NVIDIA started T400 sales 6 May 2021. This is a desktop graphics card based on a Turing architecture and made with 12 nm manufacturing process. It is primarily aimed at gamer market. 2 GB of GDDR6 memory clocked at 10 GB/s are supplied, and together with 64 Bit memory interface this creates a bandwidth of 80 GB/s.

Compatibility-wise, this is single-slot card attached via PCIe 3.0 x16 interface. No additional power connector is required, and power consumption is at 30 Watt.

Form factor & compatibility

This section provides details about the physical dimensions of T400 and its compatibility with other computer components. This information is useful when selecting a computer configuration or upgrading an existing one. For desktop graphics cards, it includes details about the interface and bus (for motherboard compatibility) and additional power connectors (for power supply compatibility).

Interface	PCIe 3.0 x16
Width	1-slot
Supplementary power connectors	None

VRAM capacity and type

Parameters of memory installed on T400: its type, size, bus, clock and resulting bandwidth. Note that GPUs integrated into processors have no dedicated memory and use a shared part of system RAM instead.

Memory type	GDDR6
Maximum RAM amount	2 GB	of 192 (Radeon Instinct MI300X)
Memory bus width	64 Bit	of 8192 (Radeon Instinct MI250X)
