Recent rumors about the next-generation NVIDIA GeForce RTX 4090 suggest that the flagship AD102 GPU-based gaming graphics card may be the first to break the 100 TFLOPs arithmetic power mark. For reference, the FP32 (single precision) arithmetic of the Ampere card king GeForce RTX 3090 Ti is in the 40-45 TFLOPs range.
Late last month, @Kopite7kimi shared his latest guesses on Twitter -- expect the next generation of flagship graphics cards from AMD and NVIDIA's next-generation flagship gaming graphics cards are both expected to break the 100 TFLOPs count mark.
As a major milestone in the consumer gaming graphics market, this generation of flagship gaming cards is also expected to see a spike in performance and power consumption -- from 275W to 350-400W and beyond (the RTX 3090 Ti is already over 500W).
The main reason for the power consumption surge is said to be that the AD102 chip could benefit from some major breakthroughs in TSMC's 4N process. Previously the GPU was rumored to be at 2.2 ~ 2.4 GHz, but the latest estimate has it at around 2.8 ~ 3.0 GHz.
Considering that Ada Lovelace provides 18432 CUDA cores, 96MB L2 cache @ 384-bit bus bit width, the stack of 12 GPCs contains x6 TPCs, 2 SMs per TPC (144 SMs total).

With a theoretical clock rate of up to 2.8 GHz, Ada Lovelace's flagship gaming graphics card could easily reach 103 TFLOPs of compute performance, with rumors hinting at higher acceleration frequencies.
But for now, it looks more like a peak frequency above the average "gaming" clock (similar to AMD's claim).
Compared to the Ampere King RTX 3090 Ti, 100+ TFLOPs means a more than doubling of compute performance, but it doesn't necessarily equate to overall gaming performance.
Even so, this is a huge upgrade in the gaming PC space (8.5x ahead of the Microsoft Xbox Series X gaming console by a factor of 8.5).
Also @Greymon55 speculates that the next generation of flagship gaming cards from Red and Blue may have 90+ vs 100+ TFLOPs of computing power.
If that happens, PC gamers at large can expect to drive the next generation of 8K (and even optical tracking) games more easily.
