Intel Core i3-10320

The Intel Core i3-10320 is a 4-core, 8-thread desktop processor in Intel’s Core 10th Gen lineup, built on the Comet Lake architecture and Intel’s 14 nm process. It runs at a 3.80 GHz base clock and a 4.60 GHz boost clock, with a 91 W TDP and support for Intel Socket 1200. Benchmark data places it at the 73rd percentile of all CPUs, with an average benchmark score of 14852, and its nearest rivals all sit within 1.4 percent of that score in either direction.

Benchmark Performance

The i3-10320 produces a consistent set of mid-range competitive scores. In Cinebench R23 it scores 8484 multi-core and 1197 single-core; in Cinebench R20 it scores 3563 multi-core and 502 single-core; and in Cinebench R15 it scores 855 multi-core and 120 single-core. PassMark results show a multithread score of 9982, a single-thread score of 2841, integer math at 31071, floating point math at 19483, extended instructions at 9284, data compression at 140255, data encryption at 3458, physics at 689, random string sorting at 17821, and find prime numbers at 32.

Against its nearest rivals by average score, the i3-10320 trails the Intel Core i7-9750H by 0.2 percent, trails the AMD EPYC 74F3 by 0.4 percent, leads the Intel Core i5-9500 by 1.1 percent, and trails the Intel Core i3-1315U by 1.4 percent. These deltaPct values are small, meaning the i3-10320 is effectively in the same overall performance band as all four listed rivals. The average benchmark gap is not a large all-around deficit but rather a narrow margin determined by workload-specific tests.

The PassMark sub-scores reveal a distinct profile. Integer math and data compression are the strongest contributors, while find prime numbers and physics are much lower. That pattern suggests the processor handles general data processing and compression-heavy tasks better than tasks with extreme parallel math requirements. The Cinebench scores confirm a balanced single-core/multi-core split: none of the results is dramatically out of line with the others, and the overall average of 14852 reflects a part that sits comfortably near the 73rd percentile.

Power and Thermals

The i3-10320 carries a 91 W TDP, which is the thermal design point reported for the processor. That TDP class, combined with a 14 nm process and a 4.60 GHz boost clock, means the cooling solution needs to be selected for a 91 W part. The data does not include measured temperatures, cooler test results, or power draw under load, so the only quantitative thermal guidance is the TDP itself.

The base clock of 3.80 GHz and boost clock of 4.60 GHz define the operating range, but the fact pack records no sustained clock behavior. In multithreaded loads, the Cinebench R23 multi-core score of 8484 indicates the processor can sustain meaningful work across its 8 threads, but the exact thermal impact of that workload is not listed. Users should treat the 91 W TDP as the relevant thermal target for cooler selection.

Who Should Consider It

The i3-10320 is suited to desktop users who need 4 cores and 8 threads on an Intel Socket 1200 platform and do not require ECC memory. The PassMark single-thread score of 2841 and Cinebench R23 single-core score of 1197 point to responsive performance in lightly threaded office and productivity workloads. The data does not list a GPU benchmark, but the integrated UHD Graphics 630 is available for display output, and the CPU-side single-thread scores are the relevant metric for gaming workloads that are sensitive to single-core speed.

For content creation, the multi-threaded results are the main evidence: Cinebench R23 multi-core 8484, Cinebench R20 multi-core 3563, Cinebench R15 multi-core 855, and PassMark multithread 9982. These scores make the i3-10320 a reasonable option for occasional rendering or batch tasks that scale across 8 threads. The PassMark data compression score of 140255 and random string sorting score of 17821 indicate that file compression and data sorting workloads should run well. The low find prime numbers score of 32 and physics score of 689 suggest it is not the right fit for heavily parallel math workloads that can fully use a higher-core-count processor.

How It Compares

Intel Core i7-9750H:

The Intel Core i7-9750H has an average score of 14877, and the i3-10320 is 0.2 percent behind. In benchmark terms, the two are effectively tied.

AMD EPYC 74F3:

The AMD EPYC 74F3 averages 14915, and the i3-10320 trails by 0.4 percent. The average score gap is under one percent, so the data treats them as nearly equivalent.

Intel Core i5-9500:

The Intel Core i5-9500 averages 14697, and the i3-10320 is 1.1 percent ahead. This is the rival the i3-10320 leads by the largest margin in the nearestRivals data.

Intel Core i3-1315U:

The Intel Core i3-1315U averages 15059, and the i3-10320 trails by 1.4 percent. This is the largest deltaPct among the listed rivals, but it remains a small overall benchmark gap.

Single-Thread vs Multi-Thread Behavior

The Cinebench results show a clear split: R15 single-core 120 and multi-core 855, R20 single-core 502 and multi-core 3563, and R23 single-core 1197 and multi-core 8484. PassMark reports single-thread at 2841 and multithread at 9982. The multi-thread scores are substantially larger than the single-core scores, which is expected for a processor with 8 threads across 4 cores.

The single-thread results indicate that latency-sensitive applications can benefit from the 4.60 GHz boost clock. The integer math score of 31071 and floating point math score of 19483 add further detail: integer-heavy work scores higher than floating-point-heavy work. The data compression score of 140255 and random string sorting score of 17821 are high contributors, while encryption at 3458 is a smaller portion of the overall PassMark result.

For real workloads, this behavior means a mix of outcomes. Single-threaded applications should see responsive performance, while multithreaded applications such as rendering, encoding, and batch processing can use the 8 threads to improve throughput. The data does not show an extreme gap between single-thread and multi-thread capability; instead, the i3-10320 offers balanced behavior with a slight emphasis on integer and data-oriented tasks.
