Intel Core 2 Duo P8400 vs Intel Celeron N4505 vs Intel Core 2 Duo SP9400
Intel Core 2 Duo P8400
► remove from comparison
The Intel Core 2 Duo P8400 is a dual core processor for laptops. It features 2.26 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).
The performance of the P8400 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 P8400 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).
The Core 2 Duo P8400 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 Celeron N4505
► remove from comparison
The Intel Celeron N4505 is a dual-core SoC of the Jasper Lake series that is primarily intended for inexpensive and small desktops and was announced in early 2021. The two Tremont CPU cores clock between 2 and 2.9 GHz (single core Burst) and offer no HyperThreading (SMT). The N4505 uses 1.5 MB L2 and 4 MB L3 cache. The chip is built with Intel's first-gen 10 nm process, just like Ice Lake family processors.
CPU Architecture
The processor architecture is called Tremont and a complete redesign compared to the old Golmont Plus cores in the predecessor. According to Intel, the single thread performance of a core could be improved by 30% on average (10 - 80% in all tests of SPECint and SPECfp).
Features
In addition to the dual-core CPU block, the SoC integrates a 16 EU Intel UHD Graphics GPU clocked from 450 - 750 MHz and a LPDDR4(x) dual channel memory controller (up to 16 GB and 2933 MHz). The chip now also partly integrates Wi-Fi 6 (Gig+), 8 PCIe 3.0 lanes, 14 USB 2.0/ 3.2 ports and two SATA 6.0 ports. The package got bigger and measures 35 x 24 mm (compared to 25 x 24 mm for the N5030 e.g.). The SoC is directly soldered to the mainboard (BGA) and can't be easily replaced.
Performance
The average N4505 in our database is just as fast as AMD's dual-core Athlon Silver 3050e and Intel's previous-gen Celeron N4100, as far as multi-thread benchmark scores are concerned. In other words, the Celeron is good for basic day-to-day activities but not much more than that, as of mid 2022.
Power consumption
This Celeron series SoC has a default TDP, also known as the long-term Power Limit, of 10 W, which is low enough to allow for passively cooled designs.
The N4505 is manufactured on the first-gen or the second-gen (no exact data available) 10 nm Intel process making for average, as of late 2022, energy efficiency.
Intel Core 2 Duo SP9400
► remove from comparisonThe Intel Core 2 Duo SP9400 is a laptop CPU with the full 6MB level 2 cache at 2.4 GHz and a TDP of only 25 Watt.
