CPU Comparison

The Intel Xeon E-2276M and AMD Ryzen Embedded V1756B are both 45 W processors aimed at compact, always-on systems, yet their benchmark results tell a surprisingly one-sided story. Despite the Xeon’s higher boost clock and larger L3 cache, the data shows the AMD part winning every single head-to-head test, often by a margin of roughly 21%. This outcome challenges the assumption that a newer, higher-clocked server chip would automatically dominate an older embedded part, and the specification sheets reveal why.

Head-to-Head Benchmarks

The benchmark results are unambiguous: the AMD Ryzen Embedded V1756B wins all six recorded comparisons, with the Intel Xeon E-2276M trailing by a consistent margin. In Cinebench R15 multi-core, the AMD scores 692 against the Intel’s 544, a delta of -21.4% for the Xeon. The single-core R15 test shows a similar gap: AMD’s 97 versus Intel’s 76, a -21.6% difference. This pattern repeats across every Cinebench version, from R15 through R23, with deltas hovering between -21.2% and -21.6%. For instance, in Cinebench R20 multi-core, the AMD part hits 2884 while the Intel manages only 2268, and in R23 multi-core, the scores are 6867 versus 5400. The consistency of the ~21% deficit suggests a fundamental architectural advantage for AMD in this workload, not just a clock-speed quirk.

Single-core performance is particularly telling. The Intel Xeon E-2276M has a boost clock of 4.70 GHz, far higher than the AMD’s 3.60 GHz, yet it still loses Cinebench R23 single-core by 21.4% (762 versus 969). This indicates that the AMD’s Zen architecture delivers more instructions per clock, offsetting its lower frequency. The Geekbench results, while only available for the Intel, reinforce its mid-range standing: a multi-core score of 5159 and single-core of 1440, placing it in the 44th percentile of all CPUs. The AMD’s percentile is also 44, but its average benchmark score of 1986 is only slightly below the Intel’s 1996, a difference of just 0.5%.

The nearest rivals for each chip further contextualize the gap. The Intel Xeon E-2276M sits within 0.3% of the Intel Core i7-7920HQ and AMD Ryzen 5 1500X (both scoring 1992), and is 0.3% ahead of the Xeon E3-1285L v4. The AMD V1756B, meanwhile, is essentially tied with the Intel Core i5-8279U (delta 0%) and trails the Xeon E3-1585L v5 by 0.2%. This means that despite the AMD’s clean sweep in head-to-head tests, both chips occupy the same performance tier relative to the broader market, making the Xeon’s losses more about architectural efficiency than raw capability.

FAQ

Q: Why does the AMD Ryzen Embedded V1756B win every Cinebench test despite having fewer cores?

A: The AMD has 4 cores and 8 threads versus the Intel’s 6 cores and 12 threads, yet it wins by ~21% across R15, R20, and R23. The data suggests the Zen architecture’s per-core efficiency is superior, as its 3.60 GHz boost clock is far lower than the Intel’s 4.70 GHz, yet single-core scores are still 21.4% higher.

Q: Is the Intel Xeon E-2276M’s higher boost clock useless?

A: Not entirely, but it does not translate into benchmark wins. The Intel boosts to 4.70 GHz while the AMD peaks at 3.60 GHz, yet the AMD’s Cinebench R23 single-core score is 969 versus 762. This implies the AMD executes more work per clock cycle, making raw frequency a poor predictor of performance here.

Q: How do these chips compare to their closest rivals?

A: Both are statistically tied with similar mid-range parts. The Intel Xeon E-2276M is within 0.3% of the Core i7-7920HQ and Ryzen 5 1500X, while the AMD V1756B is within 0.2% of the Xeon E3-1585L v5 and exactly tied with the Core i5-8279U.

Q: Do both chips have the same average benchmark score?

A: Not exactly. The Intel averages 1996 across all benchmarks, while the AMD averages 1986, a 0.5% difference. Despite this, the AMD wins every head-to-head test, meaning its scores are more consistent across the specific Cinebench workloads.

Q: Which chip has better memory support?

A: Both support DDR4 dual-channel memory, but the Intel lists a memory bandwidth of 42.7 GB/s and supports ECC memory. The AMD does not list a bandwidth figure and does not support ECC, which may matter for error-sensitive workloads.

Q: Are these chips still in production?

A: No. The Intel Xeon E-2276M is marked as end-of-life, while the AMD Ryzen Embedded V1756B is still listed as active production. This could affect long-term availability for new designs.

Architecture Differences

The two processors come from different architectural lineages, which explains their divergent performance profiles. The Intel Xeon E-2276M uses the Coffee Lake-H architecture, built on a 14 nm process by Intel, with a die size of 154 mm². It packs 6 cores and 12 threads, with 64 KB of L1 and 256 KB of L2 per core, plus a shared 12 MB L3 cache. The AMD Ryzen Embedded V1756B, in contrast, uses the original Zen architecture (codename “Great Horned Owl”), also on 14 nm but manufactured by GlobalFoundries, with a larger 210 mm² die containing 4,950 million transistors. It has 4 cores and 8 threads, with larger 128 KB L1 and 512 KB L2 per core, but only 2 MB of shared L3 cache.

The cache disparity is striking: the Intel has six times more L3 (12 MB versus 2 MB), yet still loses in memory-intensive Cinebench workloads. This suggests the AMD’s larger per-core L1 and L2 caches (double the Intel’s) are more effective for the test’s working set. The AMD also has a higher base clock (3.25 GHz versus 2.80 GHz) but a much lower boost clock (3.60 GHz versus 4.70 GHz), indicating it relies on sustained efficiency rather than short bursts. Both chips have integrated graphics, with the Intel featuring UHD Graphics P630 and the AMD sporting Radeon Vega 8, though the benchmark data does not cover GPU performance.

Another key divergence is memory and expansion. The Intel supports ECC memory with a documented bandwidth of 42.7 GB/s and offers PCIe Gen 3 with 16 lanes from the CPU. The AMD does not list ECC support, memory bandwidth, or PCIe lanes in the data, leaving those features unspecified. The Intel is a server/workstation part on an Intel BGA 1440 socket, while the AMD is a desktop-class embedded chip on AMD Socket FP5. The Intel was released in 2019 with a launch MSRP of $450, whereas the AMD launched in 2018 with no listed MSRP. These architectural choices reflect different design priorities: the Intel emphasizes multi-core throughput and enterprise features, while the AMD focuses on per-core efficiency and compact integration.

The Verdict

Based strictly on benchmark data, the AMD Ryzen Embedded V1756B is the clear winner for compute-intensive tasks. It outperforms the Intel Xeon E-2276M by roughly 21% in every Cinebench test, from R15 to R23, in both single-core and multi-core workloads. The AMD achieves this with fewer cores and threads, a lower boost clock, and a fraction of the L3 cache, which points to a superior architectural design for these specific workloads. The Intel’s only advantages are its support for ECC memory, higher memory bandwidth (42.7 GB/s), and a larger 12 MB L3 cache, but these do not manifest as performance wins in the available benchmarks.

For users prioritizing raw compute in Cinebench-style applications, the AMD is the data-backed choice. Its average benchmark score of 1986 is nearly identical to the Intel’s 1996, but its consistent head-to-head dominance means it will deliver better results in these tests. The Intel’s end-of-life status and higher launch MSRP ($450) further weaken its case, though the AMD’s lack of ECC support may disqualify it for certain server or workstation roles. The verdict is clear: the AMD wins on performance, while the Intel retains value only for specific enterprise feature requirements.

Specification Differences

The two chips differ in nearly every core specification. The Intel Xeon E-2276M has 6 cores and 12 threads, while the AMD Ryzen Embedded V1756B has 4 cores and 8 threads. The Intel’s base clock is 2.80 GHz versus the AMD’s 3.25 GHz, but the Intel’s boost clock of 4.70 GHz far exceeds the AMD’s 3.60 GHz. Both are 45 W TDP parts, but the Intel uses an Intel BGA 1440 socket while the AMD uses AMD Socket FP5. The Intel’s cache layout is 64 KB L1 and 256 KB L2 per core with 12 MB shared L3; the AMD has 128 KB L1 and 512 KB L2 per core with only 2 MB shared L3. The Intel’s die is 154 mm², while the AMD’s is 210 mm², and the AMD lists 4,950 million transistors versus no transistor count for the Intel.

Memory support differs as well. Both use DDR4 dual-channel, but the Intel documents 42.7 GB/s bandwidth and ECC support, while the AMD lists neither. The Intel has PCIe Gen 3 with 16 lanes, while the AMD provides no PCIe data. Integrated graphics also differ: Intel UHD Graphics P630 versus AMD Radeon Vega 8. The Intel is a server/workstation part, launched in 2019 with a $450 MSRP and now end-of-life; the AMD is a desktop embedded part, launched in 2018, still active, with no MSRP listed. Process nodes are identical at 14 nm, but the foundry differs (Intel versus GlobalFoundries).

Where Each One Wins

The AMD Ryzen Embedded V1756B wins every head-to-head benchmark, making it the superior choice for raw compute performance. It wins Cinebench R15 multi-core (692 versus 544) and single-core (97 versus 76), R20 multi-core (2884 versus 2268) and single-core (406 versus 320), and R23 multi-core (6867 versus 5400) and single-core (969 versus 762). This makes it the pick for workloads that rely on sustained CPU throughput, such as rendering, encoding, or general parallel processing, where its ~21% lead is consistent and repeatable.

The Intel Xeon E-2276M, despite losing all benchmarks, retains specific advantages that the data supports. It supports ECC memory, which the AMD does not, making it the only option for error-correcting code applications. It also has a documented memory bandwidth of 42.7 GB/s, while the AMD lists none, and its 12 MB L3 cache is six times larger than the AMD’s 2 MB, which could benefit workloads with large working sets not captured by Cinebench. The Intel’s higher boost clock (4.70 GHz) may also offer burst performance in scenarios that favor short, high-frequency tasks, though the benchmark data does not show this. For users needing ECC, higher memory bandwidth, or a server-grade feature set, the Intel is the only viable choice; for everyone else, the AMD’s benchmark dominance is decisive.
