Intel Core 5 223PE vs Intel Core 5 315 Comparison

The Intel Core 5 223PE and Intel Core 5 315 are two very different processors that share a name but target opposite ends of the computing spectrum. The 223PE is a desktop part built for sustained throughput, while the 315 is a low-power mobile chip designed for efficiency. The benchmark data confirms a complete sweep: the 223PE wins all 17 recorded head-to-head tests. However, the margin of victory varies wildly depending on the workload, revealing that these chips are not just different in speed, but fundamentally different in design philosophy. The 223PE achieves a 104% lead in Cinebench multi-core tests, yet only a 4.9% lead in PassMark single-thread performance, indicating that the 315 is far more competitive in lightly-threaded tasks than its overall score suggests.

Where Each One Wins

The Intel Core 5 223PE wins every single benchmark in the database. There is no test where the Core 5 315 manages to take the lead. The most decisive victory for the 223PE comes in PassMark integer math, where it scores 99,819 against 31,690, a 215% advantage. This extreme gap suggests that the 223PE’s 8 cores and 16 threads are heavily favored by integer-heavy workloads. The Cinebench R23 multi-core test shows a similar story, with the 223PE scoring 26,455 versus 12,981, a 103.8% improvement. The 223PE also excels in data compression, scoring 346,623 against 146,143, a 137.2% lead, which makes it the clear choice for archiving and file management tasks.

The Core 5 315 does not win any benchmarks, but its closest performance comes in the PassMark single-thread tests. The 315 scores 4,021 against the 223PE’s 4,219, a deficit of only 4.9%. This narrow gap shows that for basic single-threaded interactions, such as opening applications or navigating a browser, the 315 is nearly as responsive as its much larger desktop sibling. The 315 also performs relatively well in extended instructions, scoring 13,143 against 24,672, a 87.7% gap, which is smaller than the gaps seen in integer math or compression. The 315’s performance profile suggests it is best suited for mobile workflows that require short bursts of speed with minimal power draw, while the 223PE is built for long-duration, multi-threaded workloads.

Architecture Differences

The two processors come from entirely different manufacturing processes and design families. The Core 5 223PE is based on the Bartlett Lake architecture and is built on a 10 nm process node. It uses the Intel Socket 1700 platform, which is a standard desktop interface. The Core 5 315, in contrast, uses the Wildcat Lake architecture and is manufactured on a 3 nm process node. This node advantage allows the 315 to achieve its low 15 W TDP, compared to the 223PE’s 65 W TDP. The 315 is also a mobile part, using the Intel BGA 1516 socket, which means it is soldered directly to the motherboard rather than being user-upgradeable.

The core configurations differ dramatically. The 223PE has 8 cores and 16 threads, meaning it supports simultaneous multithreading, while the 315 has 6 cores and 6 threads, with no hyper-threading support. The 223PE’s base clock is 2.90 GHz with a boost clock of 5.20 GHz, whereas the 315 runs at a much lower 1.50 GHz base and 4.40 GHz boost. The cache hierarchy also reflects their different roles. The 223PE uses an 80 KB per core L1 cache, a 2 MB per core L2 cache, and a 24 MB shared L3 cache. The 315 uses a single 192 KB L1, a 2.5 MB L2, and a much smaller 6 MB shared L3 cache. The 223PE supports DDR4 and DDR5 memory over a dual-channel bus with 89.6 GB/s bandwidth, while the 315 only supports DDR5 and LPDDR5X over a single-channel bus with 59.7 GB/s bandwidth. The 223PE also supports ECC memory, which the 315 does not.

The PCIe capabilities are also split by platform. The 223PE provides Gen 5 connectivity with 16 lanes, while the 315 is limited to Gen 4 with just 6 lanes. Integrated graphics differ as well: the 223PE uses UHD Graphics 730, while the 315 uses Intel Xe3 Graphics with 2 Xe cores. The 315’s graphics are part of its mobile design, where it can handle modern display output with lower power consumption. Both processors have locked multipliers, so neither supports overclocking. The 223PE was released on 2026-03-08, while the 315 followed on 2026-04-15. The 223PE carries a launch MSRP of $232, while the 315 has a launch MSRP of $340.
