Your opinion on upgrading from an i7 2600K (lemmy.ml)

Hello everyone. I'm one of those rare sea birds that in 2023 still rides an i7 2600K OCd @ 4.8 GHz since launch day.

I've been poking and experimenting in and out of more recent computers but aside from the GPU upgrade, I haven't really decided to let my i7 2600K retire.

It's just that I can't feel the "fastness" in new builds, however I honestly didn't spend much time with a current gen high end machine.

Seeing as we are getting closer to yet another generation of AMD and Intel's, do you guys think it will be worth it?

My full specs are: i7 2600K @ 4.8 GHz Gskill 32 GB 2133 CL10 DDR3 ASRock Z77 Extreme 6 (I swapped an Asus one year after when Z77 was released) 750W Corsair PSU 2x 500GB Raid0 Samsung Evo 2x 500GB Raid0 Crucial MX500 AMD 6750 XT along with a QHD 27" 165 Hz (started with an HD5870, then TO 380 now RX 6850XT)

When you upgrade, it's going to be big. You'll need a new mobo and new RAM to go with that new CPU. Maybe get a faster SSD too since you're currently running SATA.

I was curious about the CPU, so I pulled some ratings from cpubenchmark.net

i7 2600K @ 3.40GHz: 5478 / 1742

i5 13600K @ 3.5 GHz: 38353 / 4176

Ryzen 7700X @ 4.5GHz: 36351 / 4258

If you plan to overclock any new CPU proportionally, then a CPU upgrade will give you an absolutely insane boost to multithreaded performance, and almost 2.5x the single-core performance. Honestly 2.5x doesn't seem like a lot for a 12-year jump but it's nothing to sneeze it either.

If you're not planning to overclock a new CPU like you did with your old one, and you're dealing with mostly single-threaded workloads, then the difference won't be so striking. Which is honestly surprising given how old that CPU is; it's been a bad decade for single-thread performance, for sure, but I was still expecting a bigger difference.

Personally, I upgraded recently from a Ryzen 1700 to a 7700X, and it's a huge bump for me. I forget exactly what the numbers were, but my framerate and performance in Civ6 skyrocketed. Generally PC usage is noticeably faster; nothing revolutionary but certainly noticeable in web browsing and stuff like that.

I actually downloaded the software and ran it in my windows 11 dev drive, and it seems overclocking the CPU is quite the impact, netting me over 2000 points extra! To be fair i don't know the reference speed at all, as i've had it overclocked since day one ! When i get a newer system i plan on overclocking, but from what i've been seeing overclocking a newer CPU doesn't net as much juice as these old boys can do! That single core performance uplift should probably impact php/javascript quite a lot for my daily work, i will compare it when i finally pull the upgrade trigger!

Nice! That's right in the range you'd expect given the overclock. 1742 / 3.4GHz * 4.8GHz = 2459, a bit above your result of 2336. And for multi, it's 5478 / 3.4 * 4.8 = 7734, a bit below your results.
