AMD Updates ROCm Suite, Adds Navi44 to RDNA4 GPU List

TapTechNews May 24th news, AMD updated its ROCm software suite by adding the new RDNA4 GPU chip name - Navi44. This is also the second RDNA4 GPU that AMD has added to the ROCm hardware enablement list. These chips are expected to be equipped in the next-generation Radeon RX8000 series graphics cards.

The first is the Navi48 chip with the Gfx1201 name, and Navi44 uses the Gfx1200 name. The appearance of these two GPUs in the ROCm support list at least indicates that AMD is about to complete the development of at least part of the RDNA4 GPU.

This also shows a rather interesting naming change. AMD usually uses consecutive numbers in the past few generations of GPUs. For example, RDNA3 has three chips consisting of Navi31, 32, and 33; RDNA2 provides Navi21, 22, 23, and 24.

TapTechNews reported in April this year that the Navi4x series will adopt TSMC's N4P process. The overall design is the same as that of the Navi3x series, but only some old designs are deleted to increase the density of the GPU chip.

Navi48

Navi48 has 64 computing units, a 256-bit memory bit width, a 693 GB/s memory bandwidth, and an equivalent bandwidth of 2770 GB/s. The area of the GPU chip is 240 square millimeters (about 3.78 square inches).

Navi44

Navi44 has 32 computing units, a 128-bit memory bit width, and a 288 GB/s memory bandwidth. The area of the GPU chip is 130 square millimeters (about 2.03 square inches).

Navi44 should replace Navi33, whose parameters are the same, but the area of the latter's GPU chip is 204 square millimeters (about 3.19 square inches).
