Intel Arc B370 iGPU With 10 Xe3 Cores Is Faster Than RTX 3050 Laptop, 33% Ahead of Arc A380

Intel's Arc B370 iGPU has been tested in Furmark, showcasing a good improvement over the entry-level Arc A380 discrete GPU.

Intel Arc B370 10 Xe3 iGPU Is 33% Faster Than Arc A380 8 Xe dGPU In FurMark Benchmark Leak

The faster Intel Arc B390 iGPU has been making the rounds at various benchmark databases, and while it promises some amazing performance for an integrated chip, today's leak focuses on the Arc B370, which comes with 2 fewer Xe3 cores and slightly lower clock speeds. This iGPU will be featured in certain Panther Lake "Core Ultra Series 3" SKUs.

In terms of specifications, the Intel Arc B370 iGPU is expected to feature 10 Xe3 cores and operate at a peak clock rate of 2300 MHz. The chip is mentioned under the "DEV: 8086-B083 - SUB: 1025-203D - REV: 4" Device ID, and peaked out at 36W. This means that the Panther Lake SKU it was tested on has a power limit of 45W. The specific SKU is the Core Ultra 5 338H.

The performance was measured in the FurMark benchmark using the OpenGL API, and the resolution used was 2560x1440. OpenGL is an older API that previous Arc GPUs had trouble operating within. It wasn't until Intel worked on various optimizations and driver rework to make older APIs workable that these issues were mostly addressed by the time the first Arc Battlemage GPUs hit the shelves.

So, for performance, the Intel Arc B370 iGPU scored 2383 points, which is a decent score considering the RTX 3050 Laptop GPU scores 2186 points, and the Arc A380 scores 1787 points. The Lunar Lake Arc 140V scores 1400 points in the same benchmark. This performance is close to the RTX 3050 Ti Laptop, which has a score of 2485 points.

This means that the Intel Arc B370 iGPU offers a 33% improvement over the discrete Arc A380 graphics card with 8 Xe cores, and a 70% improvement versus the Lunar Lake Arc 140V iGPU. Both of these GPUs have 8 cores, but Lunar Lake comes with the Xe2 architecture, so being 70% faster is quite the jump for a 25% increment in core count.

This isn't even the higher-end 2.4 GHz SKU or the B390 with even more cores, so we can expect a nice update on the iGPU side of things when Panther Lake hits shelves. Expect more information on Panther Lake CPUs and the respective iGPUs at CES 2026.
