AMD Ryzen 7 2800H vs Intel Core i3-7020U vs AMD 3015e

AMD Ryzen 7 2800H

The AMD Ryzen 7 2800H is a mobile SoC that was announced late 2018. It is intended for mid-sized to big laptops and combines four Zen cores (8 threads) clocked at 3.3 (base) - 3.8 GHz (boost) with a Radeon RX Vega 11 Mobile graphics card with 11 CUs (704 Shaders). The integrated dual-channel memory controller supports up to DDR4-3200 memory.

Compared to the older Ryzen 7 2700U for slim and light laptops, the 2800H offers a higher TDP (45 Watt versus 15 Watt), higher clocked memory, a higher base clock (3.4 versus 2.2 GHz), and a faster integrated GPU.

Performance

While we have not tested a single system built around the 2800H as of August 2023, it's safe to expect the chip to be 10% to 15% faster than Ryzen 3 1200, as far as multi-thread performance is concerned.

Your mileage may vary depending on how high the CPU power limits are, and how competent the cooling solution of your system is.

Power consumption

This Ryzen 7 has a default TDP (also known as the long-term power limit) of 45 W, a value that laptop manufacturers are free to change to anything between 35 W and 54 W with clock speeds and performance changing correspondingly. All the values are rather high, making a high-performance cooling solution with two or three fans pretty much a necessity.

The CPU is built on an old, as of late 2022, 14 nm process for subpar energy efficiency.

Intel Core i3-7020U

The Intel Core i3-7020U is a dual-core processor of the Kaby Lake architecture. It offers two CPU cores clocked at 2.3 GHz (without Turbo Boost) and integrates HyperThreading to work with up to 4 threads at once. The architectural differences are rather small compared to the Skylake generation, therefore the performance per MHz should be very similar. The SoC includes a dual channel DDR4 memory controller and Intel HD Graphics 620 graphics card (clocked at 300 - 1000 MHz). It is manufactured in an improved 14nm FinFET process at Intel. Compare to the old i3-7100U, the newer i3-7020U is clocked 100 MHz lower (CPU cores) and therefore the current entry level model for the Core i3 line. The similar Pentium Gold 4415U offers less Cache (2 versus 3 MB) and a slower GPU.

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.

AMD 3015e

The AMD 3015e is a dual-core, quad-thread processor (APU) of the Pollock product family. Its cores run at 1.2 GHz to 2.3 GHz and it has a low 6 W TDP, making it a good option for use in passively cooled laptops and ultra-small mini-PCs of the more affordable flavour. The processor first saw the light of day in 2020; it has a built-in Vega 3 graphics adapter running at up to 600 MHz.

Architecture & Features

This chip makes use of the rather dated Zen architecture for comparatively poor performance-per-MHz values. It has 4 MB of L3 cache and several PCI-Express 3.0 lanes for connecting NVMe SSDs, discrete graphics cards and other devices; its RAM controller functions in single-channel mode and supports DDR4-1600 memory or slower. AMD 3015e is compatible with Windows 10, Windows 11, and many Linux distros as well. Please note this is not a user-replaceable CPU. It gets soldered permanently to the motherboard (FT5 socket interface).

Performance

While we have not tested a single system built around the 3015e as of August 2023, we have some performance data for the 3050e, a chip that is just slightly superior. Based on that, the 3015e is a low-end option competing with the likes of the Intel N4500 and the Intel 4415U that is good for basic tasks and applications only.

Graphics

The Vega 3 runs at an unusually low clock rate of 600 MHz, or less. It will let you connect several monitors in resolutions as high as UHD 2160p, and it will happily decode AVC, HEVC and VP9-encoded videos, too. The latest AV1 video codec is not supported; such a video will have to be software-decoded, with the limited CPU horsepower putting a hard limit on video resolution that can be played back without stuttering. Expect to see a lot of dropped frames when watching a 1080p30 video.

Gaming is possible to a very limited extent with this iGPU. Even if it's CS:GO or a similarly old game that you want to play, be prepared to set the settings to Low.

Power consumption

This little AMD processor has a low default TDP (also known as the long-term power limit) of 6 W, making it one of the better options for use in a passively cooled laptop, tablet, mini-PC.

The AMD 3015e is manufactured on a 14 nm process leading to poor, as of mid 2023, energy efficiency.
