Q: Are these CPUs comparable in overall benchmark averages?

A: Nearly identical. The i7-10510Y has an average benchmark score of 1092, and the i5-3350P averages 1088. Both sit at the 30th percentile among all CPUs. The i7-10510Y's nearest rival is the Intel Core i7-4600M (deltaPct -0.1%), while the i5-3350P's closest match is the AMD Athlon 220GE (deltaPct 0%).

Q: Which CPU has more threads?

A: The i7-10510Y has 8 threads from 4 cores, while the i5-3350P has 4 threads from 4 cores. Despite the i7-10510Y's Hyper-Threading advantage, the i5-3350P still wins all multi-core benchmarks, indicating that its higher base clock (3.10 GHz versus 1.20 GHz) more than compensates.

Architecture Differences

The two processors come from different Intel eras and design philosophies. The i7-10510Y is built on the Comet Lake architecture with a 14 nm process node, while the i5-3350P uses the older Ivy Bridge architecture on a 22 nm node. The process node difference is significant: 14 nm versus 22 nm means the i7-10510Y packs more transistors per area, though the i5-3350P's die size is listed at 133 mm² while the i7-10510Y's die size is not provided.

Clock speeds show a stark contrast. The i7-10510Y runs at a 1200 MHz base clock but boosts to 4500 MHz, a 3.3 GHz range that suggests aggressive burst behavior. The i5-3350P has a 3100 MHz base and 3300 MHz boost, a much narrower 200 MHz range. This explains why the i5-3350P wins sustained workloads: it starts at 3.1 GHz and never drops far, while the i7-10510Y must ramp from 1.2 GHz and may not sustain peak boost under all-core loads.

Cache configurations differ in total L3 capacity. The i7-10510Y has 8 MB of shared L3 cache, while the i5-3350P has 6 MB shared L3. Both have identical L1 (64 KB per core) and L2 (256 KB per core) configurations. The i7-10510Y's larger L3 cache compensates for its lower base clock, but the benchmark results show it is not enough to overcome the i5-3350P's clock advantage.

The i7-10510Y includes integrated UHD Graphics, whereas the i5-3350P has no integrated graphics listed. This makes the i7-10510Y a more complete mobile solution, but the i5-3350P's lack of iGPU is typical for the "P" suffix desktop parts. Memory support is DDR3 for both, though the i5-3350P specifies dual-channel memory bus while the i7-10510Y does not list a memory bus configuration.

Head-to-Head Benchmarks

The data shows a consistent pattern: the i5-3350P wins every test, with all deltas clustering tightly between -13.8% and -14%. In Cinebench R15 multi-core, the i5-3350P scores 371 against the i7-10510Y's 319, a 14% deficit for the i7. This is the largest percentage gap in the dataset.

Cinebench R20 multi-core repeats the trend with the i5-3350P at 1546 and the i7-10510Y at 1332, a 13.8% difference. The R20 single-core test shows 217 for the i5-3350P versus 187 for the i7-10510Y, again a 13.8% margin. These consistent percentages suggest a fixed performance ratio rather than workload-specific behavior.

The most comprehensive test, Cinebench R23 multi-core, gives the i5-3350P 3681 points versus 3173 for the i7-10510Y. The single-core R23 test shows 519 versus 447, a 13.9% gap. Interestingly, the i5-3350P's Geekbench scores (1730 multi-core, 584 single-core) have no counterpart in the i7-10510Y's benchmark list, so no head-to-head comparison is possible there.

The i5-3350P's wins are not marginal; they are consistently around 14% across every test. This uniformity indicates a fundamental throughput advantage rather than a specific workload optimization. The i7-10510Y's 8 threads do not help it close the gap, and its higher boost clock of 4.5 GHz is evidently not sustained in these Cinebench runs.

Specification Differences

The specifications diverge substantially across nearly every field. The i7-10510Y offers 4 cores and 8 threads, while the i5-3350P provides 4 cores and 4 threads. Base clocks differ by 1900 MHz (1200 MHz versus 3100 MHz), and boost clocks differ by 1200 MHz (4500 MHz versus 3300 MHz). The i7-10510Y's TDP is 9 watts, a 60-watt reduction from the i5-3350P's 69 watts.

Sockets are incompatible: the i7-10510Y uses Intel BGA 1440, and the i5-3350P uses Intel Socket 1155. The i7-10510Y is from Core 10th Gen (Comet Lake-Y, marketed as Core i7 Comet Lake-Y), while the i5-3350P is from the earlier Core i5 Ivy Bridge generation. Process nodes differ at 14 nm versus 22 nm, and the i5-3350P lists a die size of 133 mm² with part number SR0WS, while the i7-10510Y has no die size or part number listed.

Cache totals differ: 8 MB shared L3 for the i7-10510Y versus 6 MB shared L3 for the i5-3350P. The i7-10510Y includes UHD Graphics, while the i5-3350P has no integrated graphics. Memory support is DDR3 for both, but the i5-3350P specifies dual-channel memory bus and PCIe Gen 3 with 16 lanes (CPU only), while the i7-10510Y lists neither memory bus nor PCIe details. The i7-10510Y is marked as Active in production and released on 2019-08-20, while the i5-3350P's production status is not listed and its release date is 2012-09-02. Neither chip has a launch MSRP listed.

The Verdict

The data points to one-sided conclusion: the i5-3350P is the better performer in every benchmarked workload. Its 13.8-14% lead across all Cinebench tests, including single-core, shows that raw clock speed and architectural efficiency trump the i7-10510Y's thread count and newer process node. The i7-10510Y's only advantages are power efficiency (9W TDP versus 69W) and integrated graphics, neither of which appear in benchmark scores.

For desktop users who prioritize compute performance, the i5-3350P is the clear choice. Its 3681 Cinebench R23 multi-core score and 519 single-core score are meaningfully higher than the i7-10510Y's 3173 and 447. However, the i7-10510Y's 9W TDP makes it suitable for fanless or ultra-low-power mobile designs where the i5-3350P's 69W TDP would be impractical. The i7-10510Y's UHD Graphics also provides display output capability that the i5-3350P lacks entirely.

Neither chip distinguishes itself in the broader market: both sit at the 30th percentile of all CPUs, and their average scores (1092 versus 1088) are separated by less than 0.4%. The i7-10510Y's nearest rivals include the Intel Core i7-4600M (deltaPct -0.1%) and Intel Core i5-3475S (deltaPct 0.1%), while the i5-3350P's rivals include the AMD Athlon 220GE (deltaPct 0%) and Intel Core i5-2450P (deltaPct 0.2%). These proximity scores indicate both processors are mid-pack offerings.

Where Each One Wins

The i5-3350P wins in every scenario that involves sustained CPU computation. Its 3.1 GHz base clock delivers consistent throughput in multi-threaded workloads like Cinebench R23 multi-core (3681 versus 3173), and its single-core advantage (519 versus 447) makes it better for lightly-threaded applications. Desktop users with standard cooling solutions can handle its 69W TDP, and its PCIe Gen 3 with 16 lanes provides connectivity for discrete graphics.

The i7-10510Y wins in power-constrained mobile environments. Its 9W TDP is a fraction of the i5-3350P's 69W, enabling thin-and-light laptops with passive or minimal cooling. The integrated UHD Graphics means no discrete GPU is required for basic display output, and its 4.5 GHz boost clock offers short bursts of high performance when needed. Its 8 threads from 4 cores provide better multitasking headroom than the i5-3350P's 4 threads, even if the benchmarks show it loses sustained workloads.

For workloads that fit within short boost windows, the i7-10510Y's 4500 MHz maximum boost could provide snappy responsiveness in single-threaded tasks, but the Cinebench R23 single-core score (447 versus 519) shows that even this advantage does not materialize in practice. The i5-3350P's steady 3.3 GHz boost appears to be more effective than the i7-10510Y's higher but less sustainable 4.5 GHz peak. In summary, the i5-3350P is the pick for raw performance, while the i7-10510Y is the pick for mobility and power efficiency.
