AMD Ryzen 7 7840U vs Intel Xeon D-2752TER Comparison

The Verdict

The data presents a clear split between two very different processors. The Intel Xeon D-2752TER and AMD Ryzen 7 7840U occupy distinct market segments, and benchmark results reflect that positioning. The AMD Ryzen 7 7840U wins 11 of the 15 head-to-head comparisons, while the Intel Xeon D-2752TER takes 4. However, the nature of those wins matters more than the count.

The Intel Xeon D-2752TER is the choice for workloads that depend on sustained multi-core throughput and physics-style calculations. It leads in Cinebench R23 multi-core by 27.5% and in PassMark physics by 41.5%. Its 12 cores and 24 threads, combined with 20 MB of shared L3 cache, give it an edge in rendering and simulation tasks that scale with core count. The AMD Ryzen 7 7840U, despite having only 8 cores and 16 threads, dominates in single-threaded performance, integer math, floating-point math, and data encryption. The PassMark single-thread score tells the story: 3565 for the AMD versus 1990 for the Intel, a 44.2% gap.

For mobile users, the Ryzen 7 7840U is the obvious pick. It is a Mobile segment part with a 28 W TDP, versus the Xeon's 77 W TDP and Server/Workstation segment. The Ryzen's 4 nm process from TSMC, versus Intel's 10 nm node, explains much of its efficiency advantage. For server and workstation deployments where sustained multi-core rendering or physics simulation is the priority, the Xeon D-2752TER's higher core count and larger L3 cache make it the better fit. The data also shows the Xeon has a higher percentile ranking at 78 versus the Ryzen's 77, though the average benchmark scores are nearly identical: 25530 for Intel and 25432 for AMD. That near-tie in overall average, combined with the divergent workload-specific results, means the decision hinges entirely on the application profile.

Architecture Differences

The architectural gap between these two chips is wide. The Intel Xeon D-2752TER is built on Ice Lake-D architecture, manufactured on Intel's 10 nm process. The AMD Ryzen 7 7840U uses Zen 4 architecture, branded as Phoenix, on TSMC's 4 nm node. That process difference—10 nm versus 4 nm—is the single largest factor explaining the performance-per-watt gap. The AMD chip packs 25,000 million transistors into a 178 mm² die, while the Intel die size is not listed in the data.

Cache hierarchies differ significantly. The Intel uses 80 KB of L1 per core, 1.25 MB of L2 per core, and 20 MB of shared L3. The AMD uses 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3. The Intel's larger per-core caches and bigger L3 pool serve its 12-core design, while the AMD's smaller cache footprint reflects its mobile-first 8-core design.

Memory architecture diverges as well. The Intel supports DDR4 with a quad-channel memory bus, achieving 85.3 GB/s bandwidth. The AMD supports DDR5 with a dual-channel bus, achieving 89.6 GB/s—slightly higher bandwidth despite fewer channels. PCIe support also differs: the Intel provides Gen 4 with 32 lanes (CPU only), while the AMD provides Gen 4 with 20 lanes (CPU only). The AMD includes integrated Radeon 780M graphics; the Intel has no integrated graphics listed.

The socket and packaging are entirely different. The Intel uses Intel BGA 2579, while the AMD uses AMD Socket FP8. The Intel part number is listed as SRLCNSRM27, while the AMD has multiple part numbers: 100-000000829100-000000830100-000001131. Neither processor has an unlocked multiplier.

Specification Differences

The two processors differ across nearly every major specification category. Core and thread counts are the most obvious: the Intel offers 12 cores and 24 threads versus the AMD's 8 cores and 16 threads. Clock speeds tell a different story. The Intel has a base clock of 1800.00 MHz and a boost clock of 2.80 GHz, while the AMD has a base clock of 3.30 GHz and a boost clock of 5.10 GHz. The AMD's 2.3 GHz boost advantage explains its single-thread dominance.

TDP is a critical differentiator: 77 W for the Intel versus 28 W for the AMD. This is a 49 W gap, making the AMD far more suitable for thin-and-light mobile devices. The market segments reflect this: Intel targets Server/Workstation, AMD targets Mobile. The Intel was released on 2022-02-23 and has a launch MSRP of $1061; the AMD has no release date or MSRP listed in the data.

Memory support is generationally split: DDR4 for Intel, DDR5 for AMD. The memory bus is quad-channel for Intel and dual-channel for AMD, yet bandwidth is nearly identical at 85.3 GB/s versus 89.6 GB/s. Both support ECC memory. The process node is 10 nm (Intel, Intel foundry) versus 4 nm (AMD, TSMC foundry). The AMD's transistor count of 25,000 million and die size of 178 mm² are listed; corresponding Intel figures are absent from the data.

Head-to-Head Benchmarks

The 15 head-to-head benchmarks reveal a pattern of AMD dominance in most compute tasks, with Intel winning in specific multi-core and physics scenarios. Starting with the AMD wins: PassMark single-thread shows the largest gap, 3565 versus 1990, a 44.2% advantage. Floating-point math follows with 51767 versus 33533, a 35.2% margin. Integer math shows 90852 versus 60881, a 33% lead. Extended instructions are 20432 versus 13846, a 32.2% gap. Data encryption is 17691 versus 13097, a 26% win. PassMark multithread shows 24782 versus 19102, a 22.9% edge. Data compression is 288604 versus 227763, a 21.1% margin. Cinebench R15 multi-core goes to AMD with 1990 versus 1634, a 17.9% lead. Cinebench R15 single-core also goes to AMD with 264 versus 230, a 12.9% margin. Random string sorting is close, with AMD winning 33757 versus 31802, a 5.8% edge.

The Intel wins are fewer but decisive in specific areas. Cinebench R23 single-core: 2288 versus 1677.5, a 36.4% lead. Cinebench R23 multi-core: 16212 versus 12719, a 27.5% win. Find prime numbers: 96 versus 80, a 20% advantage. Physics: 1777 versus 1256, a 41.5% blowout. The physics result is the Intel's largest margin, and it aligns with the Xeon's server-oriented design.

The Cinebench results deserve special attention. The AMD wins R15 multi-core and single-core, but the Intel wins R23 in both categories. The R23 multi-core gap of 27.5% is substantial, suggesting that the Intel's 12-core design scales better in the newer test. The R23 single-core win for Intel is surprising given the AMD's clock advantage, but the data is unambiguous: 2288 versus 1677.5.

Where Each One Wins

The AMD Ryzen 7 7840U wins in most everyday compute tasks and any workload that benefits from high clock speeds. Its 5.10 GHz boost clock drives wins in single-threaded tests, integer math, floating-point math, and extended instructions. Data compression and encryption also favor the AMD, with 21.1% and 26% margins respectively. For mobile users running general productivity, development, or content creation on the go, the AMD's combination of 8 cores, high clocks, and 28 W TDP makes it the clear choice. The integrated Radeon 780M graphics add capability that the Intel lacks entirely, though no GPU benchmarks are provided in the data. The AMD's higher memory bandwidth (89.6 GB/s versus 85.3 GB/s) and DDR5 support further favor it for memory-intensive mobile tasks.

The Intel Xeon D-2752TER wins in server and workstation scenarios where sustained multi-core rendering and physics simulation are critical. Its Cinebench R23 multi-core score of 16212 versus 12719 is a 27.5% advantage that matters for 3D rendering, video encoding, and scientific computing. The physics benchmark win of 41.5% suggests strong performance in simulation workloads. The find prime numbers result, a 20% edge, indicates competent integer-heavy server tasks. With 12 cores, 24 threads, 20 MB of L3 cache, and quad-channel DDR4 memory, the Intel is built for throughput. Its 77 W TDP is high for mobile, but that is irrelevant in a server chassis. The launch MSRP of $1061 positions it as a professional-grade part, though pricing discussion is limited to that single figure.

The overall average benchmark scores are nearly tied—25530 for Intel versus 25432 for AMD—and their percentile rankings are close (78 versus 77). The nearest rivals for each confirm this middle-tier positioning: the Intel's closest competitor is the AMD Ryzen 7 5700 (0.1% delta), while the AMD's closest rival is the Intel Core i7-11700KF (0% delta). The data does not declare an overall winner; it declares two different tools for two different jobs. Choose the Intel for rack-mounted multi-core workloads. Choose the AMD for portable, high-clock, power-efficient computing.
