Strengths

16GB at a notably low price for the capacity
Growing support via IPEX-LLM, Vulkan, and SYCL back-ends
A reasonable 225W draw

Weaknesses

No CUDA, so software support is less mature and more fiddly than NVIDIA
560 GB/s bandwidth and driver gaps mean lower real-world throughput
Fewer optimised kernels, so many tools run slower or need workarounds
