AMD PRO A10-8750B vs Intel Xeon X3440 Comparison

The AMD PRO A10-8750B and Intel Xeon X3440 are both end-of-life desktop and server processors respectively, yet they land remarkably close in aggregate performance. The AMD part edges ahead in every benchmark recorded, but the Intel chip counters with a significant thread advantage and ECC memory support. Benchmark data shows the AMD PRO A10-8750B holds a slim but consistent lead across all Cinebench tests, while both CPUs sit at the 22nd percentile of all processors, making this a contest decided by small margins and feature sets rather than outright dominance.

Head-to-Head Benchmarks

The AMD PRO A10-8750B wins all five head-to-head comparisons, though the margins are modest. In Cinebench R15 multi-core, the AMD scores 254 against the Intel’s 238, a 6.7% advantage. That pattern repeats in Cinebench R20 multi-core, where AMD posts 1060 versus 994, a 6.6% lead. The single-core results tell the same story: AMD’s 149 in R20 single-core beats Intel’s 140 by 6.4%, and in R23 single-core, the AMD’s 356 tops the Intel’s 334 by 6.6%.

The largest absolute gap appears in Cinebench R23 multi-core, where the AMD scores 2525 and the Intel scores 2368 — a 157-point difference, again 6.6%. Interestingly, the AMD’s advantage is remarkably consistent, hovering near 6.6% across every test. This suggests a fundamental clock-speed or IPC advantage rather than a workload-specific quirk.

However, the Intel Xeon X3440 has a structural advantage that the benchmarks do not fully capture: it offers 8 threads versus the AMD’s 4 threads. Despite having half the thread count, the AMD still wins multi-threaded tests, indicating that its 3.60 GHz base and 4.00 GHz boost clocks (versus Intel’s 2.53 GHz base and 2.93 GHz boost) more than compensate. The data shows that in fully threaded workloads, the AMD’s higher frequency per core outweighs the Intel’s hyper-threading benefit.

The average benchmark scores reflect this near-parity: the AMD averages 821 points, while the Intel averages 815 points. The nearest-rival data places the Intel Xeon E5540 at 820 (0.1% from AMD) and the Intel Core i5-L16G7 at 816 (0.6% from AMD), confirming that both chips occupy the same performance tier. The AMD’s closest rival is actually its own sibling, the AMD A10 PRO-7850B, which scores 828 and beats it by 0.8%.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD PRO A10-8750B uses the Steamroller architecture on a 28 nm process from GlobalFoundries, packing 2,411 million transistors into a 245 mm² die. The Intel Xeon X3440 uses the older Nehalem architecture on Intel’s 45 nm process, with just 774 million transistors spread across a larger 296 mm² die. This generational gap explains why the AMD achieves higher clocks despite similar power envelopes.

Cache configurations differ sharply. The AMD provides 256 KB of L1 and 4 MB of L2 cache, with no L3 cache at all. The Intel counters with 64 KB of L1 per core and 256 KB of L2 per core, but crucially adds 8 MB of shared L3 cache. This L3 presence helps the Intel in cache-sensitive workloads, yet benchmark results suggest it is insufficient to overcome the AMD’s raw frequency advantage.

The integrated graphics situation is one-sided. The AMD integrates a Radeon R7 GPU, making it a complete APU solution, while the Intel Xeon has no integrated graphics whatsoever. This means the AMD can drive a display without a discrete card, whereas the Intel requires a separate GPU. The AMD also supports PCIe Gen 3 with 16 lanes, while the Intel is limited to PCIe Gen 2 with 16 lanes.

Memory support reveals another divergence. Both support dual-channel DDR3, but the AMD’s memory bandwidth is rated at 34.1 GB/s versus the Intel’s 21.3 GB/s — a 60% advantage for the AMD. However, the Intel supports ECC memory while the AMD does not, making the Xeon more suitable for error-sensitive workloads. The AMD’s release date of September 2015 comes six years after the Intel’s September 2009 launch, explaining the process and architectural improvements.

The Verdict

The benchmark data is unambiguous: the AMD PRO A10-8750B outperforms the Intel Xeon X3440 in every recorded test, with a consistent 6.6% lead across Cinebench workloads. The AMD’s higher clock speeds and newer 28 nm process overcome the Intel’s thread advantage and generous L3 cache. For users prioritizing raw benchmark scores, the AMD is the clear choice.

However, the Intel Xeon X3440 serves a different purpose. Its 8 threads and ECC memory support target server and workstation environments where data integrity matters more than peak throughput. The AMD’s lack of ECC support disqualifies it from many reliability-critical applications. The Intel also holds a launch MSRP of $215, providing a historical price reference absent for the AMD.

The AMD wins on integrated graphics, memory bandwidth, and every benchmark. The AMD’s Radeon R7 GPU makes it a self-contained solution for basic display output, while the Intel requires a discrete graphics card. The AMD’s 34.1 GB/s memory bandwidth is 60% higher than the Intel’s 21.3 GB/s, further cementing its performance edge.

For desktop users seeking the faster processor, the AMD PRO A10-8750B is the data-backed pick. It wins all five head-to-head comparisons and holds a 0.8% higher average benchmark score. For server or workstation builders requiring ECC memory and multi-threaded reliability, the Intel Xeon X3440 remains relevant despite its age. The choice reduces to workload requirements: the AMD for speed and integration, the Intel for memory error correction and thread count. Both processors sit at the 22nd percentile of all CPUs, so neither offers advanced performance today. But within this specific matchup, the AMD PRO A10-8750B is the benchmark champion.
