Intel Core 2 Duo SP9300 vs Intel Core i5-430M
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.
Intel Core i5-430M
► remove from comparisonThe Intel Core i5-430M is a fast middle class dual core CPU for laptops and clocks (due to the Turbo Mode) from 2.26 to 2.53 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 430M only has 3 MB Level 3 Cache, missing VT-d, Trusted Execution, and AES features and a lower clock speed.
A feature of the new Core i5-430M is the integrated graphics card (called Intel HD Graphics) 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.
Due to the integrated memory controller, the HyperThreading and Turbo Boost, the Core i5-430M is faster than a similar clocked Core 2 Duo in all (us known) applications and benchmarks. In fact, the 430M even came close to a fast Core 2 Duo T9600 (2.8 GHz) in some benchmarks (e.g. Cinebench 10 Multi Threaded). This means the 430M is a fast middle class - performance CPU and much faster than the top AMD model, the Turion II Ultra M660 (at the time of announcement).
The 32nm cpu cores of the Westmere generation can also process some new instructions to accelerate AES encryptions. Still, these functions are deactivated on the Core i5-430M leading to some performance drawbacks in modern applications that support AES encoding using the new instructions (e.g. the Communications Suite test in the PCMark Vantage boosts up to 70% using AES in the faster Core i5-520M).
The integrated Intel Graphics Media Accelerator HD (GMA HD) graphics card is between 500-766 MHz (Turbo Boost) and is 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). The Turbo Boost can overclock the Intel HD Graphics up to 733 MHz when the cores are not fully used.
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).
