Die Shot
AMD's Lockhart GPU uses the RDNA 2.0 architecture and is made using a 7 nm production process at TSMC. With a die size of 197 mm² and a transistor count of 8,000 million it is a small chip. Lockhart supports DirectX 12 Ultimate (Feature Level 12_2). For GPU compute applications, OpenCL version 1.2 can be used. Additionally, the DirectX 12 Ultimate capability guarantees support for hardware-raytracing, variable-rate shading and more, in upcoming video games. It features 1536 shading units, 96 texture mapping units and 32 ROPs.
