was released with DDR2/3 DRAM support. The designers noted that they would produce a 3B chip with enhanced processing and vector capabilities, with 8 cores, and a 3C for server applications with up to 16 cores. The 8-core Loongson 3B was noted to use the upgraded GS464V core, with extended vector capabilities. This was followed by the Loonson 3C which used 16 GS464V cores. The 3B1000, and related 2I, both failed as processors due to design errors. In May 2013 development of the 3C was suspended, in favour of developing the 3A2000 processor. Later versions In 2015, the 3A1500 and 3B2000 were released using the enhanced GS464E cores. The improved microarchitecture core allowed better performance, reportedly 3 times as fast as the 3A1000, as well as introducing the LoongISA enhanced instruction set. The 3A1500 was for embedded applications, whilst the 3B2000 was for servers and PCs. In 2017 Loongson released the 3A3000. The 3A3000 is designed with quad-core 64-bit and clocked at 1.5 GHz, power consumption is only 30 W. The performance of the 3A3000 is reported to be equivalent to the Intel J1900 processor (released in 2013). In late-2019 the 3A and 3B 4000 series were released. They used the upgraded GS464EV microarchitecture. The processors are designed with four cores, 8MB of L3 cache and operating clocks between 1.8 GHz to 2 GHz. Loongson 3 LoongArch processors In July 2021 the Loongson 3 5000 series was released. The processor series is Loongson's first with their own developed ISA, "LoongArch". The processors announced include the 3A5000, a four-core desktop CPU, and the 3C5000L, a sixteen-core server CPU based on four 3A5000 in a single package. Both CPUs are reported to be fabricated on a 12 nm process. Whilst the processor was noted to be using the GS464V cores initially, due to incompatibility with previous versions, the cores were renamed to LA464 in August 2021. The Register reported that "the 3A5000 is said to be 50 per cent faster and 30 per cent more power efficient" than the preceding 3A4000. Phoronix reports that the 3A5000 CPU is "roughly on a par with the likes of the Intel Core i3 8109U / Core 2 Quad Q9500 / Core i5 750, or Armv8-based Phytium FT-2000". In 2022 Loongson announced their 6000 series processors. The updated processor architecture will use "LA664" cores., and the company noted that the single-core performance will rival that of
