Intel Core i3-5157U vs Intel Pentium G4560T Comparison

Head-to-Head Benchmarks

The recorded data presents a clear split between the two processors. In the Cinebench suite, the Intel Pentium G4560T consistently outperforms the Intel Core i3-5157U across every test. The margin is remarkably uniform, with the Pentium holding a 15.3% advantage in Cinebench R15 multicore (256 vs. 222) and a 15.5% lead in Cinebench R20 multicore (1068 vs. 925). Single-core results follow the same pattern: the G4560T scores 150 in Cinebench R20 single-core versus 130 for the i3-5157U, a 15.4% edge, and 359 versus 311 in Cinebench R23 single-core, again 15.4% ahead.

The Cinebench R23 multicore result reinforces this dominance, with the G4560T posting 2544 against the i3-5157U's 2203, a 15.5% gap. Across all five Cinebench tests, the Pentium wins by roughly the same proportion, suggesting a consistent architectural performance advantage in this workload rather than a test-specific quirk.

The Geekbench results, however, tell a completely different story. Here, the Intel Core i3-5157U is the decisive winner. In Geekbench multicore, the i3 scores 1568 against the Pentium's 1237, a 21.1% lead. The single-core gap is even larger: 778 versus 594, a 23.7% difference in favor of the i3-5157U.

This divergence is striking. The Pentium dominates one benchmark family by 15% while the i3 dominates another by over 20%. The head-to-head tally shows five wins for the G4560T and two for the i3-5157U, but the magnitude of the i3's Geekbench victories means the overall picture is not as one-sided as the win count suggests. The average benchmark score for the G4560T is 887, while the i3-5157U sits just behind at 877, a difference of roughly 1%.

Where Each One Wins

The benchmark data indicates that the Intel Pentium G4560T is the stronger choice for rendering and compute-heavy tasks. All five Cinebench tests, which stress multi-threaded and single-threaded CPU performance in a 3D rendering context, favor the Pentium by a consistent 15% to 15.5%. This makes it the better fit for content creation workflows that rely on Cinebench-style CPU rendering, such as 3D modeling and animation.

In contrast, the Intel Core i3-5157U wins decisively in the Geekbench tests, which measure a broader range of everyday computational tasks including encryption, compression, and memory performance. The i3's 23.7% single-core and 21.1% multi-core leads suggest it provides snappier responsiveness in general productivity applications, browser workloads, and other latency-sensitive software.

The use-case split is therefore straightforward: the Pentium G4560T is optimized for sustained rendering performance, while the i3-5157U excels in general-purpose computing scenarios. The Geekbench results also indicate that the i3 has a higher peak single-thread capability despite its lower base clock, which is likely the result of a more efficient microarchitecture or a more capable memory interface. For users prioritizing rendering, the G4560T is the clear winner; for those prioritizing everyday application speed, the i3-5157U holds the advantage.

Architecture Differences

The two processors come from different Intel microarchitectures and target different market segments. The Intel Pentium G4560T is built on the Kaby Lake architecture, part of the 7th generation of Core processors, and is manufactured on a 14 nm process node. It is a desktop part designed for the Intel Socket 1151 platform. The Intel Core i3-5157U, by contrast, belongs to the Broadwell architecture, specifically the Broadwell-U variant, and is also built on a 14 nm node. However, it is a mobile processor soldered to the Intel BGA 1168 socket.

Both chips feature 2 physical cores and 4 threads, indicating Hyper-Threading support on both. The cache hierarchy is identical: 64 KB of L1 cache per core, 256 KB of L2 cache per core, and 3 MB of shared L3 cache. The process node is the same at 14 nm, and both are manufactured by Intel. However, the i3-5157U has a larger documented die size at 133 mm² with 1,900 million transistors, while the G4560T's die size and transistor count are not recorded in the database.

The integrated graphics differ significantly. The G4560T includes Intel HD 610, a basic entry-level GPU, while the i3-5157U comes with Intel Iris 6100, a more advanced integrated graphics solution. This suggests that the i3 is intended for systems where the integrated GPU may handle more demanding visual tasks, such as video playback or light gaming. The memory support also diverges: the G4560T uses DDR4 memory with a peak bandwidth of 38.4 GB/s, whereas the i3-5157U uses DDR3 with a peak bandwidth of 29.9 GB/s. The PCIe interface differs as well, with the Pentium offering Gen 3 with 16 lanes and the i3 offering Gen 2 with 12 lanes.

Specification Differences

A direct comparison of the recorded specifications highlights several key differences between the two processors. The most obvious is the base clock: the Intel Pentium G4560T runs at 2.90 GHz, while the Intel Core i3-5157U runs at 2.50 GHz. Neither chip has a boost clock, so these are the maximum sustained frequencies.

The thermal design power (TDP) also differs. The G4560T is rated at 35 watts, while the i3-5157U is rated at 28 watts, making the i3 more power-efficient on paper. This aligns with the i3's mobile positioning, where lower power consumption is critical for battery life and thermal management.

The release dates are separated by nearly two years. The G4560T was released on January 2, 2017, while the i3-5157U was released on February 28, 2015. The production status reflects this: the G4560T remains active, while the i3-5157U is end-of-life.

The memory support is another differentiator. The G4560T supports DDR4 memory, while the i3-5157U supports DDR3. The memory bandwidth figures follow, with the Pentium offering 38.4 GB/s versus the i3's 29.9 GB/s. The PCIe configuration also differs, with the G4560T providing Gen 3 with 16 lanes and the i3-5157U providing Gen 2 with 12 lanes.

The integrated graphics are not equivalent: the G4560T has Intel HD 610, while the i3-5157U has Intel Iris 6100. The market segment is a fundamental difference, with the Pentium targeting desktop systems and the i3 targeting mobile platforms. The socket types are incompatible: the G4560T uses Intel Socket 1151, while the i3-5157U uses Intel BGA 1168.

The launch MSRP for the i3-5157U is recorded as $315; the G4560T does not have a launch MSRP in the database. Both processors have locked multipliers and support no ECC memory. The part numbers are SR35T for the Pentium and SR26M for the i3.
