For their RTX3070, MSI has reused the design for their GeForce RTX 3080 Gaming X Trio. The card is dominated by black with some gray highlights. The three fans are 95 mm in diameter. On the other side is a backplate.
Dimensions of the card are 32 x 14 cm.
Installation requires three slots in your system.
Display connectivity options include three standard DisplayPort 1.4a and one HDMI 2.1. The DisplayPort 1.4a outputs support Display Stream Compression (DSC) 1.2a, which lets you connect 4K displays at 120 Hz and 8K displays at 60 Hz. Ampere can drive two 8K displays at 60 Hz with just one cable per display.
Ampere is the first GPU to support HDMI 2.1, which increases bandwidth to 48 Gbps to support higher resolutions, like 4K144 and 8K30, with a single cable. With DSC, this goes up to 4K240 and 8K120. NVIDIA's new NVENC/NVDEC video engine is optimized to handle video tasks with minimal CPU load. The highlight here is added support for AV1 decode. Just like on Turing, you may also decode MPEG-2, VC1, VP8, VP9, H.264, and H.265 natively, at up to 8K@12-bit.
The encoder is identical to Turing. It supports H.264, H.265 and lossless at up to 8K@10-bit.
Unlike the NVIDIA Founders Edition card that uses the new 12-pin power input, MSI sticks to industry standard PCIe power inputs. Together with the PCIe slot, this 8+8 power configuration is specified to supply up to 375 W of power.
The GeForce RTX 3070 does not support SLI. Only the RTX 3090 does, and it has very limit SLI support.
MSI uses six heatpipes that make direct contact with the GPU surface. The main heatsink also provides cooling for the memory chips and VRM circuitry.
The backplate is made out of a plastic/carbon mix, which MSI calls "graphene". It protects the card against damage during installation and handling. Note the thermal pads, which soak up a little bit of heat from the GPU area and VRMs.
Near the top of the card, a metal bracket is attached the the PCB and IO shield, which improved torsion strength of the card to protect against sagging.
An additional heatsink has been placed on the GPU MOSFETs.
