Intel Core i3-7320

The Intel Core i3-7320 is a desktop processor built on Intel's 14 nm Kaby Lake architecture, occupying a modest position in the overall performance landscape with a 34th-percentile ranking among all CPUs. It pairs two physical cores with four threads via Hyper-Threading, runs at a fixed 4.10 GHz base clock with no boost capability, and integrates Intel HD 630 graphics. Its average benchmark score of 1187 places it in the lower-mid tier, directly alongside several older or lower-power parts from both Intel and AMD, as the nearest-rival data shows. The following sections break down the platform, power characteristics, benchmark results, and competitive positioning based exclusively on the supplied facts.

Platform and Compatibility

The Core i3-7320 uses the Intel Socket 1151 interface, which is the standard mounting for mainstream desktop processors of its generation. It is built on the Kaby Lake architecture, a refinement of the earlier Skylake design, and manufactured on Intel's 14 nm process node. The processor is produced by Intel's own foundry, though the die size and transistor count are not specified in the data.

Memory support is limited to DDR4, operating on a dual-channel bus. The memory bandwidth is rated at 38.4 GB/s, a figure that reflects the theoretical peak transfer rate for the integrated memory controller. The processor does not support ECC memory, so error-correcting memory modules are not an option for this chip. This is a typical limitation for consumer-oriented desktop parts.

For expansion, the i3-7320 provides PCIe Gen 3 connectivity with 16 lanes available from the CPU itself. This is the standard allocation for a single high-bandwidth graphics card or multiple lower-speed devices, though the exact lane distribution is not detailed. The integrated graphics unit is the Intel HD 630, which provides basic display output and hardware acceleration for media playback, but no dedicated performance tier is specified.

The processor has a locked multiplier, meaning it is not unlocked for overclocking. This is consistent with the i3 branding, which typically targets mainstream users who rely on stock clocks. The part number is SR358, and it was released on January 2, 2017. The production status is listed as "Active," indicating it remains in the current product stack. No launch MSRP is provided, so no pricing information is available.

Upgrade path considerations are not explicitly documented in the fact pack, but the socket 1151 platform historically supports multiple generations of Intel Core processors. However, without additional data, any claims about compatibility with other chips would be speculative. The key takeaway is that this is a dual-core, four-thread desktop CPU with standard DDR4 and PCIe 3.0 support, suitable for basic productivity and light gaming builds.

Power and Thermals

The Core i3-7320 has a thermal design power (TDP) of 51 watts. This figure represents the maximum amount of heat the cooling system must dissipate under sustained load. A 51W TDP is on the lower end for desktop processors, which typically range from 35W for ultra-low-power parts to over 100W for high-end models. Consequently, the i3-7320 does not require an elaborate cooling solution; a standard air cooler with a modest heatsink and fan is sufficient to maintain safe operating temperatures.

Because the TDP is relatively low, the processor is well-suited for small form factor systems where cooling space is limited. It also draws less power than higher-tier chips, which can reduce overall system power consumption, though the exact wattage figures are not provided in the fact pack. The absence of a boost clock means the CPU runs at a constant 4.10 GHz under all conditions, simplifying thermal behavior — there is no transient boost state that could cause temporary spikes in heat output.

The 14 nm process node helps keep power density manageable, but the fact pack does not list any specific thermal or power measurements beyond the TDP. The integrated Intel HD 630 graphics also contributes to the total thermal load, but its individual power draw is not specified. In practice, a 51W TDP places the i3-7320 in the same cooling tier as many other mainstream dual-core and quad-core processors from its era, such as those found in budget desktops and all-in-one systems.

For users planning a build, the TDP class implies that a basic tower cooler or even a compact low-profile cooler will suffice. There is no need for liquid cooling or high-end air towers. The locked multiplier further reduces the need for overkill cooling, as there is no headroom for manual overclocking that would increase heat output. Overall, the thermal profile is straightforward and forgiving.

Benchmark Performance

The benchmark results for the Core i3-7320 come from the Cinebench suite, which measures rendering performance in both single-core and multi-core workloads. In Cinebench R15, the processor scores 413 points in the multicore test and 58 points in the single-core test. The R20 version yields 1724 points multicore and 243 points single-core. The most recent Cinebench R23 results show 4106 points multicore and 579 points single-core. These scores are absolute values, not normalized to any reference.

The average benchmark score across all recorded tests is 1187, which places the i3-7320 at the 34th percentile of all CPUs. This means that approximately two-thirds of all processors in the database outperform it, while one-third are slower. The percentile is a global ranking, so it includes many high-end desktop and server parts. Within the context of its nearest rivals, the i3-7320 is essentially tied with two other processors and slightly behind two more.

Specifically, the Intel Core i5-4460T has an identical average score of 1187, resulting in a delta of 0%. The Intel Core i7-8665UE also scores 1187, again with a 0% delta. The Intel Core i3-1005G1 achieves 1190, which is 0.3% higher than the i3-7320, and the AMD Opteron 6234 posts 1191, also 0.3% higher. These deltas are small enough to be considered within run-to-run variation, meaning the i3-7320 is functionally on par with all four rivals in aggregate performance.

Looking at the individual Cinebench scores, the multicore results show a clear pattern: the i3-7320's two physical cores and four threads deliver a level of throughput that is consistent with other dual-core parts of its generation. The single-core scores are relatively high for the architecture, reflecting the 4.10 GHz base clock, which is above the typical 3.0–3.5 GHz range for many competing processors. However, the lack of a boost clock means that single-core performance is fixed, whereas rivals with boost capabilities may dynamically exceed their base frequencies.

The R23 multicore score of 4106 is particularly informative. For a dual-core processor, this is a solid result, but it falls well short of quad-core and higher parts. The R23 single-core score of 579 is competitive with many modern low-power chips, but again, the absence of turbo means it cannot reach the peaks seen in boost-capable rivals. Overall, the benchmark data indicates that the i3-7320 is a competent entry-level desktop CPU, suitable for everyday tasks and light content creation, but it will struggle in heavily threaded workloads.

How It Compares

The Intel Core i3-7320 sits in a tight cluster of processors with nearly identical average benchmark scores. Its first nearest rival, the Intel Core i5-4460T, matches the i3-7320 exactly with an average score of 1187 and a delta of 0%. The i5-4460T is a lower-clock, lower-TDP variant of the older Haswell generation, so the parity in performance is notable — the i3-7320 achieves the same aggregate score despite having fewer physical cores (2 vs. 4 in the i5-4460T, though the i5-4460T also has 4 threads). This suggests that the i3-7320's higher clock speed compensates for its core deficit in the benchmarks recorded.

The Intel Core i7-8665UE also scores 1187, again a 0% delta. This is a mobile processor designed for thin-and-light laptops, with a much lower TDP and a different architecture (Whiskey Lake). The fact that a desktop dual-core and a mobile quad-core (the i7-8665UE has 4 cores and 8 threads) land on the same average score underscores how the i3-7320's fixed high clock benefits single-threaded workloads, while the i7-8665UE's extra cores help in multicore scenarios. The overall parity means a user would see similar aggregate performance, but the distribution across workloads differs.

The Intel Core i3-1005G1 is a newer Ice Lake mobile part, scoring 1190 — a 0.3% advantage over the i3-7320. This is a negligible margin, but it is notably the i3-1005G1 is a 10 nm processor with a lower base clock (1.2 GHz) but a much higher boost (up to 3.4 GHz). Its superior average score likely comes from the boost capability, which the i3-7320 lacks. Still, the difference is under a single percentage point, so the i3-7320 remains competitive against this modern low-power chip.

Finally, the AMD Opteron 6234, a server-oriented processor from 2012, scores 1191, also 0.3% ahead of the i3-7320. The Opteron has many more cores (8 or 12, depending on configuration, though not specified here), but its much lower clock speed and older architecture bring its aggregate performance down to the same level. This comparison highlights the i3-7320's efficiency: a dual-core desktop chip can match a multi-core server part in these specific benchmarks, thanks to its high frequency and modern IPC. Overall, the i3-7320 is positioned as a solid entry-level option that holds its own against a diverse set of rivals, none of which can claim a meaningful performance advantage.
