Technical specs
General performance parameters such as number of shaders, GPU core base clock and boost clock speeds, manufacturing process, texturing and calculation speed. These parameters indirectly speak of performance, but for precise assessment you have to consider their benchmark and gaming test results. Note that power consumption of some graphics cards can well exceed their nominal TDP, especially when overclocked.

Size and compatibility
Information on Radeon 550X Mobile and UHD Graphics 770 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 3.0 x8 | Ring Bus |
| Width | no data | IGP |
Memory
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 | GDDR5 | System Shared |
| Maximum RAM amount | 4 GB | System Shared |
| Memory bus width | 64 Bit | System Shared |
| Memory clock speed | 6000 MHz | 1550 MHz |
| Memory bandwidth | 48 GB/s | no data |
| Shared memory | no data | - |
Video outputs and ports
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 | No outputs |
API support
List of supported graphics and general-purpose computing APIs, including their specific versions.
