Nvidia's RTX 4080 will be releasing in two flavours, each of which offers different allotments of CUDA cores and different amounts of GDDR6X memory. Both graphics cards offer gamers completely different performance profiles, forcing us to wonder why Nvidia did not call the 16GB model the RTX 4080 Ti, or their 12GB model the RTX 4070. Nvidia's RTX 4080 16GB and RTX 4080 12GB will be launching in November with MSRP prices of $1,199 and $899 respectively.
In A Plague Tale: Requiem, the vast majority of Nvidia's RTX 30/40 series lineup relies on DLSS to achieve 60+ FPS framerates. Note that this is without ray tracing enabled, which means that this game has the potential to be a lot more demanding. A Plague Tale: Requiem will support DLSS 3 at launch, giving Nvidia's RTX 40 series graphics cards a huge advantage over their RTX 30 series counterparts. Without DLSS Frame Generation, Nvidia's 12GB RTX 4080 would not be able to outperform Nvidia's last-generation RTX 3090 Ti.
In F1 22, we again see that Nvidia's RTX 40 series benefits greatly from Nvidia's DLSS 3 technology, and that Nvidia's RTX 4080 12GB cannot outperform Nvidia's last-generation RTX 3090 Ti without it.
Once again we see a hige performance gap between Nvidia's RTX 4090 and TX 4080 16GB, suggesting that there is space for an RTX 4080 Ti model if AMD decides to exploit this gap in Nvidia's RTX 40 series lineup.
With Microsoft Flight Simulator, we once again see that DLSS 3 has a huge impact on the performance profile of their RTX 40 series GPUs. We also see that Nvidia's RTX 3090 Ti can also outperform their RTX 4080 when DLSS is disabled, even if only marginally.
Nvidia's RTX 40 series relies on DLSS 3.0 to generate most of its promised performance gains. Here, the TX 4080 12GB is a lot further behind the RTX 4080 16GB than in other games. Maybe Nvidia should have called this GPU their RTX 4070, or RTX 4070 Ti.
