Intel Core i5-3475S vs Intel Pentium 6805 Comparison

Where Each One Wins

The benchmark results split cleanly along workload type, and the data is unambiguous: the Intel Pentium 6805 wins every recorded benchmark against the Intel Core i5-3475S. Across six head-to-head Cinebench tests, the Pentium 6805 takes all six wins. The Core i5-3475S does not secure a single victory in any of the compared tests.

For multi-threaded workloads, the Pentium 6805 leads consistently. In Cinebench R23 multi-core, it scores 3801 versus 3685 for the i5-3475S, a 3.1% advantage. The same pattern appears in Cinebench R20 multi-core, where the Pentium scores 1596 against 1547, a 3.2% lead, and in Cinebench R15 multi-core, where it posts 383 versus 371, also a 3.2% edge. This is notable because the i5-3475S has four physical cores while the Pentium has only two, yet the Pentium still manages to outpace it in every multi-core test.

Single-threaded performance also favors the Pentium 6805. Cinebench R23 single-core shows 536 versus 520, a 3.1% lead. Cinebench R20 single-core shows 225 versus 218, a 3.2% lead. Cinebench R15 single-core shows 54 versus 52, a 3.8% lead. The single-core margins are slightly larger than the multi-core margins in R15, indicating that the Pentium's architectural efficiency carries over into lightly threaded tasks.

The overall average benchmark score reinforces this picture. The Pentium 6805 averages 1099 across its recorded benchmarks, while the i5-3475S averages 1091. The Pentium also sits at the 31st percentile of all CPUs, one point higher than the i5-3475S's 30th percentile. In the database's nearest-rival comparisons, the Pentium 6805 is essentially tied with the Intel Core i5-3450S (both at 1099 average score), while the i5-3475S is tied with the Intel Pentium Gold G5400 (both at 1091). Neither chip is a top performer in the current database, but the Pentium holds a small, consistent edge everywhere.

Architecture Differences

The two processors come from different Intel design eras, and those differences explain the benchmark results. The Pentium 6805 uses the Ice Lake architecture built on Ice Lake-Y, fabricated on a 10 nm process. The Core i5-3475S uses the Ivy Bridge architecture on a 22 nm process. The process node advantage is significant: 10 nm versus 22 nm allows the Pentium to achieve competitive performance with far lower power consumption.

Core counts differ sharply. The Pentium 6805 has 2 cores and 4 threads, while the Core i5-3475S has 4 cores and 4 threads. The i5-3475S has double the physical cores, yet it still loses in multi-core Cinebench tests. This indicates that per-core efficiency in the Pentium's newer architecture more than compensates for the core count disadvantage. The i5-3475S lacks Hyper-Threading, so its thread count matches its core count at four. The Pentium's two cores each support two threads, giving it four threads as well.

Cache hierarchies also differ. The Pentium 6805 has 80 KB of L1 cache per core and 256 KB of L2 per core, with 4 MB of shared L3. The Core i5-3475S has 64 KB of L1 per core and 256 KB of L2 per core, with 6 MB of shared L3. The i5-3475S has more total L3 cache, but the Pentium has larger L1 per core, which can help with frequently accessed data.

Memory support diverges as well. The Pentium 6805 supports DDR4 memory with dual-channel operation and a memory bandwidth of 51.2 GB/s. The Core i5-3475S supports DDR3 memory with dual-channel operation, and the database records no memory bandwidth figure for it. The integrated graphics differ: the Pentium has UHD Graphics (32EU), while the i5-3475S has Intel HD 4000.

The socket and market positioning are completely different. The Pentium 6805 uses Intel BGA 1526, is a mobile part, and was released on 2020-09-30. The Core i5-3475S uses Intel Socket 1155, is a desktop part, and was released on 2012-05-31. The Pentium is marked end-of-life in production status, while the i5-3475S has no recorded production status. The Pentium's TDP is 15 watts, while the i5-3475S is rated at 65 watts. Both have PCIe Gen 3, but the i5-3475S specifies 16 lanes (CPU only), while the Pentium simply lists Gen 3.

Head-to-Head Benchmarks

The largest percentage win for the Pentium 6805 comes in Cinebench R15 single-core, where it scores 54 against 52, a 3.8% advantage. This is the only head-to-head test where the margin exceeds 3.5%. The remaining five tests cluster tightly between 3.1% and 3.2%.

In Cinebench R15 multi-core, the Pentium scores 383 against 371, a 3.2% delta. In Cinebench R20 multi-core, it scores 1596 against 1547, also a 3.2% delta. In Cinebench R20 single-core, it scores 225 against 218, again a 3.2% delta. The two R23 tests both show a 3.1% delta: multi-core at 3801 versus 3685, and single-core at 536 versus 520.

These margins are small in absolute terms, but they are consistent across every test. The pattern suggests a uniform performance advantage rather than a workload-specific quirk. The Pentium does not win because of a single favorable benchmark; it wins across all six recorded comparisons. The multi-core results are the most informative, since the i5-3475S enters those tests with twice the physical cores. A 3.1% to 3.2% multi-core lead for a 2-core part over a 4-core part points to a substantial per-core efficiency gap.

The database also records Geekbench results for the i5-3475S only, with a multi-core score of 1731 and a single-core score of 607. The Pentium 6805 has no Geekbench data in the database, so no head-to-head comparison can be made on that test.

The base clock difference is striking: the i5-3475S runs at 2.90 GHz base versus 1100.00 MHz for the Pentium, and boosts to 3.60 GHz versus 3.00 GHz. Despite the much lower clock speed, the Pentium still wins every benchmark. The 15 W TDP versus 65 W TDP further highlights the efficiency gap. The i5-3475S has more transistors (1,400 million versus not recorded for the Pentium) and a larger die (160 mm² versus 123 mm²), but the newer 10 nm process gives the Pentium the performance edge.

Both processors use dual-channel memory, have no ECC support, are not multiplier unlocked, and have 256 KB of L2 cache per core. These shared traits are not listed in the table above.

FAQ

Q: Which processor wins in multi-core performance?

A: The Intel Pentium 6805 wins every multi-core Cinebench test. It leads by 3.2% in R15 (383 versus 371) and R20 (1596 versus 1547), and by 3.1% in R23 (3801 versus 3685).

A: The Intel Pentium 6805 supports DDR4 memory with dual-channel operation and a recorded memory bandwidth of 51.2 GB/s. The Intel Core i5-3475S supports DDR3 memory with dual-channel operation, and no memory bandwidth figure is recorded for it.

The Verdict

The data points to a clear conclusion: the Intel Pentium 6805 is the faster processor in every benchmark category the database records. It wins all six head-to-head Cinebench tests, holds a higher average benchmark score (1099 versus 1091), and ranks one percentile higher among all CPUs. The single-core advantage is most pronounced in Cinebench R15, where it leads by 3.8%, and the multi-core advantage is consistent at around 3.1% to 3.2% across all three Cinebench versions.

The Core i5-3475S offers more physical cores, a higher base clock (2.90 GHz versus 1100.00 MHz), a higher boost clock (3.60 GHz versus 3.00 GHz), and more L3 cache (6 MB versus 4 MB). None of these advantages translate into benchmark wins. The Pentium's 10 nm Ice Lake architecture, larger per-core L1 cache, DDR4 memory support, and higher memory bandwidth combine to overcome the raw specification disadvantages.

For users choosing between these two, the decision depends on context. If the workload is rendering, encoding, or any multi-threaded task covered by the Cinebench suite, the Pentium 6805 is the stronger pick despite having fewer cores. If the workload is single-threaded, the Pentium also wins, with margins between 3.1% and 3.8%. The i5-3475S offers no benchmark-based reason for selection in any of the recorded tests.

The Pentium 6805 also presents a major efficiency advantage at 15 W versus 65 W TDP, which matters for mobile or thermally constrained systems. The i5-3475S is a desktop part on Socket 1155 with DDR3 memory, while the Pentium is a mobile part on Intel BGA 1526 with DDR4 memory. The platform differences are substantial, and the recorded data shows the newer, lower-power mobile chip outperforming the older desktop chip across the board.

Users with an existing Socket 1155 platform and DDR3 memory may find the i5-3475S simpler to integrate, but the benchmark data does not support choosing it on performance grounds. The Pentium 6805 wins every head-to-head comparison in the database, and that is the decisive fact.
