Manli Gallardo GeForce RTX 5080 OC

Manufacturer: Manli

The Manli Gallardo GeForce RTX 5080 OC is a high-specification graphics card from Manli, designed around NVIDIA's Blackwell architecture. Built on a 5 nm semiconductor process, the card integrates 45,600 million transistors and operates with a base GPU clock of 2295 MHz, stepping up to a turbo frequency of 2670 MHz under load. RGB lighting is included, and the card measures 359 mm in length and 145 mm in height.

On the memory side, the card carries 16GB of GDDR7 VRAM across a 256-bit bus, reaching an effective memory speed of 30,000 MHz and a peak bandwidth of 960 GB/s. Its 10,752 shading units, 336 texture mapping units, and 112 render output units contribute to a texture rate of 897.1 GTexels/s and a floating-point throughput of 57.42 TFLOPS. The card supports DirectX 12 Ultimate, OpenGL 4.6, ray tracing, DLSS, and Intel Resizable BAR, while connectivity is handled through one HDMI 2.1b port and three DisplayPort outputs, supporting up to four displays simultaneously. The TDP is rated at 360W with a PCIe 5.0 interface.

Pros
  • Supports up to four displays simultaneously, making it well-suited for multi-monitor setups
  • GDDR7 memory with a 960 GB/s bandwidth ceiling and 30,000 MHz effective speed enables substantial data throughput for demanding workloads
  • ECC memory support adds a layer of data integrity for error-sensitive tasks
  • Includes ray tracing and DLSS support, expanding rendering options for compatible applications
  • Intel Resizable BAR support allows the CPU to access the full GPU frame buffer, which can improve data transfer efficiency
  • RGB lighting is present for users who prioritize visual customization in their build
Cons
  • A 360W TDP places considerable demands on the power supply and overall system thermal management
  • The card does not include air-water cooling, so users requiring liquid cooling solutions will need a separate setup
  • No USB-C output is available, limiting connectivity options for displays or devices that rely on that port type
  • At 359 mm in length, physical fitment may be a concern in smaller or mid-tower cases
  • 16GB of VRAM, while substantial, may feel limiting in scenarios where larger frame buffers are increasingly expected
Who is this for?

This card is well-matched to users who run demanding rendering, compute, or multi-display workloads, given its 57.42 TFLOPS of floating-point performance, DPFP support, and ECC memory capability. Content creators and technical users working with large datasets or real-time visualizations will benefit from the 960 GB/s memory bandwidth and 16GB of GDDR7 VRAM, which together support high-throughput data processing. Gamers and developers making use of ray tracing and DLSS will also find the feature set relevant, and those running multi-monitor configurations of up to four displays will appreciate the flexible output options provided by three DisplayPort and one HDMI 2.1b port.

Who is this NOT for?

Users working within compact or small-form-factor cases may find the 359 mm card length a significant fitment obstacle, as not all enclosures can accommodate a GPU of this size. The 360W TDP demands a robust power supply and adequate system airflow, making this card a poor fit for builds with modest power delivery or limited cooling headroom. Additionally, users who specifically require liquid cooling integration will need to source a separate solution, as the card ships with air cooling only and lacks built-in air-water cooling support.
