Intel Core 7 253PE vs Intel Core Ultra 7 265F Comparison

Head-to-Head Benchmarks

The benchmark database records a completely one-sided comparison between these two Intel desktop processors. The Intel Core Ultra 7 265F wins all 17 recorded head-to-head tests, with the Intel Core 7 253PE trailing significantly across every workload category. The smallest deficit for the Core 7 253PE appears in single-threaded PassMark tests, where it scores 3955 against the Ultra 7 265F's 4750, a 16.7% gap. Integer math tells a similar story: 114158 versus 138078, a 17.3% difference.

The gap widens considerably in multi-threaded and specialized workloads. In Cinebench R23 multi-core, the Ultra 7 265F posts 41980 while the Core 7 253PE manages 24880, a 40.7% advantage for the Ultra part. The same 40.7% delta appears across every Cinebench generation tested, from R15 multi-core (4231 versus 2507) through R20 multi-core (17631 versus 10449) and R23 single-core (5926 versus 3512). This consistent percentage suggests a fundamental throughput advantage rather than workload-specific optimization.

PassMark tests expose even larger disparities in certain operations. Prime number finding shows the biggest relative gap: the Ultra 7 265F scores 416 versus just 138 for the Core 7 253PE, a 66.8% difference. Floating-point math also heavily favors the Ultra part, with 173855 against 80870, a 53.5% margin. Data encryption follows at 39468 versus 18385, a 53.4% gap. Random string sorting delivers 62439 versus 32777, a 47.5% difference. Extended instructions show a 44.4% gap (39235 versus 21806), while physics simulation trails by 41.8% (3172 versus 1845).

Data compression is the closest of the specialized tests, yet still shows a 33.1% advantage for the Ultra 7 265F with 507018 against 339133. Multithreaded PassMark confirms the pattern: 49410 for the Ultra part versus 29271, a 40.8% gap. The average benchmark score across all tests reinforces the hierarchy: the Ultra 7 265F averages 64438, placing it in the 93rd percentile of all CPUs in the database, while the Core 7 253PE averages 40557, sitting at the 87th percentile.

The nearest rivals for each part provide additional context. The Core 7 253PE sits within 0.3% of the AMD Ryzen 9 7940H (40431 average) and just 0.1% behind the Intel Core Ultra X7 368H (40518). The Ultra 7 265F, by contrast, trades blows with the Intel Core i9-13900KS, which scores 64051 for a 0.6% delta, and the AMD EPYC 7343 at 64202 for a 0.4% delta. The performance tier separation is clear: the Ultra 7 265F competes in a higher class entirely.

Architecture Differences

The two processors represent fundamentally different Intel designs. The Core 7 253PE uses the Bartlett Lake codename and is built on Intel's 10 nm process at Intel's own foundry. It lacks a formal architecture designation in the database. The Ultra 7 265F belongs to the Arrow Lake family, specifically Arrow Lake-S, and uses a 3 nm process fabricated by TSMC. The Ultra part also carries a transistor count of 17,800 million on a 243 mm² die, while the Core 7 253PE has no recorded transistor or die size data.

Core topology differs markedly. The Core 7 253PE provides 10 cores and 20 threads, while the Ultra 7 265F provides 20 cores and 20 threads. This means the Ultra part has twice the physical cores but the same thread count, indicating a different core architecture where each Ultra core does not use simultaneous multithreading. Cache hierarchies also diverge: the Core 7 253PE uses 80 KB L1 per core, 2 MB L2 per core, and 33 MB shared L3. The Ultra 7 265F uses 192 KB L1 per core, 3 MB L2 per core, and 30 MB shared L3. The Ultra part has more cache per core but slightly less total L3.

Memory support separates the two as well. The Core 7 253PE supports both DDR4 and DDR5 memory, while the Ultra 7 265F supports DDR5 only. Both run dual-channel memory buses, but the Ultra part achieves higher memory bandwidth at 102.4 GB/s versus 89.6 GB/s for the Core part. ECC memory is supported on the Core 7 253PE but not on the Ultra 7 265F.

PCIe capabilities also differ. The Core 7 253PE provides Gen 5 with 16 lanes from the CPU, while the Ultra 7 265F provides Gen 5 with 20 lanes. Integrated graphics are present on the Core part as UHD Graphics 730, while the Ultra 7 265F records no integrated graphics. Sockets are incompatible: the Core 7 253PE uses Intel Socket 1700, and the Ultra 7 265F uses Intel Socket 1851.

Specification Differences

The clock speeds favor the Core 7 253PE on paper. It has a 2.50 GHz base clock and 5.50 GHz boost clock, while the Ultra 7 265F operates at 2.40 GHz base and 5.30 GHz boost. Despite the lower clocks, the Ultra part wins every benchmark, indicating architectural efficiency outweighs raw clock rate.

Core and thread counts differ as noted: 10 cores and 20 threads for the Core 7 253PE versus 20 cores and 20 threads for the Ultra 7 265F. Both parts have a 65 watt TDP. The process node differs (10 nm Intel versus 3 nm TSMC), and the foundry differs (Intel versus TSMC). Transistor count and die size are recorded only for the Ultra part: 17,800 million transistors and 243 mm².

Memory support diverges on DDR4 compatibility (Core part only) and ECC (Core part only). Memory bandwidth favors the Ultra part at 102.4 GB/s versus 89.6 GB/s. PCIe lane count favors the Ultra part at 20 lanes versus 16. Integrated graphics exist only on the Core 7 253PE. Release dates differ, with the Ultra 7 265F appearing earlier in the database. The multiplier is locked on both processors. The launch MSRP for the Core 7 253PE is $384, and for the Ultra 7 265F it is $379.

The Verdict

The recorded data leaves no ambiguity. The Intel Core Ultra 7 265F outperforms the Intel Core 7 253PE in every single benchmark in the database, with deltas ranging from 16.7% to 66.8%. The average benchmark score difference is substantial: 64438 versus 40557, a gap of roughly 59%. The percentile ranking confirms the separation, with the Ultra part at the 93rd percentile and the Core part at the 87th percentile.

The Core 7 253PE does offer features the Ultra 7 265F lacks: DDR4 memory support, ECC memory support, and integrated graphics. It also has a higher boost clock at 5.50 GHz versus 5.30 GHz. These attributes make it a viable option for systems requiring legacy memory compatibility or error-correcting memory, or for builds that need an iGPU without a discrete graphics card. The Socket 1700 platform may also be preferable for users with existing motherboards.

The Ultra 7 265F delivers the performance advantage across the board, with double the physical cores, a more advanced 3 nm TSMC process, higher memory bandwidth, and more PCIe lanes. It also launched at a lower MSRP of $379 versus $384 for the Core part. For workloads where raw throughput, encryption, compression, or floating-point math dominate, the data clearly favors the Ultra 7 265F.

Users prioritizing maximum benchmark performance should select the Ultra 7 265F. Users with specific requirements for DDR4, ECC memory, or integrated graphics will find those capabilities only on the Core 7 253PE. The benchmark database shows no recorded scenario where the Core 7 253PE takes the lead.
