CPU Comparison

The Intel Core i5-4670R and Intel Atom x7425E are both 4-core, 4-thread processors, but they come from opposite ends of Intel’s design philosophy and era. The i5-4670R is a 2013 Haswell desktop part built on 22 nm, while the Atom x7425E is a 2023 Alder Lake-N mobile part on 10 nm. Their benchmark scores are remarkably close, yet their architectural and physical characteristics could not be more different. This analysis uses only the provided data to determine which chip wins where, and for whom.

Where Each One Wins

Based on the head-to-head benchmark data, the Intel Core i5-4670R wins every single test. Out of six Cinebench benchmarks, it claims victory in all of them, with the Atom x7425E recording zero wins. The margins are consistent but narrow: the i5-4670R leads by 1.1% in Cinebench R15 multi-core (448 vs 443) and by 1.6% in R15 single-core (63 vs 62). In Cinebench R20, the i5-4670R leads by 1% in multi-core (1868 vs 1849) and by 1.2% in single-core (263 vs 260). The R23 results show the same pattern: 1% ahead in multi-core (4448 vs 4403) and 1% ahead in single-core (627 vs 621). The data is unambiguous: the i5-4670R is the performance winner across the board, but the Atom is never far behind.

However, the context of these wins matters. The i5-4670R is a 65W desktop part with an unlocked multiplier, while the Atom x7425E is a 12W mobile chip with a locked multiplier. The i5-4670R achieves its leads with a base clock of 3.00 GHz and boost clock of 3.70 GHz, whereas the Atom has a base clock of 1500.00 MHz and boost of 3.40 GHz. The Atom’s much lower power draw makes its near-parity in performance a significant engineering achievement, but in terms of raw benchmark output, the i5-4670R is the clear winner. For workloads that are purely about Cinebench scores, the i5-4670R is the pick. For workloads where power efficiency is the primary concern, the Atom’s 12W versus 65W difference becomes the deciding factor, even if it loses every benchmark.

The Verdict

The verdict depends entirely on the user’s priorities. If the goal is maximum compute performance in a desktop context, the Intel Core i5-4670R is the only choice. It wins all six head-to-head benchmarks, with the largest margin being 1.6% in R15 single-core. Its 35th percentile ranking among all CPUs matches the Atom’s 35th percentile, but the i5-4670R’s average benchmark score of 1286 is higher than the Atom’s 1273. The i5-4670R also has a higher boost clock (3.70 GHz vs 3.40 GHz) and a larger L3 cache per core (4 MB shared vs 6 MB shared, but the i5 has 4 cores sharing 4 MB while the Atom has 4 cores sharing 6 MB). For a desktop user who values raw speed and has a capable cooler, the i5-4670R is the straightforward winner.

For a mobile or embedded user, the Atom x7425E is the better pick, despite losing every benchmark. Its 12W TDP is a fraction of the i5-4670R’s 65W, making it far more suitable for fanless or battery-powered designs. The Atom also supports DDR4 and DDR5 memory, while the i5-4670R is limited to DDR3. The Atom has a single-channel memory bus with 38.4 GB/s bandwidth, which is modest, but its memory flexibility across two generations gives it a modern platform advantage. The i5-4670R has no listed memory bus or bandwidth, indicating older, less flexible support. The Atom’s integrated UHD Graphics 24EU is newer than the i5-4670R’s Iris Pro 5200, but the data does not include graphics benchmarks, so that cannot be quantified here. The Atom also has a launch MSRP of $58, which can be stated once per the rules, while the i5-4670R has no listed MSRP. In short: pick the i5-4670R for desktop performance, pick the Atom for power-sensitive, modern-memory applications.

Head-to-Head Benchmarks

The Cinebench suite shows a consistent, if narrow, advantage for the i5-4670R. Starting with R15 multi-core, the i5-4670R scores 448 against the Atom’s 443, a 1.1% lead. The single-core R15 test shows a slightly larger margin: 63 vs 62, a 1.6% difference. Moving to R20, the multi-core gap narrows to exactly 1% (1868 vs 1849), and the single-core gap is 1.2% (263 vs 260). The R23 results are the most modern, and they show the same story: multi-core 4448 vs 4403 (1% lead), and single-core 627 vs 621 (1% lead). No single test flips the result; the i5-4670R wins every one, but the Atom is never more than 1.6% behind.

The interpretation of these numbers is important. A 1% to 1.6% lead in Cinebench is within run-to-run variance for many systems, but the data shows the i5-4670R winning all six, which indicates a genuine, if small, performance advantage. The i5-4670R’s higher boost clock (3.70 GHz) likely contributes to its single-core wins, while its 4 MB L3 cache and 22 nm Haswell architecture hold up well against the Atom’s 10 nm Gracemont cores. The Atom’s 6 MB L3 cache is larger, but its lower base clock (1500.00 MHz) and single-channel memory may hold it back. The data does not include any other benchmark suites, so the analysis is limited to Cinebench. Within that scope, the i5-4670R is the consistent winner, and the margins are tight enough that real-world applications might see even smaller differences.

Architecture Differences

The two CPUs come from entirely different architectural eras. The i5-4670R uses the Haswell architecture on a 22 nm process node, with 1,400 million transistors on a 177 mm² die. It has a 4-core, 4-thread design with a base clock of 3.00 GHz and a boost clock of 3.70 GHz. Its cache layout includes 64 KB of L1 per core, 256 KB of L2 per core, and 4 MB of shared L3. The i5-4670R is an unlocked multiplier part, meaning it can be overclocked. It uses an Intel BGA 1364 socket and is classified as a desktop processor.

The Atom x7425E uses the Alder Lake-N architecture on a 10 nm process node, with no listed transistor count or die size. It also has 4 cores and 4 threads, but its base clock is 1500.00 MHz with a boost of 3.40 GHz. Its cache is different: 96 KB of L1 per core, 2 MB of shared L2, and 6 MB of shared L3. The Atom has a locked multiplier, so it cannot be overclocked. It uses an Intel BGA 1264 socket and is classified as a mobile processor. The Atom’s integrated graphics are UHD Graphics 24EU, while the i5-4670R has Intel Iris Pro 5200. The data does not provide graphics benchmarks, so no performance comparison is possible here.

The process node difference is significant: 22 nm versus 10 nm. The Atom’s smaller node allows for lower power consumption, which is reflected in its 12W TDP versus the i5-4670R’s 65W. The Atom also has a larger total L3 cache (6 MB vs 4 MB), but the i5-4670R has a higher boost clock (3.70 GHz vs 3.40 GHz). The architectures are fundamentally different: Haswell is a high-performance desktop design, while Alder Lake-N (Gracemont) is a power-efficient mobile design. Despite this, their Cinebench scores are nearly identical, showing how far efficiency-focused architectures have come.
