Earlier this month Dell sent over a review sample of their new UltraSharp U5223KW monitor. While the model number may not imply much, this monitor is outright incredible. The Dell UltraSharp U5223KW is a 52-inch 6K @ 120Hz monitor with integrated USB hub also working as a KVM switch, 140 Watt power delivery support for USB-C/Thunderbolt laptops, 2.5G Ethernet, and the color reproduction and visuals with this Dell 6K monitor are impeccable.

Those Intel Arc B390 Linux benchmarks so far have been focused on OpenGL and Vulkan graphics, but what about OpenCL and GPU compute with the open-source Intel Compute Runtime? Today's article is looking at the performance of the Xe3 Panther Lake graphics on the newest Compute Runtime release compared to prior Intel graphics generations and the AMD Ryzen AI competition.
