The 3DMark XeSS (Xe Super Sampling) feature test compares traditional TAA (Temporal Anti-Aliasing) with Intel’s XeSS upscaling technology. This test provides insight into how well a graphics card can enhance image quality while also improving performance when using AI-driven upscaling techniques as opposed to standard anti-aliasing methods.

For the ASRock Arc A770 16GB:

  1. With TAA: When using TAA, the card achieved 14.02 frames per second (FPS). This framerate reflects the demanding nature of TAA, which can provide good image quality by reducing the aliasing effect but often at the cost of performance, especially in complex scenes with ray tracing.
  2. With XeSS: After enabling XeSS, the framerate significantly increased to 43.33 FPS. This represents a performance improvement of approximately 194.7% over TAA. XeSS is designed to intelligently upscale images from a lower resolution, which means it can render frames at a lower computational cost and then upscale them to the target resolution with AI processing to enhance image details and maintain quality.

The substantial increase in framerate demonstrates the effectiveness of XeSS at boosting performance while still delivering high-quality visuals. It’s particularly noteworthy that such technologies allow for better ray tracing performance, which is traditionally very resource-intensive. This performance leap highlights the potential of AI-driven upscaling technologies like XeSS to enable higher framerates without compromising on visual fidelity, making advanced graphics features more accessible on hardware that might otherwise struggle with such demanding tasks.

ASRock Arc A770 Phantom Gaming D 16GB OC – Performance Test of 4 E-Sports Games

The ASRock Arc A770 16GB graphics card has been tested on four popular esports titles at high settings and 1440p resolution, achieving impressive frame rates that indicate excellent performance for competitive gaming:

  1. “CS2: Force 2” (likely Counter-Strike): The card delivered an average of 120 FPS. This performance level is well above the 60 FPS standard for smooth gameplay, providing a competitive edge with smooth rendering for fast-paced action.
  2. “APEX Legends”: With an average of 161 FPS, the A770 16GB offers a fluid and responsive experience, which is critical for this fast-paced battle royale game, where quick reflexes and sharp visuals can make a significant difference.
  3. “League of Legends”: Averaging 525 FPS is well beyond what’s required for this title, which isn’t as graphically demanding as other games. The A770 provides headroom for maximum settings and ensures that even in the most chaotic team fights, the action remains crystal clear and without any lag.
  4. “Rainbow Six: Siege”: An average of 244 FPS is excellent, especially considering that “Rainbow Six: Siege” is a game where precision and quick reaction times are crucial. High frame rates contribute to a smoother experience, reducing motion blur and input lag.

These results demonstrate that the Arc A770 16GB can easily handle the demands of competitive esports titles at 2K resolution, providing gamers with the high frame rates necessary for an enjoyable and competitive gaming experience. For players who prioritize frame rate and responsiveness to gain a competitive advantage, this card appears to be a solid choice, offering high performance in a range of well-loved esports games.

ASRock Arc A770 Phantom Gaming D 16GB OC – 9 games performance test

The ASRock Arc A770 16GB graphics card has been benchmarked on a suite of nine demanding AAA games at 1440p resolution with all settings maxed out, revealing its performance across a variety of gaming genres:

  1. Average Performance Across Nine Games: With an average of 76.12 FPS across all tested titles, the card demonstrates a strong capability to handle modern, graphically-intensive games at a high resolution, providing an enjoyable and smooth gaming experience.
  2. “Starry Sky” (Title unspecified, could refer to a space-themed game): Achieving 37 FPS on average, which suggests that this particular game is quite demanding or perhaps not fully optimized. The use of FSR2 (FidelityFX Super Resolution 2.0) by default is an attempt to boost frame rates without compromising too much on visual quality.
  3. “Diablo IV”: With an average of 94 FPS, this indicates that the card handles the game very well, providing more than enough performance headroom for a smooth gaming experience in this action RPG.
  4. “Red Dead Redemption 2”: Averaging 64.3 FPS is a solid performance, especially for such a demanding game known for its extensive graphics settings and detailed open world.
  5. “God of War”: The average of 48 FPS indicates that this highly detailed and visually impressive title is pushing the boundaries of what the card can do at ultra settings in 1440p. However, it remains close to that smooth 60 FPS mark, which can likely be achieved by enabling FSR to upscale from a lower resolution.

The mention of FSR technology for “Starry Sky” and “God of War” is noteworthy. FSR, or FidelityFX Super Resolution, is AMD’s upscaling technology that aims to increase frame rates by rendering games at a lower resolution and then upscaling them to the target resolution, enhancing performance without significantly degrading visual quality. When games are particularly performance-heavy, technologies like FSR can be very beneficial in maintaining higher frame rates while still providing an immersive gaming experience.

Overall, these results illustrate that the ASRock Arc A770 16GB is quite capable of running the latest AAA titles at 1440p, with most games running comfortably above 60 FPS. For the most demanding titles, tweaking settings or leveraging upscaling technologies can provide a more fluid experience.

ASRock Arc A770 Phantom Gaming D 16GB OC – 7 ray tracing DXR game tests

The ASRock Arc A770 16GB GPU has undergone performance testing with seven ray tracing-capable games, showcasing how it handles some of the most graphically demanding scenarios at 1440p resolution:

  1. Overall Ray Tracing Performance: The average frame rate across these seven ray tracing-enabled titles was 112.4 FPS, which at first glance seems quite impressive. However, this average may be skewed by some titles performing exceptionally well, which can elevate the overall figure.
  2. “Star Wars Jedi: Survivor”: With only 30 FPS even after FSR2 (FidelityFX Super Resolution 2.0) acceleration, it’s clear that the intense demands of ray tracing at high resolutions are pushing the GPU to its limits. For more fluid gameplay, players may need to compromise on either resolution or graphical settings.
  3. “Spider-Man: Miles Morales”: The card fares better in this title, with XeSS (Intel’s Xe Super Sampling technology) acceleration boosting performance to an average of 84 FPS, suggesting a more balanced combination of visual fidelity and frame rate.
  4. “The Witcher 3: Wild Hunt”: With XeSS acceleration, the average frame rate is around 50 FPS. Considering the age of the game, this performance indicates that the implementation of ray tracing and upscaling technologies still demands significant GPU power.

The information provided reflects that while the ASRock Arc A770 16GB is capable of ray tracing, achieving stable and high performance in the most demanding titles with all the visual effects turned on can be a challenge. It appears that in games with heavy ray tracing loads, the current iteration of XeSS, while helpful, is not sufficient to maintain high frame rates without some compromises.

For gamers aiming for smoother gameplay in these titles, lowering some graphical settings may be necessary. This adjustment would balance the visual enhancements that ray tracing provides with the need for a fluid gaming experience, especially in action-packed scenes where higher frame rates are crucial for responsiveness.

ASRock Arc A770 Phantom Gaming D 16GB OC Power Consumption and Temperature
