AMD Ryzen 5 PRO 8540U vs Intel Core 7 251TE Comparison

The Verdict

The recorded benchmark data shows a decisive performance gap between these two processors. The Intel Core 7 251TE wins all 17 head-to-head benchmark comparisons, with the AMD Ryzen 5 PRO 8540U registering zero wins. The Intel part delivers substantially higher scores across every single test category, from single-threaded workloads to heavily multithreaded render tasks.

The Intel Core 7 251TE holds an 88th percentile ranking among all CPUs in the database, while the AMD Ryzen 5 PRO 8540U sits at the 76th percentile. The average benchmark score for the Intel processor is 41650, compared to 23709 for the AMD part. That represents a performance class separation, not a marginal difference. The Intel Core 7 251TE finds its nearest rivals among high-end mobile and desktop parts such as the Intel Core Ultra 7 265H and the Intel Core i7-14650HX, both within 0.2 percent of its average score. The AMD Ryzen 5 PRO 8540U, by contrast, competes with the Intel Core i5-11500 and the AMD Ryzen 7 8840U, with deltas of 0 percent and -1.1 percent respectively.

For buyers focused purely on compute throughput, the Intel Core 7 251TE is the clear choice. The data shows it delivers roughly 65 percent higher average benchmark scores than the AMD part. However, the two processors serve different market segments. The AMD Ryzen 5 PRO 8540U is a mobile processor with a 28 watt TDP, while the Intel Core 7 251TE is a desktop part rated at 45 watts. The AMD chip uses the newer 4 nm process node from TSMC, while Intel uses its own 10 nm node. These differences matter for system design and thermal constraints, even if the raw performance data strongly favors Intel.

Architecture Differences

The two processors come from different design philosophies and manufacturing approaches. The AMD Ryzen 5 PRO 8540U uses the Zen 4 architecture with the Hawk Point codename, fabricated on TSMC's 4 nm process node. The die size measures 137 mm² and contains 20,900 million transistors. The Intel Core 7 251TE uses the Bartlett Lake codename, fabricated on Intel's 10 nm process node with a die size of 215 mm². The database does not list a transistor count for the Intel part.

The core configurations differ dramatically. AMD provides 6 cores and 12 threads, while Intel provides 24 cores and 32 threads. The cache hierarchy also differs.

The larger L3 allocation on the Intel part likely contributes to its advantage in cache-sensitive workloads.

Both processors integrate graphics. The AMD Ryzen 5 PRO 8540U includes the Radeon 740M, while the Intel Core 7 251TE includes UHD Graphics 770. The database does not provide comparative graphics benchmark scores, so the analysis here focuses on CPU compute.

The memory controllers differ in supported memory types. AMD supports DDR5 only, while Intel supports both DDR4 and DDR5. Both use dual-channel memory buses with identical peak bandwidth figures of 89.6 GB/s. The PCIe interfaces also differ: AMD provides Gen 4 with 14 lanes (CPU only), while Intel provides Gen 5 with 16 lanes (CPU only).

The market segments differ as well. AMD lists the Ryzen 5 PRO 8540U as a mobile processor, while Intel lists the Core 7 251TE as a desktop processor. The TDP values reflect this: 28 watts for AMD versus 45 watts for Intel. Both processors are currently in active production.

The release dates differ by roughly nine months. The AMD part appeared on 2024-04-15, while the Intel part arrived on 2025-01-12. The Intel processor has a launch MSRP of $384, while the database does not list a launch MSRP for the AMD part.

Specification Differences

The core counts differ by a factor of four: 24 cores for Intel versus 6 cores for AMD. Thread counts follow with 32 versus 12. Base clocks differ substantially, with AMD at 3.20 GHz and Intel at 1.40 GHz, while boost clocks favor Intel at 5.40 GHz versus 4.90 GHz for AMD.

The TDP envelope differs by 17 watts, with AMD at 28 watts and Intel at 45 watts. The process nodes differ by manufacturing generation: TSMC 4 nm for AMD versus Intel 10 nm for the Intel part. The foundry differs accordingly: TSMC for AMD, Intel for Intel.

Cache configurations differ in every level. The L1 cache is 64 KB per core for AMD versus 80 KB per core for Intel. The L2 cache is 1 MB per core for AMD versus 1.25 MB per core for Intel. The L3 cache is 16 MB shared for AMD versus 36 MB shared for Intel.

Memory support differs: AMD supports DDR5 only, while Intel supports DDR4 and DDR5. The PCIe generation and lane counts differ as well: Gen 4, 14 lanes for AMD versus Gen 5, 16 lanes for Intel. The integrated graphics differ: Radeon 740M for AMD versus UHD Graphics 770 for Intel.

The sockets differ completely: AMD Socket FP7 for the Ryzen 5 PRO 8540U versus Intel Socket 1700 for the Core 7 251TE. The market segments differ: mobile for AMD versus desktop for Intel. The die sizes differ: 137 mm² for AMD versus 215 mm² for Intel. The transistor count is listed for AMD at 20,900 million, while the database does not provide a figure for Intel.

The part numbers also differ, with AMD listing two variants (100-000001329 for FP7r2 and 100-000001331 for FP7) and Intel listing one part number (SRQAXQ5ZG). Both processors have locked multipliers, meaning neither supports unlocked overclocking through the multiplier.

Head-to-Head Benchmarks

The Intel Core 7 251TE wins every benchmark in the head-to-head comparison, a clean sweep of 17 tests. The margin varies considerably by workload type, from a near tie in single-thread tests to a 59.3 percent blowout in floating-point math.

In the Cinebench suite, the Intel part leads by roughly 39.4 percent across all six tests. The Cinebench R23 multicore score shows 25518 for Intel versus 15456 for AMD. The Cinebench R20 multicore score shows 10717 versus 6491. The Cinebench R15 multicore score shows 2572 versus 1557. The single-core variants follow the same pattern, with Intel leading by 39.5 percent in R15 and 39.4 percent in R20 and R23.

The PassMark suite reveals where the performance gap is largest and smallest. The smallest gap appears in single-thread tests, where Intel scores 3568 and AMD scores 3563, a difference of only 0.1 percent. The extended instructions test shows a modest 9.2 percent advantage for Intel, with scores of 16974 versus 15410.

The largest gaps appear in compute-heavy workloads. Floating-point math shows Intel at 85607 versus AMD at 34865, a 59.3 percent advantage. Integer math shows Intel at 125739 versus AMD at 56738, a 54.9 percent advantage. Prime number finding shows Intel at 140 versus AMD at 66, a 52.9 percent advantage. Physics simulation shows Intel at 1938 versus AMD at 983, a 49.3 percent advantage.

The data encryption test shows a 44.4 percent advantage for Intel, with scores of 22176 versus 12319. The multithread test shows a 39.3 percent advantage, with 30022 versus 18218. Data compression shows a 38.5 percent advantage, with 334399 versus 205703. Random string sorting shows a 37.4 percent advantage, with 39643 versus 24797.

The pattern is consistent: the Intel Core 7 251TE delivers higher throughput across all measured workloads, with the largest margins in math-heavy and parallel workloads. The near parity in single-thread PassMark scores suggests that both processors offer comparable per-thread performance in certain light workloads, but the Intel part pulls ahead decisively when the workload scales across its 24 cores and 32 threads. The AMD Ryzen 5 PRO 8540U remains competitive only in the narrow single-thread PassMark test, where the 5-point difference falls within measurement noise.

The benchmark data also places the Intel part in a higher performance tier overall. Its average score of 41650 sits at the 88th percentile of all CPUs, while the AMD part's 23709 sits at the 76th percentile. The nearest rivals for Intel include the Intel Core Ultra 7 265H (0.1 percent higher), the Intel Core i7-14650HX (0.2 percent higher), and the Intel Core i7-12850HX (0.3 percent lower). The nearest rivals for AMD include the Intel Core i5-11500 (exact match at 0 percent), the Intel Xeon 6333P (0.5 percent lower), and the AMD Ryzen 7 8840U (1.1 percent lower). This tier separation confirms that the Intel Core 7 251TE operates in a different performance class than the AMD Ryzen 5 PRO 8540U, regardless of the specific workload.
