Manli GeForce RTX 4080 Super (M3520+N701)

Manufacturer: Manli

The Manli GeForce RTX 4080 Super (M3520+N701) is a graphics card built on NVIDIA's Ada Lovelace architecture, fabricated at 5 nm and integrating 45,900 million transistors. It carries 16GB of GDDR6X VRAM across a 256-bit memory bus and has a thermal design power of 320W. The card measures 320 mm in width and 138 mm in height, and does not include RGB lighting.

Performance figures include a base clock of 2295 MHz boosting to 2550 MHz, yielding 52.22 TFLOPS of floating-point throughput alongside a texture rate of 816 GTexels/s and a pixel rate of 285.6 GPixels/s. The 10,240 shading units are paired with 320 texture mapping units and 112 render output units, while memory operates at an effective speed of 23,000 MHz for a maximum bandwidth of 736 GB/s. Feature support covers DirectX 12 Ultimate, OpenGL 4.6, OpenCL 3, ray tracing, DLSS, stereoscopic 3D, ECC memory, Double Precision Floating Point, and Intel Resizable BAR, with three DisplayPort and one HDMI 2.1a output enabling up to four simultaneous displays.

Pros
  • 16GB of GDDR6X VRAM running at 23,000 MHz effective speed delivers 736 GB/s of memory bandwidth, supporting demanding rendering and compute tasks
  • Ray tracing and DLSS are both hardware-supported, enabling advanced visual effects and upscaling in compatible applications
  • ECC memory support adds data integrity protection for compute-sensitive workloads
  • Double Precision Floating Point capability broadens the card's usefulness to professional and scientific compute scenarios
  • Intel Resizable BAR is present, facilitating more efficient data transfers between the CPU and GPU
  • Four simultaneous display outputs via three DisplayPort and one HDMI 2.1a port support multi-monitor configurations
Cons
  • A 320W TDP places considerable demands on system power delivery and case thermal management
  • At 320 mm in length, the card requires adequate case clearance and may not fit in smaller enclosures
  • No RGB lighting is included, which limits visual customization options
  • USB-C, DVI, and mini DisplayPort outputs are absent, restricting compatibility with certain display types
  • Air-water hybrid cooling is not supported, confining thermal solutions to standard air cooling only
Who is this for?

This card is well-suited to users who need substantial GPU compute capacity alongside strong rendering performance, as its 52.22 TFLOPS of floating-point throughput combined with Double Precision Floating Point and ECC memory support make it a capable choice for both high-end graphics workloads and professional compute applications. The 16GB of GDDR6X VRAM with 736 GB/s of bandwidth provides the memory headroom needed for large textures, complex scenes, and data-intensive tasks. Users who require multi-monitor setups of up to four displays will also find the output configuration directly accommodating without additional hardware.

Who is this NOT for?

Users working with compact or smaller mid-tower cases may find the 320 mm length a practical obstacle, as it requires sufficient internal clearance to install correctly. The 320W TDP makes this card a poor fit for systems with limited power delivery or constrained airflow, since it places real demands on both the power supply and the overall thermal environment. Additionally, users who prefer a visually customized build will find no RGB lighting on this model, and those relying on USB-C or DVI display connections will need to consider alternative output options, as neither is available here.
