NVIDIA has officially launched a scalable bar support, which is expected to improve performance in some games. For many years, resizable bar has been a part of PCI Express specification, but amd only recently supported it as an important function and introduced smart access memory.
AMD's smart access memory effectively enables its ryzen 5000 processor to directly access the GPU memory to bypass the I / O bottleneck. This allows the CPU to access the full graphics frame buffer instead of just reading 256 MB blocks.
Amd has previously promised to increase performance by an extra 10% in some games if its new ryzen 5000 CPU is used with the latest ryzen RX 6000 graphics card.
Intel and NVIDIA now seem to have cooperated to achieve the same function on Intel Architecture PC. NVIDIA will adopt the third generation max-q technology in its new RTX 3000 series notebook computers.
Traditionally, max-q is a kind of notebook GPU that can be slightly cooled and quieter by reducing part of its performance. This allows high-performance GPU to be installed in a thinner notebook and keep good heat dissipation. Therefore, in RTX It's interesting to see this memory access technology bundled with it in 3000 mobile series. I hope this technology will also appear in desktop GPU / processor combination.
