ls3d5000
loongson 3d5000 is a 32-core cpu for servers, which is packaged together by two 3c5000 silicon dies. the loongson 3d5000 comes with 32 la464 cores and 64mb of on-chip shared cache and supports eight-channel ddr4-3200 memory. it has five high-speed hypertransport interfaces to connect i/o expansion bridge chips, making it possible to build a single/dual/quad-socket server system with up to 128 cores. the chip also integrates a trusted platform module (tpm). the loongson 3d5000, measuring 75.4×58.5×6.5 mm, is packaged in a lga-4129 socket. its cores can run at 2.0ghz and above, with a typical power consumption of 160w and a tdp of no more than 300w. the measured scores of spec cpu2006 base for single and dual-socket servers exceed 400 and 800 points, respectively, while quad-socket servers can reach a score of 1,600 points.
