Intel Core i5-460M vs Intel Core 2 Duo P8800 vs Intel Core i5-470UM
Intel Core i5-460M
► remove from comparison![Intel 460M](typo3temp/_processed_/5/6/csm_INTEL_CORE_i5_Rotate_Badge_01_7da36722cc.jpg)
The Intel Core i5-460M is a high end dual core CPU for laptops and clocks (due to the Turbo Mode) from 2.53 to 2.8 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 Core i5-540M, the 460M does not support AES, VT-d and Trusted Execution functions and features a slower Turbo Boost (2.8 versus 3.06 GHz).
A feature of the new Core i5-460M 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 i5-460M 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 i5-460M 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 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.
Intel Core 2 Duo P8800
► remove from comparison![Intel P8800](typo3temp/_processed_/0/3/csm_core2duo_logo_10_78f76b12cf.png)
The Intel Core 2 Duo P8800 is a dual core processor for laptops. It features 2.66 GHz and a shared level 2 cache of 3 MB. Due to the smaller cache (Core 2 Duo T-Models got usually 6 MB at this clock rate), the TDP is only 25 Watt (instead of the 35 Watt of the T-models).
Due to the relatively high clock speed, modern games (in 2009) should not be limited by the CPU speed (in conjunction with a middle class graphics card). High end gamers should choose a higher clocked Dual Core instead (when using a high end GPU).
The P8800 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 1200 MHz to save power (in idle mode).
The Core 2 Duo P8800 can be used in a Socket P socket with 479 pins: Socket P / Micro Flip-Chip Pin Grid Array (Micro-FCPGA) requires 479-pin surface mount Zero Insertion Force (ZIF) socket (mPGA479M socket) or Micro Flip-Chip Ball Grid Array (Micro-FCBGA) for surface mount (479-ball)
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).
