Intel Core 7 253PQE vs Intel Core 7 350 Comparison

The Verdict

The data separates these two processors cleanly. The Intel Core 7 253PQE wins all 17 recorded head-to-head benchmarks, with lead margins ranging from a narrow 7% in PassMark single-thread tests to a dominant 308.5% in PassMark integer math. The Core 7 253PQE sits in the 91st percentile of all CPUs in the database, while the Core 7 350 lands in the 71st percentile. The 253PQE's average benchmark score of 55919 places it within 1.1% of the AMD Ryzen Threadripper PRO 3955WX, while the 350's average of 17779 sits within 0.7% of the Intel Core 5 120U. For raw compute, the 253PQE is the clear choice. The 350, however, is a mobile part with a 15 TDP, a single-channel memory bus, and a much smaller L3 cache, which points to a very different usage profile. The verdict from the recorded data: the 253PQE is for sustained heavy compute, while the 350 is for low-power mobile operation where the 253PQE cannot physically fit.

Architecture Differences

The two chips share a manufacturer and both use Intel foundry processes, but the similarity ends there. The Core 7 253PQE is built on Bartlett Lake using a 10 nm process, while the Core 7 350 uses Wildcat Lake on a 3 nm node. The 253PQE is a desktop part on Intel Socket 1700 with 10 cores and 20 threads, a 125 TDP, and a base clock of 3.50 GHz boosting to 5.70 GHz. The 350 is a mobile part on Intel BGA 1516 with 6 cores and 6 threads, a 15 TDP, and a base clock of 1.50 GHz boosting to 4.80 GHz. The thread counts are notable: the 253PQE supports Hyper-Threading-style doubling, the 350 has no thread doubling at all, so its 6 cores yield exactly 6 threads.

Cache layouts differ substantially. The 253PQE uses 80 KB of L1 per core, 2 MB of L2 per core, and 33 MB of shared L3. The 350 uses 192 KB of L1 per core, 2.5 MB of L2 per core, and only 6 MB of shared L3. Although the 350 has larger per-core L1 and L2 allocations, its total L3 is 27 MB smaller. Memory support diverges as well: the 253PQE supports DDR4 and DDR5 over a dual-channel bus with 89.6 GB/s of bandwidth and ECC enabled. The 350 supports DDR5 and LPDDR5X over a single-channel bus with 59.7 GB/s and no ECC. PCIe generation and lane counts also differ: Gen 5 with 16 CPU lanes on the 253PQE versus Gen 4 with 6 CPU lanes on the 350. Integrated graphics shift from UHD Graphics 770 on the 253PQE to Intel Xe3 Graphics with 2 Xe cores on the 350. Both parts are locked (no unlocked multiplier), both are listed as Active in production, and both are Intel parts, but they represent opposite ends of the desktop versus mobile spectrum.

Where Each One Wins

The Core 7 253PQE wins every benchmark category in the head-to-head data, but the size of each win tells a different story. The smallest margin is in single-thread performance. In PassMark single-thread, the 253PQE scores 4389 versus 4100, a lead of only 7%. The Cinebench R15 single-core result shows a larger gap of 52.7%, with the 253PQE at 446 and the 350 at 292. Cinebench R23 single-core shows 4431 versus 2046, a 116.6% lead. The 253PQE's higher boost clock of 5.70 GHz versus 4.80 GHz helps explain the single-core edge, though the PassMark single-thread result indicates the 350's 3 nm architecture narrows that gap considerably in certain workloads.

Multi-core and throughput-heavy tests show enormous leads for the 253PQE. Cinebench R23 multi-core gives 31390 versus 8030, a 290.9% margin. PassMark integer math shows 137795 versus 33734, a 308.5% lead, the largest of any recorded test. PassMark data compression gives 487335 versus 143123, a 240.5% lead. The 253PQE's 10 cores with 20 threads, 33 MB of L3, dual-channel memory at 89.6 GB/s, and 125 TDP all contribute to these results. The 350's 6 cores with 6 threads, 6 MB of L3, single-channel memory at 59.7 GB/s, and 15 TDP cannot compete in sustained parallel workloads. The 350's only advantage in the recorded data is its physical and power profile: it is a mobile chip on a BGA socket with a 15 TDP, designed for systems where the 253PQE's desktop socket and 125 TDP are not options.

Head-to-Head Benchmarks

The Cinebench suite shows a consistent pattern of massive multi-core dominance for the 253PQE. Cinebench R15 multi-core gives 3163 for the 253PQE against 1220 for the 350, a 159.3% margin. Cinebench R20 multi-core gives 13183 versus 5373, a 145.4% gap. Cinebench R23 multi-core widens to 31390 versus 8030, a 290.9% lead. Single-core results in Cinebench are also lopsided: R15 single-core shows 446 versus 292 (52.7%), R20 single-core shows 1861 versus 758 (145.5%), and R23 single-core shows 4431 versus 2046 (116.6%). The R20 single-core margin is surprisingly close to the R20 multi-core margin, indicating the 253PQE's per-core advantage is nearly as strong as its aggregate advantage in that test.

PassMark results reinforce the pattern. The largest lead in the entire head-to-head set is PassMark integer math: 137795 versus 33734, a 308.5% delta. PassMark data compression follows at 487335 versus 143123, a 240.5% margin. PassMark random string sorting gives 54222 versus 17238, a 214.5% lead. PassMark multithread shows 41656 versus 15170, a 174.6% gap. PassMark extended instructions gives 32390 versus 12045, a 168.9% margin. PassMark physics shows 2970 versus 1173, a 153.2% lead. PassMark floating point math gives 105279 versus 42809, a 145.9% gap. PassMark data encryption shows 25515 versus 10933, a 133.4% margin. PassMark find prime numbers gives 206 versus 107, a 92.5% lead. The only close result is PassMark single-thread: 4389 versus 4100, a 7% margin, which appears twice in the data under slightly different test names (passmark_single_thread and passmark_singlethread) with identical scores.

Looking at the nearest rivals in the database places both chips in context. The 253PQE's average score of 55919 is 0.2% below the Intel Core i9-14900HX, 0.6% below the AMD Ryzen AI Max 390, 0.7% below the AMD Ryzen AI 9 HX PRO 470, and 1.1% below the AMD Ryzen Threadripper PRO 3955WX. The 350's average score of 17779 is 0.5% below the Intel Core 5 221TE, 0.5% above the AMD EPYC 9374F, 0.6% below the AMD Ryzen 5 3600XT, and 0.7% below the Intel Core 5 120U. These deltas show that the 253PQE competes at the high end of desktop and mobile HX-class processors, while the 350 competes with mid-range desktop and mobile parts from several generations ago.
