Intel Xeon E5335

The Intel Xeon E5335 is a server/workstation processor from Intel, using the Core 2 architecture with the Clovertown codename. It has 4 cores and 4 threads, a base clock of 2000.00, and no boost clock. Built on a 65 nm process, it contains 582 million transistors on a 2x 143 mm² die arrangement. The database records an average benchmark score of 452 and a percentileVsAllCpus of 7.

Benchmark Performance

The E5335’s Cinebench results form a consistent picture. It scores 132 in Cinebench R15 multicore, 552 in R20 multicore, and 1316 in R23 multicore. The single-core results are 77 in R20 and 185 in R23. Those figures feed into an average benchmark score of 452. The percentileVsAllCpus value of 7 places the E5335 low in the database distribution, meaning most recorded CPUs sit above it in aggregate performance.

The nearest-rival table reinforces that position. The Intel Celeron G1610 has an average score of 452, which is identical to the E5335’s 452. The Intel Celeron J4005 also averages 452, with a deltaPct of 0. The AMD A4 PRO-7350B averages 451, a deltaPct of 0.1 from the E5335. The Intel Core i3-540 also averages 451, with a deltaPct of 0.2. The largest delta in the entire nearest-rival group is therefore 0.2 percent. In aggregate benchmark terms, the E5335 is effectively indistinguishable from these parts.

The cache hierarchy explains some of the E5335’s behavior. It has 64 KB of L1 cache per core and 4 MB of L2 cache per die, with no L3 cache listed. The die layout is 2x 143 mm², so the L2 cache is per die rather than shared across all 4 cores. The memory path is dual-channel, with DDR2/DDR3 support depending on the motherboard, and ECC memory support is enabled. A dual-channel bus with 4 MB of L2 per die gives the processor enough memory throughput for its server/workstation segment, but the low clock and 4-core/4-thread configuration cap its overall placement.

The R23 multicore score of 1316 is the highest Cinebench figure recorded for the E5335 in the FACT PACK. The R20 single-core score of 77 is the lowest. That gap shows a processor whose multi-threaded result benefits from having 4 physical cores, while its single-thread result is limited by the 2000.00 base clock and the 65 nm Core 2 design.

How It Compares

Against the Intel Celeron G1610, the E5335 shows an average score of 452 to 452. The deltaPct is 0, meaning there is no aggregate separation between the two. The Xeon branding does not produce a measurable benchmark advantage over this rival in the database.

Against the Intel Celeron J4005, the result is the same tie: 452 to 452, with a deltaPct of 0. The E5335 does not move above or below this rival in average score. The two CPUs sit on the same performance point despite their different market positioning.

Against the AMD A4 PRO-7350B, the E5335 leads by a deltaPct of 0.1. The average scores are 452 for the E5335 and 451 for the AMD part. This is a minimal lead, and it is the smallest nonzero gap in the nearest-rival list.

Against the Intel Core i3-540, the E5335 leads by a deltaPct of 0.2. The average scores are 452 versus 451. This is the largest delta among the listed nearest rivals, but it remains a narrow difference in aggregate performance.

Power and Thermals

The E5335 has a TDP of 80. For a quad-core processor built on a 65 nm process, this is a moderate thermal envelope. The die is arranged as 2x 143 mm², so the thermal load is spread across two dies under the processor package. The absence of a boost clock means sustained operation is defined by the 2000.00 base clock; the FACT PACK contains no higher operating state for this part.

Socket 771 and the Server/Workstation market segment point to cooling designed for continuous operation rather than enthusiast overclocking. The multiplier is locked, since multiplierUnlocked is false, so there is no user-controlled clock increase through an unlocked multiplier. The production status is end-of-life, so the 80 TDP class and its cooling implications apply to existing systems. An active socket cooler is implied by the TDP class; the E5335 is not positioned as a passive ultra-low-power part.

Single-Thread vs Multi-Thread Behavior

The benchmark data shows a clear split between single-thread and multi-thread performance. In Cinebench R20, the multi-core score is 552, while the single-core score is 77. In Cinebench R23, the multi-core score is 1316, while the single-core score is 185. In both cases, the multi-core result is far above the single-core result.

This pattern is consistent with a 4-core/4-thread processor. There are no extra logical threads per physical core, so the multi-threaded ceiling is set by the combined work of 4 physical cores. The base clock of 2000.00 and the absence of a boost clock place a hard limit on single-thread throughput. A single-thread-bound workload will run on a single core at that base clock, while a workload that uses all 4 physical cores can extract the full multi-threaded result.

The R20 pair, 77 single and 552 multi, indicates that the processor scales well when the workload can use all 4 cores. The R23 pair, 185 single and 1316 multi, shows the same behavior. For a Server/Workstation processor, this bias favors workloads that can occupy multiple cores. Workloads with a single dominant thread will be constrained by the E5335’s single-core capability, which is low relative to its multi-core result. The data therefore describes a processor built for parallel throughput, not for high single-thread responsiveness.
