Intel Core i7-3537U vs Intel Pentium Silver J5005 Comparison

Head-to-Head Benchmarks

The benchmark data presents a decisive sweep in favor of the Intel Pentium Silver J5005 across every recorded Cinebench test. The database records five head-to-head wins for the Pentium Silver, with zero wins for the Core i7-3537U. This is not a close contest by any metric.

In Cinebench R15 multicore, the Pentium Silver J5005 scores 268 against the Core i7-3537U’s 201. That is a 33.3% advantage, a substantial gap that suggests the newer architecture handles sustained multi-threaded loads far more effectively. The single-core results tell a similar story. In Cinebench R20 single-core, the Pentium Silver posts 157 versus 118 for the Core i7-3537U, again a 33.1% delta. The consistency of the margin across both single- and multi-threaded tests is striking: every recorded delta falls between 33% and 33.3%.

Cinebench R23 multicore shows the Pentium Silver at 2660 against 1998 for the Core i7-3537U, a 33.1% lead. Single-core R23 follows the pattern, with 375 versus 282, a 33% difference. The near-identical percentage gains across generations of the Cinebench suite indicate that the performance advantage is not workload-specific but rather a broad architectural improvement.

When placed against the broader field, both processors sit at the 21st percentile of all CPUs in the database. Their average benchmark scores are close: 776 for the Pentium Silver J5005 and 766 for the Core i7-3537U. The Pentium Silver’s nearest rivals include the AMD Athlon X4 760K, which scores 777 and trails by 0.1%, and the Intel Pentium G4520 at 778, which leads by 0.2%. The Core i7-3537U’s nearest rivals include the Intel Core i5-680 at 772, which leads it by 0.8%, and the Intel Core i7-3687U at 773, which leads by 0.9%. These close clustering values show that while the two CPUs are nearly indistinguishable in aggregate database ranking, the direct head-to-head Cinebench measurements favor the Pentium Silver clearly.

The only benchmark where the Core i7-3537U has recorded data that the Pentium Silver lacks is Geekbench. The Core i7-3537U scores 1269 multicore and 658 single-core in Geekbench. Since no Geekbench result exists for the Pentium Silver J5005 in the database, no direct comparison can be made on that test. The available Cinebench data, however, is comprehensive and unambiguous.

FAQ

Q: Which CPU wins more head-to-head benchmark comparisons?

A: The Intel Pentium Silver J5005 wins all five recorded head-to-head comparisons. The Intel Core i7-3537U wins none of them.

Q: How large is the performance difference in multi-core workloads?

A: In Cinebench R20 multicore, the Pentium Silver J5005 scores 1117 versus 839 for the Core i7-3537U, a 33.1% advantage. In Cinebench R23 multicore, the Pentium Silver scores 2660 versus 1998, also a 33.1% lead.

Q: Does the Core i7-3537U have any advantage in single-core tests?

A: No. The Pentium Silver J5005 leads in every recorded single-core test. In Cinebench R20 single-core, it scores 157 against 118, and in Cinebench R23 single-core, it scores 375 against 282. Both are approximately 33% advantages.

Q: How do the two CPUs compare in overall database ranking?

A: Both sit at the 21st percentile of all CPUs. The Pentium Silver J5005 has an average benchmark score of 776, while the Core i7-3537U averages 766.

Q: Is the Core i7-3537U competitive in any benchmark category?

A: The only category where it has data the Pentium Silver lacks is Geekbench, where it scores 1269 multicore and 658 single-core. Without a corresponding Pentium Silver Geekbench result, no head-to-head conclusion is possible for that test.

Architecture Differences

The two processors come from different eras and different design philosophies. The Intel Pentium Silver J5005 uses the Goldmont Plus architecture, part of the Gemini Lake family, built on a 14 nm process. The Intel Core i7-3537U uses the Ivy Bridge architecture, built on a 22 nm process. The newer 14 nm node gives the Pentium Silver a transistor-density advantage on paper, though the database does not record transistor counts for either chip.

Core configuration differs sharply. The Pentium Silver J5005 has 4 physical cores and 4 threads. The Core i7-3537U has only 2 physical cores but uses Hyper-Threading to reach 4 threads. This explains part of the Pentium Silver’s multi-core lead: it has twice as many physical execution units, even though both present 4 threads to the operating system.

Cache layouts reflect the architectural split. The Pentium Silver J5005 allocates 56 KB of L1 cache per core and shares a 4 MB L2 cache across all cores. It has no L3 cache. The Core i7-3537U has 64 KB of L1 per core, 256 KB of L2 per core, and a shared 4 MB L3 cache. The older chip therefore relies on a larger per-core L2 and a dedicated L3 tier, while the newer chip consolidates its secondary cache into a single shared pool.

Memory support also diverges. The Pentium Silver J5005 supports DDR4 memory on a dual-channel bus with a recorded bandwidth of 38.4 GB/s. The Core i7-3537U supports DDR3 memory on a dual-channel bus, but the database records no bandwidth figure for it. Neither chip supports ECC memory.

Integrated graphics differ as well. The Pentium Silver J5005 carries UHD Graphics 605, while the Core i7-3537U carries Intel HD 4000. Both are integrated solutions aimed at mobile use, but the UHD Graphics 605 is the newer generation.

The Pentium Silver J5005 has a PCIe implementation listed as Gen 2 with 6 lanes from the CPU. The Core i7-3537U has no PCIe data recorded in the database. Both processors use Intel BGA sockets, but different ones: the Pentium Silver uses BGA 1090, while the Core i7-3537U uses BGA 1023. Neither is socketed for user upgrades, which is typical for mobile parts.

Clock speeds favor the Core i7-3537U on paper. It has a base clock of 2.00 GHz and a boost clock of 3.20 GHz, compared to the Pentium Silver’s 1.50 GHz base and 2.80 GHz boost. Despite the higher clocks, the Core i7-3537U loses every Cinebench comparison. This indicates that IPC (instructions per clock) improvements in the Goldmont Plus architecture, combined with the extra physical cores, more than offset the clock disadvantage.

Thermal design power also differs. The Pentium Silver J5005 is rated at 10 W TDP, while the Core i7-3537U is rated at 17 W TDP. The Pentium Silver delivers higher benchmark scores while drawing less power, at least according to the TDP ratings in the database.

The release dates place the two chips far apart. The Core i7-3537U was released in January 2013, while the Pentium Silver J5005 was released in December 2017. That nearly five-year gap explains the architectural generational leap.

The Verdict

The data points to one clear conclusion: the Intel Pentium Silver J5005 is the superior processor in every recorded benchmark comparison. It wins all five head-to-head Cinebench tests with margins of approximately 33%. It achieves this while also carrying a lower TDP of 10 W versus 17 W for the Core i7-3537U.

Users who prioritize multi-threaded workloads, such as compiling, rendering, or running multiple applications simultaneously, should choose the Pentium Silver J5005. Its 4 physical cores and 33.1% lead in Cinebench R20 multicore make it the stronger option. Users who prioritize single-threaded responsiveness will also find the Pentium Silver ahead, with a 33.1% lead in Cinebench R20 single-core.

The Core i7-3537U retains one niche: it is the only one of the two with recorded Geekbench scores, at 1269 multicore and 658 single-core. But since the Pentium Silver has no Geekbench result in the database, this cannot be interpreted as a comparative advantage.

The launch MSRP of the Pentium Silver J5005 was $161. The Core i7-3537U has no recorded launch MSRP in the database.

For any application covered by the Cinebench suite, the Pentium Silver J5005 is the clear winner. The architecture is newer, the core count is higher, the thermal envelope is lower, and the benchmark results are consistently better. The Core i7-3537U belongs to an older generation and its performance ceiling is simply lower across the board.

The Pentium Silver J5005 offers a smaller die, a smaller process node, more physical cores, lower TDP, and newer memory support. The Core i7-3537U offers higher clock speeds, a larger L1 and per-core L2 cache, and an L3 cache tier. In benchmark results, the Pentium Silver’s architectural advantages outweigh the Core i7-3537U’s higher clocks and larger legacy cache hierarchy.
