Architecture Differences

The two processors diverge sharply in core configuration and memory architecture. The Core 5 320 is a 6-core, 6-thread part based on the Wildcat Lake codename, built on a 3 nm process at Intel's foundry. The Core Ultra 7 265H is a 16-core, 16-thread part from the Arrow Lake-H family, also on a 3 nm process but fabricated by TSMC. The thread counts match core counts on both parts, meaning neither uses Hyper-Threading or similar SMT technology.

The cache hierarchy reveals a major structural difference. The Core 5 320 has 192 KB of L1 cache, 2.5 MB of L2, and 6 MB of shared L3. The Core Ultra 7 265H lists 192 KB of L1 per core, 3 MB of L2 per core, and 24 MB of shared L3. The Ultra 7's L3 cache is four times larger in total, and its per-core L2 allocation is substantially larger as well.

Memory support differs in channel count and bandwidth. The Core 5 320 uses a single-channel memory bus with 59.7 GB/s bandwidth. The Core Ultra 7 265H uses dual-channel memory with 102.4 GB/s. Both support DDR5 and LPDDR5X memory types, but the Ultra 7's wider bus gives it a clear throughput advantage. The Ultra 7 also supports ECC memory, a feature absent on the Core 5.

PCIe connectivity differs as well. The Core 5 320 provides Gen 4 with 6 CPU lanes, while the Core Ultra 7 265H provides Gen 5 with 8 CPU lanes. The integrated graphics also differ: the Core 5 uses Intel Xe3 Graphics with 2 Xe cores, while the Ultra 7 uses Arc Graphics 140T.

Clock speeds favor the Ultra 7. The Core 5 320 has a 1.50 GHz base clock and 4.60 GHz boost. The Core Ultra 7 265H has a 2.20 GHz base and 5.30 GHz boost. The power envelope also differs, with the Core 5 rated at 15 W TDP and the Ultra 7 at 28 W TDP.

The release dates are distinct: the Core Ultra 7 265H launched on 2025-01-12, while the Core 5 320 launched on 2026-04-15. Both are listed as active production parts for the mobile segment. The Core 5 320 has a launch MSRP of $340; the Core Ultra 7 265H has no recorded launch MSRP.

Head-to-Head Benchmarks

The head-to-head data shows a clean sweep: the Core Ultra 7 265H wins all 17 recorded benchmark comparisons. The Core 5 320 does not register a single victory. The magnitude of the losses varies by workload type.

The largest multi-core deficit appears in Cinebench R23 multi-core, where the Core 5 320 scores 6197 versus 19940 for the Ultra 7, a 68.9% gap. Cinebench R15 multi-core shows a similar pattern: 1054 for the Core 5 versus 2989 for the Ultra 7, a 64.7% deficit. Cinebench R20 multi-core records 5462 versus 12131, a 55% gap.

Single-core Cinebench results are closer but still favor the Ultra 7. In Cinebench R23 single-core, the Core 5 scores 1926 and the Ultra 7 scores 2080, a 7.4% difference. Cinebench R15 single-core shows 276 versus 307, a 10.1% gap. Cinebench R20 single-core shows 771 versus 1712, a 55% deficit, which is notably larger than the R23 single-core gap.

PassMark integer math heavily favors the Ultra 7: 85479 versus 32323, a 62.2% difference. Floating point math shows 109123 versus 42440, a 61.1% gap. The find prime numbers test shows 335 versus 110, a 67.2% deficit for the Core 5. Data compression shows 334711 versus 148779, a 55.6% gap. Data encryption shows 26005 versus 10984, a 57.8% difference.

The multithread PassMark test records 34027 for the Ultra 7 versus 15450 for the Core 5, a 54.6% gap. Physics scores are 2497 versus 1221, a 51.1% deficit. Extended instructions show 26805 versus 13262, a 50.5% gap. Random string sorting shows 40742 versus 18038, a 55.7% difference.

The narrowest single-thread advantage appears in PassMark single-thread tests: 4334 versus 4045, a 6.7% gap. This matches the Cinebench R23 single-core result, indicating that the Core 5's single-core performance is competitive but not equal.

The Verdict

The data indicates a decisive performance hierarchy. The Intel Core Ultra 7 265H is the stronger processor in every measured benchmark, with an average score more than double that of the Core 5 320. The 88th percentile placement versus the 72nd percentile confirms that the Ultra 7 belongs in a higher performance class.

The Core 5 320's closest rivals in the database are the AMD Ryzen 5 1600, Intel Core 5 120U, Intel Core i5-1334U, and AMD Ryzen 5 3600XT, with average scores ranging from 17891 to 18154 and deltas within 0.7% of the Core 5's 18023. This places the Core 5 in the mid-range mobile segment.

The Core Ultra 7 265H sits alongside the Intel Core 7 251TE, Intel Core i7-14650HX, Intel Core i7-12850HX, and AMD Ryzen 9 5900X, with average scores between 41376 and 41779. This is a distinctly higher performance tier, indicating the Ultra 7 competes with desktop-class and high-end mobile parts.

For workloads that depend on multi-core throughput, the choice is unambiguous. The Ultra 7 delivers nearly three times the Cinebench R23 multi-core score. For single-thread workloads, the Ultra 7 still leads, but the margin shrinks to single digits in PassMark and Cinebench R23 single-core tests.

The Core 5 320's lower TDP of 15 W versus 28 W suggests a power efficiency advantage for lighter tasks, but the benchmark data does not include power measurements. The single-channel memory bus on the Core 5 further limits its appeal for memory-intensive applications.

Specification Differences

The two processors differ in several key specifications:

• Launch MSRP: $340 for the Core 5 320; no recorded MSRP for the Ultra 7.

Where Each One Wins

The Core Ultra 7 265H wins in every recorded benchmark category. Its largest advantages appear in multi-threaded and compute-heavy workloads: Cinebench R23 multi-core (68.9% ahead), find prime numbers (67.2% ahead), integer math (62.2% ahead), and floating point math (61.1% ahead). These results indicate a strong fit for rendering, scientific computing, data compression, and encryption tasks.

The Core 5 320 shows its best relative performance in single-thread tests. In PassMark single-thread, it trails by only 6.7%. In Cinebench R23 single-core, the gap is 7.4%. This suggests that for lightly threaded applications such as basic office work, web browsing, and legacy software, the Core 5 320 delivers acceptable performance despite its lower core count.

The Core 5 320 also holds advantages in power envelope and launch MSRP. Its 15 W TDP is nearly half the Ultra 7's 28 W, and its $340 launch MSRP is the only recorded price in this comparison. These factors point to use cases prioritizing energy efficiency and cost-sensitive mobile designs.

The Core Ultra 7 265H's dual-channel memory and 102.4 GB/s bandwidth, combined with 24 MB of L3 cache, give it a clear edge in memory-bound workloads. The Gen 5 PCIe interface with 8 lanes further supports high-throughput peripherals. The Core 5 320's single-channel memory and Gen 4, 6-lane PCIe configuration limit its expansion and data movement capabilities.

For users selecting between these two mobile processors, the benchmark data consistently favors the Core Ultra 7 265H for performance-oriented tasks. The Core 5 320 remains viable for power-sensitive designs where the 15 W envelope and lower launch MSRP are priorities, but it cannot match the Ultra 7's throughput in any measured workload.
