Spotted by Overclock3D.net, the new XFX Radeon RX 460 features a dual-slot passive cooler with a rather hefty heatsink, which should have no trouble in cooling the smaller Polaris 11 GPU.
According to details provided by Expreview.com, the passive XFX Radeon RX 460 actually hits decent temperatures with heating up to 33 degrees in idle and 62 degrees under load. Of course, this depends on the actual airflow inside the case.
As announced earlier, the AMD Radeon RX 460 is based on Polaris 11 GPU with 896 Stream Processors, 48 TMUs and 16 ROPs. The reference version works at 1090 MHz base and 1200 MHz GPU Boost clocks, which is probably where XFX has left this card as well. It also comes with 4GB of GDDR5 memory paired up with a 128-bit memory interface.
The passive XFX Radeon RX 460 graphics card is perfect for those making a completely silent PC system or a HTPC. Unfortunately, due to a hefty heatsink and heatpipes, the passive XFX Radeon RX 460 is somewhat taller than your standard graphics card and also take up two slots. The good side of the story is that the Radeon RX 460 TDP is at below 75W so it does not need additional PCI-Express power connectors.
Unfortunately, passive XFX RX 460 is currently only available in Asia and there is no word if it will be launch in Europe or the US.
