Radeon RX 5700 8GB for 1440p gaming

The ASRock Challenger D 8G OC uses the AMD Radeon RX 5700 core built on a second-generation 7nm process with RDNA architecture. It provides 8GB of 256-bit GDDR6 memory running at 14 Gbps and 2304 stream processors. PCI Express 4.0 support and DirectX 12 compatibility suit modern 1440p gaming builds. Outputs include three DisplayPort 1.4 and one HDMI 2.0b for up to four displays.

Upgrade from older 1080p cards

Moving to this card from a 1080p-class GPU adds the memory bandwidth and compute needed for higher resolutions and refresh rates. The jump is worth it when your monitor exceeds 1080p or when titles demand more than 4GB VRAM. Base frequency sits at 1515 MHz with gaming frequency up to 1675 MHz and dynamic speedup up to 1750 MHz. A 600W power supply and two 8-pin connectors are required.

Dual-slot fit with standard power

At 281 x 137 x 42mm the card fits most mid-tower cases and uses a conventional dual-slot bracket. Installation follows the usual PCIe x16 seat and two 8-pin power cables; a quick installation guide is included. Common issues are forgetting the second power connector or using a PSU below the 600W recommendation. Ensure the case has clearance for the 281mm length before ordering.

Questions about this item

Will the 281 x 137 x 42 mm card fit in my case?

The card measures 281 mm long, 137 mm wide and 42 mm thick. Check your chassis clearance against those dimensions and ensure two 8-pin power cables can reach the connectors.

What is the correct way to seat the PCIe 4.0 x16 card and attach the two 8-pin power plugs?

Align the gold edge connector with the motherboard PCIe 4.0 slot, press down until the retention clip clicks, then firmly connect both 8-pin power cables from the PSU; forgetting either plug will prevent the card from starting.

When should I replace the thermal paste on the RX 5700 GPU?

Re-paste if temperatures rise noticeably after a few years or when you disassemble the cooler for cleaning; use a pea-sized dot of non-conductive paste on the 2304-stream-processor die.
