AMD Ryzen 7 3750H vs Intel Xeon E3-1265L v4 Comparison

The Intel Xeon E3-1265L v4 and the AMD Ryzen 7 3750H are both 4-core, 8-thread, 35W parts, but they target completely different worlds: one is a server/workstation chip from 2015, the other a mobile processor from 2019. The benchmark data shows a clear split: the AMD chip wins the older Cinebench R15 tests and single-core performance, while the Intel chip dominates the newer Cinebench R23 multi-core test. The Ryzen 7 3750H is the better all-rounder for everyday and single-threaded work, but the Xeon E3-1265L v4 shows surprising strength in the most demanding modern multi-core workload tested.

The Verdict

Choose the AMD Ryzen 7 3750H if you need balanced performance across both single-threaded and multi-threaded applications. The data shows it wins 3 out of 4 head-to-head benchmark comparisons, including decisive victories in Cinebench R15 multi-core (734 vs 595, a 23.4% advantage) and R15 single-core (144 vs 84, a 71.4% advantage). It also leads in R23 single-core by 16.4% (971 vs 834). Its 4.00 GHz boost clock, compared to the Intel's 3.30 GHz, explains much of this dominance. This is the chip for users who value responsiveness in everyday tasks, light gaming, and applications that rely on single-thread speed.

Choose the Intel Xeon E3-1265L v4 if your workload is heavily multi-threaded and uses modern instruction sets. The single most important data point is Cinebench R23 multi-core, where the Intel scores 5910 against the AMD's 3897, a massive 51.7% lead. Despite being four years older and built on a 14nm process versus the AMD's 12nm, the Xeon's larger 6 MB shared L3 cache (vs 4 MB on the AMD) and its server-grade architecture give it a significant edge in this sustained multi-core load. It also supports ECC memory, which the AMD does not, making it the only choice for systems requiring error-correcting memory.

For most users, the Ryzen 7 3750H is the more practical pick due to its superior single-core performance and consistency. The Xeon E3-1265L v4 is a niche part that only makes sense if you specifically need its multi-core R23 performance or ECC memory support.

Architecture Differences

The two processors come from different eras and design philosophies. The Intel Xeon E3-1265L v4 uses the Broadwell architecture on a 14nm process manufactured by Intel, with a die size of 182 mm². It was released in June 2015 and is now end-of-life. The AMD Ryzen 7 3750H uses the Zen+ architecture (codename Picasso) on a 12nm process from GlobalFoundries, with a larger die at 210 mm² and a massive 4,940 million transistors. It was released in January 2019 and remains active in production.

Cache configurations differ notably. The Intel has 64 KB of L1 cache and 256 KB of L2 cache per core, sharing a 6 MB L3 cache. The AMD has more L1 (96 KB per core) and L2 (512 KB per core) but less shared L3 at 4 MB. This means the Intel has a larger total last-level cache, which likely contributes to its strong multi-core showing.

Memory support is another differentiator. The Xeon uses DDR3 memory with dual-channel support and a specified memory bandwidth of 29.9 GB/s, and it supports ECC memory. The Ryzen uses DDR4 in dual-channel mode, but its memory bandwidth is not listed in the data, and it does not support ECC. The Intel also has a specific PCIe configuration (Gen 3, 16 Lanes CPU-only), while the AMD just lists "Gen 3" without lane count.

Integrated graphics also differ: the Intel carries Intel Iris Pro P6300, while the AMD features Radeon Vega 10. Neither chip has an unlocked multiplier. The market segments are clear: the Xeon is a Server/Workstation part on Intel Socket 1150, while the Ryzen is a Mobile part on AMD Socket FP5.

Head-to-Head Benchmarks

The benchmark results reveal a generational and architectural split. In Cinebench R15 multi-core, the AMD Ryzen 7 3750H wins decisively with a score of 734 against the Intel's 595, a delta of -18.9% from the Intel's perspective. This means the AMD is about 23% faster in this test. The Cinebench R15 single-core test shows an even larger gap: the AMD scores 144 versus the Intel's 84, a delta of -41.7%. That is a 71.4% performance advantage for the Ryzen, a massive difference that points to the impact of the higher boost clock and newer architecture.

The tables turn completely in Cinebench R23 multi-core. Here, the Intel Xeon E3-1265L v4 scores 5910, while the AMD manages only 3897, giving the Intel a delta of +51.7%. This is the single largest performance swing in either direction and suggests the Intel part scales much better with the R23 workload, likely due to its larger cache and more efficient core design for sustained multi-threaded operations. In Cinebench R23 single-core, the AMD reclaims its lead with a score of 971 versus 834, a delta of -14.1%, meaning the AMD is about 16.4% faster.

Looking at the broader benchmark averages, the two chips are remarkably close. The Intel Xeon has an average benchmark score of 1709, while the AMD Ryzen sits at 1690, a difference of only 1.1%. This explains why both chips land at the 40th percentile among all CPUs. The Intel's nearest rivals by average score are the Intel Xeon E5-1620 v3 (identical at 1709), the Intel Core i7-990X (1713, -0.2%), the AMD Ryzen 7 PRO 2700U (1715, -0.4%), and the Intel Core i7-4910MQ (1716, -0.4%). The AMD's nearest rivals include the Intel Core i7-3770K (1688, +0.1%), the Intel Core i7-980 (1693, -0.1%), the Intel Core i7-5850HQ (1688, +0.1%), and the Intel Core i5-4690K (1682, +0.5%). Both chips are effectively in the same performance tier overall, but they get there through very different strengths.
