Asus ProArt GeForce RTX 4070

Manufacturer: Asus

The Asus ProArt GeForce RTX 4070 is a graphics card designed around Nvidia's Ada Lovelace architecture, targeting users who need reliable rendering performance within a measured power envelope. Built on a 5nm semiconductor process, it carries 29.15 TFLOPS of floating-point performance and operates with a base clock of 1920 MHz, boosting up to 2475 MHz under load. The card measures 300mm in length and 120mm in height, fitting within a range of mid-to-full-tower chassis.

On the memory side, the card uses 12GB of GDDR6X across a 192-bit bus, reaching an effective speed of 21000 MHz and a peak bandwidth of 504.2 GB/s. It supports ECC memory and Intel Resizable BAR. The 5888 shading units are accompanied by 184 texture mapping units and 64 ROPs, yielding a texture rate of 455.4 GTexels/s and a pixel rate of 158.4 GPixels/s. Display output options include one HDMI 2.1 port and three DisplayPort connections, supporting up to four displays simultaneously. Feature support extends to DirectX 12 Ultimate, OpenGL 4.6, ray tracing, and DLSS, while OpenCL 3 compatibility is also present.

Pros
  • Supports up to four simultaneous displays, offering flexible multi-monitor setups
  • Includes ECC memory support, which helps maintain data integrity in compute-intensive workloads
  • HDMI 2.1 output alongside three DisplayPort connections provides broad compatibility with modern displays
  • Double Precision Floating Point (DPFP) support extends usability beyond standard graphics tasks into compute workloads
  • Hardware ray tracing and DLSS support are both present, enabling a wider range of rendering capabilities
  • Intel Resizable BAR support allows the CPU to access the full VRAM pool, which can benefit rendering throughput
Cons
  • Multi-GPU is not supported, limiting scaling options for users who require additional rendering capacity
  • No USB-C output is available, which may be restrictive for users with USB-C monitors or devices
  • Cooling is limited to air only, with no water-cooling option available
  • The 192-bit memory bus width is narrower than what some workstation-class cards in this category offer
  • No RGB lighting is present, which may matter to users building visually themed systems
Who is this for?

This card is well-suited to users engaged in 3D rendering, visualization, and compute workloads, given its DPFP support, ECC memory, and 12GB of GDDR6X VRAM across a 192-bit bus. The Ada Lovelace architecture with hardware ray tracing and DLSS support also makes it a reasonable fit for users working in real-time rendering pipelines or content creation environments that benefit from accelerated shading. Additionally, those running multi-display setups of up to four screens will find the port selection — three DisplayPort and one HDMI 2.1 — practical for productivity-focused configurations.

Who is this NOT for?

Users requiring multi-GPU configurations for scaling rendering or compute tasks will find this card unsuitable, as that capability is entirely absent. The 192-bit memory bus and 12GB VRAM ceiling may also fall short for workloads that demand high-bandwidth memory throughput at the top end of professional GPU use cases, such as training large machine learning models or handling very high-resolution texture assets at scale. Furthermore, users with water-cooled builds or those needing a USB-C display connection will need to look elsewhere, as neither option is available on this card.
