Intel Core i5-1145G7E vs Intel Xeon D-1548 Comparison

Head-to-Head Benchmarks

The recorded data shows a remarkably consistent pattern across all six Cinebench tests: the Intel Xeon D-1548 wins every single benchmark, but by margins that are surprisingly narrow given the architectural gap. The largest advantage appears in Cinebench R15 single-core, where the Xeon D-1548 scores 109 against 106 for the Core i5-1145G7E, a delta of 2.8%. Every other test lands within a tight 2.6% to 2.7% band.

In multi-core workloads, the Xeon D-1548 posts 777 in R15 versus 757, a 2.6% win. The R20 multi-core result shows 3239 against 3156, again 2.6%. R23 multi-core follows the same script with 7713 versus 7516. Single-core results are nearly identical in relative terms: R20 gives 457 against 445 (2.7%), and R23 gives 1089 against 1061 (2.6%).

What makes this interesting is the hardware underneath. The Xeon D-1548 is an 8-core, 16-thread Broadwell part with a 2.00 GHz base clock and 2.60 GHz boost. The Core i5-1145G7E is a 4-core, 8-thread Tiger Lake-U chip with a 1.50 GHz base and 4.10 GHz boost. The Xeon has double the cores and threads, yet it only manages a 2.6% lead in multi-core tests. The Core i5 compensates for its half the core count with a much higher boost clock and a newer architecture.

The single-core picture is even more telling. A server Xeon from 2015 with a 2.60 GHz boost beats a 2020 mobile chip with a 4.10 GHz boost in every single-core test. The deltas are small, between 2.6% and 2.8%, but they are consistent. This suggests the Broadwell architecture retains enough single-thread efficiency to hold its own, despite the massive clock disadvantage.

Looking at the broader database context, the Xeon D-1548 sits at the 47th percentile among all CPUs with an average benchmark score of 2231. Its nearest rivals include the Intel Xeon E5-4648 v3 at 2227 (0.2% slower), the Intel Xeon D-1715TER at 2238 (0.3% faster), the Intel Core i7-8559U at 2225 (0.3% slower), and the Intel Core i7-5775C at 2224 (0.3% slower). The Core i5-1145G7E also lands at the 47th percentile with an average score of 2174. Its nearest rivals are the AMD Ryzen 5 3400GE at 2175 (essentially tied), the Intel Core i7-1185GRE at 2178 (0.2% faster), the Intel Core i5-7640X at 2167 (0.3% slower), and the Intel Core i7-5950HQ at 2158 (0.8% slower).

The practical takeaway from the head-to-head numbers is that both processors occupy the same performance tier. The Xeon D-1548 is ahead, but the margin is small enough that other system characteristics will matter more in real-world use.

The Verdict

The data points to a clear but narrow winner. The Intel Xeon D-1548 wins all six recorded benchmark comparisons, with deltas ranging from 2.6% to 2.8%. If raw Cinebench performance is the only criterion, the Xeon D-1548 is the correct choice.

However, the context matters. The Xeon D-1548 is a server and workstation part with a 45 W TDP, ECC memory support, and 24 PCIe Gen 3 lanes. The Core i5-1145G7E is a mobile processor with a 28 W TDP, no ECC support, and only 4 PCIe Gen 4 lanes. The Core i5 does include integrated Iris Xe Graphics G7 80EU, while the Xeon has no integrated graphics at all.

For a system that needs ECC memory, the Xeon D-1548 is the only option between these two. For a compact or fanless build where power draw and integrated graphics matter, the Core i5-1145G7E becomes more attractive despite its slightly lower benchmark scores.

The benchmark results indicate that users who prioritize multi-threaded throughput should pick the Xeon D-1548, but they should not expect a dramatic uplift. Users who need a lighter, more integrated package can choose the Core i5-1145G7E and lose only a few percent in Cinebench performance. The decision should rest on platform requirements rather than raw speed, because the speed difference is marginal.

Specification Differences

The two processors differ significantly in their core configurations. The Intel Xeon D-1548 uses 8 cores and 16 threads, while the Intel Core i5-1145G7E uses 4 cores and 8 threads. Base clocks are 2000 MHz for the Xeon and 1500 MHz for the Core i5. Boost clocks are 2.60 GHz and 4.10 GHz respectively.

Thermal design power differs as well. The Xeon D-1548 is rated at 45 W, while the Core i5-1145G7E is rated at 28 W. This makes the Core i5 the lower-power part by a substantial margin.

Socket compatibility is completely different. The Xeon D-1548 uses Intel BGA 1667, while the Core i5-1145G7E uses Intel BGA 1449. These are not interchangeable. Memory support also diverges: the Xeon supports DDR3 and DDR4, while the Core i5 supports DDR4 and LPDDR4X. Both use dual-channel memory buses.

PCIe connectivity is another major split. The Xeon D-1548 provides Gen 3 with 24 lanes, while the Core i5-1145G7E provides Gen 4 with 4 lanes. The Xeon offers far more lanes for expansion, but the Core i5 offers a newer PCIe generation.

ECC memory support is present on the Xeon D-1548 but absent on the Core i5. Integrated graphics exist only on the Core i5, which features Iris Xe Graphics G7 80EU. The Xeon has no integrated graphics. The launch MSRP for the Xeon D-1548 is $555, and the launch MSRP for the Core i5-1145G7E is $312.

The release dates are also far apart. The Xeon D-1548 launched on 2015-10-31, while the Core i5-1145G7E launched on 2020-09-01. Part numbers are SR2DJ for the Xeon and SRK0Z for the Core i5.

Architecture Differences

The architectural divide is significant. The Xeon D-1548 uses the Broadwell architecture, specifically the Broadwell-DE generation, built on Intel's 14 nm process. The Core i5-1145G7E uses the Tiger Lake architecture, specifically the Willow Cove-U generation, built on Intel's 10 nm process. The process node advantage goes to the Core i5, which contributes to its higher boost clock and lower TDP.

Cache layouts differ substantially. The Xeon D-1548 has 64 KB of L1 per core and 256 KB of L2 per core, with 1.5 MB of L3 per core. The Core i5-1145G7E has 80 KB of L1 per core, 1.25 MB of L2 per core, and 8 MB of shared L3. The Core i5 uses a shared L3 pool, while the Xeon distributes its L3 per core.

Die size and transistor counts tell the story of the two designs. The Xeon D-1548 has a die size of 246 mm² with 3,200 million transistors. The Core i5-1145G7E has a die size of 144 mm², with no transistor count recorded in the database. The larger Xeon die reflects its 8-core server heritage, while the smaller Core i5 die benefits from the more advanced 10 nm process.

The Xeon D-1548 is marked for the server and workstation market segment, while the Core i5-1145G7E is a mobile part. This is reflected in the ECC support, the PCIe lane count, and the absence or presence of integrated graphics. Neither processor has an unlocked multiplier.

Where Each One Wins

The Xeon D-1548 wins in every recorded benchmark, but the use cases go beyond raw scores. The Xeon's 8 cores and 16 threads, combined with ECC memory support and 24 PCIe Gen 3 lanes, make it the natural fit for server and workstation tasks where data integrity and expansion matter. Its dual-channel DDR3 and DDR4 support adds flexibility for existing memory inventories. The 45 W TDP is higher than the Core i5, but acceptable for a server board.

The Core i5-1145G7E wins on platform efficiency. Its 28 W TDP, integrated Iris Xe Graphics G7 80EU, and 4 PCIe Gen 4 lanes suit compact mobile or embedded systems where space and power are constrained. The newer 10 nm process and 4.10 GHz boost clock keep it competitive in single-threaded work despite having half the cores. The LPDDR4X memory support makes it viable for low-power designs that the Xeon cannot accommodate.

For workloads that rely heavily on multi-threading, the Xeon D-1548 is the safer choice, even if the margin over the Core i5 is only around 2.6%. For workloads that need integrated graphics, lower power consumption, or the latest PCIe generation, the Core i5-1145G7E holds the advantage. The recorded data shows both processors at the 47th percentile, which means users are choosing between two similarly positioned parts. The Xeon D-1548 offers server-grade features and slightly better Cinebench scores. The Core i5-1145G7E offers a modern, efficient, graphics-equipped mobile platform. The right pick depends on the system requirements, not on benchmark supremacy.
