Intel Arc Graphics 140T vs Intel Arc 8-Core iGPU

Intel Arc Graphics 140T

Intel Arc 140T is the iGPU used in the Intel Arrow Lake H/HX processor series. It is based on the Xe+ architecture (and not the newer Xe2 architecture that e.g. the Arc Graphics 140V in Lunar Lake uses). The graphics adapter features 8 cores (128 CUs, 8 Raytracing units) with XMX instructions for improved AI performance and 8 MB L2-Cache.

Thanks to the similar core count and clock speed but higher TDP, the performance should be similar to the Xe2 based Intel Arc 140V iGPU. First leaked benchmarks even showed a vastly better performance. All in all, we think that the Arc 140T will be only suited for entry level gaming in lowest settings.

The Arc 140T is integrated in the H and HX series of CPUs but use an own chiplet that is manufactured at TSMC in 5nm (N5P process).

Intel Arc 8-Core iGPU

The Intel Arc iGPU with 8 cores (ID 7D55) is an integrated graphics adapter in Meteor Lake SoCs based on the Xe LPG architecture (similar to the dedicated Arc GPUs, but with a focus on efficiency). It offers all 8 Xe cores (128 Xe vector engines), 8 ray tracing units, 8 samplers and 4 pixel backends.

The Arc name may only be used if at least 16 GB RAM is used in dual channel mode. Otherwise, the only iGPU is called "Intel Graphics" and is also significantly slower.

According to Intel, performance has been doubled compared to the previous generation (probably still in Alder Lake).

The iGPU supports DirectX 12 Ultimate (probably DX 12_2 like the desktop Arc GPUs). The graphics unit also supports XeSS AI Super Sampling.

The media engine of Meteor Lake is in the SOC tile and supports up to 8k60 10-bit HDR encode and decode of MPEG2, AVC, VP9, HEVC and AV1. The display engine is also in the SoC tile and supports HDMI 2.1 and DisplayPort 2.1 20G with up to 8K60 HDR.

The GPU Tile of the Meteor Lake chip is manufactured at TSMC on 5nm (5N process).
