Intel Core i5-4670S vs Intel Core i5-5575R Comparison

Head-to-Head Benchmarks

The recorded data paints a remarkably one-sided picture. Across all eight benchmark comparisons, the Intel Core i5-4670S takes the win, with the largest margin appearing in Geekbench single-core performance. There, the i5-4670S scores 1184 against 1072 for the i5-5575R, a delta of 10.4%. That is a substantial gap for two desktop processors from the same family, and it suggests the older Haswell part holds a clear advantage in lightly threaded workloads.

The Cinebench results tell a similar story, though with narrower margins. In Cinebench R15 multi-core, the i5-4670S posts 448 versus 435, a 3% lead. The single-core test in R15 shows 63 against 61, a 3.3% edge. Moving to Cinebench R20, the multi-core score is 1870 for the i5-4670S and 1816 for the i5-5575R, again a 3% difference. Single-core R20 sees 263 versus 256, a 2.7% gap. The newer Cinebench R23 test repeats the pattern: multi-core 4454 against 4324, single-core 628 against 610, both a 3% advantage for the i5-4670S.

The Geekbench multi-core result is closer, with the i5-4670S scoring 3300 and the i5-5575R at 3247, a 1.6% difference. This smaller margin hints that when all four cores are engaged, the newer architecture of the i5-5575R partially compensates for its lower clock speeds. Still, the outcome is consistent: the i5-4670S wins every head-to-head test, with zero wins for the i5-5575R.

What does this mean in context? The i5-4670S sits at the 38th percentile of all CPUs in the database, with an average benchmark score of 1526. Its closest rival, the Intel Core i5-7440HQ, scores 1527, a 0% delta. The i5-5575R also lands at the 38th percentile but with a lower average score of 1478. Its nearest rival, the Intel Core i5-7500T, scores 1483, a -0.4% delta. So while both processors occupy the same percentile tier, the i5-4670S is measurably faster on average, and the head-to-head numbers confirm this is not a statistical fluke.

Architecture Differences

The two chips come from different architectural generations, and that shows in several key specifications. The i5-4670S is built on the Haswell architecture, using a 22 nm process node with 1,400 million transistors on a 177 mm² die. The i5-5575R, in contrast, uses the Broadwell architecture on a 14 nm process node, with a slightly larger die at 182 mm². The transistor count for the i5-5575R is not recorded, but the shift to 14 nm is significant: it represents a newer manufacturing generation that typically allows for better power efficiency per clock.

Both processors have four cores and four threads, so parallel thread counts are identical. Cache configurations differ, however. The i5-4670S has 64 KB of L1 per core, 256 KB of L2 per core, and 6 MB of shared L3. The i5-5575R matches the L1 and L2 sizes but has only 4 MB of shared L3. That 2 MB difference could matter in workloads with large working sets, though the benchmark data suggests it does not overcome the clock speed gap.

Clock speeds are a major differentiator. The i5-4670S has a base clock of 3.10 GHz and a boost clock of 3.80 GHz. The i5-5575R runs at 2.80 GHz base and 3.30 GHz boost. That is a 300 MHz difference at base and a 500 MHz difference at boost, which explains why the older Haswell chip wins every benchmark despite having a smaller L3 cache and an older process node. The i5-5575R's integrated graphics are notably stronger, however: it ships with Iris Pro Graphics 6200, while the i5-4670S has Intel HD 4600. This is a meaningful architectural distinction, as Iris Pro includes embedded DRAM that can accelerate graphics workloads.

The memory support is DDR3 for both, with dual-channel buses. The i5-5575R lists a memory bandwidth of 29.9 GB/s, while the i5-4670S does not have a recorded bandwidth figure. PCIe support is Gen 3 for both, but the i5-5575R specifies 16 lanes (CPU only), while the i5-4670S simply lists "Gen 3" without lane details. Neither supports ECC memory, and neither has an unlocked multiplier.

Socket differences are also notable. The i5-4670S uses Intel Socket 1150, a socketed desktop platform. The i5-5575R uses Intel BGA 1364, meaning it is ball-grid array soldered directly to the motherboard, not user-replaceable. This is a practical difference for anyone building or upgrading a system.

Where Each One Wins

The i5-4670S wins every recorded benchmark, so the use-case split is more about degrees of advantage than about different domains. The largest win is in Geekbench single-core, where the i5-4670S leads by 10.4%. This is the strongest signal that the Haswell part is the better choice for software that relies heavily on a single thread: older games, some productivity apps, and lightly threaded legacy applications. The 3.80 GHz boost clock gives it a clear edge in bursty, single-core workloads.

In multi-core tests, the i5-4670S still wins, but by a smaller margin of 1.6% to 3%. This suggests that the i5-5575R's newer 14 nm architecture and Iris Pro graphics help it stay competitive when all four cores are active, even though it has a lower clock speed and less L3 cache. For rendering tasks in Cinebench R15, R20, and R23, the i5-4670S is consistently about 3% ahead. For general multi-core Geekbench work, the gap narrows to 1.6%.

The i5-5575R does not win any benchmark, but its advantages are not visible in the recorded CPU tests. Its Iris Pro Graphics 6200 is a substantially more capable integrated GPU than the HD 4600 in the i5-4670S. In the database, this means the i5-5575R would be the better pick for a system that needs decent graphics without a discrete card, such as a compact media PC or a light gaming rig. The soldered BGA 1364 socket also points to pre-built or embedded designs, where the user is not expected to upgrade the CPU later.

The i5-4670S, with its Socket 1150, is the more flexible choice for a DIY builder. It offers higher raw CPU performance across the board, and its socketed design allows for replacement or upgrade. The data shows no scenario among the recorded benchmarks where the i5-5575R comes out ahead in CPU-bound tasks.

Specification Differences

The two processors differ in several recorded specifications. The base clock is 3.10 GHz for the i5-4670S versus 2.80 GHz for the i5-5575R. The boost clock is 3.80 GHz versus 3.30 GHz. The process node is 22 nm for the i5-4670S and 14 nm for the i5-5575R. The i5-4670S has 1,400 million transistors, while the i5-5575R has no recorded transistor count. Die size is 177 mm² for the i5-4670S and 182 mm² for the i5-5575R.

L3 cache is 6 MB shared for the i5-4670S and 4 MB shared for the i5-5575R. The i5-5575R lists a memory bandwidth of 29.9 GB/s, which the i5-4670S does not. The socket differs: Intel Socket 1150 for the i5-4670S, Intel BGA 1364 for the i5-5575R. Integrated graphics differ as well: Intel HD 4600 versus Iris Pro Graphics 6200. The i5-5575R specifies PCIe Gen 3 with 16 lanes (CPU only), while the i5-4670S only states Gen 3.

The release dates are different: the i5-4670S launched on June 1, 2013, while the i5-5575R launched on May 14, 2015. The i5-5575R carries a launch MSRP of $265, while the i5-4670S has no recorded launch price. The i5-5575R has a production status of "Active," while the i5-4670S has no recorded status. Part numbers also differ: SR14K for the i5-4670S, SR2AK for the i5-5575R. Both have four cores, four threads, 65 W TDP, DDR3 memory support, dual-channel memory buses, no ECC support, and locked multipliers.

The Verdict

Based strictly on the recorded data, the Intel Core i5-4670S is the faster CPU in every measured category. It leads in all eight head-to-head benchmarks, with deltas ranging from 1.6% in Geekbench multi-core to 10.4% in Geekbench single-core. Its higher base and boost clocks (3.10 GHz and 3.80 GHz versus 2.80 GHz and 3.30 GHz) and larger 6 MB L3 cache give it a consistent edge over the newer Broadwell chip. The i5-4670S also holds a slightly higher average benchmark score of 1526 versus 1478, and both sit at the same 38th percentile of all CPUs.

For a user prioritizing raw CPU performance, especially in single-threaded tasks, the i5-4670S is the clear choice from the data. Its socketed LGA 1150 design also makes it more practical for a DIY desktop build where the processor can be replaced. The i5-5575R, by contrast, offers no CPU performance win in the recorded benchmarks. Its advantages lie outside the CPU core: the Iris Pro Graphics 6200 is a stronger integrated GPU, and the 14 nm process node represents a newer manufacturing generation. The i5-5575R also has an "Active" production status, while the i5-4670S has no recorded status, which may matter for availability.

The verdict depends on the use case. If the workload is CPU-bound, the data says to pick the i5-4670S. If the system relies on integrated graphics and does not demand maximum CPU throughput, the i5-5575R is the only one of the two with a meaningful edge in that area, though that edge is not captured in the recorded CPU benchmarks. The i5-5575R's soldered BGA 1364 socket makes it a fit for pre-built or embedded systems, not for a user who wants to swap processors later. Given the benchmark results, the i5-4670S is the stronger processor for general computing, rendering, and single-threaded applications, while the i5-5575R is best considered for scenarios where its integrated GPU and smaller footprint matter more than raw core performance.
