Xiaomi launched the Redmi K20 earlier this week, which will launch in the UK as the Xiaomi Mi 9T and India as the Pocophone F2. The K20 Pro features a Snapdragon 855 but the standard model has the latest upper-midrange chipset from Qualcomm, the Snapdragon 730.
The chipset is so new that there are currenlty only 2 phones announced using it. So how do they compare?
Snapdragon 730 vs Snapdragon 730G

Technically, these phones are not like for like with their chipset. The Galaxy A80 sits a notch above the K20 as it uses the Snapdragon 730G. According to Qualcomm this G variant brings select Snapdragon Elite Gaming features and an additional 15% graphics boost over Snapdragon 730 for a more powerful gaming experience.
The official specs of the two chipsets don’t appear to differentiate, they use the same GPU and have the same clocked CPUs. It is likely that there have been some tweaks to the Adreno 618 GPU such as increased clocks, which are not listed.
The Antutu benchmarks don’t reveal that much of a difference between the two versions:
Chipset | CPU | GPU | UX | Memory | Overall |
SD730G | 86915 | 66398 | 59023 | 10202 | 222538 |
SD730 | 82585 | 63878 | 55119 | 11531 | 213113 |
Price
There is a big difference in price, Samsung charges a premium for their phones. There is no official UK pricing yet, but expect to pay around £300 for the Redmi K20 and closer to £600 for the Samsung.
Is the Samsung Galaxy A80 £300+ better?

Probably not. I love the A80 design and it will no doubt sell amazingly well, Samsung have great software so will likely have other advantages than just hardware specs. For example, their software probably does a better job with the 48 MP than the Xiaomi.
The Samsung also has that amazing slide and flip camera and it is certainly a design feature that will attract buyers, compared to people that are just concerned with spec and price.
The main advantages the A80 has are:
- Better chipset with the SD730G
- Base RAM of 8GB
- Base storage of 128GB
- Rear & front camera are identical so vastly superior selfies (48MP, 8MP, TOF vs 20MP)
- Larger 6.7-inch screen with a higher resolution of 1080 x 2400 pixels giving an aspect ratio of 20:9
- Faster charging 25W vs 18W
If you were to buy the 8GB/128GB version of the K20 then the price gap will reduce, but it is still going to be large.
What advantages to the Redmi K20 have?
- Arguably a nicer form factor with a 6.39-inch display
- Gorilla Glass 6 vs 3
- 30g lighter
- A triple rear lens with an 8MP telephoto and 13MP ultra wide. The Samsung has just 8MP ultrawide and then a TOF depth sensor
- 3.5mm headphone jack with 24-bit/192kHz audio
- Larger 4000mAh battery, which combined with the smaller screen and slightly slower chipset should result in much better battery performance.
