What is the difference in the power consumption of mainstream graphics

　　 What is the difference in the power consumption of mainstream graphics? more and more players are starting to focus on the power design of the graphics card. To this end, we have the current AMD and Nvidia mainstream graphics products have been tested to see the different products in the whole card power consumption, PCI-E slot to take electricity, video card external access to some of the different.

RX 480 video card "PCI-E slot power over" event caused the player to power the video card discussion

This video card power test platform is based on overclocking to 4.0GHz core i7-4770k processor and MSI Z97 MPower motherboard, configured with Chi Ripjawsz ddr3-2666 4gb*2 memory (the actual operating frequency is 1600MHz), Fujitsu 128GB Solid State Drive and Seagate 2TB Mechanical hard drive, the power is used in the first horse Gold 750W module version.

This test covers AMD and Nvidia's mainstream graphics and high-end flagship graphics, including AMD Radeon Pro duo/rx 480/r9 fury/r9 390x/r9 390/r9 380x/r9 380/r9 370X and Nvidia GeForce GTX 1080/GTX 1070/GTX 1060/gtx 980 ti/gtx 980/gtx 970/gtx 960/GTX, 950/GTX 750 Ti, etc. total 18 products (17 GPU), in addition to the special marking model of the Non-public version of the product, the rest are public version or F Ounders Edition products.

The test project is divided into standby and load tests, shutdown all foreground applications when the standby test, 5 minutes after the system desktop standby recording power data, load test using 3DMark Fire strike Comprehensive test, cycle run 5 minutes after recording power data.

First look at the machine state of the power of each video card, we take the card power consumption as a basis for the ranking from high to low, you can see that in standby power consumption, the use of dual-GPU design Radeon Pro duo can be said to be "a solo show", its standby power consumption up to 40W; And the second is the newly released RX 480 graphics card, its standby power is close to 20W, higher than the other single GPU models, while the lowest overall card power consumption is with RX 480 GTX 1060, its founders edition version of the entire card standby power consumption only 7W, Even the non-public version of the product is only about 10W, is also a very low level.

As a whole, the AMD Camp graphics products generally in standby power consumption is higher than the Nvidia camp, the latter standby power consumption of the highest GTX 980 TI is ranked in the seventh position, standby power consumption around 15W.

In the load power, the dual GPU design Radeon Pro duo continue to "a single show", over 400W of the whole card power to the player's power is a small challenge. and currently in the Limelight, RX 480 is in the middle of full load power, the whole card power consumption is around 165W, compared to its performance performance this power consumption is not high, but compared with the current largest opponent GTX 1060 graphics card is significantly higher than a section, the latter's entire card power consumption in 120W to 130W or so, GTX The power consumption of 1060 Founders Edition is not even 120W. The overall performance of the AMD Camp graphics card in the full load power than the Nvidia camp of the same level of products will be slightly higher.

In addition, in the PCI-E slot to take electricity, basically the parameters of the graphics card can be PCI-E socket control in the standard range, but the RX 480 graphics card in this part of the power is the highest, measured can be more than 70W, basically is barely qualified. And based on Fiji Core built R9 Fury and pro duo graphics, although power consumption is not low, but they are on the pci-e slot on the power is relatively low, only about 20W, the load on the motherboard is not very high.

Summarize:

From the above test results, the AMD Camp graphics products in power consumption than the same level of Nvidia products are still higher, which is consistent with our understanding. In the PCI-E slot power supply, although some of the products are pressed on the standard line, but generally comply with the specification. At the same time, we can also see that graphics card power consumption and pci-e slot is not the absolute relationship between the high and low, through the software and hardware design of the mutual cooperation, the power of the graphics card is not necessarily to the motherboard pci-e slot caused a very high power load.

But for PC power, strong and stable power supply is critical to the graphics card, so we have to configure the appropriate motherboard and processor, we must also configure a suitable power, so that you can have a truly stable PC platform.
