In case you missed it, the Nvidia Geforce RTX 4070 is based on the same AD104 GPU as the RTX 4070 Ti, but a cut-down version with 46 out of 60 streaming multiprocessors enabled, leaving it with 5888 CUDA cores, 184 Tensor cores, and 46 RT cores. It has 184 TMUs and 64 ROPs, and comes with 12GB of 21Gbps GDDR6X memory with 192-bit memory interface, for a total of 504GB/s of memory bandwidth (same as the RTX 4070 Ti). The base GPU clock is set at 1920MHz and it Boosts up to 2475MHz. Of course, some factory-overclocked versions will have higher GPU clocks. Performance-wise, the Geforce RTX 4070 ends up significantly faster than its predecessor, the Geforce RTX 3070, and even faster than the RTX 3080, although it has a $100 lower launch MSRP. When compared to AMD, it manages to match AMD's Radeon RX 6800 XT. But Nvidia has another ace up its sleeve, which is better power efficiency, as well as better RT performance and DLSS 3.
As spotted by Techpowerup.com, there are no less than 19 different models in stock at Nvidia's own store, and nine are selling at $599.99 MSRP. Even the RTX 4070 Founders Edition is still available. Ten out of those 19 are selling at higher price, ranging from $609.99 to $699.99.
