Intel Core i3-8130U vs AMD Ryzen 7 1800X

Intel Core i3-8130U

The Intel Core i3-8130U is a power efficient dual-core SoC for notebooks and Ultrabooks (most likely) based on the Kaby Lake Refresh generation (and not Coffee Lake). It was announced in February 2018. Compared to its direct predecessor, the Core i3-7130U, the 8130U offers Turbo Boost for an increased single thread performance. The GPU is now named Intel UHD Graphics 620 but otherwise identical to the Intel HD Graphics 620. The integrated memory controller supports DDR4-2400 / LPDDR3-2133 and dual channel memory.

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

Clocked at 2.2 to 3.4 GHz, the Core i3-8130U offers a much better single core performance than the Core i3-7130U (2.7 GHz, no Turbo). Therefore, the overall performance should be comparable to the older Core i5-7260U (also 2.2 - 3.4 GHz). The Core i5-8250U offers four processor cores and therefore offers a much better multi-threaded performance.

Graphics

The integrated Intel UHD Graphics 620 (Intel Gen 9.5) is untouched from the 8th Gen Kaby Lake chips. In the Core i3-8130U it is rather low clocked with 1 GHz compared to the 1.1 GHz in Core i7 models. With fast dual-channel memory it can reach the performance of a dedicated GeForce 920M.

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 most likely manufactured in an improved 14nm process with FinFET transistors (14nm+), the same as the 7th Gen Kaby Lake processors. Intel still specifies the TDP with 15 Watts, which is typical for ULV chips. According to Intel it can be configured to 10 Watt at 800 MHz (cTDP-down).

AMD Ryzen 7 1800X

The AMD Ryzen 7 1800X is a fast desktop processor with 8 cores and SMT (16 threads) that was introduced in early 2017. It is based on the new Zen architecture and it is the fastest model at the time of announcement.

The CPU cores clock from 3.6 base speed up to 4.1 GHz (XFR). The 2-core Turbo is specified at 4 GHz and using all 8 cores, the CPU can reach up to 3.7 GHz. Therefore, the CPU offers 200 MHz more than the Ryzen 7 1700X.

The performance in applications that can make use of all 8 cores is very competitive to high end Intel CPUs at a very good price point. However, non optimized apps like many games can't make full use of the new architecture.
