Intel Atom x7211RE vs Intel Core i5-1335UE Comparison

The Verdict

The Intel Core i5-1335UE is the clear performance winner in every recorded benchmark, making it the only choice for any workload that depends on raw compute throughput. The data shows a consistent and massive gap: the i5-1335UE outperforms the Atom x7211RE by roughly 457% to 461% across all Cinebench tests, both single-core and multi-core. For users who need responsive single-threaded performance or substantial multi-threaded capability, the i5-1335UE is the only defensible option from this dataset.

The Intel Atom x7211RE, by contrast, is a 6 W part with two cores and two threads. Its benchmark results are far lower across the board, but the recorded data also shows it shares the same 10 nm process node and the same DDR4/DDR5 memory support as the i5-1335UE. The Atom also posts a higher per-core L1 cache (96 KB per core versus 80 KB per core) and a larger per-core L2 allocation (2 MB shared across two cores versus 1.25 MB per core). None of those cache advantages translate into better scores, however. The Atom's single-thread Cinebench R23 score of 254 is less than 18% of the i5-1335UE's 1419.

The database also places both chips at the 51st percentile among all CPUs, which is an unusual alignment given the performance disparity. The Atom's average benchmark score of 2811 is driven by a broader suite of Passmark tests that the i5-1335UE does not have recorded, including data compression, encryption, and integer math. That average score places the Atom near the Intel Core i5-8600K (0.2% above), the AMD Ryzen 3 PRO 5450U (0.6% below), and the Intel Core i5-11300H (0.7% above). The i5-1335UE's average of 2907 sits near the AMD Ryzen 5 PRO 1600 (0.1% below) and the Intel Xeon E-2414 (0.1% above). This suggests the Atom's average is inflated by Passmark workloads that are not directly comparable to the Cinebench results, while the i5-1335UE's average reflects its Cinebench-focused dataset.

For a buyer deciding strictly on the data: choose the i5-1335UE for any general-purpose computing, content creation, or development workload where clock speed and core count matter. Choose the Atom x7211RE only if the 6 W TDP and the $42 launch MSRP are decisive factors, and even then, be aware that its Cinebench scores are dramatically lower. The Atom's single-channel memory bus and PCIe Gen 3 lanes (9 lanes) versus the i5-1335UE's dual-channel memory and PCIe Gen 4 (8 lanes) further reinforce that the Atom is a low-power embedded part, not a general-purpose performer.

A: The i5-1335UE has a boost clock of 4.50 GHz, while the Atom x7211RE has a boost clock of 3.20 GHz. The i5 also has a higher base clock: 1300 MHz versus 1000 MHz.

Architecture Differences

The two processors come from different architectural families. The Intel Core i5-1335UE is built on Raptor Lake, specifically the Raptor Lake-U codename, and belongs to the Core i5 (Raptor Lake-U) generation. The Intel Atom x7211RE is built on Amston Lake, with the Atom (Gracemont) generation label. Both use a 10 nm process node and are fabricated by Intel, but the underlying core designs differ substantially.

The i5-1335UE is a hybrid-style part with 10 cores and 12 threads, indicating a mix of performance and efficiency cores, though the exact core type split is not recorded. The Atom x7211RE has only 2 cores and 2 threads, all based on the Gracemont architecture. Gracemont is Intel's efficiency-oriented core design, which explains the Atom's low TDP of 6 W despite the same process node.

Cache organization differs as well. The i5-1335UE has 80 KB of L1 cache per core, 1.25 MB of L2 per core, and 12 MB of shared L3. The Atom x7211RE has 96 KB of L1 per core, 2 MB of shared L2, and 6 MB of shared L3. The Atom's larger per-core L1 and per-core L2 (when divided by two cores) does not compensate for the i5's far higher clock speeds and core count in the recorded benchmarks.

Memory architecture also separates the two. The i5-1335UE supports dual-channel memory, while the Atom x7211RE supports single-channel memory with a recorded bandwidth of 38.4 GB/s. The i5 has no memory bandwidth figure in the database, but dual-channel support generally provides more headroom. PCIe connectivity differs too: the i5 offers Gen 4 with 8 lanes (CPU only), while the Atom offers Gen 3 with 9 lanes (CPU only). Integrated graphics are another split: the i5 uses Iris Xe Graphics with 80 execution units, while the Atom uses UHD Graphics with 16 execution units.

The release dates are also different. The i5-1335UE was released on 2023-01-03, while the Atom x7211RE was released on 2024-04-07. Both are listed as Active in production status, and neither has an unlocked multiplier.

Head-to-Head Benchmarks

The head-to-head data contains five Cinebench comparisons, and the i5-1335UE wins all five. There are no recorded wins for the Atom x7211RE in this section.

The largest delta is in Cinebench R20 single-core, where the i5-1335UE scores 595 against the Atom's 106, a 461.3% advantage. That is the biggest percentage gap in the dataset. The smallest gap is in Cinebench R23 multi-core, where the i5 scores 10052 versus 1804, a 457.2% difference. The delta values are remarkably consistent across tests: 459.7% in R15 multi-core, 457.6% in R20 multi-core, 461.3% in R20 single-core, 457.2% in R23 multi-core, and 458.7% in R23 single-core.

In absolute terms, the i5-1335UE's multi-core scores are roughly five to six times higher than the Atom's. For example, in Cinebench R15 multi-core, the i5 posts 1013 versus 181. In Cinebench R23 multi-core, the i5 posts 10052 versus 1804. The single-core gap is just as stark: the i5's R23 single-core score of 1419 is more than five times the Atom's 254.

The database also records an average benchmark score for each chip: the i5-1335UE averages 2907, while the Atom x7211RE averages 2811, a much smaller gap than the Cinebench results suggest. This is because the Atom has 16 recorded benchmarks, including Passmark tests such as data compression (20820), data encryption (1556), integer math (6517), floating point math (4303), and single-thread (1317). The i5-1335UE only has six Cinebench results and no Passmark entries. The Atom's average is therefore not directly comparable to the i5's average; the head-to-head Cinebench data is the reliable comparison.

Where Each One Wins

The i5-1335UE wins every recorded head-to-head benchmark, so its strengths are clear: multi-threaded rendering, single-threaded responsiveness, and any workload that scales with core count or clock speed. Its 10 cores and 12 threads, combined with a 4.50 GHz boost clock, make it the superior choice for Cinebench-style rendering tasks, which are heavily threaded. The i5 also leads in single-core tests by over 460%, which affects everyday application responsiveness, browser performance, and lightly threaded productivity apps. The dual-channel memory bus and PCIe Gen 4 support further favor the i5 for systems that need faster memory and storage throughput.

The Atom x7211RE has no recorded benchmark wins against the i5. Its advantages are structural rather than performance-based. The 6 W TDP is 9 W lower than the i5's 15 W, which makes it suitable for low-power embedded designs, fanless systems, or battery-powered devices where thermal and power budgets are tight. The Atom also has a larger per-core L1 cache (96 KB versus 80 KB) and a larger shared L2 (2 MB versus 1.25 MB per core), though these do not translate into better scores in the recorded data. The Atom's launch MSRP of $42 indicates a low-cost positioning, but the database does not record a similar price for the i5, so no direct cost comparison is possible.

The Atom's Passmark results, while not head-to-head against the i5, show some niche strengths. Its data compression score of 20820 is notable, and its integer math score of 6517 and floating point math score of 4303 suggest it can handle basic compute tasks, but these numbers do not appear in the head-to-head table. The Atom's single-thread Passmark score of 1317 is close to its average benchmark score of 2811, which indicates that its performance profile is dominated by single-threaded and light integer workloads. The i5-1335UE, by contrast, has no recorded Passmark data, so any comparison in those specific tests is impossible from the database.

In summary, the i5-1335UE is the performance winner in every measured category, while the Atom x7211RE is the lower-power option with a lower launch MSRP. The choice depends entirely on whether power draw and cost or raw performance is the priority, and the data strongly favors the i5 for any performance-sensitive use case.
