Full description and specifications

The cheapest ticket onto AM5 — DDR5 and a socket with years of upgrades still ahead of it.

Quick Specs

  • 6 cores / 12 threads, 4.2GHz base, up to 4.7GHz boost
  • 22MB total cache (6MB L2 + 16MB L3)
  • 65W TDP, AM5 socket, DDR5 dual channel up to 256GB
  • TSMC 4nm process
  • Unlocked multiplier

Buying the platform, not just the chip

The 8400F is the entry point to AM5, and that matters more than its raw speed. A B650 board and DDR5 bought today will take a Ryzen 7 9800X3D or whatever AMD ships next — you replace one part, not three. Meanwhile the 8400F itself is no slouch: a 4.2GHz base is unusually high for the money, six Zen 4 cores handle modern games without stutter, and 65W keeps it cool on a basic tower cooler.

Know what the "F" and the cache mean

"F" means no integrated graphics, so a discrete card is mandatory — there's no display output without one. And like the rest of the 8000 series it carries 16MB of L3 and runs PCIe 4.0 rather than the 32MB and PCIe 5.0 of the Ryzen 5 7600 and 9600. In practice that costs a handful of frames, not a tier of performance. If you want the extra cache and PCIe 5.0, the 7600 sits just above it and is worth comparing on price.

FEATURES:

  • Entry onto AM5 with a long upgrade runway
  • High 4.2GHz base clock for the class
  • DDR5 support up to 256GB
  • 65W TDP — modest cooling and PSU requirements
  • Unlocked for overclocking

Questions

Before you buy

Which motherboards will this CPU fit?
It uses the AM5 socket, so it needs a motherboard with a matching socket. Sockets are not cross-compatible - a chip will not physically fit a board built for a different one. Every motherboard we list shows its socket on the Specifications tab, and it is worth checking the board maker’s support list for a BIOS update if the board is from an earlier generation than the chip.
How many cores and threads does it have?
6 cores and 12 threads. Cores do the work; threads are the number of jobs the chip can keep in flight at once. Games lean on a handful of fast cores, while rendering, compiling and video export scale with the total count.
What sort of cooler does it need?
It is rated at 65W TDP, which is the heat a cooler has to carry away under sustained load. Match or beat that figure with the cooler you choose, and check the What’s in the box list above - some processors ship with a cooler, some do not. Our PC Builder only offers coolers that fit the socket you have picked.
Do I need a separate graphics card with it?
Yes. This processor has no integrated graphics, so you will need a graphics card in the machine for it to output any picture at all. Budget for one in the build rather than treating it as a later upgrade.
Is it in stock, and when will it ship?
Yes - this one is in stock. Order before 12:00 on a working day and it ships the same day; after that it goes out the next working day. We are open 09:00 to 16:30, Monday to Friday, so an order placed over a weekend or a public holiday ships on the next working day.
What does delivery cost, and how long does it take?
We deliver by courier anywhere in South Africa, and delivery is R180 on orders under R2 500 and free on orders of R2 500 or more. It takes 1-3 working days to Johannesburg, Pretoria, Cape Town, Durban and areas within 100km of them, and 2-4 working days to areas more than 100km from a major centre, counted from the day the order is dispatched. Need it sooner? Express delivery is 1-2 working days for R210, or R150 on orders of R2 500 or more - choose it at checkout. We do not ship outside South Africa.
Can I collect instead of having it delivered?
Yes. Collection is from 11 Voortrekker Avenue, Edenvale, Gauteng, by arrangement - message us first so we can have the order picked and waiting. We are open 09:00 to 16:30, Monday to Friday.
What warranty does it carry, and how do I claim?
The warranty period for this product is listed at the end of the Specifications section above. Claims go through us, not the manufacturer - contact us with your order number and a description of the fault and we will handle it from there. Separately from any warranty, the Consumer Protection Act gives you six months from delivery to return goods that are defective, unsafe or not fit for their intended purpose.
What if I change my mind?
You have 14 days from delivery to change your mind - longer than the seven days the Electronic Communications and Transactions Act requires. The item needs to be unused and in its original packaging, and we pay the return shipping. Refunds go back to the payment method you used, within 30 days of the return reaching us.
How can I pay?
Payments are processed by Stitch. At the last step of checkout you are taken to Stitch’s secure page to pay, and brought back here once it is done. Your card details are entered on Stitch’s secure, PCI-compliant page and never touch our systems.
