Intel Core 5 320 vs Intel Core Ultra 7 270K Plus Comparison

Intel Core 5 320 and Intel Core Ultra 7 270K Plus occupy entirely different positions in Intel’s lineup. The Core 5 320 is a mobile processor designed for thin-and-light systems, built on the Wildcat Lake codename with 6 cores and 6 threads, a 1.50 GHz base clock, and a 4.60 GHz boost clock. The Core Ultra 7 270K Plus is a desktop part from the Arrow Lake Refresh family, featuring 24 cores and 24 threads, a 3.70 GHz base clock, and a 5.50 GHz boost clock. The benchmark data shows a decisive performance gap, with the Core Ultra 7 winning all 17 head-to-head tests. That outcome is expected given the core count and clock speed differences, but the magnitude of the margin varies by workload, which reveals where each processor has relative strengths.

Where Each One Wins

The Core Ultra 7 270K Plus wins every recorded benchmark. The Core 5 320 does not win a single test in the database. That is a complete sweep across all 17 head-to-head comparisons, including Cinebench R15, R20, and R23, plus the full PassMark suite. The closest margins appear in single-threaded tests, where the Core Ultra 7 leads by roughly 20 to 22 percent. The largest margins appear in heavily multithreaded workloads, such as Cinebench R23 multicore, where the Core Ultra 7 leads by 86 percent.

The Core 5 320, despite losing all tests, still shows a distinct profile. Its single-thread scores are competitive relative to its own multicore scores. In Cinebench R23, the Core 5 320 scores 1926 in single-core and 6197 in multicore, giving a multicore-to-single-core ratio of about 3.2. The Core Ultra 7 scores 2439 in single-core and 44253 in multicore, a ratio of about 18.1. That means the Core Ultra 7 scales far better with additional cores, while the Core 5 320 relies more on per-core efficiency. For workloads that use few threads, the Core 5 320 is not far behind in relative terms, though it is still slower in absolute score.

The data also shows distinct strengths in specific PassMark subtests. The Core Ultra 7 excels in data compression, scoring 804322 versus 148779, a difference of 81.5 percent. In floating point math, the Core Ultra 7 scores 229491 versus 42440, an 81.5 percent lead. The Core 5 320’s best relative showing is in physics, where it scores 1221 versus 4064, a 70 percent deficit, the smallest margin in the entire PassMark suite. That suggests the Core 5 320’s modest core count is less of a disadvantage in physics simulation than in other threaded tasks.

Architecture Differences

The two processors share a 3 nm process node, but the similarity ends there. The Core 5 320 is fabricated by Intel, while the Core Ultra 7 270K Plus is fabricated by TSMC. The Core 5 320 uses the Wildcat Lake codename and belongs to the Core 5 generation. The Core Ultra 7 uses Arrow Lake Refresh and belongs to the Core Ultra Series 2 family. These are different silicon designs targeting different sockets and market segments.

The Core 5 320 has 6 cores and 6 threads, with no hyperthreading. It uses an Intel BGA 1516 socket, which is a mobile package. The Core Ultra 7 has 24 cores and 24 threads, also with no hyperthreading, but uses Intel Socket 1851 for desktop platforms. The Core Ultra 7 has a much larger transistor count at 17,800 million transistors and a die size of 243 mm². The Core 5 320’s transistor count and die size are not recorded in the database.

Cache configurations differ substantially. The Core 5 320 has 192 KB of L1 cache, 2.5 MB of L2 cache, and 6 MB of shared L3 cache. The Core Ultra 7 has 192 KB of L1 cache per core, 3 MB of L2 cache per core, and 36 MB of shared L3 cache. The Core Ultra 7’s L3 cache is six times larger, which helps with data-heavy workloads. The L2 cache is also larger per core, at 3 MB versus 2.5 MB total for the Core 5 320.

Memory support also diverges. The Core 5 320 supports DDR5 and LPDDR5X, with a single-channel memory bus and 59.7 GB/s of bandwidth. The Core Ultra 7 supports DDR5 only, with a dual-channel memory bus and 115.2 GB/s of bandwidth. The Core Ultra 7 also supports ECC memory, while the Core 5 320 does not. PCIe connectivity differs too: the Core 5 320 uses Gen 4 with 6 lanes, while the Core Ultra 7 uses Gen 5 with 20 lanes. Integrated graphics are different as well, with the Core 5 320 using Intel Xe3 Graphics with 2 Xe cores, and the Core Ultra 7 using Arc Xe-LPG Graphics with 64 EU.

The Core Ultra 7 has an unlocked multiplier, while the Core 5 320 does not. The Core Ultra 7 is a desktop processor with a 125 W TDP, while the Core 5 320 is a mobile part with a 15 W TDP. The release dates differ by about a month, with the Core 5 320 launching on April 15, 2026, and the Core Ultra 7 launching on March 10, 2026. The launch MSRP for the Core 5 320 is $340, and for the Core Ultra 7 it is $299.

Head-to-Head Benchmarks

The Cinebench results show the largest gaps in multicore workloads. In Cinebench R15 multicore, the Core Ultra 7 scores 6656 versus the Core 5 320’s 1054, a deficit of 84.2 percent. In Cinebench R20 multicore, the scores are 24461 versus 5462, a 77.7 percent gap. In Cinebench R23 multicore, the scores are 44253 versus 6197, an 86 percent gap. These are massive differences, driven by the Core Ultra 7’s 24 cores versus the Core 5 320’s 6 cores, plus the Core Ultra 7’s higher clock speeds.

Single-core Cinebench results are closer but still favor the Core Ultra 7. In Cinebench R15 single-core, the Core Ultra 7 scores 354 versus 276, a 22 percent lead. In Cinebench R20 single-core, the scores are 3453 versus 771, a 77.7 percent lead. In Cinebench R23 single-core, the scores are 2439 versus 1926, a 21 percent lead. The R20 single-core result stands out because the margin is much larger than in R15 or R23. That may reflect differences in how the workloads scale with the Core Ultra 7’s higher boost clock of 5.50 GHz versus the Core 5 320’s 4.60 GHz.

PassMark results follow a similar pattern. In data compression, the Core Ultra 7 scores 804322 versus 148779, an 81.5 percent lead. In data encryption, the scores are 59097 versus 10984, an 81.4 percent lead. In extended instructions, the scores are 63506 versus 13262, a 79.1 percent lead. In find prime numbers, the scores are 615 versus 110, an 82.1 percent lead. In floating point math, the scores are 229491 versus 42440, an 81.5 percent lead. In integer math, the scores are 175986 versus 32323, an 81.6 percent lead. In multithread, the scores are 68574 versus 15450, a 77.5 percent lead. In physics, the scores are 4064 versus 1221, a 70 percent lead. In random string sorting, the scores are 96945 versus 18038, an 81.4 percent lead. In single thread, the scores are 5068 versus 4045, a 20.2 percent lead.

The single-thread PassMark result shows the smallest margin in the entire comparison. A 20.2 percent lead in single-thread performance is meaningful, but it is far smaller than the 70 to 86 percent gaps seen in threaded tests. This indicates that the Core 5 320’s per-core performance is respectable, but its lack of cores and threads limits it in any parallel workload. The Core 5 320’s average benchmark score of 18023 places it at the 72nd percentile of all CPUs, while the Core Ultra 7’s average score of 93785 places it at the 96th percentile.
