Intel 7800X or 8700K ?

[LilWhiteChris]

I can buy a 7800x for £300
or a 8700k for £387

Is 0.1 more Ghz really worth £87?
Am i missing something here because the 7800x seems way better value for money?

Tough call. The 7800X was released, then quickly replaced by the 8th gen, a response from AMDs Ryzen processors.
It uses the LGA 2066 socket, which the currently cheapest mobo is 190USD, so the mobo will cost more.

Honestly, Its the same processor, but supports Quad Channel RAM, if your into that kind of thing. The reason why the price is so low is they want to clear out that stock as fast as possible. I'd snag it, it'll be gone soon, and for that price, its a short-lived steal.

Just be advised that you'll need a heck of a cooler. That generation is infamous for heat.

The 7800x requires a more expensive x299 chipset motherboard. It provides a true 28 PCIe 3.0 lanes. While the 8700K only provides 16 (plus 24 shared via DMI).

For most gamers and other home users. There isn't an appreciable advantage to the extra real PCIe lanes.

The 24 shared lanes are shared over an interface with about a PCIe 3.0 x4 speed. Which is fine for most users. But could be overwhelmed in a workstation scenario with say USB 3.1 Gen2, 10 GbE and NVMe SSD all being accessed simultaneously. While a workstation user can have dual GPU utilizing x8/x8 lanes with 12 lanes remaining for all other peripherals and network connections.

The X299 motherboards can also support more RAM.

Since you can get such a better price on the 7800X for so much less. I would certainly take that over the 8700K. Just to have a higher end, more expandable X299 chipset motherboard. There isn't much difference in the OC limits. In this case the 7800x is a better buy.
