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	GDDR5	GDDR3
Maximum RAM amount	1 GB	512 MB
Memory bus width	32 Bit	256 Bit
Memory clock speed	6 GB/s	1400 MHz
Memory bandwidth	24 GB/s	44.8 GB/s

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

2x DisplayPort 1.4a

2x DVI, 1x S-Video
