Intel Core i5-14600 vs Intel Core Ultra 9 285 Comparison

The Intel Core i5-14600 and the Intel Core Ultra 9 285 occupy opposite ends of Intel’s desktop lineup, and the benchmark data reflects a decisive gap in performance. The Core Ultra 9 285 wins every single recorded test, 17 out of 17, with no victories for the Core i5-14600. This is not a close contest; it is a clear hierarchy where the newer, larger Arrow Lake processor dominates across every measured workload. The data shows a consistent performance tier separation, with the Core Ultra 9 285 delivering roughly a third more performance in most multi-threaded tasks and a smaller but still significant edge in single-threaded work.

Where Each One Wins

The Core Ultra 9 285 wins in every category represented in the database, but the magnitude of its advantage varies sharply by workload type. For multi-threaded rendering tasks, the lead is overwhelming. In Cinebench R23 multi-core, the Core Ultra 9 285 scores 48945 against 30464 for the Core i5-14600, a delta of 37.8 percent. The same pattern holds across Cinebench R15 and R20 multi-core tests, where the delta remains at 37.8 percent. This indicates that the Core Ultra 9 285’s additional cores and threads translate directly into sustained rendering performance.

The single-core results show a similar directional advantage but a smaller gap. In Cinebench R23 single-core, the Core Ultra 9 285 scores 6909 versus 4300, a 37.8 percent lead. That is a substantial margin, but in PassMark single-thread tests, the advantage shrinks to 14.6 percent, with scores of 4881 and 4167. The PassMark suite measures a broader mix of instructions, and the Core Ultra 9 285 still wins, but the gap narrows, suggesting the Core i5-14600’s high boost clock of 5.20 GHz helps it remain competitive in lighter single-threaded workloads.

Where the Core Ultra 9 285 truly separates itself is in specialized compute tasks. The largest delta is in PassMark find prime numbers, where the Core Ultra 9 285 scores 459 versus 155, a 66.2 percent advantage. Floating-point math also shows a massive gap, 194988 versus 85759, a 56 percent lead. Data encryption and extended instructions follow with deltas of 46.6 percent and 43.4 percent respectively. These results indicate that the Core Ultra 9 285 is not just faster, it is fundamentally more efficient at executing complex mathematical and cryptographic workloads.

The Core i5-14600 finds no winning scenario in the recorded data. Its only relative strength is in single-threaded PassMark tests, where the 14.6 percent deficit is the smallest of any benchmark. For users whose workloads are dominated by light, sequential tasks, the Core i5-14600 is closer to the Core Ultra 9 285, but it still loses every test. The data offers no case where the Core i5-14600 outperforms its rival.

Architecture Differences

The two processors come from different architectural generations and manufacturing processes. The Core i5-14600 is built on Raptor Lake, specifically the Raptor Lake Refresh generation, using Intel’s 10 nm process node. The Core Ultra 9 285 uses Arrow Lake, the Arrow Lake-S generation, fabricated by TSMC on a 3 nm node. This process difference is significant, as the 3 nm node allows for higher transistor density and better power efficiency, which is reflected in the Core Ultra 9 285’s higher performance at the same 65 W TDP.

The core configurations are also fundamentally different. The Core i5-14600 has 14 cores and 20 threads, meaning it uses a hybrid layout with performance and efficiency cores where some cores support hyper-threading. The Core Ultra 9 285 has 24 cores and 24 threads, indicating a design without hyper-threading, where each core is a physical thread. The Core Ultra 9 285’s higher core count is the primary driver of its multi-threaded dominance.

Cache hierarchies differ considerably. The Core i5-14600 has 80 KB of L1 cache per core, 2 MB of L2 per core, and 24 MB of shared L3 cache. The Core Ultra 9 285 has 192 KB of L1 per core, 3 MB of L2 per core, and 36 MB of shared L3. The larger per-core caches and the 50 percent larger L3 pool give the Core Ultra 9 285 a clear advantage in workloads that benefit from data locality, such as the PassMark extended instructions and random string sorting tests.

Memory support is another differentiator. The Core i5-14600 supports both DDR4 and DDR5, while the Core Ultra 9 285 supports only DDR5. The Core Ultra 9 285 also lists a memory bandwidth of 102.4 GB/s, a figure not provided for the Core i5-14600. Both processors support ECC memory and use a dual-channel memory bus. The Core Ultra 9 285 also offers more PCIe lanes, 20 Gen 5 lanes versus 16 Gen 5 lanes on the Core i5-14600.

The integrated graphics differ as well. The Core i5-14600 uses UHD Graphics 770, while the Core Ultra 9 285 uses Arc Xe-LPG Graphics with 64 execution units. The socket also changes, with the Core i5-14600 on Intel Socket 1700 and the Core Ultra 9 285 on Intel Socket 1851. The Core Ultra 9 285 is a larger die at 243 mm² with 17,800 million transistors, compared to the Core i5-14600’s 257 mm² die, though the transistor count for the Core i5-14600 is not recorded. The Core Ultra 9 285 also has a higher boost clock of 5.60 GHz versus 5.20 GHz, and a lower base clock of 2.50 GHz versus 2.70 GHz.

Head-to-Head Benchmarks

The Cinebench suite shows a consistent 37.8 percent advantage for the Core Ultra 9 285 across R15, R20, and R23, for both single-core and multi-core tests. In Cinebench R15 multi-core, the scores are 4933 and 3070. R15 single-core is 696 and 433. R20 multi-core is 20556 and 12794. R20 single-core is 2901 and 1806, a 37.7 percent delta. R23 multi-core is 48945 and 30464, and R23 single-core is 6909 and 4300. The uniformity of this delta suggests the architectural advantage is consistent across different Cinebench versions.

The PassMark suite provides a more varied picture. The largest win for the Core Ultra 9 285 is in find prime numbers, where it scores 459 against 155, a 66.2 percent lead. This test is highly sensitive to integer arithmetic and branch prediction, where the newer architecture excels. Floating-point math shows a 56 percent advantage, with scores of 194988 and 85759. Data encryption shows a 46.6 percent gap, with 46949 versus 25082. Extended instructions show a 43.4 percent gap, with 45357 versus 25674.

Data compression is a more moderate win, with the Core Ultra 9 285 scoring 602121 versus 434620, a 27.8 percent lead. Integer math shows a 29 percent gap, with 164869 versus 117078. Multi-threaded PassMark shows a 36.7 percent gap, with 56602 versus 35848. Physics shows a 35.2 percent gap, with 3598 versus 2330. Random string sorting shows a 34.8 percent gap, with 73651 versus 48043.

The smallest margin is in single-threaded PassMark, where the Core Ultra 9 285 scores 4881 versus 4167, a 14.6 percent lead. This is the only benchmark where the gap is below 20 percent, indicating that the Core i5-14600’s high boost clock and mature architecture keep it relatively close in lightly threaded tasks. Even so, the Core Ultra 9 285 wins this test, confirming its superiority across all recorded metrics.

The Verdict

The data is unambiguous: the Intel Core Ultra 9 285 is the faster processor in every measured workload. Its 17 wins out of 17 benchmarks, combined with its 95th percentile ranking versus all CPUs, places it in a different performance class than the Core i5-14600, which sits at the 89th percentile. The average benchmark score of 75488 for the Core Ultra 9 285 is substantially higher than the 44889 for the Core i5-14600.

For users whose workloads are heavily multi-threaded, such as rendering, video encoding, or scientific computing, the Core Ultra 9 285 is the clear choice, offering a 37.8 percent advantage in Cinebench multi-core tests. For users who prioritize single-threaded performance, the Core Ultra 9 285 still wins, but the 14.6 percent gap in PassMark single-thread is smaller. The Core i5-14600 remains a capable processor for light desktop use, but the recorded data shows no workload where it outperforms the Core Ultra 9 285.

The architecture differences reinforce this verdict. The Core Ultra 9 285’s 3 nm process, 24 cores, larger caches, and dedicated DDR5 support all contribute to its dominance. The Core i5-14600’s support for DDR4 and lower core count limit its ceiling. The Core Ultra 9 285 is the superior processor for any application that demands maximum compute throughput.
