Intel Core i5-7300U vs Intel Celeron N3050 vs Intel Celeron N3160

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 Celeron N3050

The Intel Celeron N3050 is a low-end dual-core SoC for notebooks, which has been presented in April 2015. It is clocked at 1.6 - 2.16 GHz and part of the Braswell platform. Thanks to its new 14 nanometer low-power process (P1273) with tri-gate transistors, energy efficiency has been significantly improved compared to its predecessor Bay Trail (e.g. Celeron N2840). In addition to the CPU cores, the SoC offers a DirectX 11.2-capable GPU as well as a DDR3L Memory Controller (2x 64 bit, 25.6 GB/s).

Architecture

The processor cores are based on the Airmont architecture, which is basically a slightly modified shrink of the previous Silvermont core. While performance per clock has not been improved, the more efficient 14 nm process leads to a better utilization of the CPU Burst (alias Turbo Boost) and a therefore somewhat higher overall performance.

Performance

Compared to its predecessor Celeron N2815 (1.86 - 2.13 GHz), the N3050 offers an almost identical performance. Using Windows, the CPU is adequate for simple everyday tasks such as light Internet browsing or office applications, but not for complex software or modern games.

Graphics

The HD Graphics (Braswell) is based on the Intel Gen8 architecture, which supports DirectX 11.2 and is also found in the Broadwell series (e.g. HD Graphics 5300). With 12 EUs (Execution Units) and a clock speed of up to 600 MHz, the GPU is almost twice as fast as the HD Graphics (Bay Trail), but still not powerful enough to handle modern 3D games. The GPU also supports 4K/H.265 video acceleration.

Power Consumption

The entire SoC is rated at an TDP of 6 watts (SDP 4 watts). Thus, the chip can be cooled passively.

Intel Celeron N3160

The Intel Celeron N3160 is a quad-core SoC for entry-level notebooks, which has been announced in early 2016. It is clocked at 1.6 - 2.24 GHz (Burst) and part of the Braswell platform. It is manufactured in a modern 14-nm process (P1273) with FinFETs. In addition to the four CPU cores, the SoC offers a DirectX 11.2-capable GPU as well as a DDR3L Memory Controller (2x 64 bit, 25.6 GB/s). Compared to the predecessor Celeron N3150, the N3160 has a 160 MHz higher Burst clock.

Architecture

The processor cores are based on the Airmont architecture, which is basically a slightly modified shrink of the previous Silvermont core. While performance per clock has not been improved, the more efficient 14 nm process may lead to a better utilization of the CPU Burst (alias Turbo Boost) and therefore a somewhat higher performance in certain situations. The per-MHz performance is still much lower compared to the more expensive Core series (e. g. Broadwell).

Performance

With 4 CPU cores and a clock between 1.6-2.24 GHz, the technical specifications are similar to the previous Celeron N2930, so the processor performance is only slightly better. This means the processor is well-suited for everyday tasks (office, browsing) and even light multi-tasking should be no problem.

Graphics

The HD Graphics (Braswell) is based on the Intel Gen8 architecture, which supports DirectX 11.2 and is also found in the Broadwell series (e.g. HD Graphics 5300). With 12 EUs (Execution Units) and a clock speed of up to 640 MHz, however, the GPU performance is much lower. On average, the GPU is almost twice as fast as the HD Graphics (Bay Trail), so its a bit slower than the older HD Graphics 4000. Only older and simpler titles like Counter Strike: GO will run smoothly. The chip still includes an advanced video unit with support for 4K/H.265 video acceleration.

Power Consumption

The entire SoC is rated at an TDP of 6 watts (SDP 4 watts). Thus, the chip can usually be cooled passively.
