Qualcomm gives details on Snapdragon 855, its smartphone chipset: X24 modem, which isn't 5G compatible, 7 nanometer for 20% better graphics, and AI improvements
The Verge :
Context & Ripple Effects
A day after Qualcomm's unveiling of the Snapdragon 855 promised "multi-gigabit 5G" support, the detailed spec sheet lands with a clarifying wrinkle: the chip's integrated X24 modem is not 5G-compatible, meaning any 5G claim rests on pairing the 855 with a separate modem rather than on-die integration. The rest matches the annual playbook Qualcomm set with last year's Snapdragon 845 — a smaller process node (7nm), a graphics bump around 20%, and another step up in on-device AI performance.
First-order effects
- Phone makers building 2019 flagships on the 855 get the 7nm graphics and AI gains out of the box, but must add a discrete 5G modem to deliver on the "multi-gigabit 5G" positioning from the launch announcement.
Second-order effects
- With 5G living outside the main SoC, device cost, board space, and battery budgets become the battleground where 5G-capable flagships differentiate — and rival silicon vendors' integrated-modem roadmaps turn into a direct selling point against Qualcomm's two-chip approach.
Third-order effects
- If each generation keeps leading with AI multiples — 3X here, and larger claimed jumps in the later Gen 1 and Gen 2 reveals — flagship chipset competition structurally shifts from connectivity specs toward on-device AI throughput as the headline metric buyers and reviewers track.
The trend: Flagship mobile chipsets are turning into annual AI-compute races, with 5G arriving first as a bolt-on modem before integration catches up.
