Intel Core i7-1185G7E vs Intel Xeon E-2274G Comparison

The Intel Core i7-1185G7E and Intel Xeon E-2274G are both 4-core, 8-thread processors from Intel, but they occupy different corners of the market. The i7-1185G7E is a Tiger Lake-U mobile processor with a 15W TDP, while the Xeon E-2274G is a Coffee Lake-S workstation and server processor with an 83W TDP. Despite the Xeon's higher clock speeds and much larger power budget, the recorded benchmark data shows the mobile part winning every head-to-head comparison.

Head-to-Head Benchmarks

The head-to-head results are entirely one-sided. The Core i7-1185G7E wins all 8 recorded comparisons, with the Xeon E-2274G failing to take a single test. The largest margin appears in Geekbench single-core, where the i7-1185G7E scores 1756 against the Xeon's 1586, a 10.7% advantage. In Geekbench multi-core, the i7-1185G7E scores 5459 versus 5174, a 5.5% lead. These are the two most decisive results in the comparison.

The Cinebench results are far closer. In Cinebench R15 multi-core, the i7-1185G7E scores 836 against 835, a 0.1% edge. The single-core R15 test shows 118 versus 117, a 0.9% lead.

Where Each One Wins

The benchmark data is unambiguous: the Core i7-1185G7E wins all 8 head-to-head comparisons. It leads in every Cinebench test and every Geekbench test. The largest advantages are in Geekbench, where the mobile part leads by 5.5% in multi-core and 10.7% in single-core.

The Xeon E-2274G wins in areas outside raw benchmark scores. It supports ECC memory, which the i7-1185G7E does not. It provides 16 PCIe Gen 3 lanes versus 4 PCIe Gen 4 lanes. It has a listed memory bandwidth of 42.7 GB/s. It also has higher base and boost clocks, at 4.00 GHz and 4.90 GHz respectively.

The i7-1185G7E wins on power efficiency. Its 15W TDP is dramatically lower than the Xeon's 83W TDP, yet it still delivers higher benchmark scores. This makes it suitable for mobile and low-power applications where the Xeon's power draw would be prohibitive.

The Xeon E-2274G wins on platform features for server and workstation use. ECC memory support, more PCIe lanes, and a socketed form factor (Socket 1151) make it appropriate for traditional server boards. Its higher base clock of 4.00 GHz may benefit workloads that rely on sustained all-core operation at high frequencies.

The i7-1185G7E wins on cache capacity. It has 12 MB of shared L3 versus 8 MB, and larger L1 and L2 per core. This likely contributes to its benchmark advantage despite lower clock speeds.

For workloads that depend on single-threaded performance, the i7-1185G7E is the clear choice. Its 10.7% Geekbench single-core lead is the largest margin in the comparison.

For workloads that require ECC memory or many PCIe lanes, the Xeon E-2274G is the appropriate choice. Its 16 PCIe lanes and ECC support are features the i7-1185G7E cannot offer.

The average benchmark scores reinforce the i7-1185G7E's position. It averages 2703 against the Xeon's 2643, and it sits at the 50th percentile of all CPUs versus the Xeon's 49th.

In summary, the i7-1185G7E is the faster processor in every recorded benchmark, while the Xeon E-2274G offers platform features that the mobile part lacks. The choice depends on whether raw performance or platform capabilities matter more.
