Intel Core i5-8500T vs Apple S6 vs Apple S9 SiP

Intel Core i5-8500T

The Intel Core i5-8500T is a desktop processor of the Coffee Lake generation. It offers 6 cores clocked at 2.1 - 3.5 GHz and is manufactured in the again improved 14nm process (14nm++). As a "T" model, te i5-8500T is rated with a low 35 Watt TDP and therefore sometimes even used in laptops.

Thanks to the additional 2 cores, the Coffee Lake 6-core CPUs can offer a performance uplift of up to 50% in multithreaded workloads compared to the Kaby Lake predecessors. 

Apple S6

The Apple S6 is a 64-Bit dual core processor for the Apple Watch Series 6 (40 and 44mm). It integrates a GPU, 32 GB flash memory, Bluetooth 5.0, 1 GB RAM, 802.11 b/g/n 2.4 and 5 GHz WiFi and satellite positioning (GPS, GLONASS, Galileo, QZSS). According to Apple the SiP has two CPU cores based on the Apple A13 and offers 20% more performance than the old Apple S5 in the Watch Series 5.

Apple S9 SiP

The Apple S9 SiP (System in a Package) is a 64-bit processor with two cores (Sawtooth Dual-Core) that is used in the Apple Watch Series 9. The two CPU cores are based on the same microarchitecture as in the Apple A15 SoC. The chip also includes a Neural Engine (with 4 cores) for AI tasks for the first time.

The S9 offers 64 GB internal memory, L1 GPS, GNSS, Galileo and BaeiDou, WLAN 4 (802.11n), Bluetooth 5.3), and LTE / UMTS (optional). The ultra-wideband chip Apple U1 is also integrated.

The chip is manufactured in the modern 4nm process at TSMC (N4P).
