Detailed specifications

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	384	768
Boost clock speed	1100 MHz	2321 MHz
Number of transistors	no data	5,400 million
Manufacturing process technology	14 nm	6 nm
Power consumption (TDP)	15 Watt	53 Watt
Texture fill rate	no data	111.4

Form factor & compatibility

Information on Radeon RX Vega 6 (Ryzen 2000/3000) and Radeon RX 6400 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). For notebook video cards it's notebook size, connection slot and bus, if the video card is inserted into a slot instead of being soldered to the notebook motherboard.

Interface	no data	PCIe 4.0 x4
Width	no data	1-slot
Supplementary power connectors	no data	None

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	no data	GDDR6
Maximum RAM amount	no data	4 GB
Memory bus width	no data	64 Bit
Memory clock speed	no data	16 GB/s
