According to one Redditor, whose post was subsequently deleted, the specifications for a Radeon RX 5600 XT were posted for a brief moment, revealing some possible details about AMD's unreleased graphics card.
The Radeon RX 5600 XT reportedly features 2,304 Stream Processors (SPs), meaning it could be using the same Navi 10 silicon as the Radeon RX 5700. The graphics card was listed with 6GB of GDDR6 memory running at 1,500 MHz (12,000 MHz effective) across a 192-bit memory interface. The Radeon RX 5600 XT is allegedly capable of delivering up to 288 GBps of memory bandwidth, 35.5% lower than the Radeon RX 5700.

The Radeon RX 5600 XT allegedly operates with a 1,235 MHz base clock, 1,460 MHz game clock, and 1,620 MHz boost clock. The graphics card was apparently listed with a factory overclock so it's impossible to guess the reference specifications for AMG's GPU at this time.
The description, which reportedly appeared on ASRock's website, didn't specify the graphics card's TDP (thermal design power), but given the lower clock speeds, it should consume less power than a Radeon RX 5700.
The leaked card reportedly measures 240.6 x 126.5 x 53mm. It is said to sport one HDMI 2.0b port and three DisplayPort 1.4 outputs with DSC 1.2a support. This is the same configuration of display outputs on the vanilla Radeon RX 5700.
In summary, the Radeon RX 5600 XT appears to be a lower-clocked version of the Radeon RX 5700 with slower memory and a restricted memory bus. If the information is correct, it seems strange that AMD would offer the Radeon RX 5600 XT with 6GB of GDDR6 when the Radeon RX 5500 XT is available with up to 8GB.

Theoretically, you can downclock a Radeon RX 5700, and it would be a pretty good representation of the performance that you could expect from the approaching Radeon RX 5600 XT. Either way, you should still wait for our in-depth review.
The Radeon RX 5600 XT is anticipated to make its debut at CES 2020, which takes place at Las Vegas during January 7 to 10.

The Radeon RX 5600 XT may be closer to the Radeon RX 5700 than we think.
Well, other than the memory... which IF this leak is true, is even SLOWER than we thought - since not only is the bus narrower, but it's also clocked lower.

You'd have to REALLY underclock the heck out of the RAM to get down to 288GB/s and make sure you use settings that never exceed 6GB of memory, but probably.
