AMD Ryzen 5 PRO 8540U vs Intel Core Ultra 9 288V Comparison

The AMD Ryzen 5 PRO 8540U and Intel Core Ultra 9 288V are both mobile processors targeting the same performance percentile, yet they achieve it through fundamentally different strengths. The data shows a clear split: Intel wins 12 of the 17 head-to-head benchmarks, while AMD takes 5, but the margin and nature of those victories tell a more nuanced story about workload suitability.

Head-to-Head Benchmarks

The most striking divergence appears in the Cinebench suite, where the two processors trade blows across different versions. In Cinebench R23 multi-core, the AMD Ryzen 5 PRO 8540U delivers a decisive 51.9% advantage over the Intel Core Ultra 9 288V, scoring 15,456 versus 10,178. This is the largest single delta in the entire comparison. Yet in Cinebench R20 multi-core, the Intel part flips the script with an 8.2% lead (7,069 vs 6,491), and in R15 multi-core, Intel edges ahead by a narrower 1.6% (1,583 vs 1,557). The R23 result is anomalous enough to warrant scrutiny—it suggests the AMD chip sustains performance better under that specific workload’s longer duration, while Intel’s advantage in the shorter R15 and R20 runs points to a burst-performance profile.

Single-core results are similarly split but with different winners. The Intel Core Ultra 9 288V dominates in Cinebench R15 single-core, posting 301.5 versus AMD’s 219, a 27.4% gap. It also leads in R20 single-core by 8.1% (997 vs 916). However, in R23 single-core, AMD counters with an 11.9% win (2,182 vs 1,950). This pattern—Intel ahead in older R15/R20, AMD ahead in R23—repeats across the suite, hinting at workload-specific scaling rather than a universal single-thread superiority for either part.

The Passmark tests reveal where each chip’s architecture shines. Intel’s floating-point math score of 59,536 crushes AMD’s 34,865, a 41.4% margin. Prime number finding is even more lopsided: Intel scores 195 versus AMD’s 66, a 66.2% deficit for AMD. Physics simulation likewise favors Intel heavily, 1,637 versus 983, a 40% gap. These are substantial, unambiguous wins for Intel’s compute-heavy capabilities.

AMD’s Passmark victories are more selective but still significant. Integer math goes to AMD by 28.9% (56,738 vs 44,019). Data compression favors AMD by 10.3% (205,703 vs 186,521), and random string sorting by 9.6% (24,797 vs 22,622). Data encryption, however, belongs to Intel by 12.9% (14,141 vs 12,319). Extended instructions are nearly a tie, with Intel ahead by just 1.3% (15,613 vs 15,410). The overall Passmark multi-thread score gives Intel an 8% edge (19,810 vs 18,218), while single-thread favors Intel by 16.6% (4,274 vs 3,563).

Where Each One Wins

The Intel Core Ultra 9 288V is the clear choice for floating-point-heavy workloads, physics simulations, and prime-number computations. Its 66.2% lead in prime finding and 41.4% lead in floating-point math are not marginal—they indicate a fundamental advantage in mathematical throughput. The 40% physics win reinforces this, making Intel the better fit for scientific computing, financial modeling, or any task relying on dense numerical operations. The 16.6% single-thread advantage also makes Intel stronger for lightly threaded applications like legacy software or latency-sensitive interactive tasks.

The AMD Ryzen 5 PRO 8540U wins where thread count and shared cache matter more than raw math throughput. Its 51.9% Cinebench R23 multi-core victory suggests exceptional sustained multi-threaded performance, likely benefiting from its 12 threads versus Intel’s 8. The 28.9% integer math lead and 10.3% data compression win point to strengths in database operations, file archiving, and general productivity where integer manipulation dominates. Random string sorting’s 9.6% edge further supports AMD’s suitability for text processing and data organization tasks.

Architecture Differences

The two processors are built on different philosophies. AMD uses Zen 4 architecture on a 4nm TSMC process, with 6 cores and 12 threads. Intel’s Lunar Lake architecture is on a smaller 3nm TSMC node, but employs 8 cores with only 8 threads—no simultaneous multithreading. This thread disparity is critical: AMD can process 12 threads concurrently, while Intel is limited to 8, yet Intel compensates with higher base and boost clocks (3.30 GHz base, 5.10 GHz boost versus AMD’s 3.20 GHz and 4.90 GHz).

Cache configurations differ substantially. AMD allocates 64 KB L1 and 1 MB L2 per core, with 16 MB shared L3. Intel gives each core 192 KB L1 and 2.5 MB L2, but only 12 MB shared L3. Intel’s larger per-core L1 and L2 caches likely explain its single-thread and floating-point wins, while AMD’s larger L3 pool supports its multi-threaded integer performance. Memory bandwidth also favors Intel: 136.5 GB/s versus AMD’s 89.6 GB/s, with Intel using LPDDR5X and AMD DDR5. Both run dual-channel, but Intel’s higher bandwidth is evident in its encryption and physics results.

PCIe connectivity is another divider. AMD offers Gen 4 with 14 CPU lanes, while Intel provides Gen 5 with only 4 lanes. The integrated GPUs also differ—AMD has Radeon 740M, Intel has Arc 140V—though neither is benchmarked here. AMD supports ECC memory; Intel does not. Power envelopes are close, with AMD at 28W TDP and Intel at 30W TDP, but the 3nm node gives Intel a density advantage despite the larger core count.

The Verdict

Benchmark results indicate that the Intel Core Ultra 9 288V is the stronger all-around processor for compute-intensive and single-threaded tasks. Its 12 wins out of 17 benchmarks, including dominant margins in floating-point math, prime finding, physics, and single-thread performance, make it the default recommendation for users prioritizing numerical analysis, simulation, or responsive single-threaded applications. The 8% Passmark multi-thread lead and 16.6% single-thread lead reinforce this, even though AMD wins the flagship Cinebench R23 multi-core test.

The AMD Ryzen 5 PRO 8540U is not a runner-up—it is the specialist. For workloads that scale with thread count and benefit from larger shared cache, AMD’s 51.9% Cinebench R23 multi-core win and 28.9% integer math advantage are compelling. Data compression and string sorting wins suggest real-world productivity gains in file handling and data processing. The 12-thread capability is a structural advantage Intel cannot match, making AMD the pick for heavily parallel integer workloads, especially where sustained multi-core performance is the bottleneck.

Choosing between them depends on whether the priority is raw mathematical throughput or multi-threaded integer scaling. Intel wins the broad benchmark count; AMD wins the most dramatic single benchmark and the workloads where threads outrank clock speed.
