The decision to move to a chiplet-based GPU microarchitecture was led by AMD Senior Vice President Sam Naffziger who had also lead the chiplet initiative with Ryzen and Epyc. [6] The development of RDNA 3's chiplet architecture began towards the end of 2017 with Naffziger leading the AMD graphics team in the effort. [ 7 ]
Zen 3 is the last microarchitecture before AMD switched to DDR5 memory and new sockets, which are AM5 for the desktop "Ryzen" chips alongside SP5 and SP6 for the EPYC server platform and sTRX8. [3] According to AMD, Zen 3 has a 19% higher instructions per cycle (IPC) on average than Zen 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 process and would be coming in 2020. [3] AMD told their investors that they were targeting a 50% uplift in performance-per-watt and increased IPC with the RDNA 2 ...
Smart Access Memory enables potential performance boosts on systems that use both AMD Ryzen CPUs and Radeon video cards. [7] Radeon Enhanced Sync reduces screen tearing like v-sync, but it avoids capping frame rates at the monitor's refresh rate. This can reduce the input lag associated with v-sync. This is limited to DirectX 9, 10, and 12. [12]
RDNA 3 (also RDNA3) is the successor to the RDNA 2 microarchitecture and was projected for a launch in Q4 2022 per AMD's gaming GPU roadmap. [46] [47] [48] At an August 29 reveal event for Ryzen 7000 series CPUs, AMD CEO Lisa Su teased RDNA 3 and revealed that it would utilize chiplets built on TSMC's N5 node. [49]
The Ryzen family is an x86-64 microprocessor family from AMD, based on the Zen microarchitecture. The Ryzen lineup includes Ryzen 3, Ryzen 5, Ryzen 7, Ryzen 9, and Ryzen Threadripper with up to 96 cores.
ROCm [3] is an Advanced Micro Devices (AMD) software stack for graphics processing unit (GPU) programming. ROCm spans several domains: general-purpose computing on graphics processing units (GPGPU), high performance computing (HPC), heterogeneous computing.
As of February 2015, only AMD's "Kaveri" A-series APUs (cf. "Kaveri" desktop processors and "Kaveri" mobile processors) and Sony's PlayStation 4 allowed the integrated GPU to access memory via version 2 of the AMD's IOMMU. Earlier APUs (Trinity and Richland) included the version 2 IOMMU functionality, but only for use by an external GPU ...
