Intel Pentium G4600T vs Intel Xeon W3540 Comparison

Head-to-Head Benchmarks

The recorded data shows a consistent, though narrow, advantage for the Intel Xeon W3540 across every Cinebench workload in the comparison set. The Xeon W3540 wins all five head-to-head matchups, with a uniform delta of 1.9% in each test. This consistency is notable: the margin does not expand or contract based on workload type, whether single-core or multi-core.

In the Cinebench R15 multicore test, the Xeon W3540 scores 267 against the Pentium G4600T's 262. The 1.9% lead is small but real. Moving to Cinebench R20 multicore, the Xeon W3540 posts 1113 while the Pentium G4600T records 1092, again a 1.9% difference. The single-core results follow the same pattern: the Xeon W3540 reaches 157 in Cinebench R20 single-core, the Pentium G4600T trails at 154. In Cinebench R23, the Xeon W3540 delivers 374 single-core and 2652 multi-core, while the Pentium G4600T manages 367 and 2602, respectively. Every delta is exactly 1.9%.

The fact that the margin is identical across all five tests suggests the performance gap is not workload-dependent. It appears to be a fixed architectural or clock-related advantage rather than something that scales with thread count or cache pressure. The Xeon W3540's base clock is 2.93 GHz, while the Pentium G4600T runs at 3.00 GHz. Despite the Pentium's higher base clock, the Xeon W3540 still edges ahead, which points to other factors, such as the larger 8 MB shared L3 cache versus the Pentium's 3 MB, or the Xeon's eight threads versus the Pentium's four.

The average benchmark scores from the database's broader suite reinforce this picture. The Xeon W3540 has an average benchmark score of 913, while the Pentium G4600T sits at 895. That is a difference of 18 points, or roughly 2.0%, which aligns with the head-to-head deltas. Both processors land in the 24th percentile of all CPUs in the database, meaning they occupy the same performance tier overall, but the Xeon W3540 sits at the top of that tier.

Looking at nearest rivals for context, the Xeon W3540's average score of 913 places it within 0.5% of the AMD Ryzen 3 3250U (908, delta 0.5%) and 0.3% above the AMD PRO A12-9800E (910). It is 0.2% behind the Intel Pentium Gold G6405T (915) and 0.5% behind the AMD Athlon Silver 3050U (917). The Pentium G4600T's average score of 895 ties it exactly with the Intel Core i5-5300U and the AMD PRO A10-8770E, both at 895 with a 0% delta. It sits 0.2% above the AMD Ryzen 3 3200U (893) and 0.7% above the Intel Core i3-6100 (888).

These rival comparisons show that both CPUs are clustered in a very tight performance band. The difference between the best and worst scores in these rival groups is only about 1.2% for the Xeon W3540's group and 0.7% for the Pentium G4600T's group. The Xeon W3540's 1.9% head-to-head win over the Pentium G4600T is actually larger than the spread within either processor's nearest-rival set, which underscores that the gap, while small, is consistent and measurable.

The Verdict

The data is unambiguous: the Intel Xeon W3540 wins every benchmark in the comparison. It takes 5 wins out of 5 head-to-head tests. The Pentium G4600T records 0 wins. If the sole criterion is Cinebench performance, the Xeon W3540 is the superior processor, albeit by a modest 1.9% margin.

However, the broader system context matters. The Xeon W3540 is a server and workstation part from the Nehalem generation, built on a 45 nm process, with a 130 W TDP. It requires an Intel Socket 1366 platform and uses triple-channel DDR3 memory. The Pentium G4600T is a modern desktop chip on the Kaby Lake architecture, built on a 14 nm process, with a 35 W TDP. It uses Intel Socket 1151, dual-channel DDR4 memory, and includes integrated Intel HD 630 graphics.

The recorded data shows that in raw compute, the Xeon W3540 holds a slight edge in every tested workload. But the Pentium G4600T offers a dramatically lower power envelope, 35 W versus 130 W, and a much newer platform with DDR4 support and a PCIe Gen 3 interface. The Xeon W3540 supports ECC memory, which the Pentium does not. The Xeon W3540 also has twice the threads, 8 versus 4, and more than double the L3 cache, 8 MB versus 3 MB.

For a user who already owns a Socket 1366 motherboard and has DDR3 memory on hand, the Xeon W3540's 1.9% performance lead might be relevant. For anyone building a new system, the Pentium G4600T's lower power draw, integrated graphics, and modern platform features make it the more practical choice, even though it loses in every benchmark. The data shows a performance winner and a platform winner; they are not the same chip.

Where Each One Wins

The Xeon W3540 wins in all measured compute performance. Its multi-core advantage is driven by 8 threads versus 4, which matters in threaded workloads even if the 1.9% delta is modest. Its single-core advantage, despite a lower base clock, suggests the larger L3 cache or memory bandwidth configuration helps in latency-sensitive tasks. The triple-channel DDR3 memory bus, while older, provides more memory channels than the Pentium's dual-channel DDR4 setup. The Xeon W3540 also supports ECC memory, which is a functional win for reliability-sensitive workloads.

The Pentium G4600T wins in platform efficiency and integration. Its 35 W TDP is a fraction of the Xeon W3540's 130 W, which translates to lower cooling requirements and lower operating costs, even though the database does not record wattage figures for direct comparison. The Pentium includes integrated Intel HD 630 graphics, so it does not require a discrete GPU for basic display output. It supports DDR4 memory with a recorded bandwidth of 38.4 GB/s, and its PCIe Gen 3 interface with 16 lanes is newer than the Xeon's PCIe Gen 2. The Pentium's production status is Active, while the Xeon W3540 is End-of-life, which matters for availability and long-term support.

In terms of use cases, the Xeon W3540 is positioned for server or workstation duties where ECC memory and multi-threaded throughput are priorities. The Pentium G4600T is positioned for desktop use where low power, integrated graphics, and modern memory standards are more important than the last few percentage points of compute performance.
