When AMD or NVIDIA launch new graphics chips ASUS is always amongst the very first manufacturers to show an entire new line-up of custom cards. The Radeon R9 380 2GB is based on AMDs Tonga GPU, which means the R9 380 is basically a rebranded R9 285, whereas GPU and memory clocks have been increased. There is a 256 bit memory interface and as the name of this card already suggests, this particular model ships with 2 Gigabyte VRAM. According to AMD graphics cards with this chip should be suitable for 1440p gaming. Whether this is true or not as well as quite a few other things, that's what we're going to check on the following pages.

As you can see from the GPU-Z screenshot below, ASUS decided to use a small factory-overclock on the new STRIX Radeon R9 380 2GB. While the reference Radeon R8 380 runs at 970 MHz GPU clock ASUS bumped the frequency by 20 MHz to 990MHz. A closer look at the memory reveals the AMDs board partner kept things at reference clocks. Checking frequencies with Furmark, meaning that we're applying maximum load on the GPU, we don't see any throttling at all regarind GPU as well as memory. The same applies for 3DMark. In this case, GPU-Z is telling us that the GPU frequency reamains at 990 MHz through the entire benchmark. This is also what we've noticed when running games, since there is no throttling whatsoever when running recent titles.
