The Card

At first glance, the card follows Zotac's GeForce 30 AMP Holo design theme almost exactly. The colors on the card are black with various shades of gray. Running along the top edge is a Spectra RGB lighting element, which creates amazing RGB effects. On the back, you'll find a high-quality metal backplate that curves into the sides.


Dimensions of the card are 35.5 x 15 cm, and it weighs 1864 g. This is a very long card; please be aware of the dimensions and check if it will fit your case.


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.


Zotac has equipped their card with a dual-BIOS feature; the two BIOS chips are clearly recognizable on the board. Unlike all other vendors, Zotac doesn't provide a physical BIOS switch. Rather, you have to install the Zotac Firestorm software to toggle between the default "Performance" BIOS and a secondary "Quiet" BIOS.


Unlike the NVIDIA Founders Edition card that uses a 12-pin power input, Zotac sticks to industry standard PCIe power inputs, using a 8+8+6 configuration. Combined with PCIe slot power, this configuration is rated for 450 W. When unpacking the card, you're greeted by a sticker on the power plugs that makes it crystal clear that you're supposed to use three separate power cables.


Zotac has been including this "super cap" for a while on some of their high-end graphics cards. It's a capacitor with extra-large capacity that can store energy and release it quickly, which is supposed to help smoothen out GPU voltage. We tested it a few years ago, and it made no noticeable difference in anything (including overclocking) even though the smoother voltage can be measured with the proper equipment.

If this really makes any difference other than looking super shiny, other graphics card vendors would have certainly picked up on the technology.


The GeForce RTX 3070 Ti doesn't support multi-GPU.

Teardown

Zotac's thermal solution uses eight heatpipes. The main heatsink not only cools the GPU, but also provides cooling for memory chips and VRM circuitry. The thermal pads on the VRM are 2.3 mm thick, and those on the memory are 2.0 mm thick.


The backplate is made out of metal and protects the card against damage during installation and handling. The thermal pads for the memory chips on the back are 4.0 mm thick.


As you can see, a lot of space is wasted near the end of the card for a plastic cooler shroud that really doesn't add anything except to make the card longer, which complicates installation in some cases.
