Snapdragon 4 Gen 2 is the more capable platform on the specifications and aggregate benchmark results available: it adds 5G, uses a listed 4 nm process, supports UFS 3.1, and has a newer CPU configuration than the LTE-only Snapdragon 665. That does not guarantee every 4 Gen 2 phone will outperform every 665 phone: cooling, memory, software, and other handset choices influence real-world speed and battery life.
Snapdragon 4 Gen 2 vs Snapdragon 665: key differences
| Specification | Snapdragon 4 Gen 2 | Snapdragon 665 | What it means |
|---|---|---|---|
| Process | 4 nm, according to Qualcomm | 11 nm, according to Qualcomm | The 4 Gen 2 is built on the newer, smaller process. Process size alone does not establish a phone’s battery life. |
| CPU | 64-bit Kryo CPU with 2 performance cores up to 2.3 GHz and 6 efficiency cores up to 2 GHz; Qualcomm also notes a 2.4 GHz version | Kryo 260 octa-core CPU up to 2 GHz, with 4 performance and 4 efficiency cores | The listed 4 Gen 2 configuration has a higher peak clock and a different core arrangement; sustained performance depends on the handset. |
| GPU | Adreno GPU; Qualcomm’s product brief lists Vulkan 1.1 API support | Adreno 610 | Qualcomm’s product pages do not provide a directly comparable gaming score, so a precise GPU uplift cannot be established from them. |
| Mobile network | Snapdragon X61 5G modem; sub-6 GHz; maximum listed downlink 2.5 Gbps and uplink 900 Mbps | Snapdragon X12 LTE modem; maximum listed downlink 600 Mbps | 5G support is the clearest connectivity difference. These are platform maximums, not expected everyday speeds. |
| Storage support | UFS 3.1, 2-lane support listed | Not stated on the Qualcomm product page reviewed | Check the phone’s actual storage type and configuration before treating this as a device-level advantage. |
| Display support | Up to FHD+ at 120 Hz listed | Not stated on the Qualcomm product page reviewed | Platform support does not mean every phone using the chip ships with that display capability. |
| Charging | Quick Charge 4+ listed | Quick Charge 3.0 listed | Actual charging speed depends on the phone, charger, and manufacturer implementation. |

These are NanoReview-reported aggregate results from its Snapdragon 4 Gen 2 and Snapdragon 665 pages, not scores from a controlled test of two otherwise identical phones. The pages do not establish one shared test protocol for both chips. Benchmark version, phone cooling, memory, software, and the devices represented in the samples can affect scores. Treat the results as an indication that the 4 Gen 2 leads in the reported aggregates, not as a guarantee of a particular speed difference between two phones.

What the comparison means for 5G, gaming, and battery life
5G connectivity
Snapdragon 4 Gen 2 includes Qualcomm’s Snapdragon X61 5G modem with sub-6 GHz support; Snapdragon 665’s listed modem is LTE. The 4 Gen 2 is the clear option if 5G is required, but confirm that the specific phone supports the bands used by your carrier and region. Modem maximum rates do not predict the connection you will get in a particular place.
Gaming and sustained performance
The CPU specifications and aggregate scores favor the newer platform, but the available Qualcomm product pages do not establish a directly comparable GPU gaming uplift. A phone’s cooling system, graphics settings, screen resolution, memory, and software can alter gaming performance, particularly during longer sessions. Compare sustained gaming results from the actual models you are considering rather than assuming the chipset name alone settles the question.

Battery life and charging
A 4 nm process versus 11 nm is a platform distinction, not a battery-life measurement. Battery capacity, display, modem use, software, and device tuning all matter to endurance. Likewise, support for Quick Charge 4+ or Quick Charge 3.0 does not tell you how quickly a particular phone charges: the handset and compatible charger determine the implementation. Qualcomm describes Quick Charge as designed to increase a device’s battery charge by up to 50% in 15 minutes and cautions that results vary by device design; this is a vendor claim, not a measured comparison of these two chipsets.

If you are choosing between two phones and all other factors are comparable, Snapdragon 4 Gen 2 is the stronger platform based on its listed 5G capability, CPU configuration, storage support, and the aggregate scores above. The Snapdragon 665 remains an LTE platform, so a phone built around it may still make sense if its price, condition, or other device features suit your needs better.

Compare the handset details that a processor comparison cannot settle:
- Price and regional availability of the exact phone model.
- RAM and storage capacity, plus the actual storage standard used.
- Display resolution and refresh rate.
- Battery capacity and measured endurance.
- Charging hardware included with the phone and its real charging behavior.
- Thermal behavior and sustained gaming performance.
- Carrier-band compatibility for 5G or LTE in your region.
- Software version and update support.
- Benchmark results from the same benchmark version on comparable handset models.
For example, NanoReview lists the Xiaomi Redmi 13 5G among phones using Snapdragon 4 Gen 2, but check the exact regional model: variants under the same phone name can differ. NanoReview’s chipset page provides that device listing.
How much weight should you give Qualcomm’s performance claim?
Qualcomm says Snapdragon 4 Gen 2 offers “up to 10% better performance” than Snapdragon 4 Gen 1. That is a comparison against the previous 4-series generation, not Snapdragon 665, so it does not quantify the gap between the two chips in this comparison. For Snapdragon 4 Gen 2 versus Snapdragon 665, the benchmark figures above are aggregate third-party results rather than a controlled head-to-head test.
