QCN6274 vs QCN6024: A Comprehensive Comparison Between Wi-Fi 7 and Wi-Fi 6 Chips ...

Both QCN6274 and QCN6024 are Qualcomm wireless networking chipsets, but they belong to two completely different Wi-Fi generations: Wi-Fi 7 (802.11be) and Wi-Fi 6 (802.11ax).
The differences between them are not limited to speed improvements alone — they reflect a full generational evolution in wireless standards, RF architecture, bandwidth capability, latency optimization, and multi-device concurrency performance.

This article provides a detailed comparison of the two chipsets from the perspectives of product positioning, technical specifications, hardware architecture, and application scenarios.

1. Product Positioning: Two Different Wi-Fi GenerationsQCN6024: Mainstream Wi-Fi 6 Platform

Released around 2020, QCN6024 belongs to Qualcomm’s Wi-Fi 6 “Pine” platform series.
It was widely adopted in:

• Home routers

• Mesh Wi-Fi systems

• SMB access points

• Enterprise wireless devices

Built around the 802.11ax standard, QCN6024 significantly improved wireless efficiency, OFDMA scheduling, MU-MIMO performance, and network capacity compared to Wi-Fi 5. However, its architecture was designed specifically for Wi-Fi 6 and does not include hardware support for future Wi-Fi 7 features.

• Designed for high-capacity and low-interference wireless environments

The addition of 6GHz enables:

• Wider clean spectrum

• Lower interference

• Larger channel bandwidth

• Higher throughput

• Better multi-device performance

2.2 Channel BandwidthQCN6024

• Maximum channel width: 160MHz

• Peak theoretical throughput: approximately 4.8Gbps (4×4 MIMO)

QCN6274

• Supports 320MHz ultra-wide channels

• Peak theoretical throughput: up to 11.5Gbps

Compared to QCN6024, QCN6274 nearly doubles the available channel bandwidth and significantly improves data capacity for high-density environments.
