AMD isn’t expected to launch its Radeon RX 7000 Series graphics cards until later this year, but leaker Greymon55 has provided an exciting teaser as to what the specifications of red team’s upcoming RDNA 3 flagship, the Radeon RX 7950 XT, will supposedly look like.

According to the leaker, who has clarified that this isn’t an April Fools’ joke, the Radeon RX 7950 XT will feature 15,360 streaming processors, 32 GB of GDDR6 (21 Gbps) memory, 512 MB of Infinity Cache, and a boost clock of 2.5 GHz. Its TBP is also said to be 500 watts, which, if true, would make it 200 watts higher than the Radeon RX 6900 XT.

Wccftech has suggested in its coverage that initial Radeon RX 7000 Series graphics cards will not debut with the new 16-pin PCIe Gen 5 power connector (12VHPWR), which is capable of supplying up to 600 watts of power via a single cable. Apparently, AMD doesn’t feel it’s stable enough yet.

AMD Radeon RX 7950 XT ‘RDNA 3’ Graphics Card Rumored Specs Detailed: 15360 Cores, 32 GB Memory, 512 MB Infinity Cache Up To 2.5 GHz & 500W TBP (Wccftech)

So based on the alleged information, the flagship graphics card within the Radeon RX 7000 series lineup, the AMD Radeon RX 7950 XT will utilize the flagship Navi 31 GPU configuration, rocking a total of 15360 stream processors that will be clocked in at 2.5 GHz. We don’t know if this is the max clock speed but it’s an 11% improvement in max clocks over the Radeon RX 6900 XT and delivers 38.4 TFLOPs of effective FP32 compute horsepower. That’s a 67% improvement in compute over the RX 6900 XT. The card will also feature a 200W higher TBP over the 6900 XT with a 500W TBP rating, an increase of 67% too.

As for the memory configuration, the AMD Radeon RX 7950 XT is expected to feature twice the memory capacity at 32 GB versus 16 GB on the current flagship. The card will retain its 256-bit memory bus interface but faster (21 Gbps) GDDR6 dies can allow AMD to hit higher than 512 GB/s internal bandwidth (Up To 672 GB/s). As for the Infinity Cache design, that also doubles with 512 MB onboard the Navi 31 GPU. These specifications sure sound monstrous and enough to tackle NVIDIA’s GeForce RTX 40 ‘Ada Lovelace’ lineup.

Another thing that I wanted to add is that we have heard from our own sources that AMD isn’t planning to adopt the new 16-pin (12+4) connector standard any time soon or at least on its Radeon RX 7000 series graphics cards. The reasoning we have been told is that AMD believes it isn’t stable yet but it looks like AMD’s design for the 7000 series was complete prior to the introduction of the standard.
