Intel Core 5 330 vs Intel Core 7 253PTE Comparison

Where Each One Wins

The benchmark split is stark: the Intel Core 7 253PTE wins 14 of 17 head-to-head tests, while the Intel Core 5 330 wins only 3. The Core 7 253PTE dominates every Cinebench workload, both single-core and multi-core, and nearly every PassMark test. Its wins are broad and decisive, covering rendering, compression, encryption, math, sorting, and multithreaded throughput. The Core 5 330, by contrast, takes narrow victories in two related single-thread PassMark tests and one prime-number search test. Those wins are real but isolated, and they do not offset the scale of the Core 7 253PTE's advantages elsewhere.

The Core 5 330's wins come in PassMark single-thread (4088 vs 3794, a 7.7% advantage) and in PassMark find prime numbers (114 vs 82, a 39% advantage). The single-thread score is notable because the Core 7 253PTE has a higher boost clock (5.40 GHz vs 4.60 GHz), yet the Core 5 330 still posts the higher score in that specific test. The prime-number result is an outlier within the broader data, as the Core 7 253PTE wins every other PassMark compute test by a wide margin. The data indicates the Core 5 330 has a specific strength in lightly threaded integer loops, but this strength does not carry over to Cinebench single-core, where the Core 7 253PTE leads by 38.2%.

For multithreaded work, the Core 7 253PTE is in a different class. Cinebench R23 multi-core shows 21276 vs 13150, a 38.2% gap. PassMark integer math shows a 72.2% gap (119552 vs 33258), the largest delta in the entire comparison. Data compression also shows a massive 47.3% gap (275828 vs 145287). The use-case split is simple: the Core 7 253PTE is the choice for any workload that scales with cores, threads, or sustained throughput, while the Core 5 330 only wins narrow single-threaded integer tasks and prime-number searches.

Architecture Differences

The two processors come from different Intel lines and use fundamentally different designs. The Core 5 330 is a Wildcat Lake part on a 3 nm node, built for mobile, with 6 cores and 6 threads. The Core 7 253PTE is a Bartlett Lake part on a 10 nm node, built for desktop, with 10 cores and 20 threads. The thread count difference is the single most important architectural factor: the Core 7 253PTE supports hyper-threading, doubling its 10 cores into 20 threads, while the Core 5 330 has no hyper-threading and runs 6 threads on 6 cores.

Cache configurations differ substantially. The Core 5 330 has 192 KB of L1, 2.5 MB of L2, and 6 MB of shared L3. The Core 7 253PTE has 80 KB of L1 per core, 2 MB of L2 per core, and 33 MB of shared L3. The Core 7 253PTE's L3 cache is over five times larger in absolute terms, and its per-core L2 allocation is also larger. These cache differences help explain why the Core 7 253PTE wins data compression and random string sorting, workloads that benefit from larger working sets in cache.

Memory support also diverges. The Core 5 330 supports DDR5 and LPDDR5X on a single-channel bus with 59.7 GB/s bandwidth. The Core 7 253PTE supports DDR4 and DDR5 on a dual-channel bus with 89.6 GB/s bandwidth. The dual-channel configuration and higher bandwidth give the Core 7 253PTE a clear memory throughput advantage, which feeds into its multi-core wins. The Core 5 330 also lacks ECC memory support, while the Core 7 253PTE supports ECC, a differentiator for reliability-sensitive workloads.

PCIe connectivity differs: the Core 5 330 uses Gen 4 with 6 CPU lanes, while the Core 7 253PTE uses Gen 5 with 16 CPU lanes. Integrated graphics also differ, with the Core 5 330 using Intel Xe3 Graphics (2 Xe) and the Core 7 253PTE using UHD Graphics 730. The sockets are incompatible: Intel BGA 1516 for the Core 5 330, Intel Socket 1700 for the Core 7 253PTE. The Core 7 253PTE runs at a higher TDP of 45 watts versus 15 watts for the Core 5 330, reflecting its desktop orientation and higher power envelope.

Head-to-Head Benchmarks

The largest single delta in the comparison is PassMark integer math, where the Core 7 253PTE scores 119552 against 33258 for the Core 5 330, a 72.2% lead. This is not a marginal difference; it reflects the combined effect of more cores, more threads, and higher clocks in integer-heavy computation. The next largest gap is in data compression, 275828 vs 145287, a 47.3% advantage for the Core 7 253PTE. Compression workloads are sensitive to both core count and cache size, and the Core 7 253PTE has advantages in both areas.

Cinebench results are consistent across all versions. In R15 multi-core, the Core 7 253PTE scores 2144 vs 1325, a 38.2% lead. In R20 multi-core, it scores 8935 vs 5523, also 38.2%. In R23 multi-core, it scores 21276 vs 13150, again 38.2%. Single-core Cinebench results show the same pattern: R15 single-core is 302 vs 186, R20 single-core is 1261 vs 779, and R23 single-core is 3003 vs 1856, all with a 38.2% delta. The consistency of the 38.2% delta across all six Cinebench tests suggests a fixed performance ratio between the two parts in rendering workloads, independent of the specific benchmark version.

PassMark multithread shows 25031 vs 15471, a 38.2% gap, matching the Cinebench multi-core deltas. Random string sorting shows 28227 vs 17771, a 37% gap. Floating point math shows 67209 vs 43885, a 34.7% gap. Extended instructions show 17099 vs 12808, a 25.1% gap. Data encryption shows 15500 vs 11076, a 28.5% gap. Physics shows 1318 vs 1201, a smaller 8.9% gap, but still a win for the Core 7 253PTE.

The Core 5 330's two wins are PassMark single-thread (4088 vs 3794, 7.7%) and PassMark find prime numbers (114 vs 82, 39%). The prime-number win is the only test where the delta exceeds 10% in favor of the Core 5 330, and it is an outlier within the broader PassMark suite. The single-thread win is modest and does not appear in Cinebench single-core, where the Core 7 253PTE leads decisively.

The Verdict

The data points to a clear verdict: the Intel Core 7 253PTE is the superior processor for almost every measured workload. It wins 14 of 17 benchmarks, including all Cinebench tests, all PassMark multithreaded tests, and all PassMark compute tests except prime-number searching. Its 20 threads, 33 MB of L3 cache, dual-channel memory, and 89.6 GB/s bandwidth give it a decisive edge in rendering, compression, encryption, and integer math. The Core 5 330 cannot match this breadth of performance; its wins are confined to single-thread PassMark and prime-number searching, which are narrow slices of the benchmark suite.

The Core 5 330's role is limited to specific use cases. Its 7.7% single-thread PassMark win and 39% prime-number win suggest it has a niche in certain lightweight integer workloads, but those advantages do not appear in Cinebench single-core, where the Core 7 253PTE leads by 38.2%. For anyone choosing between these two based on the recorded data, the Core 7 253PTE is the default pick for productivity, content creation, or any task that uses more than one thread. The Core 5 330 is only preferable if the workload closely matches its two winning tests, and even then, the overall benchmark average (34962 for the Core 7 253PTE vs 18345 for the Core 5 330) heavily favors the larger part.

The percentile rankings reinforce the gap: the Core 7 253PTE sits at the 84th percentile among all CPUs, while the Core 5 330 sits at the 72nd percentile. The Core 7 253PTE's nearest rivals are Intel Core i7-13800H and Intel Core i9-12900HX, with deltas of -0.1%, indicating it performs at the level of high-end mobile HX parts. The Core 5 330's nearest rivals include the Intel Core i3-14100 and Intel Core i3-13100, with deltas of 0.1% and -0.2%, placing it in the budget desktop class. The data confirms these are different tiers, not close competitors.
