RTX 4060 Ti vs RTX 3060 Ti Performance: Lovelace GPU’s Low Memory Bandwidth Impacts Rasterization at 1440p and 4K

RTX 4060 Ti vs RTX 3060 Ti | Low Memory Bandwidth Impacts Rasterization

The RTX 4060 Ti is the RTX 3060 Ti’s immediate successor. Although the Lovelace GPU significantly improves rasterization performance at 1080p, it apparently falls short at higher resolutions like 1440p and 4K because of several dubious decisions made by NVIDIA, such as the limited bus width.

The RTX 4060 Ti 8 GB GPU, according to NVIDIA, performs up to 1.15 times higher at 1080p with DLSS enabled when compared to the RTX 3060 Ti. Curiously, the business made no mention of the board’s 1440p or, therefore, 4K performance. The RTX 4060 Ti’s high-resolution gaming performance is now visible thanks to reviews, and the results are, to put it mildly, less than desirable.

The performance gap between the RTX 4060 Ti and the RTX 3060 Ti, according to TechPowerUp’s evaluation, decreases as the resolution increases from 1080p to 1440p to 4K. With an average frame rate (FPS) of 131.4 for the games that were tested, the RTX 4060 Ti outperformed the RTX 3060 Ti at 1080p by 13%. With an average FPS of 96.5 for the RTX 4060 Ti and RTX 3060 Ti, respectively, the performance advantage for the Lovelace card shrank to about 10.5% at 1440p. The difference between the two cards at 4K decreased even more, to 7%, with the RTX 4060 Ti only managing an average of 4 FPS more than the RTX 3060 Ti.

Interesting results came from Hardware Unboxed’s review. The RTX 4060 Ti averaged 111 FPS at 1080p compared to 102 FPS for the RTX 3060 Ti, which is a 9% difference across the 15 titles the outlet tested. At 1440p, the performance difference between the two GPUs was only 5%, and at 4K, both the RTX 4060 Ti and RTX 3060 Ti delivered the same performance.

previous but not least, Gamers Nexus demonstrated the RTX 4060 Ti’s scaling issue in regard to resolution, with the RTX 3060 Ti from the previous generation nearly matching the Ada Lovelace board’s performance at 1440p and virtually matching it at 4K.

Why then does it seem that the RTX 4060 Ti’s performance does not scale well with resolution? The RTX 4060 Ti has a 128-bit wide bus and 288 GB/s of bandwidth, compared to the RTX 3060 Ti’s 256-bit wide bus and 448 GB/s of capacity, which may provide the solution to this question. Although NVIDIA asserts that the 32 MB of L2 cache significantly doubles the memory bandwidth of the RTX 4060 Ti from 288 GB/s to 554 GB/s, it doesn’t transfer well into actual gaming performance, as mentioned by Gamers Nexus.

In summary, it seems that the RTX 4060 Ti provides almost the same performance at 4K as the RTX 3060 Ti and is just marginally better when it comes to rasterization performance at 1440p without DLSS. It is hardly unexpected that shops claim to be anticipating minimal demand for the new RTX 40 mid-ranger given the US$400 pricing.
