MSI has released new versions of the GeForce RTX 4070 graphics cards that use 20 Gbps GDDR6 memory, replacing the original 21 Gbps GDDR6X memory. These additions to the Ventus series are intended to offer cost-effective options without greatly reducing performance. The lineup includes four models: the compact Ventus 2X, the larger Ventus 3X, and their overclocked (OC) variants with minor factory overclocks. The packaging clearly shows GDDR6 next to the memory size to indicate the memory type, and the model numbers include the extension E1 (for example, MSI RTX 4070 Ventus 2X E1) to signify the GDDR6 configuration.

The Ventus 2X model has a dual-fan cooling system for efficient thermal management. It measures 24.2 cm in length, 12.5 cm in height, and maintains a 2-slot thickness, making it suitable for systems with limited space. The standard variant runs at a GPU Boost frequency of 2475 MHz, while the OC variant offers a slight increase to 2505 MHz. Both versions are compatible with the MSI Center application, which allows users to unlock higher one-click overclocking speeds for better performance.

The Ventus 3X model uses a triple-fan cooling system for improved heat dissipation. It measures 30.8 cm in length and 12 cm in height, keeping the same 2-slot thickness as the Ventus 2X. The standard Ventus 3X also runs at a 2475 MHz boost frequency, and the OC variant boosts to 2505 MHz. Although slightly larger, the Ventus 3X exceeds NVIDIA's Small Form Factor (SFF)-Ready card requirements by only about 4 mm, making it nearly suitable for compact builds.

Performance tests indicate a minimal performance difference—about 1%—between the RTX 4070 models with 20 Gbps GDDR6 memory and the original RTX 4070 with 21 Gbps GDDR6X memory at a 1440p resolution. This suggests that switching to GDDR6 memory has a negligible impact on real-world gaming performance at the card's intended resolution. Although these new models are launching at prices similar to the original RTX 4070, which has a manufacturer's suggested retail price (MSRP) of around $599 USD, the use of less expensive GDDR6 memory could allow NVIDIA's partners to lower street prices over time.

The decision to use GDDR6 memory in these RTX 4070 models may be due to cost considerations and supply chain factors. By reducing production costs with GDDR6, manufacturers might offer these graphics cards at lower prices in the future. This strategy could make the new models appealing to consumers seeking high performance without a significant price increase.
