Form factor & compatibility
Information on Mobility Radeon HD 2300 and Radeon R5 A255 compatibility with other computer components. Useful when choosing a future computer configuration or upgrading an existing one. For desktop video cards it's interface and bus (motherboard compatibility), additional power connectors (power supply compatibility). 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 1.0 x16 | PCIe 3.0 x8 |
VRAM capacity and type
Parameters of VRAM installed: its type, size, bus, clock and resulting bandwidth. Integrated GPUs have no dedicated video RAM and use a shared part of system RAM.
| Memory type | DDR1/DDR2/GDDR3 | GDDR5 |
| Maximum RAM amount | 128 MB | 1 GB |
| Memory bus width | 128 Bit | 128 Bit |
| Memory clock speed | 800 MHz | 4 GB/s |
| Memory bandwidth | 12.8 GB/s | 64 GB/s |
| Shared memory | - | no data |
Connectivity and outputs
Types and number of video connectors present on the reviewed GPUs. As a rule, data in this section is precise only for desktop reference ones (so-called Founders Edition for NVIDIA chips). OEM manufacturers may change the number and type of output ports, while for notebook cards availability of certain video outputs ports depends on the laptop model rather than on the card itself.
| Display Connectors | No outputs | Portable Device Dependent |
API compatibility
