What should I go with?

I'm thinking about upgrading myself, I currently have an 8700K. I'm on the fence about what platform to choose. Go with AM4 or AM5? Any suggestions?

If I do go with AM4, will I see a meaningful uplift in performance?

We did a revisit article on the 8700K a couple of years ago:


You can see that it's still a pretty potent CPU. Take Shadow of the Tomb Raider, as an example:

Looks pretty good, yes? Now do bear in mind, those tests were run with a GeForce RTX 2080 Ti. When we reviewed the Ryzen 5 5600X, the same game was used, but this time with an RTX 3090:

Now the 8700K was used in that review, but the Core i7-10700K was used in both articles. Notice how the 5600X is just as good as that CPU, but the 8700K was notably further behind? Now the GPU does have some impact here but the same GPU was used in the productivity tests:

So 1349 seconds for the 8700K and 1122 seconds for the 5600X. Doesn't sound particularly impressive but the 5600X has the same core/thread count as the 8700K and has a lower boost clock speed.

Given that AM5 platforms are mucho expensive at the moment, due to motherboard and DDR5 prices being sky-high, an AM4 platform would do very nicely. Paired with a 5800X3D and it would be very, very nice.

Do you have any benchmarks from productivity apps?

I've been hearing the same thing, AM5 is expensive to buy into. For me it would cost nearly $1200 to buy into it. It would involve the board, chip, memory, cooler, and PSU. Meanwhile, I could do an AM4 build for less than $700 and I wouldn't have to replace my PSU.

What's your budget and what components do you already have?

I'd like to keep it under $800. I already have my storage devices, I have decent enough DDR4 memory, I have a 650-Watt PSU, and an RTX 3060 GPU. It's just the board and chip that I want to replace.

But of course, the big question is... Would doing this kind of upgrade even be worth it? Will it give me the boost in performance that I'm looking for? I, myself, am looking for at the very least a 40% uplift in performance. Is that too much to ask for? If so, should I wait until next year?

Tough call tbh. If your system is doing what you want it to do then no need for upgrading imo. If you're looking to upgrade today then I think I'd do something like this with your budget.

Unfortunately, I'd have to get a new PSU if I were to go with that board since my PSU doesn't have that extra CPU 4-pin cable, only the 8-pin EPS along with, of course, the 24-pin ATX.

If I were to go with an AM4-based build, it doesn't look like it needs that extra 4-pin cable.
