# Intel Xeon E3-1220 v6 Server CPU: Intel Also called intel xeon e3-1220 v6, xeon e3-1220 v6, e3-1220v6, xeon-e3-1220-v6 Intel, Server CPU, Kaby Lake (Server) Intel Xeon E3 server processor on Kaby Lake (Server), with 4 cores and 4 threads and 8 MB L3 at 72 W TDP on a 14 nm process addressing up to 64 GB and no integrated graphics. ## What you need to know Intel Xeon E3-1220 v6 is a legacy server cpu. Intel Xeon E3-1220 v6 launched in 2017., It has 4 cores and 4 threads on Kaby Lake (Server), dropping into the FCLGA1151 socket. Treat the spec table as the facts. Age alone does not tell you to throw it out. - **Still good?**: Only if the workload is light **Product age**: 9 years old **Upgrade pressure**: Moderate Feex says This SKU has no picture of its own. If the machine has no discrete GPU, a black screen after install is expected, not a dead CPU. ## What this hardware means today Age and usefulness are not the same number. This page keeps them separate. - **Performance today**: **Average.** Average for the class when RAM, storage, and the GPU keep up. **Product age 9 years old**: **Legacy.** Launched 2017. Newer platforms exist. That does not make this chip unusable by itself. **Support status **: **Supported.** Current Windows and current applications still run on this class of CPU. Platform BIOS support depends on the motherboard or laptop vendor. **Upgrade pressure **: **Moderate.** Upgrade pressure comes from platform features and specific CPU-bound work, not from the chip being unusable. ## Where does it sit? Kaby Lake (Server) sits on Intel's recent Core timeline. Later desktop branding moved toward Core Ultra. 11th Gen 12th Gen 13th Gen 14th Gen Core Ultra ## Performance context These are qualitative readings, not a fake 8.7 out of 10. Workload still wins. ### Gaming: Poor fit Not the job. Use a desktop or workstation part if games are the point. ### Productivity: Average 4 cores cover office, browser, and compile work in this class. ### Multithreaded workloads: Average 4 threads. Heavy encodes still scale further on higher-core parts. ### General use: Good Everyday Windows use is not where most people notice this SKU first. ### Efficiency: Good Rated 72 W base power. That is a platform number, not a promise about your cooler. ## Should you upgrade? Probably not based on CPU performance alone. ### Upgrade makes more sense if - Your workload is strongly CPU limited - You need a newer platform for memory, I/O, or chipset features - You need substantially more multicore performance - You need newer connectivity that your current board cannot offer ### Upgrade makes less sense if - The GPU is the real bottleneck - Current applications are already responsive - The CPU rarely limits your workload ## Specifications Figures below follow the Feex Hardware Database record for this SKU. Fields without a recorded value are omitted. ### Processor Intel Xeon E3-1220 v6 is built on Kaby Lake (Server) using a 14 nm process. | Manufacturer | Intel | | --------------------- | --------------------------------- | | Family | Xeon E3 | | Architecture | Kaby Lake (Server) | | Codename | Kaby Lake | | Generation | Intel Xeon Processor E3 v6 Family | | Manufacturing process | 14 nm | | Transistors | 1,750 million | | Die size | 126 mm² | | Die count | 1 | | Segment | Server | ### Cores and threads Intel Xeon E3-1220 v6 has 4 cores and 4 threads. | Cores | 4 | | ------------------- | -- | | Threads | 4 | | Threads per core | 1 | | Hybrid architecture | No | ### Clock speeds Base clock is 3.0 GHz.

Check the motherboard CPU list and BIOS revision. | | Memory | DDR4, up to 64 GB | | Graphics | Requires a discrete GPU. This SKU has no iGPU. | A shared socket is not automatic compatibility. Boards often need a BIOS update before a newer chip in the same socket will post. Cooler clearance, VRM quality, and power limits matter as much as the socket name. Do not expect a display from the motherboard video ports. This SKU has no integrated graphics. ### No display after install This SKU has no integrated graphics. A machine with no discrete GPU will not show a picture. That is expected, not a dead CPU. ## Related These entities connect to this article. Type is shown on every link.
