AMD Athlon PRO 3045B vs Intel Core i3-1000NG4 Comparison

Head-to-Head Benchmarks

The recorded data shows a consistent and decisive advantage for the Intel Core i3-1000NG4 across every shared benchmark test. Out of five head-to-head comparisons, the Intel part wins all five, with the AMD Athlon PRO 3045B failing to secure a single victory. The margins are remarkably uniform, hovering around 27% in every workload category.

Starting with multi-core performance, the Intel Core i3-1000NG4 scores 301 points in Cinebench R15 multi-core, while the AMD Athlon PRO 3045B manages 237 points. That is a 27% advantage for Intel. The pattern repeats in Cinebench R20 multi-core, where Intel posts 1255 points against AMD's 988, again a 27% delta. In Cinebench R23 multi-core, the Intel part reaches 2989 points, while the AMD chip settles at 2354, maintaining the same 27% gap. The consistency of these multi-core deltas across three different Cinebench versions suggests a stable architectural advantage rather than a workload-specific quirk.

Single-core results tell a similar story. In Cinebench R20 single-core, the Intel Core i3-1000NG4 scores 177 points versus 139 for the AMD Athlon PRO 3045B, a 27.3% lead. Cinebench R23 single-core shows Intel at 422 points and AMD at 332, a 27.1% delta. The Intel chip also has a Cinebench R15 single-core result of 141 points, though the AMD part has no corresponding score in that specific test within the database, so no direct comparison is possible for that particular metric.

These rival clusters show that both chips compete in a similar performance neighborhood, even though the direct comparison favors Intel substantially.

The Verdict

The data points to a clear winner for anyone choosing between these two processors on raw performance. The Intel Core i3-1000NG4 beats the AMD Athlon PRO 3045B by roughly 27% in every Cinebench test where both have recorded scores, covering both single-core and multi-core workloads across R15, R20, and R23 versions. The Intel part also holds a higher average benchmark score overall: 881 versus 872.

However, the AMD Athlon PRO 3045B is not without its own considerations. It remains an active production part, while the Intel Core i3-1000NG4 is end-of-life. The AMD chip also supports ECC memory, a feature the Intel part lacks entirely. For environments where error-correcting memory is a requirement, the AMD Athlon PRO 3045B becomes the only viable choice between these two, regardless of its lower benchmark scores.

For general-purpose computing where benchmark performance is the primary criterion, the Intel Core i3-1000NG4 is the stronger pick. The 27% margins are substantial and consistent, and the Intel part achieves them while drawing less power on paper. For specialized use cases that demand ECC memory support or require an actively produced processor, the AMD Athlon PRO 3045B is the appropriate selection despite its performance deficit.

Both processors are locked multipliers, so neither offers overclocking headroom. Both sit at the 23rd percentile among all CPUs, indicating that neither is a high-performance part by modern standards. The choice ultimately comes down to whether raw Cinebench performance or feature support matters more for the intended application.

Specification Differences

The two processors share several key specifications but differ in many others. Both are 2-core, 4-thread parts with a boost clock of 3.20 GHz, and both use DDR4 memory with dual-channel memory support. Beyond those basics, the specifications diverge significantly.

The Intel Core i3-1000NG4 has a base clock of 1.10 GHz, 80 KB L1 cache per core, 256 KB L2 cache per core, and 4 MB of shared L3 cache. The AMD Athlon PRO 3045B has a base clock of 2.30 GHz, 96 KB L1 cache per core, 512 KB L2 cache per core, and 4 MB of shared L3 cache. The AMD part also lists 3,500 million transistors and a die size of 148 mm², while the Intel chip has a die size of 1.10 mm² listed in its base clock field, though this appears to be a data entry quirk in the source material.

The Intel Core i3-1000NG4 is built on a 10 nm process by Intel and uses the Intel BGA 1044 socket with a TDP of 9. The AMD Athlon PRO 3045B uses a 14 nm process by GlobalFoundries, fits the AMD Socket FP5, and has a TDP of 15. The AMD part supports ECC memory and has a memory bandwidth of 38.4 GB/s, while the Intel part has no recorded memory bandwidth figure and does not support ECC. Both support PCIe Gen 3, though the AMD part specifies 12 lanes (CPU only) while the Intel part does not give a lane count.

The integrated graphics differ as well. The Intel Core i3-1000NG4 uses Iris Plus (48EU), while the AMD Athlon PRO 3045B uses Radeon Vega (2CU). The Intel part is a mobile segment processor that is end-of-life, released on 2020-03-17, with the part number SRGM9. The AMD part is also a mobile segment processor but is active, has no recorded release date, and uses the part number YM3045C4T2OFG.

Architecture Differences

The architectural divide between these two processors is substantial. The Intel Core i3-1000NG4 uses the Ice Lake architecture, specifically the Ice Lake-Y codename, and belongs to the Core i3 generation built on Sunny Cove-Y cores. It is fabricated at 10 nm by Intel. The AMD Athlon PRO 3045B uses the Zen architecture with the Dali codename, belongs to the Athlon generation built on Zen (Dali) cores, and is fabricated at 14 nm by GlobalFoundries.

The cache hierarchies differ in capacity per core. The Intel part allocates 80 KB of L1 and 256 KB of L2 per core, while the AMD part allocates 96 KB of L1 and 512 KB of L2 per core. Both share 4 MB of L3 cache. The AMD part's larger per-core caches and higher base clock of 2.30 GHz do not translate into a performance advantage in the recorded benchmarks, which suggests the Intel part's 10 nm process and newer core design compensate for its lower 1.10 GHz base clock.

The Intel Core i3-1000NG4 features Iris Plus integrated graphics with 48 execution units, while the AMD Athlon PRO 3045B features Radeon Vega with 2 compute units. The Intel part has a die size of 123 mm², while the AMD part has a die size of 148 mm² and lists 3,500 million transistors. The AMD part supports ECC memory and specifies a memory bandwidth of 38.4 GB/s, neither of which is present for the Intel part. Both use PCIe Gen 3, but the AMD part explicitly lists 12 lanes (CPU only).

Where Each One Wins

The benchmark data gives the Intel Core i3-1000NG4 a clean sweep in compute performance. It wins all five recorded head-to-head tests, covering Cinebench R15 multi-core, R20 multi-core, R20 single-core, R23 multi-core, and R23 single-core. The margins are consistently around 27%, which indicates a broad and uniform strength across both single-threaded and multi-threaded workloads. The Intel part also edges out the AMD part in average benchmark score, 881 to 872.

The AMD Athlon PRO 3045B wins in areas that are not captured by Cinebench scores. It is an active production part, whereas the Intel Core i3-1000NG4 is end-of-life. It supports ECC memory, which the Intel part does not. It has a higher base clock of 2.30 GHz and larger per-core L1 and L2 caches, and it lists a memory bandwidth figure of 38.4 GB/s. For applications that require ECC memory, the AMD part is the only option between the two. For anyone who needs an actively produced processor with ongoing availability, the AMD part also holds the advantage.

For raw compute throughput in Cinebench-style workloads, the Intel Core i3-1000NG4 is the clear winner. For feature-driven requirements such as ECC support and production status, the AMD Athlon PRO 3045B is the better fit. The use case determines the appropriate choice: benchmark-focused buyers should select Intel, while buyers with specific platform requirements should select AMD.
