AMD Upgrades Nearly All Radeon RX 5600 XTs to 14Gbps Memory

AMD appears to have finally cleared the confusion about Radeon RX 5600 XT performance. When that part launched months earlier there was a lot of confusion over AMD’s last-minute spec update, which cranked the “official” RX 5600 XT memory clocks up to 14 Gbps. Not all the memory chips on shipping RX 5600 XT parts were guaranteed to hit those memory clocks. As a result, only some OEMs updated their BIOSes for Radeon RX 5600 XT models to push memory clocks up. This led to a strange situation where 12 Gbps and 14 Gbps Radeon RX 5600 XT cards have been coexisting: they share the same name but perform substantially differently (and tend to cost different amounts). 

AMD’s list on their website now clears the air by indicating which OEM models from which OEMs actually support 14 Gbps memory. If you’re in the market for a Radeon RX 5600 XT, we strongly suggest that you pick up one of the models on this list. 

AMD Radeon RX 5600 XT Performance Benchmarks: Old vs New BIOS

In benchmark comparisons, we have found that the Radeon RX 5600 XT with 14 Gbps memory delivers almost all the performance of an RX 5700. A slight core overclock and upping the power limit can actually deliver performance that pips the stock Radeon RX 5700. In contrast, the 12 Gbps Radeon RX 5600 XT falls behind in performance and competes with the GTX 1660 Ti. We’re talking about a double-digit performance delta in places, making this official list a must-check before you make a buying decision.
