Intel Core i7-3940XM vs Intel Processor N50 vs Intel Processor N95
Intel Core i7-3940XM
► remove from comparison
The Intel Core i7-3940XM is the fastest quad-core processor for laptops (at the time of introduction in September 2012) an successor of the i7-3920XM. Due to Hyperthreading, the four cores can handle up to eight threads in parallel leading to better utilization of the CPU. Each core offers a base speed of 3.0 GHz but can dynamically increase clock rates with Turbo Boost up to 3.7 GHz (for 4 active cores), 3.8 GHz (for 2 active cores) and 3.9 GHz (for 1 active core). Furthermore, the Extreme CPUs offer an unlocked multiplicator for easy overclocking.
Ivy Bridge is an enhanced die shrink of the Sandy Bridge architecture with improvements on both GPU and CPU performance. The CPUs are produced in 22nm (versus 32nm Sandy Bridge CPUs) and are the first to introduce 3D transistors for increased energy efficiency when compared to similarly clocked Sandy Bridge processors. Other new features are integrated PCI Express 3.0 and DDR3(L)-1600 support.
The performance of the Core i7-3940XM should be slightly above a similarly clocked Sandy Bridge processor due to slight architectural improvements. Because of the higher clock speed, the former champion Core i7-3920XM should be outperformed by about 3%.
The integrated Intel HD Graphics 4000 offers 16 Execution Units (EUs) clocked at 650 MHz up to 1350 MHz with Turbo Boost, making it the fastest variant.
The XM CPUs are rated at a TDP of 55 Watts including graphics card and memory controller and therefore 10 Watt higher than the other quad-core models. Therefore, the CPU is well-suited for laptops 17-inches or greater.
Intel Processor N50
► remove from comparison
The Intel Processor N50 is an entry-level mobile CPU for thin and light laptops from the Alder Lake-N series. It was announced in early 2023 and offers no performance cores and 2 of the 8 efficient cores (E-cores, Gracemont architecture). The chip does not support HyperThreading and clocks with up to 3.4 GHz. The performance of the E-cores should be similar to old Skylake cores (compare to the Core i7-6700HQ). All cores can use up to 6 MB L3-cache.
Performance
The performance is clearly lower than the Processor N100 (4 cores, 3.4 GHz) due to the reduced core count. The single thread performance however, should be similar. Compared to older processors, the N50 should be comparable to dual core Skylake based CPUs like the Intel Core m3-8100Y (2x 3.4 GHz, 5W).Features
The Alder Lake-N chips only support single channel memory with up to DDR5-4800, DDR4-3200 or LPDDR5-4800. The chip also supports Quick Sync and AV1 decoding (most likely same engine as in Alder Lake). Furthermore, Wi-Fi 6E and Bluetooth 5.2 are partly integrated (but no Thunderbolt). External chips can be connected via PCIe Gen3 x9 (via the PCH).
The integrated graphics adapter is based on the Xe-architecture and offers only 16 of the 32 EUs (Execution Units) operating at only up to 750 MHz. Due to the single channel memory, low clock speeds, and low shader count, the gaming performance of the iGPU is very limited.
Power consumption
The N50 has a base power consumption of only 6 W and is therefore suited for fanless cooling. The CPU is built with a further improved 10nm SuperFin process at Intel (called Intel 7).
Intel Processor N95
► remove from comparisonThe Intel Processor N95 (sometimes also called Celeron N95 or Pentium N95) is an entry-level mobile CPU for thin and light laptops from the Alder Lake-N series. It was announced in early 2023 and offers no performance cores and 4 of the 8 efficient cores (E-cores, Gracemont architecture). The chip does not support HyperThreading and clocks with up to 3.4 GHz. The performance of the E-cores should be similar to old Skylake cores (compare to the Core i7-6700HQ). All cores can use up to 6 MB L3-cache. Compared to the similar Processor N100, the N95 offers a slightly higher TDP and therefore maybe a slightly improved sustained performance.
Performance
The average N95 in our database is in the same league as the Pentium 7505 and the Core i3-1115G4, as far as multi-thread benchmark scores are concerned. That's not a great result, to put it mildly.
Your mileage may vary depending on how high the CPU power limits are and how competent the cooling solution of your system is.
Features
The Alder Lake-N chips only support single channel memory with up to DDR5-4800, DDR4-3200 or LPDDR5-4800. The chip also supports Quick Sync and AV1 decoding (most likely same engine as in Alder Lake). Furthermore, Wi-Fi 6E and Bluetooth 5.2 are partly integrated (but no Thunderbolt). External chips can be connected via PCIe Gen3 x9 (via the PCH).
The integrated graphics adapter is based on the Xe-architecture and offers only 16 of the 32 EUs (Execution Units) operating at only 1200 MHz. Due to the single channel memory, low clock speeds, and low shader count, the gaming performance of the iGPU is very limited.
Power consumption
The N95 has a base power consumption of 12 W (compared to the 6 W of the N100) and is therefore well suited for thin and light systems. The CPU is built with a further improved 10nm SuperFin process at Intel (called Intel 7).
