Intel Core i3-4170 vs Intel Core i5-2500 Comparison

The Verdict

The Intel Core i5-2500 and Intel Core i3-4170 are both end-of-life desktop processors, but they serve very different purposes based on the recorded data. The i5-2500 wins 5 of 7 head-to-head benchmarks, with all of its victories in Cinebench tests, while the i3-4170 wins 2 benchmarks, both in Geekbench. The i5-2500 holds a significant advantage in multi-core workloads, beating the i3-4170 by 14.4% to 14.6% across all Cinebench multi-core tests. However, the i3-4170 dominates in single-core Geekbench performance, finishing 38.5% ahead in that specific test.

The average benchmark score tells a close story: the i5-2500 averages 1220, while the i3-4170 averages 1193, a difference of only 2.3%. Both CPUs sit in the bottom third of all processors, with the i5-2500 at the 34th percentile and the i3-4170 at the 33rd percentile. The i5-2500's nearest rivals include the Intel Core i7-3632QM (0.1% ahead) and Intel Pentium Silver N6005 (0.2% behind), while the i3-4170 sits exactly level with the AMD Athlon PRO 300U and Intel Core i7-8665UE.

For a builder choosing between these two, the decision hinges on workload type. The i5-2500 is the pick for rendering, video encoding, or any threaded productivity task, as its four physical cores consistently outperform the i3-4170's two cores with Hyper-Threading in Cinebench. The i3-4170 is the better choice for general desktop responsiveness, older games, or any application that relies heavily on single-threaded performance, where its 3.70 GHz base clock and newer Haswell architecture give it a clear edge. The i3-4170 also runs much cooler, with a 54 W TDP versus 95 W, making it easier to cool in compact builds. The i5-2500 has a launch MSRP of $117 for the i3-4170, but no launch price is recorded for the i5-2500.

Where Each One Wins

The i5-2500 wins every Cinebench test in the head-to-head comparison. In Cinebench R15 multi-core, it scores 350 versus 306, a 14.4% lead. In Cinebench R20 multi-core, it scores 1461 versus 1275, a 14.6% lead. The single-core Cinebench results also favor the i5-2500, with a 14.4% lead in R20 single-core (206 versus 180) and a 14.5% lead in R23 single-core (491 versus 429). These wins come from the i5-2500's four physical cores, which provide more raw threading capability than the i3-4170's two cores with four threads.

The i3-4170 wins both Geekbench tests, and these are not close. In Geekbench multi-core, it scores 2033 versus 1883, a 7.4% advantage. In Geekbench single-core, it scores 1090 versus 670, a massive 38.5% lead. The single-core Geekbench result is the largest delta in the entire comparison, reflecting the i3-4170's higher base clock of 3.70 GHz and the architectural improvements of Haswell over Sandy Bridge. The i3-4170 also has a notable single-core advantage in absolute terms, as its 1090 Geekbench single-core score is far above the i5-2500's 670.

For practical use, the i5-2500 is the stronger CPU for multi-threaded productivity. Video editors, 3D renderers, and users who run multiple virtual machines will see measurable gains from the two extra physical cores. The i3-4170 is the stronger CPU for single-threaded applications, which includes many older games, spreadsheet operations, and web browsing. The 38.5% single-core Geekbench gap is substantial enough to feel snappier in everyday use, despite the i5-2500's multi-core wins.

Architecture Differences

The two processors come from different Intel generations and sockets. The i5-2500 uses the Sandy Bridge architecture, built on a 32 nm process node, while the i3-4170 uses the Haswell architecture on a 22 nm process. The i5-2500 fits in Intel Socket 1155, while the i3-4170 uses Intel Socket 1150, so they are not interchangeable in a motherboard.

The core configuration is the most significant difference. The i5-2500 has 4 cores and 4 threads, with no Hyper-Threading. The i3-4170 has 2 cores and 4 threads, using Hyper-Threading to double its thread count. The i5-2500's base clock is 3.30 GHz with a boost clock of 3.70 GHz, while the i3-4170 has a base clock of 3.70 GHz with no boost clock recorded. The i3-4170's higher base clock gives it an advantage in lightly threaded workloads, but the i5-2500's extra physical cores win in fully threaded scenarios.

Cache sizes differ substantially. Both have 64 KB of L1 cache per core and 256 KB of L2 cache per core, but the shared L3 cache is 6 MB on the i5-2500 versus 3 MB on the i3-4170. The i5-2500's larger L3 cache helps with data reuse across four cores, while the i3-4170's smaller cache is sufficient for its two-core design.

The transistor counts and die sizes tell the story of the process shrink. The i5-2500 packs 1,160 million transistors on a 216 mm² die, while the i3-4170 has 1,400 million transistors on a smaller 177 mm² die. The 22 nm process allowed Intel to fit more transistors into less space, which contributes to the i3-4170's higher clock speed and better single-core efficiency.

The i3-4170 has integrated Intel HD 4400 graphics, while the i5-2500 has Intel HD 2000. The newer iGPU in the i3-4170 is more capable for basic display output and hardware acceleration. Both CPUs support DDR3 memory in dual-channel configuration, and the i3-4170 has a recorded memory bandwidth of 25.6 GB/s. Neither CPU supports ECC memory, and both have PCIe Gen 3 with 16 lanes (CPU only). The i3-4170 has a lower TDP of 54 W versus 95 W for the i5-2500, making it significantly more power-efficient. Neither processor has an unlocked multiplier.

Head-to-Head Benchmarks

The Cinebench suite shows a consistent pattern of i5-2500 superiority. In Cinebench R15 multi-core, the i5-2500 scores 350 against 306, a 14.4% margin. The R20 multi-core test shows 1461 versus 1275, also a 14.6% margin. The R23 multi-core test records 3479 versus 3038, a 14.5% lead. These are not narrow wins; the i5-2500 consistently outperforms the i3-4170 by nearly 15% in every multi-core Cinebench test.

The single-core Cinebench results are surprising given the i3-4170's higher clock speed. The i5-2500 wins Cinebench R20 single-core with 206 versus 180, a 14.4% margin. It also wins R23 single-core with 491 versus 429, a 14.5% margin. The i5-2500's larger 6 MB L3 cache and four physical cores appear to help even in single-threaded Cinebench workloads, despite the i3-4170's 3.70 GHz base clock versus 3.30 GHz.

Geekbench tells the opposite story. In Geekbench multi-core, the i3-4170 wins with 2033 versus 1883, a 7.4% advantage. In Geekbench single-core, the i3-4170 dominates with 1090 versus 670, a 38.5% lead. This is the largest performance gap in either direction across all tests. The i3-4170's Haswell architecture and higher clock speed give it a decisive edge in this workload, which likely reflects more efficient instruction handling and better single-threaded memory access patterns.

The win count favors the i5-2500 at 5 wins to 2, but the magnitude of the i3-4170's Geekbench single-core win is much larger than any single i5-2500 win. The i5-2500's wins are consistently around 14.5%, while the i3-4170's single-core win is 38.5%. This means the choice depends heavily on whether the user's applications resemble Cinebench (rendering, threaded productivity) or Geekbench (mixed workloads, single-threaded responsiveness).
