Intel Core 7 253PTE vs Intel Core Ultra 5 245K Comparison

Where Each One Wins

The benchmark data splits these two processors into distinct use-case profiles. The Intel Core Ultra 5 245K dominates the overall benchmark tally with 15 wins out of 17 head-to-head comparisons, while the Intel Core 7 253PTE takes only 2 wins. That lopsided count, however, obscures a meaningful specialization in the Core 7 253PTE's favor.

The Core 7 253PTE wins in Cinebench R23 single-core with a score of 3003 against 2132 for the Core Ultra 5 245K, a 40.9% advantage. It also wins PassMark integer math at 119552 versus 98524, a 21.3% lead. These two results point toward workloads that depend on high-frequency single-thread execution and integer-heavy calculation, such as legacy application compatibility, certain database workloads, or lightly threaded productivity tasks where clock speed matters more than core count.

The Core Ultra 5 245K, by contrast, sweeps nearly everything else. Its advantages are particularly pronounced in multi-threaded rendering, encryption, compression, and physics simulation. The Cinebench R15 multi-core score of 3850 versus 2144 represents a 44.3% lead, and the R20 multi-core result of 15368 versus 8935 is a 41.9% margin. PassMark multi-thread shows 43047 against 25031, again a 41.9% gap. These results confirm the Core Ultra 5 245K as the stronger choice for parallel compute, content creation, and data processing tasks.

The percentile rankings align with this split. The Core 7 253PTE sits at the 84th percentile of all CPUs in the database, while the Core Ultra 5 245K reaches the 91st percentile. The average benchmark scores differ substantially: 34962 for the Core 7 253PTE versus 54053 for the Core Ultra 5 245K. The nearest rivals for each processor reinforce their respective positions. The Core 7 253PTE trades nearly evenly with the Intel Core i7-13800H at a 0.1% deficit, the Intel Core i9-12900HX also at 0.1% behind, and the Intel Xeon 6349P at 0.2% ahead. The Core Ultra 5 245K sits close to the Intel Xeon 6505P, 0.7% ahead, and the Intel Core i7-14700F, 0.8% ahead, while trailing the AMD Ryzen 9 9900X3D by 1.3%.

For a desktop system that must handle mixed workloads, the Core Ultra 5 245K is the more balanced performer. For a system where single-thread responsiveness and integer throughput take priority, the Core 7 253PTE has a narrower but real edge.

Head-to-Head Benchmarks

The Cinebench suite reveals a complex picture. In multi-core tests, the Core Ultra 5 245K consistently leads. Cinebench R15 multi-core shows 3850 against 2144, a 44.3% margin. Cinebench R20 multi-core shows 15368 versus 8935, a 41.9% margin. Cinebench R23 multi-core narrows the gap to 15.1%, with 25066 versus 21276. The smaller R23 gap suggests that the Core 7 253PTE scales better under extended multi-threaded loads relative to its own R15 and R20 results, though it still trails by a substantial degree.

Single-core results are more divided. Cinebench R15 single-core gives the Core Ultra 5 245K a narrow 322 to 302 win, a 6.2% margin. Cinebench R20 single-core extends that lead to 41.9%, with 2169 versus 1261. Yet Cinebench R23 single-core flips decisively: 3003 for the Core 7 253PTE versus 2132 for the Core Ultra 5 245K, a 40.9% advantage for the older part. This inconsistency across Cinebench versions points to different workload characteristics within the test suite; the R23 single-core test appears to favor the higher boost clock and possibly different cache behavior of the Core 7 253PTE.

PassMark tests show a similar pattern of Core Ultra 5 245K dominance with one notable exception. Data compression goes to the Core Ultra 5 245K at 458817 versus 275828, a 39.9% margin. Data encryption shows 33286 versus 15500, a 53.4% lead. Extended instructions give 37617 versus 17099, a 54.5% margin. Find prime numbers shows the largest gap at 414 versus 82, an 80.2% difference. Floating point math delivers 130678 versus 67209, a 48.6% lead. Physics simulation shows 3081 versus 1318, a 57.2% margin. Random string sorting goes 55098 versus 28227, a 48.8% lead.

The integer math test is where the Core 7 253PTE reclaims ground. Its score of 119552 beats 98524 for the Core Ultra 5 245K, a 21.3% margin. This is a notable reversal given the Core Ultra 5 245K's dominance in most other compute tests. The PassMark single-thread test, at 4714 versus 3794, gives the Core Ultra 5 245K a 19.5% advantage, consistent with most single-thread results except the R23 anomaly.

Specification Differences

The two processors differ across nearly every major specification category. The Core 7 253PTE uses 10 cores and 20 threads, while the Core Ultra 5 245K uses 14 cores and 14 threads. The Core Ultra 5 245K has more physical cores but no simultaneous multithreading, so its thread count is lower than its core count. The Core 7 253PTE uses hyper-threading to reach 20 threads from 10 cores.

Base clocks differ sharply. The Core 7 253PTE runs at 1.80 GHz base, while the Core Ultra 5 245K runs at 4.20 GHz base. Boost clocks reverse the order: 5.40 GHz for the Core 7 253PTE and 5.20 GHz for the Core Ultra 5 245K. The thermal design power also diverges: 45 watts for the Core 7 253PTE versus 125 watts for the Core Ultra 5 245K, indicating very different power envelopes and cooling requirements.

Sockets are incompatible. The Core 7 253PTE uses Intel Socket 1700, while the Core Ultra 5 245K uses Intel Socket 1851. Memory support differs as well: the Core 7 253PTE accepts both DDR4 and DDR5, while the Core Ultra 5 245K accepts DDR5 only. Memory bandwidth favors the Core Ultra 5 245K at 102.4 GB/s versus 89.6 GB/s. PCIe capabilities also differ, with 16 CPU lanes for the Core 7 253PTE and 20 CPU lanes for the Core Ultra 5 245K, both Gen 5.

The integrated graphics differ. The Core 7 253PTE carries UHD Graphics 730, while the Core Ultra 5 245K carries Arc Xe-LPG Graphics 64EU. The multiplier is locked on the Core 7 253PTE and unlocked on the Core Ultra 5 245K, meaning the latter allows user overclocking. The launch MSRP for the Core 7 253PTE is $384, and for the Core Ultra 5 245K it is $319.

Architecture Differences

The two processors come from different architectural generations and manufacturing processes. The Core 7 253PTE uses the Bartlett Lake codename, part of the Core 7 generation, and is built on a 10 nm process by Intel. The Core Ultra 5 245K belongs to the Core Ultra Series 2, uses the Arrow Lake architecture with the Arrow Lake-S codename, and is fabricated on a 3 nm process by TSMC. This process difference is significant: the Core Ultra 5 245K uses a smaller node from a different foundry, which contributes to its higher transistor density and efficiency profile.

The Core Ultra 5 245K lists 17,800 million transistors on a 243 mm² die. The Core 7 253PTE has no transistor count or die size recorded in the database. Cache hierarchies differ in both size and organization. The Core 7 253PTE has 80 KB of L1 per core and 2 MB of L2 per core, with 33 MB of shared L3. The Core Ultra 5 245K has 192 KB of L1 per core and 3 MB of L2 per core, with 24 MB of shared L3. The larger per-core caches on the Core Ultra 5 245K align with its lower core count per module, while the Core 7 253PTE compensates with a larger shared L3 pool.

Release dates place the Core Ultra 5 245K earlier, with a launch date of 2024-10-23, while the Core 7 253PTE launched later on 2026-03-08. Both processors are marked as Active in production status and target the desktop market segment. Both support ECC memory and dual-channel memory buses. The Core Ultra 5 245K has an unlocked multiplier, while the Core 7 253PTE does not. The recorded part numbers are SA4QK for the Core 7 253PTE and SRQCT for the Core Ultra 5 245K.
