Intel Core i7-13700KF vs Intel Core Ultra 5 245 Comparison

Head-to-Head Benchmarks

The benchmark results show a clear split between these two processors. The Intel Core i7-13700KF wins 13 of the 17 recorded head-to-head tests, while the Intel Core Ultra 5 245 takes 4 wins. The margin of victory matters more than the raw count.

In Cinebench testing, the i7-13700KF is consistently ahead. Across all six Cinebench tests (R15, R20, and R23, each in multicore and singlecore variants), the i7-13700KF leads by a uniform 14.9%. That consistency suggests a fundamental throughput advantage rather than a workload-specific quirk. The R23 multicore score of 38,704 for the i7-13700KF versus 32,924 for the Core Ultra 5 245 is a substantial gap for heavily threaded rendering tasks.

The PassMark suite shows where each chip excels. The i7-13700KF dominates integer math with a score of 154,507, which is 41% ahead of the Core Ultra 5 245's 91,187. Data compression also heavily favors the i7-13700KF: 596,493 versus 400,942, a 32.8% difference. Random string sorting goes to the i7-13700KF by 21.7% (62,726 versus 49,140). Multithreaded performance in PassMark favors the i7-13700KF by 15.5% (45,817 versus 38,706).

The Core Ultra 5 245 shows its strengths in specific areas. The most dramatic win is in PassMark's find prime numbers test, where it scores 365 versus 186, a 96.2% advantage. That test often reflects efficiency in certain instruction patterns, and the Arrow Lake architecture clearly handles it better. Floating point math also goes to the Core Ultra 5 245 by a modest 4.8% (120,548 versus 114,997). In single-threaded PassMark tests, the Core Ultra 5 245 edges out the i7-13700KF by 1.3% (4,394 versus 4,336).

Data encryption and extended instructions tests show closer margins. The i7-13700KF leads data encryption by 9.2% (33,314 versus 30,236) and extended instructions by 9.3% (36,700 versus 33,304). Physics testing is nearly a tie, with the i7-13700KF ahead by only 3.1% (2,650 versus 2,569).

Overall average benchmark scores place the Core Ultra 5 245 at 48,995, which is 3.5% higher than the i7-13700KF's 47,330. The Core Ultra 5 245 sits at the 90th percentile of all CPUs, while the i7-13700KF sits at the 89th. These aggregate numbers tell a different story than the head-to-head wins, because the Core Ultra 5 245's massive prime number advantage and its single-thread win help balance the i7-13700KF's broader victories.

The Verdict

The data points to a simple conclusion: pick the i7-13700KF for most productivity and content creation workloads, and pick the Core Ultra 5 245 if your work specifically involves prime number calculations, floating point math, or you want the slight single-thread edge in PassMark.

The i7-13700KF's 14.9% lead across every Cinebench test makes it the default choice for rendering, video encoding, and any task that scales across cores. Its 41% lead in integer math and 32.8% lead in data compression reinforce that position for general computing and file-handling workloads.

The Core Ultra 5 245 is not a weak chip. Its 90th percentile ranking, its near-doubling of the i7-13700KF in prime number finding, and its win in floating point math show that Arrow Lake brings real efficiency gains in specific math-heavy tasks. The 1.3% single-thread PassMark victory also matters for lightly threaded responsiveness.

Consider the socket situation. The Core Ultra 5 245 uses Intel Socket 1851, while the i7-13700KF uses Intel Socket 1700. These are not interchangeable. Your motherboard choice locks you into one platform, and the benchmark data should inform that decision based on your primary workloads.

Where Each One Wins

The i7-13700KF wins in rendering and multithreaded applications. Cinebench R23 multicore at 38,704 versus 32,924 means faster video exports and 3D scene renders. Data compression at 596,493 versus 400,942 helps with archiving, backup tools, and file transfer utilities. Integer math at 154,507 versus 91,187 benefits spreadsheet calculations, database operations, and many business applications.

The i7-13700KF also wins in encryption tasks (33,314 versus 30,236), extended instruction workloads (36,700 versus 33,304), random string sorting (62,726 versus 49,140), and general multithreaded PassMark performance (45,817 versus 38,706). If your workflow involves any of these, the i7-13700KF is the stronger performer.

The Core Ultra 5 245 wins decisively in prime number finding (365 versus 186), which matters for cryptography research, some scientific computing, and mathematical software. Floating point math (120,548 versus 114,997) benefits scientific simulations, physics engines, and financial modeling. The single-thread PassMark win (4,394 versus 4,336) gives the Core Ultra 5 245 a slight edge in applications that rely heavily on one core.

For gaming, the data is mixed. The Core Ultra 5 245 has the single-thread edge in PassMark, but the i7-13700KF wins the single-core Cinebench tests by 14.9%. The i7-13700KF's higher boost clock of 5.40 GHz versus 5.10 GHz likely explains that difference, though the Core Ultra 5 245's better single-thread PassMark score complicates the picture. Game performance depends on which benchmark better represents your target games.

Architecture Differences

The Core Ultra 5 245 is built on Arrow Lake architecture with a 3 nm process node from TSMC. It uses 17,800 million transistors on a 243 mm² die. The i7-13700KF uses Raptor Lake architecture on Intel's 10 nm process, with a 257 mm² die size and no transistor count listed in the database.

The Core Ultra 5 245 features an integrated graphics solution: Arc Xe-LPG Graphics with 64 execution units. The i7-13700KF has no integrated graphics, which explains the "F" suffix in its name. This means the i7-13700KF requires a discrete GPU for any display output, while the Core Ultra 5 245 can run headless or with a basic display setup.

Memory architecture differs significantly. The Core Ultra 5 245's memory bandwidth is listed at 102.4 GB/s with DDR5 support only. The i7-13700KF supports both DDR4 and DDR5, though its memory bandwidth is not recorded in the database. For new builds, the Core Ultra 5 245's DDR5-only support means you must buy DDR5 memory. The i7-13700KF gives you the option to reuse DDR4 modules from an older system.

Cache layouts differ between the two. The Core Ultra 5 245 has 192 KB of L1 cache per core, 3 MB of L2 cache per core, and 24 MB of shared L3 cache. The i7-13700KF has 80 KB of L1 cache per core, 2 MB of L2 cache per core, and 30 MB of shared L3 cache. The i7-13700KF's larger L3 cache may help in some workloads, while the Core Ultra 5 245's larger per-core L1 and L2 caches could benefit latency-sensitive tasks.

The Core Ultra 5 245 has a locked multiplier, while the i7-13700KF has an unlocked multiplier. This means the i7-13700KF can be overclocked, while the Core Ultra 5 245 cannot. For enthusiasts who plan to push clock speeds, the i7-13700KF is the only option here.

Specification Differences

The core and thread counts are the first major difference. The i7-13700KF has 16 cores and 24 threads, compared to 14 cores and 14 threads for the Core Ultra 5 245. The i7-13700KF's Hyper-Threading support gives it 8 additional threads over its core count, while the Core Ultra 5 245 has a 1:1 core-to-thread ratio.

Clock speeds favor the i7-13700KF in boost, but the Core Ultra 5 245 has a higher base clock. The i7-13700KF boosts to 5.40 GHz with a 3.40 GHz base. The Core Ultra 5 245 boosts to 5.10 GHz with a 3.50 GHz base. The i7-13700KF's 300 MHz higher boost clock likely contributes to its Cinebench single-core wins.

Power consumption differs substantially. The i7-13700KF has a TDP of 125 watts, while the Core Ultra 5 245 has a TDP of 65 watts. This means the Core Ultra 5 245 should be easier to cool and may fit in smaller systems, though the i7-13700KF's higher power budget allows for more sustained performance in multithreaded workloads.

Both processors support ECC memory, PCIe Gen 5 with 20 CPU lanes, and dual-channel memory. The launch MSRP for the Core Ultra 5 245 is $270, and the launch MSRP for the i7-13700KF is $384. The release dates differ: the i7-13700KF launched in 2022, while the Core Ultra 5 245 launched in 2025.

The Core Ultra 5 245 has part number SRVFE, and the i7-13700KF has part number SRMB9. Both are listed as Active in production status and target the Desktop market segment.
