amazon Gigabyte GV-R797TO-3GD reviews
Compared to the “GV-R797OC-3GD”, the new card, based on the AMD Radeon HD 7970 GHz Edition GPU, has a more powerful graphics processor, higher memory clock, and power consumption quite.
Design
The Gigabyte GV-R797TO-3GD is based on the new AMD Radeon HD 7970 GHz Edition graphics processor (codenamed Tahiti XT2) with the new Graphics Core Graphics (GCN) architecture to better utilize multiple pipeline processing capabilities. GPU graphics at the same time and does not significantly affect overall performance. In addition, the card is equipped with 3GB GDDR5 memory, 1.500MHz clock and 384 bit memory interface.
Similar to the GV-R797OC-3GD, the new graphics card GV-R797TO-3GD has been overclocked by the manufacturer, so the GPU operates at a default clock frequency of up to 1,100MHz; About 10% higher than the standard Tahiti XT2 (1,000MHz) and the power consumption of the card is also higher. As recommended by Gigabyte, readers should choose 600W or more power supply to ensure power to meet the entire system.The block diagram above shows that the Radeon HD 7970 GHz Edition (HD 7970GE) GPU also includes 32 compute units with 2,048 stream processing units, 128 texture unit and 32 Color ROP Unit.
In terms of size, the Gigabyte GV-R797TO-3GD is “full size” (285x38x126mm) and weighs about 780g. The Triangle Cool cooling system incorporates three 80mm (WindForce 3x) cooling fans to ensure optimum heat dissipation as well as minimizing background noise during operation. The test results below show that the cooling system is efficient, the highest GPU temperature is 66 degrees Celsius at maximum load, the fan is quiet and has a negligible impact on the surrounding environment.
Technology, support features
In addition to the support technologies and features that AMD integrates in the Graphics Core Next generation graphics architecture, the full support for the DirectX 11 graphics library, OpenGL 4.2, Shader Model 5.0. Enhanced Quality Anti-Aliasing (EQAA) and Morphological Anti-Aliasing (MLAA) feature improve image quality during and after framing or support image resolution up to 4096×2160 (4K support).
The GV-R797TO-3GD is also equipped with Ultra Durable VGA (UDV) technology; Similar to the Ultra Durable that the company applied on BMC to improve card stability when operating continuously for a long time. According to Gigabyte, the application of UDV technology along with the WindForce 3x heatsink reduces the card’s temperature by about 15% compared to previous generations of graphics cards.
Performance evaluation
Test Lab is still using tests including 3DMark 11, Heaven Benchmark v3.0 and some DirectX 11 games like DiRT 3, Alien Vs. Predator 1.03 and Crysis 2 run at 1280×720 (HD 720p) and 1920×1080 (full HD 1080p) to evaluate the power of the GV-R797TO-3GD. Test configuration builds on the Z77 BMC chipset, Windows 7 Ultimate 64 bit SP1 and Catalyst 12.8 driver.
In tests of multi-thread processing of the processor and graphics card based on the tool 3DMark 11. In Performance mode, GV-R797TO-3GD reached 9,111 points 3DMark 11 and 9,021 points GPU. Similarly in Extreme mode, test configuration reached 3,145 points 3DMark 11 and 2,857 GPU points; About 10% higher than the GV-R797OC-3GD (Radeon HD 7970). Compared with the GV-N680OC-2GD, the GeForce GTX 680 GPU graphics card, the card scores are still 9.76 – 10.93% lower in the same test.
Surprisingly, the GV-R797TO-3GD went beyond the benchmark GV-N680OC-2GD in the Heaven Benchmark; The graphics test is pretty much similar to 3DMark 11 but mainly emphasizes tessellation technology.
Specifically, the GV-R797TO-3GD fps reaches 48.1 fps at 1080p full HD resolution and the highest graphics quality (tessellation: extreme, shaders: high, 8xAA and 16xAF), 60.33% higher than “benchmark” 30fps and 17.89% higher than GV-N680OC-2GD.
Similar to DirectX 11 games under the Test Lab scenario built at 1920×1080 (full HD) resolution, graphics quality is boosted to the highest level with 8x antialiasing modes (8xAA), unmatched filtering 16xAF, more detailed image display, etc. GV-R797TO-3GD is significantly higher in most frames per second than the GV-R797OC-3GD.
With the DiRT 3, the GV-R797TO-3GD gets 261.9fps at 720p HD resolution and the lowest is 110.5fps at 1080p full HD resolution, with Ultra graphics quality.
With Alien vs. Predator, the GV-R797TO-3GD has 263.2fps at 720p resolution and the lowest is 76.6fps at 1080p full HD resolution, Very High graphics quality; Higher than the GV-N680OC-2GD were respectively 47.12%, 71.18% and 69.84% in the same test.
With Crytek’s Crysis 2 – a monument in the FPS genre, the test results of the card at full HD resolution, Extreme graphics quality still doubles that of the standard 30 fps benchmark. Also about 12.97% higher than GV-N680OC-2GD.

Temperature, power consumption
To test the graphics card heat dissipation and the power consumption of the test configuration (not including the monitor), Test Lab uses the MSI Afterburner utility with graphical emulation “heavy-duty” MSI Kombustor with the library DirectX 11. The system temperature and power were recorded using GPU-z and Logger Lite software in a 26°C environment.
In no-load mode, the GPU temperature fluctuates at 32 degrees Celsius, the fan operates very smoothly at a speed of 1,190 rpm. The power consumption of the test configuration is 62.6W, calculated by means of averages.
With the MSI Kombustor graphics test, the GPU temperature is up to 66 degrees Celsius, the fan remains quiet at 3.150 rpm while the test power consumption of the test configuration reaches 303 watts, calculated in the highest value.
Still using the MSI Kombustor graphics test and pushing the fan speed to the highest (4,600rpm), the GPU temperature dropped to 59 degrees Celsius (18.8% lower) but compensated for the fan noise is very high, photo Significantly affect the surrounding environment. The power consumption of the test configuration also reached 324W; calculated in the highest value.
Comment
AMD’s new Radeon HD 7970GE (Tahiti XT2) graphics processor with more graphics processing power, clocking and higher memory bandwidth delivers a new level of power to the most advanced monochrome GPUs. In addition, refining the AMD Catalys drivers (some recent versions) has also contributed to improving the number of display frames in the game; Also included in the games is supposed to be better support for graphics cards equipped with NVIDIA GPUs. However, the processing power of the Radeon HD 7970GE in graphics applications such as 3DMark 11 is significantly lower than the GeForce GTX 680 GPU graphics card is GV-N680OC-2GD.
Also note that the power consumption of the test configuration and sample temperature of the GV-R797TO-3GD card is much higher than the GV-N680OC-2GD; Reaching 324W compared to 205.1W of GV-N680OC-2GD. In this case, readers will need 600 watts or more of power to ensure the power required to meet the entire system.
