Intel Core i5-1130G7 vs Intel Xeon E3-1260L v5 Comparison

The Intel Xeon E3-1260L v5 and Intel Core i5-1130G7 are separated by five years of silicon evolution, yet benchmark data shows they land in nearly the same performance tier. The Xeon edges out the mobile Core i5 in every single Cinebench test recorded, but the margins are razor-thin — often fractions of a percent. This is a head-to-head where architecture generation and platform philosophy matter more than raw compute output.

Head-to-Head Benchmarks

The Xeon E3-1260L v5 wins all six recorded benchmarks, but none by a meaningful margin. In Cinebench R15 multicore, the Xeon scores 707 against the i5-1130G7’s 706, a delta of just 0.1%. The single-core R15 result is a dead tie at 99 points for both chips, with a delta of 0%. Moving to Cinebench R20, the Xeon again takes multicore by 2946 to 2942 (0.1%), and single-core is identical at 415 points. The trend continues in Cinebench R23: the Xeon posts 7015 multicore versus 7006 for the i5 (0.1% delta), and 990 single-core versus 989 (0.1% delta).

These scores place both processors at the 45th percentile of all CPUs tracked, meaning they sit squarely in the mid-range of the database. The average benchmark score for the Xeon is 2029, while the i5-1130G7 averages 2026 — a gap of just 0.1% when compared directly. Interestingly, the i5-1130G7’s nearest rival list includes the Xeon E3-1260L v5 with a -0.1% delta, confirming that from a performance standpoint, these two are effectively interchangeable.

The Xeon’s wins are consistent, but they are statistical noise rather than a real performance advantage. For workloads that rely heavily on multicore throughput, the Xeon’s 707 versus 706 in R15 and 7015 versus 7006 in R23 translate to less than one percent difference in rendering times. Neither chip will feel faster than the other in blind testing. The i5-1130G7’s closest competitor, the Intel Core i5-1145GRE, scores 2025 with a 0.1% delta against the i5 — again, a negligible difference.

Architecture Differences

The architectural gap between these two is substantial. The Xeon E3-1260L v5 is built on Intel’s 14 nm Skylake-DT process, while the i5-1130G7 uses the newer 10 nm Tiger Lake-U node. The Xeon packs 1,750 million transistors into a 122 mm² die; the i5’s transistor count and die size are not recorded in the data. The Xeon features 64 KB of L1 cache per core and 256 KB of L2 per core, while the i5 doubles L1 to 96 KB per core and jumps L2 to 1.25 MB per core. Both share 8 MB of L3 cache.

The Xeon supports both DDR3 and DDR4 memory in a dual-channel configuration, with a memory bandwidth of 34.1 GB/s. The i5-1130G7 is limited to DDR4 but offers double the bandwidth at 68.3 GB/s, also dual-channel. The Xeon supports ECC memory, making it suitable for error-correcting workloads; the i5 does not. PCIe connectivity also differs: the Xeon provides Gen 3 with 16 lanes (CPU only), while the i5 offers Gen 4 with 16 lanes (CPU only), doubling the theoretical transfer rate.

The i5 includes integrated Iris Xe Graphics G7 80EU, while the Xeon has no integrated graphics listed. The Xeon is a server/workstation part on Intel Socket 1151, whereas the i5 is a mobile processor on BGA 1598. The Xeon’s base clock is 2.90 GHz with a boost of 3.90 GHz, while the i5’s base clock is listed at 1100.00 MHz (1.10 GHz) with a boost of 4.00 GHz. The i5’s dramatically lower base clock reflects its 15 W TDP versus the Xeon’s 45 W TDP — the i5 is designed for sustained low-power operation, while the Xeon can draw more power for consistent server workloads.

FAQ

Q: Which processor has a higher boost clock?

A: The Intel Core i5-1130G7 boosts to 4.00 GHz, while the Intel Xeon E3-1260L v5 boosts to 3.90 GHz.

Q: Do both processors support ECC memory?

A: No. The Xeon E3-1260L v5 supports ECC memory, but the Core i5-1130G7 does not.

Q: What is the memory bandwidth difference between the two?

A: The i5-1130G7 offers 68.3 GB/s of memory bandwidth, exactly double the Xeon’s 34.1 GB/s. Both use dual-channel memory buses.

Q: Which chip has integrated graphics?

A: Only the Core i5-1130G7 includes integrated graphics, specifically Iris Xe Graphics G7 80EU. The Xeon E3-1260L v5 has no integrated graphics listed.

Q: Are these processors in the same performance percentile?

A: Yes, both are at the 45th percentile of all CPUs tracked, and their average benchmark scores differ by only 3 points (2029 versus 2026).

Q: Which processor uses a newer PCIe standard?

A: The i5-1130G7 uses PCIe Gen 4 with 16 lanes, while the Xeon E3-1260L v5 uses PCIe Gen 3 with 16 lanes.

The Verdict

The data paints a clear picture: choose the Xeon E3-1260L v5 if you need ECC memory support, a socketed form factor, or a server/workstation platform. It wins every recorded benchmark, albeit by margins of 0.1% or less, and its 45 W TDP allows for sustained throughput in a desktop or rack environment. The Xeon’s support for both DDR3 and DDR4 memory also offers flexibility for older systems.

Choose the Core i5-1130G7 if power efficiency, integrated graphics, or memory bandwidth are your priorities. Its 15 W TDP is one-third of the Xeon’s, making it far better suited for laptops and fanless designs. The i5’s 68.3 GB/s memory bandwidth is double the Xeon’s, and its PCIe Gen 4 support future-proofs storage and GPU connectivity. The Iris Xe Graphics G7 80EU eliminates the need for a discrete GPU in basic display tasks.

For raw compute, the Xeon’s 7015 versus 7006 in Cinebench R23 multicore is effectively a tie. Neither chip will disappoint in CPU-bound tasks, but the platform differences are decisive. The Xeon is end-of-life, while the i5 remains active in production. The Xeon’s launch MSRP was $294, a figure that reflects its server positioning. The i5-1130G7 has no recorded launch MSRP. If you are building a new system today, the i5-1130G7’s active status, integrated graphics, and lower power draw make it the more practical choice — unless ECC memory is non-negotiable.
