Intel's Raja Koduri Teases Pictures of Xe-HP GPUs

Intel's Chief Architect Raja Koduri tweeted the first images of the company's new Xe HP GPUs that that are currently sampling to Intel's customers. The cards, built on the 10nm SuperFin process, are also being used as the software development vehicle for the Aurora Supercomputer. The exascale-class supercomputer has been delayed due to Intel's struggles with the 7nm node used in its Ponte Vecchio GPUs, but due to similarities between the cards, the new Xe-HP cards can be used to develop software for Aurora. The image above shows the already-announced XG310 Intel data center GPU flanked by the new Xe-Hp models. 

The variant on the left is clearly a traditional PCIe 3.0 x16 add-in card (AIC) with a full-height, 3/4 length form factor, just like the XG310 model next to it. As a quick reminder, the Intel-powered XG310 GPU consists of four separate Iris Xe Max discrete graphics chips, formerly codenamed DG1, that are also used as discrete GPUs in laptops. Instead of the typical use case for server GPUs, like machine learning workloads, the four processors work in tandem to process cloud gaming and media transcode and encode workloads for real-time video streaming.

Given the similarities between the two cards, we can expect the Xe HP GPUs to employ a similar architecture based on multiple Xe graphics die, but paired with HBM memory tied to the GPUs via Intel's EMIB packaging technology. Intel is expected to offer different models with either 1, 2, or 4 tiles (GPU die) to satisfy various workload requirements.

The Xe-HP cards' execution units (EU) also support different data formats tailored for data center and HPC usage, like bfloat16 for AI workloads, DP4A convolution instructions for deep learning and Intel's AMX instructions. 

Given the slim size of the two Xe HP variants, it's clear the passively-cooled single-slot designs have a relatively tame TDP limit. On the right, we can see a single auxiliary 8-pin power connector for the card. A single 8-pin can deliver up to 225W safely, and the PCIe slot can deliver 75W; we're looking at a possible 300W maximum power draw for the card. 

Intel didn't share further details of the cards pictured, but we expect more details to filter out as they ship to customers.

    Last time I checked it was 150 watts for 8 pins PCIe connector?

    also looking at the card , single slot , and passive cooled , how can this card cool 150+75 watts power used ? something is not right here

    These are server GPUs, they use the fans in the rack units for cooling. ITs not passive.

    Anything without a fan on top is called passive .. PC airflow does not mean it is not passive .

    Besides , look at the Pic , they are one slot thin cards , Air flow there needs a blower fan on top .. air wont be pushed inside from Server fans enough.

    Correct this please . the 225 is the Total 150 (8 pins power) +75 (motherboard) = 225W

    and there is no possible 300 watts here

    It's too bad Intel's consumer GPUs aren't ready yet. This would be the perfect time to collect market share given the supply problems Nvidia and AMD have been having. I still wouldn't trust Intel to not kill support for their GPU products in a few years, but there's no denying that people are doing/paying crazy things for GPUs right now.

    You underestimate what server fans are capable of. There's a reason why people at the office quip about jets taxiing for takeoff when someone powers on a server that had been off. Likewise, people compare the backs of some of the servers to hair dryers. Most components are designed to take advantage of the array of powerful fans near the front. I'm not sure that much airflow and noise qualifies as generic case airflow -- seems more like active cooling with detached fans.

    14 nm GPUs are back again yay !
    RX580 returns in 2021.
    namecode for the process : Nostalgia

    the "enthousiast" card would have 2-4 of those lol


    that or it's yet another competitor for TSMC's 7nm wafers

    as for the drivers, i would not be too worried. they make GPUs too since a long time, inside their CPUs. Their drivers support is pretty good.

    The 150W rating is an artificial limit most likely for "covering all bases" safety reasons. If you build the connectors to the appropriate specifications as defined by Molex (who designed it) and use the appropriately sized wires, you can get well over 150W on an 8-pin PCIe power cable.

    The writer mistake is clear , he said 225 watts for 8 pins which is actually 150 (8 pins) + 75 (mobo) ... then he added another 75 watts above it. this is not a coincidence.
