Intel Core Ultra 5 225T vs Intel Core Ultra 5 245 Comparison

Head-to-Head Benchmarks

The benchmark database records a one-sided comparison between the Intel Core Ultra 5 225T and the Intel Core Ultra 5 245. Across all 17 recorded head-to-head tests, the Core Ultra 5 245 wins, with the 225T securing no victories. The largest gaps appear in heavily parallel workloads, where the 245's additional cores and higher clocks produce substantial margins.

In Cinebench R23 multi-core, the 245 scores 32,924 against the 225T's 21,971, a 33.3% deficit for the 225T. The same 33.3% delta appears across every Cinebench generation tested: R15 multi-core (3,318 vs 2,214), R20 multi-core (13,828 vs 9,227), and the single-core variants R15 (468 vs 312), R20 (1,952 vs 1,302), and R23 (4,648 vs 3,101). The consistency of this exact percentage across all six Cinebench tests suggests a uniform clock and core advantage rather than workload-specific behavior.

PassMark tests show a wider spread of deltas. Data compression yields the largest gap: 400,942 for the 245 versus 233,998 for the 225T, a 41.6% difference. Random string sorting follows closely at 41.4% (49,140 vs 28,774), and data encryption trails at 39.5% (30,236 vs 18,289). Extended instructions show a 39.7% gap (33,304 vs 20,083). These four tests cluster around the 39% to 42% range, indicating tasks that scale strongly with additional cores and memory bandwidth.

Integer math shows a 34.7% delta (91,187 vs 59,543), while floating-point math records 31.4% (120,548 vs 82,751). PassMark multi-thread, which aggregates overall parallel performance, shows 38,706 versus 25,358, a 34.5% gap. Find prime numbers, a test sensitive to both integer throughput and cache behavior, shows the narrowest multi-core margin at 22.2% (365 vs 284). Physics simulation records 2,569 versus 2,053, a 20.1% delta.

The single-threaded PassMark results present a different picture. The 245 scores 4,394, while the 225T scores 4,348, a mere 1% difference. This is the smallest gap in the entire dataset. The Cinebench single-core tests, however, show a much larger 33.3% delta, which is unusual. The discrepancy between PassMark single-thread and Cinebench single-core suggests the 225T's lower boost clock (4.90 GHz versus 5.10 GHz) impacts Cinebench's specific instruction mix more heavily, while PassMark's single-thread workload is less sensitive to the 200 MHz clock difference.

Where Each One Wins

The data indicates the Core Ultra 5 245 wins in every measured category. There is no benchmark in the database where the 225T records a higher score. The question becomes not which processor wins, but how the margin varies by workload type.

For single-threaded productivity, the 245 holds a slim edge. PassMark single-thread shows only a 1% difference, meaning the 225T remains competitive for lightly threaded applications. Users running older software that relies on one or two cores would see nearly identical performance between these two parts.

For multi-threaded rendering, the 245 dominates. Cinebench R23 multi-core shows the 225T trailing by a full third. Any workload that scales across cores, such as video encoding, 3D rendering, or scientific simulation, will complete substantially faster on the 245. The 14-core configuration versus 10 cores provides a clear structural advantage.

For data-heavy tasks, the 245's lead grows even larger. Data compression, encryption, and sorting all show deltas above 39%. These workloads benefit from the 245's larger L3 cache (24 MB versus 20 MB) and additional cores. The 225T's 20 MB shared L3 cache is sufficient for moderate data sets, but the 245's extra 4 MB reduces cache misses in compression and sorting workloads.

The narrowest multi-core margin appears in physics and prime number finding, at roughly 20% to 22%. These tasks are more dependent on memory latency and per-core efficiency than raw core count, so the 245's advantage shrinks but remains decisive.

Architecture Differences

Both processors belong to the Core Ultra Series 2 family, built on Arrow Lake architecture with the Arrow Lake-S codename. They share the same TSMC 3 nm process node, transistor count of 17,800 million, and die size of 243 mm². The foundry, socket (Intel Socket 1851), and generation designation (Ultra 5, Arrow Lake) are identical.

The core configurations diverge significantly. The 225T has 10 cores and 10 threads, while the 245 has 14 cores and 14 threads. Neither supports multithreading, so thread count equals core count. The 245's four additional cores explain most of its multi-core performance advantage.

Clock speeds also differ. The 225T has a base clock of 2.50 GHz and a boost clock of 4.90 GHz. The 245 operates at 3.50 GHz base and 5.10 GHz boost. The 1.00 GHz base clock difference is substantial, while the 0.20 GHz boost gap is modest. Both parts have a 65 W TDP, meaning the 245 delivers higher performance within the same power envelope.

Cache hierarchies are similar in structure but differ in capacity. Both have 192 KB L1 per core and 3 MB L2 per core. The L3 cache is shared, with the 225T offering 20 MB and the 245 offering 24 MB. The 4 MB L3 difference correlates with the extra cores, though the per-core L3 allocation (2 MB per core on the 225T, approximately 1.71 MB per core on the 245) actually favors the 225T slightly.

Memory support is identical: DDR5, dual-channel, 102.4 GB/s bandwidth. PCIe configuration matches as well, with Gen 5 and 20 lanes from the CPU. The integrated graphics differ, with the 225T using Arc Xe-LPG Graphics with 16 execution units, while the 245 uses the same architecture with 64 EU. The 245's integrated GPU has four times the execution units, which would benefit systems without a discrete graphics card.

ECC memory support is another differentiator. The 245 supports ECC memory, while the 225T does not. This makes the 245 suitable for workstation or server builds where error-correcting memory is required. The 245 also has a known part number (SRVFE), while the 225T's part number is listed as unknown.

The release dates differ. The 225T entered the database on 2024-12-31, while the 245 arrived on 2025-01-06, a six-day gap. Both remain in active production. The 245 has a launch MSRP of $270; the 225T has no recorded launch MSRP. Neither processor has an unlocked multiplier.

The Verdict

The benchmark data presents a clear hierarchy. The Intel Core Ultra 5 245 outperforms the Intel Core Ultra 5 225T in every recorded test, with multi-core margins ranging from 20.1% to 41.6%. The single-thread PassMark margin of 1% is the only area where the 225T approaches parity.

The 245's 14 cores versus 10 cores, combined with higher base and boost clocks, produces a consistent advantage across rendering, compression, encryption, and math workloads. The additional 4 MB of L3 cache and ECC support further differentiate it for professional use cases. The 64 EU integrated graphics on the 245 also provide substantially better iGPU performance than the 225T's 16 EU configuration.

The 225T's advantages are narrower. It shares the same process node, die size, and transistor count. It has the same 65 W TDP, making it equally power-efficient at idle or under load. Its per-core L3 allocation is actually higher, and its single-thread PassMark score trails by only 1%. For users with strictly single-threaded workloads, the 225T delivers nearly identical performance at a potentially lower cost (though no launch MSRP is recorded).

The percentile rankings confirm the hierarchy. The 225T sits at the 82nd percentile among all CPUs, while the 245 reaches the 90th percentile. The 225T's average benchmark score is 30,468, placing it near rivals like the Intel Core i9-11980HK (30,422, 0.2% delta) and AMD Ryzen 5 7640HS (30,390, 0.3% delta). The 245's average score of 48,995 places it near the AMD Ryzen 7 PRO 5755G (49,196, -0.4% delta) and AMD Ryzen 9 7900 (49,228, -0.5% delta). The 245 competes in a higher performance tier, roughly 60% above the 225T's average score.

For a desktop build requiring maximum throughput, the data supports the 245 without reservation. For a power-constrained or single-thread-focused system, the 225T remains viable, but the database shows no workload where it beats the 245.
