Nvidia's mid-range RTX 4070 is getting a new sub-variant featuring slower GDDR6 memory modules. Videocardz reports that Nvidia AIB partner Galax is preparing to launch a new aftermarket RTX 4070 dubbed the "OC 2X," featuring downgraded 20 Gbps GDDR6 memory modules. For extra clarification, this change only affects the RTX 4070, not the RTX 4070 Super, as far as we know.
The new GDDR6 RTX 4070 gets a new Ada Lovelace codename to accompany the memory change—AD104-251. This new AD104-251 RTX 4070 is slightly less potent than its (AD104-250) GDDR6X-equipped counterpart, featuring a measly 5% reduction in memory bandwidth. The original GDDR6X variant features 21 GBps modules, giving the original RTX 4070 504 GB/s of memory bandwidth. The new GDDR6 model reduces total memory bandwidth from 504 GB/s to 480 GB/s.
