ROG Strix RTX 5070 12GB GDDR7 Graphics Card

The ASUS ROG Strix RTX 5070 delivers 12GB of GDDR7 memory on a 192-bit bus with an effective 28 Gbps clock. The Blackwell GPU provides 6144 CUDA cores for gaming and AI workloads. It connects through a PCI Express 5.0 x16 slot and supports DirectX 12 Ultimate plus OpenGL 4.6. Four simultaneous monitors are supported at up to 7680 x 4320 resolution.

PCI Express 5.0 x16 Slot and 12GB Frame Buffer

The card occupies a standard PCI Express 5.0 x16 slot and draws power through the motherboard and auxiliary connectors. The 12GB frame buffer frees system memory for other tasks while the 192-bit interface feeds the GPU at 28 Gbps. Two HDMI 2.1b and three DisplayPort 2.1b outputs drive high-refresh displays without adapters. The silver shroud fits typical ATX chassis clearance.

Shin-Etsu X-23-7868-2D Thermal Paste Included

The bundle supplies Shin-Etsu X-23-7868-2D paste rated at 6.2 W/m·k conductivity and 0.07 °C·cm²/W resistance. Its 100 Pa·s viscosity makes application easy and the gray compound remains stable for a suggested two-year cycle. Pre-applied or user-spread, it improves heat transfer between the Ryzen 5 9600X and the ROG Strix B850-E cooler. This reduces thermal throttling risk during sustained loads.

Questions about this item

How long can the RTX 5070 sustain its 28 Gbps memory speed before thermal limits appear?

The 12 GB GDDR7 memory runs at 28 Gbps across a 192-bit bus; sustained loads will hit the GPU thermal ceiling first, so case airflow and the included Shin-Etsu paste become the limiting factors.

What noise and heat levels should I expect when the card runs all day at full load?

The triple-fan ROG Strix cooler is built for the 6144-core Blackwell GPU; expect moderate fan noise and exhaust heat that a well-ventilated chassis can handle without throttling.

Which motherboard socket and power connectors must I already have for this GPU to work?

You need a PCI Express 5.0 x16 slot on an AM5 motherboard such as the ROG Strix B850-E and a power supply with enough 12 VHPWR or 8-pin connectors for the card's rated draw.
