MSI GeForce RTX 4070 Super Gaming Slim MLG

Manufacturer: MSI

The MSI GeForce RTX 4070 Super Gaming Slim MLG is a graphics card that sits within NVIDIA's Ada Lovelace generation, offering a compact form factor at 307 mm in length and 125 mm in height. Built on a 5 nm semiconductor process with 35,800 million transistors, it targets users who need a capable card in a slimmer chassis without sacrificing modern feature support including ray tracing, DLSS, and RGB lighting.

On the technical side, the card operates at a base clock of 1980 MHz with a turbo frequency of 2475 MHz, and delivers 35.48 TFLOPS of floating-point performance alongside a texture rate of 554.4 GTexels/s. Its 12 GB of GDDR6X memory runs across a 192-bit bus at an effective speed of 21,000 MHz, providing up to 504.2 GB/s of memory bandwidth. Display connectivity includes one HDMI 2.1a port and three DisplayPort outputs, supporting up to four monitors simultaneously, while the card carries a rated TDP of 220W and connects via PCIe 4.0.

Pros

Supports up to four simultaneous displays through a combination of one HDMI 2.1a and three DisplayPort outputs
The slim form factor at 125 mm in height makes it more compatible with compact or space-constrained PC builds
ECC memory support adds a layer of data integrity useful in workloads where memory accuracy matters
Ray tracing and DLSS are both supported, expanding compatibility with modern rendering features in supported applications
Intel Resizable BAR support allows the CPU to access the full VRAM pool at once, which can improve frame delivery in compatible systems
RGB lighting is present for users who want visual customization within their build

Cons

The 192-bit memory bus width is narrower than what some higher-tier cards in this category offer, which limits memory bandwidth scaling
No USB-C output is available, which may be a drawback for users with monitors or devices that rely on that connection type
Air-water hybrid cooling is not supported, so users requiring liquid cooling integration will need third-party solutions
A TDP of 220W places moderate demands on the system power supply, requiring adequate headroom in the overall build

Who is this for?

This card is well-suited to users running demanding rendering workloads and modern gaming titles that take advantage of ray tracing and DLSS, given the hardware-level support for both features alongside a healthy 35.48 TFLOPS of floating-point throughput. The 12 GB of GDDR6X VRAM combined with ECC memory support also makes it a reasonable fit for content creators and technical compute users who need reliable memory integrity during long processing sessions. Additionally, its slim 125 mm height and four-display output capability make it a practical choice for multi-monitor setups inside compact or mid-tower builds where physical space is a consideration.

Who is this NOT for?

Users who require the highest possible memory bandwidth or bus width for large-scale data-intensive workloads may find the 192-bit bus limiting, as it restricts throughput scaling compared to wider configurations. The absence of a USB-C output makes this card a poor fit for users who depend on USB-C-connected displays or VR headsets that rely on that interface. Similarly, those looking to integrate a liquid cooling or air-water hybrid solution directly into the card will need to look elsewhere, as no such cooling option is supported on this model.
