The Radeon RX 7900 XT is said to have a memory speed of 20 Gbps

A solution armed with a Navi 31 GPU and which would land next November.

If you’re wondering when AMD will launch its RX 7000 RDNA 3 graphics cards, Greymon55 answers: next November. This same source, generally reliable when it comes to AMD’s plans, would also have information on the memory speed of the Radeon RX 7900 XT graphics card: 20 Gbit/s. Recall that the original RX 6900 XT has a memory speed of 16 Gbit/s; the maps of the série Radeon RX 6X50 XT (RX 6950XT, 6750XT et 6650XT) introduced memory clocked at 18 Gbit/s.

Moreover, Greymon expects one or more Radeon RX 7×50 XTs benefiting from a memory speed of 24 Gbit/s. However, these references would only arrive at the end of the life of this series of graphics cards. Anyway, a memory speed of 20 Gbit/s allows a memory bandwidth of 800 GB/s with a 320-bit bus, 960 GB/s with a 384-bit bus (without taking into account the Infinity Cache).

Sapphire offers a Radeon RX 6500 XT with twice the VRAM

Radeon RX 7000 Series Specifications

Finally, here are specs of the Radeon RX 7000 series suggested by Red Gaming Tech. It is likely that internally, the final characteristics of several references, especially those at the entry level, are still not finalized, so take the data in the table below with caution. the GPU Navi 31 would only arm Radeon RX 7900 series graphics cards, while the GPU Navi 32 and Navi 33 would power the RX 7800/RX 7700 and RX 7600/RX 7500 series respectively.

Graphic card	GPU	Stream processors	VRAM	Memory speed	Memory bus	Memory bandwidth
RX 7975 XT	Navi 31	12 288 (96)	24 Go G6	20 Gbit/s	384-bit	960 Go/s
RX 7950 XT	Navi 31	11 264 (88)	24 Go G6	20 Gbit/s	384-bit	960 Go/s
RX 7900 XT	Navi 31	10 240 (80)	20 Go G6	20 Gbit/s	320-bit	800 Go/s
RX 7800 XT	Navi 32	8192 (64)	16 Go G6	18-20 Gbit/s	256-bit	576 Go/s
RX 7800	Navi 32	7168 (56)	12*/16 Go G6	18*-20 Gbit/s	192*/256-bit	432 Go/s
RX 7700 XT	Navi 32	6144 (48)	12 Go G6	18*-20 Gbit/s	192-bit	432 Go/s
RX 7600 XT	Navi 33	5120 (40)	8 Go G6	18*-20 Gbit/s	128-bit	288 Go/s
RX 7600	Navi 33	4096 (32)	8 Go G6	18*-20 Gbit/s	128-bit	288 Go/s
RX 7500 XT	Navi 33	2560 (20)	6 Go G6	18*-20 Gbit/s	96-bit	216 Go/s

7900 series is 20Gbps, I don’t know regarding the rest.
