Intel Core 5 213PE vs Intel Core Ultra 7 265K Comparison

Intel Core 5 213PE and Intel Core Ultra 7 265K occupy different tiers in the desktop processor stack, and the benchmark data reflects that positioning clearly. The Core Ultra 7 265K dominates the overwhelming majority of recorded tests, while the Core 5 213PE secures a single, though notable, victory in one Cinebench workload. The following analysis breaks down the recorded performance differences, architectural splits, and specification gaps between these two Intel desktop parts.

Head-to-Head Benchmarks

The Core Ultra 7 265K wins 16 of the 17 head-to-head benchmark comparisons recorded in the database. The largest margin appears in the Passmark find prime numbers test, where the Core Ultra 7 265K scores 491 against 114 for the Core 5 213PE, a delta of 76.8 percent. This is a workload that scales heavily with core count and memory bandwidth, and the data shows a decisive advantage for the higher-tier part.

Passmark data encryption shows a 67 percent gap, with the Core Ultra 7 265K scoring 48246 compared to 15916 for the Core 5 213PE. Extended instructions follow at 64 percent ahead, with scores of 54333 and 19565 respectively. Floating point math results indicate a 63.8 percent lead for the Core Ultra 7 265K, recording 189629 versus 68587.

The Cinebench R15, R20, and R23 multicore tests all favor the Core Ultra 7 265K, but the margins differ. In Cinebench R15 multicore, the Core Ultra 7 265K scores 5020 against 2264, a 54.9 percent advantage. The R20 multicore test shows the same 54.9 percent delta, with scores of 20918 and 9436. However, the R23 multicore gap narrows to 37.3 percent, with the Core Ultra 7 265K at 35850 and the Core 5 213PE at 22468. This suggests that the R23 workload does not scale as perfectly with the Core Ultra 7 265K's additional resources as the older Cinebench versions do.

The single-core picture is mostly one-sided, but with one important exception. Cinebench R15 single-core gives the Core Ultra 7 265K a 54.9 percent lead, scoring 708 versus 319. Cinebench R20 single-core follows the same pattern, with 2953 against 1332, again a 54.9 percent delta. Passmark single-thread shows a smaller but still clear 17.6 percent advantage for the Core Ultra 7 265K, scoring 4928 versus 4060.

The exception is Cinebench R23 single-core, where the Core 5 213PE wins with a score of 3172 against 2020 for the Core Ultra 7 265K. This is a 57 percent delta in favor of the Core 5 213PE, and it is the only benchmark in the entire head-to-head set where the lower-tier processor comes out ahead. The result stands out because the Core Ultra 7 265K wins every other single-threaded test by a wide margin. The recorded data does not explain the cause, but the R23 single-core result is consistent and cannot be dismissed as noise.

Passmark multithread shows a 54.9 percent lead for the Core Ultra 7 265K, with scores of 58594 and 26434. Physics follows at 56.5 percent, with 3731 against 1624. Random string sorting shows a 59.8 percent gap, with 79752 versus 32027. Data compression is close to the largest margin at 55.1 percent, with 665554 against 298804. Integer math shows a comparatively modest 35.7 percent lead, with 143242 versus 92089.

The average benchmark score in the database tells the same story. The Core Ultra 7 265K averages 70879 across all recorded benchmarks, while the Core 5 213PE averages 35428. The percentile ranking places the Core Ultra 7 265K at the 94th percentile of all CPUs, while the Core 5 213PE sits at the 85th percentile.

Where Each One Wins

The Core Ultra 7 265K wins in every category except one. Multithreaded rendering, data compression, encryption, extended instruction workloads, prime number finding, floating point math, integer math, physics simulation, and random string sorting all record substantial leads for the Core Ultra 7 265K. The margins range from 35.7 percent in integer math to 76.8 percent in prime number finding. The Core Ultra 7 265K also wins the Cinebench R15 and R20 single-core tests, along with the Passmark single-thread test, so its single-thread advantage is not limited to older workloads.

The Core 5 213PE wins exactly one recorded test: Cinebench R23 single-core. The score of 3172 surpasses the Core Ultra 7 265K's 2020 by 57 percent. This is an unusual result given the Core Ultra 7 265K's higher boost clock and newer process node, but the database records it as a clean win for the Core 5 213PE. No other benchmark in the set favors the Core 5 213PE.

For workloads that resemble Cinebench R23 single-core, the Core 5 213PE may hold an advantage. For everything else, the data points to the Core Ultra 7 265K as the stronger part. The Passmark single-thread score of 4060 for the Core 5 213PE versus 4928 for the Core Ultra 7 265K suggests that the R23 single-core result is an outlier rather than a general trend, but it remains the only head-to-head win for the Core 5 213PE across all recorded tests.

Architecture Differences

The two processors come from different Intel generations and use different manufacturing approaches. The Core 5 213PE uses the Bartlett Lake codename and is built on a 10 nm process node at Intel's own foundry. The Core Ultra 7 265K uses the Arrow Lake-S codename, belongs to the Core Ultra Series 2, and is built on a 3 nm process node at TSMC. The Core Ultra 7 265K lists 17,800 million transistors and a die size of 243 mm², while the Core 5 213PE does not have recorded transistor or die size data.

Core counts differ substantially. The Core 5 213PE has 8 cores and 16 threads, while the Core Ultra 7 265K has 20 cores and 20 threads. The Core 5 213PE uses simultaneous multithreading to reach 16 threads from 8 cores, while the Core Ultra 7 265K has no thread multiplier and runs one thread per core. Despite having 20 threads to the Core Ultra 7 265K's 20, the Core 5 213PE's 8 physical cores limit its multithreaded throughput compared to the 20 physical cores of the Core Ultra 7 265K.

Cache hierarchies also differ. The Core 5 213PE has 80 KB of L1 cache per core, 2 MB of L2 cache per core, and 24 MB of shared L3 cache. The Core Ultra 7 265K has 192 KB of L1 cache per core, 3 MB of L2 cache per core, and 30 MB of shared L3 cache. The larger per-core caches and the larger shared L3 cache on the Core Ultra 7 265K align with its higher core count and newer architecture.

Clock speeds favor the Core Ultra 7 265K in base frequency but not in boost frequency. The Core 5 213PE has a base clock of 2.70 GHz and a boost clock of 5.20 GHz. The Core Ultra 7 265K has a base clock of 3.90 GHz and a boost clock of 5.50 GHz. The Core Ultra 7 265K boosts 0.30 GHz higher, but the Core 5 213PE's Cinebench R23 single-core win suggests that raw boost clock does not tell the full story.

Memory support differs as well. The Core 5 213PE supports both DDR4 and DDR5 memory, while the Core Ultra 7 265K supports only DDR5. Both use a dual-channel memory bus. The Core Ultra 7 265K records a memory bandwidth of 102.4 GB/s, while the Core 5 213PE records 76.8 GB/s. Both support ECC memory.

The integrated graphics units are different. The Core 5 213PE uses UHD Graphics 730, while the Core Ultra 7 265K uses Arc Xe-LPG Graphics 64EU. PCIe support also differs: the Core 5 213PE provides Gen 5 with 16 lanes from the CPU, while the Core Ultra 7 265K provides Gen 5 with 20 lanes.

The sockets are incompatible. The Core 5 213PE uses Intel Socket 1700, while the Core Ultra 7 265K uses Intel Socket 1851. The multiplier is locked on the Core 5 213PE and unlocked on the Core Ultra 7 265K. The release dates are also different: the Core Ultra 7 265K was released on 2024-10-23, while the Core 5 213PE was released on 2026-03-08.

The Verdict

The recorded data shows a clear performance hierarchy. The Core Ultra 7 265K wins 16 of 17 head-to-head benchmarks, often by margins exceeding 50 percent. Its average benchmark score of 70879 is roughly double the Core 5 213PE's 35428, and its 94th percentile ranking versus the 85th percentile for the Core 5 213PE confirms the gap. The Core Ultra 7 265K also carries a higher TDP of 125 watts compared to 65 watts, which aligns with its larger core count and higher base clock.

The Core 5 213PE has one meaningful advantage in the data: the Cinebench R23 single-core score of 3172 versus 2020, a 57 percent lead. This result is isolated, and all other single-threaded tests favor the Core Ultra 7 265K. The Core 5 213PE also supports DDR4 memory, which may matter for users with existing DDR4 systems, and it uses the older Socket 1700 platform. The Core Ultra 7 265K requires DDR5 and Socket 1851.

Users building a new system with maximum multithreaded performance should look at the Core Ultra 7 265K based on the benchmark record. Users with a specific workload that resembles Cinebench R23 single-core, or those who want to reuse DDR4 memory on a Socket 1700 platform, may find the Core 5 213PE sufficient. The data does not support a general recommendation for the Core 5 213PE beyond its single recorded win and its lower TDP.
