The Radeon E8870 PCIe was a mobile graphics chip by AMD, launched on September 29th, 2015. Built on the 28 nm process, and based on the Saturn graphics processor, in its Saturn ES8870 variant, the chip supports DirectX 12. This ensures that all modern games will run on Radeon E8870 PCIe. The Saturn graphics processor is an average sized chip with a die area of 160 mm² and 2,080 million transistors. Unlike the fully unlocked Radeon R9 M280X, which uses the same GPU but has all 896 shaders enabled, AMD has disabled some shading units on the Radeon E8870 PCIe to reach the product's target shader count. It features 768 shading units, 48 texture mapping units, and 16 ROPs. AMD has paired 4 GB GDDR5 memory with the Radeon E8870 PCIe, which are connected using a 128-bit memory interface. The GPU is operating at a frequency of 1000 MHz, memory is running at 1500 MHz (6 Gbps effective). Being a single-slot card, the AMD Radeon E8870 PCIe does not require any additional power connector, its power draw is rated at 75 W maximum. Display outputs include: 4x DisplayPort 1.2. Radeon E8870 PCIe is connected to the rest of the system using a PCI-Express 3.0 x16 interface.
