Of the graphics cards GeForce RTX 50 series before the end of 2024? The characteristics of the GPUs are slowly becoming clearer in any case.
Whether it’s Micron, SK Hynix or Samsung, the main companies in the world of video memory are firing on all cylinders. For two years now, they have been discussing the future GDDR7 at regular intervals.
Very recently, it was JEDEC which got involved in the “struggle” by validating nothing less than the specifications of the future standard. It was enough for the rumors around the GeForce RTX 50 series to be rekindled.
A memory bus up to 512-bit
Without confirmation/denial from NVIDIA, it still seems possible to see this new generation of graphics cards land between the end of summer and fall of this year.
Designed around the Blackwell architecture, the future GeForce RTX 50 series will need video memory capable of keeping up the pace and it is quite natural that GDDR7 is mentioned by several sources. The most recent rumor comes to us from a specialist in the genre, Kopite7kimi.
On for its most efficient card model.
GDDR7 28 Gbps for the high end
The GPU used would be called GB-202 and could also exist in a variant with a 384-bit bus, therefore identical to what we know today on the GeForce RTX 4090.
On this point, Kopite7kimi is not categorical just as he seems to be hesitating between a 384-bit bus and a 256-bit bus for the GB-203 GPU, little brother of the previous one. The downgrade would logically continue with the GB-205 (256 bit), GB-206 (192 bit) and GB-207 (128 bit). However, this information has changed quite a bit in recent months, so be careful.
On the other hand, Kopite7kimi seems sure of his fact when he asserts that the GDDR7 used on the next generation of GeForce will not be the fastest mentioned by JEDEC. Rather than 32 Gbps per pin, we seem to be moving towards 28 Gbps, in any case much superior to the 23 Gbps GDDR6X of the RTX 4080 SUPER.
Finally, note that, of course, not all GeForce RTX 50 series will be in the same boat. Added to the uncertainty around the memory interface bus is that of the type of chips used: undoubtedly the entry or mid-range models will not have this 28 Gbps GDDR7.
