The AMD Radeon RX 5700 Hands On!
The AMD Radeon RX 5700 (US | UK | MY) has an AMD Navi GPU with 2304 stream processors. This gives it 144 TMUs and 64 ROPs, delivering a peak output of 248 GT/s and 110 GP/s.
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 new RDNA architecture replaces the GCN (Graphics Core Next) architecture that powered the Vega 64 and Vega 56 cards.
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.

The AMD Radeon RX 5700 (US | UK | MY) uses a cut-down version of the AMD Navi, and requires only 185 watts of power. You will need a power supply with a 6-pin and an 8-pin PCI Express power cables.
