AMD

After the announcement of AMD Smart Access Memory, the NVIDIA team quickly made up the gap and added an equivalent called Resizable Bar. First for their RTX 3060 graphics cards (the basic ones, with no Ti index), and today for the entire RTX 3000 series (including 3060 Ti, 3070, 3080 and 3090). The new technology expands the PCI-Express standard, so that the processor gets access to the entire memory of the graphics card instead of 256 Megabytes chunks.

This should improve the performance in supported games, increasing the average FPS and significantly reducing FPS drops. Now we will tell you how to install it, and if the marketing promises turned out to be true.

In modern motherboards BIOS, you can find the Above 4G Decoding checkbox, and now the Resizable Bar has appeared next to it. And the Resizable Bar was already well explained by AMD – the processor can directly communicate with the card through a couple of big steps, instead of a million tiny ones.

But what then is Above 4G Decoding and is it equal to Resizable Bar? No article on the internet explains the term precisely, but I will try to make the best explanation possible.

Over a month ago, AMD announced an event where they planned to showcase the new BIG NAVI cards based on the RDNA2 architecture. After the event, the prices and key specs of the Radeon RX 6800, 6800 XT and 6900 XT were revealed, but even now we have more questions than answers.
