Intel Arc “Alchemist” PCB Closeup Shows Up on Intel Graphics Discord

Intel put out a clear, close-up picture of its Arc “Alchemist” gaming graphics card engineering sample. This matches with a picture of the PCB rear shot that surfaced in a report by “Moore’s Law is Dead.” The picture reveals a PCB that’s about 3/4th the length of the cooling solution, with the remainder of the cooler’s length being used to directly vent airflow from the back.

The PCB reveals a rectangular pad for the GPU, which corresponds with that of the larger “Alchemist” GPU. This is surrounded by what look like eight GDDR6 memory pads for a 256-bit wide memory interface; at least 10 VRM phases of an unknown configuration; and a power input configuration that’s made up of one each of 8-pin and 6-pin PCIe power connectors (capable of delivering 300 W including slot power). The PCB shows traces that connect the GPU to all 16 PCI-Express lanes of the PCIe finger. Display outputs include three full-size DisplayPorts and an HDMI. This particular variant of “Alchemist” is rumored to feature 512 execution units (4,096 unified shaders), and at least in SiSoft SANDRA, it allegedly outperforms the GeForce RTX 3070 Ti “Ampere.”
