CPU Comparison

# Intel Atom x7425E vs Intel Core i5-4670T

The Intel Atom x7425E and Intel Core i5-4670T are both quad-core, four-thread processors, but they represent radically different eras and design philosophies. The benchmark data shows the Atom x7425E winning every single head-to-head test, with margins ranging from 14.8% to 15.4% across Cinebench workloads. However, their average benchmark scores are nearly identical, 1273 for the Atom versus 1271 for the i5-4670T, placing both in the 35th percentile of all CPUs. This creates an interesting dynamic: the newer Atom is consistently faster in raw compute tests, yet the overall performance picture is much closer than the per-test margins suggest.

Where Each One Wins

The Intel Atom x7425E wins across every benchmark in the comparison suite. In Cinebench R15 multicore, it scores 443 against the i5-4670T's 384, a 15.4% advantage. The single-core R15 test shows a similar story: 62 versus 54, a 14.8% lead. Moving to Cinebench R20, the Atom posts 1849 multicore and 260 single-core, compared to 1604 and 226 for the i5-4670T, margins of 15.3% and 15.0%, respectively. In Cinebench R23, the Atom delivers 4403 multicore and 621 single-core, beating the i5-4670T's 3820 and 539 by 15.3% and 15.2%. The Atom wins all six head-to-head tests, with no benchmark going to the i5-4670T.

That said, the i5-4670T has its own areas of structural advantage, even if they don't translate to benchmark wins. It uses dual-channel memory, while the Atom is limited to single-channel. The i5-4670T also supports DDR3 exclusively, whereas the Atom supports both DDR4 and DDR5. These memory differences don't show up in the Cinebench results, but they affect real-world memory bandwidth scenarios. The i5-4670T also has a higher base clock (2.30 GHz versus 1.50 GHz), though the Atom's boost clock is slightly higher (3.40 GHz versus 3.30 GHz). The i5-4670T's higher thermal design power (45W versus 12W) suggests it can sustain higher clocks under load, yet the benchmark data shows the Atom pulling ahead anyway.

Architecture Differences

The architecture gap between these two processors is substantial. The Atom x7425E uses Intel's Alder Lake-N architecture, built on a 10 nm process, with Gracemont efficiency cores. The i5-4670T is a Haswell-era desktop chip on Intel's 22 nm process, featuring 1,400 million transistors on a 177 mm² die. The process node difference alone, 10 nm versus 22 nm, explains much of the efficiency gap, with the Atom's TDP of 12W versus the i5-4670T's 45W.

Cache configurations differ notably. The Atom provides 96 KB of L1 cache per core, 2 MB of shared L2, and 6 MB of shared L3. The i5-4670T offers 64 KB of L1 per core, 256 KB of L2 per core, and 6 MB of shared L3. While their total L3 is identical at 6 MB, the L2 allocation is fundamentally different: the Atom shares a 2 MB pool across all cores, while the i5-4670T gives each core its own 256 KB slice.

Memory support is another differentiator. The Atom supports DDR4 and DDR5 with a single-channel memory bus and 38.4 GB/s of bandwidth. The i5-4670T supports only DDR3 but uses a dual-channel bus, which can offset some of the bandwidth disadvantage of older memory technology. Neither chip supports ECC memory. Both use PCIe Gen 3, though the Atom specifies 9 lanes (CPU only) while the i5-4670T lists PCIe Gen 3 without lane count details.

Integrated graphics also differ: the Atom includes UHD Graphics 24EU, while the i5-4670T uses Intel HD 4600. The Atom is classified as a mobile processor on Intel BGA 1264, released in January 2023 with a launch MSRP of $58. The i5-4670T is a desktop part on Intel Socket 1150, released in June 2013. The Atom remains in active production, while the i5-4670T's production status is not listed.

The Verdict

The benchmark data is unambiguous: the Intel Atom x7425E outperforms the Intel Core i5-4670T in every Cinebench test. The Atom's multicore advantage ranges from 15.3% to 15.4% across R15, R20, and R23, while its single-core lead sits between 14.8% and 15.2%. This consistency across all six tests suggests a fundamental architectural superiority rather than a workload-specific quirk.

For buyers choosing between these two, the decision hinges on platform and efficiency rather than raw performance. The Atom x7425E delivers higher benchmark scores at a fraction of the power draw, 12W versus 45W, and supports modern DDR4/DDR5 memory. It is also actively produced, with a launch MSRP of $58, making it a current, available option. The i5-4670T, by contrast, is a 2013-era desktop chip with DDR3-only support and no production status listed. Its only structural advantages are dual-channel memory and a higher base clock, neither of which translates to a benchmark win.

The data shows a clear winner for compute performance, but the i5-4670T remains competitive in average benchmark score (1271 versus 1273), suggesting that real-world mixed workloads may not feel dramatically different. Still, given the Atom's wins across the board, lower power draw, and modern memory support, the benchmark evidence favors the Atom x7425E for anyone who values current technology and efficiency.

Head-to-Head Benchmarks

The largest single benchmark win for the Atom x7425E comes in Cinebench R15 multicore, where it scores 443 against the i5-4670T's 384, a 15.4% margin. This is the widest gap of any test in the comparison. The R20 multicore test shows a nearly identical 15.3% advantage (1849 versus 1604), and R23 multicore also lands at 15.3% (4403 versus 3820). These three multicore results paint a consistent picture: the Atom is roughly 15% faster across all Cinebench versions.

Single-core results follow the same trend with slightly narrower margins. In Cinebench R15 single-core, the Atom scores 62 versus 54, a 14.8% lead. R20 single-core shows 260 versus 226, a 15.0% advantage. R23 single-core delivers 621 versus 539, a 15.2% gap. The spread between the smallest single-core margin (14.8%) and the largest multicore margin (15.4%) is just 0.6 percentage points, indicating that the Atom's advantage is consistent regardless of thread count or Cinebench version.

The i5-4670T does have an additional Geekbench result in its data, 2563 multicore and 977 single-core, but no corresponding Geekbench score exists for the Atom in the head-to-head comparison, so these cannot be directly compared. The i5-4670T's percentile ranking (35th) matches the Atom's (35th), and their nearest rivals include the same processors: the Intel Core i5-4430S (average score 1274), the Intel Core i3-1005G1 (1265), and the Intel Xeon W-2102 (1264). The i5-4670T's delta to the i5-4430S is -0.2%, while the Atom's delta to the same rival is 0%, placing them within a hair's breadth of each other in overall performance.
