Compared products

YOUR FIRST CHOICE

AMD Ryzen 7 8700F

AM5 tray processor 100-000001590 · discrete graphics required

AMD's official processor artwork associated with Ryzen 7 8700F on its exact manufacturer product page; the visible artwork identifies the family rather than a readable exact model number.
Exact model & source notes

An 8-core, 16-thread Zen 4 processor for AM5 with up to 5 GHz boost, 16 MB of L3 cache, a 65 W TDP and a Ryzen AI engine rated up to 16 TOPS. It has no integrated graphics, so a graphics card is required; this is the tray version, so check whether the seller includes a cooler.

Specifications checked 12 Sept 2026.

Amazon links open search results. Check the exact variant, current price and availability with the retailer.

WHICH SUITS YOU?

Different designs: Zen 4 vs Zen 5. Their published clocks are listed, but a higher clock across designs does not mean faster.

Choose the Ryzen 7 8700F for

  • Lower stated default TDP: 65 W vs 120 W

Choose the Ryzen 9 9900X3D for

  • More stated CPU cores: 12 vs 8
  • Higher stated thread count: 24 vs 16
  • Higher stated L3 cache: 128 MB vs 16 MB

How to read this comparison
  • Manufacturer facts for the exact models shown. Not a quality rating or a test result.
  • “Different” means the known values differ, not that one is better.
  • Missing or conflicting evidence is marked and never counts as a difference. Source chips hold each fact’s sources and conditions.

WHAT EACH CHOICE ASKS OF YOU

What it brings and what to check

AMD Ryzen 7 8700F

What it brings

  • 8 Zen 4 cores and 16 threads with up to 5 GHz boost and 16 MB of L3 cache, at a 65 W default TDP.
  • Unlocked for overclocking, with EXPO, PBO, Curve Optimizer and Ryzen Master, plus a Ryzen AI engine (NPU) that AMD supports with its NPU driver.

What to check

  • No integrated graphics, so you need a separate graphics card. As a tray processor it may not come with a cooler; check the listing.
  • PCIe 4.0 only (16 of 20 lanes usable), and memory is rated at DDR5-5200 with two sticks but only DDR5-3600 with four.
  • AMD quotes the AI engine at up to 16 TOPS without saying how it was measured, so the figure is hard to compare with other NPUs.
  • AMD's 8700F page doesn't state ECC memory support; check the motherboard and CPU listing if you need ECC.

AMD Ryzen 9 9900X3D

What it brings

  • 12 Zen 5 cores and 24 threads with up to 5.5 GHz boost and 128 MB of L3 cache using second-generation 3D V-Cache.
  • Unlocked for overclocking, with EXPO, Precision Boost Overdrive and Curve Optimizer, plus PCIe 5.0 (24 usable lanes) and ECC memory support on compatible motherboards.

What to check

  • No cooler in the box, and AMD recommends liquid cooling for best performance.
  • Needs an AM5 motherboard whose BIOS supports this processor, plus DDR5 memory; check the board's CPU-support list before buying.
  • Memory is rated at DDR5-5600 with two sticks but only DDR5-3600 with four.
  • AMD's pages disagree on maximum memory (256 GB on the product page, 192 GB in AMD's shop listing) and on the processor's native USB ports. If you plan to fit more than 192 GB, check the motherboard's memory support list, and go by the motherboard's own USB specification.
