Question Affordable 8-core

[IlanW22]

Hey, so I am building a pc with my girlfriend so that she can also game, but whilst trying to get the best bang for the buck CPU, I found the Ryzen 7 8700f for 175€ new, which is cheaper than even the R5 7600. It seems to be built on a newer process and to overall be faster, but I also saw that it has a total of 20 pcie lanes, of which the internet assures me that 16 would go to the GPU regardless. It also only supports pcie 4.0 although I don't know whether that's a problem, and it has 16mb of L3 cache as opposed to 32 on the 7600. It has 2 more cores though and looks like a good deal regardless. What do you guys think?

The Ryzen 8700f I think is effectively an apu with the onboard graphics disabled. I would suggest looking at the Ryzen 7 7700x or 9700x. Though if you have access to it, and wanted to go 6 core, there is the 7600x3d. Though I know that's only in certain areas. Could also look at the 7800x3d or if you can it, the newer 9800x3d.

Yeah but the 8700f is 175€ and my alternatives, the Ryzen 7 7700, Ryzen 5 7600 and Ryzen 5 9600x are 240 and 185 and 235 euros respectively, all of the options you mentioned are way more expensive and do not offer a substantial upgrade. We're building a 1440p rig, which will probably house a 7800xt class card. This means that an upgrade to any other CPUs than the ones I mentioned would provide diminishing and negligible returns. What i really wanna know is whether or not the Ryzen 7 8700f is capable of performing to the level of the 7600 in gaming or at least reasonably close to it, given that I'd like to give her the extra 2 cores. Its just the 20 pcie lanes im not sure about.

You lose PCI-E lanes for dedicated graphics cards, with the APU family of chips.

Although both the Ryzen 7000 desktop series and the Ryzen 8000G share the same AM5 platform, the way the I/O is configured between the families is different. For the Ryzen 7000 series, the chips have a total of 28 x PCIe 5.0 lanes. Of those, 24 x PCIe 5.0 are usable due to the DMI link between the CPU and the chipset using x4 of these. The Ryzen 8000G series is different in that they omit PCIe Gen 5 lanes and instead opt for PCIe 4.0 lanes, with the Phoenix (8700G/8600G) coming with 20 x PCIe 4.0 lanes, of which x16 are usable between graphics and M.2 storage. This means the Ryzen 7 8700G has a PCIe 4.0 x8 link for a graphics card (not x16), with 8 x PCIe 4.0 lanes for two PCIe 4.0 x4 M.2 SSDs.

So then that's

Oh if that's how that works then I'll stay away from that XD, thanks.
