AMD Ryzen 7 PRO 8840U vs Intel Core i7-13705H Comparison

Head-to-Head Benchmarks

The benchmark data tells a surprisingly one-sided story in the Cinebench suite, where the AMD Ryzen 7 PRO 8840U dominates the Intel Core i7-13705H by a consistent margin. Across Cinebench R15, R20, and R23, the AMD chip wins both single-core and multi-core tests by roughly 26.6% each time. For example, in Cinebench R23 multi-core the 8840U scores 20,254 versus 15,998 for the Intel part, and in single-core it posts 2,859 against 2,258. The R15 results mirror this: 2,041 versus 1,612 in multi-core and 288 versus 227 in single-core. This uniformity suggests the AMD architecture simply extracts more performance per clock in rendering workloads.

The Passmark suite paints a more mixed picture, however. The AMD chip wins 12 of the 17 total head-to-head tests, but the Intel part takes the remaining five, and some of those wins are substantial. Most notably, the i7-13705H crushes the 8840U in Passmark Physics, scoring 1,854 versus 1,174 — a 36.7% advantage. It also leads in floating-point math (63,064 versus 50,746, a 19.5% gap) and in find-prime-numbers (116 versus 76, a 34.5% margin). The Intel chip narrowly edges out AMD in data compression (273,720 versus 272,664, just 0.4%) and in Passmark multithread (24,460 versus 23,850, a 2.5% lead).

AMD’s wins in the remaining tests range from modest to decisive. The 8840U takes extended instructions by 21% (19,132 versus 15,810), random string sorting by 13.1% (33,109 versus 29,285), and single-thread performance by 4.5% (3,641 versus 3,483). It also wins integer math by 2.8% (88,339 versus 85,927) and data encryption by 0.7% (16,441 versus 16,324). The overall average benchmark scores are nearly identical — 32,233 for AMD versus 32,076 for Intel — which places both chips in the same performance tier, with the 8840U at the 83rd percentile and the i7-13705H at the 82nd.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen 7 PRO 8840U uses Zen 4 architecture on TSMC’s 4 nm process, with a die size of 178 mm² and 25,000 million transistors. It has 8 cores and 16 threads, with a base clock of 3.30 GHz and a boost clock of 5.10 GHz. Its cache layout includes 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3. The chip is built for AMD Socket FP7 and carries a 28 W TDP.

The Intel Core i7-13705H, by contrast, uses Raptor Lake architecture on Intel’s 10 nm process, with a larger 257 mm² die. It packs 14 cores and 20 threads — a hybrid design that mixes performance and efficiency cores — with a base clock of 2.40 GHz and a boost clock of 5.00 GHz. Its cache is larger per core: 80 KB of L1, 2 MB of L2 per core, and 24 MB of shared L3. The Intel part has a 45 W TDP and uses Intel BGA 1744.

Memory support also diverges. The AMD chip supports DDR5 only, with dual-channel memory and 89.6 GB/s of bandwidth, plus ECC memory support. The Intel chip supports both DDR4 and DDR5 in dual-channel mode, but its memory bandwidth is not listed, and it lacks ECC support. PCIe connectivity differs as well: AMD provides Gen 4 with 20 CPU lanes, while Intel offers Gen 5 with only 8 CPU lanes. Integrated graphics are another differentiator — the 8840U uses Radeon 780M, while the i7-13705H uses Iris Xe Graphics 96EU.

Where Each One Wins

The data suggests a clear split based on workload type. The AMD Ryzen 7 PRO 8840U is the pick for rendering, content creation, and any heavily threaded compute that relies on sustained multi-core throughput. Its Cinebench scores are uniformly about 26.6% higher than the Intel part across every version of that benchmark, which translates to faster video exports, 3D renders, and batch image processing. The AMD chip also wins in extended instruction workloads (21% ahead), random string sorting (13.1%), integer math (2.8%), and single-thread tasks (4.5%), making it the better all-rounder for mixed productivity.

The Intel Core i7-13705H has its own niche, however. Its Passmark Physics score of 1,854 versus 1,174 is a massive 36.7% lead, which indicates a clear advantage in simulation and physics-based compute — think engineering simulations, scientific computing, or any workload that stresses floating-point vector operations. The Intel chip also wins floating-point math by 19.5% and find-prime-numbers by 34.5%, pointing to strong raw FPU throughput. For users running physics-heavy applications or number-crunching that leans on FP performance, the Intel part is the better choice despite losing the Cinebench suite.

The two chips are nearly tied in data encryption (AMD leads by 0.7%) and data compression (Intel leads by 0.4%), so those workloads are effectively a wash. The overall multithread Passmark score slightly favors Intel (by 2.5%), but that single metric is outweighed by AMD’s dominance across the broader benchmark set.

The Verdict

The benchmark results make the choice clear for most users. The AMD Ryzen 7 PRO 8840U wins 12 of 17 head-to-head tests, including every Cinebench benchmark by a uniform 26.6% margin. It also holds advantages in single-thread performance (4.5% in Passmark), extended instructions (21%), integer math (2.8%), random string sorting (13.1%), and data encryption (0.7%). Its 28 W TDP versus Intel’s 45 W suggests substantially better efficiency for mobile workloads, and it adds ECC memory support. If you are rendering video, compiling code, or doing general productivity work, the data points squarely at the AMD part.

The Intel Core i7-13705H is the pick only if your workload specifically leans on physics simulation or floating-point-heavy math. Its 36.7% lead in Passmark Physics and 19.5% lead in floating-point math are real advantages, and its 14 cores and 20 threads give it raw thread-count bragging rights. But those wins come with a higher TDP and a loss in nearly every other benchmark category. The overall average scores are close — 32,233 versus 32,076 — but the distribution of wins heavily favors AMD. For a balanced mobile processor that wins rendering and general compute while using less power, the Ryzen 7 PRO 8840U is the data-backed choice.
