amazon GPU DirectX 11 second generation reviews
Windows 7 appears to have brought DirectX 11 challenge to both users and graphics makers. AMD not only quickly supports DirectX 11, but also released the second-generation DirectX 11 GPU. This generation of GPUs quickly came to market through the Asus and GIGABYTE Gigabytes: Gigabyte GV-R687D5-1GD-B, GV-R685D5-1GD and Asus EAH6870 / 2DI2S / 1GD5.
The ATI Radeon HD 5000 series can be considered the first generation to support DirectX 11. Since October 2010, AMD has officially used AMD instead of the ATI brand on the Radeon HD 6800. Two Gigabyte GV-R687D5-1GD-B And the Asus EAH6870 / 2DI2S / 1GD5 both use the Radeon HD 6870 GPU; The Gigabyte GV-R685D5-1GD is based on the Radeon HD 6850 GPU. In addition to the Adaptive Anti-Aliasing antialiasing technology implemented during the rendering process, the new GPU lineup includes additional Morphological Anti-Aliasing (MLAA) Image processing after construction: The machine automatically detects vertices of high contrast, contrast, and blurring (based on the color of the adjacent points).
It uses the TeraScale architecture with 1GB GDDR5 memory, 256-bit interface, but the details are not the same. Gigabyte GV-R685D5-1GD has 775MHz clock, 960 stream processors, 4GHz memory pulses. The other two cards have 1120 stream processors, 4.2GHz memory pulses, but the Asus EAH6870 / 2DI2S / 1GD5 is clocked up to 915MHz, higher than the 900MHz standard of the GPU Radeon HD 6870.
Graphics cards use PCI Express 2.0 and feature AMD-specific technologies: Eyefinity allows for multiple monitors; Eye-Definition supports DirectX 11, OpenGL 4.1 library and enhances image quality by adding 24-bit anti-aliasing, 16x surface treatment filtering; EyeSpeed optimized for viewing HD video online; And has AMD HD3D technology supporting 3D display.
The GIGABYTE GV-R685D5-1GD is a powerful design with a WindForce 2X heatsink, while the two Radeon HD 6870s form a solid rectangular block with a standard squared cage radiator. Gigabyte GV-R685D5-1GD uses only one 6-pin, while Gigabyte GV-R687D5-1GD-B and Asus EAH6870 / 2DI2S / 1GD5 need two. All three cards are equipped with two DVI (with DVI to VGA adapter), and one HDMI to output HD content. The DisplayPort 1.2 is also equipped on the Gigabyte GV-R685D5-1GD and two Radeon HD 6870 cards (two ports).
Test Lab tests 3 graphics cards right on the 1600×1200 frame. The “warriors” pass the test game easily with very low score difference. With heavyweight games like Crysis, all three get 48fps.

Using the visual effects in 1600x1200x4AAx8AF mode, all three “warriors” continue to please gamers when conquering Doom 3, Quake 4, FarCry … Processing speed of all three. Almost equal in games and reduced by an average of 3.5% compared to the time the effects were not turned on. Asus EAH6870 / 2DI2S / 1GD5 outperformed the other two cards without slowing down on Doom 3 scores.
With 3dsmax 5.1 rendering software, test results show that the rendering capabilities of all three cards are good and exceeds 3 times the 30fps. However, the Asus EAH6870 / 2DI2S / 1GD5 proved less than two friends from Gigabyte (127fps / 140fps).
Test your gaming capabilities with 3DMark06 software, compared to other midrange cards, all three score high. The leader is the Gigabyte GV-R687D5-1GD-B with 8,942 points, followed by the Asus EAH6870 / 2DI2S / 1GD5 with 8,893 points and the remaining 8,865 points.
To test the strength of the warriors, Test Lab raises the resolution to 1920×1440. All three still calmly pass most of the experimental games at almost unchanged speed or only decrease 1%, 2% compared with 1600×1200 resolution. Particularly Gigabyte GV-R685D5-1GD when tested with F.E.A.R game speed reduced to 12%. Difference compared to two companions but compared to other midrange cards, the reduction of GV-R685D5-1GD is low. This result shows that all three test cards are more than capable of taking on more difficult tasks in more powerful games and increasing demand for graphics.
These three graphics cards are better than the Gigabyte GV-R587D5-1GD-B (A0912_52) graphics card (high-end Radeon HD 5000 series) at 1600×1200 resolution, ; Although prices are much lower. In contrast, the GIGABYTE GV-R587D5-1GD-B is slightly larger than the 3DMark 06, and the game’s processing speed when it comes to visual effects.
As mid-range stars, the price is reasonable, certainly three Gigabyte GV-R687D5-1GD-B graphics card, Asus EAH6870 / 2DI2S / 1GD5 and Gigabyte GV-R685D5-1GD will bring gamers or professionals some options of graphics processing are satisfactory.
