![]() ![]() How it will compare to today’s CrossFireX solutions is yet to be seen. Having support for Nvidia SLI will help us to achieve 60 fps or more. At the current time, AMD doesn’t offer a dual-GPU version of an HD 6000 card, but if all goes according to plan, we should be seeing the HD 6990 in early 2011. Support for Nvidia SLI or AMD Crossfire Dear Kojima Production and 505 Games. There’s not a lot to discuss here that hasn’t been touched upon in our launch article, but for the sake of interest, you can review AMD’s current line-up below. The GPU dies are of course varied between the two, but on the larger of the two cards, HD 6970, an 8-pin connector is required along with a 6-pin – rather than require two 6-pins. As you can no doubt tell, the cards all look identical, and for the most part, there’s little different between them. In the photo above (can you tell that my camera’s external flash is broken?) sits AMD’s Radeon HD 6970 and HD 6950 – two of each. In some rarer cases, we can even see that 200% mark exceeded, which goes to show just how mature these configurations are in today’s landscape. In the earlier days of multi-GPU, we’d be lucky to see 150% of the performance of just one card, but today, when paired with the right software, we can actually see performance increases of up to 200%. One thing’s for sure, though, and that’s that dual-GPU tech has improved vastly ever since its introduction. NVIDIA touts more often than AMD that its dual-GPU solution is superior, and that’s something we’d like to put to an honest test. One aspect we haven’t tackled in the past, but we plan to in the near-future, is CrossFireX vs. Interest is definitely waning on the mainstream side for Nvidia, with it nixing support for SLI on its most popular cards, the GTX 1060, leaving only its higher-end cards available to pair up for. This process is identical to NVIDIA’s SLI, and software-wise, both AMD and NVIDIA offer similar feature-sets. After both cards are installed and power connectors hooked up, all that’s needed is a simple CrossFireX bridge to mate the cards. So, to help fill in that void, this article will tackle dual-GPU HD 6950 and HD 6970 configurations across our regular suite.Īs we’ve come to expect from AMD, pairing up two GPUs to act together is a simple process. That is not a bad thing, but 2.0 at X4 not as fast as 3.0 X4.AMD a couple of weeks ago released its first Radeon HD 6900 graphics card models, and at the time our article was published (about a week late due to various circumstances), we were unable to include CrossFireX performance as we had hoped. ![]() Now, as far as your board goes, the bottom X4 slot is running at 2.0 speeds. You are still down to about 15% reduction in FPS compared to a system running X16, x16, X16. Now, lets say you turn of some of the features to get your PCIe to X4. Will it work? Yes, will it perform well? For having 3 cards, yes, but it is not ideal. The bottom card in the X1 slot, now becomes a bottleneck in your SLI setup. Now, you thrown the X1 into the mix, you are going to see about a 20% reduction overall vs X8 or X16. X8, you get about a 5-10% reduction in FPS vs a system running full X16 X16. There are only 3 full size PCIe slots so you can't use 4 whole cards.Īs far as my board goes, I can TECHNICALLY do 3 cards because I have 3 slots to put them in, the problem is that it will only be running at X1 vs the X4 if I were to turn off my usb 3.0 ports (4 of them) and 2 of my sata parts. When they say quad, I believe they mean a pair of dual GPU cards, like a pair of 690s. Supports AMD Quad CrossFireX™, 3-Way CrossFireX™ and CrossFireX™ Thus, 3 way crossfire is supported, but not 3 way SLI. However this will only work with crossfire, as SLI requires x8 bandwidth. CrossFire came out with a huge overall scaling lead over SLI, and removing the one title that didn’t reflect that average would have made the lead even bigger. GeForce GTX 460 baru membuat kami duduk dan memperhatikan, terutama saat kami memasangkannya dalam konfigurasi SLI dua kartu. This slot can also be used for a third card, even though it's slower. 1 x PCI Express 2.0 x16 slot (PCIE5: x4 mode) This means those 2 slots can run at x16/x4 OR x8/x8, the latter is better for multi gpu setups. 2 x PCI Express 3.0 x16 slots (PCIE2/PCIE4: single at x16 (PCIE2) / x8 (PCIE4) or dual at x8/x8 mode) This can all be found in the motherboard manual. It may also drop to x4 for certain slots. If only the main slot is used, it will run at full x16 speed. GIGABYTE X470 AORUS ULTRA GAMING Socket AM4/ AMD X470/ DDR4/ Quad-GPU CrossFireX Quad-GPU SLI/ SATA IT Reliance Limited. When using more than 1 PCIe slot, the allocated bandwidth will change. and we see the beginnings of something beautiful in three-way CrossFireX as well. 3.0 has twice the bandwidth of 2.0, for most applications the extra bandwidth isn't needed. ![]()
