AMD claims world-first for PCIe 4.0-ready graphics cards

Believed to be the world’s first PCIe 4.0-ready desktop CPUs and GPUs, the AMD Radeon RX 5700 series graphics cards have been announced, together with third generation AMD Ryzen desktop processors and AMD Ryzen 3000 series processors with Radeon Graphics (APUs) for gaming computers.

The AMD Radeon RX 5700 series graphics cards for 1440p gaming, are built on the new AMD RDNA gaming architecture and 7nm process technology. They are claimed to deliver superior visual fidelity, lightning-fast performance and advanced features to power the latest AAA and eSports titles.

The third generation AMD Ryzen desktop processors have up to 12 cores and 24 threads to deliver the first high-performance 7nm processors in consumer desktop PCs, says AMD. Building on the legacy of high-performance Zen architectures, the Zen 2 microarchitecture incorporates enhancements that deliver a significant IPC uplift of an estimated 15 per cent generationally for faster gaming and content creation.

AMD Radeon RX 5700 Series graphics cards harness the RDNA gaming architecture, which was built for scalability and power efficiency, and designed to power the future of PC, console, mobile and cloud-based gaming. The RDNA architecture supports high-speed GDDR6 memory, provides PCIe 4.0 support, and provides up to 1.25X higher performance-per-clock and up to 1.5X higher performance-per-watt over AMD’s previous Graphic Core Next (GCN) architecture. The result enables “hyper-realistic, ultra-responsive and high-framerate gaming experiences,” says the company.

New features in the Radeon graphics cards include Radeon Image Sharpening (RIS). This brings crispness and clarity to in-game visuals that have been softened by other post-process effects in DirectX 9, 12, and Vulkan titles, explains AMD. When paired with Radeon GPU upscaling, RIS enables sharp visuals and fluid frame rates on very high-resolution displays.

FidelityFX offers an open-source toolkit for game developers with high-quality post-process effects to help make games look beautiful while offering an optimal balance of visual fidelity and performance. Available on GPUOpen, FidelityFX features Contrast-Adaptive Sharpening (CAS), which draws out detail in low-contrast areas while minimising artifects caused by typical image sharpening routines.

Another enhancing feature is Radeon Anti-Lag. This is optimised for eSport and improves competitiveness by decreasing input-to-display response times by up to 31 per cent, according to AMD.
