Club3D Radeon HD 7850 Royal Queen review -
Hardware setup | Power consumption
Installation of any of the AMD Radeon cards is really easy. Once the card is seated into the PC make sure you hook up the monitor and of course any external power connectors like 6 and/or 8-pin PEG power connectors. Preferably get yourself a power supply that has these PCIe PEG connectors native (converting them from a Molex Peripheral connector anno 2012 we feel is a no-go).
Once done, we boot into Windows, install the latest ATI Catalyst drivers and after a reboot all should be working. No further configuration is required or needed unless you like to tweak the settings, for which you can open the Catalyst Control Center.
Let's have a look at how much power draw we measure with this graphics card installed.
The methodology: We have a device constantly monitoring the power draw from the PC. We simply stress the GPU, not the processor. The before and after wattage will tell us roughly how much power a graphics card is consuming under load.
Back in 2011 we decided to move away from Furmark and are now using a game like application which stresses the GPU 100% yet is much more representable of power consumption and heat levels coming from the GPU. We however are not disclosing what application that is as we do not want AMD/NVIDIA to "optimize & monitor" our stress test whatsoever, for our objective reasons of course.
Our test system is based on a power hungry Core i7 965 / X58 system. This setup is overclocked to 3.75 GHz. Next to that we have energy saving functions disabled for this motherboard and processor (to ensure consistent benchmark results). On average we are using roughly 50W to 100 Watts more than a standard PC due to higher CPU clock settings, water-cooling, additional cold cathode lights etc.
We'll be calculating the GPU power consumption here, not the total PC power consumption.
Measured power consumption
- System in IDLE = 157W
- System Wattage with GPU in FULL Stress = 263W
- Difference (GPU load) = 106W
- Add average IDLE wattage ~10W
- Subjective obtained GPU power consumption = ~ 116 Watts
Above, a chart of relative power consumption. Again, the Wattage shown is the card(s) with the GPU stressed 100%, showing only the peak GPU power draw, not the power consumption of the entire PC and not the average gaming power consumption.
Here is Guru3D's power supply recommendation:
- Radeon HD 7850 - On your average system the card requires you to have a 500 Watt power supply unit as minimum and 650 Watt if you go with two cards in Crossfire mode.
If you are going to overclock the GPU or processor, then we do recommend you purchase something with some more stamina.
There are many good PSUs out there, please do have a look at our many PSU reviews as we have loads of recommended PSUs for you to check out in there. What would happen if your PSU can't cope with the load:
- bad 3D performance
- crashing games
- spontaneous reset or imminent shutdown of the PC
- freezing during gameplay
- PSU overload can cause it to break down
Let's move to the next page where we'll look into GPU heat levels and noise levels coming from the graphics cards.
We test and review the Club3D Radeon HD 7870 Joker, this is the much discussed 7870 card that in fact has a 7900 series GPU, the Tahiti LE. For a fair amount of money this series 7800 product now offers 7900 series performance. Armed with 2GB of graphics memory it hits a sweet spot gaming performance wise and to date it one of the more popular products in the mainstream segment. Let's check out the Club3D Radeon HD 7870 Joker.
Club3D Radeon HD 7790 Crossfire review
In this article test and review the Club3D Radeon HD 7790 Crossfire incl Frametimes. If you need a little more value for money then the 13 Series R7790 might be just what you are looking for. This card is all about saving money and costs roughly 130 EUR. Have peek at our review where we'll test the 13 Series from Club3D.
Club3D Radeon HD 7850 Royal Queen review
Club3D jumped the 7800 bandwagon as well with several models, and for this review we'll be looking at their Radeon HD 7850 Royal Queen edition which comes with 1 GB of graphics memory. The product comes default in many ways, except the cooler. Club3D uses a small PCB and pretty slim dual-slot cooler making the card very easy to install. The graphics card is equipped with one 6-pin PCIe power connector. As mentioned the card comes default/reference clocked at 860 MHz and the memory is clocked at a 4800 MHz reference as well.
Club3D Radeon HD 6870 X2 review
We review the Club3D Radeon HD 6870 X2. A dual-GPU Barts based graphics card. AMD had nothing to do with this design, this is a custom design product. Admittedly we just love that stuff. So we'll head over into the review, we'll cover a thing or two about BARTS based processors, have a closer look at the Club3D Radeon HD 6870 X2.
