Much is known yet little has been shown for Intel's Xe-based HP 1T and 2T graphics cards, until now that is as they have been photographed.
Intel's Xe HP units basically consist out of three variants, you know it already, but 1 tile, 2 tiles, and 4 tiles, basically each tile is a GPU package which is then connected through covers technology from intel (mich like what HBM seated onto a GPU package. Each tile has 512 execution units. The base tile is manufactured using Intel’s 10nm SuperFin architecture. Earlier on these products were revealed to be codenamed 'XeHP HD Graphics Neo', we know it as Arctic Sound. The 1-tile variant physically has 512 EUs, the 2-tile variant will have 1024 EUs and the model with the highest specs with 4 tiles will get 2048 EUs.
In the 1T photo that Igor's Lab posted you'll see paired 16 GB of HBM2E memory with 716 GB/s memory bandwidth. An interesting fact is that a single tile has 384 out of 512 EUs enabled (3072 shaders), meaning it's reduced. The card has a typical board power of just 150 W. The 2T card is much beefier looking, larger than a 2-slot card, and lengthy passing 28 cm. The 2T card uses a 2-tile GPU (hence the 2T suffix), however here 480 out of 512 EUs are enabled. This maths towards 7680 shaders processors. The dual-chiplet design then gets 32 GB of HBM2E memory 2 tiles x 16 GB TDP is doubled up to 300 W.
- Intel Xe HP 1-Tile GPU: 512 EU [4096 Cores, 12.2 TFLOPs assuming 1.5GHz, 150W]
- Intel Xe HP 2-Tile GPU: 1024 EUs [8192 Cores, 20.48 assuming 1.25 GHz, TFLOPs, 300W]
- Intel Xe HP 4-Tile GPU: 2048 EUs [16,384 Cores, 36 TFLOPs assuming 1.1 GHz, 400W/500W]
It will be interesting to see if Intel would ever go for a 4T model for the consumer parts, but we seriously doubt that due to many complexities, the first being power consumption. The cards have a PCIe Gen4 interface. See photos below.
