How can say this … is it a cut-down version of a RX 590 or a rebrand of a RX 580? I choose the latter.
Taken from TPU … An Expreview review of an XFX-branded RX 590 GME confirms that the the chip is indeed based on the “Polaris 20 XTR” silicon which is built on the 14 nm process. The card has GPU clock speeds that appear similar to reference clock speeds of the RX 590, with 1460 MHz base compared to 1469 MHz of the original RX 590. But this is where the similarities end. In its testing, Expreview found that the RX 590 GME is on average 5% slower than the RX 590, and performs halfway between the RX 580 and the original RX 590, which are differentiated by a roughly 10% performance gap. The 5% performance deficit would put the RX 590 GME on par with the new RX 5500 XT 4 GB, and trading blows with the GTX 1650 Super.
Thankfully, the RX 590 GME is priced lower than RX 590 cards (about 7.7% cheaper), and could be very region-specific. The fact that the RX 590 GME is being sold with full AIB partner branding and retail packaging, shows that this isn’t an OEM-only product. Read the complete review in the source link below.
