Intel Core i7-1195G7 vs Intel Xeon E5-4620 v3 Comparison

The Intel Xeon E5-4620 v3 and the Intel Core i7-1195G7 are two fundamentally different processors that happen to land in the same performance bracket. The Xeon is a 10-core, 20-thread Haswell-EP server chip from 2015, while the i7 is a 4-core, 8-thread Tiger Lake-U mobile part from 2021. In the head-to-head Cinebench tests, the Xeon wins all six matchups, but the margins are razor-thin—never exceeding 1.7%. The i7-1195G7 has a higher average benchmark score (2638 vs. 2587), yet the Xeon's 49th percentile ranking matches the i7's 49th percentile, placing both squarely in the mid-range of all CPUs. The verdict hinges on platform priorities: the Xeon is for legacy servers needing ECC memory and 40 PCIe Gen 3 lanes, while the i7 is for compact, power-efficient mobile systems with integrated Iris Xe graphics.

The Verdict

The data paints a clear picture of two chips that deliver nearly identical Cinebench throughput but serve opposite markets. The Intel Xeon E5-4620 v3 wins all six head-to-head benchmarks, but its largest advantage is a mere 1.7% in Cinebench R20 and R23 single-core tests. The Intel Core i7-1195G7 counters with a higher average benchmark score of 2638, edging out the Xeon's 2587, and it does so with 4 cores and 8 threads versus the Xeon's 10 cores and 20 threads. This means the i7 achieves comparable multi-core scores with far fewer physical resources, relying on higher clocks (5.00 GHz boost vs. 2.60 GHz) and a newer 10 nm process.

Choose the Xeon E5-4620 v3 if your workload demands ECC memory support, quad-channel DDR4 bandwidth of 59.7 GB/s, or 40 PCIe Gen 3 lanes from the CPU. It is a server/workstation part with a 105 W TDP and a 356 mm² die, designed for socket 2011-3 systems. Choose the Core i7-1195G7 if you need a mobile processor with integrated Iris Xe-LP Graphics G7 96EU, a 28 W TDP, and support for DDR4, LPDDR4, and LPDDR4X memory. The i7's dual-channel memory bus is a limitation for bandwidth-heavy tasks, but its 10 nm Willow Cove architecture delivers modern features absent from the Haswell-era Xeon.

Neither chip is a clear winner on raw compute. The Xeon's 6-0 sweep in head-to-head tests is statistically insignificant given the sub-2% deltas. The i7's higher average score suggests it is the more balanced performer across a broader benchmark suite, but the Xeon's server-grade features make it irreplaceable for specific enterprise builds. The i7's launch MSRP is $426, while the Xeon's is $1668, though both are end-of-life products.

Where Each One Wins

The Xeon E5-4620 v3 wins every Cinebench test in the head-to-head comparison, but the margins are minimal. Its best performance comes in single-core workloads: it leads by 1.7% in both Cinebench R20 single-core (530 vs. 521) and Cinebench R23 single-core (1263 vs. 1242). In multi-core tests, it leads by a consistent 1.6% across R15 (901 vs. 887), R20 (3757 vs. 3697), and R23 (8946 vs. 8803). These wins come from the Xeon's 10 cores and 20 threads, which provide more parallel execution resources even at lower clock speeds.

The Core i7-1195G7 wins where the Xeon cannot compete: platform mobility and integrated features. It has a 28 W TDP versus the Xeon's 105 W, making it suitable for thin-and-light laptops. It includes integrated Iris Xe-LP Graphics G7 96EU, whereas the Xeon has no integrated graphics. The i7 supports PCIe Gen 4 with 16 lanes, a newer standard than the Xeon's PCIe Gen 3 with 40 lanes. For memory, the i7 accepts DDR4, LPDDR4, and LPDDR4X, though only in dual-channel mode, while the Xeon is limited to DDR4 but in quad-channel configuration. The i7's higher boost clock of 5.00 GHz compared to the Xeon's 2.60 GHz explains how it stays competitive with fewer cores.

Geekbench data is only available for the i7, showing a multi-core score of 4248 and a single-core score of 1584. This absence in the Xeon's benchmark set means the i7 has a broader proven capability in general-purpose computing tasks, while the Xeon's data is confined to Cinebench rendering workloads.

Architecture Differences

The two processors are separated by six years of Intel architecture evolution. The Xeon E5-4620 v3 uses the Haswell-EP architecture, built on Intel's 22 nm process with 2,600 million transistors on a 356 mm² die. The Core i7-1195G7 uses the Tiger Lake-U architecture, specifically Willow Cove-U, on a 10 nm process with a 144 mm² die. This process shrink allows the i7 to pack 4 cores and 8 threads into a much smaller footprint while achieving higher clock speeds.

Cache configurations differ significantly. The Xeon has 64 KB of L1 cache per core and 256 KB of L2 per core, with 25 MB of shared L3 cache. The i7 has 80 KB of L1 per core and 1.25 MB of L2 per core, with only 12 MB of shared L3. Despite the i7's larger L1 and L2 allocations per core, the Xeon's larger L3 pool (25 MB vs. 12 MB) benefits multi-threaded server workloads with more shared data.

Memory support is a major differentiator. The Xeon supports ECC memory, a critical feature for error-sensitive server applications, and uses a quad-channel memory bus with 59.7 GB/s of bandwidth. The i7 has no ECC support and uses a dual-channel bus with no published bandwidth figure. PCIe connectivity also diverges: the Xeon offers 40 Gen 3 lanes from the CPU, while the i7 offers 16 Gen 4 lanes. The i7's Gen 4 standard provides higher per-lane bandwidth, but the Xeon's lane count is far higher for expandability.

The Xeon is a server/workstation part on Intel Socket 2011-3, released on 2015-05-31 with part number SR22K. The i7 is a mobile part on Intel BGA 1449, released on 2021-05-30 with part number SRKSC. Neither has an unlocked multiplier. The Xeon's launch MSRP is $1668; the i7's is $426. Both are end-of-life, and neither has a listed series name.

Head-to-Head Benchmarks

The Xeon E5-4620 v3 sweeps the Cinebench suite, but every victory is narrow. In multi-core tests, the Xeon leads by 1.6% consistently: 901 vs. 887 in Cinebench R15, 3757 vs. 3697 in Cinebench R20, and 8946 vs. 8803 in Cinebench R23. These results show that the Xeon's 10-core, 20-thread configuration provides only a marginal throughput advantage over the i7's 4-core, 8-thread setup in rendering workloads. The i7's higher single-core clocks (5.00 GHz boost) nearly compensate for its 6-core deficit in multi-threaded tasks.

Single-core results follow the same pattern. The Xeon wins Cinebench R15 single-core 127 to 125, a 1.6% margin. In Cinebench R20 single-core, it wins 530 to 521, a 1.7% margin. In Cinebench R23 single-core, it wins 1263 to 1242, another 1.7% margin. These are the largest deltas in the entire head-to-head, yet they remain under 2%. The Xeon's older Haswell architecture, running at much lower clocks, still edges out the newer Tiger Lake design in single-threaded Cinebench tests.

The i7-1195G7 has no wins in the head-to-head benchmark set, but its Geekbench scores (4248 multi-core, 1584 single-core) are not available for the Xeon, so direct comparison in that test is impossible. The i7's nearest rivals include the Intel Core i9-8950HK (2641 avg score, -0.1% delta) and Intel Core i7-5820K (2642 avg score, -0.1% delta), showing it performs slightly above its 2638 average. The Xeon's nearest rivals include the Intel Xeon E-2174G (2588 avg score, 0% delta) and AMD Ryzen 9 4900HS (2573 avg score, 0.5% delta), placing it in a tight cluster around its 2587 average.

The data suggests that for Cinebench rendering, the Xeon is marginally faster across the board, but the i7's advantage in average score, integrated graphics, lower TDP, and modern platform features makes it the more versatile chip for most users. The Xeon's wins are real but negligible in practical terms, and its value lies entirely in server-specific capabilities like ECC memory, quad-channel bandwidth, and 40 PCIe lanes. The i7, despite losing every head-to-head test, is the better-rounded processor for mobile and compact systems.
