AMD Ryzen 3 3200U vs Intel Core i5-8257U

AMD Ryzen 3 3200U

The AMD Ryzen 3 3200U is a dual-core SoC designed for laptops that was announced in January 2019. The Ryzen features two Zen cores with support for the thread-doubling SMT tech, clocked at 2.6 GHz - 3.5 GHz. The built-in Radeon RX Vega 3 iGPU has 3 CUs (192 unified shaders) clocked at up to 1,200 MHz. The default TDP is 15 W which makes the Ryzen a good fit for thin mid-range laptops.

In comparison to the faster Ryzen 3000 CPUs, the 3200U is not using the newer Zen+ microarchitecture and is still manufactured in 14nm. Compared to the old Ryzen 3 2200U, the 3200U therefore only offers a 100 MHz higher clock speed.

The Ryzen 3 is compatible with single-channel or dual-channel DDR4-2400 RAM.

Performance

The average 3200U in our extensive database is anything but a performance monster, its multi-thread benchmark scores only just matching those of the Core i3-8130U and the Pentium N6000. While not as atrociously slow as most N-series and J-series Intel chips, this specific Ryzen is good enough for basic day-to-day activities only.

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 3 series chip has a default TDP, also known as the long-term power limit, of 15 W. Laptop makers are free to change that to anything between 12 W and 25 W; most will go for a higher value to extract more performance out of it. Either way, an active cooling solution will be needed to dissipate the heat.

The R3 3200U is built with a 14 nm manufacturing process for low, as of early 2023, energy efficiency.

Intel Core i5-8257U

The Intel Core i5-8257U is a quad-core SoC for notebooks based on the Coffee Lake architecture that was announced in the new entry level MacBook Pro 13 in mid 2019. Compared to its predecessor, the CPU is now a quad-core with Hyperthreading support for the execution of up to 8 threads simultaneously. The base frequency is only 1.4 GHz, but the Turbo goes all the way up to 3.9 GHz. It is also equipped with an Intel Iris Plus Graphics 645 GPU with 128 MB eDRAM, a dual-channel memory controller (DDR4) as well as VP9 and H.265 video decoding as well as encoding. The chip is still manufactured in a 14nm process with FinFET transistors.

Compared to faster Core i7-8557U model with eDRAM and 15 Watts, the i5-8257U only features 6 MB smart cache and the slowest clock of the Iris Plus GPU.

Architecture

Intel basically uses the same micro architecture compared to Kaby Lake, 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

Thanks to the relative high Turbo Boost clock, the single thread performance should be very good, but still behind the faster i7 model. The short burst all core performance is clearly better compared to the old dual core predecessors thanks to the additional cores. In sustained workloads, the performance is usually limited by the TDP and cooling. In these workloads the difference to the Core i7 should be also smaller.

Graphics

The integrated Intel Iris Plus 645 Graphics is the GT3e model of the Coffee Lake GPU (Intel Gen. 9.5). It has 48 Execution Units running at 300-1050 MHz and the performance is comparable to a GeForce 930M or 940MX thanks to fast eDRAM cache. However, there aren't any significant improvements compared to the old Iris Plus 650, so modern games can often not be played smoothly or only at the lowest or medium settings, respectively.

Contrary to Skylake, Kaby lake now also supports H.265/HEVC Main 10 with a 10-bit color depth as well as Google's VP9 codec. The dual-core Kaby Lake processors 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 specifies the TDP with 15 Watts and therefore suited for thin and light laptops.
