Intel Core i5-3570T vs Intel Core i5-4430 Comparison

Where Each One Wins

The benchmark data gives a clear, one-sided picture. The Intel Core i5-4430 wins every single head-to-head comparison recorded in the database, taking all five wins against zero for the Intel Core i5-3570T. This is not a close contest by any measure. The i5-4430 leads in every Cinebench test, both multi-core and single-core, with deltas between 20.5% and 20.8%. There is no workload category in the recorded measurements where the i5-3570T comes out ahead.

The i5-4430’s advantage is consistent across rendering workloads. In Cinebench R15 multi-core, it scores 400 versus 331 for the i5-3570T, a 20.8% lead. In Cinebench R20 multi-core, the gap is 1669 against 1383, a 20.7% margin. The R23 multi-core test shows 3974 versus 3293, again 20.7%. Single-core results follow the same pattern: R20 single-core is 235 versus 195 (20.5%), and R23 single-core is 561 versus 465 (20.6%). The i5-4430 is faster in both heavily threaded and lightly threaded scenarios, meaning it simply has the higher performance ceiling across the board.

The i5-3570T does have one redeeming characteristic in the recorded data, but it is not a performance one. Its TDP is 45 watts, compared to 84 watts for the i5-4430. That is a substantial difference in thermal design power, suggesting the i5-3570T is built for lower power consumption and heat output. However, the benchmark results show that this efficiency comes at a direct cost: it trails the i5-4430 by roughly one-fifth in every rendering test. The i5-3570T also has a higher boost clock (3.30 GHz versus 3.20 GHz), but that does not translate into any measured win. The i5-4430’s higher base clock (3.00 GHz versus 2.30 GHz) and newer architecture appear to dominate.

Looking at the broader database context, both processors sit near the same percentile. The i5-4430 is in the 33rd percentile of all CPUs, while the i5-3570T is in the 32nd. Their average benchmark scores are close: 1149 for the i5-4430 and 1136 for the i5-3570T. That places them in the same performance tier overall, even though the head-to-head Cinebench results show a clear winner. The i5-4430’s nearest rivals include the Intel Core i7-3612QE (delta 0.2%), AMD Opteron 4284 (0.2%), Intel Core i7-2600S (0.3%), and Intel Core i3-8145UE (-0.4%). The i5-3570T’s nearest rivals are the Intel Core i5-2550K (0%), Intel Xeon E5640 (-0.1%), Intel Core i3-N300 (0.1%), and AMD Athlon Silver PRO 3125GE (-0.2%). These figures show both parts are competitive within their immediate neighborhood, but the i5-4430 has the edge in direct comparison.

The Verdict

The data points to a straightforward recommendation. For anyone prioritizing raw performance in Cinebench workloads, the Intel Core i5-4430 is the clear choice. It wins all five recorded head-to-head tests with margins above 20%. The i5-4430 is also built on a newer architecture (Haswell versus Ivy Bridge) and uses the Intel Socket 1150, which is a different platform from the i5-3570T’s Socket 1155. If the goal is maximum rendering speed, the i5-4430 wins without qualification.

The i5-3570T, however, has its own rationale. Its 45 watt TDP is nearly half that of the i5-4430’s 84 watts. This makes it the better option for systems where power draw and heat dissipation are the primary constraints, such as compact builds or fanless configurations. The performance deficit is real and consistent, but for workloads that are not rendering-bound, the lower power envelope may be worth more than the 20% speed gap. The i5-3570T also has a higher boost clock (3.30 GHz versus 3.20 GHz), which could help in short bursts, though the recorded benchmarks do not show any advantage from this.

For most users, the verdict is the i5-4430. It is faster in every measured test, has a higher base clock, and belongs to a newer generation. The i5-3570T is for niche scenarios where power efficiency trumps performance. There is no scenario in the data where the i5-3570T wins a benchmark, so the choice comes down to whether the 45 watt TDP is worth the 20% performance loss. The database’s percentile rankings reinforce this: both are mid-range parts, but the i5-4430 sits slightly higher (33rd versus 32nd percentile) and has a higher average score (1149 versus 1136).

Head-to-Head Benchmarks

The head-to-head results are remarkably uniform. Every test shows the i5-4430 winning by a margin between 20.5% and 20.8%. This consistency suggests a fundamental performance gap rather than a workload-specific anomaly. The multi-core tests show the largest absolute differences. In Cinebench R15 multi-core, the i5-4430 scores 400 against 331, a delta of 20.8%. That is the largest percentage gap in the set. Cinebench R20 multi-core is 1669 versus 1383 (20.7%), and R23 multi-core is 3974 versus 3293 (20.7%). These three tests all measure heavily threaded performance, and the i5-4430’s lead is steady.

Single-core results are slightly smaller in percentage terms but still decisive. Cinebench R20 single-core shows 235 versus 195, a 20.5% delta. Cinebench R23 single-core shows 561 versus 465, a 20.6% delta. The fact that single-core margins are nearly as large as multi-core ones indicates the i5-4430’s advantage is not just about core scaling. Its per-core performance is simply higher, likely due to the newer Haswell architecture and higher base clock. The i5-3570T’s higher boost clock (3.30 GHz) does not compensate for its lower base clock (2.30 GHz) in these sustained tests.

There are no recorded wins for the i5-3570T in any head-to-head benchmark. The database lists zero wins for it. This is a complete sweep. The i5-3570T does have a Geekbench single-core score of 578 and a Geekbench multi-core score of 1705, but there is no corresponding Geekbench entry for the i5-4430 in the head-to-head data, so those cannot be compared directly. The Cinebench suite alone is enough to establish the performance hierarchy.

Q: Do both processors support the same memory type?

A: Yes, both support DDR3 memory with dual-channel memory buses. They also both lack ECC memory support. However, they use different sockets: the i5-4430 uses Intel Socket 1150, while the i5-3570T uses Intel Socket 1155.

Q: Which processor has a newer architecture?

A: The i5-4430 uses the Haswell architecture, while the i5-3570T uses Ivy Bridge. Both are built on a 22 nm process node with 1,400 million transistors, but the i5-4430 has a larger die size at 177 mm² versus 160 mm² for the i5-3570T.

Architecture Differences

The two processors represent different generations of Intel’s Core i5 lineup. The i5-4430 is based on the Haswell architecture and belongs to the Core i5 (Haswell) generation. The i5-3570T is based on Ivy Bridge and belongs to the Core i5 (Ivy Bridge) generation. Both are built on Intel’s 22 nm process node and use 1,400 million transistors, but the i5-4430 has a larger die size at 177 mm² compared to 160 mm² for the i5-3570T. The larger die likely reflects the newer architecture’s additional features and integrated graphics.

Cache configurations are identical. Both have 64 KB of L1 cache per core, 256 KB of L2 cache per core, and 6 MB of shared L3 cache. The core and thread counts are also the same: 4 cores and 4 threads each. Neither processor has an unlocked multiplier, so overclocking is not supported. The base clocks differ significantly: the i5-4430 runs at 3.00 GHz, while the i5-3570T runs at 2.30 GHz. The boost clocks are closer, with the i5-4430 at 3.20 GHz and the i5-3570T at 3.30 GHz, giving the i5-3570T a slight peak-clock advantage that does not show up in benchmark wins.

The sockets are different. The i5-4430 uses Intel Socket 1150, while the i5-3570T uses Intel Socket 1155. This means they are not interchangeable on the same motherboard. The i5-3570T’s PCIe support is listed as Gen 3 with 16 lanes (CPU only), while the i5-4430 supports PCIe Gen 3 without a lane count specified. Integrated graphics also differ: the i5-4430 includes Intel HD 4600, while the i5-3570T includes Intel HD 2500. The i5-4430’s newer graphics solution is part of the Haswell package.

Memory support is identical in type: both support DDR3 with dual-channel memory buses, and neither supports ECC memory. The i5-3570T’s TDP of 45 watts is a major architectural difference, reflecting a lower power design that likely contributes to its lower performance. The i5-4430’s 84 watt TDP is nearly double, which aligns with its higher base clock and consistent benchmark lead. Release dates also differ: the i5-3570T was released on 2012-04-28, while the i5-4430 came later on 2013-06-01. The newer release date for the i5-4430 corresponds to its Haswell architecture, which is the primary driver of its performance advantage in the recorded data.
