to handle 4 threads at once (for a better usage of the pipeline). Compared to the faster Core i7-620M, the 520M features only 3 MB Level 3 Cache and a lower clock speed (CPU and GPU).

A feature of the new Core i5-520M is the integrated graphics card called GMA HD and memory controller. Both are on a separate die that is still manufactured in 45nm whereas the CPU die is already manufactured in the new 32nm process.

The performance of the i5 520M is on average faster than a Core 2 Duo T9500 and due to the Turbo Boost, single threaded applications run even better. Therefore, the Core i5-520M is as fast as high clocked Core 2 Duo CPUs and should handle most gaming and multimedia tasks well.

The 32nm cpu cores of the Westmere generation can also process some new instructions to accelerate AES encryptions.

The integrated Intel Graphics Media Accelerator HD (GMA HD) graphics card is known to be clocked up to 500-766 MHz and should be clearly faster than the old GMA 4500MHD. A GeForce 9400M (ION) should still be a faster (especially as Nvidia and ATI cards have a better driver support than Intel up to now). According to rumors, the GMA core will also use the Turbo Mode regulate the clock speed.

The power consumption of 35 Watt TDP (max.) counts for the whole package and therefore it is clearly better than the 35 Watt TDP of the Core 2 Duo T-series (CPU alone). Due to the Turbo Boost, the Core i5 more likely uses the TDP under load than the older Core 2 Duo CPUs. Without any load, the i5 uses noticable less power.

Intel Core i5-450M

► remove from comparison

The Intel Core i5-450M is a dual-core laptop CPU and clocks (due to Turbo Boost) with max. 2.4 - 2.66 GHz. Both cores are based on the Nehalem (Westmere) micro-architecture and due to Hyperthreading the processor is able to work with 4 threads simultaneously. The performance of the i5 is in the mid-range. The i5-450M is similar to the Core i5-520M, but the 450M does not offer AES functions.

A feature of the new Core i5-450M is the integrated graphics card called GMA HD and memory controller. Both are on a separate die that is still manufactured in 45nm whereas the CPU die is already manufactured in the new 32nm process.

The performance of the i5 450M is on average faster than a Core 2 Duo T9500 and due to the Turbo Boost, single threaded applications run even better. Therefore, the Core i5-520M is as fast as high clocked Core 2 Duo CPUs and should handle most gaming and multimedia tasks well.

Intel Core i5-540M

► remove from comparison Intel 540M

The Intel Core i5-540M is a mid-range dual core CPU for laptops and clocks (due to the Turbo Mode) from 2.53 to 3.06 GHz. Each core is based on the Nehalem (Westmere) micro-architecture. Hyperthreading enables the Dual Core CPU to handle 4 threads at once (for a better usage of the pipeline). Compared to the faster Core i7-620M, the 540M only has 3 MB Level 3 Cache and a lower clock speed.

A feature of the new Core i5-540M is the integrated graphics card called GMA HD and memory controller. Both are on a separate die that is still manufactured in 45nm whereas the CPU die is already manufactured in the new 32nm process.

The performance of the Core i5-540M is on average faster than a 2.8 GHz Core 2 Duo T9800 and in some benchmarks even faster than the fastest Core 2 Duo T9900 (e.g. 3DMark 06 CPU Score). Therefore, the Core i5-540M is a high end dual core cpu which should handle all daily work and gaming tasks. Only the quad core i7 CPUs can be noticeably faster at tasks that require four or more threads (e.g. rendering).

The 32nm cpu cores of the Westmere generation can also process some new instructions to accelerate AES encryptions.

The integrated Intel Graphics Media Accelerator HD (GMA HD) graphics card is known to be clocked up to 500-766 MHz and should be clearly faster than the old GMA 4500MHD. A GeForce 9400M (ION) should still be a faster (especially as Nvidia and ATI cards have a better driver support than Intel up to now). According to rumors, the GMA core will also use the Turbo Mode regulate the clock speed.

The power consumption of 35 Watt TDP (max.) counts for the whole package and therefore it is clearly better than the 35 Watt TDP of the Core 2 Duo T-series (CPU alone). Due to the Turbo Boost, the Core i5 is likely to use the whole TDP of 35 Watt under load and therefore can use more power than a similar specified Core 2 Duo. In Idle mode, the i5 uses clearly less power than the Core 2 Duo CPUs.
