AMD Radeon RX 6750 GRE 12 GB: Review and Analysis for Gamers and Professionals

April 2025

1. Architecture and Key Features

RDNA 3: A Balance of Efficiency and Power

The AMD Radeon RX 6750 GRE 12 GB graphics card is built on the updated RDNA 3 architecture, which represents an evolution of the Radeon RX 6000 series. Key improvements focus on energy efficiency and support for modern technologies. The chips are manufactured using TSMC's 6nm process technology, which reduces heat generation without sacrificing performance.

Unique Features

- FidelityFX Super Resolution (FSR 3.0): AMD's upscaling technology, which in version 3.0 adds frame generation, enhancing FPS in ray-tracing supported games.

- Ray Accelerators: Hardware blocks for accelerating ray tracing. The RX 6750 GRE has 40 of these, which is 10% more than the RX 6700 XT.

- Smart Access Memory (SAM): Optimization of the interaction between CPU and GPU for performance gains of up to 15% when paired with Ryzen 5000/7000 processors.

2. Memory

GDDR6 and 12 GB: Future-Proof Capacity

The card is equipped with 12 GB of GDDR6 memory with a 192-bit bus. The bandwidth reaches 432 GB/s (memory frequency — 18 Gbps). This is sufficient for comfortable gaming at 1440p and working with high-resolution textures.

Why 12 GB?

- Modern games like Cyberpunk 2077: Phantom Liberty or Avatar: Frontiers of Pandora consume up to 10-11 GB of VRAM at 1440p.

- For professional tasks (rendering 3D scenes), the memory capacity minimizes the need to swap data from the RAM.

3. Gaming Performance

FPS in Popular Titles (1440p, Ultra Settings)

- Cyberpunk 2077 (without RT): 78 FPS (with FSR 3.0 — up to 110 FPS).

- Hogwarts Legacy: 65 FPS, with RT on medium — 48 FPS.

- Call of Duty: Modern Warfare III: 120 FPS.

Resolution Support

- 1080p: Maximum settings in any game.

- 1440p: Optimal choice for 144 Hz monitors.

- 4K: Requires reduced settings or activation of FSR 3.0 (average FPS — 40-50 in AAA titles).

Ray Tracing

The RX 6750 GRE handles RT at medium settings, but falls short compared to the NVIDIA RTX 4070. For instance, in Alan Wake 2 with RT High and FSR 3.0, the card achieves 55 FPS, compared to 72 FPS for the RTX 4070.

4. Professional Applications

Video Editing and 3D Rendering

With support for OpenCL and Vulkan, the card is suitable for:

- Editing in DaVinci Resolve: rendering a 4K project in 12-15 minutes.

- 3D modeling in Blender: rendering a medium-level scene in 8-10 minutes (compared to 6-7 minutes for the RTX 4060 Ti).

Scientific Calculations

- ROCm (AMD's equivalent to CUDA) provides compatibility with machine learning, but libraries are less optimized compared to NVIDIA's.

5. Power Consumption and Thermal Output

TDP and Recommendations

- The card's TDP is 230 W. A 650 W power supply (e.g., Corsair RM650x) is required for stable performance.

- Cooling systems:

- Reference models use 2-3 fans. Temperature under load reaches up to 75°C.

- Custom solutions (Sapphire Nitro+, ASUS TUF Gaming) reduce temperatures to 65-70°C.

Case Tips

- Minimum case size: Mid-Tower with 3 PCIe slots.

- Adequate ventilation is essential: 2 intake fans at the front, 1 exhaust fan at the back.

6. Comparison with Competitors

AMD vs NVIDIA vs Intel

- NVIDIA RTX 4060 Ti 16 GB ($450): Better at RT (+30%) and supports DLSS 3.5, but is more expensive.

- Intel Arc A770 16 GB ($320): Weaker in DX11 games, but cheaper.

- AMD RX 7700 XT ($400): 15% more performance, but $50 more expensive.

Conclusion: The RX 6750 GRE ($350-370) is the optimal choice for those who value memory size and price.

7. Practical Tips

Power Supply

- Minimum: 650 W with an 80+ Bronze certification.

- Recommended models: Seasonic Focus GX-650, Be Quiet! Pure Power 12 M.

Compatibility

- PCIe 4.0 x16. Motherboard support: AMD AM4/AM5, Intel LGA 1700.

- To activate SAM, a Ryzen 5000/7000 processor and a motherboard with UEFI based on AGESA 1.2.0.7+ are needed.

Drivers

- Adrenalin Edition 2025 is stable, but use the AMD WattMan tool for fine-tuning during overclocking.

8. Pros and Cons

Pros:

- Excellent price for 12 GB of memory.

- Support for FSR 3.0 and frame generation.

- Energy efficiency is better than the previous generation.

Cons:

- Ray tracing performance is weaker than NVIDIA's offerings.

- Limited optimization for professional tasks (CUDA vs OpenCL).

9. Final Conclusion

Who is the RX 6750 GRE Suitable For?

- Gamers who want to play at 1440p without compromises.

- Enthusiasts with a budget of up to $400 who value VRAM capacity.

- Content creators working in programs that support OpenCL.

Why this card?

At $350, it is one of the best cards in its segment, offering a balance between price, performance, and future relevance over the next 2-3 years. If ray tracing is not a priority for you, the RX 6750 GRE will be a reliable 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.

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.
