Intel Core i3-N300
► remove from comparison![Intel i3-N300](fileadmin/_processed_/f/0/csm_intel_alder_lake_n_ablock_diagram_edf631640c.jpg)
The Intel Core i3-N305 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 8 efficient cores (E-cores, Gracemont architecture). The chip does not support HyperThreading and clocks with up to 3.8 GHz (single core, 3 GHz all core Turbo). 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 depends on the cooling and TDP settings and should be somewhere similar to the old Alder Lake Pentium 8500 (1 performance core, 4 efficiency cores, max. 4.4 GHz and 8 MB L3-cache). The multi-threaded performance should be quite good with the 8 cores but will suffer due to the low TDP. Single thread performance will suffer due to the missing P-cores and relatively low boost clock speeds.
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 offersall 32 EUs (Execution Units) operating at up to 1.25 GHz. In addition to the single channel memory, the gaming performance is very limited of the iGPU.
Power consumption
The i3 has a base power consumption of 7 W and is therefore even suited for fanless cooling. The CPU is built with a further improved 10nm SuperFin process at Intel (called Intel 7).
Intel Core i5-1038NG7

The Intel Core i5-1038NG7 or Core i5-1038G7 is a quad-core SoC for laptops and Ultrabooks based on the Ice-Lake-U generation that was announced in Mai 2020 in the refreshed MacBook Pro 13. It integrates four Sunnycove processor cores (8 threads thanks to HyperThreading) clocked at 2 (base) - 3.8 (single core Turbo) GHz. According to Intel the Sunnycove cores achieve 18% more IPCs (Instructions per Clock) and therefore the CPU performance should be similar to the higher clocked Whiskey-Lake and Coffee-Lake predecessors (e.g. Core i7-8559U, 2.7 - 4.5 GHz). The Core i5-1038G7 is the second fastest 28W model of the Ice Lake family after the Core i7-1068G7.
The biggest improvement for Ice-Lake is the integrated Gen 11 graphics card called Iris Plus Graphics. The Core i5-1035G7 integrates the biggest G7 variant with 64 CUs clocked at 300 - 1100? MHz. The Iris Plus G7 should be twice as fast as the predecessors and best the AMD Vega 10 GPU in current Ryzen APUs.
Other improvements for Ice Lake are the AI hardware acceleration and the partial integration of Thunderbolt and Wifi 6 in the chip. The integrated DDR4 memory controller supports modules with up to 3200 MHz (and LPDDDR4 3733).
The Core i5-1038G7 is produced in the new 10nm process at Intel that should offer a comparable performance to the 7nm process at TSMC. The TDP is specified at 28 Watts and therefore the CPU is best used in small multimedia laptops from 13-inch upwards (e.g. like a MacBook Pro 13).
Intel Processor N50

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).
