Intel Core Ultra 5 245HX

Intel Core Ultra 5 245HX is an active mobile processor from Intel’s Core Ultra Series 2, built on Arrow Lake architecture at a TSMC 3 nm process. It provides 14 cores and 14 threads, a 3.10 GHz base clock, a 5.10 GHz boost clock, 24 MB of shared L3 cache, dual-channel DDR5 memory with 102.4 GB/s bandwidth, and integrated Arc Xe-LPG Graphics with 48 EUs. Its average benchmark score of 9,849 places it in the 70th percentile of all CPUs, and the nearest-rival data shows a highly concentrated group around that score.

Single-Thread vs Multi-Thread Behavior

The Cinebench results create a clear separation between single-thread and multi-thread behavior. In Cinebench R23, the processor scores 4,807 in single-core and 34,050 in multi-core. The Cinebench R20 results follow the same shape: 2,018 single-core and 14,301 multi-core. Cinebench R15 shows 484 single-core and 3,432 multi-core. Across all three versions of the test, the multi-core figure is much larger than the single-core figure, which is the expected outcome for a 14-core design.

The thread configuration matters here. The processor has 14 threads, matching its 14 cores exactly, so the multi-core result is produced by physical cores rather than extra logical threads. That makes the multi-core scores a direct measure of how much throughput the 14 cores can sustain when the workload scales across the entire chip. The single-core scores, in contrast, are the measure of a lightly threaded workload that cannot spread out. The 5.10 GHz boost clock is the specification most relevant to those short, single-thread bursts, while the 3.10 GHz base clock describes the lower sustained frequency floor for all-core loads.

For real workloads, the split is easy to interpret. A task that is built to use many threads will be drawn to the multi-core result, such as the 34,050 R23 score or the 14,301 R20 score. A task that depends on one thread will be better represented by the single-core numbers, such as the 4,807 R23 result. The difference between those numbers is not an artifact of the benchmark; it is the difference between throughput and latency-sensitive responsiveness.

Who Should Consider It

The 70th percentile placement means the 245HX sits above most CPUs in the database, and the multi-core Cinebench scores indicate that it is a strong candidate for creation workloads that can use all 14 cores. Rendering, code compilation, and other parallel tasks will see the benefit of the 34,050 R23 multi-core score. The R20 multi-core score of 14,301 and the R15 multi-core score of 3,432 reinforce the same conclusion: this is a processor with substantial all-core throughput.

Office productivity is a different workload case. Typical office tasks rarely use all 14 cores, so the single-core R23 score of 4,807 and the 5.10 GHz boost become more relevant. Those numbers suggest good responsiveness for a mobile processor, particularly in a BGA 2114 laptop platform. For users whose work alternates between light single-threaded tasks and heavier parallel jobs, the processor covers both sides with the same silicon.

Gaming workloads sit somewhat between these cases. CPU-bound game logic tends to favor high single-thread performance, and the 4,807 single-core R23 score and 5.10 GHz boost clock are the relevant figures there. The integrated Arc Xe-LPG Graphics with 48 EUs provides a built-in display path, so the processor can be used in a laptop without a discrete GPU. The 55 W TDP class also signals that this is not an ultra-low-power part; it belongs in a performance-oriented mobile chassis rather than a fanless or minimalist portable design.

Benchmark Performance

The benchmark profile is consistent across Cinebench versions. In R15, the processor posts 484 single-core and 3,432 multi-core. In R20, it posts 2,018 single-core and 14,301 multi-core. In R23, it posts 4,807 single-core and 34,050 multi-core. The multi-core results are consistently much higher than the single-core results, showing that the 14-core cluster is the dominant asset of this processor.

The average benchmark score of 9,849 is the aggregate reference point. Against its nearest rivals, the deltas are small. The 245HX is 0.6% higher than the Intel Core i7-1165G7’s average score of 9,787. It is 1.6% higher than the Intel Core i5-1035G1’s 9,691. It is 2.4% higher than the Intel Core i5-1135G7’s 9,620. The only rival ahead is the AMD EPYC 7F52, which averages 10,159, putting the 245HX 3% behind. These margins are narrow enough that the 245HX is not a runaway winner in its immediate peer group.

The placement of the 9,849 average score is notable because the entire rival set is tightly packed. The EPYC 7F52 sits at 10,159 on the high end, while the Core i5-1135G7 sits at 9,620 on the low end. That gives the 245HX a position near the middle of a dense field, rather than at the edge. In the broader database, the 70th percentile rank shows it still outperforms a clear majority of all CPUs, even though the nearest rivals are very close in aggregate terms.

How It Compares

AMD EPYC 7F52 — This is the only nearest rival with a higher average score. The EPYC 7F52 posts 10,159, and the 245HX is 3% behind. It is a narrow gap, but it is the one comparison in which the 245HX trails the rival box in aggregate performance.

Intel Core i7-1165G7 — The Core i7-1165G7 has an average score of 9,787. The 245HX is only 0.6% higher, which makes this the closest comparison in the rival set. In practical aggregate terms, this is essentially a tie.

Intel Core i5-1035G1 — The Core i5-1035G1 averages 9,691. The 245HX is 1.6% higher. This is a slightly larger advantage than the gap to the Core i7-1165G7, but it is still a modest separation in the benchmark data.

Intel Core i5-1135G7 — The Core i5-1135G7 has the lowest average score in the nearest-rival group at 9,620. The 245HX is 2.4% higher, which is the largest lead the 245HX holds against any of the four listed rivals. Even so, the edge is small enough that the group as a whole remains close.

Power and Thermals

The thermal design power is 55 W. That TDP places the 245HX in a high-performance mobile class, not an ultraportable processor class. A BGA 2114 laptop platform built around this processor needs a cooling solution capable of handling sustained loads across 14 cores. The 5.10 GHz boost clock will raise heat output during short bursts, while the 3.10 GHz base clock defines the thermal load during more sustained all-core work.

The multiplier is unlocked, which adds another thermal variable. If the platform exposes overclocking controls, the user can increase clock ratios above the standard 5.10 GHz boost, and that will push thermal demand higher than the 55 W TDP baseline. The integrated Arc Xe-LPG Graphics with 48 EUs also occupies the same package, so any graphics load contributes to the total heat generated by the chip.

The manufacturing details give some context for the thermal profile. The die is produced on a TSMC 3 nm process and contains 17,800 million transistors on a 243 mm² die. Those are dense, modern figures, and they indicate a processor designed to deliver high frequencies and a wide core count in a mobile package. The 55 W TDP is the main practical takeaway: this is a processor that belongs in a performance laptop or creator-oriented system with active cooling, not a low-power chassis.
