Recently, media reports that Intel Xe architecture discrete graphics card will use tiled small chip stacking design ideas, each tile has 128 execution units (EU), and each unit has 8 cores, four-chip structure has 4096 cores, but power consumption of up to 400W or even 500W.
It’s definitely crazy. You know, NVIDIA, AMD graphics card now up to 4608, 4096 cores, corresponding to power consumption 280W, 295W. While the core of the three different architectures is not directly comparable, it’s not too far away, and Intel’s energy efficiency can’t be so low.
Sure enough, it flipped quickly. WCCFTech’s search for the latest intelligence from internal informants is far more shocking.
We know that the Intel Xe architecture is for everything from thin notebooks to high-performance computing and is divided into three different sub-architectures, from low to high for low-power Xe LPs, high-performance Xe HP, and High Performance Computing Xe HPC.
WCCFTech claims that the Xe LP architecture is 128 execution units per watt, with an internal number Xe 12.1, and the Xe HP architecture is Xe 12.5, with 512 execution units per watt.
Xe HP is divided into three different specifications:
– Single watt: a total of 512 execution units, 4096 cores, power consumption of about 150W, core frequency 1.5GHz, floating-point performance 12.2TFlops
– Dual tiles: total 1024 execution units, 8192 cores, power consumption of about 300W, core frequency 1.25GHz, floating-point performance 20.48TFlops
– Four-watt: a total of 2048 execution units, 16384 cores, power consumption of about 400/500W, core frequency 1.1GHz, 36TFlops
What kind of concept is this? NVIDIA’s top Titan RTX single-precision floating-point performance is also only 16.3TFlops, AMD RX Vega 64 is only 12.66TFlops, Intel is 2.2 times, 2.8 times their!
The specifications of the top Xe HPC are not yet known, but they are bound to go further.
