X-bit Labs heard from AMD that the company now sees that GPGPU accelerators in CPU sockets make no sense, thereby declaring the Torrenza platform dead. Intel on the other hand thinks the opposite (Knights Ferry).
In a conversation with X-bit labs' Anna Filatova, AMD's leading software expert Neal Robison said that Fusion-architecture - which integrates general-purpose [x86] processing cores with highly-parallel stream processors of Radeon GPUs - is a better solution for high-performance computing. According to AMD, "it makes more sense from the software developers standpoint". Besides, it investments into "tool has already been made so we might as well use it". It looks like the once proposed Torrenza platform is no longer even considered as viable.
"APU is a better and cleaner solution than sticking a GPU in the same socket," said Neal Robison.
