Among mainstream desktop processors, the 10-core 2006-2016 period has been up to 4 core (4 core 8 threads), in 2017 with AMD back to the high-performance CPU market, THE CPU finally began nuclear war, two years the mainstream desktop market has become 8 core-based.
In the server market, AMD’s “nuclear bomb” is even harder, the Naples neapolitan family’s first EPYC dragon processor is 32 core 64 thread, this year’s 7nm Zen2 architecture of the Rome Roman processor reached 64-core 128 threads, And you co-commerce’s strong server CPU is still the most 28 core 56 thread.
The desktop market also doubled again, with the 16-core 32-threaded Ryzen 9 3950X replacing the previous 8 cores entering the mainstream market, while the HEDT platform already has 24-core, 32-core Ryzen Threadripper 3960X, 3970x, But the 64-core 128-threaded Reyon Threadripper 3990X is no longer a secret, or is waiting for release next year.
And then what? Will the desktop double to 128 threads after it reaches 64 cores? If so, this can only be done by AMD.
In an interview, Forrest Norrod, AMD’s senior vice president and general manager of data center and embedded business, also responded to future CPU core developments, saying, “Over time, AMD wants to continue to improve the number of CPU cores as the manufacturing process improves.” Many applications can benefit from an increase in core numbers and an increase in computational density. “
In other words, AMD is hinting that the cpu core numbers in the future will break through the current level, and 128 core 256 threads are also possible.
But Forrest Norrod is also cautious because the improvement in computing performance is not just a matter of increasing the number of cores, and he says AMD also needs to ensure balance in compute density, memory bandwidth, IO interfaces, and so on to avoid bottlenecks in some parts.
As things stand, AMD’s next-generation 7nm-plus-process Zen3 should not add the core number, partly because the existing desktop 16 core, server 64 core is enough, and partly because Zen3 is using the 7nm enhanced version of the process, although the transistor density increased by 20%, However, the overall increase is not sufficient to support the doubling of the CPU cores.
Then there is the Zen4 architecture, AMD is still in development, as soon as 2021 to come out, when it should be used on the 5nm process, its transistor density increased by about 80%, this upgrade is likely to support the CPU core doubled.
