xbit测试
Testbed and MethodsWith the review of the Radeon HD 2900 XT we decided to use our new Intel Core 2 Duo-based system with Windows Vista OS. The configuration of our new testbed is as follows:
Intel Core 2 Extreme E6800 processor at 3.0GHz with 1333MHz processor system bus speed Asustek Computer P5N32-E SLI Plus mainboard (Nvidia nForce 680i SLI chipset) - Corsair DDR2 1066MHz memory (2x1GB)Maxtor MaXLine III 7B250S0 (Serial ATA-150, 16MB buffer)
- Creative SoundBlaster Audigy 2 sound card
- Enermax Galaxy DXX EGX1000EWL 1000W power supplyDell 3007WFP monitor (30", 2560x1600 max display resolution)
- Microsoft Windows Vista Ultimate 32-bitATI Catalyst HD2900_vista_8-37-4-070419a-046507E for the Radeon HD 2900 XT
- ATI Catalyst 7.4 for the Radeon X1000
- Nvidia ForceWare 158.19
ATI Catalyst:
- Catalyst A.I.: Standard
- Mipmap Detail Level: High Quality
- Wait for vertical refresh: Always off
- Adaptive antialiasing: On
- Temporal antialiasing: Off
- High Quality AF: On
- Other settings: by default
Nvidia ForceWare:
- Texture Filtering: High quality
- Vertical sync: Off
- Trilinear optimization: Off
- Anisotropic optimization: Off
- Anisotropic sample optimization: Off
- Gamma correct antialiasing: On
- Transparency antialiasing: On (multi-sampling)
- Other settings: by default
3ds maxAs the name suggests, the 3dsmax-04 scenario simulates a typical load on the graphics card in the Autodesk 3ds max suite. It uses geometrically complex models and from 5 to 7 light sources.
As you can see, the results of the Radeon X1950 XTX and both GeForce 8800 models are rather close, within 14-16fps, while the new Radeon HD 2900 XT is on the losing side. This must be due to its imperfect driver.
The frame rates are low. To get a higher frame rate, you should use a professional card from the Quadro or FireGL series.
CATIAThe catia-02 scenario is for checking out a graphics card’s performance in the design and modeling system CATIA V5R12 developed by Dassault Systemes. It uses models containing from 1.2 to over 2 million vertexes, performs antialiasing verification, and changes model display modes on the fly, including a mode with textures and lighting.
Nvidia’s gaming solutions recede into the background, leaving top place to the humble Radeon X1950 XTX. The new Radeon HD 2900 XT has the worst result again. It suits poorly for working in CATIA, at least with the driver we used in our test session.
EnSightEnSight is a scientific data animation and visualization tool. It is frequently employed in physics research, particularly when studying the dynamics of liquids, the interaction of liquid and solid substances, etc. Each frame of the ensight-03 scenario from SPECViewperf 9.0.3 contains 3.2 million vertexes and some modeling modes make use of lighting, shading and texturing.
The Radeon HD 2900 XT is not as slower than the other cards in this test as it has been in the tests above, yet it still has the worst results. First place goes to the Radeon X1950 XTX again, which is closely followed by the GeForce 8800 GTX.
LightScapeThe LightScape Visualization System uses advanced physical lighting model algorithms to deliver fully realistic lighting in 3D scenes. The appropriate SPECViewperf scenario includes both wire models and models with smooth shading. Its geometrically most complex frame contains a total of 2.8 million vertexes.
The Radeon HD 2900 XT performs well enough yet is no better than the Radeon X1950 XTX despite all of its architectural improvements and innovations. The GeForce 8800 GTS is on the losing side, but the average speeds of the cards is only within 13-16fps.
MayaThis 3D modeling suite is used widely for creating special effects in movies and in games development, too. This SPECViewperf scenario uses a lot of models, the most complex of which has over 16 million vertexes and uses texturing. This is a heavy load even for a professional graphics card specifically optimized for such work.
Yielding over 25fps, the GeForce 8800 GTX regains the lead, but the Radeon X1950 XTX has a good result, too. The Radeon HD 2900 XT cannot reach a speed of 20fps even – due to its imperfect driver, again.
Pro/ENGINEERWidely employed in modern industry, the Pro/ENGINEER software is a tool for computer-aided design of mechanical components. This test scenario contains models with a complexity from 485 thousand to 5.9 million vertexes.
The Radeon HD 2900 XT is a loser again with a speed of less than 5fps. The GeForce 8800 GTX can yield a mere 11fps in this test, though.
SolidWorksAnother computer-aided design system from Dassault Systemes, SolidWorks is a direct rival to Pro/ENGINEER. The sw-02 scenario simulates the operation of SolidWorks 2004 using two models: a car engine and a sports car.
The ATI Radeon X1950 XTX wins here like it has done in a number of earlier professional tests, notwithstanding Nvidia’s vast experience in developing professional graphics cards. Alas, the Radeon HD 2900 XT has nothing to boast about. Outperforming the GeForce 8800 GTS is the best it can do here.
UGS Teamcenter Visualization MockupImitating the VisMockup visualization system, this test renders a complex model of a car with different shading modes containing from 5 to 11 million vertexes. This is one of the most resource-consuming tests in SPECViewperf 9.
And again the Radeon HD 2900 XT finds itself in last place while its predecessor Radeon X1950 XTX takes top position, considerably outperforming the GeForce 8800 GTX. Unfortunately, the overall performance level is as low as 2-4fps. It won’t be comfortable to work under such conditions.
UGS NX 3NX 3 is a universal computer-aided design and development tool combining all stages of the development process: computer-aided design, computer-aided engineering, and computer-aided manufacturing. This SPECViewperf scenario contains a number of models of varying degree of complexity, up to 30 million vertexes with shading and lighting. This is going to be a hard trial for the graphics subsystem.
Having a well-balanced architecture that can only be let down by driver-related flaws, the GeForce 8800 GTX takes the lead here. It is followed by the GeForce 8800 GTS and Radeon X1950 XTX. The Radeon HD 2900 XT is lagging behind once again. This is indeed an ordeal of a test as you can judge by the extremely low performance of our gaming graphics cards.
怎么还不如r580？:wacko:
