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	2 GB	System Shared
Memory bus width	128 Bit	System Shared
Memory clock speed	7000 MHz	System Shared
Memory bandwidth	112.0 GB/s	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	1x DVI, 1x HDMI, 1x DisplayPort	Motherboard Dependent
HDMI	+	no data
