The Radeon RX 5700 It is available online for around €450.
Card Features
RX 5700 XT card is an AMD card based on a brand new architecture: RDNA. This architecture is characterized by the implementation of an efficient, but economical system (increasingly lower electricity consumption). The 5000 Series GPU delivers 1.5x more efficient performance per watt than the previous generation and 2.3x better performance per watt. Thus, the RDNA architecture allows 50% more energy efficiency compared to the GCN architecture of the previous Radeon RX Vega. The RDNA-based Navi 10 GPU has 10.3 billion transistors . For comparison, the Vega 64 has 12.5 billion transistors while Nvidia's TU106 has 10.8 billion.
7-nanometer etching procedure . AMD has abandoned HBM2 memories to focus on DDR6 memories. HBM2 memories are efficient but are very expensive and difficult to design. The 7 nm engraving technique allowed the Navi 10 chip to be quite compact: 251 mm 2 instead of 495 mm 2 for the Vega 64. It also beats Nvidia's TU106 chip on 2000 series cards in density , because the latter occupies 445 mm 2 .
The Radeon RX 5700 XT card features 2,560 compute units , 64 render units , and 160 texture units . This card consumes 225 Watts. It consumes less than the GeForce RTX 2070 Super which needs 235 Watts to operate. power supply block recommended for a PC hosting the Radeon RX 5700 XT would be 600 Watts.
8 GB DDR6 memory operating with a base frequency of 1.605 GHz on the 256-bit memory bus. The GPU thus has a bandwidth of 448 GB/s. The transistors integrated in the GPU switch with a boost frequency of 1.905 GHz in boot clock. AMD introduces with the RDNA architecture a new concept of frequency called gaming frequency or Game Clock. The RX 5700 XT has a gaming frequency of 1.755 GHz.
In terms of design, the card has a sober and compact look. It does not include an RGB LED system. This card measures 29.3 x 19.1 x 6.9 centimeters and weighs approximately 1.25 kg. It uses a PCIe 16x 4.0 interface, which is new. Indeed, the previous generation uses PCI 3.0 standards.
Card performance
The RX 5700 XT manages to reach 1.905 GHz . It thus beats the Radeon VII which stagnates at 1.8 GHz. The 50% jump in energy performance is mainly due to the new 7 nanometer engraving technique, the new RDNA architecture and the optimizations made to the Ryzen CPU. AMD manages to produce a graphics card at a reduced price thanks to the switch from memory to GDDR6. The company no longer uses either GDDR5 or HBM on new generation memory cards.
This architecture does not yet benefit from Ray tracing: it is still too early according to David Wang, Head of AMD's Radeon Division. On the other hand, AMD is already planning to design the so-called Next Gen RDNA which supports Ray tracing technology.
The new Navi 10 manages to provide 8K HDR video display at 60 FPS or 4K at 240 FPS via its DisplayPort output.
Different features provide a high-performance system and sharper graphics rendering, to name only Image Sharpening, Local Streaming and Radeon Anti-Lag.
Image Sharpening is AMD's answer to Nvidia's DSLL. This is a post-processing effect that allows images to be displayed sharper. This allows you to have a graphic rendering comparable to 4K even if the resolution used is WQHD. The result is quite surprising with a negligible frame rate loss of less than 1.5%.
Local Streaming consists of being able to play PC games on Apple TV or Android TV . The Radeon Link allows for easy linking between your PC and TVs. AMD Radeon Relieve lets you capture, relive your gaming highlights and share them with your community. Playing and sharing has never been easier.
As for Radeon Anti-Lag , it consists of properly timing the rate of data processing at the GPU input and reducing latency. It allows more synchronous and coherent work between the CPU and GPU, thus reducing processing wait time as much as possible. Radeon Anti-Lag allows the system to be more responsive to gaming.
Benchmarking of the RX 5700 XT
The RX 5700 XT scores 16,713 on G3D Mark. This is slightly lower than that of the GeForce RTX 2070 SUPER, the latter obtaining a score of 18,117, or a performance of 8.4% more. The RX 5700
On 3DMark, the RX 5700
When testing the RX 5700 XT on Fornite, we obtained an average frame rate per second of 245 FPS in 720p resolution. In high 1080p resolution, the card provides 125 FPS. The frame rate per second is 77.5 in QHD 1440p and 28.5 FPS in 4K resolution.
In short, the RX 5700 It is even more economical and displays good performance in WQHD. The only negative point is the fact that this card does not yet support Ray tracing. The Image Sharpening provided by AMD nevertheless makes it possible to fill this gap. The RX 5700 XT is available online for around €450.
