Introduction

Sapphire Logo

The Sapphire Radeon RX 6600 XT Pulse OC is the company's value-oriented custom-design card based on AMD's latest performance-segment GPU, with the other performance-oriented card from the brand being the NITRO+. The new RX 6600 XT is designed for the vast majority of gamers still playing at the Full HD (1080p) resolution with maxed out details, including real-time raytracing. It's cut from the same RDNA2 cloth as the rest of the RX 6000 series. Sapphire pairs this with a low-noise optimized cooler and specifications closest to AMD reference, which means the card can be priced closest to the $379 baseline set by AMD.



The RX 6600 XT marks the debut on the "Navi 23" silicon to the DIY desktop space. The tiniest silicon based on the RDNA2 graphics architecture, it still packs a mean feature set that includes 2,048 stream processors, 32 Ray Accelerators for real-time raytracing, 128 TMUs, 64 ROPs, and 8 GB of standard memory. This, however, is across a narrow 128-bit GDDR6 memory bus. AMD is running the memory at 16 Gbps (GDDR6-effective) and combining it with 32 MB of Infinity Cache on-die memory.

The Sapphire RX 6600 XT Pulse OC features a simple aluminium fin-stack cooler with a two-slot thick, dual-fan design. It also comes with a metal backplate. Some of the airflow from the cooler vents through the card and out the backplate. The Pulse OC features a negligible factory overclock to 2593 MHz, compared to the 2587 MHz reference, and Sapphire is pricing the card at $399, a $20 premium over the steep $379 starting price of the RX 6600 XT.
