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.

Compatibility, dimensions and requirements

Information on 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).

Interface	IGP	PCIe 4.0 x4
Length	274 mm	no data
Width	IGP	1-slot
Supplementary power connectors	no data	None

Memory

Parameters of memory installed: its type, size, bus, clock and resulting bandwidth. Note that GPUs integrated into processors have no dedicated VRAM and use a shared part of system RAM.

Memory type	GDDR6	GDDR6
Maximum RAM amount	8 GB	4 GB
Memory bus width	128 Bit	64 Bit
Memory clock speed	14 GB/s	16 GB/s
Memory bandwidth	224.0 GB/s	128.0 GB/s

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	1x HDMI 2.1, 1x DisplayPort 1.4a
HDMI	no data	+
