CPU Comparison

The Intel Xeon E-2356G and the Intel Core i5-1340P are two very different processors that end up in a statistical dead heat in the database’s aggregate scoring. The Xeon E-2356G, a Rocket Lake-E server/workstation part, and the Core i5-1340P, a Raptor Lake-P mobile chip, both land at the 58th percentile against all CPUs. Their average benchmark scores are nearly identical, with the Xeon posting 4548 and the i5 posting 4545. The nearest rival data confirms the tie: the i7-10700KF sits at 4547, and the two processors are within 0.1% of each other. This is a rare case where the architecture and platform differences are far more significant than the raw performance numbers.

Head-to-Head Benchmarks

The head-to-head results show a clean sweep for the Intel Core i5-1340P, but the margins are so small that they are practically within run-to-run variance. In Cinebench R15 multi-core, the i5-1340P scores 1584 against the Xeon’s 1575, a delta of -0.6% from the Xeon’s perspective. Single-core R15 is similarly close: 223 for the i5 versus 222 for the Xeon, a -0.4% difference. Moving to Cinebench R20, the pattern holds. The i5-1340P takes multi-core with a score of 6600, while the Xeon E-2356G manages 6565, a -0.5% gap. In R20 single-core, the scores are 931 and 926 respectively, again a -0.5% margin for the Xeon to overcome.

The most comprehensive render test, Cinebench R23, continues the trend. The i5-1340P posts 15716 in multi-core, beating the Xeon’s 15632 by a -0.5% delta. In single-core R23, the i5’s 2218 edges out the Xeon’s 2206, another -0.5% difference. Across all six benchmark comparisons, the i5-1340P wins every single one, but the largest margin is a mere 0.6%. The Xeon E-2356G does not win a single head-to-head test, yet it also does not lose a single test by more than a rounding error. This is not a performance victory; it is a statistical tie that happens to favor the mobile chip in every listed metric.

The Geekbench scores are where the two diverge slightly, though these are not in the head-to-head table. The Xeon E-2356G scores 7213 in Geekbench multi-core and 2044 in single-core. The i5-1340P does not have Geekbench scores listed in the benchmark data, but its absence from that specific test does not change the overall picture. The aggregate average scores, 4548 for the Xeon and 4545 for the i5, confirm that any performance advantage is negligible. If you are choosing based purely on these benchmark numbers, you are effectively choosing between two CPUs that perform identically in synthetic workloads.

Architecture Differences

The architectural gap between these two is substantial. The Xeon E-2356G is built on Rocket Lake-E, using Intel’s 14 nm process node with a die size of 276 mm². It is a monolithic design with 6 cores and 12 threads, classified as a server/workstation part. The Core i5-1340P is based on Raptor Lake-P, fabricated on Intel’s 10 nm process node. It features a hybrid architecture with 12 cores and 16 threads, which indicates a mix of performance and efficiency cores, though the exact core layout is not specified in the data. The i5 is a mobile processor, and its die size is not listed.

Cache configuration is another major split. Both chips share an 80 KB L1 cache per core and a 12 MB shared L3 cache. However, the L2 cache differs significantly. The Xeon E-2356G has 512 KB of L2 per core, while the Core i5-1340P has 2 MB of L2 per core. This means the i5 has four times the L2 cache per core, which can be a benefit for workloads that rely on fast access to working sets. The memory support also diverges: the Xeon is limited to DDR4, while the i5 supports both DDR4 and DDR5. The Xeon has a listed memory bandwidth of 51.2 GB/s, while the i5’s bandwidth is not provided.

The integrated graphics differ as well. The Xeon E-2356G includes UHD Graphics P750, while the i5-1340P features Iris Xe Graphics 80EU. The i5’s graphics solution is generally more capable for media tasks, though the Xeon’s GPU is intended for basic display output. The process node difference, 14 nm versus 10 nm, explains some of the efficiency gap, but the Xeon’s higher TDP of 80 watts versus the i5’s 28 watts is a direct result of their intended platforms. The Xeon is a socketed part for upgradeable systems, while the i5 is a BGA part soldered to the board.

Specification Differences

Focusing only on the fields where the two differ, the specifications tell a clear story of two different market segments. The Xeon E-2356G has 6 cores and 12 threads, while the i5-1340P has 12 cores and 16 threads. The base clock is dramatically different: the Xeon runs at 3.20 GHz, while the i5’s base clock is listed as 1900.00 MHz, which is a much lower figure reflecting its mobile power target. The boost clock favors the Xeon at 5.00 GHz versus the i5’s 4.60 GHz.

The TDP is a major separator: 80 watts for the Xeon versus 28 watts for the i5. The socket is different, with the Xeon on Intel Socket 1200 and the i5 on Intel BGA 1744. The architecture and codename differ, with Rocket Lake-E versus Raptor Lake-P. The process node is 14 nm for the Xeon and 10 nm for the i5. The L2 cache per core is 512 KB for the Xeon and 2 MB for the i5. Memory support is DDR4 only for the Xeon versus DDR4 and DDR5 for the i5. The Xeon supports ECC, while the i5 does not. The memory bandwidth is 51.2 GB/s for the Xeon, with no figure listed for the i5.

The integrated graphics are different, as are the market segments: server/workstation versus mobile. The release dates differ, with the Xeon launching on 2021-09-07 and the i5 launching on 2023-01-03. The launch MSRP differs, with the Xeon at $311 and the i5 at $353. The part numbers are SRKN2 for the Xeon and SRMJ7 for the i5. The Xeon’s die size is 276 mm², while the i5’s is not listed. Both share the same PCIe configuration: Gen 4 with 20 lanes (CPU only), and neither has an unlocked multiplier.

The Verdict

The data points to a clear conclusion: this is a tie in performance, but a complete mismatch in platform purpose. The Intel Core i5-1340P wins all six head-to-head benchmark tests, but the largest winning margin is 0.6%. In practical terms, the two CPUs are interchangeable in synthetic render tests. The Xeon E-2356G’s average score of 4548 is 0.1% higher than the i5’s 4545, per the nearest rival data. Neither chip has a meaningful edge in raw compute.

The decision must come down to the platform. The Xeon E-2356G is a socketed server/workstation chip with ECC memory support, a 14 nm process, and a boost clock of 5.00 GHz. It is built for reliability and upgradeability. The Core i5-1340P is a mobile chip on a BGA socket, meaning it is not user-upgradeable. It has more cores and threads, a 10 nm process, and a much lower TDP of 28 watts. It supports newer DDR5 memory and has a larger L2 cache per core.

For a builder assembling a workstation with a discrete GPU and a need for ECC, the Xeon E-2356G is the only choice between the two. For a laptop or a compact mobile system where power draw and heat are the primary constraints, the i5-1340P is the obvious pick. The benchmark scores will not help you decide, because they are effectively identical. Your motherboard and memory requirements will.

Where Each One Wins

The Intel Xeon E-2356G wins in scenarios that require a traditional socketed platform. It is the only one of the two that supports ECC memory, which is essential for data integrity in long-running compute tasks. Its higher boost clock of 5.00 GHz gives it a theoretical edge in lightly threaded workloads, though the bench results do not show a significant advantage. Its 80-watt TDP and 276 mm² die size indicate it is designed for desktop or rack systems with active cooling and a robust power delivery system. The 2021 release date and $311 launch MSRP position it as a budget server part.

The Intel Core i5-1340P wins in power-sensitive and space-constrained environments. Its 28-watt TDP makes it suitable for thin laptops and compact devices where the Xeon’s 80-watt requirement would be impossible to cool. It has more cores and threads, which helps in heavily parallel workloads, even if the benchmark deltas are tiny. The 10 nm process node and support for DDR5 memory make it the more modern part, despite its later release date of 2023. The i5 also wins on integrated graphics, with Iris Xe Graphics 80EU versus the Xeon’s UHD Graphics P750.

If you are building a stationary workstation with a socketed motherboard and ECC RAM, the Xeon E-2356G is the only sensible pick. If you are buying a laptop or a mini-PC, the Core i5-1340P is the one that exists in that form factor. The benchmark data shows you will not be giving up any measurable performance either way, so let the platform decide.
