How Many Cores Do 12700KF CPUs Have?
Intel's Core i7-12700KF CPUs have 8 Performance (P) cores and 4 Efficiency (E) cores for a total of 12 cores.
The P cores are comparable to previous generation cores. They support Hyper-Threading, which means they provide two threads each.
E cores are focused on adding additional threads in an energy-efficient manner. They take up much less room on the CPU and generate less heat. However, their smaller cache and minimal interconnect capabilities make them more appropriate for offloading background tasks.
The Intel Thread Director handles scheduling between the types of cores. Running a game will primarily use P cores. At the same time, the Intel Thread Director may offload operating system tasks and low priority periodic events to E cores.

below.
Which Operating Systems Can Make Optimal Use of the E Cores?
The Intel Thread Director is used to help operating systems determine onto which cores to schedule work.
At least Windows 11 or Linux kernel 5.18 are required to make optimal use of the Intel Thread Director.
Linux support for the Intel Thread Director is included in version 5.18 of the kernel. Some improvements have been backported to earlier releases. Ubuntu 22.04 users can get backported performance improvements in the 5.15.35 kernel.
How Many Threads Does the 12700KF Have?
Hyper-Threading is only available on Performance cores. One thread for each of the 4 Efficiency cores plus two threads for each of the 8 Performance cores results in a total of 20 threads.
At What Frequency Does the 12700KF Run?
Prior to Intel's 12th generation of processors, CPUs had a single base frequency and max turbo frequency. With Intel's 12th and 13th generation processors, the Efficiency and Performance cores use two individual sets of frequency values.
The 8 Performance cores have a 3.60 GHz base frequency and support a 4.90 GHz max turbo frequency.
The 4 Efficiency cores have a 2.70 GHz base frequency and support a 3.80 GHz max turbo frequency.
What Does the KF Suffix in 12700KF Mean?
| Processor Name Suffix | Meaning |
|---|---|
| K | "K" means it's an unlocked CPU. Unlocked CPUs have configurable frequencies and thus support overclocking. Your "motherboard" must support overclocking to overclock unlocked CPUs. Motherboards with Z-series chipsets typically support overclocking. Learn more about what each chipset supports in my article Which Chipsets Work With Intel's Core i7-12700KF CPU?. |
| F | "F" means it requires discrete graphics. In other words, it doesn't have integrated graphics (basically a GPU built into the processor), thus requiring a standalone graphics card. |
The 12700KF model name has an F suffix. F-suffixed CPUs do not contain integrated graphics, and a separate graphics card is required.
The 12700KF model name has a K suffix. K-suffixed CPUs can be overclocked with a compatible motherboard.
Motherboards with a Z-series chipset typically support overclocking. For example, motherboards with the Z690 or Z790 chipset usually support overclocking Intel's 12th and 13th Gen Core CPUs. Learn more about what each chipset supports in my article Which Chipsets Work With Intel's Core i7-12700KF CPU?.
CPU Cooling for the 12700KF
A CPU cooler's TDP (Thermal Design Power) rating indicates how much heat it can dissipate in watts. If the cooler can't keep your CPU cool enough, your CPU may throttle (slow down), and your cooler will constantly run at full speed.
Intel CPU specifications indicate this power dissipation number as "Processor Base Power" and "Maximum Turbo Power."
The Core i7-12700KF has a base TDP of 125 watts and a max turbo TDP of 190 watts.
A CPU cooler can still work with a lower TDP rating than the TDP of a CPU. However, the CPU will eventually throttle itself to a lower frequency to allow itself to cool.
The CPU may not achieve or maintain maximum turbo speeds without adequate cooling.

The distance between heatsink screw holes for the LGA 1700 socket increased to 78x78 mm from the 75x75 mm spacing typical of recent sockets. This new spacing means you'll need a new cooler/

Motherboard Requirements for Core i7-12700KF Processors
For Intel's 12th generation Core i7 12700KF processor, you'll need a motherboard with an LGA 1700 socket and a compatible 700-series or 600-series chipset. However, 600-series chipsets were designed for the 12th generations Core processors and may limit the capabilities of your system.
Motherboards for Intel processors are made with chipsets provided by Intel. Each chipset offers a unique set of capabilities. However, motherboards must explicitly support features and capabilities for you to use them. Verify that a motherboard supports the features and capabilities you desire.
The "K" in the model name 12700KF means it's an unlocked processor that supports overclocking. You will need a motherboard with overclocking support to overclock this CPU. Motherboards with the Z690 or Z790 chipsets typically support CPU overclocking. If you don't want to use the overclocking functionality at this time, you can use a motherboard with Intel's other 700-series or 600-series desktop chipsets (e.g., H770, B760, H670, B660, H610).
The W680 and Q670 chipsets are intended for workstation and business use cases; their availability in stand-alone motherboards is limited.

Our Recommended RAM
Before purchasing memory, review your motherboard specification to verify which speeds are supported. For example, if a DDR4 motherboard stated that it supports "DDR4 3400(O.C.) / 3333(O.C.) / 3300(O.C.) / 3200 / 3000," that would mean that it could support DDR4-3400, DDR4-3333, and DDR4-3300 with memory overclocking, and DDR4-3200 and DDR4-3000 at stock speeds. Motherboard specifications also indicate the maximum capacity per stick of RAM (DIMM) and across all slots.
