DX10: 3DMark Vantage

3DMark Vantage is a PC benchmark suite designed to test the DirectX10 graphics card performance. FutureMark 3DMark Vantage is the latest addition the 3DMark benchmark series built by FutureMark corporation. Although 3DMark Vantage requires NVIDIA PhysX to be installed for program operation, only the CPU/Physics test relies on this technology.

3DMark Vantage offers benchmark tests focusing on GPU, CPU, and Physics performance. Benchmark Reviews uses the two GPU-specific tests for grading video card performance: Jane Nash and New Calico. These tests isolate graphical performance, and remove processor dependence from the benchmark results.

  • 3DMark Vantage v1.02
    • Extreme Settings: (Extreme Quality, 8x Multisample Anti-Aliasing, 16x Anisotropic Filtering, 1:2 Scale)

3DMark Vantage GPU Test: Jane Nash

Of the two GPU tests 3DMark Vantage offers, the Jane Nash performance benchmark is slightly less demanding. In a short video scene the special agent escapes a secret lair by water, nearly losing her shirt in the process. Benchmark Reviews tests this DirectX-10 scene at 1680x1050 and 1920x1200 resolutions, and uses Extreme quality settings with 8x anti-aliasing and 16x anisotropic filtering. The 1:2 scale is utilized, and is the highest this test allows. By maximizing the processing levels of this test, the scene creates the highest level of graphical demand possible and sorts the strong from the weak.

Cost Analysis: Jane Nash (1680x1050)

  • $142 Radeon HD 5770 1GB costs $7.89 per FPS
  • $167 GeForce GTX 460 768MB costs $7.36 per FPS
  • $180 Radeon HD 6850 1GB costs $7.69 per FPS
  • $188 Radeon HD 5830 1GB costs $7.97 per FPS
  • $220 GeForce GTX 460 1GB costs $9.09 per FPS
  • $240 Radeon HD 6870 1GB costs $8.08 per FPS
  • $260 EVGA GTX 460 FTW 1GB costs $8.18 per FPS
  • $262 Radeon HD 5850 1GB costs $9.00 per FPS
  • $292 GeForce GTX 470 1GB costs $9.97 per FPS

3DMark Vantage GPU Test: New Calico

New Calico is the second GPU test in the 3DMark Vantage test suite. Of the two GPU tests, New Calico is the most demanding. In a short video scene featuring a galactic battleground, there is a massive display of busy objects across the screen. Benchmark Reviews tests this DirectX-10 scene at 1680x1050 and 1920x1200 resolutions, and uses Extreme quality settings with 8x anti-aliasing and 16x anisotropic filtering. The 1:2 scale is utilized, and is the highest this test allows. Using the highest graphics processing level available allows our test products to separate themselves and stand out (if possible).

Cost Analysis: New Calico (1680x1050)

  • $142 Radeon HD 5770 1GB costs $10.44 per FPS
  • $167 GeForce GTX 460 768MB costs $8.70 per FPS
  • $180 Radeon HD 6850 1GB costs $10.11 per FPS
  • $188 Radeon HD 5830 1GB costs $10.74 per FPS
  • $220 GeForce GTX 460 1GB costs $10.63 per FPS
  • $240 Radeon HD 6870 1GB costs $10.76 per FPS
  • $260 EVGA GTX 460 FTW 1GB costs $9.42 per FPS
  • $262 Radeon HD 5850 1GB costs $12.13 per FPS
  • $292 GeForce GTX 470 1GB costs $11.59 per FPS

Test Summary: Based on the 3dMark Vantage Jane Nash and Calico performance tests, it appears the Radeon HD 6850 competes directly against the Radeon HD 5830 and 768MB GeForce GTX 460. As far as price to performance value, the Radeon HD 6850 beats the Radeon HD 5830 but fails to match value with a 768MB GeForce GTX 460. At 1680x1050 resolution with extreme quality settings, the Radeon HD 5770 produced 18.0 FPS in Jane Nash compared to 23.6 FPS with the Radeon HD 5830, while the Radeon HD 6850 produced 23.4 FPS. In New Calico the Radeon HD 5770 produced 13.6 FPS compared to 17.5 FPS with the Radeon HD 5830, while the Radeon HD 6850 produced 17.8 FPS. Compared with a similarly priced EVGA GeForce GTX 460 FTW video card ($260), there's a substantial performance lead over the Radeon HD 6850, as well as the Radeon HD 6870. Unfortunately for Radeon fans, 3dMark Vantage doesn't make a strong argument in favor of the Radeon HD 6850 based on these results.

How is exhausting all heated air outside of the case a CON? This is a PRO if anything! I'm lost now.. Otherwise a pretty decent review. Thanks!

Nearly everyone agrees that hot air does not belong inside the computer case, heating up the processor and other components. We want the video card to exhaust the hot air outside the case, so everything stays cool and lasts longer.

"Cons:

- Fan exhausts all heated air outside of case"

It says - OUTSIDE of case.. that's why I was confused.

If this "We want the video card to exhaust the hot air outside the case, so everything stays cool and lasts longer." is the case, then why is it listed as con that's all...

I too, as an avid overclocker, agree and understand that hot air does not belong in the case, thank you.

Exactly one year later, and I'm making a typo correction. It now reads "Con - Fan exhausts all heated air back inside case"

Lol... still relevant, lots of people are still purchasing this card, including myself - two of them in crossfire can keep up with a 580 - and for less money and less wattage.

Thanks for the review and the clarification on the cons!

Hopefully my going overkill with case fans will help to negate this issue..
