Retailing for $449 USD – which will be £410 in the UK, AMD is certainly charging a pretty penny for the Ryzen 7 5800X3D.

8-core Ryzen 7 5800X is £310-320, 12-core Ryzen 9 5900X is £365-375, and 16-core Ryzen 9 5950X is £505. Worth noting is that the 12- and 16-core parts both have 64MB of L3 cache by virtue of their dual-CCD designs.

So, AMD’s new eight-core with 96MB of L3 cache could be priced just as close to the sixteen-core flagship as the original Ryzen 7 that it enhances.

Versus Intel, the £385 Core i7-12700K and £560 Core i9-12900K are the contenders. Of course, we’re ignoring the £750 Core i9-12900KS as it is a stupidly-priced part that shouldn’t be bought.

Today's comparison processors come in the form of:

• Alder Lake Core i9-12900K (8P+8E24T) and Core i7-12700K (8P+4E20T).
• Vermeer ‘Zen 3' Ryzen 9 5900X (12C24T) and Ryzen 7 5800X (8C16T).

Each processor is tested at its default out-of-the-box settings. For the Intel CPUs, unlimited turbo duration as set by the motherboard with XMP enabled is the operating mode. All-core load frequencies for the tested chips are as follows:

• Core i9-12900K = 4.9GHz on the P-cores.
• Core i7-12700K = 4.7GHz on the P-cores.
  
• Ryzen 7 5800X = around 4.56GHz.
• Ryzen 9 5900X = around 4.25GHz.
• Ryzen 7 5800X3D = around 4.4GHz.
