CPU Comparison

Head-to-Head Benchmarks

The benchmark data tells a remarkably one-sided story. The Intel Core i3-12100F wins 17 of the 19 direct comparisons, and the margins are not subtle. In Cinebench R23 multi-core, the i3-12100F scores 11,860 against the i5-8500’s 8,079, a 46.8% advantage. That gap holds almost exactly across the entire Cinebench suite: R15 multi-core shows 1,195 versus 814 (46.8% ahead), and R20 multi-core shows 4,981 versus 3,393 (46.8% ahead). The consistency of that 46.8% figure across three different Cinebench versions suggests a fundamental throughput advantage, not a workload-specific quirk.

Single-core performance is where the generational leap becomes most obvious. The i3-12100F posts 1,674 in Cinebench R23 single-core versus 1,140 for the i5-8500, again a 46.8% lead. Geekbench single-core shows a 44% gap (1,932 versus 1,342). The i3’s 4.30 GHz boost clock versus 4.10 GHz on the i5 explains only part of this; the architecture efficiency matters more.

The largest single delta comes in PassMark data encryption, where the i3-12100F scores 8,071 versus 3,027, a staggering 166.6% advantage. That is not a typo; the newer chip more than doubles the older one’s encryption throughput. Integer math also shows a massive gap: 40,978 versus 26,551, a 54.3% lead. Floating-point math follows at 42.2% ahead (31,977 versus 22,489). Physics simulation in PassMark shows a 56.8% advantage (985 versus 628).

The i5-8500 does manage two wins, both narrow. In PassMark extended instructions, it scores 11,480 against the i3-12100F’s 10,842, a 5.6% edge. Random string sorting also goes to the i5: 16,294 versus 15,809, a 3% advantage. These are the only two benchmarks where the older six-core chip outperforms the newer four-core part, and neither is a mainstream productivity or gaming workload.

Data compression shows a 19.1% win for the i3 (160,452 versus 134,673), while prime number finding shows a 66.7% advantage (60 versus 36). Multi-threaded PassMark shows a 47% lead (14,015 versus 9,532). The overall average benchmark scores reflect this: the i3-12100F sits at 13,494 average, the i5-8500 at 13,142, a smaller gap than individual tests suggest, since the i5’s two wins and several close results pull its average up.

Where Each One Wins

Looking strictly at the benchmark data, the Intel Core i3-12100F is the clear winner in almost every category that matters for modern desktop use. Rendering workloads, represented by Cinebench R15, R20, and R23, all show the i3 ahead by roughly 47% in both single and multi-threaded tests. That makes it the better choice for any CPU-bound creative work like video encoding, 3D rendering, or photo batch processing, even though it has fewer physical cores.

General productivity also favors the i3 decisively. Geekbench multi-core shows a 52.6% lead (7,252 versus 4,752), and integer math, which underpins office applications, compilation, and spreadsheet work, shows a 54.3% advantage. The encryption test’s 166.6% lead suggests the i3 handles secure connections, VPN traffic, and file encryption far more efficiently. Physics simulation, relevant to lightweight engineering tools and some games, also goes to the i3 by 56.8%.

The i5-8500’s two wins are narrow and niche. Extended instructions (11,480 versus 10,842) suggests it handles certain SIMD-heavy workloads slightly better, though the 5.6% margin is small. Random string sorting (16,294 versus 15,809) is a 3% edge, relevant to database-style operations but far from a compelling reason to choose the older chip.

The i5-8500 does have one structural advantage not captured in the benchmark scores: it includes integrated graphics (UHD Graphics 630), while the i3-12100F has none. If the system needs a display output without a discrete GPU, the i5 is the only one that can work out of the box. The i3 requires a separate graphics card for any visual output.

Architecture Differences

The two processors come from different eras and different design philosophies. The i3-12100F uses Alder Lake architecture on Intel’s 10 nm process, while the i5-8500 uses Coffee Lake on 14 nm. That process shrink is a major factor in the performance gap, the i3 achieves higher performance while consuming less power, with a 58 W TDP against the i5’s 65 W.

Core counts tell an interesting story. The i5-8500 has six physical cores but only six threads, no hyperthreading. The i3-12100F has four physical cores and eight threads via hyperthreading. Despite two fewer physical cores, the i3’s superior instruction-per-clock efficiency and SMT more than compensate. The data shows this clearly: multi-threaded Cinebench R23 is 46.8% faster on the i3 despite the i5 having 50% more physical cores.

Cache layouts differ significantly. The i3-12100F uses 80 KB of L1 per core, 1.25 MB of L2 per core, and 12 MB of shared L3. The i5-8500 uses 64 KB of L1 per core, 256 KB of L2 per core, and 9 MB of shared L3. The i3’s much larger per-core L2 is particularly notable, 1.25 MB versus 256 KB is a fivefold difference that helps with repeated data access patterns.

Memory support also diverges. The i3-12100F supports both DDR4 and DDR5, while the i5-8500 is limited to DDR4. Both use dual-channel memory buses, but the i5 lists a specific memory bandwidth figure of 42.7 GB/s while the i3 does not list one. PCIe connectivity differs too: the i3 offers Gen 5 with 16 CPU lanes, while the i5 sticks with Gen 3 and 16 lanes.

Sockets are incompatible. The i3-12100F uses Intel Socket 1700, the i5-8500 uses Intel Socket 1151. A motherboard upgrade is mandatory if moving between these two. The die sizes are similar, 163 mm² for the i3, 154 mm² for the i5, though the i3 packs more transistors into a slightly larger area despite the smaller process node.

The i5-8500 has been marked end-of-life, while the i3-12100F remains active in production. The i5 launched in February 2018; the i3’s release date is not listed, but its 12th Gen series places it several generations newer.

The Verdict

The data supports only one conclusion for most buyers: the Intel Core i3-12100F is the superior processor in nearly every measurable way. It is 46.8% faster in every Cinebench version, 44-52.6% faster in Geekbench, and 41.1% faster in PassMark single-thread. It wins 17 of 19 head-to-head tests, including all the ones that matter for gaming, rendering, and general productivity.

The i5-8500’s only meaningful advantages are its integrated GPU and its two narrow benchmark wins. If the build requires integrated graphics, for a basic office PC, a home theater setup, or a temporary system without a discrete card, the i5-8500 is the only option of the two. Its 6-core/6-thread configuration also gives it raw core count, but the benchmark data shows that raw count does not translate into real performance against the newer architecture.

Buyers on a tight platform budget should note the socket difference. The i3-12100F requires a Socket 1700 motherboard, which is newer and may carry a premium. The i5-8500’s Socket 1151 platform is older and potentially cheaper used. However, the i5-8500 is end-of-life, meaning no new units and limited long-term support. The i3 remains in active production.

The i3-12100F also carries a launch MSRP of $97, compared to the i5-8500’s launch MSRP of $192. Both processors have locked multipliers, so overclocking is not an option for either.

For anyone building a new system, the i3-12100F is the obvious choice. For anyone upgrading an existing Socket 1151 system, the i5-8500 might be a drop-in option, but the data shows it is significantly slower than even the budget i3 from a newer generation.
