AMD Ryzen Embedded V2748 vs Intel Xeon W-2140B Comparison

The Verdict

The recorded data paints a clear picture: the AMD Ryzen Embedded V2748 wins every single head-to-head benchmark in the database against the Intel Xeon W-2140B. Across six Cinebench tests, the AMD part leads by margins ranging from 5.9% to 6.3%. The most significant single-core advantage appears in Cinebench R15, where the V2748 scores 222 versus 209, a 5.9% lead. Multi-core results are similarly consistent, with the V2748 posting 1579 in Cinebench R15 multicore against 1480 for the Intel chip, a 6.3% gap.

The Intel Xeon W-2140B does not win any benchmark in the comparison. Its average benchmark score sits at 4272, while the AMD Ryzen Embedded V2748 averages 4532. Both processors land at the 58th percentile among all CPUs in the database, meaning they occupy the same overall performance tier despite the AMD part's consistent edge in every recorded test.

Who should pick which? The data suggests the AMD Ryzen Embedded V2748 is the straightforward choice for workloads that rely on Cinebench-style rendering performance, as it holds a uniform advantage in both single-threaded and multi-threaded tasks. The Intel Xeon W-2140B, however, remains relevant in systems built around its platform characteristics rather than raw benchmark scores. It offers a larger 11 MB shared L3 cache, a quad-channel memory bus with 85.3 GB/s of bandwidth, and 48 PCIe Gen 3 lanes from the CPU. These platform-level attributes are not captured in Cinebench scores but matter for memory-intensive or I/O-heavy server and workstation configurations.

The V2748, by contrast, is an active, current product with a 35 W TDP and integrated Radeon Graphics with 448 shader processors. The Xeon W-2140B is end-of-life, carries a 120 W TDP, and has no integrated graphics. For a new system where benchmark performance per watt is the priority, the Ryzen Embedded part is the data-backed choice. For a workstation that needs maximum memory bandwidth, a large L3 cache, and abundant PCIe lanes, the Xeon W-2140B has platform advantages that the benchmark scores do not reflect.

FAQ

Q: Which processor has the higher average benchmark score?

A: The AMD Ryzen Embedded V2748 averages 4532, while the Intel Xeon W-2140B averages 4272. The AMD part leads by roughly 260 points, a margin that aligns with its consistent 6% advantage across Cinebench tests.

Q: How large is the performance gap in multi-core workloads?

A: The AMD Ryzen Embedded V2748 leads by 6.2% in Cinebench R20 and R23 multicore tests, and by 6.3% in Cinebench R15 multicore. The scores are 6580 versus 6170 in R20, 15668 versus 14692 in R23, and 1579 versus 1480 in R15.

Q: Does the Intel Xeon W-2140B win any benchmark?

A: No. The database records zero wins for the Intel part. The AMD Ryzen Embedded V2748 wins all six head-to-head tests, covering three Cinebench versions in both single-core and multicore runs.

Q: What platform features differentiate the two processors?

A: The Intel Xeon W-2140B supports quad-channel DDR4 memory with 85.3 GB/s bandwidth and offers 48 PCIe Gen 3 lanes from the CPU. The AMD Ryzen Embedded V2748 uses dual-channel DDR4 with 51.2 GB/s bandwidth and provides 20 PCIe Gen 3 lanes. Both support ECC memory.

Q: Which processor is more power-efficient according to the data?

A: The AMD Ryzen Embedded V2748 has a 35 W TDP, while the Intel Xeon W-2140B has a 120 W TDP. The AMD part achieves higher benchmark scores while drawing less than a third of the thermal design power, making it the clear efficiency leader in this comparison.

Q: Are the processors manufactured on different process nodes?

A: Yes. The Intel Xeon W-2140B uses Intel's 14 nm process in the Skylake-W architecture. The AMD Ryzen Embedded V2748 uses TSMC's 7 nm process in the Zen 2 Renoir architecture.

Architecture Differences

The two processors come from fundamentally different design generations. The Intel Xeon W-2140B uses the Skylake-W architecture, built on Intel's 14 nm process node. It is a server and workstation part with a die size of 484 mm². The AMD Ryzen Embedded V2748 belongs to the Zen 2 architecture under the Renoir codename, fabricated by TSMC on a 7 nm process, with a die size of 156 mm² and 9,800 million transistors. The process and design gap is substantial, which helps explain why the AMD part delivers higher performance while operating at a much lower TDP.

Cache hierarchies differ as well. Both processors have 64 KB of L1 cache per core. The Intel part has 1 MB of L2 cache per core and 11 MB of shared L3 cache. The AMD part has 512 KB of L2 cache per core and 8 MB of shared L3 cache. The Intel design provides more L2 and L3 cache per core, which can benefit workloads with high cache locality. The AMD design compensates with a more efficient core architecture and higher boost clock.

Memory architecture also diverges. The Xeon W-2140B uses a quad-channel DDR4 memory bus with 85.3 GB/s of bandwidth, while the V2748 uses dual-channel DDR4 with 51.2 GB/s. Both support ECC memory, which is expected for processors targeting server and workstation roles. The Intel part provides 48 PCIe Gen 3 lanes from the CPU, far more than the 20 lanes offered by the AMD part. This makes the Xeon more suitable for systems with many expansion cards, such as multiple GPUs, NVMe storage adapters, or high-speed networking.

The AMD Ryzen Embedded V2748 includes integrated Radeon Graphics with 448 shader processors, a feature entirely absent from the Intel Xeon W-2140B. For systems that need a display output without a discrete GPU, this is a meaningful architectural advantage.

Specification Differences

The core and thread counts are identical: both processors have 8 cores and 16 threads. The similarities end there.

Clock speeds differ slightly. The Intel Xeon W-2140B has a base clock of 3.20 GHz and a boost clock of 4.20 GHz. The AMD Ryzen Embedded V2748 has a base clock of 2.90 GHz and a boost clock of 4.25 GHz. Despite the lower base clock, the AMD part reaches a higher boost frequency and wins every benchmark in the database.

TDP is a major differentiator. The Intel part draws 120 W, while the AMD part draws only 35 W. That is a 85 W difference in thermal design power, which has direct implications for cooling requirements and system density.

Sockets are incompatible. The Intel Xeon W-2140B uses Intel Socket 2066, while the AMD Ryzen Embedded V2748 uses AMD Socket FP6. The Intel part is end-of-life, released in December 2017. The AMD part is active, released in November 2020.

Memory support differs in channel count and bandwidth, as noted: quad-channel 85.3 GB/s for Intel versus dual-channel 51.2 GB/s for AMD. PCIe lane count also differs, 48 lanes versus 20 lanes. The Intel part has no integrated graphics; the AMD part includes Radeon Graphics with 448 shader processors.

Neither processor has an unlocked multiplier, and both are listed without a launch MSRP in the database.

Head-to-Head Benchmarks

The AMD Ryzen Embedded V2748 sweeps all six recorded Cinebench comparisons. The margins are remarkably consistent, hovering around 6% in every test.

In Cinebench R15 multicore, the V2748 scores 1579 against 1480 for the Xeon W-2140B, a 6.3% advantage. The single-core R15 result is closer: 222 versus 209, a 5.9% lead. These are the largest and smallest margins in the entire comparison, respectively.

Cinebench R20 follows the same pattern. The AMD part scores 6580 in multicore versus 6170 for the Intel part, a 6.2% lead. In single-core, the V2748 posts 929 versus 871, again a 6.2% margin.

Cinebench R23 multicore shows the AMD part reaching 15668 against 14692 for the Intel part, a 6.2% difference. The single-core R23 result is 2212 versus 2074, also a 6.2% gap. The consistency of these deltas suggests a stable architectural advantage rather than a workload-specific quirk.

The Intel Xeon W-2140B has additional Geekbench scores in the database: 7381 multicore and 1299 single-core. The AMD Ryzen Embedded V2748 does not have Geekbench results recorded, so no direct comparison is possible for that test suite.

The nearest rivals in the database provide context for each processor's standing. The Xeon W-2140B sits within 1% of the Intel Xeon E5-4669 v3, AMD Ryzen 7 PRO 5750G, Intel Core i7-1265U, and Intel Xeon E-2378. The AMD V2748 sits within 0.4% of the Intel Core i5-1340P, Intel Core i7-10700KF, Intel Xeon E-2356G, and Intel Core i5-1250P. Both processors occupy similar competitive territory, but the AMD part does so with a substantial efficiency advantage.

The data indicates that in pure compute performance, the AMD Ryzen Embedded V2748 is the stronger part in this matchup. The Intel Xeon W-2140B retains platform advantages in memory bandwidth, cache capacity, and PCIe expansion, which remain relevant for specific workstation and server configurations.
