NVIDIA has allegedly scrapped the original variant of the GeForce RTX 4070. Like the RTX 4070 Ti (formerly the RTX 4080 12GB), it is based on the AD104 core. It will feature 7,160 FP32 FP32 cores across 56 SMs and will be paired with 12GB of GDDR6X memory across a 192-bit bus. The graphics core will be clocked around 2.3GHz with a boost of 2.6GHz. The memory will run at 21Gbps with a 48MB L2 cache buffer, resulting in an external bandwidth of 504 GB/s and a much higher internal throughput.

According to Kopite7kimi, the original RTX 4070 was based on the AD104-275 core but has been scrapped. I’d say we’re getting a wider GPU based on the AD104 die with the same 12GB GDDR6X memory and 192-bit bus, but it’ll all be up in the air now.
Anyway, the GeForce RTX 4070 Ti will be announced at CES next month, followed by a Jan 5th launch. The RTX 4070 should land a month or two after, most likely in early March, with a price of $799.
