AMD think abandon Torrenza of Fusion...
After five years of silence, technology Torrenza resurfaced. In principle, explained a few years ago in our columns, it was question of coprocessors to accelerate specific calculations and thus shed the main processor. On paper, this technology had the meaning because based on bus Hyper Transport the caster, which may even be coupled to the PCI Express bus graphics cards.
But Neal Robinson, Director of software solutions for AMD, indicates that Torrenza is finally a good idea. The problem of the implementation of Torrenza is the need to develop applications taking part of these chips to ensure performance to the appointment. A bit like CUDA or OpenCL with the power of additional graphics cards, but five years too early. With the arrival of the AMD Fusion directly integrating the GPU in the same die that the CPU, it is therefore simpler for AMD to this less expensive solution, requiring no specific development. Intel will do the same with his MIC (Many Integrated Core) chipset for Xeon sockets? Not a priori, the MIC as Knights Corner before arriving in 2012...
