Intel Core i7-4910MQ vs Intel Xeon E3-1241 v3 Comparison

The Verdict

The Intel Xeon E3-1241 v3 is the outright performance winner in every recorded benchmark, taking 6 wins with zero losses against the Core i7-4910MQ. The data is unambiguous: across all three Cinebench generations, the Xeon leads by approximately 14% in both single-core and multi-core tests. The average benchmark score of 1756 for the Xeon versus 1716 for the Core i7 reflects this consistent edge, a difference of 40 points. Both processors sit at the 41st percentile among all CPUs, meaning they occupy the same overall performance tier, but the Xeon does so with a higher ceiling in every measured workload.

The Core i7-4910MQ is not without its own rationale. It is a mobile part with a 47 watt TDP, which is 33 watts lower than the Xeon's 80 watt envelope. For a laptop or compact system where thermal headroom is limited, that power advantage is the deciding factor. The Xeon, however, is the choice for anyone who can accommodate a desktop socket 1150 platform and wants the maximum compute output per thread. The Xeon also brings ECC memory support, a feature absent on the Core i7. If the workload demands error-correcting memory or sustained multi-threaded rendering, the Xeon is the only candidate. If mobility and lower power draw are non-negotiable, the Core i7 is the sole option that fits.

Architecture Differences

Both processors are built on Intel's 22 nm Haswell architecture and share the same transistor count of 1,400 million. The die sizes differ slightly, with the Xeon at 160 mm² and the Core i7 at 177 mm². Both have 4 cores and 8 threads, and both feature the identical cache hierarchy: 64 KB of L1 per core, 256 KB of L2 per core, and 8 MB of shared L3. The memory controllers are also equivalent, supporting dual-channel DDR3 with a memory bandwidth of 25.6 GB/s.

The key architectural splits are in platform positioning and support features. The Xeon E3-1241 v3 belongs to the Haswell-WS generation, targets the server and workstation segment, and uses socket 1150. The Core i7-4910MQ is a Haswell mobile chip, uses socket G3, and integrates Intel HD 4600 graphics. The Xeon has no integrated graphics, a notable distinction for systems that rely on discrete GPUs or do not need iGPU output. ECC memory support is present on the Xeon and absent on the Core i7. The PCIe implementation is identical on paper, Gen 3 with 16 lanes on CPU only, and neither processor has an unlocked multiplier.

The production status for both is end-of-life, and both are older-generation parts, with release dates in early 2014. The Xeon carries the part number SR1R4, while the Core i7 uses SR1PT. The Core i7 was released earlier, in January 2014, while the Xeon followed in May 2014.

Head-to-Head Benchmarks

The Xeon wins every head-to-head test by a margin of 14% or slightly more. In Cinebench R15 multi-core, the Xeon scores 612 against 536 for the Core i7, a delta of 14.2%. The single-core result in the same test shows 86 versus 75, a 14.7% lead. In Cinebench R20, the multi-core gap is 2550 to 2236, exactly 14%, and the single-core gap is 359 to 315, also 14%. Cinebench R23 repeats the pattern, with the Xeon at 6072 and the Core i7 at 5326 in multi-core, and 857 versus 752 in single-core, both again at 14%.

The consistency of these deltas is remarkable. Across six tests spanning three Cinebench versions, the Xeon's advantage never drops below 14% and never exceeds 14.7%. This suggests the performance difference is structural, rooted in the base clock difference of 3.50 GHz versus 2.90 GHz, rather than workload-specific behavior. The boost clocks are identical at 3.90 GHz, so the Xeon's advantage comes from its higher sustained base frequency and the desktop platform's ability to hold that state under load.

The Core i7 does have a Geekbench result in the database, scoring 3368 multi-core and 1116 single-core, but no corresponding Xeon Geekbench score is recorded, so no direct comparison is possible in that test. The average benchmark score comparison, 1756 for the Xeon and 1716 for the Core i7, confirms the trend, with the Xeon's nearest rival being the Core i7-4790T at an average of 1755, a 0% delta. The Core i7's nearest rival is the AMD Ryzen 7 PRO 2700U at 1715, also a 0% delta, meaning each chip sits at the center of its own performance cluster.

FAQ

Q: Which CPU has the higher average benchmark score?

The Intel Xeon E3-1241 v3 has an average benchmark score of 1756 across all recorded tests, while the Core i7-1241 v3-4910MQ reaches 1716 in this comparison. The Xeon leads by 40 points, a 2.3% margin.

Q: Is there any benchmark where the Core i7-4910MQ wins?

No. In the recorded head-to-head data, the Core i7 does not win any of the 6 benchmarks. It loses all six Cinebench R15, R20, and R23 tests to the Xeon by 14% to 14.2% margins in multi-core and 14% to 14.7% in single-core.

Q: Do the two processors share the same number of cores and threads?

Q: What memory features differ between the two?

The Xeon E3-1241 v3 supports ECC memory, while the Core i7-4910MQ does not support ECC memory support is false. Both use DDR3 memory support with dual-channel memory bus and memory bandwidth of 25.6 GB/s, with a 25.6 GB/s bandwidth figure identical for both parts.

**Q: Which chip has integrated graphics available? The Core i7-4910MQ includes Intel HD 4600 integrated graphics, whereas the Xeon E3-1241 v3 has no integrated graphics at all. The Xeon is a server/workstation segment part, the Core i7 is a mobile segment part.

Q: What is the TDP difference between the two? The Xeon has a TDP of 80 watts and the Core i7 has a TDP of 47 watts. The Xeon TDP is 33 watts lower in the Core i7's TDP, only 47 watts, making the Xeon 33 watts higher than the mobile part.

Q: How do I pick between the two? The Xeon E3-1241 v3 wins all 6 head-to-head benchmarks and offers ECC memory support for server or workstation use. The Core i7-4910MQ brings integrated graphics and a 47 watt TDP for mobile systems, making the choice based on platform power and graphics needs.

Where Each One Wins

The Xeon E3-1241 v3 is the pick for workstation rendering, server workloads, and any scenario where ECC memory is required. Its 14% to 14.7% lead in Cinebench R15, R20, and R23 multi-core tests means faster video exports, physics simulations, and compilation tasks. The single-core wins of 86 to 75 in R15, 359 to 315 in R20, and 857 to 752 in R23 also give it an edge in lightly threaded applications like legacy CAD tools or scripting. The Xeon's 3.50 GHz base clock against the Core i7's 2.90 GHz base means the advantage persists even when boost clocks are equal at 3.90 GHz.

The Core i7-4910MQ is the choice for mobile workstations and laptops where the 47 watt TDP is a hard ceiling. The 33 watt difference versus the Xeon's 80 watt TDP is substantial for battery life and chassis cooling. The integrated Intel HD 4600 graphics also matters for systems that want CPU-only output without a discrete GPU. The Core i7's average score of 1716 places it next to the AMD Ryzen 7 PRO 2700U at 1715, a 0% delta, showing it holds its own against contemporaries in the same performance bracket despite losing to the Xeon by 14% in every test.

For dual-channel DDR3 memory bandwidth of 25.6 GB/s, both parts are equal, so memory-heavy tasks will not differentiate the two on bandwidth alone. The Xeon's 8 MB L3 cache and 4 cores, 8 threads are identical to the Core i7's, so cache-sensitive workloads see no delta. The Xeon also matches the Core i7 on PCIe Gen 3 with 16 lanes, making GPU expansion identical in lane count and generation on both sides.

In short, if the platform is socket 1150 and power is available, choose the Xeon without hesitation. If the platform is socket G3 mobile, the Core i7 is the only functional option. The Xeon is the faster part by 14% in all head-to-head results, and the Core i7 is the lower power part with integrated graphics. The Xeon E3-1241 v3 is the verdict for performance, the Core i7-4910MQ is the verdict for mobility and 47 watt computing.
