What's the benefit from T-Topology?
Electrons travel with the speed of light and the speed is also constant, so the only thing that adds latency is the way electrons have to travel. Is the distance bigger, then the latency is higher and is it shorter, then the latency is lower. Therefore it sounds quite logical that ASUS wanted to make this travel distane shorter. Of course this is a highly theoretical scenario and in reality engineers also have to deal with clock skew, the quality of the integrated memory controller, the quality of the DIMMs, consistency of voltages and quite a few other things.
Instead of the serial solution which has been used until today ASUS went for a parallel one. Placing DIMMs in all available slots doesn't have such a big impact on latency as well as compatibility like it used to have before. Usually serial data processing is much more vulnerable to synchronisation issues. Furthermore ASUS is promising that they increased memory overclocking capabilities by up to 15 percent with T-Topology. Therefore it is well possible that our well knonwn and excellent memory overclocker Roger "splmann" Tanner, Christian Ney and Hiwa Pouri could break some of their own world recors again.
In order to get an idea how complex the implementation of such a new fundamental technology is we can present to you an image from an ASUS engineer. On this picture you can see different layer tracings. Each and every route has to be checked and if lengthened and shortened if needed.
