Evaluation Of The New Generation

The Fastest 3D Cards Go Head-To-Head
By

Some readers have complained about the lack of clear recommendations and awards for the new graphics cards. Since Nvidia and AMD put out their products at different times, no direct match-up has been made until now. This test is a perfect basis for comparison, since all graphics chips have completed the same benchmarks with the same test system. We have evaluated 3D performance, power consumption, price, and noise levels. To keep the evaluation simple, we award from one to four points for each category—the better the card does, the more points it is given.

The power consumption in watts is evaluated separately for the 2D and 3D modes, so there are points for both categories. The performance per watt has not been evaluated, as we are only interested in the overall efficiency of the samples. In 3D mode, the Nvidia cards are insatiable, while in 2D mode, AMD does poorly. Although all of the cards drop their clock speeds, the power consumption of the HD 4850 and HD 4870 remain high. At the moment, the high clock speed of the GDDR5 RAM on AMD’s HD 4870 has a negative influence on 2D power levels.

We have heard rumors that current versions of the PowerPlay energy saving function do not work properly. The clocking rate is reduced, but the voltage remains the same, which might explain the high 2D consumption.

GeForce GTX 280 (1024 MB) 117 130 352 3 1
GeForce GTX 260 (896 MB) 111 125 336 4 2
Radeon HD 4870 (512 MB) 147 0 288 1 3
Radeon HD 4850 (512 MB) 122 0 237 2 4

Power consumption, entire system, 2D = Desktop Vista, 3D = Full load

When it comes to noise levels, only the Radeon HD 4850 is reasonable. The HD 4870 is very loud, while the GTX 260 and GTX 280 generate extreme acoustic output under full load. The overclocked HD 4870 from MSI does not have a constant fan speed in 2D mode. Rather, the fan gets louder and then quieter again. A new VGA BIOS may solve this problem. The points are a mixed result of 2D and 3D.

2. noise level dB(A) 2D dB(A) 3D dB(A) Points
GeForce GTX 280 (1024 MB) 37.7 54.5 - 54.7 2
GeForce GTX 260 (896 MB) 38.1 - 44.2 53.5 - 54.0 1
Radeon HD 4870 (512 MB) 35.5 45.5 - 46.0 3
Radeon HD 4850 (512 MB) 36.3 41.2 4

The overall performance is quite clear; the gaps between values are not evaluated.

3. overall performance fps Percent Points
GeForce GTX 280 (1024 MB) 3765.6 127.0 4
GeForce GTX 260 (896 MB) 3464.8 116.8 3
Radeon HD 4870 (512 MB) 3355.7 113.2 2
Radeon HD 4850 (512 MB) 2965.6 100.0 1

This evaluation only shows the level of MSI overclocking in percent. The Radeon HD 4850 is supplied at default clocking, and is thus not included. To ensure that the evaluation is fair, the overclocked value is included in the end result once, and ignored once.

4. OC power 1920x1200 AA (MSI) Percent Points
GeForce GTX 280 (1024 MB) 5.8 3
GeForce GTX 260 (896 MB) 4.5 2
Radeon HD 4870 (512 MB) 3.5 1

Price is also quite clear, with the gaps between the figures not evaluated.

5. The price dollars Points
GeForce GTX 280 (1024 MB) 420 1
GeForce GTX 260 (896 MB) 290 2
Radeon HD 4870 (512 MB) 270 3
Radeon HD 4850 (512 MB) 180 4

On points, the Radeon HD 4850 is the clear winner. If you want a little more performance, though, you would be well advised to go for the HD 4870 or GTX 260, both of which represent serious competition for AMd due to price.

6. Evaluation of points without OC with OC
GeForce GTX 280 (1024 MB) 11 14
