Intel Core i5-13600KF vs Intel Core Ultra 5 245T Comparison

The Intel Core Ultra 5 245T and the Intel Core i5-13600KF are two desktop processors that, despite a similar core count, deliver distinctly different performance profiles. The data shows a clear split: the 13600KF dominates in most multi-threaded and legacy single-threaded workloads, while the 245T counters with specific wins in prime number calculation, floating-point math, and PassMark's single-thread test. Both processors hold an 86th percentile ranking among all CPUs, and their average benchmark scores are nearly identical, with the 245T at 38194 and the 13600KF at 38103.

Head-to-Head Benchmarks

The most decisive victories for the Intel Core i5-13600KF come in the Cinebench suite, where it consistently outperforms the Core Ultra 5 245T by a significant margin. In Cinebench R23, the 13600KF scores 31727 points in the multi-core test, which is 17.4% ahead of the 245T’s 26208. The single-core results follow the same pattern, with the 13600KF scoring 4479 versus the 245T’s 3699, also a 17.4% difference. This consistency extends to older versions of the benchmark; in Cinebench R20, the 13600KF leads by 17.4% in both single-core (1881 vs 1553) and multi-core (13325 vs 11007) tests. Cinebench R15 shows similar deltas, with the 13600KF scoring 3198 multi-core and 451 single-core, against the 245T’s 2641 and 372, respectively.

Outside of Cinebench, the 13600KF continues to widen the gap in several PassMark tests. The largest delta is in data compression, where the 13600KF scores 475505, a massive 40.3% improvement over the 245T’s 283812. Random string sorting also favors the 13600KF, which scores 50851, outperforming the 245T by 31.3%. In integer math, the 13600KF’s 122169 score is 27.4% higher than the 245T’s 88676. The 13600KF also demonstrates strong multi-threading capability, scoring 37488 in PassMark’s multithread test, an 17.8% advantage over the 245T’s 30833. Extended instructions see a 23.5% lead for the 13600KF (28865 vs 22071), and data encryption shows a 12.2% advantage with scores of 26957 versus 23656.

The Intel Core Ultra 5 245T, however, is not without its own decisive wins. Its most striking victory is in the PassMark find prime numbers test, where it scores 324, a staggering 113.2% higher than the 13600KF’s 152. In floating-point math, the 245T scores 108499, which is 20% ahead of the 13600KF’s 90424. The 245T also takes the PassMark single-thread test, scoring 4367, a 6% advantage over the 13600KF’s 4118. The margin is much slimmer in the physics test, where the 245T scores 2278, just 2.3% above the 13600KF’s 2226.

The outcome is lopsided in terms of total wins, with the 13600KF taking 12 benchmark victories compared to the 245T’s 5. However, the nature of those wins is telling. The 13600KF’s victories are often large, particularly in compression and integer math, while the 245T’s wins are either extremely large in a single niche test or more modest in general-purpose tests. The 245T’s win in the PassMark single-thread test is notable, as it suggests a different architectural strength that does not translate to Cinebench single-core performance.

The Verdict

The data presents a straightforward choice for most users. The Intel Core i5-13600KF is the superior processor for the majority of demanding workloads. Its consistent 17.4% lead across the entire Cinebench series indicates a strong advantage in rendering and other CPU-intensive tasks that utilize these benchmarks. The 40.3% lead in data compression and 27.4% lead in integer math make it the clear choice for file archiving, code compilation, and general productivity software that relies on such operations. Its 17.8% lead in the multithread test reinforces its strength in fully threaded applications.

The Intel Core Ultra 5 245T is the better option in a narrow set of scenarios. The 113.2% lead in prime number finding is a specific, but real, win for certain scientific and mathematical workloads. The 20% lead in floating-point math also points to an advantage in scientific simulations and 3D modeling that depend heavily on floating-point calculations. Furthermore, the 6% lead in PassMark’s single-thread test suggests it has a slight edge in lightly threaded applications that are not measured by Cinebench. The 245T’s 2.3% win in physics is negligible in practical terms.

For a user building a general-purpose desktop or a workstation for rendering, the 13600KF is the data-backed pick. Its broad and substantial leads in most benchmarks, particularly Cinebench, make it the more versatile and powerful choice. The 245T is only preferable for a user with a specific, known workload that matches its niche strengths: prime number computation, floating-point-heavy tasks, and the specific PassMark single-thread test. The 13600KF’s unlocked multiplier also gives it potential for manual overclocking, a feature the 245T lacks, though the data here does not quantify that potential.

Specification Differences

The two processors differ in several key specifications. The Intel Core Ultra 5 245T has 14 threads, while the Intel Core i5-13600KF has 20 threads, despite both having 14 cores. The base clock speed of the 245T is 2.20 GHz, which is lower than the 13600KF’s 3.50 GHz; however, both have an identical boost clock of 5.10 GHz. The 245T has a TDP of 65 watts, whereas the 13600KF has a TDP of 125 watts. They use different sockets, with the 245T on Intel Socket 1851 and the 13600KF on Intel Socket 1700.

Their memory support also differs. The 245T supports only DDR5 memory, while the 13600KF supports both DDR4 and DDR5. The 245T has a listed memory bandwidth of 102.4 GB/s, a figure not provided for the 13600KF. The 245T supports 20 PCIe Gen 5 lanes (CPU only), compared to 16 lanes for the 13600KF. The 245T includes integrated Arc Xe-LPG Graphics with 64 execution units, while the 13600KF has no integrated graphics listed. Finally, the 245T has a locked multiplier, while the 13600KF has an unlocked multiplier for overclocking.

Architecture Differences

The architectural designs are fundamentally different. The Intel Core Ultra 5 245T is from the Core Ultra Series 2 and uses the Arrow Lake-S architecture on a 3 nm process node fabricated by TSMC, with a die size of 243 mm² and 17,800 million transistors. Its cache layout includes 192 KB of L1 cache per core, 3 MB of L2 cache per core, and 24 MB of shared L3 cache. It was released in 2025.

In contrast, the Intel Core i5-13600KF is from the Core 13th Gen series and uses the Raptor Lake-S architecture on a 10 nm process node fabricated by Intel, with a die size of 257 mm². Its cache is smaller per core, with 80 KB of L1 cache and 2 MB of L2 cache per core, but it also has 24 MB of shared L3 cache. It was released in 2022. The combination of a newer, denser process node and different cache hierarchy in the 245T explains its efficiency and specific performance wins, while the 13600KF’s older architecture with more threads delivers higher raw throughput in most tests.
