Ive seen a few that struggle mightily to get over ~4.2 with Phanteks or Noctuas without getting up into the 90c range. The chips seem to have a wide window of quality. HW-Bot averages are a really rough thing to go off of too. Especially without looking at how broad the average peak is in the statistics.

motherboard can also play a huge role in where you get to.

I would go with the ryzen just for the upgrade path at the price point being given.

i would skip the 1600 and go straight for a 1700 though, the resell value of 6C/12T CPUs would sharply decline as AMD releases more cheap 8C/16T CPUs.

I've seen many people that can't even reach 4 GHz on Ryzen. I'm talking rock solid here. Not bench stable like in most reviews.

How were both systems OCed? What voltages did you change and how? Not saying you don't know, I just am aware that the ease of OCing multiplier unlocked chips has lead to a lot of people not realizing extra ways to get a few more Mhz out of a chip or some extra performance. (eg. I can get my 3570k to be mostly stable at 4.8Ghz without delidding/custom TIM/anything other than an NH-D14 and a cheap ASRock board through adjusting PLL voltages among other things, even if it means my 24/7 OC is the same and when I had a C2D I gained an extra 200Mhz on my stable 24/7 OC from mucking around with the PLL and NB voltages to increase FSB stability.)

Also, it's a new architecture with documented immaturity in UEFI and other low level software. It took a couple of years for CPU/NB overclocking with Phenom II to become a well known way to get a lot of extra performance easily, and a 800Mhz CPU/NB OC was roughly equal to a base CPU OC of 600Mhz iirc so it wasn't a small performance increase for the cost of some extra power consumption and time spent tweaking.

So be it. Not the point, but OK. Seeing the R5 Owner topic on this forum, we have 1 dude on 8 who made it to 4ghz. Platform still is new, so it should be easier with time.

The point was, 700 or 800 mhz over stock, is still a nice gain, and should not be qualified by the illogical expression "horrible overclocking".

To add more information on the question,

R5 1600 just hit 195€ (with expedition cost) in France.

R7 1700X in the same country was at its lowest, 350€.

Mainly using a chip for gaming and multi tasking, I'd personnally be more inclined to buy the 6 cores, and keeping the money left (in this example, ~150€) for Ryzen v2, rather than paying 150€ more (77% of 1600 cost) for 2 more cores (and 4 threads yes, useful for power softwares, but for games...)

EDIT: Error on my side, it's the 1700X and not the 1700. I edited my post.

1700 was at its lowest at 315€. It's still 115 to 120€ more, meaning 59% of R5 1600 price.

even at stock they perform adequately, overclocking them isn't as necessary as a few years back where stock clocks were at 2Ghz and a 400Mhz OC is easily 20% more performance.

the X variants of AMD's are always on the expensive side, its better to buy the non-X variants if you're on a budget, they can overclock nearly just as good as the X variants.
on a side note, 120€ more on a 1000€ rig is roughly 12% more in overall cost, the two extra cores on the other hand would give your entire rig more room for performance.


on another note, i sort of wish that they'd allow per-core overclocking, i'd truly want to overclock the cores based on load of each core.
this kind of feature would be beneficial if Ryzen didn't have such a low ceiling, where overclocking with less cores active nets a higher overclock.
