Intel suspends commercial production of Xe HP which evolved into production path on the 28th of October 2021

Intel’s Xe-HP compute GPUs were the company’s first high-performance discrete GPUs in years to power on and were the first standalone Xe GPUs that Intel demonstrated to the public. But these GPUs will never make it to the market as the company decided to abandon this lineup. Instead, according to a tweet from Raja Koduri, senior vice president and general manager of the Accelerated Computing Systems and Graphics (AXG) Group at Intel, the company will concentrate on its Xe-HPG and Xe-HPC GPU families.
We deployed Xe HP in our oneAPI devcloud and leveraged it as a SW development vehicle for oneAPI and Aurora. We currently don’t intend to productize Xe HP commercially, it evolved into HPG and HPC that are on general market production path October 28, 2021
The Xe-HP Family Axed
“We deployed Xe-HP in our oneAPI devcloud and leveraged it as a software development vehicle for oneAPI and Aurora,” said Koduri. “We currently don’t intend to productize Xe-HP commercially, it evolved into HPG and HPC that are on general market production path.
When Intel detailed its Xe family of GPU architectures in August 2020, it unveiled four architectures that were meant to power four product facilities: the Xe-LP for integrated and low-end discrete GPUs, the Xe-HPG for high-performance gaming graphics cards, the Xe-HP for commercial data center GPUs, and the Xe-HPC for supercomputers.
Xe-HP GPUs were meant to scale from one GPU tile to four GPU tiles and were supposed to power everything from cloud gaming to video streaming platforms and from virtual desktop infrastructure (VDI) to commercial accelerated computing.
To show off the potential of its Xe architecture in high-performance implementations, Intel demonstrated a quad-tile Xe-HP GPU in August 2020. That early Xe-HP GPU outperformed Nvidia’s A100 compute GPU by double and offered performance of around 42 FP32 TFLOPS. The silicon was made internally using the company’s 10nm Enhanced SuperFin (now called Intel 7) fabrication process, the same node that is used to make Intel’s Alder Lake and upcoming Sapphire Rapids processors.
Intel’s Xe-HP architecture relies on specialized execution units (EUs), high-bandwidth internal interconnects, and an HBM2E-based memory subsystem since these GPUs are (or rather were) designed to process vast amounts of data. These EUs support data formats and instructions common for data centers and high-performance computing (HPC), which includes FP64 for technical computing, bfloat16 for AI/ML workloads, DP4A convolution instruction for DL, and Intel’s new XMX instructions. In addition, Xe-HP has advanced media encoding/decoding capabilities to address video streaming services.
Missed Window of Opportunity?
Given the fact that Intel received its first Xe-HP GPUs from the fab in April 2020 and showcased them publicly in August, it probably planned to commercialize them by now. The company made its Xe-HP GPUs available to software designers back in November 2020 and earlier this year it shipped samples of these compute GPUs to developers.
Quite naturally, the company didn’t disclose why it decided not to roll out its Xe-HP commercially, but we can speculate both about technological and strategical reasons.
Configurations of Intel’s Arctic Sound 2T samples for developers only included cards with up to 960 EUs over two tiles that were rated for 300W, which did not seem like the best combination of performance and power consumption.
While the FP32 performance of Intel’s quad-tile Xe-HP looks impressive today, we do not know anything about its performance in other workloads and how it compares to the performance of existing hardware. Meanwhile, this product must be competitive for at least a couple of years and this is something that cannot be guaranteed given the fact that AMD is about to roll out its next-generation compute GPUs in November, whereas Nvidia is rumored to release its next-gen compute GPUs in 2022.
Timing may not be Intel’s only problem with its Xe-HP GPUs. Back in the day, Intel addressed video streaming platforms like YouTube with Xeon processors or even special Visual Compute Accelerators (based on Xeons). Google’s YouTube is replacing Intel’s Xeon-based machines with servers running its homegrown visual (trans)coding units (VCUs), which could greatly shrink the addressable market for Intel’s Xe-HP GPUs meant to replace Xeons and VCAs. If other major video streaming platforms follow the suit, the media transcoding capabilities of Xe-HP GPUs will hardly be appreciated. Meanwhile, media transcoding has always been a very important Xe-HPC component.
