On the seventh day of the seventh month of the year, AMD launched new processors and graphics cards, where the date alluded to the manufacturing technology 7 nanometers from TSMC. On the graphics card side, it was about the graphics family Navi with the new architecture Radeon DNA (RDNA) for the upper middle class.
The duo AMD Radeon RX 5700 XT and RX 5700 became the first step in the Navi saga and were wedged between previous graphics cards, where aging Polaris with the RX 500 series continues to be used in lower price ranges while outgoing Radeon VII had to continue to act as AMD’s master of the field .

Now the well-known leak “Komachi” reports that a new graphics circuit from AMD has been found in the database for Compubench. It is about Navi 14, with the code name GFX1012, which occupies a lower segment than Navi (10) which houses the latest Radeon RX 5700 series.
According to the database, Navi 14 is equipped with 24 calculation units in pairs of 2 according to the new architecture RDNA. This results in 1,536 stream processors and 96 texture units, compared to 2,560 stream processors and 160 texture units for full-scale Navi (10) in the Radeon RX 5700 XT.
The clock frequency for Navi 14 is set to 1.9 GHz, which with the computing units gives a computing power of just over 5.8 TFLOPS. This is quite precisely 40 percent lower than for the Radeon RX 5700 XT, something that should give an indication of its performance.
The results at Compubench show that the Navi 14 performs better than the long-distance Radeon RX 570, which is still a popular affordable alternative from AMD. It is worth mentioning that these are early results and that the performance can thus be better when the circuit with the associated graphics card is released.
In terms of the amount of memory, the listings are separated in the database. There are three models with 3, 4 and 8 GB of graphics memory, which could mean that Navi 14 will be used in several different models. In such cases, the 4 and 8 GB models should use a full-scale circuit with an associated memory bus of 128 or 256 bits, while the 3 GB variant cuts the bus width by a quarter.
Price information for graphics cards with the Navi 14 circuit is not yet known, but it is speculated in price tags around 200 USD. With the specifications in mind, it is also reasonable that it steps in as a direct replacement for the trio Radeon RX 570, RX 580 and RX 590, and gets similar price tags.
In addition to Navi 14, AMD is working on at least one other graphics circuit, where names such as Navi 12, Navi 21 and Navi 23 are common. Once Navi enters a higher performance segment, in addition to more computing units, it is expected to receive improvements in the RDNA architecture and support for ray tracing. By all accounts, the launch will be delayed until the beginning of 2020.
