Here is an update of this post about Unigine Heaven 2.1 scores in OpenGL 4.0 and Direct3D 11 with tessellation in extreme mode.

Now that the Catalyst 10.5 driver is out with OpenGL 4.0 support, we can complete the test and see how Cypress transistors can play with OpenGL 4.0 tessellation.

First thing, Unigine Heaven works fine with Radeon HD 5000 series with OpenGL 4.0. So Catalyst 10.5 brings bugfixes compared to Catalyst 10.4 with GL 4.0 preview.

Here is an overview of the scores (extreme tessellation in 1920×1080):

- GeForce GTX 480: 916 (OpenGL 4.0)
- GeForce GTX 480: 970 (Direct3D 11)

- GeForce GTX 470: 719 (OpenGL 4.0)
- GeForce GTX 470: 768 (Direct3D 11)

- Radeon HD 5870: 316 (OpenGL 4.0)
- Radeon HD 5870: 532 (Direct3D 11)

- Radeon HD 5770: 258 (OpenGL 4.0)
- Radeon HD 5770: 364 (Direct3D 11)
- Radeon HD 5770 Crossfire: 695 (Direct3D 11) – OpenGL CrossFire does not work

Both NVIDIA and AMD offer better performance in Direct3D 11 than in OpenGL 4.0. But in the case of AMD, it seems the OpenGL 4.0 driver has really poor performances compared to the D3D one. But I’m sure that AMD’s OpenGL team will improve OpenGL tessellation speed.

Fun fact: according to this test, the GTX 480 is around 80% faster than the HD 5870 in Direct3D 11 and is around… 190% faster in OpenGL 4.0.. Please let me know if you notice an error in my numbers… It’s just not possible!

Here are the details of the test:

Testbed:
- Intel Core2 Extreme X9650 @ 3GHz
- 4GB DDR3
- Mobo: MSI P45D3 Platinium
- PSU: Antec TruePower Quttro 850W
- Win7 64-bit
- Unigine Heaven 2.1

肯定不會的啦,參考5870 獨大的時候,就沒見過幾個帖子

    with tessellation in extreme mode，准确说应该是OpenGL 4.0 细分曲面效能

那段时间比较繁忙的E大可能是度假去了吧，所以没心思打理论坛

E大好象说过没有5870测试样卡~

转个测试而已，看到些人真欢乐

费米专用测试，秒杀一切a卡

睡睡平安

nv太强了  秒杀amd全家 呀 全家

唉,老主板和A卡不兼容,现在主板和显卡都换了,A卡还是躺在抽屉里面

id似乎对OGL2.0很满意，也许要等到Tech6才会采纳OGL 4.0。

你可以在 opengl 3.x 上使用 instanced stream out 在 GPU 上执行 Tessellation。

看2家的历史 amd的软件是永远不可能有nv写的好了 就像nv的视频方面干不过ati一样
380 发表于 2010-5-27 20:01

为什么这两句话偶都觉得不对呢？
amd有几版驱动确实会抽风，不过NV也一样会出问题驱动。
视频方面，只要经过正确设置，N卡A卡的DVI输出都能做到一副样子，VGA输出NVIO完胜。

AMD/ATI那**一样openGL（ linux ）驱动，看的都想吐
