[gmx-users] Pme on gpu performance

I would like to ask what performance improvement is expected for  
future releases (e.g. 4.6) for PME calculations on gpu cards. Last  
week I sent benchmark results for dhfr to the list, which show no  
performance gain when the newest versions of tesla cards vs intel xeon  
R are used (more or less in agreement of what is presented on the  
gromacs website). However, for the same system  simulations with  
different gpu code, acemd,  on a very similar machine can be about 5  
times faster, as benchmarked recently by my colleagues, suggesting  
that performance of gromacs may soon improve. is that correct ?
