Intel Core Ultra 5 225T vs Intel Core Ultra 7 265F Comparison

The Intel Core Ultra 5 225T and Intel Core Ultra 7 265F are both desktop processors from Intel’s Core Ultra Series 2, built on the Arrow Lake architecture and fabricated on a 3 nm process at TSMC. While they share the same socket, memory support, and transistor count, the data reveals a fundamental performance gap: the Core Ultra 7 265F wins every single recorded benchmark in the head-to-head comparison, with a perfect 17-win record against zero wins for the Core Ultra 5 225T. The average benchmark score for the Ultra 7 265F is 64,438, placing it in the 93rd percentile of all CPUs, while the Ultra 5 225T averages 30,468 and sits in the 82nd percentile. The following analysis breaks down where each processor excels, the architectural reasons for the divide, and the specific numerical margins across all tested workloads.

Where Each One Wins

The Core Ultra 7 265F claims victory in every category of the recorded benchmarks, making the use-case split straightforward: the Ultra 7 is the dominant choice for all measured workloads, while the Ultra 5 225T holds no benchmark wins. In multi-threaded rendering tasks, the Ultra 7 265F delivers 4,231 points in Cinebench R15 multicore, compared to 2,214 for the Ultra 5 225T, a 91% advantage. The gap widens in Cinebench R23 multicore, where the Ultra 7 scores 41,980 versus 21,971, again a 91% improvement. These results indicate that the Ultra 7 265F is substantially better suited for CPU-intensive content creation, 3D rendering, and video encoding, where multiple cores are fully utilized.

Single-threaded performance also favors the Ultra 7 265F, though by a smaller margin. In Cinebench R23 single-core, the Ultra 7 scores 5,926 against 3,101 for the Ultra 5, a 91% lead. The PassMark single-thread test shows a narrower difference: 4,750 versus 4,348, an 8.5% advantage for the Ultra 7. This suggests that for lightly threaded applications such as everyday productivity, web browsing, and legacy software, the Ultra 5 225T remains competitive, but the Ultra 7 still holds the edge. In integer math, a proxy for general-purpose computing, the Ultra 7 scores 138,078 versus 59,543, a 132% difference, while floating-point math shows 173,855 versus 82,751, a 110% gap. The Ultra 5 225T is not without merit in lower-power scenarios, but the recorded data provides no workload where it outperforms the Ultra 7 265F.

Architecture Differences

Both processors use the same Arrow Lake-S die, fabricated by TSMC on a 3 nm process, with identical transistor counts of 17,800 million and a die size of 243 mm². The foundational architecture is the same, but the core configurations diverge significantly. The Core Ultra 5 225T has 10 cores and 10 threads, while the Core Ultra 7 265F doubles the thread count with 20 cores and 20 threads. This additional parallelism is the primary driver of the multi-threaded performance gap. The Ultra 7 also has a higher boost clock of 5.30 GHz compared to 4.90 GHz on the Ultra 5, while the base clocks are similar at 2.40 GHz and 2.50 GHz respectively.

Cache hierarchy differs in the shared L3 cache: the Ultra 7 265F has 30 MB of shared L3, while the Ultra 5 225T has 20 MB. Both processors feature 192 KB of L1 cache per core and 3 MB of L2 cache per core, with no 3D V-Cache present. The integrated graphics also separate the two: the Ultra 5 225T includes Arc Xe-LPG Graphics with 16 execution units, while the Ultra 7 265F has no integrated graphics (N/A). This means the Ultra 5 can output video without a discrete GPU, whereas the Ultra 7 requires a separate graphics card. Both support DDR5 memory in a dual-channel configuration with a memory bandwidth of 102.4 GB/s, and neither supports ECC memory. The PCIe interface is identical: Gen 5 with 20 lanes from the CPU. The Ultra 7 265F was released on January 7, 2025, while the Ultra 5 225T debuted on January 1, 2025, both are active in production, and neither has an unlocked multiplier.
