Architecture Differences

The Intel Core 7 253PTE is built on Bartlett Lake silicon, using a 10 nm process node from Intel's own foundry. It adopts a hybrid configuration with 10 cores and 20 threads, indicating simultaneous multithreading support. Its cache hierarchy includes 80 KB of L1 per core, 2 MB of L2 per core, and 33 MB of shared L3 cache. The processor runs on Intel Socket 1700 and supports both DDR4 and DDR5 memory in a dual-channel configuration, with a memory bandwidth of 89.6 GB/s. Integrated graphics come in the form of UHD Graphics 730.

The Intel Core Ultra 5 245 belongs to the Core Ultra Series 2 and uses Arrow Lake architecture, specifically the Arrow Lake-S codename. It is manufactured on a 3 nm process node by TSMC, with 17,800 million transistors on a 243 mm² die. This processor provides 14 cores and 14 threads, meaning it does not use hyperthreading. Cache amounts are larger per core: 192 KB of L1, 3 MB of L2, but the shared L3 is smaller at 24 MB. It uses Intel Socket 1851 and supports only DDR5 memory, dual-channel, with a memory bandwidth of 102.4 GB/s. The integrated graphics are Arc Xe-LPG Graphics 64EU. ECC memory support is present in both processors.

The difference in thread count is notable: the Core 7 253PTE delivers 20 threads from 10 cores, while the Core Ultra 5 245 delivers 14 threads from 14 cores. The Core Ultra 5 245 compensates for fewer threads per core with a higher base clock of 3.50 GHz versus 1.80 GHz, and a smaller process node. The Core 7 253PTE has a higher boost clock at 5.40 GHz versus 5.10 GHz. The L3 cache difference is significant as well, with the Core 7 253PTE carrying 33 MB shared versus 24 MB for the Core Ultra 5 245. Both processors lack an unlocked multiplier.

Head-to-Head Benchmarks

The benchmark data shows a dominant performance profile for the Intel Core Ultra 5 245 across nearly every measured workload. In Cinebench R15 multi-core, the Core Ultra 5 245 scores 3318 versus 2144 for the Core 7 253PTE, a deficit of -35.4% for the latter. The single-core R15 result follows the same pattern: 468 versus 302, also -35.5%. Cinebench R20 multi-core shows 13828 versus 8935, again -35.4%, and single-core R20 shows 1952 versus 1261, also -35.4%. In Cinebench R23, the multi-core score is 32924 versus 21276, and single-core is 4648 versus 3003, both with a -35.4% delta.

PassMark tests reinforce the Core Ultra 5 245 advantage. Data compression scores 400942 versus 275828, a -31.2% gap. Data encryption shows 30236 versus 15500, a -48.7% gap. Extended instructions score 33304 versus 17099, also -48.7%. The prime number search workload shows the largest relative gap: 365 versus 82, a -77.5% difference. Floating point math delivers 120548 versus 67209, a -44.2% gap. Multithread performance is 38706 versus 25031, a -35.3% gap. Physics simulation scores 2569 versus 1318, a -48.7% gap. Random string sorting shows 49140 versus 28227, a -42.6% gap. Single-thread performance is 4394 versus 3794, a -13.7% gap.

The single exception is integer math, where the Core 7 253PTE scores 119552 versus 91187 for the Core Ultra 5 245, giving the former a 31.1% advantage. This result indicates that the older 10 nm design retains strength in pure integer arithmetic operations despite losing nearly every other comparison.

Specification Differences

The two processors diverge on several specification fields. The Core 7 253PTE has 10 cores and 20 threads, while the Core Ultra 5 245 has 14 cores and 14 threads. Base clocks differ: 1.80 GHz for the Core 7 253PTE versus 3.50 GHz for the Core Ultra 5 245. Boost clocks also differ: 5.40 GHz versus 5.10 GHz. Thermal design power is 45 watts for the Core 7 253PTE and 65 watts for the Core Ultra 5 245.

Socket compatibility is distinct: Intel Socket 1700 for the Core 7 253PTE, Intel Socket 1851 for the Core Ultra 5 245. The architecture and codename differ as well: Bartlett Lake for the former, Arrow Lake-S for the latter. Process nodes are 10 nm (Intel foundry) versus 3 nm (TSMC foundry). Transistor count and die size are reported only for the Core Ultra 5 245: 17,800 million and 243 mm², respectively.

Cache configurations differ in all three levels. L1 is 80 KB per core versus 192 KB per core. L2 is 2 MB per core versus 3 MB per core. L3 is 33 MB shared versus 24 MB shared. Memory support differs: DDR4 and DDR5 for the Core 7 253PTE, DDR5 only for the Core Ultra 5 245. Memory bandwidth is higher for the Core Ultra 5 245 at 102.4 GB/s versus 89.6 GB/s. PCIe lane count differs: 16 lanes for the Core 7 253PTE versus 20 lanes for the Core Ultra 5 245. Integrated graphics differ: UHD Graphics 730 versus Arc Xe-LPG Graphics 64EU. The launch MSRP is $384 for the Core 7 253PTE and $270 for the Core Ultra 5 245. Release dates differ as well: the Core 7 253PTE launched in March 2026, while the Core Ultra 5 245 launched in January 2025. Both processors are active in production, both are desktop market segment, both support ECC memory, and both are multiplier-unlocked false.

Where Each One Wins

The Intel Core Ultra 5 245 wins in virtually every measured category. It leads in all Cinebench tests, including both multi-core and single-core versions of R15, R20, and R23. It also leads in PassMark data compression, encryption, extended instructions, prime number search, floating point math, multithread, physics, random string sorting, and single-thread tests. The average benchmark score of 48995 places it in the 90th percentile, far above the 34962 average of the Core 7 253PTE, which sits in the 84th percentile.

The Core 7 253PTE claims one clear victory in PassMark integer math, scoring 119552 versus 91187. This workload appears to benefit from the higher boost clock of 5.40 GHz and the larger 33 MB L3 cache, even though the processor runs on a larger process node. The 10-core, 20-thread configuration with SMT may also contribute to integer throughput.

For workloads that depend on single-core responsiveness, the Core Ultra 5 245 is the stronger option. Its single-thread PassMark score of 4394 versus 3794, a 13.7% advantage, and Cinebench R23 single-core score of 4648 versus 3003, confirm this. The higher base clock of 3.50 GHz allows the Core Ultra 5 245 to maintain performance without relying on boost states as heavily.

For memory bandwidth-sensitive applications, the Core Ultra 5 245 again takes the lead with 102.4 GB/s versus 89.6 GB/s. The dual-channel DDR5-only support enables this higher throughput. The Core 7 253PTE retains flexibility with DDR4 support, but that compatibility comes at the cost of bandwidth. The Core Ultra 5 245 also offers more PCIe lanes at 20 versus 16, which benefits systems with multiple expansion devices.

The Core 7 253PTE remains competitive in integer-heavy tasks and provides a lower thermal design power of 45 watts versus 65 watts. That lower TDP could appeal to systems with tighter cooling constraints, though benchmark results indicate the Core Ultra 5 245 delivers substantially higher performance across the broader workload set. The Core 7 253PTE also supports both DDR4 and DDR5, which offers platform memory flexibility that the DDR5-only Core Ultra 5 245 does not provide.
