Intel Core i3-4330T vs Intel Xeon X5550 Comparison

Head-to-Head Benchmarks

The recorded data shows a consistent, though narrow, victory for the Intel Core i3-4330T across every Cinebench iteration in the comparison. The Xeon X5550 does not secure a single win in the head-to-head tests, with all five benchmarks favoring the newer desktop chip.

In Cinebench R15 multi-core, the i3-4330T scores 265 against the Xeon's 259, a 2.3% advantage. That pattern repeats in Cinebench R20 multi-core, where the i3 posts 1108 versus 1083, again a 2.3% delta. The single-core results are similarly tight but favor the i3: a 156 to 152 result in R20 single-core (2.6% ahead) and a 372 to 364 result in R23 single-core (2.2% ahead). The R23 multi-core test shows the i3 at 2639 against 2580, a 2.2% margin.

These are not dramatic differences; the largest gap is just 2.6%. What matters is that the i3-4330T, despite having only two physical cores and four threads, consistently outperforms the four-core, eight-thread Xeon X5550. This illustrates how architectural generation can outweigh raw core counts. The Xeon's average benchmark score sits at 888, while the i3 averages 908, a 20-point difference that places them in the same performance tier overall.

The Xeon's nearest rivals in the database include the Intel Core i3-6100 at an identical 888 average score (0% delta), the Pentium G4560T at 887 (0.1% delta), and the AMD PRO A8-8650B also at 887. The i3-4330T's neighbors include the Core i3-10110Y and Ryzen 3 3250U, both at 908 (0% delta), with the AMD PRO A12-9800E slightly ahead at 910 (-0.3% delta from the i3). Both CPUs sit at the 24th percentile among all processors tracked in the database, confirming they occupy similar mid-low positions in the overall performance distribution.

FAQ

Architecture Differences

The Xeon X5550 is built on the Nehalem architecture with the Gainestown codename, fabricated on a 45 nm process node. It contains 731 million transistors on a 263 mm² die. The Core i3-4330T uses the Haswell architecture (same codename), fabricated on a 22 nm process node. Despite the smaller die size of 177 mm², the Haswell chip packs 1,400 million transistors, reflecting a significantly denser manufacturing process.

Cache configurations differ notably. Both allocate 64 KB of L1 cache per core and 256 KB of L2 cache per core. The shared L3 cache, however, is double on the Xeon: 8 MB shared versus 4 MB shared on the i3. This larger pool of last-level cache is typical for a server-oriented part, but the benchmark data shows it does not overcome the architectural efficiency of Haswell.

Memory support also diverges. The Xeon uses a triple-channel DDR3 memory bus, while the i3 uses a dual-channel DDR3 bus. The Xeon carries PCIe Gen 2 support, while the i3 supports PCIe Gen 3, which doubles the available bandwidth per lane for compatible devices. The i3 also integrates Intel HD 4600 graphics, a feature entirely absent from the Xeon.

The process node shrink from 45 nm to 22 nm, combined with the architectural improvements from Nehalem to Haswell, explains the performance parity despite the Xeon's core and thread advantage. The i3 achieves higher or equal scores with half the cores, half the threads, and half the L3 cache.

Where Each One Wins

The benchmark results are unambiguous: the Core i3-4330T wins every performance test in the head-to-head comparison. There is no workload category in the recorded data where the Xeon X5550 comes out ahead. The i3's wins span both single-core and multi-core workloads, covering Cinebench R15, R20, and R23.

That said, the use-case split goes beyond the raw Cinebench scores. The Xeon X5550 offers features that matter in server and workstation environments. It supports ECC memory, which is critical for error correction in long-running compute tasks. It also uses a triple-channel memory bus, which can provide higher aggregate memory bandwidth for memory-intensive workloads, even if the database does not list a specific bandwidth figure. The larger 8 MB L3 cache may also benefit workloads with large working sets that fit within that cache.

The Core i3-4330T, by contrast, brings integrated graphics, a much lower 35-watt TDP, and PCIe Gen 3 support. The i3 is better suited for compact desktop builds where a discrete GPU is not required and power efficiency is a priority. Its 3.00 GHz base clock is higher than the Xeon's 2.67 GHz base, and it does not need a boost clock to maintain a lead in single-threaded performance.

For multi-threaded server-style workloads that rely on more physical cores and ECC memory, the Xeon remains a functional choice, but its performance ceiling in these specific Cinebench tests is lower than the i3's. The data does not show any scenario where the Xeon's extra cores translate into a win.

The Verdict

The database is clear: the Intel Core i3-4330T is the faster processor in every measured benchmark. It wins all five head-to-head tests, holds a higher average benchmark score (908 versus 888), and does so while consuming less than half the power (35 watts versus 95 watts). For anyone building a system where Cinebench-style performance matters, the i3 is the better pick.

The Xeon X5550 should be chosen only when its specific platform features are required. ECC memory support and the triple-channel memory bus are not available on the i3. If the application demands error-correcting memory or a Socket 1366 server board, the Xeon has a purpose. Its 8 MB L3 cache and 8 threads also make it a more traditional multi-core server part, even if the benchmarks show it lagging.

The i3-4330T, on the other hand, offers a superior combination of performance, efficiency, and integrated graphics. Its 24th percentile ranking matches the Xeon's, but it achieves that rank with fewer cores and a lower TDP. The 2.2% to 2.6% margins are small, but they are consistent across every test.

In practical terms, the Xeon is an end-of-life server component that has been surpassed by a low-power desktop chip from a later generation. The i3 is the rational choice for almost all workloads represented in this data. The only reason to select the Xeon is platform compatibility or the need for ECC memory, both of which fall outside the Cinebench performance metrics. For raw compute performance as measured here, the Core i3-4330T wins outright.
