MSI GeForce RTX 4080 Super Gaming X Slim White

Manufacturer: MSI

The MSI GeForce RTX 4080 Super Gaming X Slim White is a graphics card based on NVIDIA's Ada Lovelace architecture, manufactured on a 5 nm process and housing 45,900 million transistors. It operates at a base clock of 2295 MHz, reaching a turbo frequency of 2610 MHz, and carries an RGB lighting setup along with support for up to four simultaneous displays. The card measures 322 mm in length and 136 mm in height, and draws up to 320W as specified by its thermal design power rating.

On the memory side, the card is equipped with 16GB of GDDR6X across a 256-bit bus, delivering an effective memory speed of 23,000 MHz and a peak bandwidth of 736.3 GB/s. Its 10,240 shading units, 320 texture mapping units, and 112 render output units contribute to a texture rate of 835.2 GTexels/s and a floating-point throughput of 53.45 TFLOPS. Feature support includes DirectX 12 Ultimate, OpenGL 4.6, OpenCL 3, ray tracing, DLSS, Intel Resizable BAR, and ECC memory, with connectivity provided through two HDMI 2.1a ports and two DisplayPort outputs.

Pros
  • The 16GB of GDDR6X memory running across a 256-bit bus delivers 736.3 GB/s of bandwidth, giving the card substantial headroom for memory-intensive workloads
  • With 10,240 shading units, 320 texture mapping units, and 112 ROPs, the card offers a dense compute configuration suited to demanding rendering tasks
  • Support for ray tracing and DLSS together allows for more realistic lighting in compatible titles alongside AI-assisted frame generation
  • Up to four displays can be connected simultaneously using the two HDMI 2.1a and two DisplayPort outputs, offering flexible multi-monitor setups
  • ECC memory support adds a layer of error correction that benefits users running precision-sensitive or professional GPU workloads
  • Intel Resizable BAR support allows the CPU broader access to GPU memory, which can reduce data transfer bottlenecks during rendering
Cons
  • A 320W TDP places significant demands on system power delivery and cooling infrastructure, requiring a capable PSU and well-ventilated case
  • At 322 mm in length and 136 mm in height, the card occupies considerable physical space and may not fit in compact or mid-tower enclosures
  • There are no USB-C, DVI, or mini DisplayPort outputs, which limits compatibility with certain monitors or adapters without additional hardware
  • Air-water cooling is not included, meaning users relying on liquid cooling solutions will need to source third-party options separately
  • XeSS (XMX) is not supported, restricting access to that particular upscaling technology for users who may prefer it
Who is this for?

This card is well-suited to users running demanding rendering and compute workloads that benefit from 16GB of GDDR6X memory, high bandwidth, and ECC memory support for error-sensitive tasks. It also fits those building high-output workstations or gaming setups that take advantage of ray tracing, DLSS, and multi-display support across up to four screens simultaneously. The inclusion of Intel Resizable BAR and a dense shader configuration makes it a practical choice for users who need consistent throughput across both graphics and general-purpose GPU tasks.

Who is this NOT for?

Users working within compact or small form factor builds will likely find the 322 mm length and 136 mm height too large to accommodate without significant case constraints. The 320W TDP also makes this card a poor fit for systems with modest power supplies or limited airflow, as it places considerable strain on both the PSU and chassis cooling. Additionally, users whose workflows or display setups depend on USB-C output or liquid cooling integration will find this card lacking in those specific areas.
