NVIDIA’s budget Lovelace offerings will apparently be less impressive than initially expected. According to 3DMark TimeSpy Extreme figures shared by Kopite7kimi, the AD106 will be “just” 60-70% faster than the GA106. The x106 GPU core usually powers the RTX x060 which means that the RTX 4060 will likely be 60% to 70% faster than the RTX 3060. Although this is a sizable generation-over-generation improvement, it still pales in comparison to the higher-end Lovelace offerings.
The RTX 4090 and the 4090 Ti are supposedly both over 2x faster than their predecessors vis-Ã -vis the RTX 3090 and the 3090 Ti. It’s worth remembering that both the Ti models are based on the full-fledged x102 dies.
- NVIDIA RTX 4090 >2x Faster than the RTX 3090 in Leaked Bench: 3GHz+ Boost Clocks, 21Gbps GDDR6X Memory
- NVIDIA RTX 4090 Ti May be 2.3x Faster than the RTX 3090 Ti, 2.6x Faster than the RTX 3090 in TimeSpy Extreme [Rumor]
You can have a look at the 3DMark TimeSpy Extreme scores in the above table shared by @harukaze. As you can see, the RTX 4070 is also roughly 70% faster than the 3070. Similarly, the RTX 4080 is somewhere between 70-80% ahead of the 3080. The RTX 4090 and 4090 Ti, on the other hand, beat their respective predecessors by 2x or more.

NVIDIA’s first-party benchmarks should show larger gains on account of the massively ramped ray-tracing performance (and the cherry-picked titles).
