At the press conference on October 28, amd officially launched the new product of radon RX 6000 Series graphics card based on rnda 2 architecture.In addition to the dazzling parameters, the black technology, known as "infinite cache" and "smart memory access", has aroused our keen expectation for new graphics cards.Interestingly, it has been reported recently that NVIDIA is also researching similar technologies for RTX 30 series GPUs, and then push them through software updates.

For users who want to build a "3A platform" platform, amd radon RX 6000 series GPU will get a mysterious bonus when it is matched with Zen 3 Ruilong 5000 Series CPU and x570 chipset.

It is reported that this benefits from 128MB of inity cache on the new graphics card, rage mode (in essence, the over frequency profile in the radon software), and "intelligent memory access" technology.

Amd claims that smart memory access technology allows dynamic expansion of CPU and video memory (VRAM) data channels, with an overall performance improvement of up to 11%.


However, NVIDIA also said that similar technologies it was working on could enable RTX 30 series ampere GPUs to achieve similar results with AMD or Intel processors.

In today's typical PC configuration, GPU usually protects a small portion of the frame buffer (usually 256MB) to the PCIe bus, while the "smart memory access" technology refers to the "scalable basic access register" (bar).

Although mad has always claimed that this technology is unique to rnda 2 GPU, NVIDIA said in a recent interview with gamersnexus that its ampere GPU also supports the size adjustable bar, which can bring similar performance improvement after being enabled.

Obviously, this means that RTX 30 series graphics cards can also be supported by subsequent software updates. Unfortunately, NVIDIA has yet to disclose the exact timetable.
