ARCHITECTURE

NVIDIA has introduced the Blackwell architecture as a new technology standard for graphics processing units. This solution marks a significant leap in computer graphics and computing, offering an unrivaled combination of performance, power efficiency, and advanced technologies. Blackwell is designed to support modern gaming and professional workloads such as ray tracing, real-time rendering, and deep learning.

The key difference of the new architecture is a redesigned approach to processing graphic data. The new generation of streaming multiprocessors provides the highest throughput, which allows minimizing delays and accelerating work with highly loaded processes. New computing units optimized for neural shaders have become the basis for working with advanced graphic engines and artificial intelligence algorithms.

RTX Blackwell SM

Blackwell is introducing the fifth generation of Tensor Cores, which have become significantly more efficient at performing machine learning tasks. They support formats such as FP4, which opens up new possibilities for processing large data sets. This is especially important for rendering complex scenes, generating textures, and improving the visual component in games.

The fourth-generation ray tracing cores deliver greater precision and performance when working with global illumination technology, allowing you to create scenes with the highest level of realism, where reflections, shadows, and refractions look as if they were captured on camera.

5080

The GeForce RTX 5080 is a powerful graphics processor designed for professionals and gamers. The graphics card includes 10 CUDA cores, which allows it to handle the most resource-intensive tasks. The power consumption of the device is 752 W, which requires a power supply unit with a capacity of at least 360 W.

The graphics card comes with 16GB of GDDR7 memory with a bandwidth of up to 960GB/s. This provides incredible data transfer speeds, which is especially noticeable when working with games at 4K and 8K resolutions. The RTX 5080 also supports a clock speed of up to 2,62GHz in Boost mode, making it one of the fastest on the market.

The cooling technology has been completely redesigned to manage the increased power of the graphics processor. The use of new temperature controllers and an active cooling system allows you to maintain stable operation of the device even under extreme loads.

The GeForce RTX 5080 brings a host of innovative technologies to the industry that raise the bar for quality in computer graphics. One of the biggest advances is the introduction of DLSS 4, which significantly improves the visuals of games. The new version uses multi-frame generation to create additional frames, resulting in higher frame rates without significantly increasing the load on the GPU.

RTX Blackwell GB202 Fullchip

Reflex 2 technology minimizes input lag, making it ideal for competitive gaming. The new NVIDIA Encoder improves video recording and streaming quality, adding support for resolutions up to 8K.

The RTX 5080 also gains support for full real-time ray tracing rendering, allowing for more complex scenes that achieve realism through accurate simulation of lighting, shadows, and textures.

The graphics card is aimed not only at gamers, but also at content creators. The NVIDIA Studio platform provides advanced tools for video editing, 3D modeling, and graphic design. RTX 5080 opens up new possibilities for professionals working in the field of visualization and animation.

OPERATING MODES GPU Tweak III
 
Asus ROG Astral GeForce RTX 5080 OC – High-Performance Graphics Card Fully Compatible with the Utility GPU Tweak III, which provides advanced features for monitoring, configuring and overclocking the graphics processor. The new version of the program features an intuitive interface, improved VF Tuner functionality for precise overclocking and automatic profile switching.

Three modes of operation of Asus ROG Astral GeForce RTX 5080 OC

Depending on the user's preferences, the video card supports several operating modes:

1

  • Default Mode
    Under standard conditions, the frequency GPU Boost reaches 2760 MHz, and the Power Target is set to 100%. This mode is balanced between performance and power consumption.

2

  • Overclocking Mode (OC Mode)
    This mode increases the power limit to 110% and raises the clock speed to 2780 MHz. This allows you to squeeze the maximum out of the GPU, allowing for higher operating frequencies.

3

  • Silent Mode
    In Silent mode, the verlimit is reduced to 90%, and the frequency GPU Boost is 2740 MHz. This reduces power consumption and noise levels while maintaining high performance.

Additional features

  • Temperature control – in various modes, operating temperatures remain at a comfortable level (from 30 to 32°C).
  • 0dB Fan Technology – fans remain off at low load.
  • Support 12VHPWR – stable power supply and overload protection.

Asus ROG Astral GeForce RTX 5080 OC is a powerful and flexible graphics card that can be adapted to various usage scenarios, from maximum overclocking to quiet operation with low power consumption.

В Cyberpunk 2077 The Asus ROG Astral GeForce RTX 5080 OC delivers outstanding performance thanks to the 4th generation frame generator (MFG). At 2560x1440 the video card in standard mode produces 40 FPS, but with MFG technology enabled the frame rate rises to 144, significantly outpacing RTX 4090, which has only a second-generation frame generator and a maximum result of 87 FPS.

At 4K resolution, the difference remains: the RTX 5080 OC without MFG shows 21 FPS, but with the 4th generation of the generator, the frame rate increases to 75. RTX 4090 with the second generation FG enabled, the figure only reaches 45 FPS.

CONCLUSION

Asus ROG Astral GeForce RTX 5080 OC demonstrates excellent performance in all modern games, approaching the level RTX 4090, but with more efficient power consumption. One of the main advantages of the card is the support of the 4th generation frame generator (MFG), which significantly increases FPS in projects with scaling. Cyberpunk 2077 at 1440p with MFG the frame rate reaches 144 FPS, surpassing RTX 4090 with the second generation FG.

In resolution 2560x1440 The card consistently maintains over 100 FPS in most modern games, and in 4K the figures remain at 50–75 FPS, which ensures smooth gaming even at high settings.

The cooling works effectively - in FurMark the temperature does not exceed 64 degrees, and in gaming loads it stays around 60 degrees with power consumption up to 360 W. The cooling system copes with the load even during long sessions, ensuring stable operation.

Asus ROG Astral GeForce RTX 5080 OC is a powerful and advanced gaming solution with high energy efficiency and advanced technologies. The video card confidently handles modern projects in 1440p and 4K, providing a comfortable FPS level even in the most demanding games.
