Intel Core i3-4370 vs Intel Core i5-3570T Comparison

The Intel Core i5-3570T and Intel Core i3-4370 are separated by less than half a percent in nearly every benchmark, making this one of the closest head-to-head matchups in the database. The i5-3570T wins all five comparative tests, but the margins are razor-thin, ranging from 0.3% to 0.5%. The data indicates that the two processors are effectively performance equals in the workloads tested, with the i5-3570T holding a nominal but consistent edge.

Head-to-Head Benchmarks

The i5-3570T’s largest victory comes in the Cinebench R20 single-core test, where it scores 195 against the i3-4370’s 194, a delta of 0.5%. This is the only test where the margin exceeds 0.4%. In Cinebench R23 single-core, the i5-3570T posts 465 versus 463 for the i3-4370, a 0.4% advantage. The remaining three tests all show a 0.3% lead for the i5-3570T: Cinebench R15 multicore (331 vs 330), Cinebench R20 multicore (1383 vs 1379), and Cinebench R23 multicore (3293 vs 3284).

The average benchmark scores tell the same story. The i5-3570T averages 1136, while the i3-4370 averages 1130, a difference of just 0.5%. Both processors sit at the 32nd percentile of all CPUs, meaning they occupy the same performance tier. The i5-3570T’s nearest rivals include the Intel Core i5-2550K at 1136 (0% delta) and the Intel Xeon E5640 at 1137 (-0.1%), while the i3-4370’s closest competitor is the Intel Pentium Gold G5500 at 1130 (0% delta) and the Intel Core i5-4690T at 1129 (0.1% delta). These rival groupings reinforce that both chips land in a crowded mid-pack of desktop processors.

Interpreting the numbers: the i5-3570T’s win count of 5 to 0 is mathematically decisive, but the practical significance is negligible. A 0.3% difference in Cinebench R15 multicore (331 vs 330 points) is well within run-to-run variation. The consistent direction of the wins, however, suggests the i5-3570T has a slight structural advantage, likely from its four physical cores versus the i3-4370’s two cores with Hyper-Threading. In single-threaded tests, the i3-4370’s much higher base clock of 3.80 GHz nearly offsets the i5-3570T’s boost clock of 3.30 GHz, but not quite.

Where Each One Wins

The i5-3570T wins every benchmark in this comparison, but the reasons differ by workload type. In multi-core tests, the i5-3570T’s four physical cores provide a small edge over the i3-4370’s two cores and four threads. Cinebench R23 multicore shows the i5-3570T at 3293 versus 3284, a 0.3% lead. The i3-4370, with only two physical cores, relies on Hyper-Threading to reach similar scores, but the i5-3570T’s additional physical cores give it a slight throughput advantage in heavily threaded rendering workloads.

For single-core performance, the i3-4370 fights back with its 3.80 GHz base clock, which is 1.50 GHz higher than the i5-3570T’s 2.30 GHz base clock. Yet the i5-3570T still wins single-core tests. In Cinebench R23 single-core, the i5-3570T scores 465 versus 463, and in Cinebench R20 single-core, it scores 195 versus 194. The i3-4370 has no boost clock listed, so it runs at a fixed 3.80 GHz, while the i5-3570T boosts to 3.30 GHz. Despite the i3-4370’s higher sustained clock, the i5-3570T’s Ivy Bridge architecture edges it out in these single-threaded tests.

Use-case split: for multi-threaded rendering and video encoding, the i5-3570T is the safer pick based on its four cores and consistent multicore wins. For single-threaded workloads, the i3-4370 is closer, but the data still favors the i5-3570T. Neither chip has a meaningful advantage in any tested scenario; the largest delta is 0.5%. The i5-3570T wins across the board, but the i3-4370’s higher clock speed keeps it within striking distance in every test.

Architecture Differences

Both processors are built on Intel’s 22 nm process node with 1,400 million transistors, but they use different architectures. The i5-3570T is based on Ivy Bridge, while the i3-4370 uses Haswell. The die size differs: the i5-3570T measures 160 mm², while the i3-4370 is larger at 177 mm². This die size difference reflects architectural changes between the generations, even though the transistor count is identical.

Core and thread counts differ significantly. The i5-3570T has 4 cores and 4 threads, with no Hyper-Threading. The i3-4370 has 2 cores and 4 threads, using Hyper-Threading to double its thread count. Cache configurations also differ: both have 64 KB L1 cache per core and 256 KB L2 cache per core, but the L3 cache is 6 MB shared on the i5-3570T versus 4 MB shared on the i3-4370. The i5-3570T’s larger L3 cache gives it more room for shared data, which likely contributes to its slight multicore edge.

Clock speeds are a major differentiator. The i5-3570T has a base clock of 2.30 GHz and a boost clock of 3.30 GHz. The i3-4370 has a base clock of 3.80 GHz and no boost clock, meaning it runs at a fixed frequency. The i3-4370’s base clock is 1.50 GHz higher than the i5-3570T’s base, but the i5-3570T’s boost clock closes that gap to 0.50 GHz.

Thermal design power favors the i5-3570T at 45W versus 54W for the i3-4370. Both use the same DDR3 memory support with dual-channel memory buses. The integrated graphics differ: the i5-3570T has Intel HD 2500, while the i3-4370 has Intel HD 4600. The i3-4370’s newer Haswell GPU is a clear upgrade. PCIe support is Gen 3 for both, but the i5-3570T specifies 16 lanes (CPU only) while the i3-4370 simply lists Gen 3. Sockets differ, with the i5-3570T on Intel Socket 1155 and the i3-4370 on Intel Socket 1150.

The Verdict

The data points to a clear but marginal winner: the Intel Core i5-3570T. It wins all five head-to-head benchmarks, holds a higher average benchmark score (1136 vs 1130), and does so with a lower TDP of 45W versus 54W. The i5-3570T’s four physical cores and 6 MB L3 cache give it a structural advantage in multi-threaded workloads, while its single-core performance edges out the i3-4370 despite the latter’s higher 3.80 GHz base clock.

The i3-4370 is not without justification. Its 3.80 GHz fixed clock makes it competitive in single-threaded tasks, coming within 0.5% of the i5-3570T in Cinebench R20 single-core. The i3-4370 also has a superior integrated GPU (Intel HD 4600 vs HD 2500) and a larger die size of 177 mm² versus 160 mm². For users who need better integrated graphics without a discrete card, the i3-4370 is the better choice.

However, the benchmark results are emphatic: the i5-3570T wins every test, even if the margins are tiny. The 0.3% to 0.5% deltas are unlikely to translate into perceptible real-world differences, but the i5-3570T’s additional cores and larger cache make it the more future-proof option for multi-threaded software. The i3-4370’s only meaningful wins are in features, not performance: better iGPU and a newer Haswell architecture. For pure CPU performance, the i5-3570T is the victor.
