MSI GeForce RTX 4080 Super Gaming X Slim

Manufacturer: MSI

The MSI GeForce RTX 4080 Super Gaming X Slim is a graphics card based on NVIDIA's Ada Lovelace architecture, manufactured on a 5 nm process with 45,900 million transistors. It includes RGB lighting and relies on air cooling, with a 320W Thermal Design Power and physical dimensions of 322 mm in width and 136 mm in height.

The card's 10,240 shading units and 320 texture mapping units deliver 53.45 TFLOPS of floating-point performance, a texture rate of 835.2 GTexels/s, and a pixel rate of 292.3 GPixel/s, with the GPU boosting up to 2,610 MHz. Its 16GB of GDDR6X memory runs at an effective 23,000 MHz over a 256-bit bus, providing up to 736.3 GB/s of bandwidth with ECC support included. Feature coverage includes ray tracing, DLSS, DirectX 12 Ultimate, Intel Resizable BAR, and up to four simultaneous displays via two HDMI 2.1a ports and two DisplayPort outputs.

Pros

A boost clock of 2,610 MHz combined with 53.45 TFLOPS of floating-point throughput gives the card considerable headroom for graphics-intensive and compute-oriented tasks
16GB of GDDR6X memory on a 256-bit bus delivers 736.3 GB/s of bandwidth, supporting workloads that move large volumes of data through the memory subsystem
Ray tracing and DLSS are both supported, enabling hardware-accelerated lighting and AI-based upscaling in compatible applications
Two HDMI 2.1a ports alongside two DisplayPort outputs provide flexibility for users running multi-display configurations across different display types
ECC memory support adds reliability for GPU compute tasks where data accuracy is a requirement
RGB lighting is included, giving users the ability to integrate the card into visually themed system builds

Cons

A 320W TDP demands a well-specified power supply and adequate system airflow, which may not suit all builds
Water cooling is not supported, restricting thermal management to air cooling only regardless of the thermal environment or chassis
USB-C, DVI, and mini DisplayPort outputs are absent, limiting connectivity for users who depend on those interfaces
XeSS (XMX) upscaling is not supported, narrowing the range of available upscaling options in compatible software

Who is this for?

The MSI GeForce RTX 4080 Super Gaming X Slim is a strong fit for users who demand ray tracing and DLSS-capable rendering at a high throughput level, with 53.45 TFLOPS and a 2,610 MHz boost clock providing meaningful headroom for demanding graphics workloads. Its 16GB of GDDR6X memory with 736.3 GB/s of bandwidth, combined with ECC support and Double Precision Floating Point capability, also makes it suitable for GPU-accelerated compute tasks where both capacity and data integrity are relevant. Users who want multi-display flexibility across two HDMI 2.1a and two DisplayPort connections will find the four-output configuration practical for both productivity and gaming setups.

Who is this NOT for?

The card's 320W TDP and air-only cooling make it a poor match for systems with constrained power delivery or users planning to integrate it into a custom water-cooling loop, since no water-cooling support is available. Its 322 mm length and 136 mm height may also create clearance issues in compact or small-form-factor enclosures, ruling it out for space-limited builds. Users who rely on USB-C display outputs or XeSS upscaling will find neither supported, which could be a limitation depending on display hardware or upscaling workflow preferences.
