Ryzen 3900X Simple User
99.9% Intel only makes .. AMD is a complete beginner, look at it ^^
The third generation of Ryzen came to think of subcomms for encoding (or replacement).
The 9900K is the best on the Intel side (except for professional CPUs), but it's roughly 60-65
3700X, the same number of cores / threads, will save 40 ~ 44 won and save about 200,000 won
I ordered the 3700X. I was stuck in the motherboard selection.
You could use the B450 at a cheaper price, but you still wanted to pick an X570 for the future.
More expensive than Intel's cheap Z390 boards. (The meaning of price ratio is getting weaker. ㅠㅠ)
Then, a few days ago in Comzon, I sold a little cheaper 3900X, which had been expensive due to out of stock.
We just gave up the cost and decided to go to 3900X, which is definitely different from Intel.
The motherboard was picked up by the Asrock X570M Pro4, which is the only M-ATX board currently (I like the small case).
It's small and pretty, but the biggest downside is that it's a chipset cooler that's almost all on the X570 boards.
Unconditionally back to the top .. When the children are quite noisy loud. ㅠ
(If you are a low noise user, please check the chipset cooler noise when choosing an X570 board.)
It's small, but there are three M.2 terminals (one above is for a wireless LAN card. Actually two ^^)
One comes with a heatsink as standard. Buy an SSD with a heatsink and install it at the bottom for ventilation.
But when I put on VGA, the M.2 heatsink side is completely covered by VGA. Rather, heat is likely to accumulate.
Almost close to the chipset heatsink ;;;
There's also almost no 1mm gap in the ram socket side.
ATX and M-ATX are slightly different, such as ease of assembly;
Maybe ITX is more comfortable (so M-ATX is getting smaller, and ITX seems to be a few high-end)
The most troublesome part of choosing this board was the weakest power supply on the X570.
It looks good on the outside, but it's cheaper than the higher model, so there are many criticisms that it's a disadvantage.
If the power supply is weak, the temperature will rise when the load is high, and then the performance will decrease.
It's common to see Intel 9 *** K CPUs on the cheaper Z390 boards.
There is also a decent power X570 ITX board, but the price is over 30.
So ... Anyway, this Zen 2 has no manual over margin, so I decided to use it purely and decided on this board.
Looking back at the international users, the 3900X is very good at turning (How about the 3950X?)
This time a little work goes into the case, first of all is a nude test.
The chipset cooler noise was unforgivable, so I removed it and put a small Noktua fan on it. It's almost silent
Heatsink is quite hot when I touched the power supply when it was loaded.
I decided to put an additional pan. This is very good effect ^^ (It's just a temperature lower than performance ..)
As an aside, I've just used Focus, not Power +
It's pretty much the same, except it's a semi-modular and a zero fan. Very quiet and nice.
We are testing with only PBO turned on.
The improvement in performance as the number of cores increases is obvious.
However, there are also minor compatibility issues that are 0.2% incomplete than Intel.
(If you put Cinebench R15 under multiple folders, you can't save errors, Daum Pod encoder is not an old version, etc.)
Important work, no problem with the latest programs.
The other difference is that the boot is 10-15 seconds slower than Intel. If you are sensitive to boot speed Intel recommend
After all, AMD really got a lot better, but I still recommend Intel to people who are at the Communist level.
Lastly, I don't play games and mainly use office programs. I tried encoding for comparison.
Shana Encoder, Convert Encoding Time for iPad High Definition
The file is an original 4.66G. This is an error that sometimes bounces files over 4G on iPad Nplayer.
1.3900X 12C / 24T (Pure, PBO +, 240mm water cooled)
Allcore ~ 41 times, maximum temperature 77 ~ 86 ℃ (depending on the water cooler fan speed setting), 7 minutes 20 seconds
(Allcore is about 0.5 higher than running Cinebench. Because I don't use 100% of CPU.)
Allcore ~ 44 times, Maximum temperature ~ 94 ℃, 17 minutes 40 seconds
(It's made for almost no noise, so the temperature is abnormally high. ㅠ)
Allcore ~ 40 times, Maximum temperature ~ 52 ℃, 25 minutes 30 seconds
(Large air-coolers are the safest to use reasonably.)
In encoding, the number of threads is a gang. ㄷㄷㄷ
In order to improve performance, it consumes a lot of electricity, and it is natural that the temperature increases.
I think CPU temperature is okay.
But it's not yet a complete BIOS / driver yet (when will AMD be near perfect from release)
CPU temperature at idle is also 45-50 ℃, which is almost 15-20 ℃ higher than Intel.
It was the first 7 nm CPU, so people had high expectations, but it wasn't over well as it was, and the temperature was high.
Nevertheless, it's just as cheap as me, even if it's a pure board, it's worth the core investment. (A little bit cheaper!)
If the current state of pure (automatic) loads the maximum load allcore 40.5 times, usually single core ~ 45-46 times multiple times,
The optimized bios / driver comes out quickly, increasing the allcore multiple by one or two,
I hope the temperature management will be smarter.
PS) There are a lot of things that are not displayed properly.
There is no CPU core temperature on HWMonitor. On this board, TMPIN7 on the board is the CPU temperature.
(HWinfo comes out properly, but the letters are so small that I can't write.)
In the Corsair iCUE, Asrock ~ Temperature # 6 is the CPU temperature. If you have any manual settings please note ^^
------------------------ Add
I tried to do a manual over, but I can't find a good article like Intel.
I gave up because it seemed to be much less than the time I spent.
Still, I thought it might be a good idea to turn on PBO (Precision Boost Overdrive).
There is no problem or dissatisfaction with anything else (the latest bios).
I noticed the difference when I offset the CPU Vcore Votage with PBO on.
Voltage or power is constantly changing, so at first glance it looks like Auto or Offset.
So what was comparable was the result (performance value) and the CPU maximum temperature.
Offset -0.1V, the idle temperature drops to 37 ~ 50 ℃, and the maximum temperature under load is definitely reduced.
However, the performance is also a bit poor .. It is -2.9% based on CineBench and -1.14% based on encoding time.
Comparing roughly, the difference between 9900K 50 multiples (good yield) and 48 multiples (basic yield) is about 4.2% ;;;
In conclusion, if you don't know about manual overload or bother, just turn on PBO,
If you prefer low temperature (= quiet fan sound), you may want to use an additional voltage offset.
