Snapdragon 4 Gen 4 is the stronger platform on paper: Qualcomm lists 5G, a 4 nm process and LPDDR5 support, while UNISOC’s T7250 is an LTE platform built on 12 nm with LPDDR4X support. In benchmark results reported by 91mobiles, Snapdragon 4 Gen 4 also scores higher. Those differences help compare the chips, but they do not guarantee how two finished phones will perform.

Which platform is faster in benchmarks?
91mobiles reports higher AnTuTu and Geekbench 6 results for Snapdragon 4 Gen 4 than for UNISOC T7250. The following figures are from that site’s comparison material, retrieved in 2026; its reviewed material does not establish a publication year or enough test setup detail to treat the scores as results from matched phones in controlled conditions.
| Benchmark | Snapdragon 4 Gen 4 | UNISOC T7250 |

| Geekbench 6 multi-core | 2,333 | 1,480 |
These are third-party reported scores, not official Qualcomm or UNISOC results. They indicate an advantage for Snapdragon in this comparison, but should not be read as an exact measure of how much faster one retail phone will feel. Benchmark versions, phone cooling, software, memory, storage and the test device can all affect results. 91mobiles comparison; 91mobiles T7250 material.

What the differences mean when choosing a phone
5G versus LTE
Choose based on the actual handset’s connectivity and your carrier. Snapdragon 4 Gen 4 supports a 5G modem system; the T7250 platform is LTE. 5G availability and performance depend on the phone’s supported bands, regional configuration, network coverage and signal, so verify the specific model rather than relying on the chipset name alone.
Process node and memory generation
The listed 4 nm process and LPDDR5 support give Snapdragon the more advanced platform specifications compared with the T7250’s 12 nm process and LPDDR4X support. Those labels alone do not establish battery life or everyday speed: power use and responsiveness also depend on the phone’s implementation and workload.

Fairphone Gen. 6+ 12GB/256GB Modular Unlocked Android Phone-Forest Green
- Designed to Be Repaired, Not Replaced: The Fairphone Gen. 6+ is built around a 12-part modular design, so you can swap the battery, screen, speaker, or cameras yourself with just a screwdriver instead of replacing the whole phone. It's backed by a hardware warranty of up to five years and software support through 2033.
- Smooth Performance, Serious Durability: Powered by Snapdragon 7s Gen 4 and 12GB RAM, keeping apps fast and multitasking smooth. The 120Hz OLED display makes scrolling feel buttery, not choppy, and Gorilla Glass 7i plus IP55 splash-resistant means it can handle what your last phone couldn't. There's 256GB built in (expandable up to 2TB), so you're never trading photos for space.
- Less Noise, More You: Fairphone Moments lets you switch between full Android and a distraction-free mode with up to five essential apps of your choice. Working, traveling, or spending time with the people who matter - you decide what shows up on your screen, and what stays out of reach.
- US Carrier Compatibility: This Android smartphone supports AT&T and T-Mobile, and supported MVNOs on those networks. It is not supported on Verizon or Verizon-network MVNOs. 5G speeds require a 5G-enabled SIM/eSIM and supporting data plan, and availability varies by carrier and location.
- Google's Gemini AI Assistant, Built In: Use Gemini Live to identify what's in front of your camera, summarize the group chats you're behind on, or plan your day. Not interested in AI? You can easily toggle it off. Your phone, your call.
CPU and graphics
UNISOC publishes a specific six-core-plus-two-core CPU arrangement for T7250, while Qualcomm’s cited page gives Snapdragon’s maximum CPU clock but not its core layout. Avoid comparing core counts or inferring a complete architecture from that incomplete specification. Qualcomm identifies an Adreno GPU and graphics APIs; UNISOC names the Mali-G57 and its maximum frequency. Neither set of platform figures guarantees gaming performance in a particular phone.

- Price, actual RAM and storage capacity, and whether storage uses eMMC or UFS.
- Display panel and resolution; the T7250’s supported display modes do not mean every T7250 phone implements them.
- Battery capacity, charging, software version and update-support commitments.
- Carrier bands and 5G or LTE configuration for your market.
- Cooling and sustained performance, especially if you play games or run demanding apps.
- Camera sensors and image processing; platform camera support is not the same as a specific phone’s camera quality.
No specific retail phone models or prices are established for this comparison, so the chipset specifications alone are not enough to recommend one handset over another.
