Just installed pics - Gigabyte 7950 CF - AMD ZeroCore and Heaven Bench

SteelSix · Apr 21, 2012, 05:15 PM

I thought about grabbing 7950 CF at product launch but held out. With the recent price cuts, I caved. Just got em running and wanted to share first impressions.

Gigabyte went with a plastic shroud for the latest WindForce cooler. IMO, a shroud should be sturdy enough to hold the card by without flexing or bending; this proved to be the case as it's fairly thick plastic. The metal bracket used to stiffen the PCB looks good too. Nice job Gigabyte:

Installed pic:

AMD ZeroCore
I run multi-gpu and surf nearly as much as I game; so I liked the idea of ZeroCore upon hearing about it. Does it work? Seems so.

Here's GPU1 in idle:

and GPU2 (notice GPU, memory, and temp numbers):

Worth noting, ZeroCore will not engage with GPU-Z running. GPU2 will sit at 800 core and 1300 mem.

Sure a Kill-A-Watt is not the most precise way to measure power consumption; but it's
cheap and shows ZeroCore works. Here's system at idle just before ZeroCore engages:

and after:

Unigine Heaven 3.0
Plenty of benchmarks already out there so I did a quick run of Heaven using 560ti 448 SLI @ 800 core and 7950CF @ 950 core. A mismatch, but all I had on hand. 560ti 448 SLI posts some respectable numbers though.

560ti 448 SLI, no AA, 4x AF, tesslation disabled:

No third card? Asrock board? Whut CPU clocks, stock? lulz. 57W is pretty good.

No third card yet.

It's an ASRock Extreme 7 w/16GB quad channel and i7 3820 @ 4.2. I've been lazy and let the bios auto tune the OC/voltage but it seems to do very well. It does 1.24v @ 4.2 and 1.008v @ 1.2 during idle. Next bios setting is 4.4. I'll try that some time soon.

Oh someone at AT caught this, CCC reports 20% fan speed on card 2. They're OFF though..

how is the second card when under zerocore mode at 0 degrees celcius? Should it not be lower than ambient?

The temperature sensors shut down when in zerocore or ulps mode.
