MSI GeForce RTX 4080 Super Suprim X

Manufacturer: MSI

The MSI GeForce RTX 4080 Super Suprim X is a graphics card rooted in Nvidia's Ada Lovelace architecture, produced on a 5 nm process with 45,900 million transistors. It runs at a base clock of 2295 MHz and pushes up to 2640 MHz under turbo conditions, making it one of the higher-clocked variants in its line. The card includes RGB lighting, ray tracing, DLSS, DirectX 12 Ultimate support, and the ability to drive up to four displays, while its dimensions of 336 mm in length and 142 mm in height reflect a substantial physical build.

Memory configuration consists of 16GB of GDDR6X VRAM on a 256-bit bus running at an effective 23,000 MHz, resulting in a maximum bandwidth of 736.3 GB/s. The 10,240 shading units are complemented by 320 texture mapping units and 112 render output units, translating to a texture rate of 844.8 GTexels/s, a pixel rate of 295.7 GPixel/s, and 54.07 TFLOPS of floating-point performance. ECC memory and Double Precision Floating Point (DPFP) support are both present, and connectivity is covered by three DisplayPort and one HDMI 2.1a output, with Intel Resizable BAR support included and a TDP of 320W over PCIe 4.0.

Pros
  • A turbo clock of 2640 MHz places this among the higher factory-overclocked variants in its generation, with floating-point performance rated at 54.07 TFLOPS
  • 16GB of GDDR6X VRAM across a 256-bit bus provides substantial memory capacity for rendering and compute-heavy workloads
  • ECC memory support and DPFP capability extend its usefulness to precision-sensitive compute applications
  • Ray tracing and DLSS are both supported alongside DirectX 12 Ultimate, covering a broad range of modern rendering features
  • RGB lighting is built in, and up to four displays can be connected simultaneously via three DisplayPort and one HDMI 2.1a output
Cons
  • At 336 mm in length and 142 mm in height, the card demands considerable physical space and may not fit in many mid-tower or compact cases
  • A 320W TDP places heavy demands on the system power supply and requires adequate airflow to maintain stable operation
  • No air-water cooling option is available, leaving thermal management fully dependent on the card's air-cooling solution
  • USB-C video output is absent, limiting compatibility with displays that rely on that connection type
  • XeSS (XMX) is not supported, restricting hardware upscaling to DLSS only
Who is this for?

The MSI GeForce RTX 4080 Super Suprim X is well-suited to users running high-throughput rendering and compute workloads, where its 54.07 TFLOPS of floating-point performance, DPFP support, and ECC memory capability provide a reliable and capable foundation. Content creators and technical users working with large assets or memory-intensive pipelines will benefit from the 16GB of GDDR6X VRAM and 736.3 GB/s of bandwidth, while those needing multi-display setups can take advantage of four simultaneous outputs. The inclusion of ray tracing, DLSS, and DirectX 12 Ultimate also makes it a solid fit for visually demanding real-time 3D work.

Who is this NOT for?

At 336 mm in length and 142 mm in height, this card is a poor fit for compact or mid-tower builds where physical clearance is limited, as case compatibility will need to be verified carefully before installation. The 320W TDP also rules it out for systems with constrained power delivery or limited airflow, particularly since no air-water cooling option is available and the card depends entirely on air cooling. Users who require USB-C video output or XeSS upscaling support will additionally find those capabilities absent here.

The Suprim X is built on the Ada Lovelace architecture, using a 5 nm manufacturing process that accommodates 45,900 million transistors. It connects via PCIe 4.0 and carries a TDP of 320W, with cooling handled exclusively by air as no air-water cooling option is provided. The card measures 336 mm in length and 142 mm in height, representing a notably large physical footprint that will require careful case compatibility planning.

Final Verdict

The MSI GeForce RTX 4080 Super Suprim X is a thoroughly specified graphics card that combines a high factory overclock with a broad and capable feature set. Its 54.07 TFLOPS of floating-point performance backed by 16GB of GDDR6X memory, ECC support, and DPFP capability give it genuine range across both demanding visual workloads and precision compute tasks. The 336 mm length and 320W TDP do place real constraints on system compatibility, making careful build planning a necessity rather than an option — but for users with setups that can accommodate it, the Suprim X delivers a well-rounded and high-performing card that earns its place in serious creative and compute-oriented configurations.
