Intel Core i3-7300T

The Intel Core i3-7300T is a dual-core desktop processor from the Kaby Lake generation, built on Intel's 14 nm process. It operates at a fixed 3.50 GHz base clock with no boost capability, and its benchmark data places it in the 34th percentile of all CPUs tested, indicating a modest entry-level standing in the current performance landscape.

Benchmark Performance

The Core i3-7300T’s average benchmark score of 1213 places it in a tightly clustered group of processors, where the difference between it and its nearest rivals is measured in fractions of a percent. The data shows a near-perfect statistical tie with the Intel Core i5-3570, which scores 1214, a delta of -0.1%. This means the i3-7300T is effectively identical in aggregate performance to that older quad-core i5, despite having half the physical cores but benefiting from Hyper-Threading.

In multi-core workloads, the chip delivers a Cinebench R23 score of 3526, which is more than double its Cinebench R15 result of 355. This scaling is expected given the different rendering engines, but the R23 number reinforces that the dual-core design with four threads is the primary constraint. The single-core Cinebench R23 score of 497, paired with a R20 single-core score of 208, shows that per-thread performance is competitive for its era, but the lack of a boost clock keeps it from pushing higher.

The deltas against its nearest rivals are negligible: it trails the AMD Ryzen Embedded R1606G by 0.1% (1215 vs 1213 score) and the Intel Xeon E5-1607 v3 by 0.4% (1217 vs 1213). However, those margins are within statistical noise. The more meaningful observation is the gap to the Intel Core i7-3612QE, where the i3-7300T leads by 0.1% (1213 vs 1211). In practical terms, the benchmark results indicate that the i3-7300T is a consistent performer that neither excels nor falters against its direct competition, sitting firmly in the lower-middle tier of the overall CPU distribution.

How It Compares

Intel Core i5-3570: The i3-7300T matches the i5-3570 almost exactly, with a delta of -0.1%. This is notable because the i5-3570 is a quad-core Ivy Bridge part, while the i3-7300T uses two cores with four threads. The newer Kaby Lake architecture and higher clock speed of 3.50 GHz compensate for the core deficit, resulting in a dead heat in aggregate benchmarks. For a user upgrading from that generation, the i3-7300T offers comparable throughput but with lower power demands.

Intel Core i7-3612QE: The i3-7300T edges out this mobile quad-core i7 by 0.1%. The i7-3612QE is constrained by its laptop-oriented design, likely running at lower clocks to fit thermal envelopes. The i3-7300T’s desktop positioning and higher base clock allow it to narrowly outperform it in mixed workloads, despite the i7 having four physical cores. This result underscores how clock speed can offset core count in older generations.

AMD Ryzen Embedded R1606G: The i3-7300T trails this AMD part by 0.1%. The R1606G is a modern embedded processor with 14 nm process technology, similar to the i3-7300T, but the delta is negligible. The benchmark data shows they are functionally interchangeable in performance, though the AMD part includes a different feature set for embedded applications. For a desktop user, the i3-7300T holds its own against this newer rival.

Intel Xeon E5-1607 v3: The i3-7300T falls 0.4% behind this Xeon, which is a quad-core Haswell-EP workstation chip. The Xeon likely has a higher base clock and more cache, but the i3-7300T’s architectural advantages narrow the gap to a rounding error. This comparison shows that the i3-7300T can keep pace with older professional-grade silicon in general-purpose tasks, though the Xeon may excel in other areas not captured by these aggregate scores.

Platform and Compatibility

The Core i3-7300T uses the Intel Socket 1151, which places it in a well-established desktop ecosystem. It supports DDR4 memory in a dual-channel configuration, yielding a memory bandwidth of 38.4 GB/s. This is a standard setup for its generation, and the lack of ECC memory support confirms its consumer-oriented positioning. The processor provides 16 PCIe Gen 3 lanes from the CPU, which is sufficient for a single discrete graphics card or a couple of NVMe drives, though expansion is limited compared to higher-tier platforms.

The integrated graphics are Intel HD 630, which means the chip can run a basic display output without a dedicated GPU. The production status is listed as Active, indicating that it remains available for new systems or replacements. The processor is not multiplier-unlocked, so overclocking is not an option; users are locked to the 3.50 GHz base clock. The part number is SR35M, and the release date is January 2017, making it a Kaby Lake-era component that fits into any Socket 1151 board with the appropriate BIOS support.

Upgrade path considerations are straightforward: since it is a dual-core part, users on this platform can move to higher-core-count Kaby Lake or even Coffee Lake chips, provided the motherboard supports them. However, the lack of a boost clock and the locked multiplier mean the i3-7300T is a baseline offering. The 14 nm process node is shared with many other Intel parts of that era, so thermal and power characteristics are predictable. The dual-channel memory bus is fully utilized, and the 16 PCIe lanes are typical for a mainstream desktop chip, allowing for standard configurations without unusual constraints.

FAQ

Q: How does the Core i3-7300T perform in single-threaded workloads?

A: The Cinebench R23 single-core score is 497, and the R20 single-core score is 208. These results, combined with the fixed 3.50 GHz clock, show that single-thread performance is respectable for a dual-core part from its generation, but it does not benefit from any boost clock to push higher.

Q: What is the memory configuration for this processor?

A: It supports DDR4 memory in a dual-channel layout, providing a memory bandwidth of 38.4 GB/s. ECC memory is not supported, so standard consumer DDR4 modules are required.

Q: Can I overclock the Core i3-7300T?

A: No, the multiplier is locked. The processor runs at a fixed 3.50 GHz base clock with no boost capability, so performance is fixed at the factory settings.

Q: Which socket does this CPU use?

A: It uses the Intel Socket 1151, which is compatible with a wide range of motherboards from the Kaby Lake generation. The 16 PCIe Gen 3 lanes are provided by the CPU itself.

Q: How many cores and threads does the i3-7300T have?

A: It has 2 cores and 4 threads, enabled by Hyper-Threading. The L3 cache is 4 MB shared, with 64 KB L1 and 256 KB L2 per core.

Q: Does the processor include integrated graphics?

A: Yes, it features Intel HD 630 integrated graphics, allowing for basic display output without a discrete GPU. This makes it suitable for simple desktop tasks or budget builds.

Power and Thermals

The Core i3-7300T is rated at a 35 W TDP, which classifies it as a low-power desktop processor. This is significantly lower than typical 65 W or 95 W parts, making it an excellent candidate for compact or silent builds. The 14 nm manufacturing process helps achieve this efficiency, and the fixed 3.50 GHz clock without boost means power draw is consistent under load rather than spiking. A capable air cooler with a modest heatsink is sufficient to manage thermals, as the data suggests the chip does not produce excessive heat. The low TDP also implies that it can be used in small-form-factor systems with limited airflow, provided the cooler is rated for at least 35 W. The lack of overclocking further ensures that power consumption remains predictable, so users can select a cooling solution based on the 35 W rating without headroom for manual tuning. For thermally constrained environments, this processor is a sensible choice, trading raw performance for efficiency and low heat output.
