True enough, but at the voltages they are shooting for, I assume they are allowing for stock cooling, or not much more. It's a lot cheaper to buy better cooling and add a little voltage than it is for a $600+ 4.3 chip. I'm not bashing them, they have time and money invested and deserve to recoup. They sold out at that price; I just don't think 4.3 around the low 1.3x range will be a stretch for most of the 3800's. I hope i'm correct, but if that's a pipe dream on a 3700, that tells us something as well.

I've only seen one review online for the 3800 that compared it to the 3700; from someone that's legit, Gamers Nexus. However it's one of the worse videos they have ever put out IMO. They compared the chips at the same exact settings.... um, yeah? It's the same f-in chip at that point. They wasted 20 minutes of my life that I will never get back. Of course they came out dead on the same performance. Then they went on to not recommend the 3800's extra cost because of piss poor testing methodology. They did no overclock testing no over/under voltage, no per core cap speed test, useless review. The idea for 3800 would obviously be the higher base and even moreso the potential for higher top end.

3700X with a per CCX OC (4.4 all core is an instant reboot in cinebench ) 44x CCX 0 43x CCX 1 @ 1.35v (haven't tried tuning down further, after vdroop it's seeing as low as 1.31v but usually 1.325v - 1.337v)

Thank You, good info. Obviously too small a sample size to say "luck of the draw" or "binned", but that does show a bit of a difference between mine and yours. Although most would not think 100Mhz is worth $70.

I appreciate your time.

No problem, did you try the per CCX method? You could likely get 45x and 44x

Regarding your 15cb point improvement at 4.4, try maybe 4.35. Steve at GN often talks about clock stretching, in that 4.4 might actually be slower than 4.35 due to clock stretching.
Overclocking for performance is trying to find the optimum point of performance with the available TDP and architecture.
That does not always mean its the highest frequency which i think is what you might be experiencing.

I suspect a 4.35 or 4.375 will beat the 4.4 run.
You sir, are a genius. 4.35 beats 4.4 by 17pt and much better jump of 46pt over 4.3. Who woulda' thunk.

I have not yet, I'm still tinkering (and Playing Forza Horizon) looking for the max 100% stable then I can tinker with CCX and do a solid comparison.

Is horizon 4 stable? Sometimes the game just crash to desktop with a 1700x @3.8ghz.

I just yesterday started to tinker a bit with the manual OC when I watched a video showing SiliconLottery selling a 3800x for $600+ that was 4.3 all core at 1.3V. I thought that did not seem unreasonable to achieve for such a high price. Tested it on mine, no problem, completely stable, much lower temps than auto everything. So, I went up a step, I never tried another voltage I went right to 1.32V 4.4 all cores. So far completely stable, best part 59C under load, I was hitting 69C on auto everything. I have not tried any higher yet, but I have plenty of voltage and thermal headroom.

I am curious if any 3700X people can do similar, not a pissing contest, I truly would like to know if we are paying for silicon or just a higher TDP ID and internal clock markers.
For about 1.3 V (I was on 1.275, stable in AIDA64 stress and OCCT and anything doing on my PC, but restarting my PC imediately starting test in Cinebench R20) my ryzen 3700x could achieve just 4.2 Ghz.
4.3 Ghz haven't tried yet, but I bet It would request about 1.35-1.38 V to get stable, but I wouldn't like the voltages and temperatures got.
The conclusion: Ryzen 3800x is better than Ryzen 3700x. If the difference of 100-200 mhz is worth the difference cost is up to you.

I was looking for 3800x to replace good working 2700x but couldn't get it in timely fashion so had to settle for 3700x.BIOS 5007 was at this time. With full boost PBO set to all maximums (X10 and 200MHz OC), only couple of cores go over 4.3GHz (typically 4.317) and the rest is well above 4.2GHz. Voltages (depending on benchmark) are in the high 1.3v range (1.372 typically).
I was able to OC all cores to 4.4GHz but at a cost of 1.425v and temps just above 70c. (typically 72 -76c) which i think made CB r20 scores few points bellow benchmark at 4.35GHz. I see cooling as being most important to boost and OC (providing VRM and whole MB are up to scratch of course)
First picture is at 4,35GHZ and second with PBO enabled to max.

Yes, completely. Unfortunately for hrs on end sometimes.
