Bear in mind that while AMD did not significantly change the announced specifications as it is still the same 7nm Navi 10 GPU with 36 Compute Units (CUs) and 2304 Stream processors, the company has raised the TDP barrier by 10W (to 160W), raised the game and Boost clocks of the GPU, as well as instructed AIB partners to boost the 6GB 192-bit GDDR6 memory from 12Gbps to 14Gbps.
The GPU clocks were pushed from 1375MHz to 1615MHz for "game" and from 1560MHz to 1750MHz for the boost clock, while the memory clock was raised from 12Gbps (1500MHz) to 14Gbps (1750MHz).
This wouldn't be a big issue in general, as all it took was a simple BIOS update, but apparently, it was done just a few days or hours before the launch, depending on who you talk to. This means that some early shipped cards will not only come with an old BIOS, with lower clocked GPU and memory, but also some AIB partners have to update the design apparently.
On the consumer side, there will be a lot of difference between RX 5600 XT cards in retail/e-tail, as some partners decided not to change some of the specifications, and some early shipped cards will have the old BIOS, so it is left to the consumer to update it. While this is not a painful update, as it is just a matter of a simple BIOS update, made quite easy by AMD AIB partners, plenty of early buyers will not be even aware of the BIOS update.
Higher clocks enough for RX 5600 XT to beat RTX 2060
On the positive side, higher clocks for the GPU and the memory pushed the RX 5600 XT ahead of the RTX 2060, but it also got RX 5600 XT to higher power consumption, pushing it close and, in some cases, above the RTX 2060.
Bear in mind that RX 5600 XT beats the RTX 2060 by just a small margin, which not a great feat considering that the RTX 2060 launched just over a year ago.
While the MSRP is set at $280, which is a good price point considering that the RTX 2060 just dropped down to $300, some of those custom RX 5600 XT will sell at a higher price point, closer to $290, and in some cases even $300. Currently, the lowest priced one on Newegg.com is the standard PowerColor Radeon RX 5600 XT at $279.99, and the highest priced one is the ASUS ROG Strix RX 5600 XT at $339.99.
In the end, AMD made a big mess and it remains to be seen what kind of impact it will have on the market.
