The average benchmark scores place these processors in different performance strata. The Core Ultra 5 250K Plus averages 66,855 across all recorded tests, while the Core 7 160UL averages 14,232. This corresponds to a 93rd percentile ranking among all CPUs for the Core Ultra 5 250K Plus, versus a 69th percentile for the Core 7 160UL. The nearest rivals in the database confirm this positioning: the Core Ultra 5 250K Plus sits within 1.1% of the Intel Core Ultra 5 250KF Plus, while the Core 7 160UL trades within 0.6% of the AMD Ryzen 5 3501U.

Architecture Differences

The architectural gap between these two processors is fundamental. The Intel Core 7 160UL uses Raptor Lake architecture with the Raptor Lake-PS codename, fabricated on Intel's 10 nm process. The Intel Core Ultra 5 250K Plus belongs to the Core Ultra Series 2 with the Arrow Lake Refresh codename, built on TSMC's 3 nm process. This process difference contributes to the transistor density and efficiency characteristics: the Arrow Lake Refresh die contains 17,800 million transistors on a 243 mm² die, while the Raptor Lake-PS die size and transistor count are not recorded in the database.

Core and thread configurations differ sharply. The Core 7 160UL provides 10 cores and 12 threads, indicating a hybrid arrangement with some cores lacking simultaneous multithreading. The Core Ultra 5 250K Plus provides 18 cores and 18 threads, suggesting all cores operate without multithreading. This 8-core and 6-thread advantage explains much of the multi-core benchmark disparity.

Cache hierarchies scale accordingly. The Core 7 160UL has 80 KB of L1 cache per core, 1.25 MB of L2 per core, and 12 MB of shared L3 cache. The Core Ultra 5 250K Plus more than doubles each level: 192 KB L1 per core, 3 MB L2 per core, and 30 MB shared L3. The L3 cache difference alone, 30 MB versus 12 MB, contributes to the Core Ultra 5's advantage in cache-sensitive workloads like data compression and random string sorting.

Clock speeds also favor the Core Ultra 5 250K Plus. Its base clock is 4.20 GHz and boost clock is 5.30 GHz, compared to 1.80 GHz base and 5.20 GHz boost for the Core 7 160UL. The base clock difference is particularly large, 2.40 GHz, which affects sustained workloads. The boost clock difference is smaller, 0.10 GHz, yet the single-core benchmarks still show a 28.7% to 78.6% advantage for the Core Ultra 5 depending on the test.

Memory support differs in scope and speed. The Core 7 160UL supports both DDR4 and DDR5 memory, while the Core Ultra 5 250K Plus supports only DDR5. Both use dual-channel memory buses, but the Core Ultra 5 250K Plus records a memory bandwidth of 115.2 GB/s, a figure not listed for the Core 7 160UL. ECC memory support is present on the Core Ultra 5 250K Plus but absent on the Core 7 160UL.

PCIe connectivity shows a generational leap. The Core 7 160UL provides PCIe Gen 4 with 8 lanes from the CPU. The Core Ultra 5 250K Plus provides PCIe Gen 5 with 20 lanes from the CPU. This affects expansion bandwidth for graphics and storage devices.

Integrated graphics also differ. The Core 7 160UL uses Iris Xe Graphics with 96 execution units. The Core Ultra 5 250K Plus uses Arc Xe-LPG Graphics with 64 execution units. The Core 7 160UL has more execution units, but the Core Ultra 5's newer architecture likely changes efficiency characteristics.

Sockets and release timing separate the platforms. The Core 7 160UL uses Intel Socket 1700 and was released on 2024-04-07. The Core Ultra 5 250K Plus uses Intel Socket 1851 and was released on 2026-03-10. The Core Ultra 5 250K Plus has an unlocked multiplier, while the Core 7 160UL does not, enabling overclocking on the former.

The Verdict

The recorded data supports a clear performance hierarchy. The Intel Core Ultra 5 250K Plus outperforms the Intel Core 7 160UL in every single benchmark test, with margins from 28.7% to 89.7%. The Core Ultra 5 250K Plus ranks in the 93rd percentile of all CPUs, while the Core 7 160UL sits in the 69th percentile. The average benchmark score for the Core Ultra 5 250K Plus is 66,855, approximately 4.7 times the Core 7 160UL's 14,232.

The architectural differences explain this gap. The Core Ultra 5 250K Plus combines a 3 nm TSMC process, 18 cores, 30 MB of L3 cache, higher base and boost clocks, and DDR5-only memory with 115.2 GB/s bandwidth. The Core 7 160UL uses a 10 nm Intel process, 10 cores, 12 MB of L3 cache, a 1.80 GHz base clock, and supports both DDR4 and DDR5.

The Core 7 160UL's advantages are limited to specific characteristics recorded in the database. It has a much lower TDP of 15 W versus 125 W, making it suitable for thermally constrained systems. It supports DDR4 memory, which may ease upgrade paths for existing platforms. Its integrated graphics use 96 execution units versus 64, though this does not translate into any benchmark advantage in the recorded tests. The Core 7 160UL also uses the more widely established Socket 1700 platform.

Users selecting between these processors should base decisions on the benchmark evidence. The Core Ultra 5 250K Plus delivers superior performance across rendering, encryption, compression, and general compute workloads. The Core 7 160UL offers a lower-power alternative with legacy memory support, but its performance ceiling is substantially lower in every measured category.

Where Each One Wins

The Intel Core Ultra 5 250K Plus wins in all 17 recorded benchmark comparisons. Its largest margins come in prime number finding (89.7% ahead), extended instructions (86.9%), floating point math (84.2%), and data encryption (83%). These results indicate strong performance in computational mathematics, encryption workloads, and floating-point-heavy applications.

The Core Ultra 5 250K Plus also leads decisively in rendering workloads. Cinebench R20 multi-core shows a 78.6% advantage, Cinebench R15 multi-core shows a 79.6% advantage, and Cinebench R23 multi-core shows a 69.6% advantage. These are among the largest gaps in the multi-core tests, confirming that the additional 8 cores and larger cache directly benefit multi-threaded rendering.

Data compression and random string sorting favor the Core Ultra 5 250K Plus by 80.8% and 82.9% respectively. The 30 MB shared L3 cache versus 12 MB likely contributes to these results. Integer math shows the smallest Passmark gap at 62%, while single-thread Passmark shows the overall smallest gap at 28.7%.

The Core 7 160UL has no recorded benchmark wins. Its performance profile is closer to the Core Ultra 5 250K Plus in single-threaded Passmark tests, where the 28.7% gap is the narrowest. This suggests that for lightly threaded workloads with modest demands, the Core 7 160UL can keep pace better than in heavily multi-threaded scenarios.

For use cases, the data points to clear divisions. The Core Ultra 5 250K Plus suits multi-core rendering, data compression, encryption, and floating-point computation. The Core 7 160UL suits scenarios where its 15 W TDP and DDR4 support matter more than raw throughput, such as compact or power-sensitive desktop systems. Neither processor shows any advantage in the recorded benchmarks for the other, so workload selection should follow the performance evidence directly.
