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.

Pipelines / CUDA cores	1408	768
Boost clock speed	1645 MHz	2321 MHz
Number of transistors	6,400 million	5,400 million
Manufacturing process technology	7 nm	6 nm
Thermal design power (TDP)	100 Watt	53 Watt
Texture fill rate	144.8	111.4

Size and compatibility

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	PCIe 4.0 x8	PCIe 4.0 x4
Length	180 mm	no data
Width	2-slot	1-slot
Supplementary power connectors	1x 6-pin	None

Memory

Parameters of VRAM installed: its type, size, bus, clock and resulting bandwidth. Integrated GPUs have no dedicated VRAM and use a shared part of system RAM.

Memory type	GDDR6	GDDR6
Maximum RAM amount	3 GB	4 GB
Memory bus width	96 Bit	64 Bit
Memory clock speed	14000 MHz	16 GB/s
Memory bandwidth	168.0 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	1x HDMI, 3x DisplayPort	1x HDMI 2.1, 1x DisplayPort 1.4a
HDMI	+	+

API support

List of supported APIs, including specific versions.
