Intel Core i7-1185G7E vs Intel Xeon E5-4650 v3 Comparison

Head-to-Head Benchmarks

The benchmark data presents an unusually consistent picture: the Intel Xeon E5-4650 v3 wins every single head-to-head comparison in the database, across all six recorded tests. There is no benchmark where the Intel Core i7-1185G7E comes out ahead. The margins, however, are remarkably narrow given the architectural gulf between the two processors.

In Cinebench R15 multicore, the Xeon scores 928 against the Core i7's 836, a delta of -9.9% from the perspective of the mobile chip. The single-core test tells the same story: 131 versus 118, again a 9.9% gap. Moving to Cinebench R20, the Xeon posts 3869 multicore and 546 single-core, while the Core i7 manages 3487 and 492 respectively. The delta remains pinned at -9.9% for both. Cinebench R23 shows the Xeon at 9212 multicore and 1300 single-core, against 8303 and 1172 for the Core i7, with the multicore gap at -9.9% and the single-core gap slightly tighter at -9.8%.

The consistency of these margins is striking. Across six tests, the Xeon's advantage never deviates beyond a single tenth of a percentage point. This suggests the performance difference is structural rather than workload-dependent, a product of the fundamental design choices in each chip rather than a quirk of any particular rendering workload.

The average benchmark scores tell a similar but slightly different story. The Core i7-1185G7E averages 2703 across its recorded benchmarks, placing it at the 50th percentile of all CPUs in the database. Its nearest rivals include the Intel Xeon E5-2640 v3 at an identical 2703 average, the Core i7-8700T at 2701, the Core i5-1345UE at 2698, and the Xeon E-2226G at 2709. The Xeon E5-4650 v3 averages 2664, also at the 50th percentile, with nearest rivals including the Core i7-9750HF at 2662, the Core i7-9700T at 2668, the Core i5-9500F at 2670, and the Core i7-1365UE at 2677.

Here an interesting inversion appears. Despite winning every head-to-head test, the Xeon E5-4650 v3 actually has a lower average benchmark score than the Core i7-1185G7E, 2664 versus 2703. This is because the Core i7's recorded benchmark set includes Geekbench results, where it scores 5459 multicore and 1756 single-core, tests that are absent from the Xeon's recorded data. The average score aggregates across different test batteries, so it does not directly contradict the head-to-head sweep.

The head-to-head comparison, however, is unambiguous. The Xeon E5-4650 v3 wins six out of six tests, with the Core i7-1185G7E recording zero wins. Every margin sits between 9.8% and 9.9%.

Architecture Differences

The two processors come from entirely different eras and design philosophies. The Intel Core i7-1185G7E is built on Tiger Lake, specifically the Tiger Lake-U mobile platform, using a 10 nm process node from Intel's own foundry. Its architecture is Willow Cove, and it belongs to the Core i7 generation. The die measures 144 mm². The Intel Xeon E5-4650 v3, by contrast, uses the Haswell architecture, specifically Haswell-EP, on a 22 nm process node. Its die is substantially larger at 356 mm² and contains 2,600 million transistors, a figure not recorded for the Core i7.

Cache configurations differ markedly. The Core i7-1185G7E provides 80 KB of L1 cache per core, 1.25 MB of L2 cache per core, and 12 MB of shared L3 cache. The Xeon E5-4650 v3 provides 64 KB of L1 per core, 256 KB of L2 per core, and a much larger 30 MB of shared L3 cache. The Xeon's larger L3 reflects its server/workstation positioning and higher core count.

Integrated graphics represent a major divergence. The Core i7-1185G7E includes Iris Xe-LP Graphics G7 with 96 execution units. The Xeon E5-4650 v3 has no integrated graphics at all, which is typical for a server/workstation part that expects a discrete GPU. The Core i7's graphics capability is a meaningful differentiator for systems that need display output without an add-in card.

Memory architecture also differs. The Core i7 supports DDR4 and LPDDR4X over a dual-channel memory bus, with no ECC support. The Xeon supports DDR4 over a quad-channel bus with a recorded memory bandwidth of 68.3 GB/s, and it does support ECC memory. The Xeon's quad-channel configuration and ECC support align with its server/workstation market segment. The Core i7's PCIe implementation is Gen 4 with 4 lanes from the CPU, while the Xeon provides Gen 3 with 40 lanes from the CPU, a substantial difference in expansion capability.

Specification Differences

The core and thread counts differ sharply. The Core i7-1185G7E has 4 cores and 8 threads, while the Xeon E5-4650 v3 has 12 cores and 24 threads. The Xeon offers three times the cores and three times the threads. Clock speeds tell the opposite story. The Core i7 has a base clock of 1800 MHz and a boost clock of 4.40 GHz. The Xeon has a higher base clock of 2.10 GHz but a much lower boost clock of 2.80 GHz. The Core i7's boost advantage of 1.60 GHz over the Xeon's boost is substantial.

Thermal design power differs enormously. The Core i7-1185G7E is rated at 15 watts, while the Xeon E5-4650 v3 is rated at 105 watts. This sevenfold difference in TDP reflects the Core i7's mobile orientation and the Xeon's server/workstation role. Sockets are incompatible: the Core i7 uses Intel BGA 1449, while the Xeon uses Intel Socket 2011-3.

The process nodes differ, as noted: 10 nm for the Core i7 versus 22 nm for the Xeon. Memory support differs in channel count, bandwidth, and ECC capability. The Core i7 supports DDR4 and LPDDR4X over dual channels without ECC; the Xeon supports DDR4 over quad channels with ECC and a recorded bandwidth of 68.3 GB/s. PCIe generations and lane counts differ as well: Gen 4 with 4 lanes for the Core i7, Gen 3 with 40 lanes for the Xeon.

Market segments diverge completely. The Core i7 is a mobile part, currently in active production, released in September 2020. The Xeon is a server/workstation part, now end-of-life, released in May 2015. The Core i7 has a launch MSRP of $431. The Xeon has a launch MSRP of $2838. Production status also differs: the Core i7 is active, the Xeon is end-of-life. The part numbers are SRK0X for the Core i7 and SR22J for the Xeon. Neither processor has an unlocked multiplier.

The Verdict

The data supports a clear division of roles. The Intel Xeon E5-4650 v3 wins every head-to-head benchmark in the database, with margins between 9.8% and 9.9% across all six Cinebench tests. It also offers triple the core and thread count, ECC memory support, quad-channel memory with 68.3 GB/s of bandwidth, and 40 PCIe Gen 3 lanes. For workloads that can utilize many cores, server-grade memory, or extensive expansion, the Xeon is the stronger choice. Its 105 watt TDP and lack of integrated graphics are acceptable trade-offs in a system designed around it.

The Intel Core i7-1185G7E, despite losing every head-to-head test, holds its own in context. Its average benchmark score of 2703 is actually higher than the Xeon's 2664, and it sits at the same 50th percentile. Its boost clock of 4.40 GHz, 10 nm process, and 15 watt TDP make it suited to mobile and power-constrained environments. The integrated Iris Xe graphics with 96 execution units eliminate the need for a discrete GPU in many systems. The LPDDR4X memory support further reinforces its mobile positioning.

The production status is decisive for new deployments. The Core i7-1185G7E is active, while the Xeon E5-4650 v3 is end-of-life. For new system designs, the Core i7 is the only one of the two that remains a current product. The Xeon may still be relevant for existing socket 2011-3 platforms or for workloads that specifically require its ECC, quad-channel, and high-core-count characteristics.

Where Each One Wins

The Intel Xeon E5-4650 v3 wins in every recorded benchmark category. Its advantages are clearest in multi-threaded rendering workloads, where its 12 cores and 24 threads can be fully utilized. The Cinebench R23 multicore result of 9212 versus 8303 demonstrates this. It also wins single-core tests, though by the same narrow margin, indicating that even lightly threaded workloads run slightly faster on the older chip. Systems requiring ECC memory, quad-channel bandwidth, or 40 PCIe Gen 3 lanes will prefer the Xeon. The server/workstation market segment is its natural home.

The Intel Core i7-1185G7E wins in scenarios not captured by the head-to-head tests. Its integrated Iris Xe-LP Graphics G7 with 96 execution units provides display output without a discrete GPU, which the Xeon cannot do. Its 15 watt TDP enables fanless or low-power designs that a 105 watt processor cannot match. The LPDDR4X memory support suits compact, power-efficient laptops and embedded systems. The 4.40 GHz boost clock provides responsiveness in bursty workloads, and the Gen 4 PCIe interface offers modern connectivity despite its 4-lane limitation. The active production status and mobile market segment make it the appropriate choice for portable and power-sensitive designs, while the Xeon remains the pick for compute-heavy server or workstation deployments where its benchmark wins and platform features matter most.
