Intel Core i5-2500T vs Intel Core i7-4500U Comparison

The Intel Core i7-4500U and Intel Core i5-2500T are separated by more than just their generation gap; the data shows a clear, consistent performance hierarchy. Across every shared benchmark, the older desktop i5-2500T decisively outperforms the newer mobile i7-4500U, winning all five head-to-head tests. Despite the i7-4500U carrying a higher tier name, its low-power mobile design places it firmly behind the i5-2500T in raw compute throughput, with the average benchmark scores nearly identical (859 vs. 856) but the distribution of wins heavily favoring the desktop chip.

Head-to-Head Benchmarks

The most striking pattern is the uniformity of the i5-2500T’s victory margin. In Cinebench R15 multicore, the i5-2500T scores 250 against the i7-4500U’s 212, a 15.2% advantage. This gap barely moves in Cinebench R20 multicore, where the i5-2500T posts 1045 versus 887, a 15.1% lead. The consistency suggests this is not a workload-specific quirk but a fundamental throughput difference driven by core count and clock speed.

Single-core performance tells the same story. In Cinebench R20 single-core, the i5-2500T leads with 147 points against 125, a 15% advantage. The Cinebench R23 single-core test shows the i5-2500T at 351 versus 298, again a 15.1% delta. The i5-2500T’s higher base clock of 2.30 GHz and boost clock of 3.30 GHz, compared to the i7-4500U’s 1.80 GHz base and 3.00 GHz boost, directly explain this single-core edge. The i7-4500U cannot compensate for its lower clocks even with its newer Haswell architecture.

Multicore results amplify the single-core trend. The i5-2500T’s four physical cores, each running at higher clocks, simply outmuscle the i7-4500U’s two cores with Hyper-Threading. In Cinebench R23 multicore, the i5-2500T reaches 2489 while the i7-4500U manages 2113, a 15.1% difference. This is a notable result because the i7-4500U’s four threads do help it close some of the gap, but not enough to overcome the i5-2500T’s additional physical cores and superior frequency. The data shows a clear verdict: the i5-2500T wins every test by roughly 15%, with no single benchmark where the i7-4500U takes the lead.

FAQ

Q: Which processor has a higher average benchmark score?

A: The Intel Core i7-4500U has an average benchmark score of 859, while the Intel Core i5-2500T scores 856. The difference is a negligible 0.3% in favor of the i7-4500U, placing them virtually tied in aggregate performance.

Q: How does the i7-4500U compare to the i5-2500T in Cinebench R23 multicore?

A: The i5-2500T scores 2489, which is 15.1% higher than the i7-4500U’s 2113. This represents the largest absolute gap between the two in the tested workloads.

Q: Does the i7-4500U win any head-to-head benchmark?

A: No. The head-to-head data shows the i5-2500T winning all five shared tests, with a win count of 5 for the i5-2500T and 0 for the i7-4500U.

Q: What is the difference in core and thread counts?

A: The i5-2500T has 4 cores and 4 threads, while the i7-4500U has 2 cores and 4 threads. The i5-2500T’s extra physical cores are a primary factor in its multicore lead.

Q: How do their clock speeds compare?

A: The i5-2500T has a base clock of 2.30 GHz and a boost clock of 3.30 GHz. The i7-4500U has a base clock of 1.80 GHz and a boost clock of 3.00 GHz, making the i5-2500T faster in both metrics.

Q: Which processor has a larger L3 cache?

A: The i5-2500T has 6 MB of shared L3 cache, while the i7-4500U has 4 MB of shared L3 cache. This 2 MB difference contributes to the i5-2500T’s performance advantage in cache-sensitive workloads.

Architecture Differences

The two chips come from different architectural eras and design philosophies. The i7-4500U is built on the Haswell architecture using a 22 nm process node, with 1,300 million transistors on a 118 mm² die. In contrast, the i5-2500T uses the older Sandy Bridge architecture on a 32 nm process, packing 1,160 million transistors into a much larger 216 mm² die. The newer 22 nm process gives the i7-4500U a transistor density advantage, but the i5-2500T’s larger physical die allows for more cores and cache.

The cache hierarchy shows a clear divergence. Both chips share the same per-core L1 (64 KB) and L2 (256 KB) configuration, but the shared L3 cache differs: the i7-4500U offers 4 MB, while the i5-2500T offers 6 MB. This 50% larger L3 cache on the i5-2500T is a significant architectural advantage for workloads that benefit from larger pools of fast memory.

The i7-4500U is a mobile part with a 15 W TDP, while the i5-2500T is a desktop part rated at 45 W TDP. This 30 W TDP difference explains why the i7-4500U runs at lower clock speeds despite its architectural advantages. The i7-4500U also uses a different socket (Intel BGA 1168) compared to the i5-2500T’s Intel Socket 1155, reflecting their different market segments. The i7-4500U features Intel HD 4400 integrated graphics, whereas the i5-2500T comes with Intel HD 2000. Neither chip supports ECC memory, and both accept DDR3 memory, though the i5-2500T explicitly supports dual-channel memory while the i7-4500U’s memory bus is unspecified.

The Verdict

The benchmark data is unambiguous: the Intel Core i5-2500T is the faster processor in every tested workload. It wins all five head-to-head benchmarks with a consistent margin of approximately 15%, driven by its higher clock speeds and two additional physical cores. Anyone looking for raw compute performance, whether single-core or multi-core, should choose the i5-2500T based strictly on this data.

The i7-4500U’s only statistical advantage is a 0.3% higher average benchmark score (859 vs. 856), which is within the margin of error and does not translate into a single head-to-head win. This suggests that the i7-4500U’s newer Haswell architecture and lower power draw do not overcome the i5-2500T’s brute-force advantages in core count and frequency. The i5-2500T is the clear winner for any application where absolute CPU performance is the primary criterion.

Specification Differences

The two processors differ across nearly every major specification category. The i5-2500T has 4 cores and 4 threads, while the i7-4500U has 2 cores and 4 threads. The i5-2500T’s base clock is 2.30 GHz versus 1.80 GHz for the i7-4500U, and its boost clock is 3.30 GHz versus 3.00 GHz. The TDP difference is substantial: 45 W for the i5-2500T versus 15 W for the i7-4500U.

Architecturally, the i5-2500T uses Sandy Bridge on a 32 nm node, while the i7-4500U uses Haswell on a 22 nm node. The transistor count is 1,160 million for the i5-2500T and 1,300 million for the i7-4500U. Die size is 216 mm² for the i5-2500T and 118 mm² for the i7-4500U. The L3 cache is 6 MB on the i5-2500T and 4 MB on the i7-4500U.

The i5-2500T uses Intel Socket 1155 and is a desktop part, while the i7-4500U uses Intel BGA 1168 and is a mobile part. The i5-2500T has PCIe Gen 3 with 16 lanes (CPU only), while the i7-4500U has no PCIe specification listed. Integrated graphics differ: Intel HD 2000 on the i5-2500T versus Intel HD 4400 on the i7-4500U. The i5-2500T is marked as end-of-life production status, while the i7-4500U has no production status listed. Neither chip supports ECC memory, and both support DDR3, but only the i5-2500T specifies dual-channel memory support.

Where Each One Wins

The i5-2500T wins every performance-based category. Its 15% lead in Cinebench R15, R20, and R23 multicore tests makes it the better choice for multi-threaded workloads like video rendering, 3D modeling, and batch processing. Its 15% single-core advantage in Cinebench R20 and R23 makes it superior for lightly-threaded applications such as older games, office productivity, and web browsing. The larger 6 MB L3 cache and higher clock speeds support both single-threaded responsiveness and multi-threaded throughput.

The i7-4500U wins in efficiency and platform characteristics. Its 15 W TDP is one-third of the i5-2500T’s 45 W TDP, making it suitable for fanless or ultra-portable designs where power draw is critical. The newer 22 nm Haswell architecture and transistor count of 1,300 million suggest better instruction-per-clock efficiency, though the benchmark data shows this does not translate into a performance win. The i7-4500U’s Intel HD 4400 graphics are a newer generation than the i5-2500T’s Intel HD 2000, potentially offering better iGPU performance, though no iGPU benchmarks are provided in the data.

The i7-4500U also has a later release date (2013-06-03) compared to the i5-2500T (2011-01-08), meaning it is a newer design with potentially better driver support and software optimizations. However, for pure CPU performance, the i5-2500T is the definitive winner. The i7-4500U should only be chosen when its mobile form factor and low power consumption are more important than raw computational speed.
