Intel Arc 140V: The First Taste of Xe2 Graphics Architecture
Debuting Next Week
Intel is about to announce and launch its new mobile CPU series, Core Ultra 200V “Lunar Lake.” These low-power mobile chips are designed for lightweight laptops, Mini-PCs, and gaming consoles. This architecture introduces a new NPU (Neural Processing Unit) that is three times faster than its predecessor, Meteor Lake, along with new CPU cores, Lion Cove and Skymont.
For VideoCardz readers, the most important detail is in the integrated graphics subsystem. This is Intel’s first product featuring the new generation of Xe2 graphics. Specifically, this variant is called Xe2-LPG, a low-power version of what will eventually be released as Xe2-HPG for discrete graphics.
The Core Ultra 200V series will offer two configurations of Arc graphics: the Arc 140V with 8 Xe2-Cores and the Arc 130V with 7 Xe2-Cores. The first OpenCL tests with the Arc 140V can be found on CompuBench, a compute-oriented benchmark.
Arc 140V in OpenCL Test
The benchmark does not specify which Core Ultra 7 SKU was used for this test. However, the information tab shows that the GPU has a clock speed of 2000 MHz, leaving only two possibilities: Core Ultra 7 268V (with 32GB RAM) or Core Ultra 7 266V (with 16GB RAM). The GPU is confirmed to have access to 8GB of system shared memory.
It’s important to note that OpenCL benchmarks are not ideal for gaming comparisons. These tests measure raw compute performance, which is more relevant for video processing than for games that do not use this graphics API.
The Arc A370M, with 8 Xe-Cores of Xe-LPG architecture and a TDP ranging from 35 to 50W, is a direct competitor. Despite the Lunar Lake’s lower TDP of 17-30W, it outperforms the A370M significantly. The 140V also surpasses the Radeon 780M and is close to the GTX 1650 in performance. However, again, keep in mind that this is not a gaming benchmark.

Launch Details
The Intel Core Ultra 200V is set to launch on September 3rd. Intel has already released a driver supporting these graphics, so once a content creator with access to retail channels gets a sample, we should start seeing gaming performance reviews. If the performance in games matches that of the Radeon 780M, it would be a positive outcome and could provide Intel with an opportunity to expand in the handheld gaming market.
