CPU Comparison
Intel Core Ultra 5 245T vs Intel Core Ultra 5 250K Plus
A side-by-side comparison of specs, performance and value. The Intel Core Ultra 5 245T is a distinctive variant in the Arrow Lake-S lineup that combines the larger 64 EU Arc Xe-LPG integrated graphics and ECC memory support typically associated with K-series processors with the T-series low-power profile. Launched on January 7, 2025, at $270, it features the same 14-core configuration (6 Lion Cove P-cores and 8 Skymont E-cores) as other full Ultra 5 models but operates with a 35W PL1 sustained power limit and 114W PL2 turbo limit. This makes it the only T-series Arrow Lake processor with the enhanced 64EU iGPU and ECC capability, positioning it uniquely for compact workstations, small form factor systems with graphics needs, and embedded applications where integrated graphics quality and data integrity matter but power budget is constrained. The 5.1 GHz maximum boost is higher than the 235T's 5.0 GHz, and total AI performance reaches 29 TOPS. Built on the A0 stepping, the 245T fills a very specific but important niche that no other processor in the Arrow Lake-S stack addresses.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Good productivity performance with 14 cores, though the 35W PL1 limits sustained multi-threaded throughput compared to non-T models.
18 cores deliver strong multi-threaded performance. The iGPU can accelerate video encoding in supported applications, providing a small productivity edge over the KF variant.
Gaming
The 5.1 GHz boost and 14 cores provide strong gaming performance when paired with a discrete GPU. The 64EU iGPU can handle light gaming at 720p/1080p low, a significant step up from the 235T's 24EU.
With a discrete GPU, gaming performance is identical to the 250KF Plus — excellent at 1080p and 1440p. The iGPU can handle eSports titles at 720p/1080p low for troubleshooting or casual play.
Virtualization
Adequate for several VMs, with ECC memory adding reliability for data-sensitive virtualization workloads.
Efficiency
Excellent efficiency during sustained operation at 35W PL1, with the 3 nm process ensuring strong performance per watt.
Standard 125W/159W power profile for Arrow Lake desktop. The 3nm compute tile helps at idle and light loads, but full-load power is substantial.

Our Verdict on Each
A uniquely positioned processor that combines premium features (64EU iGPU, ECC support) with T-series power efficiency, ideal for SFF builds that need strong integrated graphics and data integrity.
Best for: Small form factor or power-constrained builds that need the 64EU iGPU for light graphics work, multi-display support, or ECC memory for data integrity, but cannot accommodate K-series power levels.
Read the full reviewThe 250K Plus might be the best all-around value in Intel's entire desktop lineup. For just $15 over the KF variant, you get a fully functional iGPU, 18 cores, an unlocked multiplier, and DDR5-7200 support. It eliminates every excuse not to build on Arrow Lake.
Best for: Building a new desktop where you want the safety net of integrated graphics, maximum cores per dollar, and the option to overclock — all without breaking the bank.
