Which processor do I have?
Your computer will tell you its processor in a couple of clicks, and the chip itself carries the name too. What matters when you sell is the full model, down to the letters at the end — so here is where to find it and how to read it.
On Windows
- Settings → System → About. The Processor line gives the full name, such as “Intel(R) Core(TM) i7-13700K” or “AMD Ryzen 7 7800X3D 8-Core Processor”.
- Task Manager → Performance → CPU. The name is at the top right, with the core count and speed below.
- CPU-Z, a free utility, shows the name, the socket (“Package”), the core count and the stepping.
On macOS and Linux
On an Intel Mac, the Apple menu’s About This Mac names the processor. On Linux, lscpu prints it on the “Model name” line.
On the chip itself
If the processor is already out of the computer, the model is printed on its metal lid. Intel chips show the model number and an S-Spec code such as “SRMB8”; AMD chips show the model name and a part number starting “100-”. The retail box carries the same model on its label. Don’t pull a working chip just to read it — the software routes above are safer.
Reading the model number
- Intel Core: in “Core i7-13700K”, i7 is the tier (i3, i5, i7 and i9 from lowest to highest), 13 is the generation, 700 is the model within it, and K is the suffix. A four-digit number such as i7-8700K is 8th generation. Core Ultra chips, from late 2024, drop the “i”: Core Ultra 7 265K.
- AMD Ryzen: in “Ryzen 7 7800X3D”, Ryzen 7 is the tier (3, 5, 7 and 9), the first digit of 7800 is the generation, and X3D is the suffix.
What the letters mean
The suffix changes what a chip is worth, so check it carefully:
- Intel K — unlocked for overclocking. F — no integrated graphics. KF — both. T — low power.
- AMD X — higher clocks. X3D — extra 3D V-Cache, the gaming chips. G — integrated graphics. XT — a later, faster refresh.
