Sapphire’s PURE Series Graphics Cards: Design and Cooling
Design and Cooling Details
The tested samples, provided by AMD and Sapphire, include the PURE Radeon RX 9070 XT and RX 9070. The PURE series by Sapphire is noted for its small overclocking capabilities right out of the box. Both graphics cards share a distinct white and mecha-style design, with identical cooling designs, fan counts, and overall dimensions. The cards are identically 3 slots thick and support 2 groups of DisplayPort 2.1a and HDMI 2.1 each. The aluminum alloy backplate enhances structural integrity and heat dissipation.
The integrated heat dissipation module features 5 composite thermal conduits, extending beyond the PCB to cover the GPU, GDDR6 memory, and VRM power supply. The Honeywell PTM7950 phase-change thermal interface material ensures efficient heat transfer between the heat sink and GPU. The fan setup, with 1 medium and 2 large-size AeroCurve fans, optimizes airflow efficiency by reversing the central fan, minimizing airflow conflicts.
The PCB is a robust 12-layer board with 2 oz copper foil, occupying about 60% of the total card length, leaving ample space for heat dissipation. The power terminal includes 2 sets of PCIe 8-pin inputs and an ARGB terminal compatible with the motherboard for RGB lighting control.
Performance Benchmarks: Comparing the Competition
3DMark Testing
The testing platform employed the AMD Ryzen 7 9800X3D processor, with comparisons against the GeForce RTX 5070 and 5070 Ti. In benchmarks like Time Spy and Time Spy Extreme (DirectX 12 games), the RX 9070 XT outperformed the higher-priced RTX 5070 Ti by 6%, while the RX 9070 surged 18% ahead of the comparably priced RTX 5070. In the Steel Nomad heavy load test, directX 12 mode showed a 4% lead, while Vulkan tied between the RX 9070 XT and the test opponents.
