Intel Core i3-14100T vs Intel Core Ultra 5 225T Comparison

The Intel Core i3-14100T and the Intel Core Ultra 5 225T are two very different desktop processors, separated by a generation gap. The data in the database shows that the Core Ultra 5 225T wins all 17 head-to-head benchmark comparisons, establishing a clear performance hierarchy. However, the nature of those wins, the architectural changes, and the platform requirements tell a more nuanced story about what each chip is designed to do.

Where Each One Wins

The performance split between these two chips is not subtle. The Core i3-14100T is a low-power, 35-watt processor built for efficiency and basic computing tasks. Its 4 cores and 8 threads are sufficient for everyday workloads like web browsing, office productivity, and light media consumption. The data shows it sits at the 71st percentile of all CPUs in the database, which is respectable for a chip of its class. In practical terms, it delivers smooth performance for single-threaded applications and modest multi-tasking, but its Passmark multi-thread score of 13662 and Cinebench R23 multi-core score of 11612 indicate its limits under heavy parallel loads.

The Core Ultra 5 225T, on the other hand, is a 65-watt processor that occupies a completely different performance tier. With 10 cores and 10 threads, it is designed for more demanding workloads. The benchmark data confirms this: its Passmark multi-thread score of 25358 is 46.1% higher than the i3-14100T, and its Cinebench R23 multi-core score of 21971 is 47.1% higher. This places the Core Ultra 5 225T at the 82nd percentile of all CPUs, a significant jump from the i3's 71st percentile. The Ultra 5 is the clear winner for content creation, software compilation, and any workload that scales with core count.

Single-threaded performance also favors the Core Ultra 5 225T, though by a smaller margin. Its Passmark single-thread score of 4348 is 19.5% higher than the i3-14100T's 3498. This translates to faster response times in everyday applications and better performance in lightly threaded games. The i3-14100T is not a gaming-focused chip, but the Ultra 5's higher boost clock and newer architecture give it a meaningful edge even in scenarios that rely on a single core.

The only area where the i3-14100T could be considered to "win" is in thermal and power characteristics. Its 35-watt TDP is significantly lower than the Ultra 5's 65-watt TDP, making it easier to cool in small form factor systems. However, the benchmark data does not record any power efficiency metrics, so this advantage is inferred from the specifications alone.

Architecture Differences

The architectural gap between these two processors is substantial. The Core i3-14100T is based on Raptor Lake, specifically the Raptor Lake Refresh generation, built on Intel's 10 nm process. It is a monolithic design with a die size of 163 mm². The Core Ultra 5 225T, in contrast, uses the Arrow Lake architecture, built on TSMC's 3 nm process. This is a fundamental shift in manufacturing, with the Ultra 5 using a smaller, more advanced node. The Ultra 5's die is larger at 243 mm², and it packs 17,800 million transistors, a figure not listed for the i3-14100T.

The core configurations differ dramatically. The i3-14100T has 4 cores and 8 threads, meaning it uses Hyper-Threading to reach 8 threads from 4 physical cores. The Ultra 5 225T has 10 cores and 10 threads, indicating it does not use Hyper-Threading. This is a notable design choice; the Ultra 5's 10 physical cores provide more raw throughput without the need for simultaneous multi-threading.

Cache hierarchies also diverge. The i3-14100T has 80 KB of L1 cache per core, 1.25 MB of L2 per core, and 12 MB of shared L3 cache. The Ultra 5 225T has 192 KB of L1 per core, 3 MB of L2 per core, and 20 MB of shared L3 cache. The larger caches on the Ultra 5, especially the 20 MB L3, help feed its 10 cores and improve performance in cache-sensitive workloads.

Memory support is another major difference. The i3-14100T supports both DDR4 and DDR5 memory, giving users flexibility to reuse older RAM. The Ultra 5 225T supports only DDR5, and its memory bandwidth is rated at 102.4 GB/s. The i3-14100T's memory bandwidth is not listed in the data, but the Ultra 5's dual-channel DDR5 interface is clearly a more modern and faster configuration.

The Ultra 5 also supports ECC memory, a feature that is notably absent on the i3-14100T. This makes the Ultra 5 more suited for error-sensitive workloads like data processing or scientific computing, though both are desktop parts.

PCIe support differs as well. The i3-14100T provides Gen 5, 16 lanes from the CPU. The Ultra 5 225T offers Gen 5, 20 lanes, giving it more bandwidth for expansion cards and NVMe storage.

Integrated graphics also change. The i3-14100T uses UHD Graphics 730, a basic GPU for display output. The Ultra 5 225T uses Arc Xe-LPG Graphics 16EU, which is a more capable graphics solution, though specific performance numbers are not in the data.

Head-to-Head Benchmarks

The head-to-head benchmark results are unambiguous: the Core Ultra 5 225T wins every single test. The largest margin comes in Passmark's find prime numbers test, where the Ultra 5 scores 284 versus the i3-14100T's 56, a delta of 80.3%. This test is heavily dependent on integer math and core count, and the Ultra 5's 10 cores dominate.

Floating point math is another huge win for the Ultra 5. Its score of 82751 is 62.1% higher than the i3-14100T's 31379. This indicates a much stronger FPU, likely due to the newer architecture and higher core count. Data encryption also shows a massive gap: the Ultra 5 scores 18289 versus 7881, a 56.9% difference, suggesting the Ultra 5 has better support for cryptographic instructions.

The Cinebench tests, which are standard for measuring CPU rendering performance, show a consistent pattern. In Cinebench R23 multi-core, the Ultra 5 scores 21971 versus 11612, a 47.1% advantage. In single-core, the Ultra 5 scores 3101 versus 1639, also a 47.1% lead. The Cinebench R15 and R20 tests show nearly identical deltas, with the Ultra 5 leading by approximately 47.1% to 47.2% in both multi-core and single-core tests across all versions.

Passmark's data compression test shows the Ultra 5 scoring 233998 versus 152636, a 34.8% lead. Integer math is a smaller win at 32.3%, with the Ultra 5 scoring 59543 versus 40292. The multithread test shows a 46.1% lead for the Ultra 5 (25358 versus 13662), and physics simulation shows a 52.6% lead (2053 versus 973).

The smallest margin is in Passmark's single-thread test, where the Ultra 5 leads by only 19.5% (4348 versus 3498). This is still a significant gap, but it shows that the i3-14100T's boost clock of 4.40 GHz helps it stay competitive in single-threaded tasks, even though the Ultra 5's 4.90 GHz boost clock is higher.

Random string sorting shows a 45.9% lead for the Ultra 5 (28774 versus 15579), and extended instructions show a 48.1% lead (20083 versus 10414). In every case, the Ultra 5's advantage is substantial, ranging from roughly one-fifth to more than four-fifths.
