Intel Core i5-450M vs Intel Core 2 Duo T9500 vs Intel Core 2 Duo SP9300
Intel Core i5-450M
► remove from comparisonThe 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.
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 2 Duo T9500
► remove from comparisonThe Intel Core 2 Duo T9500 was a upper middle class dual core CPU for laptops at the time of introduction. It was intended to be used in the Santa Rosa platform due to the 800 MHz FSB. The T9550 is only slightly higher clocked but offers already a FSB1066.
Due to the relatively high clock speed and 6MB Level 2 cache, the T9500 offers enough performance for demanding games (in 2009) and applications.
The T9500 uses a Penryn (Montevina Update) core that features 2 integer units, 1 floating point unit, 1 load unit, and 1 store unit in a 14-stages long pipeline. Due to the Wide Dynamic Execution Technology, the core is able to simultaneously execute up to four instructions.
The integrated Enhanced Speedstep is able to downclock the core dynamically to save power (in idle mode).
Intel Core 2 Duo SP9300
► remove from comparisonThe Core 2 Duo SP9300 is a power efficient (25W TDP) dual core CPU for laptops. Compared to other Core 2 Duo with 2.26 GHz, the SP9300 features the full 6 MB level 2 cache of the Penryn core. Usually 3MB are enabled for 25 W CPUs at this clock range (e.g. P8400). Therefore, the performance is a bit better than similar clocked C2D CPUs.
