AMD Athlon PRO 3045B vs Intel Pentium G4560T Comparison

Head-to-Head Benchmarks

The benchmark data reveals a clear split between the two processors, with the Intel Pentium G4560T dominating the Cinebench suite while the AMD Athlon PRO 3045B claims victory in Geekbench tests. Across seven recorded benchmarks, the Intel part wins five, the AMD part wins two. This is not a lopsided contest; each CPU has a distinct strength profile.

Starting with Cinebench R15 multi-core, the Pentium G4560T scores 256 against the Athlon PRO 3045B's 237, an 8% advantage. The margin grows slightly in Cinebench R20 multi-core, where Intel leads 1068 to 988, a delta of 8.1%. The same 8.1% gap appears in Cinebench R23 multi-core, with scores of 2544 and 2354 respectively. The consistency of this multi-core margin across three different Cinebench versions suggests a stable architectural advantage rather than a workload-specific quirk.

Single-core Cinebench results follow a similar pattern. In Cinebench R20 single-core, the Pentium G4560T posts 150 versus 139 for the Athlon, a 7.9% lead. Cinebench R23 single-core shows 359 against 332, again an 8.1% edge. The Intel CPU's higher base clock of 2.90 GHz, compared to the AMD part's 2.30 GHz base, likely contributes to this consistent lead, though the Athlon's 3.20 GHz boost clock does not translate into Cinebench single-thread wins.

The Geekbench results flip the narrative entirely. In Geekbench multi-core, the Athlon PRO 3045B scores 1287 against the Pentium's 1237, a 3.9% advantage for AMD. The single-core Geekbench gap is far more dramatic: the AMD part scores 766 versus Intel's 594, a massive 22.5% delta. This is the largest performance difference in either direction across all recorded benchmarks. The Geekbench single-core result stands out as the defining win for the Athlon, nearly quadrupling the magnitude of any Intel victory.

The average benchmark scores reflect this mixed picture. The Pentium G4560T averages 887 across all recorded tests, placing it in the 24th percentile of all CPUs. The Athlon PRO 3045B averages 872, sitting at the 23rd percentile. The 15-point difference in average score is small, and the percentile gap of one point confirms that these are closely matched parts in overall terms. The nearest rival data reinforces this: the Pentium's closest competitor is the AMD PRO A8-8650B at an identical 887 average score with a 0% delta, alongside the Intel Xeon X5550 at 888 (-0.1%) and the Intel Core i3-6100 at 888 (-0.2%). The Athlon's nearest rivals include the Intel Atom C5315 at 871 (0.1% delta) and the Intel Core i3-5157U at 877 (-0.5%). Both CPUs sit in a dense cluster of similarly performing processors, but their win patterns are polar opposites.

The Verdict

The data supports a straightforward recommendation based on workload profile. Users running Cinebench-style multi-threaded rendering tasks should favor the Intel Pentium G4560T. It wins every Cinebench test by roughly 8%, and this margin is consistent across R15, R20, and R23 versions. The Pentium also holds a slight overall average score advantage (887 versus 872), and its 24th percentile ranking edges out the Athlon's 23rd percentile.

The AMD Athlon PRO 3045B is the choice for Geekbench-oriented workloads, particularly single-threaded tasks. Its 22.5% single-core Geekbench lead is substantial, and the 3.9% multi-core Geekbench win shows that AMD's architecture handles that benchmark suite better across the board. The Athlon's 766 single-core Geekbench score is its strongest result, and it suggests that applications relying on single-thread performance in Geekbench-like scenarios will run noticeably better on the AMD part.

Neither processor dominates comprehensively. The Pentium wins the majority of tests (5 of 7), but the Athlon wins the two largest-margin contests. The average scores are within 1.7% of each other, and the percentile ranks differ by only one point. For mixed workloads, the data does not clearly favor either part; the choice depends on which benchmark family matters more. The recorded data shows no price information, so no cost-based guidance is possible. The Pentium's 35W TDP versus the Athlon's 15W TDP may matter for thermal-constrained systems, but performance-per-watt calculations are not derivable from the available scores alone.

Architecture Differences

The two CPUs come from fundamentally different design lineages. The Intel Pentium G4560T uses the Kaby Lake architecture, built on a 14 nm process at Intel's foundry. The AMD Athlon PRO 3045B uses the Zen architecture with the Dali codename, also on a 14 nm process but fabricated by GlobalFoundries. Both use 14 nm, but the underlying microarchitectures diverge sharply.

The Pentium G4560T belongs to Intel's Pentium generation for Kaby Lake, while the Athlon is part of AMD's 3000 series, specifically the Athlon generation based on Zen (Dali). The Athlon's Zen design is a more modern microarchitecture in terms of IPC (instructions per clock), which likely explains its Geekbench single-core dominance despite a lower base clock. The Pentium's Kaby Lake design benefits from higher base clocks (2.90 GHz versus 2.30 GHz) and Intel's mature 14 nm process.

Cache hierarchies differ notably. The Pentium G4560T has 64 KB of L1 cache per core, 256 KB of L2 per core, and 3 MB of shared L3. The Athlon PRO 3045B has 96 KB of L1 per core, 512 KB of L2 per core, and 4 MB of shared L3. The AMD part has larger caches at every level, with 50% more L1, 100% more L2, and 33% more L3. This cache advantage may contribute to the Geekbench results, where memory latency and cache behavior often play a larger role.

The Athlon also carries more physical details in the database: 3,500 million transistors on a 148 mm² die. No transistor or die size figures are recorded for the Pentium. Both CPUs feature integrated graphics, but they differ: the Pentium has Intel HD 610, while the Athlon has Radeon Vega (2CU). The compute units of the Vega iGPU are not specified further, and no graphics benchmarks are recorded.

Specification Differences

The core and thread counts are identical: both parts have 2 cores and 4 threads. Both support DDR4 memory on a dual-channel bus with 38.4 GB/s bandwidth. Beyond these similarities, the specifications diverge in several key fields.

Clock speeds differ. The Pentium G4560T has a base clock of 2.90 GHz with no boost clock recorded. The Athlon PRO 3045B has a base clock of 2.30 GHz and a boost clock of 3.20 GHz. The Pentium's fixed 2.90 GHz is higher than the Athlon's base but lower than its boost, which explains the mixed benchmark outcomes.

Power consumption differs significantly. The Pentium G4560T has a TDP of 35W, while the Athlon PRO 3045B has a TDP of 15W. The Athlon draws less than half the thermal envelope of the Pentium, which is notable for compact or fanless designs. The Athlon's market segment is listed as Mobile, while the Pentium is Desktop, despite both being usable in similar form factors.

Sockets and platforms are incompatible. The Pentium uses Intel Socket 1151, while the Athlon uses AMD Socket FP5. The PCIe configurations also differ: the Pentium provides Gen 3 with 16 lanes (CPU only), while the Athlon provides Gen 3 with 12 lanes (CPU only). The Athlon supports ECC memory, while the Pentium does not. The Athlon's part number is YM3045C4T2OFG, and the Pentium's is SR35T. The Pentium has a recorded release date of 2017-01-02, while no release date is listed for the Athlon. Neither CPU has an unlocked multiplier, and neither has a recorded launch MSRP.
