Intel Core i5-7300U vs Intel Core i5-1038NG7

Intel Core i5-7300U

The Intel Core i5-7300U is a fast dual-core processor for notebooks based on the Kaby Lake architecture and was announced in January 2017. It integrates 2 CPU cores with Hyper-Threading support clocked at 2.6 - 3.5 GHz (2 core Turbo also 3.5 GHz). Besides two cores, the processor is also equipped with the HD Graphics 620 GPU as well as a dual-channel memory controller (DDR3L-1600/DDR4-2400). It is manufactured in a 14nm process with FinFET transistors.

Architecture

Intel basically uses the same micro architecture compared to Skylake, so the per-MHz performance does not differ. The manufacturer only reworked the Speed Shift technology for faster dynamic adjustments of voltages and clocks, and the improved 14nm process allows much higher frequencies combined with better efficiency than before.

Performance

With 2.5 to 3.5 GHz, the Core i5-7300U clocks significantly higher than the old Core i5-7200U (2.5 - 3.1) and Core i5-6200U (2.3 - 2.8 GHz). Thanks to the fast Turbo frequency, the performance should be slightly below to the Core i7-7500U (2.7 - 3.5 GHz, but 4 MB L3 cache). Therfore, the performance is sufficient for demanding tasks.

Graphics

The integrated Intel HD Graphics 620 has 24 Execution Units (similar to previous HD Graphics 520) running at 300 - 1100 MHz. The performance depends a lot on the memory configuration; it should be comparable to a dedicated Nvidia GeForce 920M in combination with fast DDR4-2133 dual-channel memory.

Contrary to Skylake, Kaby Lake now supports hardware decoding for H.265/HEVC Main 10 with a 10-bit color depth as well as Google's VP9 codec. The dual-core Kaby Lake processors, which were announced in January, should also support HDCP 2.2.

Power Consumption

The chip is manufactured in an improved 14nm process with FinFET transistors, which improves the efficiency even further. Intel still specifies the TDP with 15 Watts, but it can also be reduced to 7.5 Watts by the notebook manufacturers (cTDP down). This will obviously affect the performance, because the Turbo Boost cannot be maintained for longer periods.

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).
