At today’s CES exhibition, amd officially launched the sharp dragon threaddriver 3990x processor, which is the first desktop 64 core 128 thread processor, which greatly improves the work efficiency of content creators and is of great significance. What’s more, amd also unlocked an achievement this time, making CPU performance about 10 times that of five years.
The shredder 3990x not only has 64 cores and 128 threads (eight CPU dies plus one IO die), but also has a total of 288mb cache, including 32MB Level 2 cache and 256MB Level 3 cache. The benchmark main frequency is 2.9ghz, and the maximum acceleration is 4.3ghz. The thermal design power consumption is not disclosed, but the official said that it is still 280W TDP.
At the press conference, amd also showed a lot of running points, especially AMD’s favorite cinbench R20 multi-threaded running points in the past year. The 3990x of 64 core 128 threads ran 25399 points, almost double the 3960x of 24 cores and about 5 times of core i9-9900k.
This is not the end. If you count forward, Intel’s hedt platform processor flagship in 2013 was core i7-4960x. At that time, it was only 6 cores and 16 threads, and its cinbach R20 score was less than 2000, less than 1 / 10 of the current level, even for hedt platforms of the same level.
Of course, we should also see the gap. The number of cores / threads of the threaddropper 3990x is 10 times that of the processor 6 years ago. At present, the performance improvement of CPU is basically realized by multi-core parallel, and the performance of single core is far less obvious than that of multi-core parallel.
In addition, if the current software ecology can’t keep up, the parallel performance of multi-core CPUs will not go up, because the number of cores from the 32 core sharp dragon threaddropper 3970x to the sharp dragon threaddropper 3990x has doubled, and the performance improvement is only about 50%. Obviously, there is a problem with the growth rate. On the one hand, it is because of the sharp dragon threadripper The acceleration frequency of 3990x is low, but the parallel efficiency of multi-core CPU is more important.
From this point of view, it may be difficult for future zen3 and zen4 processors to significantly increase the number of CPU cores. Even if the technology can be achieved, the efficiency of multi-core parallel will meet a bottleneck sooner or later.
