Architecture Differences

The AMD Ryzen 5 PRO 8640HS uses the Zen 4 architecture under the Hawk Point codename, part of the 8000 series. It has 6 cores and 12 threads, meaning it supports simultaneous multithreading. The chip is manufactured on a 4 nm process by TSMC and contains 25,000 million transistors on a 178 mm² die. The Intel Core 7 350, with the Wildcat Lake codename, also has 6 cores but only 6 threads, indicating no hyperthreading. It is built on a 3 nm process by Intel.

Cache layouts differ substantially. The AMD chip provides 64 KB of L1 cache per core, 1 MB of L2 per core, and 16 MB of shared L3 cache. The Intel chip provides 192 KB of L1 per core, 2.5 MB of L2 per core, but only 6 MB of shared L3 cache. The larger L3 pool on the AMD side likely explains part of its multi-threaded advantage in workloads that repeatedly access shared data.

Memory architecture also separates these two. The AMD part uses a dual-channel DDR5 interface with 89.6 GB/s of bandwidth, while the Intel part uses a single-channel interface with 59.7 GB/s of bandwidth. The AMD chip also supports ECC memory, which the Intel chip does not. PCIe connectivity differs: AMD offers Gen 4 with 20 lanes from the CPU, while Intel offers Gen 4 with only 6 lanes.

The integrated graphics represent another divergence. AMD uses the Radeon 760M, while Intel uses Xe3 Graphics with 2 Xe cores. Both chips are unlocked multipliers, so neither supports overclocking. The AMD part uses AMD Socket FP7, and the Intel part uses Intel BGA 1516.

Where Each One Wins

The AMD Ryzen 5 PRO 8640HS wins in every Cinebench multi-core test, every PassMark math test except prime numbers, and all data-oriented workloads. Its largest victory comes in Cinebench R23 multi-core, where it scores 18104 versus 8030, a 125.5% advantage. It also leads PassMark integer math by 107%, scoring 69839 against 33734. PassMark random string sorting shows a 75.4% lead, with 30235 against 17238. Data compression favors AMD by 72.2%, with 246446 against 143123. Extended instructions show a 53.6% lead, and data encryption shows a 36.9% lead.

The Intel Core 7 350 wins in single-threaded tests and a few specialized workloads. The PassMark single-thread score of 4100 beats the AMD score of 3561 by 13.1%. Cinebench R15 single-core also goes to Intel, 292 to 257, a 12% difference. PassMark physics favors Intel, 1173 to 1043, an 11.1% edge. The largest Intel win is PassMark find prime numbers, where it scores 107 against 71, a 33.6% advantage.

The pattern is clear: AMD wins heavily in multi-threaded, data-heavy, and integer workloads, while Intel wins in single-thread responsiveness and specific algorithmic tasks like prime number generation. The floating-point math test is nearly a tie, with AMD at 43019 and Intel at 42809, a 0.5% difference.

The two processors differ in several key specifications. The AMD Ryzen 5 PRO 8640HS has a base clock of 3.50 GHz and a boost clock of 4.90 GHz. The Intel Core 7 350 has a base clock of 1.50 GHz and a boost clock of 4.80 GHz. The AMD chip has a thermal design power of 28 watts, while the Intel chip is rated at 15 watts.

Thread counts differ: AMD provides 12 threads from 6 cores, while Intel provides 6 threads from 6 cores. The process nodes differ, with AMD on 4 nm and Intel on 3 nm. Total L3 cache differs: AMD has 16 MB shared, Intel has 6 MB shared. L1 and L2 per core also differ, with Intel offering larger per-core caches at 192 KB L1 and 2.5 MB L2, versus 64 KB L1 and 1 MB L2 for AMD.

Memory support differs in both type and channel configuration. AMD supports DDR5 dual-channel with 89.6 GB/s bandwidth. Intel supports DDR5 and LPDDR5X single-channel with 59.7 GB/s bandwidth. ECC support is present only on AMD. PCIe lanes differ: AMD has 20 Gen 4 lanes, Intel has 6 Gen 4 lanes.

The AMD chip has no recorded launch MSRP in the database.

Head-to-Head Benchmarks

The Cinebench R23 multi-core result is the single largest gap between these two processors. AMD scores 18104, Intel scores 8030, and the difference is 125.5%. This result indicates that the AMD chip can handle heavily threaded rendering workloads at more than double the speed of the Intel chip.

PassMark integer math is another massive win for AMD. The score of 69839 versus 33734 represents a 107% advantage. This test measures general integer processing throughput, and the difference suggests that the AMD chip's 12 threads provide a clear benefit in parallel integer operations.

PassMark random string sorting shows AMD at 30235 and Intel at 17238, a 75.4% lead. Data compression shows a similar pattern, with AMD at 246446 and Intel at 143123, a 72.2% lead. These results point to AMD handling memory-intensive data manipulation tasks more efficiently.

The Cinebench R20 tests show a different picture across single and multi-core. In multi-core, AMD leads 7603 to 5373, a 41.5% advantage. In single-core, AMD leads 1073 to 758, a 41.6% advantage. This is notable because the Intel chip wins the Cinebench R15 single-core test, but the R20 single-core test goes to AMD. The database shows a 12% Intel win in R15 single-core, but a 41.6% AMD win in R20 single-core.

The Intel wins are concentrated in specific areas. PassMark find prime numbers favors Intel by 33.6%, with 107 against 71. PassMark single-thread favors Intel by 13.1%, with 4100 against 3561. PassMark physics favors Intel by 11.1%, with 1173 against 1043. Cinebench R15 single-core favors Intel by 12%, with 292 against 257.

The Cinebench R15 multi-core test shows AMD at 1824 and Intel at 1220, a 49.5% lead for AMD. PassMark multithread shows AMD at 21465 and Intel at 15170, a 41.5% lead. PassMark data encryption shows AMD at 14962 and Intel at 10933, a 36.9% lead. PassMark extended instructions shows AMD at 18507 and Intel at 12045, a 53.6% lead.

The floating-point math test is the closest result in the entire comparison. AMD scores 43019, Intel scores 42809, and the difference is only 0.5%. This near-tie suggests that for pure floating-point throughput, the two chips are effectively equivalent, despite the large differences in other math tests.

The Verdict

The data points to a straightforward conclusion for users who prioritize multi-threaded performance: the AMD Ryzen 5 PRO 8640HS is the stronger processor. It wins 12 of 17 head-to-head benchmarks, including every Cinebench multi-core test and every PassMark data-heavy test. Its average benchmark score of 28478 is roughly 60% higher than the Intel average of 17779, and it sits in the 80th percentile of all CPUs versus the 71st percentile for Intel.

The Intel Core 7 350 has a narrow band of advantages. It wins single-thread tests in PassMark and Cinebench R15, and it wins physics and prime number generation. These wins are real but small in magnitude compared to the AMD multi-core victories. The largest Intel win is 33.6% in prime numbers, while the largest AMD win is 125.5% in Cinebench R23 multi-core.

For workloads like rendering, data compression, encryption, integer math, and random string sorting, the AMD chip delivers between 36.9% and 125.5% higher performance. For workloads that depend on single-thread responsiveness and specific algorithmic patterns, the Intel chip offers a smaller but measurable edge.

The Intel part does have a lower thermal design power of 15 watts versus 28 watts for AMD, and it uses a newer 3 nm process node. It also supports LPDDR5X memory, which the AMD chip does not. But the recorded benchmark data shows that these advantages do not translate into higher scores in most tests. The AMD chip, despite a higher TDP and an older process node, delivers substantially higher performance across the majority of the measured workloads.

The near-tie in floating-point math, at 0.5%, indicates that neither chip has a universal advantage in all math operations. The AMD chip wins integer math by 107%, but the prime number test goes to Intel by 33.6%. This split suggests that the choice between these two processors depends heavily on the specific workload, but for the broad categories of multi-threaded and data-intensive tasks, the AMD Ryzen 5 PRO 8640HS is the clear winner in the recorded data.
