AMD Radeon R5 M420: specs and benchmarks
Aggregated performance score
Summary
AMD started Radeon R5 M420 sales 1 June 2016. This is a GCN architecture notebook card based on 28 nm manufacturing process and primarily aimed at office use. 4 GB of DDR3 memory clocked at 2 GHz are supplied, and together with 64 Bit memory interface this creates a bandwidth of 16 GB/s.
Compatibility-wise, this is card attached via PCIe 3.0 x8 interface.
It provides poor gaming and benchmark performance at 1.27% of a leader's which is NVIDIA GeForce RTX 4090.

Size and compatibility
Information on Radeon R5 M420's compatibility with other computer components. Useful when choosing a future computer configuration or upgrading an existing one. For notebook video cards it's notebook size, connection slot and bus, if the video card is inserted into a slot instead of being soldered to the notebook motherboard.
| Interface | PCIe 3.0 x8 |
Memory
Parameters of memory installed on Radeon R5 M420: its type, size, bus, clock and resulting bandwidth. Note that GPUs integrated into processors have no dedicated memory and use a shared part of system RAM instead.
| Memory type | DDR3 | |
| Maximum RAM amount | 4 GB | of 192 (Radeon Instinct MI300X) |
| Memory bus width | 64 Bit | of 19000 (GeForce RTX 3080 12 GB) |
| Memory clock speed | 2000 MHz | of 23000 (GeForce RTX 4080 SUPER) |
| Memory bandwidth | 16 GB/s | of 3276 (Aldebaran) |
| Shared memory | - |
Video outputs and ports
Types and number of video connectors present on Radeon R5 M420. As a rule, this section is relevant only for desktop reference graphics cards, since for notebook ones the availability of certain video outputs depends on the laptop model, while non-reference desktop models can (though not necessarily will) bear a different set of video ports.
| Display Connectors | No outputs |
API support
APIs supported by Radeon R5 M420, sometimes including their particular versions.
| DirectX | 12 (11_1) | |
| Shader Model | 5.1 | |
| OpenGL | 4.6 | |
| OpenCL | 1.2 | |
| Vulkan | 1.2.131 |
