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	4096	3840
Core clock speed	1574 MHz	no data
Boost clock speed	1720 MHz	1975 MHz
Number of transistors	13,230 million	26,800 million
Manufacturing process technology	7 nm	7 nm
Thermal design power (TDP)	475 Watt	400 Watt
Texture fill rate	440.3	474.0

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	PCIe 3.0 x16	PCIe 4.0 x16
Length	no data	267 mm
Width	Quad-slot	Quad-slot
Supplementary power connectors	None	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	HBM2	GDDR6
Maximum RAM amount	32 GB	32 GB
Memory bus width	4096 Bit	256 Bit
Memory clock speed	1612 MHz	16 GB/s
Memory bandwidth	825.3 GB/s	512.0 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, 4x USB Type-C	1x HDMI, 4x Thunderbolt
HDMI	+	+
