Intel Core i5-110 vs Intel Core Ultra 5 250K Plus Comparison

The Verdict

The Intel Core i5-110 and Intel Core Ultra 5 250K Plus occupy completely different tiers of desktop performance. The Core i5-110 is a 6-core, 12-thread Comet Lake part with a 2.90 GHz base and 4.30 GHz boost, while the Core Ultra 5 250K Plus is an 18-core, 18-thread Arrow Lake Refresh chip with a 4.20 GHz base and 5.30 GHz boost. The database records no benchmarks for the Core i5-110, so its average benchmark score is zero and its percentile ranks at 50. In contrast, the Core Ultra 5 250K Plus has a recorded average benchmark score of 66855 and sits in the 93rd percentile of all CPUs.

The Core Ultra 5 250K Plus is the clear choice for anyone running multi-threaded workloads, content creation, or heavy productivity tasks. Its Cinebench R23 multicore score of 30867 and PassMark multithread score of 51596 confirm substantial parallel capability. The Core i5-110, with no recorded benchmark data, cannot be validated for any performance claim. Users needing a proven desktop processor should select the Core Ultra 5 250K Plus. The Core i5-110 is only relevant for legacy Socket 1200 platforms where the 65 W TDP and DDR4 memory support fit an existing build.

Architecture Differences

The two processors are built on fundamentally different silicon. The Core i5-110 uses Intel's 14 nm process node and Comet Lake architecture, produced at Intel's own foundry. The Core Ultra 5 250K Plus uses a 3 nm process node manufactured by TSMC, with the Arrow Lake Refresh codename. This process shrink delivers significant efficiency and density advantages for the newer part.

Core counts differ sharply. The Core i5-110 has 6 cores and 12 threads, indicating Hyper-Threading support. The Core Ultra 5 250K Plus has 18 cores and 18 threads, meaning no simultaneous multithreading, but the raw core count is triple. The transistor count for the Core Ultra 5 250K Plus is 17,800 million on a 243 mm² die. The Core i5-110 has no recorded transistor or die size data.

Cache hierarchies are also different. The Core i5-110 provides 64 KB L1 and 256 KB L2 per core, with 12 MB shared L3. The Core Ultra 5 250K Plus offers 192 KB L1 and 3 MB L2 per core, plus 30 MB shared L3. The newer chip's per-core L2 is more than ten times larger, which helps with data locality and reduces memory traffic.

Memory and I/O capabilities differ as well. The Core i5-110 supports DDR4 with dual-channel memory and 42.7 GB/s bandwidth, and it lacks ECC memory support. The Core Ultra 5 250K Plus supports DDR5, also dual-channel, but with 115.2 GB/s bandwidth, nearly triple the bandwidth. It also supports ECC memory. PCIe connectivity is another split: the Core i5-110 uses Gen 3 with 16 CPU lanes, while the Core Ultra 5 250K Plus uses Gen 5 with 20 CPU lanes.

Integrated graphics differ, with the Core i5-110 featuring UHD Graphics 630 and the Core Ultra 5 250K Plus using Arc Xe-LPG Graphics 64EU. The Core Ultra 5 250K Plus has an unlocked multiplier, while the Core i5-110 is locked. Sockets are incompatible: Socket 1200 for the older chip, Socket 1851 for the newer one.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark comparisons between these two CPUs. The Core i5-110 has no recorded benchmark entries at all, so no direct score deltas can be calculated. The Core Ultra 5 250K Plus, however, has a full benchmark suite recorded. Its Cinebench R15 multicore score is 4640, with a single-core score of 328. In Cinebench R20, the multicore score reaches 18442 and single-core 2603. Cinebench R23 results show a multicore score of 30867 and single-core 2261.

PassMark results for the Core Ultra 5 250K Plus cover multiple workloads. Data compression scores 568721, data encryption 42144, and extended instructions 44565. Prime number finding scores 486, floating point math 162692, integer math 125091, and multithread 51596. Physics scores 3494, random string sorting 69090, and single thread 4757.

Without any benchmark data for the Core i5-110, the database cannot establish a performance delta between the two. The Core Ultra 5 250K Plus stands as the only one with measurable performance. Its nearest rivals in the database provide context: the AMD EPYC 4465P scores 66925, a 0.1 percent advantage, and the Intel Xeon 6515P scores 67006, a 0.2 percent edge. The Intel Core Ultra 9 275HX scores 67469, 0.9 percent higher. The Core Ultra 5 250KF Plus, a sibling without integrated graphics, scores 66159, which the 250K Plus beats by 1.1 percent.

Where Each One Wins

The Core Ultra 5 250K Plus wins on every measurable performance axis in the database. Its recorded benchmarks cover Cinebench R15, R20, and R23, plus a full PassMark suite. The 18-core configuration with 30 MB L3 cache and 3 nm process node positions it for heavy multi-threaded work. The 115.2 GB/s DDR5 bandwidth supports memory-intensive applications. The Gen 5 PCIe with 20 lanes enables newer expansion cards. The Arc Xe-LPG Graphics 64EU integrated GPU is more capable than the older UHD Graphics 630. The unlocked multiplier allows tuning. The 93rd percentile standing among all CPUs confirms its high placement.

The Core i5-110 has no recorded benchmark scores, so it cannot claim any measured wins. Its advantages are structural. The 65 W TDP means lower power draw. The DDR4 support aligns with older, widely available memory. The Socket 1200 compatibility suits existing Comet Lake motherboards. The 42.7 GB/s bandwidth is sufficient for lighter workloads. The 12 MB L3 cache and 6 cores handle basic desktop tasks. The 50th percentile ranking places it in the middle of the database's CPU distribution, but without benchmark scores, that ranking is not backed by measured data.

For users choosing between the two, the Core Ultra 5 250K Plus is the only option with verified performance. The Core i5-110 is a legacy part for platform-specific builds where low TDP and DDR4 are requirements. The Core Ultra 5 250K Plus delivers roughly triple the core count, more than double the L3 cache, and nearly triple the memory bandwidth, all on a 3 nm process.
