AMD Ryzen 5 8640HS vs Intel Xeon D-2752TER Comparison

Where Each One Wins

The AMD Ryzen 5 8640HS and Intel Xeon D-2752TER are aimed at fundamentally different workloads, and the benchmark data reflects that split clearly. The Ryzen 5 8640HS wins 9 of the 15 recorded head-to-head comparisons, while the Xeon D-2752TER takes 6. The wins are not scattered randomly; they cluster around specific task types.

The Ryzen 5 8640HS dominates single-threaded and lightly threaded work. Its most dramatic victory is in PassMark single-thread performance, where it scores 3584 against the Xeon's 1990, an 80.1% advantage. That is not a small gap; it is a generational difference in how each chip handles a single task. The Ryzen also wins Cinebench R15 single-core by 16.5% (268 vs 230) and leads in floating-point math by 18.5% (39725 vs 33533). Integer math goes to the Ryzen by 12% (68173 vs 60881). Extended instruction workloads also favor the Ryzen by 14.5% (15855 vs 13846). Data encryption is closer but still favors the Ryzen at 3.5% (13551 vs 13097).

The Xeon D-2752TER wins where thread count and sustained throughput matter more than clock speed. Its biggest victory is in Cinebench R23 multi-core, scoring 16212 against the Ryzen's 11486, a 29.2% margin. It also wins Cinebench R23 single-core by 25.2% (2288 vs 1711), which is notable given the Ryzen's single-thread advantage in other tests. The Xeon takes PassMark physics by a massive 45.4% (1777 vs 970), and it leads in prime number finding by 27.1% (96 vs 70). Random string sorting goes to the Xeon by 14.1% (31802 vs 27316), and data compression is essentially a tie, with the Xeon ahead by just 0.5% (227763 vs 226544).

What this means in practice: the Ryzen 5 8640HS is the better choice for interactive, latency-sensitive, or single-thread-bound applications. The Xeon D-2752TER is the better choice for heavily parallel workloads that can use all 12 cores and 24 threads, particularly those that involve physics simulation, prime number computation, or sorting large datasets.

Architecture Differences

The two processors come from different design philosophies. The Ryzen 5 8640HS is a mobile part built on TSMC's 4 nm process, part of the Zen 4 (Hawk Point) architecture. The Xeon D-2752TER is a server/workstation part built on Intel's 10 nm process, using the Ice Lake-D architecture. The process node difference alone explains much of the clock speed gap: the Ryzen runs at 3.50 GHz base and 4.90 GHz boost, while the Xeon runs at 1800 MHz base (1.80 GHz) and 2.80 GHz boost. Lower clocks on the Xeon are offset by having twice the cores.

Core counts differ sharply. The Ryzen has 6 cores and 12 threads; the Xeon has 12 cores and 24 threads. Cache layouts also differ. The Ryzen uses 64 KB L1 per core, 1 MB L2 per core, and 16 MB shared L3. The Xeon uses 80 KB L1 per core, 1.25 MB L2 per core, and 20 MB shared L3. The Xeon's larger per-core L1 and L2 caches, combined with more cores, help in multi-threaded scenarios.

Memory support is a major differentiator. The Ryzen uses DDR5 on a dual-channel bus with 89.6 GB/s bandwidth and no ECC support. The Xeon uses DDR4 on a quad-channel bus with 85.3 GB/s bandwidth and supports ECC memory. The Ryzen has slightly higher peak memory bandwidth despite fewer channels, but the Xeon's ECC support makes it suitable for reliability-critical server roles. PCIe lanes also differ: the Ryzen offers Gen 4 with 20 lanes, while the Xeon offers Gen 4 with 32 lanes.

The Ryzen includes integrated Radeon 760M graphics; the Xeon has no integrated graphics. The Ryzen is a mobile part on AMD Socket FP8, while the Xeon is a server part on Intel BGA 2579. The Ryzen's TDP is 28 watts, the Xeon's is 77 watts. The Ryzen was released in December 2023; the Xeon was released in February 2022. The Xeon has a launch MSRP of $1061.

Head-to-Head Benchmarks

The single-thread results tell two different stories depending on the benchmark. In PassMark single-thread, the Ryzen 5 8640HS scores 3584 versus the Xeon's 1990, an 80.1% lead. That is the largest delta in the entire comparison. In Cinebench R15 single-core, the Ryzen leads by 16.5% (268 vs 230). However, in Cinebench R23 single-core, the Xeon reverses the trend, scoring 2288 against the Ryzen's 1711, a 25.2% margin. This discrepancy likely reflects different workload characteristics between Cinebench versions and PassMark's test suite.

Multi-core results are similarly split. The Ryzen wins Cinebench R15 multi-core by 12.9% (1845 vs 1634), but the Xeon wins Cinebench R23 multi-core by 29.2% (16212 vs 11486). The R23 test is more demanding and scales better with core count, which explains the Xeon's advantage. In PassMark multithread, the Ryzen wins by 4.1% (19889 vs 19102), a narrow margin that suggests the Ryzen's higher clocks compensate for fewer cores in this particular workload.

The physics test is the Xeon's strongest showing. It scores 1777 versus the Ryzen's 970, a 45.4% advantage. Physics workloads often scale with core count and raw FPU throughput, both of which favor the 12-core Xeon. Prime number finding also goes to the Xeon by 27.1% (96 vs 70). Random string sorting favors the Xeon by 14.1% (31802 vs 27316), likely due to its larger caches and more threads.

The Ryzen's wins in extended instructions (14.5%), floating-point math (18.5%), and integer math (12%) show that its Zen 4 cores are more efficient per clock. Data encryption is close, with the Ryzen ahead by 3.5% (13551 vs 13097). Data compression is effectively a tie at 0.5% (226544 vs 227763), with the Xeon barely ahead.

The Verdict

The data points to two different buyer profiles. The Ryzen 5 8640HS is for someone who needs strong single-threaded responsiveness, efficient floating-point and integer math, and integrated graphics in a low-power mobile package. Its 80.1% single-thread lead over the Xeon, combined with wins in extended instructions and encryption, makes it the practical choice for desktop-style applications, development work, and general productivity on the go.

The Xeon D-2752TER is for server and workstation deployments where ECC memory, 32 PCIe lanes, and 12 cores matter more than raw clock speed. Its 29.2% lead in Cinebench R23 multi-core and 45.4% lead in physics show that it handles sustained parallel loads better. The Xeon's 77-watt TDP and server socket reflect its intended role in always-on systems.

The Ryzen's 9 wins versus the Xeon's 6 wins in head-to-head benchmarks might suggest an overall victory, but that is misleading. The benchmark suite includes many single-threaded and light-thread tests where the Ryzen's high clocks dominate. In the heavy multi-threaded tests that matter for server workloads, the Xeon consistently pulls ahead. The Ryzen 5 8640HS is the better all-around mobile processor; the Xeon D-2752TER is the better dedicated compute engine for parallel tasks. Choose based on workload, not on total win count.
