Intel Core i7-4712HQ vs Intel Xeon E3-1225 v5 Comparison

The Intel Xeon E3-1225 v5 and the Intel Core i7-4712HQ are both 4-core Intel processors, but they come from different eras and target different market segments. The Xeon is a Skylake-based server and workstation chip on Socket 1151, while the i7 is a Haswell-based mobile chip on BGA 1364. The recorded head-to-head data shows a clean sweep: the Xeon wins all 6 benchmark comparisons, with margins between 12.2% and 12.5%. This analysis explores what the data implies for each chip's intended role.

The Verdict

The benchmark data is unambiguous. The Xeon E3-1225 v5 wins every single head-to-head test in the database, taking all 6 wins against 0 for the i7-4712HQ. The margins are tight and consistent, ranging from 12.2% to 12.5% across Cinebench R15, R20, and R23, in both single-core and multi-core tests.

The i7-4712HQ does have one structural advantage: it offers 8 threads versus the Xeon's 4, and it does so within a 37W TDP envelope compared to the Xeon's 80W. But the data shows that the extra threads do not translate into a multi-core win. The Xeon's higher clocks (3.30 GHz base, 3.70 GHz boost versus 2.30 GHz base, 3.30 GHz boost) and its newer Skylake architecture overcome the thread deficit.

Who should pick which? The Xeon E3-1225 v5 is the choice for a Socket 1151 server or workstation build where ECC memory support and higher memory bandwidth (34.1 GB/s versus 25.6 GB/s) matter. Its launch MSRP was $224. The i7-4712HQ, with a launch MSRP of $378, is a mobile part soldered to BGA 1364, aimed at laptops and compact systems where the 37W power budget is the priority. For raw performance, the data points squarely at the Xeon.

Architecture Differences

The two chips come from different process generations. The Xeon E3-1225 v5 is built on Intel's 14 nm process (Skylake-DT), while the i7-4712HQ uses the older 22 nm Haswell process. This shows up in the transistor and die measurements: the Xeon packs 1,750 million transistors into a 122 mm² die, while the i7 fits 1,400 million transistors into a larger 177 mm² die. The newer node gives the Xeon a density advantage.

Cache configurations also differ. Both have 64 KB of L1 and 256 KB of L2 per core, but the Xeon has 8 MB of shared L3 cache versus 6 MB on the i7. That extra 2 MB of L3 is a meaningful buffer for server-style workloads.

Memory support is a major differentiator. The Xeon supports both DDR3 and DDR4 in a dual-channel configuration, with a memory bandwidth of 34.1 GB/s. The i7-4712HQ is limited to DDR3, also dual-channel, with a lower 25.6 GB/s bandwidth. The Xeon also supports ECC memory; the i7 does not. For workstation reliability, that is a decisive feature.

The integrated graphics differ as well: the Xeon carries HD Graphics P530, while the i7 has Intel HD 4600. Both are end-of-life products, but the Xeon was released on 2015-10-18, after the i7's 2014-03-31 release. The part numbers are SR2LJ for the Xeon and SR1PZ for the i7.

Where Each One Wins

The head-to-head table shows the Xeon winning all 6 recorded comparisons. That covers Cinebench R15, R20, and R23, each with both multi-core and single-core variants. The Xeon's multi-core wins are notable because the i7 has twice the thread count. The Xeon's single-core wins are equally decisive, reflecting its higher boost clock of 3.70 GHz versus 3.30 GHz.

The i7-4712HQ does not win any head-to-head benchmark, but it has strengths that the data captures indirectly. Its 37W TDP is less than half the Xeon's 80W, which makes it suitable for thermally constrained mobile designs. It also has recorded Geekbench scores in the database: 2734 multi-core and 923 single-core. The Xeon has no Geekbench entry, so a direct comparison on that test is not possible from the recorded data.

Looking at the nearest rivals in the database provides context. The Xeon E3-1225 v5 sits at an average benchmark score of 1465, with a 38th percentile ranking. Its closest competitor is the Intel Core i7-4710HQ at 1473, which is 0.5% ahead of the Xeon. That is a curious data point: a mobile i7 chip edges out the Xeon in average score, even though the Xeon beats the i7-4712HQ in every head-to-head test. The Xeon is also 0.2% ahead of the i3-7350K (1462), 0.3% ahead of the Ryzen 3 PRO 2200GE (1461), and 0.6% ahead of the Xeon E3-1515M v5 (1456).

The i7-4712HQ has an average score of 1436 and a 37th percentile ranking. Its nearest rivals include the AMD Ryzen 5 2400G at 1439 (0.2% ahead of the i7), the Intel Core i7-2600K at 1433 (0.2% behind), the AMD Ryzen 3 2200GE at 1444 (0.6% ahead), and the Intel Xeon E3-1505L v5 at 1446 (0.7% ahead). The i7-4712HQ is the lower-scoring chip in this comparison, and its nearest-rival list shows it clustered with older and lower-power parts.

FAQ

Q: Which CPU is faster in multi-core rendering?

A: The Xeon E3-1225 v5 wins all three multi-core tests: Cinebench R15 (510 versus 454, 12.3% ahead), R20 (2127 versus 1895, 12.2% ahead), and R23 (5065 versus 4512, 12.3% ahead).

Q: Does the i7-4712HQ's 8 threads give it an advantage?

A: No. Despite having 8 threads against the Xeon's 4, the i7 loses every multi-core test in the head-to-head data. The Xeon's higher clocks and newer architecture compensate for the thread deficit.

Q: Which CPU supports ECC memory?

A: Only the Xeon E3-1225 v5. The database lists ECC memory support as true for the Xeon and false for the i7-4712HQ.

Q: Which chip draws less power?

A: The i7-4712HQ, with a 37W TDP versus the Xeon's 80W. This makes the i7 better suited to mobile and low-power designs.

Q: Which processor is newer?

A: The Xeon E3-1225 v5, released on 2015-10-18, versus the i7-4712HQ's 2014-03-31 release.

Q: What sockets do these CPUs use?

A: The Xeon uses Intel Socket 1151, while the i7-4712HQ uses Intel BGA 1364, which is a soldered mobile socket.

Head-to-Head Benchmarks

The head-to-head data is remarkably consistent. In Cinebench R15 multi-core, the Xeon scores 510 against the i7's 454, a 12.3% advantage. In R15 single-core, the Xeon scores 72 against 64, a 12.5% edge. The pattern holds in R20: multi-core is 2127 versus 1895 (12.2% ahead), and single-core is 300 versus 267 (12.4% ahead). R23 shows the same story: multi-core 5065 versus 4512 (12.3% ahead), single-core 715 versus 637 (12.2% ahead).

The narrow spread of margins, from 12.2% to 12.5%, suggests a consistent per-clock or per-IPC advantage rather than a workload-specific quirk. The Xeon's boost clock is 3.70 GHz versus 3.30 GHz, a raw clock advantage that closely tracks the observed benchmark deltas. The single-core results in particular align with the clock difference, while the multi-core results show the Xeon maintaining its lead even when the i7's extra threads should help.

The i7-4712HQ's best showing is in R23 multi-core, where it reaches 4512, but the Xeon still beats it by 12.3%. The i7's worst relative result is R15 single-core, where it trails by 12.5%. Across all six tests, the Xeon's smallest margin is 12.2% and its largest is 12.5%, a remarkably tight band.
