[Comparative] Upgrade from i5 2500k to i3 8350k

[krampak]

As I mentioned in another topic a few days ago, I decided to retire my old 2500k to tinker a bit with the new generations. Since the budget was €400 (company gift), I went straight for an i3 8350k that some reviews left quite good. Keeping the 4 cores without HT of the i5 2500k is a change that should serve me to compare a Gen2 with a Gen8 with quite equal conditions.
I have done 4 tests (less than I would like) to be able to show you some numbers.

It should be noted that the biggest difference I have personally noticed will not be reflected in these captures (mea culpa) since it was while gaming where I noticed the most change, specifically in Player Unknown, where I couldn't play in Ultra without noticing that the game wasn't fluid at all, now I can do it perfectly (40-70fps on the RX580).

The results of the i5 2500k are at 4.2Ghz, an OC totally affordable for any 2500k, while those of the 8350k are at 4Ghz, 4.6Ghz and 4.9Ghz. I also make a small comparison of temperatures of the 8350k with and without the Delid that I practiced today, waiting to try again the top of OC with the H115i that stayed at 5.2Ghz 1.32V in the SuperPI.

i5 2500k 4.2Ghz
SuperPI 2M: 20.625s
wPrime32M: 7.744s
Linx 1024MB: 106.30GFlops
HL Bench: 33726 / 117805
Cinebench R15 CPU: 553cb

i3 8350k 4Ghz (-4.76% clock)
SuperPI 2M: 20.690s -0.31%
wPrime32M: 6.718s +13.24%
Linx 1024MB: 195.76GFlops +84.15%
HL Bench: 68478 / 238808 +107.71%
Cinebench R15 CPU: 670cb +21.15%

i3 8350k 4.6Ghz (+9.5% clock)
SuperPI 2M: 18.143s +12.03%
wPrime32M: 5.844s +24.53%
Linx 1024MB: 219.20GFlops +106.20%
HL Bench: 77866 / 268824 +128.19%
Cinebench R15 CPU: 761cb +37.61%

And finally at 4.9Ghz and 5Ghz, I don't put the percentages because it doesn't make much sense to compare with the i5 2500k at 4.2Ghz, I would compare it with the maximum stable OC of this, which was around 4.5Ghz but I didn't do the tests.

As you can see, in some tests at 4Ghz (lower frequency) it already reaches up to 107% more due to the use of new instructions (VI mode of the HL Bench not available for the 2500k), but in raw power in GFlops in the Linx it also increases by 84%, quite remarkable. In contrast, in a simple program like the SuperPI that doesn't use any of these instructions, they practically get the same results.

Temperatures pre delid 1.24V:
28ºC idle / 55-60ºC full

Post delid/relid 1.24V:
28ºC idle / 46-53ºC full

Interesting review to see how the topic has evolved over the past 6-7 years. It seems that AVX2 helps a lot but the 8350K has something more than the set since in test#4 (not prone to improvement with mode increase), the performance per MHz has doubled. Could the extra 2Mb of L3 cache have helped?

Good beast, yes.

Congratulations on the change. I already saw that you sold the components on Hard2mano. I will continue to maintain my 2600K, the previous FX8350 platform went to my nephew. And the truth is, for the little that I play and what I do with the computer, I think my platform still has life left in it.

It must be recognized that the new Intels look very good, it was time for some significant change; but let's see how the next generation of AMD comes out. After a few years of Intel re-releases, it seems that this is taking life again.

Taking advantage of the cool weather these days, I took the PC out to the terrace (old school xD) and got 5.5Ghz out of the little i3, a shame that the memories are mediocre and that I didn't want to spend too much time upgrading them.
At 1.45v it crashed so I went straight to 1.5v seeing that under load it still didn't exceed 60ºC. Maybe I could have tried 5.6 but I'm already satisfied xD

What you say about PUBG happened exactly the same to me when I switched from a 4790K to the Ryzen 2600, even though I didn't expect much change from one to the other, it has improved enormously, but more than in the maximum or average FPS, in the minimum, which with the 4790K gave me some curious dips and with the R5 2600 not a chance, now I'm above 140fps almost all the time.

Am I mistaken or was it a long time ago that you put or tried to put the computer in the fridge?... The goat pulls the mountain jajaja tremendous. That was many years ago, more than 10 I think but I don't remember exactly.

@amd125 Correct xD I've done a few like that. From taking the PC out to the balcony when it was freezing, to putting the whole PC (back in the day a Pentium II 333) inside the industrial freezer at the restaurant my parents had. Then I also put the RL's radiator inside the kitchen freezer and not much more xD then I got professional and bought the Mach II in hardlimit and later the Vapochill LS.

@rul3s exactly, what I noticed the most was the stability in the framerate, without any dips.
