Intel Core i5-3570S vs Intel Core i5-4440 Comparison

Head-to-Head Benchmarks

The benchmark data shows a consistent, if narrow, victory for the Intel Core i5-4440 across every Cinebench workload tested. In the six head-to-head comparisons, the i5-4440 wins all of them, with deltas ranging from 1.8% to 2.2%. This is not a dramatic performance gap, but it is uniform: there is no single test where the i5-3570S manages to pull ahead.

The largest relative margin comes in Cinebench R23 multicore, where the i5-4440 scores 4077 against 3991 for the i5-3570S, a 2.2% advantage. The smallest margin is in Cinebench R15 single-core, where the i5-4440 scores 57 versus 56, a 1.8% difference. In between, Cinebench R20 multicore shows 1712 versus 1676 (2.1%), R20 single-core shows 241 versus 236 (2.1%), and R15 multicore shows 410 versus 402 (2.0%). The R23 single-core test also lands at 2.1%, with 575 versus 563.

What is notable is the consistency of the gap. Across different Cinebench versions, which vary in workload intensity and threading patterns, the i5-4440 maintains roughly the same 2% lead. This suggests the advantage is not workload-specific but rather a general characteristic of the processor's performance profile. The i5-3570S does post a Geekbench score, with 1793 multicore and 632 single-core, but no comparable Geekbench data exists for the i5-4440 in this dataset, so that comparison cannot be made here.

Looking at the broader benchmark averages, the i5-4440 has an average score of 1179 across all its tested benchmarks, while the i5-3570S averages 1169. That 10-point difference translates to roughly 0.9% in average performance. Both processors sit at the 33rd percentile among all CPUs, meaning they are in the same performance tier overall, with the i5-4440 holding a slim edge.

Architecture Differences

The two processors come from different architectural generations and use different sockets. The i5-4440 is based on the Haswell architecture, uses the Intel Socket 1150, and belongs to the Core i5 (Haswell) generation. The i5-3570S is built on Ivy Bridge, uses Intel Socket 1155, and is part of the Core i5 (Ivy Bridge) generation. Both are manufactured on the same 22 nm process node at Intel, but the die sizes differ: the Haswell chip has a die size of 177 mm² and contains 1,400 million transistors, while the Ivy Bridge part has a smaller 133 mm² die with no transistor count listed in the data.

Core and cache configurations are identical on paper. Both have 4 cores and 4 threads, with 64 KB of L1 cache per core and 256 KB of L2 cache per core. Shared L3 is 6 MB on both. Memory support is also the same: DDR3 with a dual-channel memory bus, and neither supports ECC memory. Both have PCIe Gen 3, though the i5-3570S specifies "16 Lanes (CPU only)" while the i5-4440 simply lists "Gen 3."

The integrated graphics differ. The i5-4440 includes Intel HD 4600, while the i5-3570S has Intel HD 2500. This matters for users who rely on the iGPU for display output or light graphics work, though neither is a gaming solution. The base clocks are identical at 3.10 GHz, but the boost clocks diverge: the i5-4440 boosts to 3.30 GHz while the i5-3570S boosts to 3.80 GHz. That 500 MHz boost advantage for the older chip is interesting because it does not translate into a benchmark win.

Thermal design power is a significant differentiator. The i5-4440 has a TDP of 84 watts, while the i5-3570S is rated at 65 watts. That 19-watt difference makes the i5-3570S a more power-efficient part on paper, even though it boosts higher. The release dates also differ: the i5-3570S launched on 2012-05-31, while the i5-4440 launched on 2013-08-31, roughly 15 months later.

Where Each One Wins

The i5-4440 wins in every benchmark category where both have data. In multicore workloads, it leads by 2.0% in Cinebench R15, 2.1% in R20, and 2.2% in R23. In single-core workloads, it leads by 1.8% in R15, 2.1% in R20, and 2.1% in R23. This means the i5-4440 is the better choice for both heavily threaded rendering tasks and lightly threaded applications, based purely on the Cinebench suite.

The i5-3570S does have one advantage that is not captured in the head-to-head benchmarks: its Geekbench scores. With 1793 multicore and 632 single-core, it has a measurable performance profile in that test. However, without a corresponding Geekbench result for the i5-4440, it is impossible to determine which chip would win in that specific benchmark. The data simply does not allow that comparison.

The i5-3570S also has the lower TDP at 65 watts versus 84 watts. For a system builder prioritizing thermal output or power draw, the i5-3570S is the more efficient option. It also has a higher boost clock at 3.80 GHz versus 3.30 GHz, which could theoretically benefit bursty workloads that rely on a single thread reaching maximum frequency, though the benchmark data does not show this translating into a win.

For users with an existing Socket 1155 motherboard, the i5-3570S is the drop-in choice; for those on Socket 1150, the i5-4440 fits. Neither has an unlocked multiplier, so overclocking headroom is not a distinguishing factor. The i5-4440's newer Haswell architecture and stronger Cinebench results make it the performance pick, while the i5-3570S offers lower power consumption and a higher boost clock but loses on raw benchmark scores.
