AMD’s new Navi graphics offers up to 10.14 TFLOPS of power


AMD has set a new benchmark for desktop graphics with the new Navi GPUs. Based on the new 7nanometer RDNA gaming architecture, which has been designed to take care of the diverse gaming workloads, the new GPUs like the Ryzen 3 chips support the PCIe 4 interface.

The first crop of Navi GPUs include Radeon RX5700 and RX5700XT, and the more powerful of the lot can muster up to 9.75 TFLOPS (teraflops) of power, 8GB of DDR6 RAM and can deliver 1440p gaming for a superior visual experience over 1,080p resolution gaming available in RX Vega 56 graphics. According to benchmarks showed by AMD at the event, the RX5700XT can muster slightly more frames per second than Nvidia RTX 2070 at 1,440p and was able to deliver 5% better performance in Ubisoft’s Far Cry: New Dawn and 22% better performance in EA Sports’ Battlefield 5.

The RX 5700 will retail at $379 while the RX5700XT will cost $449.

To celebrate their 50th anniversary, AMD has got an anniversary edition of Radeon RX 5700 XT. It offers 10.14 TFLOPS of power and costs $499.

The key highlights of Navi GPUs include the new compute unit design which offers 2 times faster instruction rate and multi level cache for low latency and lower power consumption. It also supports Ray Tracing, a process which traces the path of individual light rays in a 3D scene. To reproduce the reflection, refraction or shadow formed during games, Ray Tracing needs graphical power.

David Wang, SVP Radeon Technologies Group, pointed out, Ray Tracing is not a new technology for AMD as they have been doing it for years now. Real time Ray Tracing is the next level but quite possible by leveraging the power of cloud computing. In future this will allow people to run games with Ray Tracing on any device.

RDNA will not mark the departure of it’s predecessor GCN as AMD intends to keep it alive as a dedicated hardware for machine learning.

The Radeon RX 5700XT has been designed for better thermal experience. On the top is the new aluminum alloy shroud with acoustically tuned contour design for optimised air flow, while under the hood there vapour chamber cooling and a heat diffusion system made of graphite.

According to benchmarks showed by AMD, the RX5700XT was able to offer 22% better gaming performance at 1,440p over Nvidia RTX 2070.

Besides the new GPUs, AMD announced a bunch of new software based technologies like Radeon Image Sharpening, Fidelity FX and Radeon Anti Lag.

Fidelity FX is an open source image quality toolkit, which allows developers to upscale game graphics at a low cost of development using CAS (contrast adaptive sharpening).

Radeon Anti lag is an optional tool for users which improves click to response rates in games by 31%.

The new Radeon GPU also supports Radeon FreeSync 2 HDR, an open source version of HDR. It can muster 8k HDR at 60HZ and 4K HDR at 120HZ. Asus is expected to launch monitor based on Radeon Freesync 2 HDR.
