Performance without ReBAR does not change so dramatically over time. On the one hand, there are situations where ReBAR reduces performance and it’s good to know about them (so you can decide when to turn this feature off), and on the other hand, performance changes rapidly over time (which is true now, but may not be valid next week), the support grows, etc. And while results without Resizable BAR might already seem irrelevant, there are three main reasons why we’ll keep them and will continue to expand. After adding ReBAR support, the current model is impractical. You’ll get both in one publication from now on.

Anyone who has already noticed them in the last article can feel free to skip this part.Īs we announced in the RX 6700 XT review, we will no longer divide a test of one graphics card into two articles, where the results with inactive Resizable BAR were released first and then with active. Before we start with the Sapphire RX 6900 XT Toxic LE, we’re pointing out the changes in the structure of graphics card tests, which are discussed below in italics. Although only one version of each, you will still get a good idea of the performance differences. We need to be demanding and strict in this price category.īy supplementing the RX 6900 XT tests, we have tested all Radeons from the RX 6000 series. But it is also necessary to know about certain flaws that it has. There are several reasons to opt for this madness (in a good way). Still, it’s a rather controversial piece of hardware. The 360-millimeter liquid GPU cooling is a rare thing that will definitely attract attention. Overclocking the Sapphire Nitro+ RX 480 OC brings is extremely close to the GTX 980 and it just edges the Sapphire Tri-X R9 390X.The Radeon RX 6900 XT Toxic LE in the company of other graphics cards will not be overlooked. The graphics card doesn’t fare as well during the 1440p benchmark, but the overclock allows it to post a better Graphics score than a stock GTX 980. While it’s still some way behind an overclocked GTX 1060, the synthetic scores are good and showcases the benefits of overclocking. Here we can see the default boost mode clocks and the enhancements I managed using AMD’s WattMan software.Īfter the overclock was applied, the Sapphire Nitro+ RX 480 OC defeated the MSI GTX 1060 Gaming X running at stock settings. Before progressing, please disregard the extreme high fan speeds, which happened as a result of a bug discussed later in the review. On a more positive note, the memory overclocked by a decent amount and reached an average figure of 2126MHz. As always, your mileage may vary but it’s important to remember that overclocking beyond the heavy factory overclock core is always going to yield small gains. Please note, I did try to push the clock further and even added large amounts of voltage to no avail. Once overclocked, the boost clock hovers around 1360MHz, and a few slight drop offs bring the average down to 1359.8MHz. Thankfully, this doesn’t plague the Sapphire model and the improved cooling solution works wonders to prevent throttling. In contrast to this, the reference model had quite a sharp decline in its boost clock and behaved erratically. As you can see, the hefty factory overclock maintains a very stable 1342MHz boost and the core rarely drops from this figure.
Sapphire trixx minimize manual#
To easily outline the graphics card’s real world performance, I’ve included the average boost clock before and after manual overclocking. This is because manually selecting the voltage didn’t appear to aid stability or reduce temperatures when selecting a lower value than the automatic configuration.

Please note, the maximum power (50%) was applied as well as automatic voltage.
Sapphire trixx minimize driver#
Therefore, I deployed AMD’s new overclocking tool, embedded in the Crimson driver and slowly made adjustments to the core and memory. Unfortunately, Sapphire’s TriXX 3.0 utility isn’t quite ready and MSI Afterburner constantly causes stability problems when overclocking a wide range of AMD graphics cards.

By default, the Sapphire Nitro+ RX 480 OC is already tuned to a fairly high maximum boost which limits the amount of headroom for manual overclocking somewhat.
