How Many Cores Do 13900F CPUs Have?

Section Link

Intel's Core i9-13900F CPUs have 8 Performance (P) cores and 16 Efficiency (E) cores for a total of 24 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.

Check out our Recommended Motherboards for the 13th Gen 13900F below.

Which Operating Systems Can Make Optimal Use of the E Cores?

Section Link

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 13900F Have?

Section Link

Hyper-Threading is only available on Performance cores. One thread for each of the 16 Efficiency cores plus two threads for each of the 8 Performance cores results in a total of 32 threads.

At What Frequency Does the 13900F Run?

Section Link

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 2.00 GHz base frequency and support a 5.20 GHz max turbo frequency.

The 16 Efficiency cores have a 1.50 GHz base frequency and support a 4.20 GHz max turbo frequency.

What Does the F Suffix in 13900F Mean?

Section Link
Processor Name SuffixMeaning
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 13900F model name has an F suffix. F-suffixed CPUs do not contain integrated graphics, and a separate graphics card is required.

The 13900F model name doesn't have a K suffix. Non-K CPUs can not be overclocked.

CPU Cooling for the 13900F

Section Link

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 i9-13900F has a base TDP of 65 watts and a max turbo TDP of 219 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/heatsink or upgrade kit that supports the new configuration.

Motherboard Requirements for Core i9-13900F Processors

Section Link

For Intel's 13th generation Core i9 13900F 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 lack of a "K" suffix in the model name 13900F means it doesn't support overclocking. Because of this, you may not need to use the top of the line Z690-based or Z790-based motherboards that typically support overclocking. Instead, 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.

To use 13th Gen Intel Core CPUs with the 600-series chipsets, you'll need an updated BIOS. You either need to purchase one with an updated BIOS, perform the update with a 12th Gen CPU installed, or use the USB BIOS Flashback feature (if available).

Products that ship with a compatible BIOS are typically marked as "Ready" for 13th Gen Intel processors.

Locked Intel CPUs may come with a stock CPU cooler. These CPU models do not have a "K" in the name. While stock coolers will prevent your CPU from overheating, your CPU will throttle its performance during games and other intensive tasks. Higher TDP coolers will keep your CPU at turbo speeds for longer durations. Stock coolers are often quite loud at their maximum speed.

The LGA 1700 socket will require a CPU cooler that supports the new socket size. Some manufacturers are releasing upgrade kits for LGA 1200 heatsinks to support the new size.

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.
