Technical Data / Specifications

You might be expecting this, with the Club3D Radeon HD 7790 '13Series you get a reference card with a reference PCB, a reference cooler and a shy overclock on the GPU. The ASIC quality measured on our sample was 67.6 % which is low compared with other cards we had in hand that were around 73 %.
About ASIC quality:



Looking at the clock speeds we see that the GPU runs at 1'030 MHz. That's not much of a factory overclock over AMD's 1 GHz recommanded clock, if you take a look at other cards on the market you see that most have the GPU clocked at 1'075 MHz. But it's better than nothing especially from the cheapest card on the market. Like most of the other Radeon HD 7790 out there no factory overclocking has been made regarding the GDDR5 memory which stays clocked at 1'500 MHz (6'000 MHz effective) following AMD's recommendations.

As said previously, this card from Club3D makes use of the reference PCB. Therefore you get an analogue power design with five phases, where the GPU gets four phases and the memory gets one phase.
The voltage regulation chip used for both GPU and memory is a NCP81022 from ON Semiconductor.
On the picture below you can see that the MOSFETs are cooled via a little aluminium heatsink. This one is not present on all cards from competitors.



It may looks strange but yes this is the so called reference cooler. It's been a while, that we've last seen a Zalman-like cooler on a graphics card. This one is being manufactured by NTK Technologies and features a copper base with aluminium fins and two 8mm heatpipes. The DC Brushless fan measures 65mm, is made by FirstDO and carry the part number FD7015H12S.



The memory chips used are made by Hynix and carry the model number H5GQ2H24AFR-R0C. They are specified to run at 1'500 MHz (6'000 MHz effective).
