Intel Core i7-13700KF vs Intel Core Ultra 5 235A Comparison

Intel Core Ultra 5 235A vs Intel Core i7-13700KF: two desktop processors from different Intel generations, separated by roughly three years of design evolution. The database records 17 head-to-head benchmark comparisons, with the older Core i7-13700KF winning 13 of them and the newer Core Ultra 5 235A taking four. The aggregate picture is close: the Ultra 5 235A posts an average benchmark score of 48201 against the i7-13700KF's 47330, a difference of about 1.8 percent. Yet the individual workloads tell a more nuanced story, one where the newer chip wins specific math-heavy tasks while the older chip dominates nearly everything else.

Where Each One Wins

The Intel Core Ultra 5 235A wins in exactly four recorded tests: PassMark find prime numbers, floating point math, single thread, and singlethread (the latter two are the same score recorded under two names). Its 110.8 percent advantage in find prime numbers is the single largest margin in the entire comparison. That workload, which stresses integer recursion and branch prediction, appears to be a particular strength of the Arrow Lake architecture. The 3.3 percent edge in floating point math is smaller but still a clear win, and the 5.1 percent lead in single-threaded PassMark tests shows the newer chip's per-core efficiency.

The Intel Core i7-13700KF wins everywhere else. Its margins range from a modest 8 percent in PassMark physics to a crushing 42.6 percent in integer math. The older chip also leads by 34 percent in data compression, 21.1 percent in random string sorting, and 16.2 percent in multithread. All six Cinebench tests go to the i7-13700KF by nearly identical margins of 15.6 to 15.7 percent. The pattern is clear: if the workload is heavily threaded, compression-based, or integer-heavy, the i7-13700KF is the pick. If the workload involves prime number calculation, floating point math, or lightly threaded PassMark tasks, the Ultra 5 235A takes the lead.

Architecture Differences

The two chips represent fundamentally different design philosophies. The Core Ultra 5 235A uses Arrow Lake-S architecture built on a 3 nm process at TSMC, packing 14 cores and 14 threads with no hyperthreading. The Core i7-13700KF uses Raptor Lake-S on Intel's 10 nm process, with 16 cores and 24 threads thanks to hyperthreading on its performance cores. The transistor counts tell part of the story: the Ultra 5 has 17,800 million transistors on a 243 mm² die, while the i7-13700KF's die is slightly larger at 257 mm² but its transistor count is not recorded in the database.

Cache hierarchies differ notably. The Ultra 5 235A provides 192 KB of L1 per core, 3 MB of L2 per core, and 24 MB of shared L3. The i7-13700KF has 80 KB L1 per core, 2 MB L2 per core, and a larger 30 MB shared L3. The newer chip's larger per-core L1 and L2 should help with latency-sensitive workloads, which likely contributes to its single-thread PassMark win.

Memory support also diverges. The Ultra 5 235A supports only DDR5 with a recorded memory bandwidth of 102.4 GB/s. The i7-13700KF supports both DDR4 and DDR5, and its memory bandwidth is not recorded in the database. ECC memory is supported on the i7-13700KF but not on the Ultra 5 235A. Both use dual-channel memory and PCIe Gen 5 with 20 CPU lanes.

The i7-13700KF has an unlocked multiplier, making it overclockable, while the Ultra 5 235A is locked. The i7-13700KF also boosts higher, to 5.40 GHz versus 5.00 GHz for the Ultra 5, though both have the same 3.40 GHz base clock. TDP differs significantly: the i7-13700KF is rated at 125 watts, the Ultra 5 235A at 65 watts. The Ultra 5 235A includes integrated Arc Xe-LPG Graphics with 24 execution units; the i7-13700KF has no integrated graphics. The Ultra 5 uses Intel Socket 1851, while the i7-13700KF uses Socket 1700.

Head-to-Head Benchmarks

The Cinebench results are remarkably consistent. Every Cinebench test, from R15 to R23, single and multi-core, shows the i7-13700KF winning by 15.6 or 15.7 percent. In R23 multi-core, the i7-13700KF scores 38704 against the Ultra 5's 32633. In R23 single-core, the older chip scores 5464 versus 4607. This uniformity suggests the i7-13700KF's extra threads and higher boost clock provide a steady advantage across rendering workloads.

PassMark tests reveal the split more dramatically. The i7-13700KF wins data compression 596493 to 393800, a 34 percent gap, and integer math 154507 to 88626, a 42.6 percent gap. Random string sorting goes 62726 to 49489, a 21.1 percent edge. Multithread goes 45817 to 38392, a 16.2 percent margin. Physics goes 2650 to 2437, an 8 percent edge. Data encryption goes 33314 to 30136, a 9.5 percent margin. Extended instructions go 36700 to 31625, a 13.8 percent edge.

The Ultra 5 235A's wins are narrower except for prime numbers. It scores 392 in find prime numbers versus 186 for the i7-13700KF, a 110.8 percent blowout. Floating point math goes 118778 to 114997, a 3.3 percent win. Single-thread PassMark goes 4557 to 4336, a 5.1 percent win. These are the only bright spots for the newer chip, but they are real and consistent across two different PassMark single-thread entries.

In the broader database context, the Ultra 5 235A sits at the 90th percentile among all CPUs, with an average benchmark score of 48201. Its closest rivals include the AMD Ryzen AI Max PRO 380 at 48171 (0.1 percent ahead), the Intel Core Ultra 5 245HX at 48287 (0.2 percent behind), the AMD EPYC 4345P at 48470 (0.6 percent behind), and the AMD Ryzen 9 3900 at 47918 (0.6 percent ahead). The i7-13700KF sits at the 89th percentile with an average score of 47330. Its nearest rivals are the Intel Core Ultra X9 378H at 47468 (0.3 percent behind), the Intel Core i9-12900F at 47176 (0.3 percent ahead), the AMD Ryzen 9 PRO 5945 at 47527 (0.4 percent behind), and the AMD Ryzen AI 9 HX PRO 375 at 47022 (0.7 percent ahead).

FAQ

Q: Which processor is faster in single-threaded performance?

A: The Core Ultra 5 235A wins the PassMark single-thread test with a score of 4557 versus 4336 for the i7-13700KF, a 5.1 percent advantage. However, the i7-13700KF wins Cinebench R23 single-core with 5464 against 4607, a 15.7 percent margin.

Q: Does the i7-13700KF beat the Ultra 5 235A in all multi-threaded tests?

A: No. The i7-13700KF wins Cinebench multi-core and PassMark multithread, but the Ultra 5 235A wins PassMark floating point math (118778 versus 114997) and find prime numbers (392 versus 186).

Q: What explains the 110.8 percent win in find prime numbers?

A: The database records the Ultra 5 235A scoring 392 in PassMark find prime numbers against 186 for the i7-13700KF. The newer chip's larger per-core L1 cache (192 KB versus 80 KB) and L2 cache (3 MB versus 2 MB) likely helps with this recursive workload, though the database does not provide a direct causal explanation.

Q: Is the Ultra 5 235A more power efficient?

A: The recorded TDP is 65 watts for the Ultra 5 235A and 125 watts for the i7-13700KF. The Ultra 5 also uses a 3 nm TSMC process versus 10 nm Intel for the i7-13700KF. The database does not record any measured power consumption figures.

Q: Can either processor be overclocked?

A: Only the i7-13700KF has an unlocked multiplier. The Ultra 5 235A is multiplier locked, so its clock speeds are fixed.

Q: Which processor supports ECC memory?

A: The i7-13700KF supports ECC memory. The Ultra 5 235A does not.

The Verdict

The data points to a clear split by workload type. For rendering, compression, integer math, encryption, and general heavy multi-threading, the Intel Core i7-13700KF is the stronger choice. Its 15.7 percent lead across every Cinebench test and 42.6 percent lead in integer math are decisive. The older chip also offers an unlocked multiplier, ECC memory support, and DDR4 compatibility, which broadens its platform flexibility.

The Intel Core Ultra 5 235A wins the workloads where its architecture appears to excel: prime number calculation, floating point math, and PassMark single-thread. It also carries a significantly lower TDP at 65 watts versus 125 watts, and it includes integrated graphics, which the i7-13700KF lacks. Its 90th percentile standing versus the i7-13700KF's 89th percentile shows the aggregate score is close, but the distribution of wins is not.

Users who prioritize rendering throughput, data compression, or integer-heavy code should choose the i7-13700KF without hesitation. Users who need a lower-power chip with integrated graphics, or who run workloads heavy on prime number calculation and floating point math, should consider the Ultra 5 235A. The i7-13700KF remains the broader performer, winning 13 of 17 recorded comparisons, but the Ultra 5 235A demonstrates that Arrow Lake's efficiency and per-core improvements are real in the right tasks.
