The post RTX 40-series vs RX 7900 XTX/XT: Power draw and efficiency! first appeared on KitGuru.]]>
Today we take a closer look at power draw and performance per watt for both the Nvidia RTX 40-series and AMD RX 7900-series graphics cards. We do look at this as part of our day one reviews, but today's content dives deeper than just the average figures, as we analyse the power and efficiency data on a per-game and per-resolution basis for this new generation of gaming GPUs.

Some of you may already be familiar with the power testing we do as part of our day-1 GPU reviews here at KitGuru. It's a topic we've previously covered when we originally updated our GPU power testing methodology back in May 2021, and we've been including power draw and performance per Watt figures on a per-game, per-resolution basis in every single GPU launch review since then.

This video is primarily aimed at our YouTube audience, who may not see all of the content in our written reviews. It is still an interesting area of discussion, so if you haven't checked our our recently RX 7900 XTX and RX 7900 XT reviews, or either the RTX 4080 and RTX 4090, this is well worth a watch. Even if you did read the reviews but want a refresher, we cover several games in the video, each with varying results, before coming to the conclusion that Ada Lovelace has a clear efficiency advantage.

  • To read more about how we test power draw and efficiency, check out the article detailing our methodology over HERE.
  • For our latest data, with every single one of our power and efficiency charts, check out the RX 7900 XTX review HERE.

KitGuru says: Power draw and efficiency is an area of testing that I find particularly interesting, and hopefully this gives an insight into how we test, with a closer look at performance from all four current generation GPUs.

AMD RX 480 power draw issue to be fixed with driver this week https://www.kitguru.net/gaming/drivers/matthew-wilson/amd-rx-480-power-draw-issue-to-be-fixed-with-driver-this-week/ https://www.kitguru.net/gaming/drivers/matthew-wilson/amd-rx-480-power-draw-issue-to-be-fixed-with-driver-this-week/#respond Wed, 06 Jul 2016 14:51:27 +0000 http://www.kitguru.net/?p=298655 While AMD's new RX 480 graphics card has launched with positive reviews, it did run into one issue last week when a few publications discovered that the GPU was demanding more power from the PCI-e slot than it should be.

While AMD's new RX 480 graphics card has launched with positive reviews, it did run into one issue last week when a few publications discovered that the GPU was demanding more power from the PCI-e slot than it should be. Fortunately, despite some early speculation, this issue is fixable through software and AMD has been quick to respond with a driver update of its own- which should be available to the public in the next day or two.

With launch drivers, the RX 480 was found to be spiking in power, sometimes drawing 90W from the PCIe slot, rather than the 75W it should have been drawing. However, in an update last night AMD announced that this issue has been resolved and we can expect a new driver release this week.

3071401-9310_ellesmere_cam1_02_0010_4k

“Although we are confident that the levels of reported power draws by the Radeon RX 480 do not pose a risk of damage to motherboards or other PC components based on expected usage, we are serious about addressing this topic and allaying outstanding concerns. Towards that end, we assembled a worldwide team this past weekend to investigate and develop a driver update to improve the power draw. We’re pleased to report that this driver—Radeon Software 16.7.1—is now undergoing final testing and will be released to the public in the next 48 hours.”

So if you own an RX 480, then keep an eye out for Radeon Software version 16.7.1 over the next day or two as this should resolve any power-related issues. This new driver will also add a global setting to drop the overall power draw of the card if you would like to try and squeeze out some additional efficiency.

KitGuru Says: A GPU pulling more power than the PCIe slot is rated for could lead to some pretty serious issues down the line, so it is good to see that AMD has responded so quickly. Hopefully this update does the trick for all early RX 480 buyers. Are any of you planning on picking up the RX 480 at some point? Remember, we have teamed up with OCUK to give one away!

KitGuru has been scanning the airwaves, intercepting messages all over the place. We have already delivered 2 incisive articles today already on the GTX580, and there are plenty more to come it seems. To be honest, we've seen sieves that retain water longer than Taiwanese contractor can hold a trade secret. Still, their loss is your gain, right?  KitGuru is all about buying advice. So here's some more that you might find fascinating.

When the early GTX480 test results came to light, one of the most striking things was the power consumption. In a world where green issues colour almost every agenda, the first Fermi cards seemed horrendously inefficient. It made most professional IT journalists draw breath.

GTX580 should be with you next week at £429, but what will it cost to run in terms of electricity?

When Tom Petersen, technical director at NVIDIA, said back in July “GeForce GTX 480… in Quad SLI… Put simply, it rocks!” it made many of us wonder how he intended to supply the power needed by such a solution. It seemed that four of these cards alone would be enough to need a 1500w PSU, which is about as big as PSUs get in the current market. And that's before you power the mainboard, drives and overclocked CPU.

So nVidia quoted 250w, while some sites recorded 30-40w higher.

Fortunately or not, KitGuru Labs sit close to a massively powerful generator station. We're GTX580 Quad SLi ready!

Here's the interesting part, let's see what you make of it.

nVidia's partners in China are being told that the power envelope for the GTX480 will be under 290w.

Will GTX 580 be able to hit under the 290w and stay there, or will it actually need 300W+ to run under load?

KitGuru says: With a year longer to work on design efficiency, you would hope that nVidia has got its gorging power fetish under control. Delivering the fastest graphics chip on the planet under 290w at maximum load would be some feat. Churning through 300w or more would put some stress on the cooling solutions required. Can you imagine 4x GTX580 cards in Quad SLI burning up over 1200w?  Hot and sticky? Sure. Highly desirable anyway? Definitely!

Get hot and bothered or keep your cool with a quick comment below.
