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

The database tells a lopsided story: the Intel Core Ultra 9 285T beats the Intel Core i5-14600KF in 14 of 17 recorded head-to-head benchmarks, and it does so while drawing a 35 W TDP against a 125 W rating. The i5-14600KF claws back wins in data compression, string sorting, and extended instruction tests, but the overall picture favors the newer Arrow Lake chip in nearly every workload that matters for sustained compute. Both sit in the same performance neighborhood overall, at the 91st and 90th percentiles of all CPUs respectively, yet the details split cleanly along architectural and power-efficiency lines.

Where Each One Wins

The Core Ultra 9 285T dominates anything that leans on floating point throughput, encryption, physics simulation, or pure prime computation. Its floating point math score of 137923 against 93048 for the i5-14600KF is a 48.2 percent advantage, and the find prime numbers result more than doubles the rival, 345 versus 161, a 114.3 percent gap. Passmark physics lands 16 percent in its favor at 2842 versus 2449, and encryption is 16.1 percent ahead at 32061 versus 27608. Rendering also goes to the 285T: every Cinebench version in the database, R15, R20, and R23, in both single-core and multi-core modes, favors it by a consistent 3.2 percent.

The i5-14600KF wins where memory-bound integer throughput and specialized instruction paths carry the load. Data compression is its standout, 485140 versus 384140, a 20.8 percent lead for the Raptor Lake Refresh part. Random string sorting also goes its way at 52056 versus 47695, an 8.4 percent edge, and extended instructions favor it by 4.5 percent, 28785 versus 27477. These three wins are real but narrow, and they sit inside an otherwise one-sided record.

Single-threaded responsiveness favors the 285T by a meaningful margin. Passmark single-thread reads 4576 against 4273, a 7.1 percent advantage, larger than its 3.2 percent rendering leads, which suggests snappier per-task behavior in lightly threaded applications.

The Verdict

The data points to the Core Ultra 9 285T for almost everyone comparing these two directly. It wins 14 of 17 benchmarks, holds a higher average benchmark score of 51310 versus 49394, ranks in the 91st percentile against 90, and does all of it at roughly a quarter of the TDP, 35 W versus 125 W. For compact builds, efficiency-sensitive systems, or anyone running sustained floating point, encryption, physics, or rendering workloads, the 285T is the clear database pick.

The i5-14600KF still has a defensible case, but only for a specific profile: workloads dominated by compression, string sorting, or the extended instruction paths where it holds double-digit or solid leads. It also offers an unlocked multiplier for overclocking, which the 285T lacks, and it landed in the database with a launch MSRP of $294 versus $549 for the 285T. Both figures are launch MSRPs recorded once here. If tuning headroom and those specific workload wins matter more than raw breadth of performance, the 14600KF remains viable.

One platform note cuts the other way: the 285T uses Socket 1851 and ships with Arc Xe-LPG 64EU integrated graphics, while the 14600KF uses Socket 1700, has no integrated graphics in the database record, and therefore requires a discrete card.

Head-to-Head Benchmarks

Start with the biggest gap. In Passmark find prime numbers, the 285T scores 345 against 161, a 114.3 percent win, the largest delta in the entire dataset. Floating point math is nearly as dramatic: 137923 versus 93048, 48.2 percent ahead. Any workload built on numerical computation belongs firmly to the Arrow Lake chip.

Encryption and physics follow the same pattern. The 285T encrypts at 32061 versus 27608, up 16.1 percent, and posts 2842 in physics against 2449, up 16 percent. Integer math also goes to the 285T, 132433 versus 125982, a 5.1 percent edge.

Rendering is a sweep. Cinebench R23 multi-core reads 33573 versus 32544, R20 multi-core 14100 versus 13668, and R15 multi-core 3384 versus 3280, all 3.2 percent wins. Single-core rendering mirrors it exactly: 4739 versus 4594 in R23, 1990 versus 1929 in R20, 477 versus 462 in R15, each a 3.2 percent 285T win. Passmark multithread matches at 39931 versus 38697, again 3.2 percent.

The 14600KF's counterpunch is sharpest in data compression, where it scores 485140 versus 384140, a 20.8 percent lead and the biggest single win for either chip in absolute percentage terms outside the prime number test. String sorting goes its way too, 52056 versus 47695 for an 8.4 percent edge, and extended instructions land at 28785 versus 27477, 4.5 percent in its favor.

Single-thread belongs to the 285T at 4576 versus 4273, 7.1 percent ahead, a wider margin than its rendering leads and a useful indicator for latency-sensitive desktop tasks.

Architecture Differences

These are two different Intel eras. The 285T is an Arrow Lake-S design from Core Ultra Series 2, built on a 3 nm TSMC process with 17,800 million transistors packed into a 243 mm² die. The 14600KF is Raptor Lake-R from the 14th Gen family, built on Intel's own 10 nm process with a 257 mm² die and no transistor count recorded.

The core topology diverges sharply. The 285T pairs 24 cores with 24 threads, an all-physical-core layout with no hyperthreading. The 14600KF runs 14 cores and 20 threads, relying on SMT to reach its thread count from a smaller core base. Despite the 285T's much lower 1.40 GHz base clock versus 3.50 GHz, its 5.40 GHz boost tops the 14600KF's 5.30 GHz.

Cache heavily favors the 285T: 192 KB of L1 per core and 3 MB of L2 per core, against 80 KB and 2 MB respectively on the 14600KF, plus 36 MB of shared L3 versus 24 MB. That cache advantage helps explain the sustained leads in floating point and physics workloads.

Platform features also differ. The 285T provides 20 CPU PCIe Gen 5 lanes against 16 on the 14600KF, DDR5-only memory with 102.4 GB/s of bandwidth, and integrated Arc Xe-LPG graphics with 64 EUs. The 14600KF supports both DDR4 and DDR5, giving it broader memory compatibility, but has no recorded integrated graphics. Both support ECC and both remain in active production. Release timing separates them too: the 14600KF entered the database in October 2023, the 285T in January 2025.
