XFX

XFX is the manufacturing division of Hong Kong-based Pine Technology Holdings Limited (SEHK: 1079). The XFX division has its headquarters in Ontario, California and specializes in the manufacturing of video cards, power supplies and motherboards.

Video cards

Originally, XFX only produced Nvidia graphics cards; however, during the beginning of 2009, XFX decided to begin manufacturing ATI (now AMD) graphics cards as well. Nvidia disapproved of this decision and removed XFX as an official partner. As a consequence, XFX was unable to produce any of the new ("Fermi") generation of Nvidia GPUs.

Warranty

All XFX graphics cards sold in the US or Canada previously came with a "double-lifetime" warranty. This warranty gave lifetime coverage to the original buyer and, in addition, a subsequent owner of the used graphics card. However, it was only valid if the card was registered with XFX directly within 30 days of purchase. In January 2012, with the introduction of its Radeon HD 7970 graphics cards, XFX silently discontinued its famous "double-lifetime" warranties, stating it was not sustainable. However, graphics cards with "Double Dissipation" or a product number that ends in "R" are still eligible for a single lifetime warranty if registered within 30 days.

AMD Radeon Rx 300 series

AMD Radeon Rx 300 is brand for a series of graphics cards. All used GPUs have been developed by AMD, produced in 28nm and belong to the same microarchitecture family: Graphics Core Next (GCN).

Devices based on the Fiji architecture, which include the flagship AMD Radeon R9 Fury X along with the Radeon R9 Fury and Radeon R9 Nano, are the first GPUs to feature High Bandwidth Memory (HBM) technology which is faster and more power efficient than current GDDR5 memory. However, the Rx 300-numbered GPUs in the series are based on previous generation GPUs with revised power management and therefore only feature GDDR5 memory. The Radeon 300 series cards including the R9 390X were released on June 18, 2015. The flagship device, Fury X, was released on June 24, 2015.

Core architecture

There are chips implementing all three iterations of Graphics Core Next. The table below details which GCN-generation each chip belongs to.

Ancillary ASICs

An ancillary ASICs present on the chips as well, are being developed independtly of the core architecture and have their own version name schemes.
