CPU Comparison

Head-to-Head Benchmarks

The benchmark data presents a remarkably consistent picture: the Intel Xeon W3565 wins every single head-to-head comparison in the Cinebench suite. Across five tests, the Xeon's advantage hovers tightly between 18.1% and 18.4%. This uniformity suggests the performance gap is structural rather than workload-dependent, a function of core count, thread count, and clock behavior rather than any specific instruction path.

The largest delta appears in the Cinebench R20 multi-core test, where the Xeon W3565 scores 1212 against the Core i3-4130T's 1024, a difference of 18.4%. The same margin repeats in Cinebench R15 multi-core (290 vs 245) and Cinebench R23 multi-core (2888 vs 2440). These are not marginal victories; they represent a consistent, reproducible lead that holds across different rendering workloads and Cinebench versions.

Single-core results tell a similar story, though with slightly smaller margins. In Cinebench R20 single-core, the Xeon W3565 posts 170 versus the i3-4130T's 144, an 18.1% gap. Cinebench R23 single-core shows 407 versus 344, an 18.3% difference. The fact that the single-core lead is nearly as large as the multi-core lead is notable, it indicates the Xeon's advantage is not merely a matter of having more cores, but that each individual thread also executes faster.

The Core i3-4130T does have one benchmark category where it appears in the FACT PACK that the Xeon does not: Geekbench. The i3-4130T scores 1787 in Geekbench multi-core and 903 in single-core. However, since the Xeon W3565 has no Geekbench scores listed, no direct comparison is possible in that suite. The available head-to-head data is exclusively Cinebench, and it is unambiguous.

Looking at the aggregate benchmark scores, the Xeon W3565 averages 993 across its tested workloads, while the Core i3-4130T averages 984. That 9-point difference (approximately 0.9%) is far smaller than the Cinebench deltas would suggest. This discrepancy arises because the average includes different benchmark mixes, the Xeon's average covers five Cinebench tests, while the i3's average includes those same five plus two Geekbench results. The Geekbench scores pull the i3's average upward relative to its Cinebench performance.

Both processors land at the 27th percentile of all CPUs in the database. This means that despite the Xeon's clear wins in every direct comparison, both parts occupy the same performance tier when measured against the broader CPU landscape. The nearest rivals for each part reinforce this: the Xeon W3565 sits exactly level with the Core i7-965, Phenom II X6 1065T, and Core i7-960 (all at 993 average, 0% delta), while trailing the Core i3-8130U by just 0.1%. The Core i3-4130T matches the Core i7-875K exactly (984 average), leads the Xeon X3470 and Core i3-4370T by 0.1%, and trails the Xeon W5590 by 0.2%.

The Verdict

The data is decisive: the Intel Xeon W3565 is the faster processor in every direct benchmark comparison available. If raw Cinebench performance is the sole criterion, the Xeon W3565 is the clear choice. Its 18.4% multi-core advantage and 18.1-18.3% single-core advantage leave no ambiguity.

However, the verdict is not simply "pick the faster one." The two processors serve fundamentally different market segments. The Xeon W3565 is a Server/Workstation part on Socket 1366, while the Core i3-4130T is a Desktop part on Socket 1150. They are not drop-in alternatives for the same system. The socket difference alone means a platform decision must precede any CPU decision.

For a user building on an existing Socket 1366 workstation platform, the Xeon W3565 offers clearly superior performance in rendering workloads. For a user on Socket 1150, the Core i3-4130T is the only option between these two, and its 35W TDP versus the Xeon's 130W TDP makes it dramatically more energy-efficient, though the FACT PACK does not provide direct power consumption measurements.

The percentile data suggests both parts perform at the 27th percentile of all CPUs, meaning neither is a top-tier performer by modern standards. But within this head-to-head, the Xeon W3565 wins outright. The analysis must also note that the Xeon W3565 supports ECC memory while the Core i3-4130T does not, a meaningful differentiator for reliability-sensitive workloads.

Where Each One Wins

Intel Xeon W3565, Rendering and multi-threaded compute. Every Cinebench multi-core test favors the Xeon by 18.4%. With 4 cores and 8 threads versus the i3's 2 cores and 4 threads, the Xeon has twice the threading capacity. Its 8 MB shared L3 cache dwarfs the i3's 3 MB, and its 3.20 GHz base clock with 3.47 GHz boost exceeds the i3's 2.90 GHz base (the i3 has no boost clock listed). For CPU-bound rendering, video encoding, or scientific computing that scales across threads, the Xeon W3565 is the superior part.

Intel Core i3-4130T, Single-core efficiency and platform features. While the i3 loses every Cinebench test, it wins on architectural modernity. The Haswell architecture on a 22 nm process (versus Nehalem on 45 nm) is two generations newer. The i3 includes integrated graphics (Intel HD 4400) while the Xeon has none listed, meaning the i3 can power a display without a discrete GPU. The i3 also supports PCIe Gen 3 versus the Xeon's Gen 2. Its 35W TDP is 73% lower than the Xeon's 130W, making it suitable for compact, low-heat builds. The i3's 1,400 million transistors on a 177 mm² die also reflect a denser, more modern design than the Xeon's 731 million transistors on 263 mm².

The Geekbench edge. The Core i3-4130T has Geekbench scores (1787 multi-core, 903 single-core) that are not matched by any Xeon data in the FACT PACK. If a user's workload relies on Geekbench-specific metrics, the i3 at least provides measurable data while the Xeon has none.

Architecture Differences

The architectural gap between these two parts is substantial. The Xeon W3565 uses the Nehalem architecture (codename Bloomfield) built on Intel's 45 nm process. The Core i3-4130T uses the Haswell architecture (same codename) on a 22 nm process. This process shrink allowed Intel to pack 1,400 million transistors into a 177 mm² die for the i3, versus 731 million transistors on a 263 mm² die for the Xeon. The transistor density is dramatically higher on the newer part.

Cache hierarchies differ significantly. Both share the same L1 (64 KB per core) and L2 (256 KB per core) configurations, but the L3 cache diverges sharply: the Xeon W3565 has 8 MB shared L3, while the Core i3-4130T has only 3 MB shared. For workloads that repeatedly access a large working set, the Xeon's larger cache provides a structural advantage.

Memory architecture also differs. The Xeon supports triple-channel DDR3 memory, while the Core i3 uses dual-channel DDR3. Both support DDR3, but the Xeon's additional memory channel provides greater potential memory bandwidth (though the FACT PACK does not include bandwidth measurements). ECC memory support is exclusive to the Xeon.

PCIe generation differs: the Xeon offers PCIe Gen 2, while the Core i3 offers Gen 3. The newer PCIe standard doubles the per-lane bandwidth, which matters for GPU and NVMe connectivity. Integrated graphics are present only on the Core i3 (Intel HD 4400); the Xeon has no integrated graphics listed.

The release dates reflect the generational gap: the Xeon launched in 2009, the Core i3 in 2013. The Xeon is marked as End-of-life production status, while the i3's production status is not specified. The Xeon's part number is SLBEV; the i3's is SR1NN.

The specification table highlights that the Xeon W3565 is built for throughput, more cores, more threads, higher clocks, larger cache, triple-channel memory, and ECC support. The Core i3-4130T is built for efficiency, much lower TDP, newer process node, integrated graphics, and PCIe Gen 3. Neither part has an unlocked multiplier, so overclocking headroom is not a differentiator. The 45 nm versus 22 nm process gap explains the transistor and die size differences, while the TDP difference (130W versus 35W) reflects both the core count disparity and the efficiency gains of the newer manufacturing process.
