SAPPHIRE PULSE AMD Radeon RX 6600 XT The SAPPHIRE PULSE AMD Radeon RX 6600 XT Graphics Card runs on the powerful Dual-X Cooling Technology coupled with Intelligent Fan Control to keep temperatures low and fan noise low. The refined PCB design delivers stable, reliable, and steady performance, which efficiently lowers PCB temperature and component signal noise. THE ULTIMATE GAME CHANGER Powerhouse Performance for 1080P Gaming Engine Clock Boost Clock: Up to 2593 MHz Game Clock: Up to 2382 MHz Boost Clock is the maximum frequency achievable on the GPU running bursty workload. Boost clock achievability, frequency, and sustainabilty will vary based on several factors, including but not limited to: thermal conditions and variation in application and workloads. Game Clock is the expected GPU clock when running typical gaming applications, set to typical TGP(Total Graphics Power). Actual individual game clock results may vary.
