At the AMD press event at Computex, it was revealed that these new processors would have up to 32 cores in total, mirroring the 32-core versions of EPYC. On EPYC, those processors have four active dies, with eight active cores on each die (four for each CCX). On EPYC however, there are eight memory channels, and AMD’s X399 platform only has support for four channels. For the first generation this meant that each of the two active die would have two memory channels attached – in the second generation Threadripper this is still the case: the two now ‘active’ parts of the chip do not have direct memory access. This technically adds latency to the platform, however AMD is of the impression that for all but the most memory bound tasks, this should not be an issue (usually it is suggested to just go buy an EPYC for those workloads). While it does put more pressure on the internal Infinity Fabric, AMD ultimately designed Infinity Fabric for scalable scenarios like this between different silicon with different levels of cache and memory access.


Lo único que si esta de locura, es el TDP, que de 180W subió a 250W,. Explicando los nuevos mobos demostrados en COMPUTEX que tienen la ridícula cantidad de 18+ fases de poder.
