Intel Core i3-9100HL vs Intel Core i5-2310 Comparison

The Intel Core i5-2310 and Intel Core i3-9100HL are two very different processors that land in nearly the same performance tier. The data shows a striking pattern: across every benchmark in the comparison set, the older Sandy Bridge part edges out the newer Coffee Lake chip by a razor-thin margin. The i5-2310 wins all five head-to-head tests, yet the largest delta between them is just 1%. This is not a case of generational superiority; it is a case of near-perfect performance parity between two CPUs separated by eight years of architecture.

Head-to-Head Benchmarks

The benchmark results paint a picture of extreme closeness. In Cinebench R15 multi-core, the i5-2310 scores 314 against the i3-9100HL's 311, a 1% difference. That is the single largest margin of victory in the entire comparison. The story repeats in Cinebench R20 multi-core, where the i5-2310 posts 1309 versus 1299, a 0.8% lead. Single-core performance is equally tight: the i5-2310 scores 184 in Cinebench R20 single-core, just 0.5% ahead of the i3-9100HL's 183. Cinebench R23 multi-core shows the i5-2310 at 3118 against 3094, another 0.8% gap, and single-core R23 ends at 440 versus 436, a 0.9% edge.

What does this mean in practical terms? These deltas are within run-to-run variance for most benchmarking suites. The i5-2310 is technically the winner in all five tests, but the margins are so small that no workload would realistically favor one over the other based on raw compute throughput alone. The average benchmark scores confirm this: the i5-2310 sits at 1073, while the i3-9100HL is at 1065. Both processors occupy the 29th-30th percentile of all CPUs, meaning they are statistically indistinguishable in overall performance. The i5-2310's nearest rivals include the Core i3-4170T and Pentium Gold G6505, both within 0.1% of its average score. The i3-9100HL sits alongside the Xeon W3580 and Core i5-2380P, also within fractions of a percent.

The head-to-head data is unambiguous: five wins for the i5-2310, zero for the i3-9100HL. But the magnitude of those wins, never exceeding 1%, suggests that the architectural and clock-speed differences between these two chips effectively cancel out in Cinebench workloads.

Architecture Differences

The i5-2310 is built on Sandy Bridge, Intel's 32 nm process, with a die size of 216 mm² and 1,160 million transistors. The i3-9100HL uses Coffee Lake on a 14 nm process, with a much smaller die at 126 mm². This is a classic example of process node shrinkage enabling similar performance in a smaller, more efficient package. Both CPUs have four cores and four threads, with identical cache hierarchies: 64 KB of L1 per core, 256 KB of L2 per core, and 6 MB of shared L3.

The clock speeds tell a more complex story. The i5-2310 runs at a 2.90 GHz base clock and boosts to 3.20 GHz. The i3-9100HL has a 1600.00 MHz base clock (1.60 GHz) but boosts to 2.90 GHz. The i5-2310's higher base and boost clocks explain its slight edge in single-core tests. However, the i3-9100HL compensates with a much lower TDP: 25 watts versus 95 watts for the i5-2310. That is a 70-watt difference, making the i3-9100HL dramatically more power-efficient despite delivering nearly identical performance.

Memory support diverges significantly. The i5-2310 uses DDR3 with a dual-channel bus, while the i3-9100HL uses DDR4 with a dual-channel bus and a rated bandwidth of 42.7 GB/s. The i3-9100HL also supports ECC memory, which the i5-2310 does not. Both use PCIe Gen 3 with 16 lanes (CPU only). Integrated graphics differ as well: the i5-2310 has Intel HD 2000, while the i3-9100HL has UHD Graphics 630, a much more capable iGPU. Sockets are incompatible: the i5-2310 uses Intel Socket 1155, and the i3-9100HL uses Intel BGA 1440.

The production status is end-of-life for both. The i5-2310 was released in May 2011, while the i3-9100HL came out in March 2019. The i3-9100HL has a launch MSRP of $225.

FAQ

The i3-9100HL has a launch MSRP of $225, while the i5-2310 has no listed MSRP. Both share four cores, four threads, dual-channel memory bus, PCIe Gen 3 with 16 lanes, and 6 MB of shared L3 cache.

Where Each One Wins

The i5-2310 wins on raw benchmark performance, taking all five head-to-head tests. Its higher base clock of 2.90 GHz and boost of 3.20 GHz give it a slight edge in both single-core and multi-core Cinebench scores. If the workload is purely CPU-bound and power consumption is not a concern, the i5-2310 is the marginally faster part. Its socket, Intel Socket 1155, may also be more accessible for users with existing LGA1155 motherboards.

The i3-9100HL wins on efficiency and platform features. Its 25-watt TDP makes it far more suitable for thermally constrained environments, such as small-form-factor or embedded systems. The DDR4 memory support with 42.7 GB/s bandwidth provides a modern memory interface, and ECC memory support is a critical feature for reliability-sensitive applications like servers or workstations. The UHD Graphics 630 is a substantial upgrade over the HD 2000, enabling better display output and hardware acceleration. The BGA 1440 socket indicates a soldered design, typical of embedded or low-power applications where upgradeability is less important than compactness and reliability.

In terms of market positioning, the data shows both CPUs are end-of-life and sit in the 29th-30th percentile of all CPUs. The i5-2310's average benchmark score of 1073 is just 0.8% higher than the i3-9100HL's 1065. Neither chip has a clear advantage in compute-heavy tasks. The decision between them comes down to platform priorities: the i5-2310 for legacy socket compatibility and a slight performance lead, or the i3-9100HL for power efficiency, modern memory, and ECC support. Benchmark results indicate that raw processing power is not the differentiator here; the surrounding platform is.
