Intel Core i5-1035G4 vs Intel Xeon E5-2608L v3 Comparison

Head-to-Head Benchmarks

The benchmark data records a clean sweep for the Intel Core i5-1035G4, which wins all six head-to-head Cinebench comparisons against the Intel Xeon E5-2608L v3. The margins are consistent and narrow, ranging from 1.1% to 1.7% depending on the test and workload type. This is not a case of one processor dominating another by a wide margin; instead, the mobile Ice Lake part edges out the older server chip in every single metric.

In multi-core workloads, the i5-1035G4 holds a steady advantage. The Cinebench R15 multi-core test shows the i5 scoring 648 points against the Xeon's 637, a 1.7% lead. That same 1.7% delta appears again in Cinebench R20 multi-core, where the i5 posts 2703 versus the Xeon's 2658, and once more in Cinebench R23 multi-core, with 6436 against 6329. The consistency of that 1.7% margin across three generations of the Cinebench test suggests the performance gap is structural rather than workload-dependent.

Single-core results follow a similar pattern, though the deltas are slightly smaller. The i5-1035G4 scores 91 in Cinebench R15 single-core, just 1.1% ahead of the Xeon's 90. In Cinebench R20 single-core, the i5 posts 381 versus 375, a 1.6% edge. The Cinebench R23 single-core test shows 908 against 893, again a 1.7% margin. These are tight races, but the i5 wins every one of them.

It is notably both processors sit at the 42nd percentile among all CPUs in the database, meaning they are statistically anchored at the same performance tier. The average benchmark scores reflect this: the i5-1035G4 averages 1861 points, while the Xeon E5-2608L v3 averages 1830. The Xeon's nearest rivals include the Intel Xeon D-1537 with a delta of 0% and the Intel Core i5-8305G at 0%, while the i5's nearest rivals include the Intel Core i3-9350K at -0.3% and the Intel Core i5-7600 at +0.9%. Neither chip is breaking new ground against its peers; they are simply very close to each other.

Architecture Differences

The two processors come from different eras and are built for different purposes. The Intel Core i5-1035G4 uses the Ice Lake architecture, specifically the Ice Lake-U codename, fabricated on Intel's 10 nm process with a die size of 123 mm². It belongs to the Core i5 generation built on the Sunny Cove-U microarchitecture. The Intel Xeon E5-2608L v3, by contrast, uses the older Haswell architecture, specifically Haswell-EP, on a 22 nm process with a much larger die at 356 mm² and 2,600 million transistors.

Core counts differ in an interesting way. The Xeon has six physical cores but only six threads, meaning no Hyper-Threading support. The i5 has four physical cores but eight threads, thanks to simultaneous multithreading. This gives the i5 a thread-count advantage (8 versus 6) despite having fewer physical cores. In multi-core Cinebench tests, the i5's extra threads appear to compensate for its two-core deficit, allowing it to take the win.

Cache configurations also diverge. The i5-1035G4 has 80 KB of L1 cache per core and 256 KB of L2 cache per core, with 6 MB of shared L3 cache. The Xeon has 64 KB of L1 per core and the same 256 KB of L2 per core, but a much larger 15 MB of shared L3 cache. Despite having 2.5 times the L3 capacity, the Xeon still loses in every benchmark, suggesting that raw cache size is not the deciding factor here.

Memory architecture is another clear separation point. Both support DDR4, but the i5 uses a dual-channel memory bus with 51.2 GB/s of bandwidth, while the Xeon uses a quad-channel bus with 59.7 GB/s. The Xeon also supports ECC memory, while the i5 does not. The Xeon offers Gen 3 PCIe with 40 lanes (CPU only), while the i5 offers Gen 3 PCIe without a lane count listed in the data. The Xeon's higher memory bandwidth and ECC support point to its server/workstation heritage, yet they do not translate into benchmark wins in this comparison.

The i5 integrates Iris Plus graphics, while the Xeon has no integrated graphics at all. The i5 is a mobile part with a 15 W TDP, while the Xeon is a server/workstation part with a 52 W TDP. The Xeon was released in September 2014 and is now end-of-life, while the i5 was released in July 2019 and remains active in production.

FAQ

Q: Which processor wins in multi-core performance?

A: The Intel Core i5-1035G4 wins all three multi-core Cinebench tests. It scores 648 versus 637 in R15, 2703 versus 2658 in R20, and 6436 versus 6329 in R23, each with a 1.7% delta.

Q: Does the Xeon's six-core count give it an advantage?

A: No. The Xeon has six cores but only six threads, while the i5 has four cores and eight threads. The i5's extra threads appear to offset the Xeon's two additional physical cores, as the i5 wins every multi-core test.

Q: Which processor has better single-core performance?

A: The i5-1035G4 wins all three single-core tests. It scores 91 versus 90 in R15, 381 versus 375 in R20, and 908 versus 893 in R23, with deltas between 1.1% and 1.7%.

Q: How do these processors compare to their peers in the database?

A: Both sit at the 42nd percentile among all CPUs. The i5 averages 1861 points, with its closest rival being the Intel Core i3-9350K at -0.3%. The Xeon averages 1830 points, with the Intel Xeon D-1537 matching it at 0%.

Q: Does the Xeon's larger L3 cache help in benchmarks?

A: The Xeon has 15 MB of shared L3 cache versus the i5's 6 MB, yet it still loses every benchmark. The data suggests that cache size alone does not determine performance in these Cinebench workloads.

Q: What about memory bandwidth and ECC support?

A: The Xeon offers quad-channel memory with 59.7 GB/s bandwidth and ECC support, while the i5 offers dual-channel with 51.2 GB/s and no ECC. Despite the Xeon's memory advantages, it trails the i5 in all recorded tests.

The i5 is built on a 10 nm process with a 123 mm² die, while the Xeon uses a 22 nm process with a 356 mm² die and 2,600 million transistors. The i5 has 80 KB of L1 per core and 6 MB of shared L3, while the Xeon has 64 KB of L1 per core and 15 MB of shared L3. Both have 256 KB of L2 per core.

Memory support differs in channel count and bandwidth: the i5 uses dual-channel with 51.2 GB/s, the Xeon uses quad-channel with 59.7 GB/s. The i5 does not support ECC memory, the Xeon does. The i5 has integrated Iris Plus graphics, the Xeon has none. The i5 is a mobile part, the Xeon is a server/workstation part. The i5 is active in production, the Xeon is end-of-life.

Where Each One Wins

The Intel Core i5-1035G4 wins in every measured benchmark category. It is faster in all six Cinebench tests, covering both single-core and multi-core workloads across R15, R20, and R23 versions. For users running Cinebench-like rendering tasks, the i5 is the better choice despite its lower TDP and fewer physical cores. Its 8-thread configuration clearly helps in threaded workloads, and its newer 10 nm architecture delivers a small but consistent edge in single-threaded performance.

The Intel Xeon E5-2608L v3 does not win any benchmark in this comparison, but it holds advantages in areas that matter outside of raw Cinebench scores. It supports ECC memory, which is critical for error-sensitive server and workstation environments. It offers quad-channel memory with higher bandwidth at 59.7 GB/s. It has a larger 15 MB L3 cache and six physical cores, which may benefit specific workloads not represented in these tests. Its 40 PCIe Gen 3 lanes (CPU only) and server-grade Socket 2011-3 platform position it for multi-socket or high-expansion systems.

For mobile or low-power deployments, the i5-1035G4 is the clear winner: it consumes 15 W versus the Xeon's 52 W, includes integrated Iris Plus graphics, and still outperforms the Xeon in every recorded benchmark. For server racks where ECC, memory bandwidth, and physical core count take precedence over single-thread speed, the Xeon retains a functional role, but the data shows it cannot match the i5 in Cinebench performance. The i5's six benchmark wins and the Xeon's zero wins make the outcome unambiguous in this head-to-head.
