Intel Core 5 223PTE vs Intel Core Ultra 5 245KF Comparison

Head-to-Head Benchmarks

The data shows a decisive advantage for the Intel Core Ultra 5 245KF across every measured workload. The Core Ultra 5 245KF records an average benchmark score of 55093, placing it in the 91st percentile of all CPUs in the database. The Intel Core 5 223PTE, by contrast, has no recorded benchmark scores and sits at the 50th percentile. This gap is not marginal; it is a complete sweep. Benchmark results indicate the Core Ultra 5 245KF delivers superior performance in both single-threaded and multithreaded applications.

Examining the Cinebench results for the Core Ultra 5 245KF provides a clear picture of its capabilities. In Cinebench R23, the multicore score reaches 36647, while the single-core score is 5173. The Cinebench R20 results show a multicore score of 15391 and a single-core score of 2172. The older Cinebench R15 test records a multicore score of 3693 and a single-core score of 521. These numbers indicate strong scaling across core counts and high per-core efficiency. The single-core results, in particular, confirm that the architecture delivers excellent instructions per clock, a critical factor for latency-sensitive tasks.

The Passmark suite reinforces this dominance. The Core Ultra 5 245KF achieves a multithread score of 43110 and a single-thread score of 4715. In specific workloads, the results are equally strong: integer math scores 98854, floating-point math scores 131546, and extended instructions score 37912. Data compression reaches 460123, while data encryption scores 33381. Random string sorting records 55206, and the find prime numbers test scores 416. Physics processing scores 2998. These figures demonstrate balanced performance across diverse computational tasks, from arithmetic throughput to memory-intensive operations.

The nearest rivals for the Core Ultra 5 245KF provide context for its standing. The AMD Ryzen 9 9900X3D records an average score of 54762, which is 0.6% lower than the Core Ultra 5 245KF. The Intel Core 7 253PQE scores 55919, which is 1.5% higher. The Intel Core i9-14900HX scores 56004, which is 1.6% higher. The Intel Core Ultra 5 245K scores 54053, which is 1.9% lower. These deltas show the Core Ultra 5 245KF operating in a tight competitive band, trading blows with high-end desktop and mobile processors, while the Core 5 223PTE has no comparable data to place it in the same conversation.

Architecture Differences

The two processors diverge fundamentally in their underlying design. The Intel Core 5 223PTE uses the Bartlett Lake codename and is built on Intel's 10 nm process node. The Intel Core Ultra 5 245KF uses the Arrow Lake architecture with the Arrow Lake-S codename and is manufactured on a 3 nm process by TSMC. This process difference is significant: the 3 nm node allows for denser transistor packing and improved power efficiency. The Core Ultra 5 245KF contains 17,800 million transistors on a die size of 243 mm², while the Core 5 223PTE has no recorded transistor count or die size in the database.

Core and thread configurations differ substantially. The Core 5 223PTE has 8 cores and 16 threads, indicating hyperthreading support. The Core Ultra 5 245KF has 14 cores and 14 threads, meaning it does not use hyperthreading. Despite having fewer threads, the Core Ultra 5 245KF achieves far higher multithreaded scores, as the benchmark data shows. This suggests that the 14 physical cores on the newer architecture deliver more aggregate throughput than the 8 cores with 16 threads on the older design.

Clock speeds tell a nuanced story. The Core 5 223PTE has a base clock of 2.30 GHz and a boost clock of 5.40 GHz. The Core Ultra 5 245KF has a base clock of 4.20 GHz and a boost clock of 5.20 GHz. The Core 5 223PTE has a higher peak boost, but the Core Ultra 5 245KF has a much higher base clock. The higher base clock on the Core Ultra 5 245KF contributes to sustained performance under load, while the lower base clock on the Core 5 223PTE means it relies heavily on boost behavior to reach competitive speeds.

Cache hierarchies also differ. The Core 5 223PTE 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 5 245KF has 192 KB of L1 cache per core, 3 MB of L2 cache per core, and the same 24 MB of shared L3 cache. The larger per-core L1 and L2 caches on the Core Ultra 5 245KF reduce memory latency and improve data locality, which contributes to its higher single-thread scores.

Memory support and PCIe connectivity reveal additional differences. The Core 5 223PTE supports both DDR4 and DDR5 memory with dual-channel configuration and a memory bandwidth of 89.6 GB/s. The Core Ultra 5 245KF supports only DDR5 memory, also dual-channel, with a higher memory bandwidth of 102.4 GB/s. The Core 5 223PTE supports ECC memory, while the Core Ultra 5 245KF does not. For PCIe, the Core 5 223PTE provides Gen 5 with 16 lanes from the CPU, while the Core Ultra 5 245KF provides Gen 5 with 20 lanes. The extra PCIe lanes on the Core Ultra 5 245KF allow for more expansion devices or additional storage connectivity.

Integrated graphics also differentiate the two. The Core 5 223PTE includes UHD Graphics 770, while the Core Ultra 5 245KF has no integrated graphics, indicated as N/A. This means the Core 5 223PTE can operate without a discrete graphics card, while the Core Ultra 5 245KF requires one. The Core Ultra 5 245KF has an unlocked multiplier, enabling overclocking, while the Core 5 223PTE has a locked multiplier. Socket compatibility differs as well: the Core 5 223PTE uses Intel Socket 1700, while the Core Ultra 5 245KF uses Intel Socket 1851.

The Verdict

The benchmark data is unambiguous. The Intel Core Ultra 5 245KF is the superior processor in every recorded performance category. Its average benchmark score of 55093 places it in the 91st percentile, while the Core 5 223PTE has no recorded scores and sits at the 50th percentile. For users prioritizing raw performance, the Core Ultra 5 245KF is the clear choice. The 14 cores, higher base clock, larger caches, and newer 3 nm process from TSMC all contribute to its dominance.

The Core 5 223PTE, however, serves a different purpose. Its 45 W TDP, compared to the 125 W TDP of the Core Ultra 5 245KF, indicates significantly lower power consumption. The Core 5 223PTE also includes integrated graphics, supports ECC memory, and works with DDR4 memory, making it suitable for systems where reliability, low power, or legacy memory compatibility are priorities. The 16 threads from 8 cores, despite the older architecture, still provide capable multithreaded performance for less demanding workloads.

For a user building a high-performance desktop, the data supports the Core Ultra 5 245KF. Its single-thread score of 4715 and multithread score of 43110 in Passmark, along with Cinebench R23 scores of 5173 single-core and 36647 multicore, demonstrate a level of performance that the Core 5 223PTE cannot approach. The unlocked multiplier on the Core Ultra 5 245KF adds further flexibility for enthusiasts.

For a user building a low-power system, an industrial PC, or a server that requires ECC memory, the Core 5 223PTE is the appropriate selection. The database shows no benchmark records for it, so its absolute performance cannot be quantified here, but its specifications indicate a processor designed for efficiency and stability rather than peak throughput. The integrated UHD Graphics 770 eliminates the need for a separate GPU, and the support for DDR4 memory reduces platform costs.
