AMD Announces Radeon RX 5700 Based on Navi: RDNA, 7nm, PCIe Gen4, GDDR6
AMD at its 2019 Computex keynote today unveiled the Radeon RX 5000 family of graphics cards that leverage its new Navi graphics architecture and 7 nm silicon fabrication process. Navi isn't just an incremental upgrade over Vega with a handful new technologies, but the biggest overhaul to AMD's GPU SIMD design since Graphics CoreNext, circa 2011. Called RDNA or Radeon DNA, the new compute unit by AMD is a clean-slate SIMD design with a 1.25X IPC uplift over Vega, an overhauled on-chip cache hierarchy, and a more streamlined graphics pipeline.
In addition, the architecture is designed to increase performance-per-Watt by 50 percent over Vega. The first part to leverage Navi is the Radeon RX 5700. AMD ran a side-by-side demo of the RX 5700 versus the GeForce RTX 2070 at Strange Brigade, where NVIDIA's $500 card was beaten. "Strange Brigade" is one game where AMD fares generally well as it is heavily optimized for asynchonous compute. Navi also ticks two big technology check-boxes, PCI-Express gen 4.0, and GDDR6 memory. AMD has planned a July availability for the RX 5700, and did not disclose pricing.

Wait and see how well this actually performs in a full, hands on review though.
Anyway, it all matters about price and performance overall, not just this title. It looks like power use will go down to so overall it seems solid (price tho?). It would be great if it was 2070 or better for a cheaper price. Perhaps NVIDIA will drop their prices.
So for AMD its smarter to offer a smaller die size at competitive prices and better power consumption, rather than adding dedicated ray tracing hardware and increasing their die size for no real benefits in actual games.
I expect their RX 3600 to debut at $350, their RX 3700 at $450, their RX 3800(later down the line) for $650, their RX 3500 for $250
RX5700, 2560sp, 2GHz, 195W (compared to Vega64)
4096sp × 1.55GHz ÷ 2560sp ÷ 1.25 ≈ 2GHz
295W ÷ 1.5 ≈ 195W
AMD tested to Strange Brigade which is AMD's DX12 game. For example, in this game RX 570 is faster than GTX 1660. Also RX 580 is same with GTX 1660 Ti. This is certainly AMD's strategy. I think RTX 2060 is faster than RX 5700 in Nvidia's games such as Witcher 3 (also AC Odyssey). I disappointed for AMD's Computex. In addition, I don't like Ryzen 7's 8 cores 16 threads. I hope that AMD will release R7 12 cores 24 threads.
I don't like this gen(Ryzen 2 and RX Navi) maybe i will buy Ryzen 4000.
High end AMD GPU's
RX5700=RTX 2060+%5-10 for 400 Dollars
RX5800=RTX 2070 for 500 Dollars
Med-Low tier GPU's
RX3060=GTX 1650
RX3070=GTX1660
RX3080=GTX 1660-GTX 1660 Ti
(Most games)
I want to know how many transistors it has.
Both 1.25x "IPC" as well as 1.5x power efficiency sound really good, that should bring Navi up to par with Turing, hopefully a little ahead considering it is on 7nm.
We'll have to wait and see.
And the price point is retarded.
As for the no RT... that to me is the most interesting bit of it all, and mostly when thinking about the next consoles. There's a good chance we won't see a same or similar Navi in there, surely they will have to come up with something.
