Wow thanks for this. I noticed the 13700k results are surprisingly lackluster. The highest speed memory kit there is 5600. I just got a 13700k with Hynix A-die (now clocked to 7200). I have an AIO arriving in the mail in a few days to replace my NH-D14. The 13700k has quite a bit of headroom when not thermally constrained.

I think that the 13700k and 13900k with the same turbo ratio should perform almost the same in gaming workloads. The only difference should be in the 36 MB of LL cache vs. 30 MB. It's a modest difference, but factorio is memory subsystem performance sensitive.

I'll add a benchmark to that page in a few days with a 5.8 GHz clocked 13700k to test the theory.




Update for posterity: The ALF II 280 actually performed the same as my NH-D14 in thermal stress testing. I ran y-cruncher for an all-core workload that reliably thermal throttled 100 C @ 220 W. The clock frequency is dependent on the voltage given, which has been a pain to tune. I don't think this chip can go beyond 5.6 GHz stable without adding so much voltage that it is actually lower performance in most workloads. 5.7 GHz can be made borderline for most workloads, 5.8 GHz is unstable, and 5.9 GHz does not boot. I know the adaptive selection voltage mode should be able to address this, but something about the BIOS is incorrect. These results refute my theory that the 13700k could match the 13900k and the 13900k is in fact well-binned.

That doesn't mean the 13700k can't match (or exceed) the out-of-box Factorio performance of the 13900k when given better memory, hence the score of 304 UPS.

Bonus: E-cores have thermal headroom at stock and can be stable at 4.5 GHz if given +0.1 V, but this cuts into the thermal headroom of the P-cores in all-core workloads and lowers the overall performance. Bumping to 4.3 GHz from 4.2 GHz with no voltage increase is stable.


A Noctua NH-D14 is considered "thermally constrained" for these 13th gen chips? Good lord.

I'm looking forward to your test results though as I'm considering building a new desktop around 13th gen.


Not sure about the performance of NH-D14 and 13700K, but my NH-D15 (upgraded from NH-U12A) is running OK for 13700k with Intel's PL1/PL2 settings, hovering around 60~70c during full load at 25c ambient temperature. Unlimited PL2 is a different story and can go up to 100c during full load. My previous NH-U12A build ran at about 2-4c higher temperature under load.

I've been experimenting with different settings and found that unlimited PL2 and undervolting the CPU by -150mV give the best temperature to performance at ~80c during full load. It has been running stable for few days, and I'm pretty happy with the result so far.


For stability testing I like y-cruncher. It teases out edge cases that many XMP profiles are unstable with. I'd take a slightly less efficient system that I am confident will not error.

Also, those numbers aren't far off the out-of-box behavior I had, but I like to tinker. I throttle with PL set to 190 but not at 180.


I'd avoid Intel entirely if heat/power efficiency matter to you at all. AMD has had acceptable performance with far better heat/power use across the board for a few years now.
