No matter how good the RAM memory you install in your PC is, in the end its performance will always depend on the memory controller integrated in the processor (IMC); the BMI It is a digital circuit that controls the flow of data that goes between the processor and the RAM memory, and the fact that it is integrated into the processor allows RAM management to be carried out in a more direct and faster way than when these controllers were integrated into the motherboard.
AMD, on the throne of RAM performance with Cezanne and her BMI
In the screenshot above you can see in the memory benchmark of Aida64 to an eight-core AMD Cezanne APU (for some reason they have covered the exact model, and that is because its launch is expected precisely for the 5th of this month; in any case, based on the core count and the speed it seems clear that it is a AMD Ryzen 7 5700G) paired in all likelihood with dual channel DDR4 RAM (we cannot know exactly either since the capture is cropped precisely in the part where the RAM information appears).
This level of performance is quite impressive, at the height of systems with quad-channel memory and that of course leaves everything that Intel and AMD had in the market until now, well, until systems with RAM memory arrive. DDR5 dual channel performance of DDR4 RAM is around 50-60MB / s.
There is not much time left until we can confirm these data if in the end it is true that AMD launches in just two days, but if so, we would be above all a milestone in the history of those in red because as we mentioned at the beginning, traditionally AMD It has always been well behind Intel when it comes to the performance of its memory controller, be it on APU or CPU.
AMD Cezanne: the Ryzen 5000 with Zen 3 and RDNA2
According to the leaks that have been happening in recent weeks and months, AMD will initially present three models of Cezanne APUs based on the new Zen 3 architecture and with RDNA 2 graphics.
On the one hand we have the AMD Ryzen 3 5400G that carries 4 cores and 8 processing threads at a base frequency of 4 GHz and 4.2 GHz turbo, with 8 MB of L3 cache, Vega 5 graphics and a 65W TDP. We also find the Ryzen 5 5600G with 6 cores and 12 threads at 3.9 GHz base and 4.4 GHz Turbo, accompanied by 16 MB of L3 cache, Vega 7 graphics and 65W of TDP. Finally, the flagship APU would be the Ryzen 7 5700G with 8 cores and 16 threads at 3.8 GHz base and 4.6 GHz Boost, with 16 MB of L3 cache, integrated graphics Vega 8 at 2.1 GHz and also 65W by TDP.
Now that we know the memory performance data of these APUs, there is no doubt that AMD Cezanne becomes much more attractive than until now, but as always when we are facing a leak we must take the information carefully and we have no choice but to wait for the official confirmation of the manufacturer to be able to take the data as good.
