Updated: Intel Cans Xe-HP Server GPU Products, Shifts Focus To Xe-HPC and Xe-HPGby Ryan Smith on November 1, 2021 10:30 PM EST
In an additional tweet posted over the weekend by Raja Koduri, the Intel GPU frontman confirmed that Intel will be bringing products based on their Xe-HPG architecture to the server market.
We leveraged Xe HP to build developer ecosystem for HPC, AI and Visual cloud. It’s being used on-site at Argonne and other customers.— Raja Koduri (@Rajaontheedge) October 30, 2021

Painting very broad strokes here from a 280 character announcement, it sounds like Intel will take a very similar tack as NVIDIA for their initial generation of products. That means offering Ponte Vecchio (Xe-HPC) for HPC and high performance AI training, while using the Alchemist (Xe-HPG) products for less intense/more scalable tasks such as AI inference and server-based graphics. All of which leaves me even more curious if Intel has retained Xe-HP’s tile capabilities for Xe-HPG.
With his tweet, Koduri also included a slightly updated version of one of Intel's Xe-HPG slides, which now includes the server graphics role.
Original Story (10/29):
In a tweet published yesterday afternoon by Raja Koduri, Intel’s SVP and GM of the Accelerated Computing Systems and Graphics (AXG) Group, the GPU frontman revealed that Intel has dropped their plans to bring their Xe-HP series of server GPUs to the commercial market. Citing that Xe-HP has evolved into the Xe-HPC (Ponte Vecchio) and Xe-HPG (Intel Arc) families within Intel’s GPU group, the company seemingly no longer sees a need to release a second set of server GPUs – at least, not something based on Xe-HP as we know it.
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— Raja Koduri (@Rajaontheedge) October 28, 2021
Also known by the codename Arctic Sound, Intel’s initial family of server GPUs has been the most visible product under development from Intel’s reborn GPU group. Koduri frequently showed off chips housing the silicon as it was brought-up in Intel’s labs. And, Xe-LP/DG1 excepted, this was the first high-performance Xe silicon that Intel developed. Notably, it was also the only high-performance Xe silicon slated to be manufactured by Intel; Xe-HPC’s compute tiles and Xe-HPG dies are both being built by TSMC.
We haven’t heard much of Xe-HP this year, and in retrospect that was a sign that something was amiss. Still, as of year Intel had been showing off Xe-HP demos with performance as high as 42 TFLOPS of FP32 throughput. And in November the company announced that Xe-HP was sampling to select customers.
But, as it would seem, Xe-HP just isn’t meant to be. For 2021 Intel has been focused on getting Ponte Vecchio assembled for the Aurora supercomputer (and eventually other customers), as well as bringing up the Xe-HPG Alchemist GPU family for Q1 of 2022. According to Koduri, Xe-HP has been leveraged as a development vehicle for Aurora and Intel’s oneAPI – so it hasn’t gone unused – but that’s as far as Xe-HP has made it.
For now, the cancellation of Xe-HP raises some big questions about Intel’s server GPU plans. Xe-HP was intended to be the backbone of their server efforts, utilizing a scalable design that could range from one to four cores to serve datacenter needs ranging from compute to media processing. Between Xe-HP and Ponte Vecchio covering the very high end of the market (e.g. HPC), Intel was slated to develop a potent slate of parallel processors to compete with market-leader NVIDIA, and offer traditional Intel customers a GPU option that let them stay in Intel’s ecosystem.
At this point it’s not clear what will fill the void left by Xe-HP in Intel’s product stack. Ponte Vecchio is in production now, and judging from Intel’s revised Aurora figures, is performing better than expected. But the massive chip is expensive to build – at least in its current configuration. And while Xe-HPG could be called up for server use next year, unless Intel is able to tile it like Xe-HP, they won’t be able to offer the kind of performance that Xe-HP was slated to deliver.
Equally nebulous is a full understanding of why Intel opted to cancel Xe-HP. With the silicon already up and running, canceling it certainly sets back their server GPU plans. But as AMD has already begun rolling out their new CDNA2 architecture-based server GPU products, and NVIDIA is likely aiming for some kind of refresh of their own in 2022, there’s certainly the question of whether Xe-HP was simply too late and/or too slow to compete in the server market. Coupled with that, it’s the only lineup of high-performance Xe parts that Intel was fabbing themselves, using the 10nm Enhanced Superfin process (now referred to as Intel 7).
In any case, Intel is clearly not giving up on their plans to break into the server GPU market, even if pieces of that plan now need to be rewritten. We’ve reached out to Intel for additional details, and we’ll update this story further if Intel releases a more detailed statement on their server GPU plans.

coburn_c - Friday, October 29, 2021 - linkThey've made no progress with any of their GPU designs. Time to throw the Intel GPU on the pile with their smartphone aspirations and Itanium.
Flunk - Friday, October 29, 2021 - linkThey don't have much choice, then need better iGPUs to compete and buying Nvidia is no longer an affordable option. The dGPU ambitions are just a sideshow right now.
Makaveli - Monday, November 1, 2021 - linkI always wonder how things would have been different if it was Intel that bought ATI. And what would the market look like now...
tipoo - Wednesday, November 3, 2021 - linkMight look at Altera or Mobileye for an idea...They're still going, but not really benefitting from the mothership.
MonkeyPaw - Friday, October 29, 2021 - linkI think I read somewhere that the pricing on their desktop GPUs will be in the same highway robbery territory as AMD and NVIDIA. And Intel has been promising a discreet GPU since at least Larrabee, back in 2008. At least their IGPs are finally advancing again, after several generations of stagnant “HD Graphics” editions.
drexnx - Friday, October 29, 2021 - linkand before that, i740 back in 1998! that actually released though.
seems like every decade intel decides to get into graphics and then abandons it after one lame product
yannigr2 - Friday, October 29, 2021 - linkYes, but today GPU is the king. Intel will go nowhere in servers without a fast GPU.
yannigr2 - Friday, October 29, 2021 - linkNot to mention they will be at the mercy of AMD and Nvidia. Just consider a future where server GPUs from AMD and Nvidia use proprietary interconnect that are specific for EPYC and whatever Nvidia produces based on ARM. Intel will be thrown out of the server market or be relegated as the 3rd option.

This isn't even slightly true. Larrabee never shipped. Intel decided it wasn't competitive, so they switch to making compute-only products and completed TWO generations of Xeon Phi, before cancelling it.
As for their latest dGPU plans, the only thing cancelled is the non-HPC server product, which also never shipped in any quantity. The gaming-oriented Arc products are still slated for release in Q1 2022.
mode_13h - Sunday, October 31, 2021 - linkThe irony is that it's in fact the newly-cancelled Xe-HP that was supposed to take Xeon Phi's place.
