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	1250 MHz	no data
Boost clock speed	1468 MHz	1975 MHz
Number of transistors	12,500 million	26,800 million
Manufacturing process technology	14 nm	7 nm
Thermal design power (TDP)	250 Watt	400 Watt
Texture fill rate	375.8	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	IGP	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	16 GB	32 GB
Memory bus width	2048 Bit	256 Bit
Memory clock speed	2000 MHz	16 GB/s
Memory bandwidth	512.0 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	No outputs	1x HDMI, 4x Thunderbolt
HDMI	no data	+

API support

APIs supported, including particular versions of those APIs.

DirectX	12 (12_1)	12 Ultimate (12_2)
Shader Model	6.4	6.5
OpenGL	4.6	4.6
OpenCL	2.0	2.1
Vulkan	1.1.125	1.2
