Intel Core i7-4910MQ vs Intel Xeon E3-1265L v4 Comparison

The Intel Core i7-4910MQ and Intel Xeon E3-1265L v4 are both end-of-life Intel processors with four cores and eight threads, yet they target very different market segments—one is a mobile chip, the other a server/workstation part. Despite the Xeon’s lower clock speeds and lower thermal design power, the benchmark data consistently shows the Xeon E3-1265L v4 winning every single head-to-head test, often by a margin of roughly 10 percent. This creates an interesting dynamic: the mobile i7, which was launched with a higher MSRP and higher clocks, is consistently outperformed by a lower-power server chip. The data suggests that architectural generation and integrated graphics play a larger role than raw clock speed in these specific workloads.

Head-to-Head Benchmarks

The head-to-head results are remarkably one-sided. The Intel Xeon E3-1265L v4 wins all six benchmark comparisons, with the Core i7-4910MQ trailing by nearly identical margins across the board. In Cinebench R15 multi-core, the Xeon scores 595 against the i7’s 536, a delta of -9.9 percent for the i7. Single-core R15 shows a similar story: 84 versus 75, a -10.7 percent gap. This pattern repeats in Cinebench R20, where the Xeon posts 2482 multi-core and 350 single-core, while the i7 manages 2236 and 315, respectively—both roughly 10 percent behind. The newest Cinebench R23 results follow the same trend: the Xeon leads with 5910 multi-core and 834 single-core, compared to the i7’s 5326 and 752, showing deltas of -9.9 percent and -9.8 percent.

What is striking is the consistency of the gap. Whether the workload is multi-threaded or single-threaded, the Xeon’s advantage hovers around 10 percent. This is not a case where one chip excels in a specific type of test; the Xeon simply dominates every metric. The i7-4910MQ’s higher base clock of 2.90 GHz and boost clock of 3.90 GHz are not enough to overcome the Xeon’s architectural advantages. The Xeon, despite running at 2.30 GHz base and 3.30 GHz boost, delivers more performance per clock in these Cinebench workloads, likely due to its newer Broadwell architecture and faster memory bandwidth. Interestingly, the i7’s average benchmark score of 1716 is only 0.4 percent higher than the Xeon’s 1709, but that average includes Geekbench results—which the Xeon lacks in the data—so the head-to-head Cinebench results are the more reliable direct comparison.

FAQ

Q: Why does the Xeon E3-1265L v4 win every benchmark despite having lower clock speeds?

A: The Xeon is built on a newer 14 nm process node (Broadwell) compared to the i7-4910MQ’s 22 nm Haswell node. The data shows the Xeon wins all six head-to-head Cinebench tests by roughly 10 percent, despite lower base and boost clocks. This suggests architectural efficiency and memory bandwidth (29.9 GB/s vs. 25.6 GB/s) contribute more to these scores than raw clock speed.

Q: How significant is the performance gap between these two processors?

Both chips are within 0.4 percent of each other, indicating they occupy a similar performance tier despite their different designs.

Q: Does the Xeon support ECC memory?

A: Yes, the Xeon E3-1265L v4 supports ECC memory, while the i7-4910MQ does not. This is a key differentiator for server or workstation reliability, though the data does not quantify the performance impact of ECC.

Architecture Differences

The two processors represent different architectural generations and design philosophies. The i7-4910MQ is based on Haswell, built on Intel’s 22 nm process node, with a die size of 177 mm² and 1,400 million transistors. The Xeon E3-1265L v4 is based on Broadwell-DT, using a newer 14 nm process node, with a die size of 182 mm²—slightly larger despite the smaller process. The Xeon’s transistor count is not listed, but the die size difference suggests a denser design. Both chips have 64 KB of L1 cache and 256 KB of L2 cache per core, but the i7 has 8 MB of shared L3 cache, while the Xeon has 6 MB. This is a notable reduction for the Xeon, yet it still outperforms the i7 in all benchmarks, implying that the Broadwell architecture’s efficiency compensates for the smaller cache.

The integrated graphics differ significantly. The i7 comes with Intel HD 4600, while the Xeon features Intel Iris Pro P6300, which is a more powerful integrated GPU. The Xeon also supports ECC memory, a feature absent on the i7, making it suitable for error-sensitive workloads. Both chips support DDR3 memory in a dual-channel configuration, but the Xeon has a higher memory bandwidth of 29.9 GB/s versus the i7’s 25.6 GB/s. The Xeon’s market segment is Server/Workstation, while the i7 is Mobile, which explains the socket differences: the Xeon uses Socket 1150, the i7 uses Socket G3. Both have PCIe Gen 3 with 16 lanes, and neither has an unlocked multiplier.

Specification Differences

The most obvious difference is the socket: the i7-4910MQ uses Intel Socket G3, while the Xeon E3-1265L v4 uses Intel Socket 1150. This alone determines compatibility—the i7 is designed for laptops, the Xeon for desktop or server boards. Clock speeds differ as well: the i7 has a base clock of 2.90 GHz and boost of 3.90 GHz, while the Xeon runs at 2.30 GHz base and 3.30 GHz boost. Despite lower clocks, the Xeon has a lower TDP of 35 watts versus the i7’s 47 watts, making it more power-efficient. The process node differs (22 nm vs. 14 nm), and the L3 cache is larger on the i7 (8 MB vs. 6 MB). The Xeon supports ECC memory, the i7 does not. Integrated graphics are different (HD 4600 vs. Iris Pro P6300). The Xeon has higher memory bandwidth (29.9 GB/s vs. 25.6 GB/s). The i7 has a launch MSRP of $570, while the Xeon’s is $417. The i7 was released in January 2014, the Xeon in June 2015. The Xeon’s die size is 182 mm², the i7’s is 177 mm². The i7’s transistor count is 1,400 million; the Xeon’s is not listed.

The Verdict

Based strictly on the benchmark data, the Intel Xeon E3-1265L v4 is the superior performer. It wins all six head-to-head Cinebench tests, with margins ranging from 9.8 to 10.7 percent. The Xeon achieves this while consuming less power (35 W TDP versus 47 W) and supporting ECC memory, making it the more capable processor for both performance and reliability. The i7-4910MQ’s higher clock speeds and larger L3 cache do not translate into benchmark wins. The only area where the i7 appears competitive is its average benchmark score of 1716, which is 0.4 percent higher than the Xeon’s 1709—but this is skewed by Geekbench results that are not part of the head-to-head comparison. For anyone choosing between these two, the data clearly favors the Xeon, unless the mobile socket (G3) is a hard requirement. The Xeon’s lower launch MSRP of $417 versus $570 further reinforces its position, though pricing should not be the primary consideration given the performance gap.

Where Each One Wins

The Xeon E3-1265L v4 wins every workload category in the head-to-head data: multi-core and single-core Cinebench R15, R20, and R23. This makes it the clear choice for rendering, video encoding, or any multi-threaded application, as well as single-threaded tasks that rely on per-core performance. Its ECC memory support and server/workstation market segment suggest it is intended for reliable, long-running compute tasks. The i7-4910MQ, despite losing all benchmarks, has its own niche: it is a mobile processor on Socket G3, meaning it is the only option for laptop upgrades or mobile workstations. Its higher base and boost clocks (2.90 GHz and 3.90 GHz) might offer better responsiveness in short bursts, but the data does not show this in any benchmark. The i7’s larger 8 MB L3 cache could theoretically help in cache-sensitive workloads, but the Cinebench results do not reflect this advantage. In practical terms, the Xeon wins on raw performance and efficiency, while the i7’s only clear win is its mobile form factor. The Xeon’s Iris Pro P6300 graphics are also a step up from the HD 4600, though no graphics benchmarks are provided to quantify this. Ultimately, the Xeon is the better chip for stationary compute tasks, and the i7 is the only choice for portable systems.
