What Is the Size of a CPU in cm?
A bare desktop CPU die is typically about 1 cm by 1 cm, or roughly 100 mm². The package that holds the die is larger. A typical desktop processor package measures about 3.5 cm by 3.5 cm to 4.5 cm by 4.5 cm, depending on the socket. Mobile and embedded processors are smaller, and the chip itself is often a few millimetres across. Exact dimensions vary by manufacturer and model, so check the datasheet for the specific part.
CPU Size Compared with the Whole System
The processor is a small part of a computer's footprint. The table below shows how the processors in the Thinvent range relate to the systems that use them.
| Thinvent Product | Form Factor | Processor | Cores | Max Frequency | Cache |
|---|---|---|---|---|---|
| IPC5 (Intel Core i5-1240P) | Industrial PC | Intel Core i5-1240P | 12 | 4.4 GHz | 12 MB |
| Aero Mini PC (Intel Core i3-1215U) | Mini PC | Intel Core i3-1215U | 6 | 4.4 GHz | 10 MB |
| IPC3 (Intel Core i3-1215U) | Industrial PC | Intel Core i3-1215U | 6 | 4.4 GHz | 10 MB |
| Micro 5R | Thin Client | ARM Cortex A53 | 4 | 2.0 GHz | n/a |
| IPC5 (Intel Core i7-1255U) | Industrial PC | Intel Core i7-1255U | 10 | 4.7 GHz | 12 MB |
| Aero Mini PC (Intel Core 5 120U) | Mini PC | Intel Core 5 120U | 10 | 5.0 GHz | 12 MB |
| Treo Mini PC (Intel N5095A) | Mini PC | Intel N5095A | 4 | 2.9 GHz | 4 MB |
| Treo Mini PC (AMD Ryzen 5 7430U) | Mini PC | AMD Ryzen 5 7430U | 6 | 4.3 GHz | 16 MB |
Why the Package Size Matters
The package size sets how much room the cooling solution and the board need. Smaller packages, such as those in mini PCs and thin clients, allow compact cases. Larger packages, such as those in industrial PCs with 12 cores, need more heatsink area to keep the processor within its thermal limits. The Thinvent Micro 5R uses an ARM Cortex A53 processor, which suits a small, low-power design.
