Intel Core i5-4460S vs Intel Core i5-8365UE Comparison

Head-to-Head Benchmarks

The benchmark data is remarkably consistent across every recorded workload. The Intel Core i5-8365UE wins all six head-to-head comparisons, with no victories for the Intel Core i5-4460S. The margins are tightly grouped, ranging from 15.2% to 16.1% in favor of the newer mobile chip. This uniformity suggests a fundamental performance advantage rather than workload-specific quirks.

In Cinebench R15, the i5-8365UE scores 474 in multicore against 398 for the i5-4460S, a 16% deficit for the older desktop part. The single-core test shows 66 versus 56, a 15.2% gap. Moving to Cinebench R20, the multicore result is 1978 versus 1661, again a 16% difference, while single-core lands at 279 versus 234, a 16.1% edge for the i5-8365UE.

Cinebench R23 continues the pattern. The i5-8365UE posts 4710 multicore and 665 single-core, compared to 3955 and 558 for the i5-4460S. Both deltas sit at 16% and 16.1% respectively. The Geekbench results, available only for the i5-4460S in the database, show a 2750 multicore and 1026 single-core score, but without a matching i5-8365UE Geekbench entry, no direct comparison can be drawn from that suite.

The average benchmark score reinforces the overall picture. The i5-8365UE averages 1362 across its recorded tests, placing it in the 36th percentile of all CPUs. The i5-4460S averages 1330, sitting at the 35th percentile. That one-percentile difference is small, but the head-to-head deltas tell a more decisive story: the newer chip is consistently faster by roughly 16% in every rendering workload measured.

Where Each One Wins

The i5-8365UE wins everywhere the two processors share benchmark data. There is no test in the database where the i5-4460S comes out ahead. This is not a case of one chip dominating in multithreaded tasks while the other takes single-threaded honors. The i5-8365UE leads in both categories across Cinebench R15, R20, and R23.

For users prioritizing single-threaded responsiveness, the i5-8365UE offers a meaningful edge. Its 4.10 GHz boost clock, combined with the newer Whiskey Lake architecture, delivers single-core scores that are consistently 15.2% to 16.1% higher. The i5-4460S tops out at 3.40 GHz, and that clock disadvantage shows up directly in the numbers.

In multithreaded workloads, the i5-8365UE also holds the advantage, despite its low 15 W TDP. The 8 threads versus 4 threads on the i5-4460S provide a structural benefit that the older chip cannot overcome. Every multicore test shows the same 16% gap, suggesting that the thread count advantage translates into proportional rendering performance.

The i5-4460S does have one domain where it is not beaten: power consumption is not measured in these benchmarks, but the 65 W TDP versus 15 W TDP is a specification difference, not a performance result. The data shows no workload where the desktop part wins, so the practical conclusion is that the i5-8365UE is the superior performer in all measured scenarios.

Architecture Differences

The two processors come from different eras and target different platforms. The i5-4460S is a Haswell desktop part, released in May 2014, built on Intel's 22 nm process with 1,400 million transistors and a die size of 177 mm². It uses the Intel Socket 1150 and supports DDR3 memory in a dual-channel configuration, yielding 25.6 GB/s of memory bandwidth.

The i5-8365UE is a Whiskey Lake-U mobile processor, released in April 2019, fabricated on Intel's 14 nm node. It uses the Intel BGA 1528 socket and supports DDR4 memory, also dual-channel, but with a higher 38.4 GB/s of memory bandwidth. The transistor count and die size are not recorded in the database for this part.

Both chips have 4 physical cores and share the same cache hierarchy: 64 KB of L1 per core, 256 KB of L2 per core, and 6 MB of shared L3. The critical difference is threading. The i5-4460S has 4 threads total, while the i5-8365UE has 8 threads thanks to Hyper-Threading. This doubles the logical cores and explains much of the multicore performance gap.

Clock speeds tell a similar story. The i5-4460S runs at 2.90 GHz base and 3.40 GHz boost. The i5-8365UE has a much lower base clock of 1.60 GHz, but its boost clock reaches 4.10 GHz, which is 0.70 GHz higher than the older part's maximum. The low base clock helps keep the mobile chip within its 15 W TDP, while the high boost clock allows it to surge ahead in single-threaded tasks.

Integrated graphics differ as well. The i5-4460S carries Intel HD 4600, while the i5-8365UE has UHD Graphics 620. Neither is a gaming powerhouse, but the newer iGPU is a generational step forward. Both processors support PCIe Gen 3 with 16 lanes from the CPU, and neither supports ECC memory or has an unlocked multiplier.

The production status also differs: the i5-4460S is end-of-life, while the i5-8365UE remains active. The i5-4460S launched with an MSRP of $182, and the i5-8365UE launched at $297. The market segments are distinct, with the former aimed at desktop builds and the latter at mobile devices.

The Verdict

The benchmark data leaves no ambiguity. The Intel Core i5-8365UE is the faster processor in every measured workload, with a consistent 16% advantage across Cinebench R15, R20, and R23, in both single-core and multicore tests. The 8-thread configuration and 4.10 GHz boost clock give it a clear edge over the 4-thread, 3.40 GHz i5-4460S.

Users building a desktop system with an Intel Socket 1150 motherboard and DDR3 memory already in hand might choose the i5-4460S for platform compatibility. The launch MSRP of $182 reflects its original positioning as a mainstream desktop part, and its 65 W TDP is typical for that class. But the data shows no performance scenario where it beats the newer chip.

The i5-8365UE, with its 15 W TDP and mobile BGA 1528 socket, is designed for laptops and embedded systems. Its active production status and newer Whiskey Lake architecture make it the more future-proof choice. The 38.4 GB/s memory bandwidth and DDR4 support are additional advantages over the older DDR3 platform.

For anyone choosing between these two based purely on benchmark results, the i5-8365UE is the clear winner. Its 36th percentile ranking versus 35th for the i5-4460S is a small overall difference, but the direct head-to-head results show a substantial and uniform performance lead. The i5-4460S remains a functional desktop processor, but it is outclassed in every recorded test.
