3.2 TessMark (OpenGL 4)

Hardware tessellation is one of the big features of Direct3D 11 and OpenGL 4 capable graphics cards. TessMark is a new benchmark focused only on the tessellation engine of DX11 class cards. It’s a pure tessellation benchmark, it does not contain complex shader or other heavy texture fetches. TessMark shows an overview of the tessellation engine raw power, that’s all. DX11 specifies that the tessellation factor can vary from 1.0 up tp 64.0. Of course, for tessellation factors like 32 or 64, most of the tessellated triangles are smaller than… a pixel. In those cases, tessellation is useless and in a real world application such as a game, high tessellation factors won’t be used. But in the case of a synthetic benchmark, it’s always instructive to see how cards can handle the whole range of tessellation level.

TessMark 0.2.2 has been used for the test.

Settings: 1920×1080 fullscreen, no AA, 60sec, map set 1.

TessMark - OpenGL 4 tessellation

Rule: The higher the number of points, the faster the card is.

Tessellation factor 8.0: moderate

53151 (888FPS) – EVGA GTX 580 SC
52188 (872FPS) – ASUS ENGTX580
48084 – EVGA GeForce GTX 480
38191 – MSI GeForce GTX 470
30512 – MSI N460GTX Cyclone 768D5 OC
27718 (462FPS) – Sapphire HD 6870, GPU core: 1000MHz
27469 (458FPS) – Sapphire HD 6970, GPU core: 880MHz
26223 – ASUS EAH6870
25480 (425FPS) – ASUS Radeon HD 6950
24161 (403FPS) – ATI Radeon HD 5870
23131 (386FPS) – Sapphire HD 6870
20745 – MSI R5770 Hawk

Remark: Cayman GPU implements AMD’s 8th generation tessellator (Barts is the 7th and Cypress is the 6th) and for low tessellation level, Cayman (HD 6970) should process tessellation twice faster than Cypress GPU (HD 5870). This is clearly not the case and this is certainly due to the OpenGL driver that has not been updated to reflect Cayman new architecture.

Tessellation: Cayman vs Cypress

550 (10FPS) – ATI Radeon HD 5870
539 (9FPS) – Sapphire HD 6970, GPU core: 880MHz
485 (9FPS) – ASUS HD 6950

Remark: Cayman GPU implements AMD’s 8th generation tessellator (Barts is the 7th and Cypress is the 6th) and for low tessellation level, Cayman (HD 6970) should process tessellation twice faster than Cypress GPU (HD 5870). This is clearly not the case and this is certainly due to the OpenGL driver that has not been updated to reflect Cayman new architecture.

3.3 ShaderToyMark (OpenGL 2)

ShaderToyMark 0.1.0 is an OpenGL 2 benchmark, developed with GeeXLab,
and focused on pixel shaders only. The pixel shaders are heavily based on math (few texture fetches) and then ShaderToyMark can be seen as a kind of GPU computing benchmark.

ShaderToyMark - OpenGL 2 pixel shader

Settings: 960×540 windowed, no AA, 60sec

316 points (52 FPS) – EVGA GTX 580 SC
306 points (51 FPS) – ASUS ENGTX580
263 points (43 FPS) – GeForce GTX 480
234 (39FPS) – Sapphire HD 6970
208 (34FPS) – ASUS HD 6950
189 points (31 FPS) – ATI Radeon HD 5870
184 points (30 FPS) – ASUS EAH6870
179 (29FPS) – Sapphire HD 6870
156 points (26 FPS) – MSI N460GTX Cyclone
104 points (17 FPS) – MSI R5770 Hawk
46 points (7 FPS) – GeForce 9800 GTX
36 points (6 FPS) – EVGA GTX 280
33 points (5 FPS) – GeForce GTX 260

Remark: ShaderToyMark is nice because it simply shows the raw processing power. The peak shader arithmetic (single precision FP) of the HD 6970 is 2703 GFLOPS and the one of the HD 6950 is 2253 GFLOPS.
The ratio between GLOPS is 2703 / 2253 = 1.19 while the ratio between scores is: 234 points / 208 points = 1.12.


3.4 Maxon CINEBENCH R11.5 (OpenGL 2)

CINEBENCH is an OpenGL benchmark based on Cinema4D.
