The most powerful board announced with the Navi chip fully enabled is the RX 5700 XT, equipped with a total of 40 computing units, 2560 stream processors, 8GB of GDDR6 memory and capable of reaching up to 1905 MHz. With Navi, AMD introduced a third frequency specification: the game clock. It takes into account the frequency that the card is expected to reach at high load, such as a long gameplay and a heavy game. According to AMD, in practice the RX 5700 should oscillate between the boost and the game clock, throughout the matches.
In performance, the board brings interesting gains compared to Vega 56 and GCN architecture. Even with 16 less computer units, it is capable of delivering significant performance gains. In comparison with rival Nvidia, according to AMD this board is at a performance level close to that of RTX 2070.
In the design of the reference board we again have the use of the blower, something that AMD said was efficient in a well refrigerated cabinet and that dissipates heat outside the cabinet. Mistakes made with Radeon VII seem to have been learned, and the company states that the fan profile has been adjusted so as not to exceed 43 decibels of noise production, even at high load. They are in total 7 phases (6+1) and the company seems confident that consumers will be able to extract more performance from the plate through overclocking. While the 3950X had a series of overclock demonstrations during AMD Tech Day, we still can't see how "you can climb" the RX 5700 XT, but AMD seems confident in the potential of the new microarchitecture.
The second model presented is the RX 5700. The board has the Navi chip partially disabled, with a total of 36 computing units. It is also more modest in clocks and power, with 6 phases. Otherwise it maintains similar configurations with a total of 8GB of GDDR6 memory. The competition for this board is with Nvidia's RTX 2060, with a focus on QuadHD, a resolution that AMD claims to have double-digit advantages in several titles.
Both models arrive on July 7, or 07/07 (a deliberate reference to the 7nm lithography of the Navi chip). Buyers of the new Navi cards will receive three months of subscription to Xbox Game Pass, Microsoft's games service that recently arrived on the PC and that brings more than 100 titles, including exclusive Microsoft at launch. The cards will be sold for $450 to RX 5700 XT and $349 to RX 5700.
