Qualcomm's Snapdragon 820 to support 600 Mbps LTE-Advanced, LTE-U, and Quick Charge 3.0 spec which is up to 27% faster at charging than Quick Charge 2.0
Qualcomm's Snapdragon 820 packs 600Mbps LTE and smarter charging — Qualcomm's Snapdragon 820 hype train is getting to be a bit much …
Context & Ripple Effects
This 820 announcement sits at the start of a modem-speed ladder Qualcomm spent the next three years climbing. Two weeks later its chips inside the Nexus 5X and 6P were rated at just half this figure, 300 Mbps on LTE-Advanced; the 820's 600 Mbps peak was the step change that made flagships the showcase for carrier aggregation.
From there the cadence became annual doublings: the standalone X16 modem hit 1 Gbps, the X20 promised 1.2 Gbps, and the X24 reached 2 Gbps — all before the Snapdragon 855 reframed the roadmap around multi-gigabit 5G rather than squeezing more out of LTE.
First-order effects
- Flagship handset makers building on the 820 can market 600 Mbps downloads and access to unlicensed spectrum via LTE-U, while Quick Charge 3.0 gives their chargers a measurable 27% speed claim over Quick Charge 2.0 devices still on shelves.
- Carriers deploying LTE-Advanced gain a chip-level customer base for their fastest network tiers, since the modem ceiling no longer caps what their radio upgrades can deliver.
Second-order effects
- Rival chipset vendors shipping 300 Mbps-class parts face a spec-sheet gap at the premium tier, pressuring them to match Qualcomm's modem roadmap or cede flagship designs.
- LTE-U puts Qualcomm's silicon directly onto unlicensed airwaves shared with Wi-Fi equipment makers, setting up an interference fight that the 600 Mbps marketing makes harder for regulators to ignore.
Third-order effects
- If the doubling cadence holds — 300, 600, 1,000, 1,200, 2,000 Mbps in successive generations — peak LTE rates converge on 5G-class speeds, which is exactly where the 855 landed: the LTE race becomes the bridge technology and marketing runway for 5G handsets.
The trend: Mobile modem peak speeds doubled roughly every product cycle through LTE-Advanced, turning the cellular modem into the primary flagship differentiator until 5G took over that role.
