AMD’s fastest Radeon RX 7000 “RDNA 3” laptop GPU could deliver RX 6950 XT and RTX 3090 performance levels

AMD is going to take a huge leap forward in laptop GPU performance with its next-generation Radeon RX 7000 “RDNA 3” chips.

AMD will bring Radeon RX 6950 XT and RTX 3090 performance to laptops with its Radeon RX 7000 “RDNA 3” GPUs

In two separate tweets from Greymon55 and Kopite7kimi, the two leakers reported that next-gen AMD Radeon RX 7000 “RDNA 3” laptop GPUs will deliver a huge boost to gaming performance on mobile platforms. First of all, we have Greymon55which says that the Radeon RX 7000 “RDNA 3” laptop GPUs (represented by the laptop emoji) would deliver comparable performance to the Radeon RX 6950 XT, AMD’s fastest RDNA 2 graphics card.

The second tweet from Kopite7kimi gives us a possible SKU name, the Radeon RX 7900M, which may or may not be the flagship RDNA 3 GPU given that the company is going to use the X950 XT brand for its superior RDNA 3 desktop graphics card. Either way, the Radeon RX 7900M would deliver comparable performance to the huge NVIDIA GeForce RTX 3090. Currently, no laptop GPU comes close to flagship desktop graphics cards.

AMD’s current fastest laptop GPU, the RDNA 2-powered Radeon RX 6850M XT, is only comparable to the Radeon RX 6700 XT (Desktop). NVIDIA’s GeForce RTX 3080 Ti laptop SKU is comparable to the RTX 3060 Ti and RTX 3070. So both laptop chips are a far cry from their desktop counterparts, but next-gen GPUs will step it up a notch and bring flagship-level performance. NVIDIA’s GeForce RTX 40-series mobility GPUs will include the AD103-based RTX 4090 as a flagship, as the AD102 GPU is too power-hungry for the laptop segment. AMD is going to do the same and is expected to use the Navi 32 matrix (MCM) for the laptop segment.

While next-gen laptop GPUs won’t offer the same performance as the fastest desktop cards based on the new architecture, it will still be impressive to see them match last-gen flagships while consuming only a fraction of the power.

The AMD Radeon RX 7000 “RDNA 3” line of GPUs based on the Nav 3x GPUs are set to launch later this year with reports pitting the Navi 31 flagship launch first followed by the Navi 32 and Navi 33 GPUs. We’ll likely get our first look at the RDNA 3 mobility lineup by CES 2023.
