Intel Core 5 330 vs Intel Core i5-14400T Comparison

Head-to-Head Benchmarks

The head-to-head data presents a lopsided contest. The Intel Core i5-14400T wins 14 of the 17 recorded tests, while the Intel Core 5 330 takes only 3. The most dramatic margin belongs to the i5-14400T in PassMark integer math, where it scores 65667 against 33258, a 49.4% advantage. That gap reflects the i5's higher core count and thread count, which directly feed integer-heavy workloads.

The Cinebench suite shows a consistent pattern. Across R15, R20, and R23, the i5-14400T leads by 23.5% in both single-core and multi-core runs. For example, Cinebench R23 multi-core shows 17189 for the i5 versus 13150 for the Core 5 330. Single-core R23 is similarly one-sided: 2426 against 1856. The uniformity of that 23.5% delta across every Cinebench test suggests a systematic advantage rather than workload-specific behavior.

PassMark multithread follows the same trend. The i5-14400T posts 20223, while the Core 5 330 manages 15471, a 23.5% deficit. Data compression is even worse for the Core 5 330, which scores 145287 versus 235636 for the i5, a 38.3% gap. Random string sorting shows a 29.4% difference in favor of the i5 (25181 vs 17771). Data encryption is closer, with the i5 ahead by 16.4% (13244 vs 11076). Extended instructions narrow further to 12% (14562 vs 12808), and floating-point math shows a 10.7% edge for the i5 (49139 vs 43885). Physics is nearly a tie: 1244 for the i5 versus 1201 for the Core 5 330, a 3.5% margin.

The Core 5 330 does claim a few wins. Its most notable is PassMark find prime numbers, where it scores 114 against 73, a 56.2% advantage. That is the single largest positive delta for either chip in any test. It also wins PassMark single-thread, scoring 4088 versus 3512, a 16.4% lead. The same test appears twice in the database (passmark_single_thread and passmark_singlethread), and both record identical results. Those wins indicate that the Wildcat Lake design has a strong single-thread capability despite its lower overall score profile.

The average benchmark score reinforces the overall picture. The i5-14400T sits at 27166, while the Core 5 330 lands at 18345. The percentile ranking also favors the i5: it sits at the 79th percentile of all CPUs, while the Core 5 330 sits at the 72nd. The nearest rivals for the Core 5 330 include the Intel Core i3-14100 (avg score 18318, delta 0.1%) and the Intel Core 3 305 (18302, delta 0.2%), both essentially tied. The i5-14400T's nearest rivals are far higher, including the Intel Core i9-9900K (27097, delta 0.3%) and AMD Ryzen 7 5700G (27051, delta 0.4%). That places the i5 in a different performance tier entirely.

Architecture Differences

The two processors come from different Intel generations and target different market segments. The Intel Core 5 330 uses the Wildcat Lake codename, built on a 3 nm process node. It is marked as a mobile segment part, socketed for Intel BGA 1516. The Intel Core i5-14400T belongs to the Raptor Lake-R family, a 10 nm part in the 14th Gen series, designed for desktop use on Intel Socket 1700.

Core and thread counts diverge sharply. The Core 5 330 has 6 cores and 6 threads, meaning no hyperthreading. The i5-14400T has 10 cores and 16 threads, which implies a hybrid arrangement of performance and efficiency cores, though the database does not specify the exact split. The thread advantage alone explains much of the multi-threaded benchmark delta.

Cache hierarchies also differ. The Core 5 330 has 192 KB of L1, 2.5 MB of L2, and 6 MB of shared L3. The i5-14400T lists L1 as 80 KB per core, L2 as 1.25 MB per core, and L3 as 20 MB shared. The i5's total cache capacity is substantially larger, which benefits workloads that repeatedly access the same data. The die size for the i5 is listed at 215 mm²; the Core 5 330 has no die size recorded.

Memory support separates the two as well. The Core 5 330 supports DDR5 and LPDDR5X with a single-channel memory bus and a recorded bandwidth of 59.7 GB/s. The i5-14400T supports DDR4 and DDR5 with a dual-channel bus, but no bandwidth figure is recorded. ECC memory is supported only on the i5; the Core 5 330 does not list ECC support. PCIe lanes differ: the Core 5 330 offers Gen 4 with 6 CPU lanes, while the i5-14400T offers Gen 5 with 16 CPU lanes. The i5's newer PCIe generation and greater lane count give it more headroom for discrete GPUs and NVMe storage.

Integrated graphics also differ. The Core 5 330 has Intel Xe3 Graphics with 2 Xe cores. The i5-14400T uses UHD Graphics 730. The database provides no direct benchmark comparison for the iGPU, so the performance relationship is not quantified. The Core 5 330's base clock is 1.50 GHz with a boost of 4.60 GHz. The i5-14400T also starts at 1.50 GHz but boosts to 4.50 GHz, slightly lower. The TDP figures are 15 W for the Core 5 330 and 35 W for the i5-14400T, reflecting the mobile versus desktop positioning.

Release dates place the Core 5 330 at 2026-04-15 and the i5-14400T at 2024-01-07. Both are marked as Active production. The Core 5 330 has no multiplier unlock; neither does the i5. Part numbers are SAE3G for the Core 5 330 and SRN3N for the i5.

FAQ

Q: What explains the i5-14400T's lead in data compression?

A: The i5 scores 235636 in PassMark data compression versus 145287 for the Core 5 330, a 38.3% gap. The i5's 10 cores and 16 threads provide more parallel execution resources for compression workloads.

Q: Are these processors in the same performance percentile?

The Verdict

The data supports a clear split. The Intel Core i5-14400T dominates in multi-threaded and most single-threaded workloads, winning 14 of 17 tests. Its 10 cores, 16 threads, larger L3 cache, and dual-channel memory give it decisive advantages in compression, integer math, and Cinebench rendering. For desktop users running production workloads, the i5-14400T is the stronger choice based on benchmark outcomes alone.

The Intel Core 5 330 has a narrower set of strengths. It wins PassMark single-thread by 16.4%, which suggests it has a faster per-core execution engine in certain instruction patterns. Its 56.2% win in find prime numbers indicates a specific arithmetic advantage. However, its 6 cores and 6 threads limit its performance in parallel tasks. Its 15 W TDP and mobile BGA socket point to a different use case, one where low power and compact integration matter more than raw throughput.

The percentile data reinforces the verdict. The i5-14400T's average score of 27166 places it near the Intel Core i9-9900K and AMD Ryzen 7 5700G. The Core 5 330's 18345 average places it alongside the Intel Core i3-14100 and Core 3 305. Those are different performance strata. The i5-14400T is a high-midrange desktop part; the Core 5 330 is a mobile part that trades cores and cache for efficiency.

Where Each One Wins

The i5-14400T wins in every multi-threaded category that involves sustained parallel execution. Cinebench rendering, PassMark multithread, data compression, integer math, and random string sorting all favor the i5 by margins from 12% to 49.4%. Its dual-channel memory bus and 20 MB L3 cache provide the bandwidth and capacity that these workloads require. For anyone running video encoding, 3D rendering, or database-style data manipulation, the i5-14400T is the clear performer.

The i5 also takes most single-thread tests in the Cinebench suite, with a 23.5% lead in R15, R20, and R23 single-core. That indicates its Raptor Lake cores have a higher sustained single-core throughput in rendering workloads. The PassMark physics test is nearly a tie, with the i5 ahead by only 3.5%, so the i5's lead is not universal in lightly threaded tasks.

The Core 5 330 wins where its architecture appears to excel: PassMark single-thread (4088 vs 3512) and PassMark find prime numbers (114 vs 73). The single-thread win is notable because it beats a higher-tier desktop part in that specific metric. The prime number test likely reflects a particular integer division or modular arithmetic path where Wildcat Lake's 3 nm process and newer core design outperform. The Core 5 330 also keeps the gap modest in floating-point math, trailing by only 10.7%, and in extended instructions, trailing by 12%.

For a mobile platform, the Core 5 330's 15 W TDP and single-channel memory make sense as a low-power design. Its 6 cores and 6 threads are sufficient for bursty single-thread tasks, and its 4.60 GHz boost clock is the highest of the two parts. But the benchmark record shows that the i5-14400T, despite a lower boost clock, delivers superior performance in nearly every measurable category. The data does not suggest that the Core 5 330 can compensate for its core and cache deficits in multi-threaded work. The i5-14400T is the winner in overall performance, while the Core 5 330 holds specific single-thread and energy-oriented niches.
