Manli GeForce RTX 4080 Super Gallardo (M3535+N688)

Manufacturer: Manli

The Manli GeForce RTX 4080 Super Gallardo (M3535+N688) is a graphics card based on NVIDIA's Ada Lovelace architecture, manufactured on a 5nm process with 45.9 billion transistors. It operates at a base clock of 2295 MHz, boosting up to 2550 MHz, and is equipped with 10,240 shading units alongside 320 texture mapping units and 112 render output units, giving it a texture rate of 816 GTexels/s and a floating-point throughput of 52.22 TFLOPS.

On the memory side, the card carries 16GB of GDDR6X across a 256-bit bus, delivering an effective speed of 23,000 MHz and a peak bandwidth of 736 GB/s. It supports DirectX 12 Ultimate, OpenGL 4.6, OpenCL 3, ray tracing, and DLSS, and can drive up to four displays simultaneously through one HDMI 2.1a port and three DisplayPort outputs. Intel Resizable BAR support is included, and the card measures 351 mm in length and 145 mm in height with a thermal design power rating of 320W.

Pros
  • Supports up to four simultaneous displays through three DisplayPort outputs and one HDMI 2.1a port, offering flexible multi-monitor setups
  • ECC memory support adds data integrity protection useful for precision-sensitive workloads
  • DLSS and ray tracing are both supported, enabling hardware-accelerated rendering features
  • Intel Resizable BAR support allows the CPU broader access to GPU memory, which can improve frame delivery
  • RGB lighting is built into the card for those who prefer a visually customized build
  • No LHR restriction is present, so full GPU utilization is available without mining-related limitations
Cons
  • A 320W TDP places significant demand on the power supply and system cooling
  • The card measures 351 mm in length, which may not fit in smaller or mid-tower cases
  • Air-water hybrid cooling is not supported, limiting thermal management to air cooling only
  • There are no USB-C or DVI outputs, which restricts compatibility with certain older or specialized display setups
  • XeSS (XMX) is not supported, limiting access to that particular upscaling option
Who is this for?

This card is well-suited to users running demanding rendering and compute workloads, thanks to its 52.22 TFLOPS of floating-point throughput, DPFP support, and ECC memory, which together make it a reasonable fit for GPU-accelerated professional tasks alongside gaming. The 16GB of GDDR6X VRAM at 736 GB/s bandwidth accommodates high-resolution textures and large datasets, while support for ray tracing, DLSS, and DirectX 12 Ultimate makes it a strong match for users working with visually intensive, modern game titles or real-time 3D applications. Those who need multi-display productivity setups of up to four screens will also find the output configuration practical for broad workspace arrangements.

Who is this NOT for?

The card's 351 mm length makes it a poor fit for users working with compact or small-form-factor cases where physical clearance is limited. Its 320W TDP places substantial load on the system's power delivery and thermal infrastructure, so those with modest or lower-capacity power supplies and limited airflow in their builds may struggle to run it stably. Additionally, users who rely on USB-C or DVI display connections — such as those with older monitors or certain professional display hardware — will find no compatible output on this card, making it unsuitable for such configurations without additional adapters.

Final Verdict

The Manli GeForce RTX 4080 Super Gallardo (M3535+N688) is a capable Ada Lovelace-based graphics card that brings together a strong compute throughput, 16GB of GDDR6X memory at 736 GB/s bandwidth, and a well-rounded feature set including ray tracing, DLSS, and ECC support — making it a credible option for users with demanding rendering, compute, or high-resolution gaming needs. Its physical size and 320W power requirement do impose real constraints on system compatibility, and the absence of USB-C outputs narrows its display flexibility somewhat, but for users with appropriately equipped systems and standard DisplayPort or HDMI displays, it delivers a thorough and well-specified package that addresses both graphics and compute use cases without meaningful compromise in its intended context.
