Zotac earlier this week introduced its GeForce RTX 4070 GDDR6 custom-design graphics cards. There are four models in all, based on the company's Twin Edge board design. Two of these are come in the standard black, while the other two are white. Within these, there are regular Twin Edge models that stick to NVIDIA reference clock speeds, while the Twin Edge OC variants come with minor factory overclocked speeds. The highlight here is the memory type. NVIDIA sneaked out variants of the GeForce RTX 4070 with 20 Gbps GDDR6 memory replacing the 21 Gbps GDDR6X that's standard to the RTX 4070.

The Twin Edge board design by Zotac features an aluminium fin-stack heatsink dubbed IceStorm 2.0, which is ventilated by two fans. The regular variants come with a GPU boost frequency of 2475 MHz, while the Twin Edge OC variants come with 2490 MHz GPU boost. Both variants have their GDDR6 memory running at 20 Gbps. The Twin Edge White cards see their cooler shrouds, backplates, and fan impellers don white. All four cards come with some RGB lighting, in the form of a stylized Zotac Gaming graphic on top of the card. VideoCardz reports that these cards are on average $10 cheaper than regular Zotac RTX 4070 Twin Edge series cards.
