I am a bit biased even though AMD have slashed prices by $100 I'm still not an AMD fan as I said above so if I consider 8 core CPUs I will stick with Intel and add Skylake X. Thanks to AMD for reducing Intel prices.
Amazon prices are:
i7-8700K $404 plus Asus Prime M/B Z370-A $194 = $598
i7-7820X $500 plus Asus Prime M/B X299-A $260 = $760
Ryzen 1900X $450 plus " " " X399-A $332 = $782
Ryzen 1800X $350 " " " X370-A $128 = $478
According to UserBenchmark the 1900X is only 3% faster than the 1800X. The i7-7820X is 15% faster than the 1900X and slightly cheaper with motherboard. The 1800X is 5% faster than the 1700X but only 1% when overclocked. In the video above the i7-8700K outperforms the 1700X by a clear margin due to 5Ghz clock speed and seems to offer good value and performance for 4K editing. Please correct me if I'm wrong.
I think it's just a matter of deciding how to evaluate options. To me it doesn't make complete sense to compare CPUs with an equal core count. I buy CPUs based on how they perform, and I don't care about how many cores they have with the exception of what performance that leads to. And if we then hypothetically say that the CPUs and platforms are on par, and only look at the cost of a CPU+motherboard, then the next question is how much you're willing to spend.
It basically makes as much sense to compare a $475 setup with a $600 setup, as it does a $780 setup with a $985 setup. Why? Because the price difference is the same fraction. And currently the price difference here in the US for Threadripper is close to 'proportional' between cores / price. So 50% more cores = 50% more money. $450 1900x means roughly $675 1920x (12cores). Add the motherboard and you're looking at about $1k. So that's another comparison you can make if money is no object. But at that point, you'll probably start looking at the highest end Intel CPUs as well.
So really what it boils down to is a) what features do you
need, and b) how much do you want to spend. If you need Thunderbolt then no AMD, unless you want to gamble and hope the Gigabyte Designare will provide it next year with an update. If you need a bunch of lanes then several Intel options are out of the question. And then once that's figured out just put a price cap on it and see what holds the most value.
The 8700 has a high value not because of its performance, but because of its price versus performance. I also object to the comparison in the video because if the selling point is "bang-for-buck" then I just don't see it at that price point. Surely a 1700, stock cooler and overclocked will be a better value?
