Boost clock speed	980 MHz	2105 MHz
Number of transistors	2,410 million	23,000 million
Manufacturing process technology	28 nm	7 nm
Power consumption (TDP)	15 Watt	255 Watt
Texture fill rate	31.36	606.2
Floating-point performance	526.8 gflops	no data

Form factor & compatibility

Information on compatibility with other computer components. Useful when choosing a future computer configuration or upgrading an existing one. For desktop graphics cards it's interface and bus (motherboard compatibility), additional power connectors (power supply compatibility).

Interface	IGP	PCIe 4.0 x16
Width	IGP	2-slot
Supplementary power connectors	no data	2x 8-pin

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	System Shared	GDDR6
Maximum RAM amount	System Shared	16 GB
Memory bus width	System Shared	256 Bit
Memory clock speed	System Shared	16 GB/s
Memory bandwidth	no data	512.0 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	No outputs	1x HDMI, 2x DisplayPort, 1x USB Type-C
HDMI	no data	+
