AMD’s Radeon RX 7000 series has arrived and working hardware is now in AMD’s labs. During the Ryzen 7000 launch event, AMD demonstrated a working pre-release build of his RDNA 3 GPU aka Navi 3x aka RX 7000. P’s lie (opens in new tab)(Jump to 30:48 in the video above if the embed doesn’t do it automatically.) Of course you know exactly that. none No one else has the game, so I can’t run benchmarks or say how it will perform on competitive GPUs. Still, RDNA 3 is inside the house.
It’s shaping up to be an exciting fall for anyone looking to upgrade to one of the best graphics cards out there, as they should be getting new Nvidia Ada RTX 40-series GPUs alongside AMD’s RDNA 3 offering. It’s a safe bet that the graphics card will launch first, but so far no one knows who will come out on top.
The latest rumors and performance leaks suggest that RTX 40-series cards are about to ship, as it looks like people who are likely working for major add-in card partners will also have hardware. AMD’s RDNA 3, on the other hand, has only been demonstrated in very limited ways on AMD’s stage. This is “one more thing of him” that AMD CEO Lisa Su likes to throw in at the end of his presentation.
History has shown that when AMD shows off its upcoming GPU as ‘the other’, it’s usually 3-6 months away. However, Su did say that his RDNA 3 is coming “later this year.”
AMD’s demo ran at 4K and ultra settings and it looked smooth, which is also not very telling. We’d expect a 50% or more performance improvement on the , but we’re not too sure about that either.
According to the GPU benchmark tier, the RX 6900 XT consumes 308W of power and delivers 130 fps at 1080p ultra, 106 fps at 1440p ultra and 63 fps at 4K ultra. The lower tier RX 6700 XT uses 215W and consumes an average of 96 fps, 71 fps and 39 fps, while the RX 5700 XT consumes 214 W and consumes 74 fps, 53 fps and 29 fps at the same resolution provide. Doing the math, the 6900 XT improves performance per watt by 22% to 50%, while the 6700 XT only improves by 29% to 34%.
As always the devil is in the details and we’ll have to wait for RDNA 3 hardware to launch to determine exactly how good it is compared to its predecessor. , which ultimately translates to “up to 50% more performance per watt,” but this is only a limited comparison. For example, for 4K Ultra or picking a GPU to compare.
Similar to Nvidia’s RTX 40 series, we expect AMD to be the first to launch higher performing and higher priced variants. However, RDNA 3 also uses his 5nm GPU chiplet. This means that AMD’s highest performing solution could consist of multiple chiplets, possibly launching mid-range products at the same time. Meanwhile, what AMD intends to do with its “GPU chiplets” is still under investigation.
AMD uses Ryzen CPUs with central IO chiplets that connect to memory, PCIe, and other interfaces. This, for the Ryzen 5000 series, is manufactured on his 12nm process of the previous generation. This is fine because external interfaces typically don’t scale well on small nodes. The CPU chiplets will then be manufactured on his 7nm (soon 5nm) process node connected to his IO chiplets via AMD’s Infinity Fabric. Can AMD do something similar with their GPUs? Maybe, or go in a completely different direction.
One rumor floating around is that AMD will use a memory interface chiplet. The idea is to move all his GDDR6 controller to a chiplet…then link it to the main GPU via Infinity Fabric. We’re not entirely sure what the benefits of that would be, as each chiplet would require Infinity Fabric, but we’ll see what exactly AMD has planned for the next few months.
According to Lisa Su, the unnamed RDNA 3 GPU (probably the top model, but I’m not sure) was running Lies of P at 4K and Ultra settings. She also said, “I’m very happy with how RDNA 3 looks in the lab and I can’t wait to tell you more about it when it launches later this year.” We are also looking forward to it, but it looks like we have to wait a little longer.
