While 5G is only coming to French operators, Qualcomm is already in its fourth generation of modem. Today, he unveils his Snapdragon X65 which promises clear improvements at various levels. It also launches its Snapdragon X62 which climbs to 4.4 Gb/s "only". Qualcomm launched its first 5G modem which then promised speeds of up to 5 Gb/s: the Snapdragon X50. The X55 and X60 followed suit, with speeds of up to 7.5 Gb/s.

It is these models that we now find in some of our smartphones. But the future of the range is already in development. Thus, today we discover the Snapdragon X65 capable of reaching 10 Gb/s. For this, it supports the bands below 6 GHz and millimeter frequencies.

It also allows aggregation on all 5G bands, whether above or below 6 GHz, both in FDD  and  TDD. Nothing new here, it was already the case with the Snapdragon X60. But the latter was limited to 200 MHz in the 6 GHz band and 800 MHz in millimeters. The X65 climbs to 300 MHz and 1 GHz.

It also includes a new module for antennas, the QTM545 mmWave. In addition to allowing higher data rates, it offers " support for all millimeter frequencies, including the new n259 (41 GHz) band, while maintaining the same small footprint as the previous generation".

It is also intended to be more economical, thanks to the integration of PowerSave 2.0, based on the recommendations of 3GPP Release 16 and Smart Transmit 2.0; but the technical details are missing on the other hand. The Snapdragon X65 is engraved in 4 nm, against 5 nm previously.

Qualcomm also takes the opportunity to present its Snapdragon X62, a 5G modem "for the general public" with peak speeds of 4.4 Gb/s. It obviously supports frequencies below 6 GHz (120 MHz, 4x4 MIMO and 256-QAM) and millimeter (400 MHz, aggregation of 4 bands, 2x2 MIMO. With PowerSave 2.0 and Smart Transmit 2.0.
