CPU Comparison
Intel Core Ultra 5 235T vs Intel Core Ultra 5 245K
A side-by-side comparison of specs, performance and value. 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 Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
14 cores handle productivity tasks well, but the low PL1 can reduce throughput in sustained multi-threaded workloads compared to non-T models.
14 cores with 159W power headroom handle demanding productivity workloads well, though it sits below Core Ultra 7 and 9 models in heavily threaded tasks.
Gaming
Capable gaming performance with 5.0 GHz boost, though sustained PL1 may limit performance in long gaming sessions without adequate cooling headroom.
The 5.2 GHz boost and strong IPC of Lion Cove deliver excellent gaming performance, particularly at 1080p where CPU limits are most apparent.
Virtualization
Sufficient for a few VMs, but power constraints make it less ideal for heavy virtualization compared to higher-power alternatives.
Good for running multiple VMs with the 14-core configuration and high power budget supporting sustained multi-threaded loads.
Efficiency
Excellent efficiency during sustained workloads due to the low 35W PL1, making it one of the most power-frugal 14-core desktop processors available.
Significantly more efficient than previous-generation K-series processors like the 14600K, thanks to the 3 nm process, though 159W PL2 is still substantial.
