AMD Athlon X4 950 vs Intel Pentium G4600 Comparison

The Intel Pentium G4600 and AMD Athlon X4 950 are two budget-oriented desktop processors from different architectural eras, and the benchmark data reveals a surprisingly consistent, though narrow, advantage for the Intel part. Across all five head-to-head Cinebench tests, the Pentium G4600 emerges as the winner, yet the margins are remarkably slim, often hovering around a single percentage point. This creates a fascinating dynamic where the Intel chip technically dominates the performance charts, but the practical difference for a user is negligible, making the choice between them a matter of architectural philosophy rather than raw speed.

Head-to-Head Benchmarks

The data from the head-to-head benchmarks paints a picture of near-parity with a consistent Intel edge. In the Cinebench R15 multi-core test, the Pentium G4600 scores 309 points against the Athlon’s 306, a victory of just 1%. This pattern repeats in the Cinebench R20 multi-core test, where the Intel chip scores 1289 versus 1277 for the AMD, giving it a 0.9% lead. The single-core results are even tighter. In Cinebench R20 single-core, the Pentium G4600 scores 181, while the Athlon X4 950 scores 180, a difference of only 0.6%. The Cinebench R23 suite follows the same trend, with the Intel part winning the multi-core test 3070 to 3041 (a 1% difference) and the single-core test 433 to 429 (a 0.9% difference).

The fact that the Intel Pentium G4600 secures all five wins is noteworthy given its fundamental hardware disadvantage in core count. The Athlon X4 950 is a true quad-core processor, while the Pentium is a dual-core part with Hyper-Threading, presenting itself as two physical and four logical cores. Despite having half the physical cores, the Pentium’s architectural efficiency from its 14 nm Kaby Lake design allows it to edge out the AMD chip, which relies on the older 28 nm Excavator architecture. The average benchmark score for the Pentium G4600 is 1056, slightly above the Athlon’s 1047, reinforcing the idea that the Intel part is the more consistent performer across the board. However, the margins are so small that they fall well within the bounds of run-to-run variance for most real-world applications.

When placed in the context of their respective peer groups, both CPUs occupy the same performance tier. The Pentium G4600 sits at the 29th percentile of all CPUs, with its nearest rival being the Intel Core i7-2760QM at an average score of 1057, a delta of -0.1%. The Athlon X4 950 also sits at the 29th percentile, and its closest competitor is the AMD PRO A10-8770 with an average score of 1046, a delta of 0.1%. This indicates that while the Intel chip is the winner in this direct comparison, neither processor is breaking new ground; they are both firmly planted in the entry-level segment, separated by a hair’s breadth in overall capability.

FAQ

Q: Do both processors support the same memory technology?

A: Yes. Both the Intel Pentium G4600 and the AMD Athlon X4 950 support DDR4 memory in a dual-channel configuration, and both have a memory bandwidth of 38.4 GB/s. Neither supports ECC memory.

The Verdict

Based strictly on the benchmark data, the Intel Pentium G4600 is the superior processor. It wins every single head-to-head test, which gives it a definitive 5-0 record. Its average benchmark score of 1056 is higher than the Athlon’s 1047, and it achieves this despite having fewer physical cores. The data suggests that for users who prioritize raw performance in Cinebench-style rendering workloads, the Pentium G4600 is the safer choice, even if the margin is statistically small.

However, the verdict is not a clean sweep in terms of practical value. The performance delta is so narrow—never exceeding 1%—that the Athlon X4 950 is effectively a peer of the Pentium in execution. The Athlon’s 4 physical cores may offer a different kind of robustness in multi-threaded scenarios that are not captured by these specific benchmarks, but the data provided does not support such a claim. For a user deciding between the two, the Pentium G4600 is the pick if the goal is to extract the maximum benchmark score, while the Athlon X4 950 is a reasonable alternative that trades a marginal amount of performance for a different core configuration. The 29th percentile ranking for both CPUs indicates that neither is a high-performance part, and the choice between them will have minimal impact on overall system feel for general use.

Specification Differences

The most significant difference lies in the core and thread counts. The Intel Pentium G4600 is a dual-core processor with 4 threads, while the AMD Athlon X4 950 is a quad-core processor with 4 threads. This means the AMD chip has double the physical cores, but the Intel chip uses simultaneous multithreading to achieve the same thread count. The base clocks are similar, with the Pentium at 3.60 GHz and the Athlon at 3.50 GHz, but the Athlon also has a boost clock of 3.80 GHz, which the Pentium lacks. The power envelopes differ notably, with the Intel chip rated at a 51 W TDP and the AMD chip at 65 W.

The socket and platform requirements are entirely different. The Pentium G4600 uses the Intel Socket 1151, while the Athlon X4 950 uses the AMD Socket AM4. The integrated graphics situation is also a major differentiator: the Intel part includes Intel HD 630 graphics, whereas the Athlon X4 950 has no integrated graphics, requiring a discrete GPU for display output. PCIe lane support varies, with the Intel CPU offering 16 lanes and the AMD CPU offering 8 lanes, both Gen 3. The Intel part has a smaller cache allocation in terms of L2 (256 KB per core) but adds a 3 MB shared L3 cache, which the AMD part lacks entirely, relying instead on 2 MB of L2 cache and 320 KB of L1 cache.

Architecture Differences

The architectural divide between these two CPUs is stark and explains their performance characteristics. The Intel Pentium G4600 is built on the Kaby Lake architecture using a 14 nm process node fabricated by Intel. In contrast, the AMD Athlon X4 950 is based on the Excavator architecture, using the older 28 nm process node fabricated by GlobalFoundries. This process difference is a key factor in the Intel chip’s ability to match the AMD part’s multi-core performance despite having fewer physical cores. The AMD chip’s larger physical footprint is evident in its die size of 250 mm² and transistor count of 3,100 million, while the Intel chip’s die size and transistor count are not provided.

The cache hierarchies are fundamentally different. The Intel processor uses a per-core L1 cache of 64 KB and a per-core L2 cache of 256 KB, supplemented by a shared 3 MB L3 cache. The AMD processor uses a unified L1 cache of 320 KB and a 2 MB L2 cache, with no L3 cache present. This means the Intel chip has a more complex memory hierarchy that can potentially speed up access to frequently used data. The manufacturing dates also separate them, with the Intel part releasing on 2017-01-02 and the AMD part releasing later on 2017-07-26. Both are listed as active in production, and neither has an unlocked multiplier, indicating they are not designed for overclocking.

Where Each One Wins

Given the data, the Intel Pentium G4600 is the winner in every benchmark category recorded, including both multi-core and single-core tests in Cinebench R15, R20, and R23. This makes it the default choice for users who rely on these specific rendering workloads. Its integrated Intel HD 630 graphics also give it a distinct advantage in systems where a discrete GPU is not present, allowing for basic display output and multimedia tasks without additional hardware. The lower 51 W TDP also makes it a more power-efficient option for compact or low-power builds.

The AMD Athlon X4 950, despite losing all head-to-head tests, has its own set of strengths based on its specifications. Its 4 physical cores could be beneficial in scenarios that are heavily multi-threaded but do not scale perfectly with logical cores, though the benchmark data does not show this advantage. The presence of a boost clock up to 3.80 GHz offers a slight dynamic performance headroom that the Intel part cannot match. For a user building on the AM4 platform, the Athlon X4 950 serves as a functional entry point, but the data suggests it will trail the Pentium G4600 in the tested workloads. The lack of integrated graphics is a clear disadvantage for basic system functionality, but for a user who already owns a discrete GPU, this is a non-issue. Ultimately, the Intel chip wins on pure benchmark performance, while the AMD chip offers a different core topology and platform choice, albeit with a measurable performance deficit.
