Last month Intel announced the Arc Pro B70 with 32GB of GDDR6 video memory for this long-awaited Battlemage G31 graphics card. This new top-end Battlemage graphics card with 32 Xe cores and 32GB of GDDR6 video memory offers a lot of potential for LLM/AI and other use cases, especially when running multiple Arc Pro B70s. Last week Intel sent over four Arc Pro B70 graphics cards for Linux testing at Phoronix. Given the current re-testing for the imminent Ubuntu 26.04 release, I am still going through all of the benchmarks especially for the multi-GPU scenarios. In this article are some initial Arc Pro B70 single card benchmarks on Linux compared to other Intel Arc Graphics hardware across AI / LLM with OpenVINO and Llama.cpp, OpenCL compute benchmarks, and also some OpenGL and Vulkan benchmarks. More benchmarks and the competitive compares will come as that fresh testing wraps up, but so far the Arc Pro B70 is working out rather well atop the fully open-source Linux graphics driver stack.
The Arc Pro B70 features 32 Xe cores, 8 render slices, 32 ray-tracing units, 256 XMX engines, a 2.8GHz graphics maximum dynamic clock, and 2.28GHz graphics clock.
The Intel Arc Pro B70 is rated for a 230 Watt total board power and requires one eight pin PCIe power connection.
In today’s article are some initial benchmark of the Arc Pro B70 up against other Arc Pro and Arc consumer hardware on Linux. All of the tests freshly conducted on a clean Ubuntu 26.04 daily install in its near final state with the Linux 7.0 kernel and Mesa 26.0 graphics drivers. Plus having installed the latest Intel Compute Runtime 26.09.37435.1 with IGC 2.30.1 compiler for the GPU compute benchmarks. The Intel graphics cards tested off this fresh driver stack included:
– Arc Pro B50
– Arc Pro B70
– Arc B580
– Arc A770
That was limited by the cards I had available with having not received any review hardware, for example, of the Arc Pro B60. Testing of the AMD Radeon PRO and NVIDIA RTX hardware that I have available is currently being done atop the brand new Ubuntu 26.04 stack and I will have up those competitive comparisons in the next week or two. Similarly the multi-card Arc Pro B70 graphics cards are also being worked on as well as setting up more AI/LLM benchmarks like vLLM on Intel. Today is just what was available with having only unexpectedly received the cards last week.
All these graphics cards were tested on Ubuntu 26.04 with a Ryzen Threadripper 9980X workstation. Unfortunately no graphics card power consumption numbers are in this article due to the power usage not being exposed by the Intel Xe driver on Linux 7.0 via its conventional sysfs interface.
Thanks to Intel for supplying the graphics cards for Linux testing at Phoronix.
