Where Each One Wins

The Intel Core Ultra 5 245 dominates the benchmark comparison, winning 16 of 17 head-to-head tests. Its wins span every Cinebench generation (R15, R20, R23) in both multi-core and single-core tests, and most PassMark workloads. The Core Ultra 5 245 delivers substantially higher scores in data compression (400942 vs 339133), data encryption (30236 vs 18385), floating-point math (120548 vs 80870), and physics (2569 vs 1845). This makes it the clear choice for rendering, encryption workloads, scientific computing, and general productivity.

The Intel Core 7 253PE wins exactly one benchmark: PassMark integer math, scoring 114158 against 91187, a 25.2% advantage. This single victory indicates a specific strength in integer-heavy workloads, which can matter for certain database operations, financial calculations, or legacy software that relies heavily on integer arithmetic. Beyond that one test, the Core 7 253PE trails across the board, with deficits ranging from 10% in PassMark single-thread to 62.2% in PassMark find prime numbers.

The benchmark data indicates that for users running mixed workloads, the Core Ultra 5 245 is overwhelmingly the stronger processor. The Core 7 253PE only makes sense for workloads that are almost exclusively integer-math bound, where its 25.2% advantage could translate into tangible performance gains.

Architecture Differences

The two processors come from fundamentally different architectural generations. The Intel Core 7 253PE is based on Bartlett Lake, built on Intel's 10 nm process. The Intel Core Ultra 5 245 uses Arrow Lake-S architecture, built on TSMC's 3 nm process. This process node difference, 10 nm versus 3 nm, contributes significantly to the performance gap observed in the benchmarks.

The Core 7 253PE uses a traditional core layout with 10 cores and 20 threads, relying on simultaneous multithreading (SMT) to process two threads per core. The Core Ultra 5 245 has 14 cores and 14 threads, meaning it does not use SMT; each core handles exactly one thread. Despite having fewer threads overall (14 vs 20), the Core Ultra 5 245 still outperforms the Core 7 253PE in all multi-threaded benchmarks, which indicates that its individual cores are substantially more efficient.

Cache hierarchies differ notably. The Core 7 253PE has 80 KB L1 cache per core, 2 MB L2 cache per core, and 33 MB shared L3 cache. The Core Ultra 5 245 has 192 KB L1 per core, 3 MB L2 per core, and 24 MB shared L3 cache. The Core Ultra 5 245 has larger per-core caches but a smaller shared L3 pool. The total cache per core is significantly higher on the Core Ultra 5 245, which helps explain its superior single-core performance.

The integrated graphics also reflect architectural differences. The Core 7 253PE uses UHD Graphics 730, while the Core Ultra 5 245 uses Arc Xe-LPG Graphics 64EU. The Arc-based solution in the Core Ultra 5 245 represents a newer generation of Intel integrated graphics.

Memory architecture differs as well. The Core 7 253PE supports both DDR4 and DDR5, giving it flexibility for older platforms. The Core Ultra 5 245 supports only DDR5 but has higher memory bandwidth: 102.4 GB/s versus 89.6 GB/s for the Core 7 253PE.

Specification Differences

The two processors differ in several key specifications. The Core 7 253PE has 10 cores and 20 threads, while the Core Ultra 5 245 has 14 cores and 14 threads. Base clocks differ: 2.50 GHz for the Core 7 253PE versus 3.50 GHz for the Core Ultra 5 245. Boost clocks also differ: 5.50 GHz for the Core 7 253PE versus 5.10 GHz for the Core Ultra 5 245. The Core 7 253PE has a higher boost clock, but the Core Ultra 5 245 has a higher base clock.

Process node and foundry differ: the Core 7 253PE uses 10 nm at Intel, while the Core Ultra 5 245 uses 3 nm at TSMC. The Core Ultra 5 245 has a documented transistor count of 17,800 million and a die size of 243 mm²; these figures are not listed for the Core 7 253PE.

Head-to-Head Benchmarks

The most striking pattern in the head-to-head data is the consistency of the Core Ultra 5 245's victories. Across all six Cinebench tests (R15, R20, R23, each in multi-core and single-core), the Core Ultra 5 245 wins by exactly 24.4% in each case. The specific scores are: Cinebench R15 multi-core 3318 vs 2507, R15 single-core 468 vs 354, R20 multi-core 13828 vs 10449, R20 single-core 1952 vs 1475, R23 multi-core 32924 vs 24880, and R23 single-core 4648 vs 3512. This uniform 24.4% delta across all Cinebench variants suggests a consistent architectural efficiency advantage rather than a workload-specific strength.

In PassMark tests, the Core Ultra 5 245's margins vary more widely. The largest deficit for the Core 7 253PE appears in PassMark find prime numbers, where the Core Ultra 5 245 scores 365 against just 138, a 62.2% advantage. This indicates a major difference in integer-heavy algorithmic workloads. Data encryption shows a 39.2% gap (30236 vs 18385), extended instructions shows 34.5% (33304 vs 21806), and random string sorting shows 33.3% (49140 vs 32777). Floating-point math favors the Core Ultra 5 245 by 32.9% (120548 vs 80870).

The Core 7 253PE's single win comes in PassMark integer math, where it scores 114158 versus 91187 for the Core Ultra 5 245, a 25.2% advantage. This is the only test where the Core 7 253PE leads, and the margin is substantial. However, it is an isolated result; the Core Ultra 5 245 wins PassMark multi-thread by 24.4% (38706 vs 29271), PassMark physics by 28.2% (2569 vs 1845), and PassMark single-thread by 10% (4394 vs 3955, reported identically as passmark_single_thread and passmark_singlethread).

The overall average benchmark scores confirm the hierarchy. The Core Ultra 5 245 has an average benchmark score of 48995, placing it in the 90th percentile of all CPUs. The Core 7 253PE has an average benchmark score of 40557, placing it in the 87th percentile. The 20.8% difference in average scores aligns with the consistent 24.4% Cinebench deltas.

The Verdict

The benchmark data clearly favors the Intel Core Ultra 5 245 for nearly every workload. It wins 16 of 17 head-to-head tests, with margins ranging from 10% in single-threaded PassMark to 62.2% in prime number calculations. Its 14 cores on a 3 nm TSMC process deliver superior efficiency compared to the 10-core, 20-thread Bartlett Lake design of the Core 7 253PE. The Core Ultra 5 245 also offers higher memory bandwidth (102.4 GB/s vs 89.6 GB/s), more PCIe lanes (20 vs 16), and a more modern Arc integrated GPU.

The Core 7 253PE is the correct choice only for workloads that are almost exclusively integer-math bound. Its 25.2% advantage in PassMark integer math is the sole bright spot in the benchmark results. For users running database queries, financial simulations, or legacy applications that depend heavily on integer arithmetic, this advantage could be meaningful. The Core 7 253PE also offers DDR4 memory support, which may matter for users upgrading an existing DDR4 platform on Socket 1700.

For all other use cases, including rendering, video encoding, data compression, encryption, scientific computing, and general productivity, the Core Ultra 5 245 is the stronger processor. Its uniform 24.4% lead across all Cinebench tests demonstrates a consistent architectural superiority. The Core Ultra 5 245 also sits in the 90th percentile of all CPUs, compared to the 87th percentile for the Core 7 253PE, and its nearest rivals include the AMD Ryzen 9 7900 and Intel Core i5-14600K, both of which it slightly trails or leads by less than 1%.

The data suggests that the Core Ultra 5 245 is the more capable processor for most buyers, despite having fewer threads. The architectural advancements in Arrow Lake, combined with the smaller 3 nm process node, deliver performance that the older Bartlett Lake design cannot match. The Core 7 253PE remains a viable option only for the narrow integer-math niche and for users who need DDR4 compatibility on Socket 1700.
