The DDR5 RAM memory is going to come out on the market in a trickle and we will have the opportunity to see how a few models take over it. Why? Well, because there is some discouragement with the sales of Alder Lake despite Intel’s efforts to sell it as a quantum leap. Technologically it is, without a doubt, and there is only one section that will not be: a single monolithic die. Regarding RAM memory, dual support will bring about certain limitations, but with overclock it seems another story …
Intel will destroy AMD on DDR bandwidth, and latency?
What is shared today refers to an Intel Core i9-12900K with a set of GIGABYTE memories that carry speeds of DDR5-6200. This in itself is a very high speed for the IMC, since it only supports serially DDR4-3200 and in DDR5 up to 4,800 MHz.
It is not a surprise as such, it was even expected given certain rumors of speeds from the manufacturers and even so it is impressive the ability to overclock that they will implement to be the first generation that supports them.
This in itself will presumably destroy the current AMD Ryzen in bandwidth, since with this speed rates of 110,000 or 115,000 MB / s should be reached without too much problem (at least on paper).
What we do not know is the general latency of the system between the IMC and the DDR5 itself, an aspect that has always penalized AMD and where Intel had an advantage. We will have to wait to know it, since in gaming it is important.
Intel’s new BMI is a beast, it holds up to 8,000 MHz!
The leaked reveals that with CPU-Z open, the Intel IMC is capable of supporting 4.004 MHz in Windows with a 1:30 divider and with latencies of 50-50-50-100-150-2T. This is a brutal overclock both to the RAM chips and to the controller itself, since going from 4,800 MHz to 6,200 MHz the current modules seem to require 1.5 volts or more, which is 400 mV of difference.
We do not know the voltage introduced at 8,000 MHz, but what is certain is that it will be enormous and that those memories are with liquid nitrogen, but it is still a world record.
It remains to be seen if they are capable of passing a stress test or at least a benchmark and above all, knowing the bandwidth they produce at that speed and latencies.
There is less to know if indeed, Intel has launched a good platform and CPUs, or if instead it is just a patch until the arrival of its renewed architecture. What is clear is that it began by promising very little and for now it is surprising, we will see if it ends up giving the bell.
