![]() The boost algorithm does not work very smart, sometimes even wastefully, when the frame rates are limited which is done very often in practice. However, a closer look reveals clear weaknesses for the competitor with the green logo. Generally, graphics cards from Nvidia and AMD are considered to be similarly efficient which is surprising considering AMD's manufacturing advantage (TSMC's 7nm process). You can also reproduce this behavior with other members of the Ampere generation as ComputerBase e.g. That's a difference of more than 40% and it's not even the maximum possible optimization potential. The power consumption drops from over 190W to about 110W. On the left, after manually adjusting the voltage/frequency curve, you can see how extremely wasteful the boost algorithm is. ![]() It strikes one that the core clock and voltage are maxed out, although the load at 1080p is relatively low. On the right side of the comparison chart below you can see the sensor data of the RTX 3090 with stock settings. However, this article is not about the general efficiency of the chip, but about the boost behavior of the graphics card. The RTX 3070 Ti which uses GDDR6X is considered to be very inefficient. Since some users on Twitter criticized the choice of the graphics card for this test I would like to add another example using the RTX 3090 in Shadow of the Tomb Raider. The boost algorithm shows significant optimization potential. The Strange Brigade results at 1080p doesn't even look that bad for the Nvidia card but this is no longer true turning towards the 1440p numbers. With 120 and 144 FPS limits the power consumption of the RTX 3070 Ti is clearly too high. Measurements with Battlefield V alongside the other titles show that the boost algorithm acts wastefully. As a result the RTX 3070 Ti's power consumption is much higher, saving potential isn't utilised. The card boosts almost identically across all settings. Shadow of the Tomb RaiderĪt 1080p and with a 60 FPS limit a serious weakness of the Nvidia card's boost algorithm becomes apparent. Without the limiter the AMD card needs more energy but the frame rates are also higher. Although the GPU core clock of the RTX 3070 Ti is higher the power consumption is significantly lower. An exception to this is the 1080p scenario with a 60 FPS limit. Using an FPS limiter the power consumption of the Nvidia card is significantly higher. The GPU utilization is already very high at 1080p. These titles are characterized by high frame rates even at 1440p. The GPU core clock frequency and power consumption of the graphics cards were measured in 4 games. Some of the measurements were cross-checked with an RTX 3090 (stock). The graphics cards were consistently operated stock. A PowerColor Red Devil Limited Edition Radeon RX 6800 XT and an ASUS ROG Strix RTX 3070 Ti were used for this test. The R9 5900X was cooled with the Noctua NH-D15 chromax.black. A be quiet! Dark Power Pro 650 watt power supply provided the components with power. The Gigabyte X570 AORUS MASTER was mounted horizontally on test bench. 1% percentile, which is not sensitive to reproducible and especially random outliersĪn open test bench without further active cooling was used for the gaming benchmarks. ![]()
