AMD enters IP licensing with Samsung Exynos 2200
The move is set to bring ray-tracing graphics to Samsung’s next mobile phone, the Galaxy S22 as well as providing increased competition to Arm Ltd., a company which had previously enjoyed success licensing Mali graphics to Samsung (see ARM gets a rival as AMD licenses graphics to Samsung). The GPU is dubbed Xclipse and it offers hardware accelerated ray tracing and variable rate shading that were previously only available on PCs, laptops and consoles.

However, rumors have been circulating that the design-in of the GPU, based on AMD’s RDNA 2, had not gone that well with problems of overheating that required the choking back of the clock frequency and the graphics performance. Samsung has denied that there are any problems with the core and launched the Exynos 2200 as its premium mobile processor.
“AMD RDNA 2 graphics architecture extends power-efficient, advanced graphics solutions to PCs, laptops, consoles, automobiles and now to mobile phones. Samsung’s Xclipse GPU is the first result of multiple planned generations of AMD RDNA graphics in Exynos SoCs,” said David Wang, senior vice president of Radeon Technologies Group at AMD.
The processing heart of the chip is based on eight Arm CPU cores; comprising a single powerful Arm Cortex-X2 flagship-core, three performance and efficiency balanced Cortex-A710 big-cores and four power-efficient Cortex-A510 little-cores.
The Exynos 2200 upgraded support for running artificial intelligence software. The neural processor units performance has doubled compared to its predecessor, allowing more calculations in parallel and enhancing the AI performance. The NPU now offers much higher precision with FP16 support in addition to power efficient INT8 and INT16.
Also, the Exynos 2200 integrates a 3GPP Release 16 5G modem supporting both sub-6GHz and mmWave spectrum bands. With E-UTRAN New Radio – Dual Connectivity (EN-DC), which utilizes both 4G LTE and 5G NR signals, the modem can boost the speed up to 10Gbps.
In keeping with improving displays and cameras the Exynos 2200’s image signal processor architecture has been redesigned to support up to 200 megapixels. At 30 frames-per- second, the ISP supports up to 108MP in single camera mode, and 64+36Mp in dual camera mode. It can also connect up to seven individual image sensors and drive four concurrently for advanced multi-camera setups. For video recording, the ISP supports up to 4K HDR (or 8K) resolution.
The multi-format codec decodes videos up to 4K at 240fps or 8K at 60fps and encodes up to 4K at 120fps or 8K at 30fps. In addition, the MFC integrates an AV1 decoder enabling longer playback time. The advanced display solution features HDR10+ adding more dynamic range and depth to the picture and offers refresh rates of up to 144Hz.
The Exynos 2200 is in mass production and is expected to debut in S22 mobile phones.
