Amd big navi 7nm leak

A new leak provides a new perspective on the chip size of AMD's next-generation Big Navi products. It is provided by AquariusZi, a trusted user on the PC Transportation Forum. In particular, the focus of the leak is the expectation of the AMD RX 5950 XT, which is a flagship 7-nanometer GPU that will reportedly use a huge 505 square millimeter chip, which shows that the performance of the RX is twice that of the existing 5700 XT.

At the same time, leaks indicate that AMD’s Navi 22 and Navi 23 GPUs will use 340 square millimeters and 240 square millimeters of chips. Navi 23 is expected to replace RX 5700 XT, which has a chip size of 251 square millimeters. As the source pointed out, to be safe, it is best to take into account the margin of error of 5mm2.

Although the RX 5700 XT has 40 compute units, according to rumors of these chip sizes, the Navi 21 GPU is expected to be able to increase it to 80 compute units. We should also consider the jump from RDNA1 to RDNA2, which will naturally improve performance greatly.

Although this is still speculative, it is worth considering that these estimates assume that the entire chip will be dedicated to the shader core. If AMD chooses to install dedicated ray tracing hardware, we can expect the number of CUs to decrease. However, the RDNA2 architecture and huge array size are designed to achieve twice the performance.

As for when we can hear AMD’s official news, all signs indicate that there will be news in the next few months. BRA certification of AMD cards has recently appeared in large numbers, and benchmark tests have also appeared on CubeVR. Similarly, the recent RRA certification of a large number of GPUs shows that they are the same as the four GPU code names that appear in the CEE file. They are Radeon RX 5950 XT, Radeon RX5950, Radeon RX 5900 and Radeon RX 5800.

Since NVIDIA is expected to launch the Ampere GPU next month, AMD may do the same soon.
