MSI GeForce RTX 4080 Super Gaming Slim specifications and in-depth review

MSI GeForce RTX 4080 Super Gaming Slim

Manufacturer: MSI

The MSI GeForce RTX 4080 Super Gaming Slim is a graphics card based on NVIDIA's Ada Lovelace architecture, manufactured on a 5nm process with 45,900 million transistors. It runs at a base clock of 2295 MHz with a turbo boost reaching 2550 MHz, and supports ray tracing, DLSS, DirectX 12 Ultimate, and multi-display output for up to four screens. RGB lighting is built in, Intel Resizable BAR is supported, and the card connects to the system via PCIe 4.0 — all within a slim-profile design measuring 322mm in length and 136mm in height.

On the memory side, the MSI GeForce RTX 4080 Super Gaming Slim is equipped with 16GB of GDDR6X VRAM across a 256-bit bus, achieving an effective memory speed of 23000 MHz and a peak bandwidth of 736.3 GB/s, with ECC memory support also included. Its 10240 shading units, 320 TMUs, and 112 ROPs contribute to a floating-point throughput of 52.22 TFLOPS, a texture rate of 816 GTexels/s, and a pixel rate of 285.6 GPixel/s. Connectivity is handled by two HDMI 2.1a ports and two DisplayPort outputs, with no USB-C, DVI, or mini DisplayPort options present, and the card draws up to 320W under load.

Pros
  • 16GB of GDDR6X VRAM running at 23000 MHz effective speed with 736.3 GB/s bandwidth provides substantial memory throughput for demanding rendering and compute tasks
  • 52.22 TFLOPS of floating-point performance paired with 10240 shading units and 320 TMUs reflects a high-end specification for this GPU tier
  • Two HDMI 2.1a ports allow simultaneous connection of multiple HDMI displays without requiring adapters
  • ECC memory support adds data integrity assurance for users running precision-sensitive compute workloads
  • Ray tracing, DLSS, and DirectX 12 Ultimate are all supported, covering the full range of current-generation rendering features
  • Intel Resizable BAR is included, enabling the CPU to access the full GPU frame buffer more efficiently
Cons
  • A 320W TDP places significant demands on system power delivery and requires adequate PSU headroom and case airflow
  • No USB-C output is available, limiting direct connectivity for monitors or devices that use that interface
  • Air-water hybrid cooling is not supported, confining thermal management entirely to the card's air-only cooler
  • At 322mm in length, the card requires careful case clearance planning and may not fit in smaller or mid-tower enclosures with limited GPU space
  • Only two DisplayPort outputs are provided, which may limit flexibility for users who prefer to run multiple DisplayPort-connected displays
Who is this for?

The MSI GeForce RTX 4080 Super Gaming Slim is well-suited to users who need a high-throughput graphics card with 52.22 TFLOPS of floating-point performance and 16GB of GDDR6X VRAM at 736.3 GB/s bandwidth, making it a capable choice for demanding rendering, GPU compute, and workloads that benefit from large, fast memory. The support for ray tracing, DLSS, and DirectX 12 Ultimate makes it a strong fit for users engaged in modern real-time graphics pipelines, while ECC memory support extends its relevance to users with precision-sensitive compute tasks. Those who need to connect two HDMI 2.1a displays simultaneously will also benefit from the dual HDMI output configuration, which is less common among cards at this tier.

Who is this NOT for?

Users building into compact or smaller mid-tower cases will likely find the 322mm card length a genuine fitment challenge, and the absence of air-water hybrid cooling means there is no flexibility to upgrade thermal management beyond the built-in air cooler. The 320W TDP places considerable demands on system power delivery, making this card a poor fit for systems with modest PSUs or limited case airflow. Additionally, users who rely on USB-C display connectivity or need more than two DisplayPort outputs will find those options missing from this card's port layout.

number of transistors 45900 million
Has air-water cooling
width 322 mm
height 136 mm

The MSI GeForce RTX 4080 Super Gaming Slim is built on the Ada Lovelace architecture, fabricated on a 5nm process with 45,900 million transistors, and connects via PCIe 4.0. It carries a 320W TDP, which places meaningful demands on system power delivery, and relies solely on air cooling as no air-water hybrid cooling option is available. The card measures 322mm in length and 136mm in height, a footprint that warrants careful case clearance checks prior to installation.

Final Verdict

The MSI GeForce RTX 4080 Super Gaming Slim brings together a compelling high-end specification sheet, anchored by 52.22 TFLOPS of floating-point performance and 16GB of GDDR6X VRAM with 736.3 GB/s bandwidth, making it a well-equipped card for users with demanding graphics and compute workloads. Its full support for ray tracing, DLSS, DirectX 12 Ultimate, and dual HDMI 2.1a outputs adds practical versatility across rendering and multi-display scenarios. That said, its 320W power draw, 322mm length, and air-only cooling are real system requirements that need to be factored into any build plan. For users who can accommodate those constraints, the MSI GeForce RTX 4080 Super Gaming Slim stands as a technically thorough option with the memory capacity and processing throughput to handle workloads at the upper end of the graphics card category.
