SAPPHIRE PULSE RX 5700XT – Navi Heartbeat Elevated

Synthetics, Power Draw, and Thermals

Firestrike Extreme

Firestrike is running the DX11 API and is still a good measure of GPU scaling performance, in this test we ran the Extreme version of Firestrike which runs at 1440p and we recorded the Graphics Score only as the Physics and combined are not pertinent to this review.

Time Spy

Time Spy is running the DX12 API and we used it in the same manner as Firestrike Extreme where we only recorded the Graphics Score as the Physics score is recording the CPU performance and isn't important to the testing we are doing here.

Thermals

Thermals were measured from our open test bench after running the Time Spy graphics test 2 on loop for 30 minutes recording the highest temperatures reported. The room was climate controlled and kept at a constant 22c throughout the testing. The default fan curve for the SAPPHIRE PULSE RX 5700XT was much more favorable than in the past where the sound level was prioritized, this time the target is thermals and allows the card to ramp up the fan to maintain the stock 73C thermal target.

Power Draw

Power draw numbers were taken from the total system power draw by measuring with a Kill-A-Watt. We ran Unigine Valley for 30 minutes and observed the highest sustained load. Something to keep in mind when observing total system power draw is that there are times where a GPU simply being faster and requiring more from the CPU can cause the total system power draw to increase with the like of the Core i9-9900K. That said, the total system power draw is still important as it is how much power it is taking to run the system.

WCCFTECH RATING

The SAPPHIRE PULSE RX 5700XT improves in every way over the reference design in thermal and acoustic performance to the point it renders the reference design as an afterthought.

Pros

• Much cooler than the reference model
• Much quieter than the reference model
• Dual bios
• Quick Connect fans
• PCI-e Gen 4.0
• Subtle RGB
• Priced well

Cons

• Low overclocking returns
• No dedicated hardware for Ray Tracing
• Performs inline with reference model frame rates
