Qualcomm Snapdragon 415 vs 425 vs 618 vs 620: specs comparison
Qualcomm just unveiled its newest batch of chipsets - the Snapdragon 415, 425, 618, and 620. As usual with processors, a surplus of numbers usually drown us and one can easily get lost among all the specs. That's why we decided to treat you to a straightforward representation of the specs sheets that Qualcomm has provided. In the first table right below, you can see some of the more important specs of the new range of chipsets.
| Chipset | CPU | GPU | Memory | DSP |
| Snapdragon 415 | 8 x Cortex-A53 cores (<1.4GHz) | Adreno 405 | LPDDR3@667MHz eMMC 4.5 SD 3.0 (UHS-I) | Hexagon™ V50 DSP |
| Snapdragon 425 | 8 x Cortex-A53 cores (<1.7GHz) | Adreno 405 | LPDDR3@933MHz eMMC 5.1 SD 3.0 (UHS-I) | Hexagon™ V50 DSP |
| Snapdragon 618 | 2x Cortex-A72 (<1.8GHz) + 4 x Cortex-A53 (<1.2GHz) | "Next-gen" Adreno | Dual channel LPDDR3 (933MHz) | Hexagon™ V56 DSP |
| Snapdragon 620 | 4 x Cortex-A72 (<1.8GHz) + 4 x Cortex-A53 (<1.2GHz) | "Next-gen" Adreno | Dual channel LPDDR3 (933MHz) | Hexagon™ V56 DSP |
Moving on to the rest of the specs sheets, we get to compare the LTE connectivity capabilities of Qualcomm's newest. Judging from the specs, all of these (save for the Snapdragon 415) are pretty even-stevens.
| Chipset | Modem | LTE Category | Theoretical data transfer speeds | Dual LTE SIM support | VoLTE |
| Snapdragon 415 | Qualcomm X5 LTE | Cat.4 | 150Mbps download; 50Mbps upload | ✓ | × |
| Snapdragon 425 | Qualcomm X8 LTE | Cat.7 | 300Mbps download; 100Mbps upload | ✓ | ✓ |
| Snapdragon 618 | Qualcomm X8 LTE | Cat.7 | 300Mbps download; 100Mbps upload | ✓ | ✓ |
| Snapdragon 620 | Qualcomm X8 LTE | Cat.7 | 300Mbps download; 100Mbps upload | ✓ | ✓ |
We are not done yet, mind you. The rest of the connectivity features of Qualcomm newest have not slipped under our noses. As you can see, the two Snapdragon 400 representatives are endowed with similar features, and so are the ones of the 600 series.
| Chipset | Wi-Fi | Bluetooth | GPS | |
| Snapdragon 415 | 802.11ac (2.4/5.0GHz) Multi-User MIMO (MU-MIMO) | BT4.1 + BLE | IZat™ Gen8C Lite | |
| Snapdragon 425 | 802.11ac (2.4/5.0GHz) Multi-User MIMO (MU-MIMO) | BT4.1 + BLE | IZat™ Gen8C Lite | |
| Snapdragon 618 | Qualcomm® VIVE™ 1-stream 802.11ac | Bluetooth Smart v4.1 | IZat™ Gen8C | |
| Snapdragon 620 | Qualcomm® VIVE™ 1-stream 802.11ac | Bluetooth Smart v4.2 | IZat™ Gen8C | |
Last, but certainly not least, we have put together the video/display capabilities of the new chipsets. Just as expected, the brand-new Snapdragon 620 is the most potent of the bunch, as it is able to record 4K video at 30 frames per second as well as 1080p one at no more than 120fps. It also supports two image signal processors (both of which can be up to 21MP in size). The show-stopping feature is its ZSL support - ZSL, if you don't know, stands for "zero shutter lag" and allows you to take a picture as soon as you tap the shutter button.
| Chipset | Video | Camera | Display | |
| Snapdragon 415 | 1080p@30fps playback (w/ HEVC); Full HD H.264 capture | Single ISP; up to 13MP | Up to 720p | |
| Snapdragon 425 | 1080p@30fps playback (w/ HEVC); Full HD H.264 capture | Dual ISPs; up to 21MP | Up to 1080p | |
| Snapdragon 618 | 4K@30fps / 1080p@120fps capture; H.265 encoding/decoding | Dual ISPs; up to 21MP (930MP/s output) | Up to Quad HD | |
| Snapdragon 620 | 4K@30fps / 1080p@120fps capture; H.265 encoding/decoding | Dual ISPs; up to 21MP (930MP/s output); ZSL@24fps | Up to Quad HD | |
