Intel Core i5-4330M vs Intel Xeon W3570 Comparison

Head-to-Head Benchmarks

The recorded data shows the Intel Xeon W3570 winning every single benchmark in this head-to-head comparison. The margin is consistent, with the Xeon holding a 1.7% to 1.8% advantage across all five Cinebench tests. In single-core workloads, the Xeon W3570 scores 164 versus 161 in Cinebench R20, and 392 versus 385 in Cinebench R23. The delta of 1.8% in both cases reflects the Xeon's modest base clock advantage of 3.20 GHz versus 2.80 GHz, though the Core i5-4330M has a higher boost clock at 3.80 GHz versus the Xeon's 3.47 GHz.

Multi-core results tell a similar story. The Xeon W3570 leads by 1.8% in Cinebench R15 (279 versus 274) and by 1.7% in Cinebench R20 (1165 versus 1145). The largest absolute gap comes in Cinebench R23 multi-core, where the Xeon scores 2776 against the Core i5's 2727, a 1.8% difference. This consistency across test generations is striking: regardless of workload intensity or rendering duration, the Xeon W3570 maintains roughly the same proportional advantage.

What makes these margins notable is the underlying hardware disparity. The Xeon W3570 packs 4 cores and 8 threads against the Core i5-4330M's 2 cores and 4 threads, yet the performance gap remains under 2% in every test. The Core i5's newer Haswell architecture and 22 nm process node clearly compensate for its core-count deficit. Had the Core i5 been a desktop part rather than a 37 W mobile chip, the results might have looked very different. As recorded, the Xeon W3570's extra cores do not translate into the kind of multi-core dominance its specifications might suggest.

Comparing these CPUs to their broader peer groups reinforces the picture. The Core i5-4330M sits at the 25th percentile of all CPUs with an average benchmark score of 938, while the Xeon W3570 also sits at the 25th percentile with an average score of 955. The Xeon's nearest rival is the Intel Celeron N5105, matching its score exactly at 955 with a 0% delta, followed by the Intel Xeon W3550 and AMD Athlon X4 870K, both at 956 with a 0.1% delta in their favor. The Core i5's closest competition includes the Intel Core i3-8145U at 941 (0.4% ahead of the i5) and the Intel Core i7-2715QE at 942 (0.4% ahead).

Where Each One Wins

The Intel Xeon W3570 wins every recorded benchmark, making it the straightforward choice for pure performance. Its advantages are most apparent in multi-threaded rendering workloads, where the combination of 4 cores, 8 threads, and an 8 MB shared L3 cache provides a stable edge. The Xeon also wins single-core tests, though by a narrower margin. Users running Cinebench-style workloads or any multi-threaded rendering application would see consistently higher scores, roughly 1.7% to 1.8% better than the Core i5-4330M.

The Core i5-4330M wins in every category that does not involve raw benchmark scores. It draws far less power, with a 37 W TDP against the Xeon's 130 W, making it suitable for mobile systems. It integrates Intel HD 5000 graphics, eliminating the need for a separate GPU in basic display tasks. Its Haswell architecture on a 22 nm process node represents a much newer design generation than the Xeon's 45 nm Nehalem silicon. The Core i5 also fits the Intel Socket G3, a mobile platform, whereas the Xeon W3570 requires the desktop-class Intel Socket 1366.

For users building a workstation with an existing LGA1366 motherboard, the Xeon W3570 offers slightly better performance and ECC memory support. For users prioritizing portability, power efficiency, or integrated graphics, the Core i5-4330M is the only viable option. The data shows a performance gap of under 2%, which is unlikely to be perceptible in real-world use, so other factors like power draw, platform compatibility, and ECC support will likely determine the better choice.

Specification Differences

The two processors differ in nearly every fundamental specification. The Core i5-4330M has 2 cores and 4 threads, while the Xeon W3570 has 4 cores and 8 threads. Base clocks differ by 0.40 GHz, with the Xeon at 3.20 GHz and the Core i5 at 2.80 GHz. The boost clock reverses this relationship: the Core i5 boosts to 3.80 GHz, while the Xeon tops out at 3.47 GHz. TDP is dramatically different, with the Core i5 drawing 37 W against the Xeon's 130 W.

The Core i5-4330M uses the Intel Socket G3, while the Xeon W3570 uses the Intel Socket 1366. Process nodes differ by two generations: 22 nm for the Core i5 versus 45 nm for the Xeon. The transistor counts reflect this: the Core i5 packs 1,400 million transistors on a 118 mm² die, while the Xeon has 731 million transistors on a 263 mm² die. L3 cache favors the Xeon at 8 MB shared, compared to 3 MB shared for the Core i5. L1 and L2 caches are identical at 64 KB per core and 256 KB per core respectively.

The Xeon W3570 supports ECC memory and triple-channel memory, features not recorded for the Core i5. The Xeon also lists PCIe Gen 2 support, while no PCIe generation is recorded for the Core i5. The Core i5 includes integrated Intel HD 5000 graphics; the Xeon has no integrated graphics. The Core i5 targets the mobile market segment, while the Xeon targets servers and workstations. The Xeon is marked as end-of-life production status, while no production status is recorded for the Core i5. The Xeon has a part number of SLBES, while the Core i5 has none recorded. Release dates differ by over four years, with the Core i5 arriving in August 2013 and the Xeon in March 2009.

Architecture Differences

The Core i5-4330M belongs to the Haswell architecture, codenamed Haswell, built on Intel's 22 nm process. The Xeon W3570 belongs to the Nehalem architecture, codenamed Bloomfield, built on the older 45 nm process. This architectural gap explains several observed differences. The Haswell design achieves higher clock speeds at much lower power, evidenced by the Core i5's 3.80 GHz boost clock within a 37 W TDP envelope. The Nehalem design, despite its larger 263 mm² die and 130 W TDP, can only reach 3.47 GHz.

Cache hierarchies differ in total capacity but not in per-core organization. Both use 64 KB L1 and 256 KB L2 per core. The Xeon's 8 MB shared L3 cache doubles the Core i5's 3 MB, a meaningful advantage in multi-threaded workloads where shared data accesses are common. The Core i5 compensates with a much denser transistor layout: 1,400 million transistors on a 118 mm² die, versus 731 million on the larger 263 mm² Xeon die.

Memory architecture differs as well. The Xeon W3570 supports triple-channel DDR3 memory and ECC, making it suitable for error-sensitive workstation tasks. The Core i5-4330M supports DDR3 without recorded ECC capability or memory bus width. The Xeon's integrated memory controller, part of the Nehalem design, was a significant architectural shift for Intel, though the database does not record specific bandwidth figures. The Core i5's Haswell architecture is several generations newer, incorporating improvements in instruction efficiency and power management that help explain its competitive performance despite lower core counts and cache capacity.

The Verdict

The data points to a clear, if narrow, performance winner: the Intel Xeon W3570. It beats the Core i5-4330M in all five recorded benchmarks, with margins between 1.7% and 1.8%. Its 4 cores, 8 threads, and 8 MB L3 cache give it a structural advantage in any workload that scales with parallelism. The ECC memory support and triple-channel memory interface further cement its position for workstation and server use cases. Anyone running rendering workloads on a platform that supports Socket 1366 should pick the Xeon W3570 without hesitation.

The Core i5-4330M is not without merit. Its 37 W TDP makes it dramatically more power-efficient than the Xeon's 130 W. Its integrated Intel HD 5000 graphics remove the need for a discrete GPU in basic systems. Its 22 nm Haswell architecture represents a much newer design, and its 3.80 GHz boost clock shows that newer nodes can achieve higher frequencies at a fraction of the power. For mobile systems on Intel Socket G3, the Core i5-4330M is the only choice between these two. The performance gap of under 2% is minor enough that users should base their decision on platform compatibility, power constraints, and feature requirements rather than benchmark scores.

Neither processor stands out within the broader CPU landscape. Both sit at the 25th percentile of all CPUs, and both are closely matched with their nearest rivals. The Xeon W3570's average score of 955 places it alongside the Intel Celeron N5105, Intel Xeon W3550, and AMD Athlon X4 870K. The Core i5-4330M's average of 938 places it near the Intel Core i3-8145U and Intel Core i7-2715QE. In the end, the Xeon W3570 wins on performance and workstation features, while the Core i5-4330M wins on efficiency, mobility, and integrated graphics. The right pick depends entirely on the target platform and workload priorities.
