RDNA 2 [20] (also RDNA2) [21] is the successor to the RDNA microarchitecture. It was first publicly announced in early 2020 with a projected release in Q4 2020. [21] [22] According to statements from AMD, RDNA 2 would be a "refresh" of the RDNA architecture. [23] More information about RDNA 2 was made public on AMD's Financial Analyst Day on ...
Driver updates and support stopped at AMD Catalyst 14.4 for video cards with support up to DirectX 11 on Hardware, and 10.2 for DirectX 9.0c cards.

RDNA 2 was first publicly announced in January 2020 with AMD initially calling RDNA 2 a "refresh" of the original RDNA architecture from the previous year. [2] At AMD's Financial Analysts Day held on March 5, 2020, AMD showed a client GPU roadmap that gave details on RDNA's successor, RDNA 2, that it would again be built using TSMC's 7 nm ...
Mode Based Execution Control (MBEC) is an extension to x86 SLAT implementations first available in Intel Kaby Lake and AMD Zen+ CPUs (known on the latter as Guest Mode Execute Trap or GMET). [10] The extension extends the execute bit in the extended page table (guest page table) into 2 bits - one for user execute, and one for supervisor execute.
The Navi GPUs are the first AMD GPUs to use the new RDNA architecture, [6] whose compute units have been redesigned to improve efficiency and instructions per clock (IPC). It features a multi-level cache hierarchy, which offers higher performance, lower latency, and less power consumption compared to the previous series.
As of July 2017, the Graphics Core Next instruction set has seen five iterations. The differences between the first four generations are rather minimal, but the fifth-generation GCN architecture features heavily modified stream processors to improve performance and support the simultaneous processing of two lower-precision numbers in place of a single higher-precision number.
The preview included RDNA 3 running gameplay of Lies of P, AMD CEO Lisa Su confirming that a chiplet design would be used, and a partial look at AMD's reference design for an RDNA 3 GPU. [ 3 ] Full details for the RDNA 3 architecture were unveiled on November 3, 2022 at an event in Las Vegas .
AMD was the first to introduce the instructions that now form Intel's BMI1 as part of its ABM (Advanced Bit Manipulation) instruction set, then later added support for Intel's new BMI2 instructions. AMD today advertises the availability of these features via Intel's BMI1 and BMI2 cpuflags and instructs programmers to target them accordingly. [2]
