Intel Core 2 Duo SP9400 vs Intel Pentium Silver N6005 vs Intel Core 2 Duo P8700

Intel Core 2 Duo SP9400

The 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.

Intel Pentium Silver N6005

The Intel Pentium Silver N6005 is a quad-core SoC of the Jasper Lake series that is primarily intended for inexpensive and small desktop and was announced in early 2021. The four Tremont CPU cores clock between 2 and 3.3 GHz (single core Burst) and offer no HyperThreading (SMT). The N6005 uses 1.5 MB L2 and 4 MB L3 cache. The chip is manufactured in 10nm at Intel (most likely in the same process as Ice Lake).

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 quad-core CPU block, the SoC integrates a 32 EU Intel UHD Graphics GPU clocked from 450 - 900 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 N6005 in our database is in the same league as the Core i3-1110G4, as far as multi-thread benchmark scores are concerned. This is enough to enjoy Web browsing and watch videos online without noticeable slowdowns, as of mid 2023 - which is what most consumers want.

Thanks to its decent cooling solution and a long-term CPU power limit of 15 W, the Intel NUC11ATKPE is among the fastest systems built around the N6005 that we know of. It can be about 50% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.

Power Consumption

Similar to the predecessor, Intel specifies the TDP with 10 Watts (versus the 6 W of the mobile N6000). The chip can therefore be cooled passively in theory, but SKUs with fans are possible as well.

Intel Core 2 Duo P8700

The Intel Core 2 Duo P8700 is a mid-range dual core processor for laptops. It features 2.53 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). Technically, the P8700 is a slower clocked P8800 CPU.

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 P8700 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).
