Intel Core 5 320 vs Intel Core i5-1334U Comparison

Head-to-Head Benchmarks

The data presents a remarkably split picture. In the 17 head-to-head comparisons recorded, the Intel Core 5 320 takes 13 wins, while the Intel Core i5-1334U secures only 4. Yet the nature of those wins tells the real story—this is not a one-sided generational leap, but a fundamental shift in workload character.

The i5-1334U's victories are concentrated in multi-core rendering and integer-heavy tasks. Its most dominant result comes in PassMark integer math, where it scores 50,374 against the Core 5 320's 32,323—a 55.8% advantage. Cinebench R23 multi-core shows a 39.4% lead (8,641 vs 6,197), and Cinebench R15 multi-core follows with a 48.9% margin (1,569 vs 1,054). Data compression is a narrower win: 150,568 vs 148,779, just 1.2% ahead.

The Core 5 320's wins are more widespread and often larger. Its biggest edge is in PassMark find prime numbers, where it scores 110 against the i5-1334U's 39—a 64.5% difference. Extended instructions show a 35.4% lead (13,262 vs 8,563), and physics simulation sees a 40.9% advantage (1,221 vs 722). Floating-point math goes 42,440 vs 34,474, an 18.8% margin. The single-core picture is consistently in its favor: 1,926 vs 1,727 in Cinebench R23 single-core (10.3% ahead), 771 vs 654 in R20 single-core (15.2%), and 276 vs 241 in R15 single-core (12.7%).

Interestingly, the multi-core results are not uniform. The Core 5 320 wins Cinebench R20 multi-core (5,462 vs 4,638, a 15.1% lead) and PassMark multithread (15,450 vs 13,410, 13.2% ahead), yet loses R23 multi-core decisively. This inconsistency points to different scaling behavior under varying thread counts and instruction mixes—the i5-1334U's 10 cores and 12 threads appear to scale better in the R23 workload specifically, while the Core 5 320's 6 cores and 6 threads handle other multi-threaded tests more efficiently.

Data encryption is another Core 5 320 win at 10,984 vs 9,377 (14.6%), and random string sorting shows a modest 6.1% edge (18,038 vs 16,933). The overall average benchmark scores are nearly identical—18,154 for the i5-1334U and 18,023 for the Core 5 320—with the i5-1334U holding a 0.7% edge per the nearestRivals delta. Both sit at the 72nd percentile among all CPUs.

Architecture Differences

The underlying designs explain the divergent results. The Intel Core i5-1334U is built on Raptor Lake-U, a 10 nm Intel process. It implements a hybrid configuration with 10 cores and 12 threads, combining performance and efficiency cores. Its cache hierarchy is split: 80 KB L1 per core, 1.25 MB L2 per core, and 12 MB shared L3.

The Intel Core 5 320 uses the Wildcat Lake architecture on a 3 nm process. It is a fundamentally different design: 6 cores and 6 threads, meaning no hyper-threading. Its cache layout is also distinct—192 KB L1 total, 2.5 MB L2 total, and only 6 MB shared L3. Despite having half the cores and half the threads, the Core 5 320's smaller L3 is offset by a more advanced process node and likely a newer microarchitecture.

Memory support diverges sharply. The i5-1334U supports DDR4 and DDR5 over a dual-channel bus. The Core 5 320 supports DDR5 and LPDDR5X, but only on a single-channel bus, with a rated memory bandwidth of 59.7 GB/s. This could explain why the i5-1334U wins integer math—multi-channel memory bandwidth helps feed its higher core count.

Socket compatibility is a non-issue for buyers, but the technical split is notable: the i5-1334U uses Intel BGA 1744, while the Core 5 320 uses Intel BGA 1516. PCIe connectivity differs as well, with the i5-1334U offering Gen 4 with 8 CPU lanes versus the Core 5 320's Gen 4 with 6 lanes.

Integrated graphics take different approaches. The i5-1334U carries Iris Xe Graphics with 80 execution units, while the Core 5 320 uses Intel Xe3 Graphics with 2 Xe cores. Neither is a gaming powerhouse, but the newer Xe3 design in the Core 5 320 likely benefits from architectural improvements.

Both CPUs share the same 15 W TDP, same 4.60 GHz boost clock, and same $340 launch MSRP. The base clocks differ slightly: 1300 MHz for the i5-1334U versus 1500 MHz for the Core 5 320. Neither has an unlocked multiplier, and both are currently Active in production.

The Verdict

The benchmark data supports a clear but nuanced recommendation. For users running single-threaded applications, the Intel Core 5 320 is the superior choice. Its single-core wins span every Cinebench version tested and PassMark single-thread, with margins ranging from 10.3% to 17.3%. The extended instructions, floating-point math, physics, and encryption results all favor the Core 5 320, making it the better pick for scientific computing, encryption workloads, and general responsiveness.

For multi-core integer-heavy tasks, the Intel Core i5-1334U holds the advantage. Its 55.8% lead in integer math and 39.4% lead in Cinebench R23 multi-core are substantial. Users running code compilation, data processing, or any workload that scales across many threads will benefit from the i5-1334U's 10 cores and 12 threads. The 48.9% margin in R15 multi-core reinforces this strength.

The average benchmark scores are effectively equivalent—18,154 vs 18,023—and both CPUs occupy the same 72nd percentile. The choice hinges entirely on workload profile. The Core 5 320 offers better per-thread performance and wins 13 of 17 direct comparisons. The i5-1334U offers more raw thread count and wins the workloads that exploit it. Neither is a universal winner; the data indicates the Core 5 320 is the more broadly capable processor for typical mixed usage, while the i5-1334U serves specific multi-threaded scenarios better.
