Oppo K13 5G

Under the hood, the Oppo K13 5G is powered by the Snapdragon 6 Gen 4 chipset, featuring 8GB of LPDDR4X RAM and up to 256GB of UFS 3.1 storage. The smartphone also has a graphite sheet for heat dissipation and a DC cooling system that helps keep the device cool under stress.
The Oppo K13 5G scores 711,000 points on AnTuTu 10 and 986/2,873 points in the single/multi-core Geekbench 6 CPU performance test. These aren’t exceptional scores, but given the segment and price tag the device belongs to, they’re not worth ignoring either.
We’ve also run a couple of video games on the Oppo K13. While playing BGMI at Smooth + Extreme (60 fps) settings, we got an average frame rate of around 58.7 fps. On the other hand, we could run Genshin Impact at 42.4 fps. Moreover, the handset provides decent performance for everyday use and casual gaming.

Infinix Note 50s 5G

Unlike the Oppo K13 5G, the Infinix Note 50s 5G features a Dimensity 7300 Ultimate chip with 8GB of LPDDR5X RAM and up to 256GB of UFS 2.2 storage.
The company claims an AnTuTu 10 score of 700K+ points, but we’ve often seen Dimensity 7300-powered phones max out at around 650K points on the benchmark.
The chipset’s performance also depends on the level of optimization. In the past, we’ve seen the CMF Phone (1) (review) offering 120 fps gameplay on BGMI, making it the only phone in the under Rs. 20,000 segment to do so.
From what it looks like, the Oppo K13 5G and the Infinix Note 50s 5G should offer similar day-to-day performance, with the former being slightly faster at loading apps, thanks to its UFS 3.1 storage.

When it comes to battery life, the Oppo K13 5G really redeems itself. The handset, unlike any other model in the segment, sports a 7,000 mAh Si/C battery that supports 80W wired charging.
