Intel Atom x7405C

The Intel Atom x7405C is a 4-core (4-thread) processor built for the mobile CPU market. It launched in Q2 2024 with a suggested retail price of $57. It is part of Intel's Atom lineup, which is based on the Gracemont microarchitecture. The x7405C is compatible with Intel BGA 1264 motherboards and is fabricated on Intel's 10 nm manufacturing process.

Memory and Cache

The Atom x7405C supports DDR4-3200, DDR5 memory and features a single-channel memory controller, allowing it to utilize 1 memory modules simultaneously. In terms of cache, the Atom x7405C has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 96 KB in size, providing rapid access to crucial instructions. Its L2 cache, at 2 MB, is larger but slower than the L1. Its L3 cache, a shared resource among the CPU's cores, has a capacity of 6 MB.

Cores and Clock Speeds

The Atom x7405C features 4 total cores which can process 4 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The base clock speed of the CPU is 1700.0 MHz, and it can boost up to 3.4 GHz under heavy workloads. Higher clock speeds result in better performance for the same microarchitecture. The multiplier is locked, making it incapable of overclocking for pushing performance further.

Integrated Graphics

The Atom x7405C does not include an integrated graphics solution. A dedicated graphics card will be required if you require a monitor with your computer.
