In the driver files for video cards, you can regularly find references to new models of graphics accelerators that have not yet been officially presented. So, in the AMD Radeon Adrenalin Edition 19.4.3 driver package, there were entries about the new Radeon RX 640 and Radeon 630 video cards.
New video cards received identifiers "AMD6987.x". Identical identifiers, except for the number after the dot, have graphics accelerators Radeon RX 550X and Radeon 540X. As you know, these are entry-level mobile video cards based on Polaris GPUs. And here the conclusion immediately suggests itself that we will not see junior video cards on the new Navi GPUs in the near future. Instead, we will again be offered the good old Polaris.
In general, it is not the first time for AMD to release video cards of the past generation under new names, βloweringβ them in the hierarchy. This is how the Radeon 540X and RX 550X went down a notch and became the Radeon RX 630 and 640, respectively. It is possible that the Radeon RX 560 will turn into the Radeon RX 650.
Note that rumors have repeatedly appeared earlier that the new generation of AMD video cards will be called βRadeon RX 3000β, so the mention of video cards of the 600 series turned out to be quite unexpected. The explanation for these discrepancies is simple: the Radeon RX 3000 family will include mid-range and high-end graphics cards on the new Navi GPUs, while the lower models will be included in the Radeon RX 600 series. Or the rumors are wrong, and all new graphics cards will belong to the Radeon RX 600 family Finally, the Radeon RX 600 series can only be represented in the mobile segment.
In the end, we recall that the Radeon 540X and RX 550X mobile video cards are built on 14nm Polaris GPUs. In the first case, there are 512 stream processors, while in the second there may be 512 or 640, depending on the version. The maximum GPU clock speed is 1219 and 1287 MHz, respectively. The amount of video memory GDDR5 can be equal to 2 or 4 GB in both cases.
