Intel Atom C5315 vs Intel Pentium G4560T Comparison

Head-to-Head Benchmarks

The recorded data shows a remarkably close contest between the Intel Pentium G4560T and the Intel Atom C5315. Across all five shared benchmark tests, the Pentium G4560T emerges as the winner, but the margins are consistently narrow, never exceeding 0.7%. This is not a case of one processor dominating another; rather, it is a statistical tie broken by fractions of a percent.

In Cinebench R15 multi-core, the Pentium G4560T scores 256 against the Atom C5315's 255, a delta of 0.4%. The Cinebench R20 multi-core test shows a similar pattern: 1068 for the Pentium versus 1063 for the Atom, a 0.5% advantage. Single-core results follow the same trend, with the Pentium leading 150 to 149 in Cinebench R20 single-core (0.7% delta) and 359 to 357 in Cinebench R23 single-core (0.6% delta). The largest gap appears in the Cinebench R23 multi-core test, where the Pentium scores 2544 against 2533, still only a 0.4% difference.

What these numbers indicate is that for heavily threaded workloads, the two processors land within noise of each other. The Pentium's 2.90 GHz base clock against the Atom's 2.40 GHz base clock does not translate into a meaningful performance advantage in the database's measurements. The Atom's four cores compensate for its lower clock speed when compared to the Pentium's two cores with four threads. The result is a near dead heat in every metric the database records.

The average benchmark scores reinforce this picture. The Pentium G4560T holds an average score of 887, placing it at the 24th percentile of all CPUs in the database. The Atom C5315 averages 871, sitting at the 23rd percentile. The delta between their averages is roughly 1.8%, which is consistent with the head-to-head results. Both processors occupy the same performance tier, competing with older desktop parts such as the AMD PRO A8-8650B (887 average score, 0% delta from the Pentium) and the Intel Core i3-6100 (888 average score, -0.2% delta from the Pentium). For the Atom, the nearest rivals include the AMD Athlon PRO 3045B (872 average score, -0.1% delta) and the Intel Core i7-3540M (867 average score, 0.5% delta).

Where Each One Wins

The Pentium G4560T wins all five recorded head-to-head benchmarks, but the magnitude of those wins is so small that the practical distinction is minimal. The largest single-core advantage, 0.7% in Cinebench R20, gives the Pentium a slight edge in lightly threaded applications such as older games or single-threaded productivity tools. Its 2.90 GHz base clock, higher than the Atom's 2.40 GHz, directly contributes to this lead. For users running software that relies on one or two cores, the Pentium should feel marginally quicker, though the difference would be imperceptible in real-world use.

The Atom C5315, despite losing every recorded benchmark, has structural advantages that do not appear in these particular tests. It offers four physical cores, whereas the Pentium provides two cores with Hyper-Threading for four threads. In workloads that scale with physical core count, the Atom's architecture may show better consistency, particularly in sustained multi-threaded operations. However, the database's Cinebench results do not reveal any such advantage: the Atom trails by 0.4% in both R15 and R23 multi-core tests.

The Atom also supports ECC memory, a feature entirely absent from the Pentium. This positions the Atom for error-correcting memory configurations in storage servers or network appliances, where data integrity matters more than raw speed. The Pentium, with its integrated Intel HD 610 graphics, can handle display output without a discrete GPU, making it suitable for basic desktop systems or media centers. The Atom has no integrated graphics and requires a separate display adapter, which is typical for its server/workstation market segment.

Architecture Differences

The two processors come from different design philosophies within Intel's lineup. The Pentium G4560T uses the Kaby Lake architecture on a 14 nm process node. It features two cores and four threads, with a base clock of 2.90 GHz and no boost capability. Its cache layout includes 64 KB of L1 per core, 256 KB of L2 per core, and 3 MB of shared L3 cache. The memory interface supports DDR4 in dual-channel mode, providing 38.4 GB/s of bandwidth. The Pentium does not support ECC memory. It connects via Intel Socket 1151 with PCIe Gen 3, offering 16 lanes from the CPU. Integrated Intel HD 610 graphics are present, and the processor targets the desktop market segment. It was released in January 2017 and remains in active production.

The Atom C5315 uses the Tremont architecture, part of the Parker Ridge codename family, on a 10 nm process node. It provides four cores and four threads, with a base clock of 2.40 GHz and no boost capability. The cache hierarchy differs notably: 64 KB of L1 per core and 4.5 MB of L2 per module, with no L3 cache present. The memory interface is identical in specification, supporting DDR4 in dual-channel mode at 38.4 GB/s. The Atom does support ECC memory, a critical distinction. It uses Intel BGA 2106 socket with PCIe Gen 3, but only 8 lanes from the CPU. There is no integrated graphics. The Atom targets the server/workstation segment and was released in June 2022. It remains in active production with a launch MSRP of $213.

The process node difference, 14 nm versus 10 nm, suggests the Atom should have efficiency advantages, but the power draw figures tell a different story. The Pentium has a 35 W TDP, while the Atom has a 38 W TDP. The Atom's four cores at a lower clock speed consume slightly more power than the Pentium's two cores at a higher clock speed. This is an unusual result for a newer, denser process node, but the database records these figures without interpretation.

FAQ

Q: Which processor has a higher clock speed?

A: The Intel Pentium G4560T has a base clock of 2.90 GHz, while the Intel Atom C5315 has a base clock of 2.40 GHz. Neither processor supports boost clocks.

Q: Do both processors support the same memory type?

A: Yes, both support DDR4 memory in dual-channel mode with 38.4 GB/s of bandwidth. However, the Atom C5315 adds ECC memory support, which the Pentium G4560T lacks.

Q: How many cores and threads does each processor have?

A: The Pentium G4560T has 2 cores and 4 threads. The Atom C5315 has 4 cores and 4 threads. Despite having fewer physical cores, the Pentium's Hyper-Threading brings its thread count equal to the Atom's.

The Verdict

The data presents a clear but nuanced picture. The Intel Pentium G4560T wins every recorded benchmark, but the margins are so small that they fall within measurement tolerance. If a user's decision hinges purely on benchmark scores, the Pentium is the safer choice by a razor-thin margin. Its integrated graphics and lower TDP make it suitable for compact desktop builds or basic office systems where a discrete GPU is unnecessary.

The Intel Atom C5315, while losing all five head-to-head tests, brings two features the Pentium cannot match: ECC memory support and four physical cores. For server or workstation deployments where memory errors are unacceptable, the Atom's ECC capability is decisive. The four-core layout may also provide more predictable multi-threaded performance in containerized or virtualized environments, even if the Cinebench scores do not reflect a measurable advantage.

The 24th percentile ranking for the Pentium versus the 23rd percentile for the Atom places both in the same performance class. Neither processor will impress in demanding modern applications, but both handle light to moderate workloads without issue. The Pentium suits general desktop use with its graphics output and lower power draw. The Atom suits headless server roles where ECC memory and physical core count take precedence over raw speed. The choice comes down to platform requirements, not performance, since the benchmark data shows near parity across the board.
