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

The Intel Core 5 213PE and Intel Core Ultra 7 265T are both current desktop processors from Intel, but they target different segments of the market. The 213PE is part of the Bartlett Lake generation, built for the established LGA1700 platform, while the 265T is a Core Ultra Series 2 part based on Arrow Lake for the newer LGA1851 socket. The benchmark data shows a clear performance hierarchy, but the choice between them depends on specific workload priorities and platform requirements.

Head-to-Head Benchmarks

The head-to-head results are one-sided. The Intel Core Ultra 7 265T wins every single one of the 17 recorded benchmark comparisons. The most lopsided victory comes in the PassMark find prime numbers test, where the 265T scores 322 against the 213PE's 114, a 64.6% advantage. This indicates a massive difference in integer-heavy, branch-predictor-intensive workloads.

The Cinebench suite shows a consistent pattern. In Cinebench R23 multi-core, the 265T scores 31,558 versus 22,468 for the 213PE, a 28.8% lead. The single-core test in R23 shows a smaller but still significant gap: 4,455 versus 3,172, also a 28.8% difference. This consistency across Cinebench R15, R20, and R23 suggests the 265T's architectural advantages translate uniformly across rendering workloads, both single-threaded and multi-threaded.

The floating-point math test reveals another major divide. The 265T scores 129,817 compared to 68,587 for the 213PE, a 47.2% lead. This is one of the largest deltas outside of the prime number test and highlights the 265T's superior FPU throughput. Data encryption also shows a substantial gap: 29,687 versus 15,916, a 46.4% difference. The 265T's newer architecture handles cryptographic instructions much more efficiently.

The smallest margin is in the PassMark single-thread test. The 265T scores 4,338 versus 4,060, a 6.4% lead. This is the closest result in the entire comparison and shows that for purely single-threaded, non-rendering tasks, the 213PE's high boost clock keeps it competitive. The integer math test is the second closest, with the 265T at 104,943 versus 92,089, a 12.2% lead.

The multithread score follows the broader trend. The 265T posts 37,084 versus 26,434, a 28.7% lead. Data compression shows a 19.3% advantage for the 265T (370,158 versus 298,804), while random string sorting favors the 265T by 27.9% (44,400 versus 32,027). Extended instructions show a 31.6% lead for the 265T (28,609 versus 19,565), and physics simulation shows a 32.1% lead (2,391 versus 1,624).

Where Each One Wins

The data indicates the Intel Core Ultra 7 265T is the outright winner in every measured category. There are no benchmark tests where the Core 5 213PE comes out ahead. For users running Cinebench rendering, PassMark physics simulations, or any floating-point-heavy application, the 265T delivers between 28% and 47% more performance.

The 213PE's closest performance point is in single-threaded PassMark tests, where the gap narrows to 6.4%. This suggests that for legacy applications that rely heavily on single-core speed without using modern instruction sets, the two processors are much closer in feel. However, the 265T still wins that test.

The 265T's dominance in data encryption and prime number finding indicates it is better suited for security-related workloads, cryptography, and mathematical computing. The 213PE, while slower in absolute terms, still posts respectable scores in integer math and data compression, making it a functional choice for general productivity that does not demand maximum throughput.

Architecture Differences

The two processors come from different generations and use fundamentally different designs. The Core 5 213PE is built on the Bartlett Lake architecture using a 10 nm process at Intel's own foundries. It uses an Intel Socket 1700 platform. The Core Ultra 7 265T is based on Arrow Lake, specifically the Arrow Lake-S variant, fabricated on a 3 nm process by TSMC. It uses the newer Intel Socket 1851.

Core configuration differs substantially. The 213PE has 8 cores and 16 threads, while the 265T has 20 cores and 20 threads. The 265T does not use simultaneous multithreading, which explains its thread count matching its core count. The 213PE relies on Hyper-Threading to reach 16 threads from 8 cores.

Clock speeds favor the 213PE in base frequency but the 265T in boost. The 213PE has a base clock of 2.70 GHz and a boost clock of 5.20 GHz. The 265T has a lower base clock of 1.50 GHz but a marginally higher boost of 5.30 GHz. The 265T's lower base clock is offset by its vastly higher core count.

Cache hierarchies differ in both size and organization. The 213PE has 80 KB of L1 cache per core, 2 MB of L2 per core, and 24 MB of shared L3 cache. The 265T has 192 KB of L1 per core, 3 MB of L2 per core, and 30 MB of shared L3. The 265T also has a much larger transistor count at 17,800 million versus an unlisted figure for the 213PE, and a die size of 243 mm².

Memory support is another key split. The 213PE supports both DDR4 and DDR5, while the 265T supports only DDR5. Both use dual-channel memory buses, but the 265T has a higher memory bandwidth at 102.4 GB/s versus 76.8 GB/s for the 213PE. The 213PE supports ECC memory, which the 265T does not.

PCIe capabilities also differ. The 213PE provides 16 PCIe Gen 5 lanes from the CPU, while the 265T provides 20 Gen 5 lanes. Integrated graphics differ as well: the 213PE uses UHD Graphics 730, while the 265T uses Arc Xe-LPG Graphics with 64 execution units.

The Verdict

The benchmark data is unambiguous. The Intel Core Ultra 7 265T delivers superior performance in every recorded test, with margins ranging from 6.4% in single-threaded PassMark to 64.6% in prime number finding. Its 20-core configuration, larger caches, and newer 3 nm process give it a decisive edge in multi-threaded rendering, encryption, and floating-point workloads.

The Core 5 213PE remains relevant for specific use cases. Its support for DDR4 memory and ECC functionality makes it a candidate for systems that require those features. Its 65-watt TDP is higher than the 265T's 35-watt rating, but it uses the older LGA1700 platform, which may be more accessible or preferred for builds with existing motherboards.

For users who prioritize raw performance across all workload types, the Core Ultra 7 265T is the clear choice. Its 90th percentile ranking among all CPUs, compared to the 85th percentile for the 213PE, confirms its higher standing. The 265T also sits near the AMD Ryzen 9 7900X3D in average benchmark score, with a 0.4% difference, showing it competes at a high level. The 213PE, by contrast, is closely matched with the Intel Core i7-12700K, trailing by only 0.4% in average score.

The decision comes down to platform needs and workload demands. The 265T is faster, cooler, and more efficient. The 213PE offers legacy memory support and ECC. For pure performance, the data points to the 265T without qualification.
