Despite not yet adopting the new 6nm lithography from TSMC, the alleged Radeon RX 6950 XT, revised version of the enthusiast model of AMD gaming cards, should be able to reach higher clocks, surpassing the 2.5 GHz barrier. arrive courtesy of the leakers Greymon55 and Moore’s Law is Dead, which also reveal that the changes should be reflected in a notable increase in consumption.
RX 6950 XT can exceed 2.5 GHz and consume 350 W
According Greymon55, the new RX 6950 XT should deliver boost clocks above 2.5 GHz, which suggests that the solution should bring the most robust variant of the Navi 21 chip, the Navi 21 XTXH. The component is only present in some custom overclocking models and the integrated liquid-cooled variant of the RX 6900 XT.
6950XT boost seems to be over 2.5Ghz🤔

It is a GPU selected to achieve consumption levels and higher speeds than the standard, which is called a “binned chip”. Thus, the frequency range of the 6950 XT must be at least 250 MHz higher than the traditional model, and 65 MHz higher than that offered by the liquid-cooled variant.
probably 350W

Until then, only versions developed by partner manufacturers had managed to reach such high speeds, as is the case of SAPPHIRE Toxic Extreme, which reaches an impressive 2,730 MHz, and therefore it is not clear whether the novelty will employ air cooling, or if it will have cooling. liquid to extract maximum performance. Regardless, the increase will be reflected in consumption, which should reach 350 W, as the informant believes.
I can now 100% confirm the upcoming 6950 XT, 6850 XT, and 6750 XT are still on the same 7nm node as their predecessors.
That still leaves room for an above 10% boost when combined with 18Gbps memory, & thus I still expect the 6950 XT to be a far better product than the 3090 Ti.

Another important point reinforced by Moore’s Law is Dead is that AMD’s new enthusiast card should stick to the 7nm lithography, rather than adopting the 6nm as previously speculated, which may indicate that the gains on the chip should not be as marked as expected.
That said, the use of faster memories, going from 16 Gbps to 18 Gbps, should at least provide performance gains close to 10%, a bigger increase than expected by the leaker for the problematic RTX 3090 Ti, a direct rival of the 6950 XT, must offer.
Enthusiastic board expected to debut in April
At the same time, in response to leaks, the channel profile Coreteks suggested that the Radeon RX 6950 XT should arrive sooner than expected, in mid-April — previous rumors had indicated that the enthusiast solution would not be made official until June. However, this new deadline does not invalidate the debut window speculated in the past, as revisions of the RX 6800 XT and RX 6700 XT are also expected.
To be clear I only know of the 6950XT for mid-April (18gbps, faster clocks, 7nm) but it’s possible there are other skus – it’s just that I only know of this one as confirmed, sorry about any confusion https://t .co/t7aWUPK09w

Coreteks reveals that it only has information about the 6950 XT, which could mean that the other two simpler cards should be announced at a later time. These new models would also only bring higher clocks and boosted memory as novelties, which would end up significantly reducing their useful life, since their successors based on the RDNA 3 microarchitecture are already confirmed to arrive in 2022.
