It all started with NVIDIA, who decided Follow the steps that led to AMD to great success by designing the reconstruction of Threadripper and its Ryzen Series processors, by introducing MCM construction to its graphics cards. Let's look at what it means for your graphics card to have this kind of design.
What is MCM?
MCM stands for Multi-Chip-Module, and it actually eliminates the single-use monolithic architecture that AMD and NVIDIA have been using on their GPUs for decades and moved to design based on a few dedicated chips
Divide and you will succeed. This is the growing concept of MCM design in GPUs, which allows multiple "small GPUs" to be installed in the same package, which is linked to high bandwidth programs.
Historically, the development of high-performance GPU computing is closely related to the quality of transistors. As you Moore's law slowed down and the number of dead transistors no longer increases with breakneck speed, the operating curve of individual monolithic GPUs seems to have reached the point of gain.
However, as the need for more powerful GPUs continued to increase, a decision was made to implement MCM construction on GPUs. Therefore, they are integrated at the mortality level many GPU modules to build logical GPUs
Specifically, GPUs are divided into basic GPU modules (GPM) which is easy to produce, combines it with die and technology that marks the a High bandwidth and energy efficiency, achieves significant performance improvements.
Of course, using this model of GPU architecture involves something beauty; According to NVIDIA, the project offers a 45,5% performance increase
So if my graphics card is MCM is it better?
The answer is yes, it's better than if you have a traditional monolithic GPU, as long as NVIDIA only uses this build for its high-quality graphics cards.
Basically, the design allows them to have an increase in performance that would not be possible with monolithic GPUs, which is why we only see it in the top drawings.
