Intel Core 5 223PE vs Intel Core Ultra 7 268V Comparison

The Intel Core 5 223PE and Intel Core Ultra 7 268V are both 8-core Intel processors, but they are engineered for completely different segments. The Core 5 223PE is a desktop part with a 65 TDP, while the Core Ultra 7 268V is a 17-watt mobile processor. The benchmark data shows a dominant performance gap in favor of the desktop chip, but the mobile part has its own niche where it excels.

Where Each One Wins

The data shows a clear split: the Intel Core 5 223PE wins 16 of the 17 recorded head-to-head benchmarks. The only test it loses is PassMark's find prime numbers, where the Core Ultra 7 268V scores 192 against 159, a 17.2% advantage. This single win is notable because it suggests the Lunar Lake architecture has a specific strength in this particular workload, likely due to its newer instruction handling or memory subsystem.

Every Cinebench test, both single-core and multi-core, goes to the Core 5 223PE. The multi-core deltas are massive, ranging from 65% in R15 to 148.3% in R23. The desktop chip also dominates PassMark's integer math, floating point math, data compression, encryption, extended instructions, multithread, physics, and random string sorting tests. The smallest win for the desktop part is in PassMark's single-thread test, where it leads by only 4.1% (4219 vs 4051), indicating that for lightly threaded tasks, the two processors are far closer in capability.

Architecture Differences

The two processors use fundamentally different silicon. The Core 5 223PE is built on Intel's 10 nm process and uses the Bartlett Lake codename, a desktop architecture. The Core Ultra 7 268V belongs to the Core Ultra Series 2, uses the Lunar Lake architecture, and is manufactured on TSMC's 3 nm node. This process difference explains the massive TDP disparity: the desktop chip is rated at 65 watts, while the mobile chip is rated at just 17 watts.

Cache configurations also differ significantly. The Core 5 223PE has 80 KB of L1 cache per core, 2 MB of L2 per core, and 24 MB of shared L3 cache. The Core Ultra 7 268V has 192 KB of L1 per core, 2.5 MB of L2 per core, but only 12 MB of shared L3. The desktop part has double the L3 capacity, which helps in multi-threaded and data-heavy workloads. Thread counts differ as well: the Core 5 223PE supports 16 threads across its 8 cores, while the Core Ultra 7 268V has 8 threads, meaning it lacks simultaneous multithreading.

Memory support is another divider. The Core 5 223PE supports DDR4 and DDR5 memory in a dual-channel configuration with 89.6 GB/s of bandwidth. The Core Ultra 7 268V also uses dual-channel memory, but its specific memory types depend on the motherboard, and the database does not record a bandwidth figure for it. The desktop chip also supports ECC memory, which the mobile chip does not. PCIe lanes differ sharply: the Core 5 223PE provides 16 Gen 5 lanes from the CPU, while the Core Ultra 7 268V provides only 4 Gen 5 lanes, reflecting its mobile, power-constrained design.

Integrated graphics also separate the two. The Core 5 223PE uses UHD Graphics 730, while the Core Ultra 7 268V uses Arc 140V. The database does not provide graphics benchmarks, but the Arc 140V is associated with the Lunar Lake platform's focus on integrated graphics performance. The sockets are incompatible: the desktop chip uses Intel Socket 1700, while the mobile chip uses Intel BGA 2833.

The Verdict

The data is unambiguous. The Intel Core 5 223PE is the faster processor in nearly every recorded workload. Its average benchmark score is 40585, placing it in the 87th percentile of all CPUs, while the Core Ultra 7 268V averages 20897 and sits in the 74th percentile. The desktop chip's nearest rivals include the Intel Core 7 253PE (0.1% behind) and the AMD Ryzen AI 5 PRO 435G (0.3% ahead), showing it competes in a higher performance tier. The Core Ultra 7 268V's nearest rivals are the AMD Ryzen 5 PRO 4655GE and the Intel Core i5-12600T, both within 0.1% of its average score.

For desktop users building a system where power draw is not the primary constraint, the Core 5 223PE is the clear choice. It delivers superior multi-core rendering, mathematical throughput, and data processing. For mobile users who need a processor that fits a 17-watt envelope, the Core Ultra 7 268V is the only viable option in this comparison, and it holds a specific advantage in prime number finding. The 4.1% single-thread gap also means that for everyday responsiveness, the mobile chip is not dramatically behind. The Core 5 223PE has a launch MSRP of $232, but no such figure is recorded for the Core Ultra 7 268V.
