Although AMD has only launched its Zen 2 APUs in the OEM market, their RYZEN PRO series of APUs (R5 4650G and R7 4750G) is now available for purchase in Hong Kong as tray CPUs (R5: HK$1799 / US$232 ; R7: HK$2680 / US$345). Hong Kong tech forum HKEPC has purchased the R7 4750G for testing against its non-APU and Intel equivalents, R7 3700X and i7 10700 respectively.

Personal commentary
From the CPU benchmark results, the 4750G consistently performs on par with the 3700X, both leaving the 10700 in the dust. In some tests, the 4750G even beats the 3700X despite its lower L3 cache, possibly due to its SOC design instead of the 3700X's chiplet design and minimising latency. From the GPU benchmark results, the Vega 8 on the 4750G is consistently on par with the RX 550 and ahead of the Vega 11 on the 3400G and GT 1030. (Of course, Intel's UHD 630 is completely crushed.)
In my opinion, if you are only a very casual gamer or do not require much GPU horsepower (such as office work and studying), the 4750G is an excellent buy. For HK$280 / US$36 when compared to the 3700X, you get a GPU which can handle basic 1080p gaming, satisfying needs for light gaming between work or study sessions. When compared to the 10700, the 4750G is HK$30 / US$4 more expensive, directly competing with the 10700, but what you get is a significantly more capable CPU and GPU, CPU/GPU/RAM overclocking support and more. There is simply no reason to buy the 10700 as it is basically irrelevant in the competition. I am also anticipating the results for the 4650G, as it is probable that it is also much more compelling than the already not-so-attractive 10400.
N.B. above price figures and comparisons are based on retail prices (about the same in various retailers) in Hong Kong as of date of writing. Current HK retail price of 3700X and 10700 are HK$2400 / US$309 and HK$2650 / US$342 respectively.
N.B. this is assuming the RYZEN PRO APUs are available for purchase in your market. Otherwise, these would need to be determined by prebuilt systems' prices.
