Someone offered a used 10600kf (cpu only) for $160. would this be a better path than AMD 3700x or 5600x (more money)?

I would need to get mobo and ram as well.

I mostly game at 1440p and just some video editing with premiere pro and bit of vray.

The i5-10600KF will typically outperform the 3700x in most tasks. The 5600x is unobtanium. Between the options presented it appears to be the best choice.


Assuming it is a good choice to upgrade at all?

Huh? 10600 is only 6 cores, 3700x is 8 cores, so in productivity it certainly will outperform the 10600. In gaming, the 10600 will probably have a slight edge in most cases. If you can get a 10600 for 160.00 and trust that it is working properly, seems like a good deal. You would need a Z series motherboard and a good cooler to fully take advantage of the KF though.

It is real close.

Those 4 extra threads help the Ryzen, but the Intel has about 10% speed per thread on the Ryzen. It is true that Ryzen has 25% more threads.

While apps that push more then 12 threads are increasingly common, it is pretty rare they scale those threads perfectly. Sync locks, spin locks, all that slows that scaling down a bit. In the case of an app actually pushing 16 vs 12, it is going to be real close. Real world, likely less then 10% difference.

And for all the rest of the Apps that use 13* threads or less, the Intel wins. I would argue my statement stands, the Intel will typically out perform the Ryzen in this comparison.


*even if the threads scale perfectly, the intel's per thread advantage gives it the equivalent of another thread

Actually it is the thread advantage is 16/12 = 33%, and AMD "hyperthreading" or whatever they call it is more efficient than intel's. So no way intel 6 core will beat Zen 2 8 core in multithreaded benchmarks. Gaming (in most cases) or lightly threaded benchmarks, of course, Intel will win. Perhaps I should have been more clear, but by "productivity" I meant heavily threaded uses like encoding, which I think is the generally accepted way of using the term.

Games about 7% faster at 1080P ultra vs 3700X (green bar is stock 10600K with DDR4-3200 memory - blue is power unlocked - red is with a 5.1Ghz OC) :

Productivity about 8% slower than 3700X (TPU has a very broad range of productivity including things like vmware, office, and the obligatory rendering / encoding benchmarks) :

More importantly here, can you get a 3700x for anywhere near $160? At least with LGA 1200 board you'll have a chance at Rocket Lake next this year. I've been helping people build out 10400 systems at that price point.

I think the 10600k is going to be fast at gaming and good enough at anything else to be an easy pick in a sub $200 price point.

I mean, you can have a board and a CPU for the price of a 5600x. And likely the same story for a 3700x.

While the 5600X is a better part, a 10600k for that price is the better deal really. For most users a solid mid-range and up CPU will last you quite a few years regardless of who made it.

I just finally received a pair of Ryzen 3500X CPUs that I had ordered on AliExpress around 1.5 months ago. Haven't tested them yet, but they look genuine. They were $125 USD ea.

update, Got the 10600kf with New MSI z490 Pro board.
Initial test shows easy OC @ 5.1ghz with 1.275v and 1avx.

Would I gain much from overclocking DDR4 with this cpu? I have Corsair vengeance RGB pro 8x2 gb set and its running fine at XMP 3200 16c. Says C-die Hynix , am I out of luck? Should I even bother?

There's gains to be had from pushing the ram. There are good RAM overclocking guides out. What are your temps like?

This is a sub- or side-topic -- the RAM. I'm just butting in for a minute, but would make this observation.

You can buy RAM spec'd to run at DDR 4000 and beyond. I use Trident Z "GTZ" DDR4-3200 14-14-14 sticks, when I could buy faster ones. Today's RAM has more than four basic latencies to tweak, but at the same time the XMP specifications are probably optimal. You might squeeze an extra sliver or two in speed under benchmark tests, but you could also shorten the life of the modules if the tighter latencies require higher voltage, and you wouldn't much notice the difference.

That being said, the command-rate, "CR", is the simplest tweak you can make, provided you're only using two sticks in the motherboard. You can set the default command rate to 1 instead of 2. I actually believe that I can tell the difference. You might have to bump up the IMC voltage (VCCIO) a bit, or the vRAM voltage as well -- certainly. But it doesn't take a lot.

If you're using four slots, I would just buy the fastest RAM you want to use and choose the "auto" default settings for it.

Note that it's been about three years since I delved deep into the current technology of that time, so my knowledge and understanding may be stale. If I build a Comet Lake or similar computer in the next year or so, I'll have to "bone up".

It depends who is offering you this deal. I would strongly recommend to buy only from verified sellers that can be trusted. I am personally buying all this stuff from China and save a lot of money on it.
Trusted sellers from China?

"Save a lot of money" and "verified" sellers in China usually don't go together in the same sentence.
