Performance Test of New Generation Notebook GPU at different Power: RTX 4080 plus 20W can catch up with RTX 4090

CTOnews.com February 11 news, foreign media ComputerBase tested the performance of Nvidia RTX 4080 and RTX 4090 notebook GPU at different power consumption.

According to reports, the full power consumption of the Nvidia RTX 4080 and RTX 4090 notebook GPU is 150W + 25W dynamic power consumption, and the tested game is Shadow Samurai 3 with 1440p resolution.

According to the test results of foreign media, the performance of RTX 4080 under 150W GPU power consumption is the same as that of RTX 4090 under 125W. The performance levels of RTX 4080 and RTX 4090 increase almost in parallel in the range of 80W to 150W power consumption. Before reaching the highest power consumption, the RTX 4080 can reach the RTX 4090 level by increasing its power consumption by about 20W.

The first batch of RTX 4080 and RTX 4090 games are flagship models that basically achieve full power performance, so it is unlikely that the RTX 4080 model will have higher power consumption than the RTX 4090 model. The upcoming series of games from RTX 4050 to RTX 4070 are hard to say, and it is possible that RTX 4070, which has insufficient performance release, will underperform RTX 4060. Pay attention to the performance of the player friends in the purchase should pay more attention.

The following figure shows the performance comparison between RTX 4080 / 4090 notebook GPU and desktop graphics card at different power consumption drawn by foreign media:
