Hello.. Read this: I have posted in my previous post that: Memory Models: x86 is TSO, TSO is "Good" But here is more benchmarks about relaxed memory models compared to SC model: Read carefully: Architecture Support and Scalability Analysis of Memory Consistency Models in Network-on-Chip based Systems "From the experiments, it can also be observed that the reduction in the relative execution times under relaxed memory models like WC, RC, and PRC over the SC model is expected to be 3.33 percentage points approximately for each doubling of the core count up to 128 cores. The relaxed memory models could exploit the increasing parallelism in the larger networks beyond the 64-cores by reordering and pipelining the memory operations. Similarly, for the TSO and PSO models Figure 4.37 suggests that this can be projected to 1.0 percentage points for each doubling of the core count up to 128 cores. In general, the performance gain of the relaxed memory consistency models can be even higher than the experimental values when the system size is further increased.
