Intel Core i5-1335UE

The Intel Core i5-1335UE is a Raptor Lake-U mobile processor from Intel, manufactured on the company's 10 nm process. It pairs 10 cores and 12 threads with a 1.30 GHz base clock, a 4.50 GHz boost clock, and a 15 W TDP, and it is soldered to the Intel BGA 1744 socket rather than dropped into a user-replaceable socket. The chip supports DDR4 and DDR5 memory in dual-channel mode with ECC disabled, exposes 8 PCIe Gen 4 lanes from the CPU, and carries the Iris Xe Graphics 80EU integrated GPU. It launched on January 3, 2023, remains in active production, and has a locked multiplier. In the benchmark database it holds the 52nd percentile among all CPUs, with an average benchmark score of 2670.

Benchmark Performance

The average benchmark score of 2670 places the i5-1335UE just past the midpoint of the tested CPU population. That position is remarkably crowded. Its four nearest rivals all sit within a 0.6% band of its score: the Intel Core i5-9500F averages 2674, the Intel Core 3 N355 averages 2684, the AMD Ryzen 3 7330U averages 2685, and the Intel Xeon E5-4650 v3 averages 2664. Against those, the i5-1335UE trails the Core i5-9500F by 0.1%, the Core 3 N355 by 0.5%, and the Ryzen 3 7330U by 0.6%, while leading the Xeon E5-4650 v3 by 0.2%. None of those margins is large enough to matter in practice. Benchmark results indicate a 15 W mobile chip trading blows with parts that, on paper, come from very different product families.

Cinebench results reinforce the picture. In Cinebench R23, the i5-1335UE scores 9233 points multi-core and 1303 points single-core. In Cinebench R20, the figures are 3877 multi-core and 547 single-core. In Cinebench R15, they are 930 multi-core and 131 single-core. All three Cinebench versions tell the same story: the chip leans on its core count for throughput while the 4.50 GHz boost clock keeps single-thread results competitive. The 52nd percentile placement is consistent with those scores — a hair above the database average rather than a standout. For a 15 W processor, this is a solid middle-of-the-pack showing, but buyers should not expect it to punch far above its weight against higher-power parts.

Power and Thermals

The 15 W TDP is the defining constraint of this processor. A chip in this power class does not need a large tower cooler or aggressive liquid cooling; the kind of low-profile heatsink and modest fan found in thin-and-light notebooks is the intended fit. The 10 nm process helps keep thermal load modest, and because the i5-1335UE is soldered to the BGA 1744 socket, the cooling solution is whatever the laptop vendor installs. There is no aftermarket cooler path and no upgrade path — what is soldered down is what you keep.

The locked multiplier removes overclocking from the equation. Enthusiasts cannot push the 4.50 GHz boost clock any higher, so power and thermal behavior stays within the vendor's design envelope. Memory support adds flexibility: DDR4 or DDR5, both dual-channel, with ECC not supported. The PCIe Gen 4 interface provides 8 lanes from the CPU, which is appropriate for this class of machine. With a January 3, 2023 launch date and active production status, the i5-1335UE is a current shipping part, and its power class is aimed squarely at battery-conscious mobile designs. In practice, a 15 W chip should be comfortable in a slim chassis with minimal cooling noise under light loads.

Single-Thread vs Multi-Thread Behavior

The split between single-thread and multi-thread performance is well defined. Single-core results are 131 in Cinebench R15, 547 in R20, and 1303 in R23. Multi-core results are 930 in R15, 3877 in R20, and 9233 in R23. The multi-core figures are much larger, as expected from a 10-core, 12-thread configuration. The wide operating range between the 1.30 GHz base clock and the 4.50 GHz boost clock reflects a chip that can idle near its base when lightly loaded and sprint when a single thread needs attention.

For bursty workloads — launching applications, rendering web pages, recalculating spreadsheets — the single-core scores and the high boost clock matter most. The i5-1335UE will feel responsive in everyday office use. For sustained workloads that engage all cores, such as video encoding, code compilation, or batch image processing, the multi-core scores are what count, and 9233 in Cinebench R23 is a respectable result for the power class. The 15 W envelope does impose a limit: sustained all-core loads will draw against the same power budget that the boost clock uses, so the chip is better at short bursts of heavy work than at marathon rendering sessions. Users who need constant all-core throughput should look at higher-TDP parts; users who need occasional bursts will find the behavior well matched to mobile use.

How It Compares

Intel Core i5-9500F — This rival averages 2674, with the i5-1335UE trailing by 0.1%. That is a statistical dead heat; a 0.1% gap is smaller than typical run-to-run variance in any benchmark suite. Users coming from a system built around the i5-9500F would see no aggregate throughput difference in this data.

Intel Xeon E5-4650 v3 — The Xeon averages 2664, with the i5-1335UE ahead by 0.2%. Once again the delta is negligible. The comparison is notable because a low-power mobile chip from 2023 lands effectively level with a server-oriented part, at least in the aggregate benchmark score used here.

Intel Core 3 N355 — The N355 averages 2684, putting the i5-1335UE 0.5% behind. This is the closest competitor from Intel's current low-power lineup in the data. The gap is still within noise, and the two parts occupy a similar performance class.

AMD Ryzen 3 7330U — This rival averages 2685, the highest of the four, and the i5-1335UE trails by 0.6%. That is the largest delta among the nearest rivals and still a negligible one. Across all four comparisons, the i5-1335UE's 2670 sits in a tight cluster; the choice between these parts should be decided on factors other than raw aggregate throughput, because benchmark results indicate they are effectively equivalent.

Who Should Consider It

For anyone assembling or selecting a thin-and-light mobile system, the i5-1335UE sits in a sensible spot. The 15 W TDP makes it appropriate for battery-conscious notebooks, while the 10-core, 12-thread configuration and Cinebench R23 multi-core score of 9233 give it enough throughput for mainstream productivity and occasional creative work. Office users who spend their day in documents, browsers, and communication tools will benefit from the 4.50 GHz boost clock and single-core R23 score of 1303; these are precisely the bursty, lightly threaded workloads the chip handles best.

Content creators working on the move — light video encoding, batch photo processing, or code compilation — will find the multi-core results useful, though sustained all-core loads will be limited by the 15 W power envelope. Gamers should keep expectations low: the only graphics option is the Iris Xe Graphics 80EU integrated GPU, which is not a high-performance part, so demanding games are not the target use case. Users who want overclocking or a socketed, upgradable CPU should look elsewhere — this part is soldered and multiplier-locked. For those comparing it against the Ryzen 3 7330U, Core 3 N355, Core i5-9500F, or Xeon E5-4650 v3, the benchmark data says the aggregate scores are within 0.6%, so the decision should come down to platform fit and system design rather than raw performance. The i5-1335UE is a capable, unremarkable, and thoroughly mainstream mobile processor.
