AMD was once criticized for its FX processors and the "vincyj core" strategy. Now everything has changed – the latest Ryzen systems crush the competition in multi-threaded applications. And this is not the end of the manufacturer's possibilities …
The latest generation of AMD processors has doubled the number of cores available – the Ryzen 9 3950X offers 16 cores, and the Ryzen Threadripper 3990X will offer as many as 64 cores. Will the manufacturer apply a similar strategy for the next generation of systems? The secret of this topic was lifted by Mark Papermaster, AMD Technology Director, who was interviewed by Tom’s Hardware.
AMD sees no limit when introducing more cores in processors
Papermaster was asked about the limit of increasing cores and whether it would make sense to introduce 32-core models in a consumer platform.
"In the consumer platform, there is no limit to increasing the number of cores – that's why: it all depends on the time and that the software is adapted to support multiple cores. We have now overcome this obstacle and more and more applications can use many cores / threads.
In the near future I do not see any saturation level for the cores. However, you need to be very careful when adding more cores, because they cannot be added before the application can use them. As long as the balance is maintained, I think we will continue to observe the trend of increasing the number of cores. "
Will more AMD Ryzen processors offer even more cores?
Does this mean that more AMD Ryzen processors will offer even more cores? Papermaster did not say it directly, but it is likely. However, we can conclude from the interview that we should not expect the introduction of support for four threads per core (SMT4), which was suggested by some leaks. This solution is used in servers, but according to AMD CTO there are still many applications that are not able to use its potential.
The technology director also noticed that Moore's law is slowing down, which is why the Infinity Fabric bus was introduced, allowing you to flexibly add more CPU and GPU kernels. However, we know that it will need to be improved in the near future so that it can keep up with the new higher-bandwidth interfaces (including DDR5 and PCI-Express 5.0).
In an interview, the editors also raised other issues – including shortages of AMD processors, Epyc server units or Intel Optane memory. If interested, please refer to article on Tom’s Hardware.
