MagyarIntel Core 2 Duo SL9400 vs Intel Core i5-470UM vs Intel Core 2 Duo T9300
Intel Core 2 Duo SL9400
► remove from comparison
The Core 2 Duo SL9400 is a power saving low voltage CPU for thin and light laptops. It offers a good performance for the 1.86 GHz clock rate, as it features the full 6 MB level 2 cache of the used Penryn core.
Intel Core i5-470UM
► remove from comparisonThe Intel Core i5-470UM is a Ultra Low Voltage dual-core processor for small and light laptops. It is clocked with 1.3 - 1.8 GHz (if Turbo Boost is enabled). 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). AES, VT-d and Trusted Execution are deactivated for the 470UM, compared to the i7 UM CPUs.
The faster i5-560UM and i7-660UM are also clocked at 1.3 GHz but feature a higher TurboBoost frequency.
A feature of the Core i5-470UM 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 i5-470UM is faster than a similar clocked Core 2 Duo (1.3 GHz) in all (us known) applications and benchmarks. Still the Turbo Boost may not trigger very often (sometimes it is even not activated in the BIOS) and therefore the maximum of 1.8 GHz may not be important.
The integrated Intel Graphics Media Accelerator HD (GMA HD) graphics card is clocked between 166-500 MHz (Turbo Boost) and therefore the base speed is clearly below the non low voltage versions. The performance should still be faster than the old GMA 4500MHD.
The power consumption of 18 Watt TDP (max.) counts for the whole package and therefore it is clearly better than the 17 Watt TDP of the Core 2 Duo SL-series (CPU alone).
Intel Core 2 Duo T9300
► remove from comparison
The Intel Core 2 Duo T9300 was a upper middle class dual core CPU for laptops, at the time of introduction. It is similar to the Core 2 Duo T9400 but features a slower clocked front side bus.
Due to the relatively high clock speed and 6MB Level 2 cache, the T9300 offers enough performance for most demanding games (in 2009) and applications.
The T9300 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).
