Video engine - Performance - iSharpening - Anti lag
An improved display and video/media engine
Radeon series 5700 obviously will support FreeSync 2 (Dolby Vision HDR10). Connectivity wise you'll notice that the mini USB connector for VR is not there, that's optional to offer for the AIB partners. But it does confirm what I have been saying a long time, the VR trend has passed. You'll notice HDMI 2.0b support (not 2.1), new is Display Stream Compression which we'll talk a bit more about in the actual review. The media engine has been updated as well, now offering support for H.264 4K150/8K30 Decodes and 4K90 Encodes (that's Ultra HD recording at 90 Hz/PS). For H.265 you'll see 4K60 Decode support, 4K90 Encode support. lastly, Vp9 has become more popular with Youtube and Twitch supporting it and as such, that was bumped up towards 4K60 Decodes.
Performance
I have mentioned it, these cards will perform in that Vega range and slowly replace them. Depending on price it might be an attractive alternative. The Xt is to fight the RTX 2070 from NVIDIA, the non-XT model is positioned against the GeForfce RTX 2060.
AMD Radeon image sharpening
As a bit of mud throwing to NVIDIA, AMD is going to offer a new technology called Radeon image sharpening, and I bet you can get what that does. In complex AA modes that blur stuff a bit (FXAA), you can enable this feature to enhance your image quality at extremely low (FPS)cost. We're talking 2-3 frames per 150 FPS here. Radeon image sharpening is a contrast adaptive sharpening combined with GPU upscaling. To accomplish this, a full frame post-processing shader is used. Vulkan, DX9, and DX12 will be supported initially. This is a NAVI only feature for now. The status on DX11 I do not have an answer for just yet.
Radeon Anti Lag
Here's an implementation that I actually am excited about. At little to no cost you can gain roughly 30% reduction in lag. Really, automatic low latency feature (Radeon anti-lag) is something you might want to look into.
It can bring ou an up-to 32ms decrease in latency. In the driver, the software will precisely slow down the CPU lining (queuing) it up with the output of the GPU, and that will get the response time better in check.
This feature will work best in GPU limit situations like slow GPUs, if you are CPU bound the technology is not going to benefit you. We'll discuss more about this in the Radeon 5700 reviews.
Concluding
That’s it for this preview on the new Radeon RX 5700 and 5700 XT from AMD. On the 7th of the 7th, these products will (should) be unleashed onto the market, and at that timeframe, we may also publish our review. We'll bring it all, performance, technology, power consumption, heat-levels and of course all other good stuff.
At the time of writing (hours before the E3 live stream, we have not received any prices. Logic dictates something in the 379 USD range for the 5700 and 449 USD for the 5700 XT, however, that is what I think it'll be. I'll update to the final prices once they get official and when I get a chance to get back online. More soon.
