AMD Ryzen 7 PRO 8840HS vs Intel Core i5-14500 Comparison

The AMD Ryzen 7 PRO 8840HS and Intel Core i5-14500 represent two very different philosophies in CPU design: one is a power-efficient mobile part built on a leading-edge process, the other is a higher-power desktop chip with a hybrid core layout. The benchmark data shows a clear split in performance outcomes, with the Intel chip dominating the majority of tests, while the AMD part claims a narrow victory in one specific workload. The database records 15 head-to-head comparisons, with Intel winning 14 and AMD taking a single win, reflecting a fundamental difference in target use cases and architectural priorities.

Where Each One Wins

The Intel Core i5-14500 is the clear winner in most compute-heavy scenarios. Its hybrid architecture, combining performance and efficiency cores, gives it a significant edge in multi-threaded and floating-point workloads. The data shows Intel leads in 14 of the 15 recorded comparisons, with particularly large margins in floating-point math and prime number finding. This makes it the stronger choice for desktop productivity, content creation, and any task that scales across many threads.

The AMD Ryzen 7 PRO 8840HS only wins the Cinebench R15 multi-core test, and by a very slim margin of 0.9%. This suggests that in older or more lightly threaded rendering workloads, the AMD chip can hang with the Intel part, but it does not translate into broader multi-core dominance. The AMD processor is better positioned as a mobile solution, given its 28W TDP and integration into laptops, where its efficiency and the Radeon 780M integrated graphics matter more than raw multi-threaded output.

In single-threaded performance, the Intel chip also comes out ahead in every recorded test, including a 10.1% lead in Cinebench R23 single-core. This indicates that for everyday responsiveness and applications that rely on single-core speed, such as legacy software or lightly threaded games, the Intel part is the better performer. The AMD chip, however, offers a more balanced package for portable devices, where the combination of CPU and GPU efficiency is critical.

Architecture Differences

The two processors are built on fundamentally different architectures. The AMD Ryzen 7 PRO 8840HS uses the Zen 4 architecture, codenamed Hawk Point, manufactured on a 4nm process at TSMC. This is a monolithic design with 8 cores and 16 threads, all based on the same Zen 4 core. The chip has a base clock of 3.30 GHz and a boost clock of 5.10 GHz, with a TDP of 28W, which is typical for a mobile processor. The cache hierarchy includes 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3 cache. The transistor count is listed at 25,000 million, with a die size of 178 mm².

The Intel Core i5-14500 uses the Raptor Lake architecture, specifically Raptor Lake-R, and is manufactured on a 10nm process at Intel. It is a hybrid design with 14 cores and 20 threads, combining performance cores and efficiency cores in a single package. The base clock is 2.60 GHz, and the boost clock is 5.00 GHz, with a TDP of 65W. The cache layout is different: 80 KB of L1 per core, 1.25 MB of L2 per core, and 24 MB of shared L3 cache. The die size is 215 mm², which is larger than the AMD chip, reflecting the different process node and core count.

The memory support also differs. The AMD chip supports only DDR5 memory with a dual-channel bus and a memory bandwidth of 89.6 GB/s. The Intel chip supports both DDR4 and DDR5 memory, also with a dual-channel bus, but no memory bandwidth figure is recorded in the database. Both processors support ECC memory, which is notable for workstation use. The PCIe support is another point of difference: the AMD chip offers Gen 4 with 20 lanes (CPU only), while the Intel chip offers Gen 5 with 16 lanes (CPU only), giving Intel a potential advantage in bandwidth for newer GPUs and storage devices.

Head-to-Head Benchmarks

The largest margin in the entire comparison is in PassMark floating-point math, where the Intel Core i5-14500 scores 79,576 versus 55,739 for the AMD chip, a delta of 30%. This is a massive lead and indicates that the Intel architecture is significantly better at handling complex mathematical operations, which is crucial for scientific computing, financial modeling, and 3D rendering. Similarly, in PassMark find prime numbers, Intel leads by 20.8%, scoring 106 versus 84, which further confirms its superiority in integer-heavy workloads.

In multi-threaded tests, the Intel chip maintains a solid advantage. In PassMark multi-thread, Intel scores 30,777 versus 26,646 for AMD, a 13.4% lead. In Cinebench R23 multi-core, Intel scores 15,012 versus 14,784, a 1.5% lead, which is a much smaller margin than the PassMark test suggests. This indicates that the two chips are closer in some rendering workloads than in others, likely due to differences in how the benchmarks utilize the core configurations. The Intel chip also leads in PassMark integer math by 13.7% (108,124 versus 93,342) and in data compression by 16.2% (371,294 versus 311,199).

Single-threaded performance is where the Intel chip has a more pronounced advantage. In Cinebench R23 single-core, Intel scores 1,917 versus 1,724 for AMD, a 10.1% lead. In PassMark single-thread, Intel scores 3,952 versus 3,692, a 6.6% lead. These results show that the Intel core design, with its higher boost clock and hybrid architecture, is more efficient in single-threaded execution despite having a lower base clock. The only AMD win comes in Cinebench R15 multi-core, where AMD scores 2,458 versus 2,435, a 0.9% lead, which is within the margin of error for most practical purposes.

Specification Differences

The two processors differ in several key specifications that are recorded in the database. The AMD Ryzen 7 PRO 8840HS has 8 cores and 16 threads, while the Intel Core i5-14500 has 14 cores and 20 threads. The base clock is higher on the AMD chip at 3.30 GHz versus 2.60 GHz, but the boost clock is slightly higher on the Intel chip at 5.00 GHz versus 5.10 GHz, meaning the AMD chip actually boosts slightly higher. The TDP is a major difference: the AMD chip is rated at 28W, while the Intel chip is rated at 65W, making the AMD part far more power-efficient for mobile use.

The process node is another clear split: AMD uses 4nm TSMC, while Intel uses 10nm. The cache configuration differs in size and allocation, with the Intel chip offering more L1 (80 KB per core versus 64 KB per core), more L2 (1.25 MB per core versus 1 MB per core), and more L3 (24 MB shared versus 16 MB shared). Memory support is a point of flexibility for Intel, which supports both DDR4 and DDR5, while AMD only supports DDR5. The PCIe generation is also different: Intel offers Gen 5 with 16 lanes, while AMD offers Gen 4 with 20 lanes, trading off raw bandwidth for more lanes. The integrated graphics differ as well: AMD has the Radeon 780M, while Intel has the UHD Graphics 770.
