Power Consumption in Watts
by
Tino Kreiss
The power consumption measured here always represents the entire test platform (excluding the display). The 2D measurement is taken with Windows idling on the 2D desktop. The 3D value is determined while the graphics card and the CPU are under full load.
| Power Consumption in Watts | 2D | 3D |
|---|---|---|
| Geforce 8800 GTS (320 MB) | 130.5 | 200 |
| Geforce 8600 GTS (512 MB) | 96 | 147 |
| Geforce 8600 GT (256 MB) | 93.5 | 139 |
| Geforce 8500 GT TC (256/512 MB) | 87.5 | 121 |
| Geforce 8400 GS (256/512 MB) | 84 | 116 |
| Radeon HD2900 XT CF | 215 | 471 |
| Radeon HD2900 XT | 142 | 285 |
| Radeon HD2600 XT (512 MB) | 85.5 | 152 |
| Radeon HD2600 Pro (256 MB) | 82 | 136 |
| Radeon HD2400 XT | 84 | 128 |
| Radeon HD2400 Pro (256/512 MB) | 82 | 121 |

First ! e vai!
"The HIS card only comes with DVI connectors, which makes dual-link a sensible choice for the 1920 resolution."
Uh. No, it really doesn't.
The HDMI(1.2 and below) type A connector is equivalent to
a single-link DVI-D connector; the adaptor is purely
mechanical. Dual-link DVI is equivalent to the HDMI type
B connector, which is largely unused (although I have
hopes, because HDMI 1.3 type B can do 680MPix/s).
1920x1080p/60 fits quite nicely through the bandwidth
limit (165MHz) of an HDMI 1.2 type A connector, and
equally well through a single-link DVI connector -
as you can tell by the multitude of single-link DVI
24" 1920x1200@60Hz monitors on the market.
Dual-link DVI would give you 48bpp colour support at
1920x1080, but that's irrelevant if only a single link
is being used, via an HDMI adaptor. Also, the DVI
connector is perfectly capable of transmitting the
audio component of HDMI (the audio component uses the
same signal wires as the video), if it can be routed
to the card. Whether the content permits the audio to
be routed without HDCP is beyond my expertise.
Also, at the risk of testing my mathematical abilities:
"In Windows XP, the performance delta between the two cards in cumulative frame rate is now less than 20fps (Geforce 8800GTS 1878.9 fps, Radeon HD 2900 XT 1809.6 fps)."
That sounds like "less than 70fps" to me (not that it
makes much difference, obviously - they *are* close.)
