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 Core Ultra 5 245T is the only T-series Arrow Lake processor with the full 64EU Arc Xe-LPG iGPU and ECC memory support, running 14 cores (6P+8E) with a 35W PL1 and 114W PL2 in a compact, power-efficient package priced at $270.
Specifications

Architecture Overview
The 245T uses the same Arrow Lake-S tile architecture as the 245K but operates under T-series power constraints. It retains the full 64EU graphics tile and ECC-capable memory controller, making it architecturally equivalent to the K-series minus the unlocked multiplier and with different power limits.
CPU Design
6 Lion Cove P-cores and 8 Skymont E-cores with a low 2.2 GHz base clock but 5.1 GHz maximum boost. The E-cores reach 4.5 GHz, the highest E-core boost in the Ultra 5 family.
Memory Subsystem
Dual-channel DDR5-6400 with ECC support, a feature shared only with the 245K in the Ultra 5 lineup.
PCIe & I/O
20 Gen 5 lanes plus 4 Gen 4 lanes, identical to other full-configuration Arrow Lake-S processors.
Overclocking
Multiplier is locked. The T-series power limits (35W PL1, 114W PL2) can typically be adjusted in motherboard BIOS on compatible boards.
- New Lion Cove and Skymont core architectures
- 64EU iGPU vs 24EU on previous T-series
- Built-in NPU 3 for AI workloads
- ECC memory support (absent on previous T-series)
- PCIe 5.0 from CPU (vs 4.0 on 14600T)
- 3 nm manufacturing process (vs Intel 7 on 14600T)
- Higher E-core boost clocks at 4.5 GHz
Key Highlights

- At $270, only $49 less than the fully unlocked 245K
- Power limit adjustments may be restricted by some motherboard BIOS implementations
History
The Core Ultra 5 245T emerged from Intel's recognition that the traditional T-series formula of stripping features along with power budget was leaving a gap in the market.
Previous T-series processors like the i5-14600T not only had lower power limits but also reduced iGPU size and lacked premium features. The 245T broke this pattern by retaining the full 64EU graphics tile and ECC memory controller from the K-series while applying T-series power constraints.
This approach was likely driven by the growing demand for compact workstations in professional environments, where users needed reliable ECC memory, decent integrated graphics for multi-monitor setups, and low power consumption for small enclosures.
The decision to price it at $270, just $1 above the non-T 235A, made the feature comparison particularly stark and arguably undercut the 235A's value proposition for buyers who didn't specifically need the higher sustained PL1.
Improvements over Previous Generation
- New Lion Cove and Skymont core architectures
- 64EU iGPU vs 24EU on previous T-series
- Built-in NPU 3 for AI workloads
- ECC memory support (absent on previous T-series)
- PCIe 5.0 from CPU (vs 4.0 on 14600T)
- 3 nm manufacturing process (vs Intel 7 on 14600T)
- Higher E-core boost clocks at 4.5 GHz
Alternatives & Competitors
Should You Buy It?
Recommended for the right buyer
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.
Avoid if…
- You are building a standard ATX system where power is not constrained (consider 245K or 235A instead)
- You never use integrated graphics and don't need ECC (the 225F or 235T save money)
- You need sustained multi-threaded performance (the 35W PL1 will limit throughput)
Use Cases
Interesting Facts
The 245T is the only T-series Arrow Lake processor with the 64EU iGPU and ECC support, making it architecturally a K-series chip with T-series power limits.
Its E-cores boost to 4.5 GHz, which is higher than the E-core boost on both the 235T (4.4 GHz) and 245K (4.6 GHz is higher, but the 245T's 4.5 GHz is notable for a T-series).
The 64EU iGPU at 1900 MHz dynamic frequency is the same graphics configuration as the 245K, just running in a lower power envelope.
At $270, the 245T costs only $1 more than the 235A but offers a larger iGPU, ECC support, and higher boost clocks.
The combination of ECC memory and integrated graphics in a T-series power profile is unprecedented in Intel's desktop lineup.
Its 29 TOPS total AI performance comes from 8 CPU + 8 GPU + 13 NPU, showing the 64EU GPU's larger AI contribution.
The 245T's 114W PL2 is the same as the 235T's, despite the larger iGPU, suggesting the graphics tile is power-gated during CPU-heavy bursts.
Intel included vPro support on the 245T, making it suitable for managed enterprise thin-client and compact workstation deployments.
The A0 stepping indicates the 245T used early production silicon, while the 245K launched on the more refined B0 stepping.
The 35W PL1 means the 245T can be passively cooled in some scenarios, though the 114W PL2 makes active cooling prudent.
