Intel has officially unveiled its first two Arc Alchemist A-Series GPUs, the ACM-G10 with up to 32 and the ACM-G11 with up to 8 Xe Cores.

Intel's First Discrete Gaming GPUs Unveiled: Arc A-Series In ACM-G10 32 Xe & ACM-G11 8 Xe Flavors

The Intel ARC Alchemist GPUs are designed primarily for desktop and notebook platforms. From the information that we have currently gathered, the lineup will consist of two GPUs and each of those will have various SKUs, and each of those SKUs will be featured in a range of solutions for desktop graphics cards and mobility GPUs.

All Intel ARC Alchemist GPUs will utilize the TSMC 6nm process node and from what we already know, the Intel Xe-HPG Alchemist GPU features a Xe-Core which is the fundamental DNA of the 1st Gen ARC lineup. The Xe-Core is a compute block that is composed of 16 Vector Engines (256-bit per engine) and 16 Matrix Engines (1024-bit per engine).

Each Vector Engine is composed of 8 ALUs so, in total, we are looking at 128 ALUs per Xe-Core. The Xe-Core further features its own dedicated 192 KB L1 cache so that is a total of 6 MB of L1 cache on the complete chip.

Intel fuses four Xe-Cores together to form a Render Slice which is composed of 4 Ray Tracing Units, four Sampler Units, Geometry/Rasterize/HiZ engines, and two Pixel Backend blocks with 8 units on each. These Render Slices are put together to form the main GPUs. The flagship is composed of an 8 Render Slice configuration which features 32 Xe-Cores, 512 Vector Engines, and 4096 ALUs. There will be different configurations with 2, 4, 6 Render Slices but we are focusing on the flagship part in this report.

Intel’s Xe HPG architecture will be able to achieve 1.5x higher clock rates than Xe LP and also deliver 1.5x higher performance per watt. This means we are looking at clocks in the 2.1 GHz range considering the Xe LP discrete GPUs were clocked at 1.4 GHz. It also means that Intel will be able to squeeze additional power out of the architecture, should they want to, without increasing the power draw (or reducing the power draw while keeping performance constant.

Out of the two GPUs, the first one will be known as ACM-G10. This is the top SKU and will be featured in mainstream and high-end designs. The second GPU is known as ACM-G11. This is an entry-level SKU and as such, will be featured in entry-level and mainstream designs. Each GPU has its own SKUs with different specifications.

Each Matrix Engine block is also referred to as an XMX block which will handle tensor operations in both FP16 (128 FP16 ops/clock), INT8 (256 INT8 ops/clock), & INT4 (512 INT4/INT2 ops/clocks) mode. The XMX engines allow for up to 16 times the compute capabilities for INT8 inferencing. This helps boost the performance through the dedicated XeSS (Xe Super Sampling) technology.

Coming to the media engine, the Intel Arc Alchemist discrete GPUs are equipped with the latest tech which includes up to 8K60 12-bit HDR decode, up to 8k 10-bit HDR encode, VP9, AVC, HEVC, and AV1. Intel is partnering with top brands to leverage the AV1 capabilities of their Arc GPUs through the Alliance for Open Media. The new AV1 engine will provide 50x faster GPU encoding capabilities versus software mode. The tech will be integrated into several creation tools such as FFMPEG, Handbrake, Adobe Premiere Pro, DaVinci Resolve, and XSplit on launch.

In addition to that, the Intel Arc Xe Display Engine will support the latest display standards such as HDMI 2.0b, DisplayPort 1.4a, and 2.0 10G. Support for a variety of high resolution and high refresh rate modes is also going to be available which include:

2x 8k60 HDR4x 4k120 HDR1080p3601440p360

As for adaptive syncing technology, Intel's discrete Arc Alchemist GPUs will support both Adaptive-Sync and Speed Sync technology. The former will sync the display's refresh rate to provide a smooth and tear-free experience while the latter will speed up the latest frame, delivering low latency, no tearing, and no cap. There's also a third mode known as Smooth Sync which will blur distracting screen tears with a dithering filter.
