AMD Radeon RX 5700 : Hands On + Key Features
The AMD Radeon RX 5700 Hands On!
Its 8 GB of GDDR6 memory runs at a speed of 1750 MHz, giving it a peak memory bandwidth of 448 GB/s.
Because the AMD Navi GPU is fabricated on the 7 nm process technology, the whole card only need 185 watts of power.
AMD RDNA Architecture
The AMD RDNA architecture offers these advantages over the older GCN architecture :
- New Compute Unit and SIMD design that delivers 1.25X better performance per clock
- New multi-level cache hierarchy for reduced latency and power
- Adds support for GDDR6 memory and PCI Express 4.0
- New Radeon Media Engine with 4K encode and 8K decode capability for VP9, H.264 and HEVC
7 nm Process Technology
A key advantage the AMD Navi GPU has over the previous AMD Vega GPU is the finer 7 nm process technology it uses.
This change alone lets the AMD Navi deliver 50% more performance per watt than the AMD Vega.
