Radeon RX 6000 series

The Radeon RX 6000 series is a series of graphics processing units developed by AMD, based on their RDNA 2 architecture.[1] It was announced on October 28, 2020[2][3] and is the successor to the Radeon RX 5000 series. The lineup consists of the RX 6800, RX 6800 XT and RX 6900 XT, with further variants including a Radeon RX 6700 (XT) series based on Navi 22 expected to launch in the first half of 2021.[4][5][6]

Not to be confused with the Radeon HD 6000 series, an earlier series of GPUs developed by AMD.

The lineup is designed to compete with Nvidia's GeForce 30 series of cards. These GPUs are also the first generation of AMD GPUs that support real-time ray tracing.

History

On September 14, 2020, AMD first teased the physical design of its RX 6000 series through a tweet shared on social messaging service Twitter. At the same time, the company launched a virtual island inside the video game Fortnite that contained a large-scale rendition of the RX 6000 hardware design, which players could freely explore using the game's "Creative" mode.[7]

AMD officially unveiled the first three cards of the lineup, the RX 6800, RX 6800 XT, and RX 6900 XT, in an event titled "Where Gaming Begins: Ep. 2" on October 28.[8] In the event, AMD announced the RX 6800 XT as its flagship graphics processor, claiming its performance "trades blows" with that of Nvidia's RTX 3080 graphics card in 1440p and 4K resolution gaming. The 6800 XT was announced with a price tag of $649 USD, which is $50 lower than the RTX 3080's starting price of $699.[8] AMD then introduced the RX 6800, and claimed that its performance was equal to or better than Nvidia's previous-generation RTX 2080 Ti in various games. However, the RX 6800 was announced with a $579 price tag, significantly cheaper than the 2080 Ti's $999 price tag.[8] Lastly, AMD introduced the RX 6900 XT as its highest card of the lineup, with a price of $999. The charts shown in the presentation compared it to Nvidia's $1499 RTX 3090, and AMD claimed the 6900 XT produces similar performance to the RTX 3090 but with lower power consumption.[8]

Release

Much like Nvidia's competing GeForce 30 series, releases sold out almost immediately, due to a combination of low stock and scalping bots.[9]

RX 6800 and 6800 XT

The RX 6800 and 6800 XT were launched on November 18, 2020, but due to low stock availability, they sold out at most retailers on the same day.[10][11][12] American retailer Micro Center restricted all sales to in-store only, claiming that stock "will be extremely limited at launch".[13] PCMag reported that stock for both cards on Newegg had sold out as early as 6:05 a.m. PST, and that stock was unavailable on AMD's own store website by 6:11 a.m.[11] Retailer B&H Photo Video outright refused to accept orders for the graphics cards, stating in part, "we do not know and are therefore unable to provide a date or time for when these items will become available to purchase."[11]

Scalpers were reportedly re-selling the GPUs on eBay for around US$1000 - $1500, roughly double the initial launch price.[10] Some frustrated social media users attempted to derail the listings by using bots to make fake bids on the scalped GPUs at absurd prices; in one instance, an auction for an RX 6800 XT saw bids go as high as $70,000.[14]

RX 6900 XT

The RX 6900 XT was launched on December 8, 2020, and similarly to the RX 6800 and 6800 XT, it sold out on the same day it was released.[15][16] According to PCMag, it was listed as out of stock on Newegg by 6:02 a.m. PST, just two minutes after it went on sale. AMD's store website, struggling to keep up with the high number of visitors, kept displaying 503 Service Temporarily Unavailable errors to customers attempting to buy the graphics card; by 6:35 a.m., it was sold out.[16]
