MagyarIntel Core i5-470UM vs Intel Core 2 Duo P7550 vs Intel Core 2 Duo T9400
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 P7550
► remove from comparisonThe Intel Core 2 Duo P7550 is a dual core processor for laptops. It features 2.26 GHz and a shared level 2 cache of 3 MB. It is an OEM CPU and similar to the Core 2 Duo P8400 (additional Trusted Execution Technology, and VT-x) and Core 2 Duo P7570.
The performance of the P7550 is on par with the fast Turion II Ultra with about 2.4 to 2.6 GHz. Modern demanding games like Supreme Commander may be limited by the CPU performance. High end gamers should choose a higher clocked Core 2 Duo (or Core i5 / i7).
The P7550 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 as low as 800 MHz to save power (in idle mode).
Intel Core 2 Duo T9400
► remove from comparison
The Intel Core 2 Duo T9400 was a uppder middle class dual core CPU for laptops, at the time of introduction. It is similar to the Core 2 Duo P9500 except for the higher TDP of 35 versus 25 Watt).
Due to the relatively high clock speed and 6MB Level 2 cache, the T9400 offers enough performance for most demanding games (in 2009) and applications.
The T9400 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).
