Loongson Subsequent-Gen 3A6000 CPUs To Function SMT Help With Zen 3 Efficiency

China’s home chipmaker, Loongson, is about to launch its 3A6000 CPU lineup, and it’s now reported that the processors would assist Simultaneous Multi-Threading (SMT).

Loongson 3A6000 CPU Lineup Anticipated to Compete With Intel’s Alder Lake & AMD Zen 3 Processors

Phoronix reveals that Loongson has added assist for SMT within the newest Linux 6.5 patch. The corporate has included a 2-way SMT assist which can double the thread depend within the upcoming lineup.

SMT assist was included by Intel and AMD processors a number of many years in the past, and what this does is that it splits bodily cores into two threads that execute CPU duties concurrently. This permits a lot quicker efficiency since a single core can carry out two totally different directions concurrently.

Based mostly on what the patch mentions, the Loongson 3A6000 lineup will function a 4C/8T and an 8C/16T  configuration much like what Intel’s tenth Gen & AMD Zen 3 processors included. Other than SMT, the brand new 3A6000 CPUs may even embody assist for SIMD/vectors. The particular extensions are 128-bit LSX and 256-bit LASX. These are customized names for vector processing extension directions. The decisive level would be the impact of such additions on the efficiency of the next-gen lineup.

With this new lineup, Loongson goals to compete instantly with Intel’s Alder Lake & AMD’s Zen 3 CPUs by way of its new “Dragon core” structure. The brand new structure brings a 68% efficiency uplift in single-core (floating-point), which is very large in comparison with what the earlier generations introduced.

The corporate plans on releasing the brand new 3A6000 lineup this yr with earlier stories suggesting a mid-2023 launch which ought to be nearly now. These shall be particularly oriented to Chinese language markets, and whether or not these processors will launch globally is uncertain. Nonetheless, Loongson’s imaginative and prescient is to offer in-house options to customers proudly owning to the latest chips ban. Nonetheless, these processors won’t present related efficiency to international rivals, however they’re getting close to by the seems of it.
