HIS Radeon HD 6970 Turbo Graphics Card Review

Power / Temps / Noise / Overclocking

As the 6900 series and GTX 500 series perform power management in a different way to older cards we have changed the way we test power and temperature levels in recent reviews. For idle power we list the full system use at the wall after sitting at the desktop with no activity for 5 minutes. Load power is the highest reading we saw for the full system when testing during this review. Temperatures are taken in the same way. Noise levels are taken after a period of prolonged gaming in a scenario which applied maximum load to the GPU.

  HIS 6970 Turbo GeForce GTX 570
Idle Power 175w 184w
Load Power 340w 377w
Idle Temp 41°C 42°C
Load Temp 86°C 83°C

In the above tests we see that despite being an overclocked model the HIS Turbo is still able to produce better power performance than the GTX 570. Temperatures slightly favour the NVIDIA model however this is entirely down to fan profiles in the driver which aim to balance noise levels.

On the noise front we are happy to report that HIS have fine tuned the fan profile since we last reviewed a 6970 and the card no longer fluctuates in RPM regularly, it is a steady increase and decrease which is much more desirable.

Overclocking
Our HIS card is overclocked at the factory but despite this we were still able to increase the core and memory on the card using MSIs Afterburner utility or AMDs Overdrive. For this particular sample we were able to increase the core to 1000MHz and the memory went to 1500MHz with full stability. That’s an increase of 120MHz and 125Mhz over the reference design.

Here is the impact this overclock had on our 3DMark 11 performance.

  Stock Maximum OC 3DMark 11
HIS Radeon 6970 Turbo 900/1400 - 5447
HIS Radeon 6970 Turbo OC - 1000/1500 5888
