AMD Radeon RX 7700S: A Guide to the Graphics Card for Gamers and Enthusiasts

April 2025

With the release of the Radeon RX 7700S, AMD has solidified its position in the mid-range GPU market. This card promises a balance between price, performance, and modern technologies. Let's explore who it’s suitable for and what it is capable of.

1. Architecture and Key Features

RDNA 4: A Leap in Efficiency

The RX 7700S is built on the RDNA 4 architecture, which is a natural progression from RDNA 3. Key improvements focus on energy efficiency and support for new technologies:

- Manufacturing Process: 5nm TSMC (N5P), which reduced power consumption by 15% compared to the previous generation.

- Compute Units: 32 Compute Units (CU), 2048 stream processors.

- Ray Accelerators: 32 hardware accelerators for ray tracing—20% faster than in RDNA 3.

Unique Features

- FidelityFX Super Resolution 3.5: Updated upscaling algorithm with AI-driven nets for detail enhancement and Fluid Motion Frames for smoothness.

- Hybrid Ray Tracing: A combination of hardware and software acceleration for ray tracing to reduce the load on the GPU.

- Anti-Lag+: A technology designed to minimize input lag when paired with Ryzen 7000/8000 processors.

2. Memory: Speed and Capacity

GDDR6 Optimized for 1440p

- Capacity: 12 GB GDDR6.

- Bus: 192-bit (maximum bandwidth of 432 GB/s).

- Infinity Cache: 64 MB, which reduces dependence on bus width.

For 1440p (QHD) gaming, this is sufficient: even in demanding titles like Starfield: Enhanced Edition, video memory utilization reaches 80-90%. However, for 4K at ultra settings with ray tracing, 12 GB may be at its limit.

3. Gaming Performance

FPS in Popular Titles (tests at QHD, Ultra settings):

- Cyberpunk 2077: Phantom Liberty: 68 FPS (without RT), 42 FPS (with RT + FSR 3.5).

- Call of Duty: Black Ops VI: 112 FPS (DLSS-like features turned off).

- Horizon Forbidden West PC Edition: 85 FPS.

Resolutions and Ray Tracing

- 1080p: All games run stably above 100 FPS even with ray tracing.

- 1440p: An optimal choice—balance between quality and smoothness.

- 4K: Only with FSR 3.5 and medium settings (55-60 FPS).

Ray tracing remains AMD’s weak point: the RX 7700S lags behind the NVIDIA RTX 4070 by 20-25% in RT scenarios.

4. Professional Tasks

Editing and Rendering

- Blender, DaVinci Resolve: Support for OpenCL and ROCm 5.5 ensures stable operation, but rendering speed is 30% slower than the NVIDIA RTX 4060 Ti (due to CUDA).

- 3D Modeling: In Autodesk Maya and ZBrush, the card shows minimal lag when working with polygonal scenes.

Scientific Computing

For machine learning or simulations, it’s better to choose NVIDIA (thanks to optimization for TensorFlow/PyTorch). However, ROCm 5.5 allows for work with HIP libraries, albeit with some limitations.

5. Power Consumption and Thermal Output

TDP and Recommendations

- TDP: 180W.

- Temperatures: Under load—up to 75°C (reference cooler); in custom builds (ASUS Dual, Sapphire Pulse)—65-70°C.

PC Building Tips:

- Case with 3-4 fans (at least 2 for intake, 1 for exhaust).

- Tower coolers for the CPU (to avoid overheating in compact cases).

- Power supply from 600W (recommended 650W with 80+ Bronze certification or higher).

6. Comparison with Competitors

AMD vs NVIDIA

- RX 7700S vs RTX 4060 Ti (16 GB):

- In games without RT: parity (±5%).

- With RT: NVIDIA wins by 25-30%.

- Price: RX 7700S — $399, RTX 4060 Ti — $449.

- RX 7700S vs RX 7600 XT:

- +15% performance for the RX 7700S at a $50 price difference.

Conclusion:

For gamers not focusing on RT, AMD is more affordable. For professionals and RT enthusiasts—NVIDIA.

7. Practical Advice

- Power Supply: 650W (for example, Corsair CX650M).

- Platform: Compatible with PCIe 5.0 but works on PCIe 4.0 without losses.

- Drivers: Adrenalin 2025 Edition is stable, but update manually—automatic updates sometimes reset settings.

8. Pros and Cons

Pros:

- Excellent price for performance at 1440p.

- Support for FSR 3.5 and Fluid Motion Frames.

- Quiet operation of custom models.

Cons:

- Weak RT performance.

- No hardware support for AI frame generation, unlike NVIDIA.

9. Final Conclusion: Who is the RX 7700S For?

This graphics card is the ideal choice for:

- Gamers playing in QHD without a focus on ray tracing.

- Streamers who value stability and low power consumption.

- AMD enthusiasts upgrading their systems without overpaying for top-tier models.

If you’re looking for a GPU for $400 with a lifespan of 2-3 years, the RX 7700S is one of the best options. However, for 4K or professional RT rendering, consider the NVIDIA RTX 4070 or RX 7800 XT.

Memory Bus

The memory bus width refers to the number of bits of data that the video memory can transfer within a single clock cycle. The larger the bus width, the greater the amount of data that can be transmitted instantaneously, making it one of the crucial parameters of video memory. The memory bandwidth is calculated as: Memory Bandwidth = Memory Frequency x Memory Bus Width / 8. Therefore, when the memory frequencies are similar, the memory bus width will determine the size of the memory bandwidth.

Bandwidth

Memory bandwidth refers to the data transfer rate between the graphics chip and the video memory. It is measured in bytes per second, and the formula to calculate it is: memory bandwidth = working frequency × memory bus width / 8 bits.

ROPs

The Raster Operations Pipeline (ROPs) is primarily responsible for handling lighting and reflection calculations in games, as well as managing effects like anti-aliasing (AA), high resolution, smoke, and fire. The more demanding the anti-aliasing and lighting effects in a game, the higher the performance requirements for the ROPs; otherwise, it may result in a sharp drop in frame rate.
