Intel Core i9-9900K vs Intel Atom Z3775D

Last updated:
The Intel Core i9-9900K was introduced at its launch as a high-performance processor of the Coffee Lake S Refresh generation for enthusiasts and professional users.

In comparison, the Intel Atom Z3775D is based on the Bay Trail architecture and was specifically developed for energy-efficient, mobile end devices such as tablets.

The Intel Core i9-9900K is manufactured using the 14-nanometer process with eight cores and sixteen threads, while the Intel Atom Z3775D uses the 22-nanometer process and has four cores without multithreading. In benchmarks, the Intel Core i9-9900K achieves high single-core and multi-core performance, qualifying it for complex calculations.

For the Intel Atom Z3775D, no relevant benchmark values are available, which is why the computing power is to be classified far below that of the desktop model. In gaming scenarios, the Intel Core i9-9900K impresses with high clock speeds and a 16 MB L3 cache, supported by Intel UHD Graphics 630, PCIe 3.0, and a memory bandwidth of 43 GB/s.

The integrated Intel HD Graphics (Bay Trail GT1) of the Intel Atom Z3775D, on the other hand, is unsuitable for modern games. In terms of power consumption, the Intel Core i9-9900K requires strong cooling with a Thermal Design Power of 95 watts, while the Intel Atom Z3775D, with 11 GB/s memory bandwidth, is optimized for fanless designs with minimal energy requirements.

The price-performance ratio of the Intel Core i9-9900K is attractive for users looking for a stable platform for demanding tasks. The Intel Core i9-9900K is the clear recommendation for gaming and workstations, while the Intel Atom Z3775D is only suitable for the simplest mobile applications.
