AMD Radeon RX 6750 GRE: A Gaming GPU for 1440p and Beyond

April 2025

Introduction

The AMD Radeon RX 6750 GRE video card carved its niche in mid-2024 as an affordable solution for comfortable gaming at 1440p resolution. Despite competition from NVIDIA and AMD's own Radeon RX 7000 lineup, this model remains relevant due to its balance of price, performance, and technologies. In this article, we will explore who this GPU is suitable for, how it performs in gaming and professional tasks, and what to pay attention to when purchasing.

Architecture and Key Features

RDNA 2: Power with an Eye on the Future

The RX 6750 GRE is built on the RDNA 2 architecture, which debuted in 2020. Despite its "age," optimizations have kept it competitive. The chip is manufactured using a 7nm process (TSMC N7), which provides a balance between energy efficiency and performance.

Unique Features

- Ray Accelerators: Hardware blocks for ray tracing. Compared to RDNA 3, the ray processing speed is lower, but for a mid-range card, the results are respectable.

- FidelityFX Super Resolution (FSR): Support for FSR 3.0 with Fluid Motion Frames technology, which increases FPS through frame interpolation.

- Radeon Anti-Lag+: Reduces input lag in competitive games (CS2, Valorant).

Lack of DLSS 3 equivalents: Unlike NVIDIA with its DLSS 3.5 (featuring neural network upscaling), AMD relies on FSR, which works on any GPU but requires more resources for comparable quality.

Memory: Fast but Not Maximum

GDDR6 and 12 GB - The Optimal Choice

The card is equipped with 12 GB of GDDR6 memory with a 192-bit bus. The bandwidth reaches 432 GB/s (16 Gbps effective speed). For comparison, the NVIDIA RTX 4060 Ti (128-bit, 288 GB/s) falls short in this aspect, making the RX 6750 GRE more advantageous for games with heavy textures.

Why not GDDR6X?

The use of GDDR6 instead of GDDR6X lowers production costs and heat, which is crucial for models priced below $400. In games like Cyberpunk 2077 or Hogwarts Legacy, 12 GB of memory prevents FPS drops at ultra settings in 1440p.

Gaming Performance: 1440p as a Comfortable Zone

Average FPS in Popular Titles (without FSR):

- Cyberpunk 2077 (Ultra): 58 FPS (1440p), 32 FPS with ray tracing.

- Call of Duty: Modern Warfare III (Extreme): 92 FPS (1440p).

- Alan Wake 2 (High): 45 FPS (1440p), but with FSR 3.0 Quality — up to 75 FPS.

- Fortnite (Epic, DX12): 114 FPS (1440p).

Ray Tracing: Moderate Ambitions

Enabling RT reduces FPS by 35-50%, but with FSR 3.0, the card handles games at 1080p (for example, Cyberpunk 2077 — 55 FPS with RT Medium + FSR Quality). For full RT in 1440p, it’s better to look at the Radeon RX 7800 XT or NVIDIA RTX 4070.

Professional Tasks: Not Just Gaming

Video Editing and Rendering

- DaVinci Resolve: Accelerated encoding H.264/H.265 through AMD Media Engine.

- Blender: HIP support is available, but rendering speed is 1.5-2 times slower than the NVIDIA RTX 4060 Ti (due to CUDA optimization).

3D Modeling

In Maya and ZBrush, the card shows stability, but for complex scenes with RTX rendering (Octane, V-Ray), NVIDIA is preferable.

Scientific Calculations

OpenCL performance is adequate for basic-level machine learning, but ROCm (AMD's computing platform) is not supported by all frameworks.

Conclusion: The RX 6750 GRE is suitable for video editing and light 3D creativity, but it won't replace professional solutions.

Power Consumption and Thermal Management

TDP 250W: Requires Thoughtful Cooling

Recommended power supplies start at 650W (for a system with a Ryzen 5 7600X). Reference models and dual-fan versions (ASUS Dual, Sapphire Pulse) heat up to 75-80°C under load. High-end custom solutions (PowerColor Red Devil) lower temperatures to 65-70°C.

Case Recommendations:

- Minimum of 3 case fans (2 intake, 1 exhaust).

- Avoid compact cases (like NZXT H210) — limited airflow increases temperatures by 5-7°C.

Comparison with Competitors

Within the AMD Family:

- RX 7600 XT ($330): A lower model with 8 GB GDDR6. Underperforms in 1440p by 20-25%.

- RX 7700 ($450): Newer but more expensive. Performance boost is 15-20%.

NVIDIA:

- RTX 4060 Ti 16GB ($400): Better in RT and supports DLSS 3.5, but the narrow memory bus (128-bit) limits performance in 1440p.

- RTX 3070 (used ~$300): Comparable raw performance, but lacks access to DLSS 3.5 and has only 8 GB of memory.

Conclusion: The RX 6750 GRE outperforms competitors under $400, offering more memory and stability in 1440p.

Practical Tips

Power Supply: Don't skimp! It's better to get a 650-750W PSU with an 80+ Gold certification (Corsair RM650x, be quiet! Straight Power 11).

Compatibility:

- PCIe 4.0 x16 is essential for full performance.

- Motherboards on AMD B550/X570 or Intel B660/Z790.

Drivers:

- Adrenalin Edition 2025 is stable, but disable "Instant Replay" while streaming — it puts extra load on the GPU.

- For professional tasks, use PRO drivers (more stable in OpenCL).

Pros and Cons

Pros:

- Best price-performance ratio under $400 for 1440p.

- 12 GB of memory "future-proof".

- Good support for FSR 3.0.

Cons:

- High power consumption.

- Weak ray tracing performance.

- Lack of hardware optimization for AI tools.

Final Conclusion: Who is the RX 6750 GRE Suitable For?

This graphics card is the ideal choice for:

1. Gamers who want to play at 1440p on high settings without ray tracing.

2. Streamers who value stability and AV1 support in OBS.

3. Enthusiasts on a budget planning an upgrade in 2-3 years.

At its current price of $379 (new models, April 2025), the RX 6750 GRE remains a "golden mean," offering maximum capabilities for its price. However, if ray tracing or AI features are critical to you, it may be worth paying extra for the NVIDIA RTX 4070 or Radeon RX 7800 XT. But for everyone else — this is the optimal choice.

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.

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.
