Intel’s high-performance Xe graphics cards codenamed “Alchemist” are slated to arrive in the first half of 2022. The Xe-HPG lineup will face off against the GeForce RTX 3070/3070 Ti and the Radeon RX 6700 XT in the high-end and the GTX 1650 series in the budget range. The top-end SKU will pack 512 Execution Units, with a boost clock of 2.1GHz. It’s unclear what exactly an EU in Geekbench refers to. It could be an 8 shader cluster or a 16 shader Xe Core which constitutes the Xe-HPG architecture.
The graphics memory of 12.7GB is likely an error. We’re likely looking at an 8GB or 12GB discrete memory paired with a 256-bit bus. 14Gbps GDDR6 memory connected via a 256-bit bus results in a bandwidth of 448GB/s, the same as the Radeon RX 6800 XT/6900 XT and the GeForce RTX 3070. The boost clock of 2.1GHz makes sense and falls in line with what TSMC’s N6 process node is capable of. We might even see boost clocks close to the 2.5GHz close to the launch.
