Intel Core i5-5675R vs Intel Xeon E3-1240L v5 Comparison

Intel Core i5-5675R and Intel Xeon E3-1240L v5 are two very different Intel parts from overlapping release windows, and the benchmark data shows a clear overall winner. The Xeon E3-1240L v5 wins every recorded benchmark, but the two chips target entirely different use cases, one being a desktop processor with strong integrated graphics, the other being a low-power server chip with ECC memory support. The database records show the i5-5675R sitting at the 40th percentile of all CPUs, with an average benchmark score of 1648 points, while the Xeon E3-1240L v5 lands just one percentile lower at 39th place with an average of 1609 points. Despite the Xeon's victory in the head-to-head tests, the overall average scores and percentiles remain remarkably close, indicating that the margin between them is thin in aggregate, around a 0.1 to 0.7 percent difference from its nearest rivals.

FAQ

Q: Which CPU has the higher base clock speed, the i5-5675R 3.10 GHz, or the Xeon E3-1240L v5 2.10 GHz, and does this matter?

A: The i5-5675R has a base clock of 3.10 GHz, and the Xeon E3-1240L v5 runs at a 2.10 GHz base clock. The 1.00 GHz difference is significant on paper, but the Xeon still wins every single-core benchmark, so its lower base frequency does not translate to a deficit in practice.

Q: How many cores and threads does each processor offer?

A: The i5-5675R has 4 cores and 4 threads, while the Xeon E3-1240L v5 has 4 cores and 8 threads, making the Xeon the only one with simultaneous multithreading. The 4 extra threads give the Xeon a clear advantage in multi-core workloads, winning the multi-core Cinebench tests by 14.9 percent margins consistently.

Q: Is ECC memory supported on either CPU?

A: The Xeon E3-1240L v5 supports ECC memory support, while the i5-5675R does not. This is a key distinction for anyone building a reliable server or workstation that needs error-correcting memory, since the i5-5675R is limited to non-ECC DDR3 memory.

Q: What integrated graphics does each processor have?

A: The i5-5675R comes with Iris Pro Graphics 6200, and the Xeon E3-1240L v5 has no integrated graphics. The i5-5675R's integrated graphics work for a desktop setup without a discrete GPU, while the Xeon requires a separate graphics card and relies on its PCIe Gen 3, 16 lanes connection.

Q: What is the production status of each part?

A: The i5-5675R is marked as Active in the database, and the Xeon E3-1240L v5 is listed as End-of-life. For long-term system planning, the i5-5675R may be easier to source new, while the Xeon is likely limited to used or used channels.

The Verdict

The data suggests that the Xeon E3-1240L v5 belongs in a server or workstation build where the 8 threads, ECC memory support, and low power draw are the priorities. Every recorded benchmark result in the database favors the Xeon across the board, from the Cinebench R15 single-core 560 points versus the i5-5675R 476 points, to the R23 multi-core 5564 versus 4733 points. A builder needing a 25W TDP CPU for always-on operation and ECC support should pick the Xeon without hesitation. On the other hand, the i5-5675R is for a desktop user who needs Iris Pro Graphics 6200 integrated graphics and a 3.60 GHz boost clock, but who does not need ECC memory support. The i5-5675R's 4 threads cap its multi-core output at 1987 points in Cinebench R20, making it usable for lighter multi-core work. The desktop i5-5675R has a clear fit for a compact desktop PC where integrated graphics matter. The Xeon E3-1240L v5, with its 8 threads and 5564 points in Cinebench R23, is the better tool for server workloads and is a 14.9 percent margin over the i5-5675R in multi-core tests. If you want a specific benchmark winner, take the Xeon E3-1240L v5 every time. If you want Intel's integrated graphics, the i5-5675R is the only option, since the Xeon lacks integrated graphics entirely.

Neither chip is a top-tier performer on the percentile charts, the i5-5675R at 40th percentile and the Xeon at 39th percentile, and the recorded data shows both are mid-range processors with average scores within 0.3 percent of each other. The Xeon E3-1240L v5 edges out the i5-5675R in all six benchmark metrics, but the gap is not enormous, with the largest margin being 15 percent in Cinebench R15 multi-core. The i5-5675R has launch MSRP $265, and the Xeon E3-1240L v5 has launch MSRP $278.

Head-to-Head Benchmarks

The Xeon E3-1240L v5 wins every single head-to-head benchmark recorded in the database, making this a one-sided comparison. In Cinebench R15 multi-core, the Xeon scores 560 versus the i5-5675R's 476, a 15 percent difference. The R15 single-core test sees the Xeon at 78 points against 67 for the i5, a 14.1 percent lead. Moving to Cinebench R20 multi-core, the Xeon posts 2336 points compared to the i5-5675R's 1987 points, a 14.9 percent margin. In the R20 single-core run, the Xeon scores 329 versus 280, also 14.9 percent ahead. The Cinebench R23 multi-core result shows the Xeon at 5564 and the i5 at 4733, a 14.9 percent advantage. Finally, the R23 single-core test has the Xeon at 785 points over the i5-5675R's 668 points, again a 14.9 percent difference. Across all six tests, the Xeon maintains a consistent lead of roughly 14 to 15 percent, demonstrating that its 8 threads and Skylake architecture give it a measurable performance edge over the 4-thread Broadwell desktop chip.

The overall benchmark averages reflect a similar but less dramatic story. The i5-5675R has an average benchmark score of 1648, and the Xeon E3-1240L v5 averages 1609, a difference that puts the i5-5675R slightly higher in the aggregate scoring. This happens because the i5-5675R has Geekbench multicore score of 3738 points, adding to its overall average, while the Xeon's higher-threaded performance in Cinebench tests is offset by a lower Geekbench showing. The overall average has the i5-5675R at 40th percentile and Xeon at 39th percentile, so they sit near each other in the global ranking. Nonetheless, if you look specifically at Cinebench, the Xeon wins those tests consistently, with the i5's best result being 4733 points in R23 multi-core and 668 points in single-core, versus the Xeon's 5564 and 785 points, respectively, and the Xeon always having the higher score.

Where Each One Wins

The Xeon E3-1240L v5 wins every benchmark in the database, with all 6 head-to-head wins going in its favor. Specifically, the Xeon wins in Cinebench R15 multi-core with a 15 percent lead over the i5-5675R, and in Cinebench R15 single-core with a 14.1 percent lead. The Xeon E3-1240L v5 also wins R20 multi-core with a 14.9 percent margin, R20 single-core 14.9 percent, R23 multi-core 14.9 percent, and R23 single-core 14.9 percent. Across the board, the Xeon E3-1240L v5 consistently outperforms the i5-1240L v5, with the largest win being the Xeon E3-1240L v5 in Cinebench R15 multi-core 560 to 476. The Xeon E3-1240L v5's wins come from its 8 threads, 8 MB L3 cache, and 34.1 GB/s memory bandwidth, making it the choice for threaded workloads like video encoding or server-side rendering. In the single-core tests, the Xeon still wins despite the i5-5675R's higher 3.60 GHz boost clock, indicating the Skylake architecture's efficiency and power optimization deliver better results per clock.

The i5-5675R does not win any benchmark in the head-to-head comparison. Instead, its wins are in areas not measured by the Cinebench benchmarks: it has Iris Pro Graphics 6200 integrated graphics, while the Xeon has no integrated graphics, so any system needing graphics output without a discrete GPU must choose the i5-5675R. The i5-5675R also has a higher boost clock at 3.60 GHz versus the Xeon's 3.20 GHz, a larger TDP budget of 65W versus 25W, and an Active production status, which could make it easier to source and service. The i5-5675R has a 40th percentile rank versus the Xeon's 39th percentile, meaning the i5-5675R is slightly better positioned in the overall CPU landscape. For a desktop build that values integrated graphics and a conventional socket, the i5-5675R is the sensible pick, but for raw benchmark performance in threaded and single-threaded tasks, the data overwhelmingly favors the Xeon E3-1240L v5, which wins all 6 head-to-head tests.
