Great overcloking possibilities for this reference?
On October 28, AMD presented its Radeon Big Navi, available in RX 6900 XT, RX 6800 XT and RX 6800. The last two come out tomorrow, while the first will be desired until December 8th. We are currently finalizing our RX 6800 test and will deliver our verdict within a few hours. For those who wish to overclock their card, know that a certain CapFrameX reports having made its RX 6800 reach a GPU frequency of 2.5 GHz, without this causing the temperatures to rise too much.
On Twitter, the named CapFrameX reports a frequency of 2,532 MHz to be precise, with an average GPU temperature of only 60 ° C. The individual supports his statement with a screenshot which even mentions a peak at 2553 MHz. The average consumption of the GPU would be 208 W, with a peak at 269 W. By adding approximately 50 W for the memory, we can thus estimate the total consumption of the card at approximately 260 W; Big Navi’s appetite would therefore remain reasonable.
Not for all RX 6800 …
As a reminder, the values communicated by AMD mention a game frequency of 1,815 MHz and a Boost frequency of 2,105 MHz for the RX 6800. The gain reported here is therefore greater than 400 MHz, which would be quite impressive. Too bad the cooling method used is not specified: watercooling is not excluded.
Also, take this information with caution. AMD uses its Big Navi GPU, alias Navi 21, on the three references. The best parts are naturally intended for the RX 6900 XT (around 5-10% of production); those of good quality to the RX 6800 XT (30-50%); the rest to the RX 6800s. Therefore, it is quite unlikely that you will find excellent chips in the RX 6800s…
