Radeon RX 7700 XT: AMD’s future RDNA3 graphics card should hit hard

The YouTube channel Moore’s Law is Dead unveiled in a video the supposed main characteristics of AMD’s Navi 33 chip. Under RDNA3 architecture, the latter should notably be used to power the future Radeon RX 7700 XT.

Little by little, the contours of the next generation of graphics cards from AMD are emerging. In a video posted recently, the YouTube channel Moore’s Law is Dead (MLID), known to echo leaks related in particular to computer architectures, lists the latest information available about the Navi 33 chip. A chip that should be found on board a certain Radeon RX 7700 XT.

A powerful but compact chip, engraved in 6 nm

In this case, the Navi 33 chip would be positioned on the mid-range. It will probably be an optimization of the current Navi 21 chip, which will use AMD’s new RDNA3 architecture, but also TSMC’s 6 nm engraving. If the RDNA3 architecture will bring together multi-chiplet solutions, notes WCCFTechthe Navi 33 chip would be of the monolithic type and would measure between 360 and 460 mm² according to MLID. His die could thus settle for a surface 30% smaller than on the Navi 21 GPU, whose die stretches 520mm².

The main leaks about the Navi 33 chip suggest for the rest that it would be coupled with 8 GB of GDDR6, faster than on current cards. The chip would develop a level of performance similar to what the current RX 6900 XT offers, but with better support for ray tracing.

Its limited amount of memory compared to the RX 6900 XT (which has 16 GB of GDDR6) would however force the card to be intended more for gaming at 1440p. Its performance in 4K would indeed be upset by the presence of 8 GB of VRAM “only”.

Eye-catching specs

With its Navi 33 GPU, the Radeon RX 7700 XT would be limited to around 200W of TGP, we are told WCCFTech, which also relays the architectural specifications of this new GPU chip. In particular, there would be two Shader Engines with two Shader Arrays each (2 per Shader Engine, i.e. 4 in total). Each Shader Array would be made up of five WGPs (10 per Shader Engine, or 20 in total), and each WGP would consist of 8 SIMD32 units with 32 ALUs. These SIMD32 units would form a total of 5,120 cores, which is as much as the RX 6900 XT.

The Navi 33 chip would also be equipped with 128 to 256 MB of Infinity Cache. Finally, we learn that the GPU would include a total of four 32-bit memory connection links, for a global memory bus of 128 bits.

The Radeon RX 7700 XT which would be equipped with it would be limited to a price placement between 400 and 500 dollars. A rather attractive positioning for a chip that promises to be comfortable in 2K definition, with ray tracing activated.
