AMD R9 380X Specifications leaked

AMD Reportedly Readies R9 380X GPU

AMD R9 380X rumored to launch in late October with 4GB of GDDR5 Memory


It is rumored that AMD will launch their R9 380X will launch in late October or early November with 4GB of GDDR5 Memory, meaning that it will only be using a 256-bit memory bus instead of the silicon’s full 384-bit memory bus like was previously though. 

This will mean that the new GPU can be made using the same, or lightly modified versions of the PCBs used for producing AMD’s existing R9 380 GPUs, which will allow this GPU to be made at a reduced cost. Sadly this will mean that the GPUs full 384-bit bus size will not be used by the GPU, which will reduce this GPUs maximum memory bandwidth and mean that it will have to be used with a lower amount of memory. 

This chip will take advantage of the price gap which is between Nvidia’s GTX 960 and GTX 970 GPUs and should fit neatly between AMD’s existing R9 380 and R9 390 GPUs. If recent rumors are correct this GPU will have 2048 GCN 1.2 GPU cores and a 256-bit memory bus. 

Below is a chart comparing the specifications of AMD’s R9 380 and R9 390 GPUs to the rumored specifications of AMD’s upcoming R9 380X.

In essence the R9 380X will be the same Tonga based GPU that Apple used in their 5K iMac, which at that time was named the R9 m295X.

Right now the specifications of this GPU remain unconfirmed, but we do have pictures of a XFX prototype of this GPU, which looks like it features removable fans which will allow this GPU to be very easily cleaned.

With such a huge price gaps between the mid-range GTX 960 and GTX 970 this is a great opportunity for AMD to take advantage of this market gap, let’s hope these rumors of an AMD R9 380X GPU are true and that this GPU is as impressive as it sounds.
