Desktop
The Intel Core Ultra 5 235T is a 14-core Arrow Lake-S processor designed for users who prioritize low power consumption without sacrificing core count. Built on TSMC's 3 nm process, it features 6 Lion Cove P-cores and 8 Skymont E-cores, delivering a hybrid architecture that balances single-threaded responsiveness with multi-threaded throughput. What sets the 235T apart is its T-series power profile: while the labeled TDP sits at 65 W, the PL1 sustained power limit is just 35 W, making it exceptionally well-suited for small form factor builds, mini-ITX systems, and thermally constrained environments. Despite the low sustained power, the PL2 turbo limit of 114 W allows the processor to burst up to 5.0 GHz when headroom is available. It includes a 24 EU Arc Xe-LPG integrated GPU for basic display duties and light workloads, along with an NPU 3 rated at 13 TOPS for local AI inference tasks. Launched on January 7, 2025, at $247, the 235T occupies a specific niche for builders who want modern Arrow Lake features in a power-efficient package.
The Core Ultra 5 235T combines 6 P-cores and 8 E-cores on a 3 nm process with a remarkably low 35W PL1, enabling compact builds that still benefit from Intel's latest hybrid architecture, NPU 3 AI acceleration, and Arc Xe-LPG integrated graphics.
Specifications
Performance
14 cores handle productivity tasks well, but the low PL1 can reduce throughput in sustained multi-threaded workloads compared to non-T models.
Sufficient for a few VMs, but power constraints make it less ideal for heavy virtualization compared to higher-power alternatives.
Capable gaming performance with 5.0 GHz boost, though sustained PL1 may limit performance in long gaming sessions without adequate cooling headroom.
Excellent efficiency during sustained workloads due to the low 35W PL1, making it one of the most power-frugal 14-core desktop processors available.
- •5.0 GHz maximum boost provides strong single-threaded performance
- •114W PL2 burst allows good frame rates in short sessions
- •24EU iGPU is only suitable for very light gaming or older titles
- •A discrete GPU is recommended for any serious gaming
- •NPU 3 delivers 13 TOPS for sustained AI tasks
- •Total of 27 TOPS when combining CPU, GPU, and NPU
- •Suitable for background blur, noise cancellation, and local LLM inference

Architecture Overview
The Core Ultra 5 235T uses Intel's Arrow Lake-S tile-based architecture manufactured primarily by TSMC on their 3 nm process for the compute tile. The processor separates the P-cores, E-cores, GPU, and I/O into distinct dies connected via Foveros interconnect, allowing each tile to use the optimal manufacturing process.
CPU Design
6 Lion Cove P-cores handle foreground and latency-sensitive tasks with wide out-of-order execution, while 8 Skymont E-cores provide throughput-oriented parallel processing. Arrow Lake removes Hyper-Threading, relying instead on the physical E-core count for multi-threaded performance.
Memory Subsystem
Dual-channel DDR5 with native support for 6400 MT/s, providing up to 102.4 GB/s bandwidth. ECC memory is not supported on this SKU.
PCIe & I/O
20 PCIe 5.0 lanes from the CPU for graphics and NVMe storage, plus 4 PCIe 4.0 lanes for additional connectivity.
Overclocking
The multiplier is locked, limiting overclocking to BCLK adjustments and memory tuning.
- New Lion Cove P-core architecture with significant IPC gains
- Skymont E-cores with dramatically improved performance over Gracemont
- Built-in NPU 3 for AI workloads
- DDR5 native support at higher speeds
- PCIe 5.0 support from the CPU
- Transition to tile-based Foveros packaging
Key Highlights
- Extremely low 35W PL1 for SFF compatibility
- 14 cores provide strong multi-threaded capability
- NPU 3 enables local AI workloads
- 3 nm process delivers excellent efficiency
- Integrated graphics eliminate the need for a basic discrete GPU
- 114W PL2 allows strong burst performance
- Low 2.2 GHz base clock affects sustained performance
- Locked multiplier prevents CPU overclocking
- Small 24EU iGPU limits graphics capability
- No ECC memory support
- A0 stepping may have early-silicon quirks
- PL1 of 35W can throttle in poorly ventilated SFF cases during sustained loads
History
The Core Ultra 5 235T represents Intel's recognition that the small form factor PC market needed Arrow Lake's architectural improvements without the power budget of K-series or standard models.
Traditional T-series processors were often afterthoughts, but the 235T arrived as part of a deliberate launch wave in January 2025, alongside the 245T and 225F, filling out the Arrow Lake-S lineup for specific use cases.
The decision to include an NPU and Arc iGPU even in a low-power T-series SKU signals Intel's commitment to making AI and integrated graphics baseline features rather than premium add-ons.
By setting PL1 at just 35W while retaining a 14-core configuration, Intel created a processor that can idle near tablet-level power consumption while still bursting to competitive performance when needed, a duality that SFF builders had long been requesting.
