AMD Announces RX 5000 Series Graphics processors at Computex - Demos RX 5700
As we all know NAVI is the new family of Radeon GPUs. NAVI is based on 7nm RDNA architecture (Radeon DNA). NAVI will be PCIe Express 4.0 compatible, has a new compute design, new cache-hierarchy and will be reducing latency, lower power. 1.25x perf per clock improvement and 1.5x better power consumption.
During the keynote speech AMD announced the and named the 7nm NAVI based graphics cards the Radeon RX 5000 series products. A card based on NAVI was shown in a live demo and compared against a GeForce RTX 2070 in a direct comparison with the Radeon RX 5700. Strange Brigade. The FPS looked about the same but was mentioned to be roughly 10% faster.
AMD considers Navi as a completely new architecture. No longer GCN, but RDNA. RDNA uses completely redesigned Compute Units, which should significantly increase per-clock performance and efficiency. This includes a new cache structure. The changes are expected to boost Vega's performance by at least 25 percent per cycle ("IPC") and increase efficiency (wattage) by at least 50 percent.
Raytracing was not mentioned in the presentation and the Navi cards do not seem to have any hardware support for it. According to AMD, the Navi architecture will serve as the foundation for video cards for gamers in the coming years. AMD has not yet published any specifications or prices for the cards in the RX 5000 series. The manufacturer will do this during the E3 game fair, via a live stream. AMD announces that NAVI will be launching in July. June 10th there will be a live stream with all details on products, specs and prices.
Navi will debut as Radeon RX 5000 series, with the Radeon RX 5700 series leading initially.

It actually was slightly faster ~10% than the 2070. That being said Strange Brigade is heavily AMD favored.. this being a new architecture might change that but until I see another game I'm going to assume the card they showed will be around 2070 performance in other games.
Still pretty cool that it's a new architecture tho
What is interesting if true is the 1.5x better power consumption. Performance wise Vega was not that bad. I mean the Vega 56 was just as good as the 1070. The main problem was power consumption and temp (and selling at the same price as nVidia while releasing the card at a later date). If they can address the power consumption and release something in the neighbourhood of the 2080 and 2070 while undercutting nVidia (and forcing them to adjust the price) then i'll be more than happy.

vega56 was better than the 1070 - thats entirely why nvidia released the 1070ti. but yes, power consumption was pretty damn bad for vega, even if undervolted
im half irritated that i have to wait until E3 for actual architecture & model-specific details, but its not that far away

Didn't you guys see that PCIE4.0 3DMark benchmark????
69% better performance over a 2080Ti????
That can't be right, just from a bandwidth upgrade? Going from PCIE2.0 to PCIE3.0 wasn't much different, defo not 69%!??

It's a benchmark designed to saturate the pci-e bandwidth... there aren't going to be any games in the next 10 years that come close to doing that.
There have been synthetic examples of this with prior PCI-E specs.
