nVidia has a 20 GB GPU with the same chip as 4070Ti, the model is RTX 4000 SFF.
One issue is price, it costs almost twice as much. Another one is memory bandwidth, RTX 4000 SFF only delivers 320 GB/second. That is much slower than 4070Ti (504 GB/second) and slightly faster than 4060Ti (288 GB/second). Also the clock frequencies are half of 4070Ti, so the compute performance is worse.
- XCSme 3y ago> RTX 4000 SFF Max Power Consumption - 70W. Huh?
- Const-me 3y agoThe power efficiency of the RTX 4000 is awesome, but it costs performance. The 4070 Ti runs at 2.3 GHz base clock / 2.6 GHz boost, the RTX 4000 SFF only runs at 1.3 GHz base / 1.6 GHz boost. For this reason, despite the chip is the same, the compute performance of the RTX 4000 is not particularly great. 4070 Ti delivers up to 35.48 TFlops at base clock, RTX 4000 only 19 TFlops.
- XCSme 3y agoHalf the TFflops but 4 times less energy consumption (4070ti is TDP MAX 285W)
