AMD Navi 3x series GPU renderings leaked
AMD will launch Radeon RX 7000 series graphics cards this year, equipped with Navi 3x series GPUs based on the RDNA 3 architecture. Among them, Navi 31 and Navi 32 will be packaged in MCM multi-chip, consisting of GCD and MCD. The former is TSMC’s 5nm, and the latter is 6nm.
Recently, some netizens brought renderings of AMD Navi 3x series GPUs, and also revealed the possible sizes of these chips or modules:
- Navi 33 = 20.5 * 19.5 = 400mm²
- Navi 31/32 MCD = 4.68 * 9.36 = 44mm²
- Navi 32 GCD = 13.1 * 20.1 = 263mm²
- Navi 31 GCD = 13.1 * 28.2 = 369mm²
- Navi32 Total = 439mm²
- Navi31 Total = 633mm²
Size is only an approximation, but larger than previously expected. Navi 31 consists of one GCD and six MCDs, with 48 WGPs and 12288 stream processors. Navi 32 consists of one GCD and four MCDs, with 32 WGPs and 8192 stream processors. Navi 33 is not based on a small chip design. It is rumored that AMD has not adopted a 5nm process, and is still only a 6nm process. Although the cost is lower, the size of the chip will be larger.
AMD is expected to release GPUs based on the RDNA 3 architecture in the fourth quarter of this year, with Navi 31 first, followed by Navi 32 and Navi 33, but the latter two GPUs may also wait until early next year.
