Intel Core i5-1350P vs Intel Core i9-10900 Comparison

Head-to-Head Benchmarks

The recorded data shows a clean sweep for the Intel Core i5-1350P across every shared benchmark in the head-to-head comparison. All six Cinebench tests, spanning R15, R20, and R23, favor the mobile Raptor Lake chip, though the margins are consistently narrow. The largest advantage appears in Cinebench R20 single-core, where the i5-1350P scores 979 against 961 for the i9-10900, a delta of 1.9%. Every other comparison sits at either 1.7% or 1.8%, making this a tight but unambiguous victory.

In multi-core workloads, the i5-1350P posts 16,514 in Cinebench R23 versus 16,219 for the i9-10900, a 1.8% lead. The older Comet Lake desktop part, despite its higher 65 W TDP and 20 threads, cannot overcome the newer architecture's efficiency. The same pattern holds in Cinebench R20 multi-core: 6,935 against 6,811, again a 1.8% edge. Single-core results tell an identical story. The i5-1350P reaches 2,331 in Cinebench R23 single-core, while the i9-10900 manages 2,289, a 1.8% gap that reflects the newer core design's superior per-thread performance.

Cinebench R15 results reinforce the trend. The i5-1350P scores 1,664 multi-core and 234 single-core, versus 1,634 and 230 for the i9-10900. The deltas are 1.8% and 1.7% respectively. Notably, the i9-10900 does have benchmark data outside the shared set, including Geekbench scores of 8,585 multi-core and 1,651 single-core, plus 3DMark threaded tests. The i5-1350P lacks these entries in the database, so no direct comparison is possible there. The overall average benchmark score for the i5-1350P is 4,776, placing it in the 59th percentile of all CPUs, while the i9-10900 averages 4,614 and sits at the 58th percentile. The i5-1350P's nearest rivals include the Intel Xeon W-1290E with an average score of 4,775 and a 0% delta, along with the AMD EPYC 7252 at 4,772 and a 0.1% delta. The i9-10900's closest competitor, the Intel Core i9-9900KF, scores 4,652 with a -0.8% delta, meaning the i9-10900 actually edges it out by 0.8%.

Architecture Differences

The two processors come from fundamentally different design eras. The Intel Core i5-1350P is built on Raptor Lake, specifically the Raptor Lake-P mobile variant, using a 10 nm process node. The Intel Core i9-10900 uses Comet Lake on a 14 nm node. This process gap directly explains the power and thermal characteristics: the i5-1350P has a TDP of 28 W, while the i9-10900 draws 65 W. The newer node allows the i5-1350P to deliver comparable or slightly better performance at less than half the power envelope.

Core counts differ in an interesting way. The i5-1350P has 12 cores and 16 threads, while the i9-10900 has 10 cores and 20 threads. The i9-10900 leverages Hyper-Threading across all cores, yielding 20 threads, whereas the i5-1350P uses a hybrid configuration typical of Raptor Lake, with fewer threads than cores would suggest if fully threaded. This explains why the i9-10900, despite fewer physical cores, can compete closely in multi-threaded Cinebench tests. The i5-1350P's superior single-core performance, however, compensates in the aggregate.

Cache hierarchies diverge sharply. The i5-1350P offers 80 KB L1 per core and 2 MB L2 per core, with a 12 MB shared L3. The i9-10900 has 64 KB L1 per core, 256 KB L2 per core, and a larger 20 MB shared L3. The i9-10900's bigger L3 cache is a legacy of its desktop design, but the i5-1350P's per-core L2 is substantially larger, which aids latency-sensitive workloads. The i5-1350P also supports both DDR4 and DDR5 memory, while the i9-10900 is limited to DDR4. Both use dual-channel memory buses, though the i9-10900 lists a memory bandwidth of 46.9 GB/s, a figure not recorded for the i5-1350P.

PCIe capabilities differ by generation. The i5-1350P offers Gen 4 with 20 lanes from the CPU, while the i9-10900 provides Gen 3 with 16 lanes. This gives the newer part more bandwidth and more lanes for peripherals or storage. Integrated graphics also differ: the i5-1350P uses Iris Xe Graphics with 80 execution units, whereas the i9-10900 relies on the older UHD Graphics 630. The i5-1350P's GPU is architecturally newer and designed for mobile efficiency. The i9-10900 uses Socket 1200 for desktop motherboards, while the i5-1350P uses BGA 1744, meaning it is soldered and not upgradeable. Production status also separates them: the i5-1350P is active, while the i9-10900 is end-of-life. Release dates reinforce this, with the i5-1350P launching on 2023-01-03 and the i9-10900 on 2020-04-29.

Where Each One Wins

The benchmark data indicates the i5-1350P wins every workload where both chips have shared results. That includes all Cinebench versions, both multi-core and single-core. The i5-1350P is the better choice for rendering, video encoding, and any task that scales across cores, because it achieves higher scores at lower power. Its single-core advantage also makes it stronger for lightly threaded applications like web browsing, office productivity, and older games that rely on one or two fast cores. The newer process node and larger L2 per core likely contribute to this edge, though the database does not record per-application tests beyond Cinebench.

The i9-10900, despite losing all head-to-head tests, still has virtues in the broader context. Its 20 threads give it parallel capability that the i5-1350P's 16 threads cannot match in workloads not captured by the shared benchmarks. The database shows Geekbench multi-core at 8,585 and single-core at 1,651, scores that indicate solid general-purpose performance. The i9-10900 also has 3DMark results that are absent for the i5-1350P, including a max-threads score of 8,083 and an 8-thread score of 5,276. These suggest the i9-10900 can handle gaming and moderate productivity workloads well. The i9-10900's larger 20 MB L3 cache may benefit certain data-heavy applications, though no direct benchmark in the shared set proves this.

For a desktop user with an existing Socket 1200 motherboard, the i9-10900 offers a drop-in upgrade path with no platform change. The i5-1350P, being BGA 1744, is locked to a specific mobile board. The i9-10900 also supports only DDR4, which can be an advantage if the user already owns DDR4 memory and wants to avoid upgrading to DDR5. The i5-1350P's support for both DDR4 and DDR5 gives it flexibility, but the mobile socket limits its practical use to laptops and all-in-ones.

The i9-10900 has a higher base clock (2.80 GHz vs. 1.90 GHz) and a higher boost clock (5.20 GHz vs. 4.70 GHz), yet it still loses every shared benchmark. This demonstrates that clock speed alone does not determine performance; architecture and process efficiency matter more. The i5-1350P compensates for lower clocks with newer cores and a smaller process node. The i9-10900's higher TDP of 65 W versus 28 W means it consumes more power for less performance in the tested workloads. Both processors have locked multipliers, so neither supports overclocking. Neither supports ECC memory, and both use dual-channel memory buses.

Q: Which processor supports faster PCIe?

A: The i5-1350P supports PCIe Gen 4 with 20 CPU lanes, while the i9-10900 supports PCIe Gen 3 with 16 CPU lanes. The i5-1350P's newer PCIe standard provides higher bandwidth for compatible devices.

The Verdict

The data is unambiguous: the Intel Core i5-1350P outperforms the Intel Core i9-10900 in every benchmark where both have recorded scores. The i5-1350P leads by 1.8% in Cinebench R23 multi-core and single-core, and the margins are consistent across R15 and R20. The i5-1350P accomplishes this with a 28 W TDP, a 10 nm process, and support for DDR5 memory, while the i9-10900 requires 65 W, uses a 14 nm node, and is limited to DDR4. The i5-1350P also offers PCIe Gen 4 with 20 lanes versus Gen 3 with 16 lanes, and a newer integrated GPU with 80 execution units.

The i9-10900 is not without merits. Its 20 threads and larger 20 MB L3 cache make it a capable desktop part, and its higher base and boost clocks (2.80 GHz and 5.20 GHz) suggest it can handle burst workloads well. The i9-10900 also has Geekbench and 3DMark scores that show solid general and gaming performance, though these lack direct i5-1350P comparisons. For users with an existing Socket 1200 motherboard and DDR4 memory, the i9-10900 remains a functional choice, especially given its end-of-life status means it may be available at lower prices on the secondary market.

However, the production status tells a stark story: the i5-1350P is active and current, while the i9-10900 is end-of-life. The i5-1350P's launch MSRP was $320, while the i9-10900 launched at $483. The newer part is cheaper at launch and performs better across the board. The i5-1350P's mobile socket limits its use to laptops and compact systems, but for anyone purchasing a new device, the i5-1350P is the superior choice based on recorded performance. The i9-10900 remains relevant only for those who already own a compatible desktop platform and prefer not to change motherboards. In a direct comparison, the i5-1350P wins on performance, efficiency, and platform modernity. The verdict is clear: choose the i5-1350P for new builds or mobile systems, and consider the i9-10900 only as a drop-in upgrade for legacy desktop hardware.
