The Verdict

The benchmark data splits this comparison into two clear profiles. The Intel Core 7 253PQE is the stronger choice for workloads that favor high single-core performance and floating-point math. Its Cinebench R23 single-core score of 4,431 more than doubles the AMD's 1,857, and it leads by 58.1% in that test. It also wins in PassMark floating-point math by 17.6% and in PassMark physics by 26.4%. For rendering and multi-core tasks measured by Cinebench R23, the Intel leads by 19.5% with a score of 31,390 versus 25,265.

The AMD Ryzen 7 8840HX wins the majority of the head-to-head benchmark comparisons, taking 7 wins out of 13 recorded tests. Its advantages show up in integer math, data encryption, extended instructions, prime number finding, data compression, random string sorting, and multithread performance. The AMD's multithread win is narrow at 0.2%, but its encryption lead is substantial at 17.3% and its prime number lead is 47.6%. The AMD also holds the higher percentile ranking at 94 versus 91 for the Intel.

Pick the Intel Core 7 253PQE for single-thread-heavy applications, physics simulations, and workloads that use floating-point math. Pick the AMD Ryzen 7 8840HX for encryption, integer math, data compression, and general multithreaded tasks where it wins more individual benchmarks. The Intel is a desktop part with a 125 W TDP and a launch MSRP of $409, while the AMD is a mobile part with a 55 W TDP. The data shows two different design targets: the Intel pushes clock speed and floating-point throughput, while the AMD balances a higher core count with stronger integer and encryption performance.

Head-to-Head Benchmarks

The largest single-core gap appears in Cinebench R23 single-core, where the Intel Core 7 253PQE scores 4,431 against the AMD's 1,857, a 58.1% difference. That is the dominant margin in this comparison. The PassMark single-thread test shows a smaller but still clear Intel lead of 9.8% at 4,389 versus 3,958. In Cinebench R23 multi-core, the Intel leads by 19.5% with 31,390 against 25,265, confirming that the Intel's advantage is not limited to single-threaded work.

The AMD's biggest win is in PassMark find prime numbers, where it scores 304 against 206, a 47.6% margin. Data encryption also favors the AMD heavily at 29,919 versus 25,515, a 17.3% lead. Extended instructions go to the AMD by 12.8% with 36,527 against 32,390. Integer math shows the AMD ahead by 6.3% at 146,506 versus 137,795. Random string sorting favors the AMD by 6.9% at 57,971 versus 54,222. Data compression is close, with the AMD at 496,427 against 487,335, a 1.9% edge. The multithread test is the tightest result: the AMD scores 41,732 versus 41,656, a 0.2% margin.

The Intel wins in floating-point math by 17.6% with 105,279 against 86,747, and in physics by 26.4% with 2,970 against 2,185. These wins, combined with the Cinebench results, show the Intel's strength in numerically intensive workloads. The AMD's wins cluster around integer operations, encryption, and data handling. The 7-6 win split in favor of the AMD reflects a broader but shallower set of advantages, while the Intel's wins are often larger in magnitude.

Specification Differences

The core and thread counts differ: the AMD Ryzen 7 8840HX uses 12 cores and 24 threads, while the Intel Core 7 253PQE uses 10 cores and 20 threads. Clock speeds favor the Intel, which has a base clock of 3.50 GHz and a boost clock of 5.70 GHz, compared to the AMD's 2.90 GHz base and 5.10 GHz boost. The TDP gap is significant: the Intel is rated at 125 W, while the AMD is rated at 55 W.

The sockets are different as well. The AMD uses AMD Socket FL1, and the Intel uses Intel Socket 1700. The AMD is a mobile segment part, while the Intel is a desktop segment part. The AMD has an unlocked multiplier, while the Intel does not. Memory support differs: the AMD supports DDR5 only, while the Intel supports both DDR4 and DDR5. Memory bandwidth is slightly higher on the Intel at 89.6 GB/s versus 83.2 GB/s. ECC memory support is present on the Intel but absent on the AMD.

PCIe configurations also differ. The AMD provides Gen 5 with 28 lanes (CPU only), while the Intel provides Gen 5 with 16 lanes (CPU only). Integrated graphics differ as well: the AMD uses Radeon 610M, and the Intel uses UHD Graphics 770. The release dates are different, with the AMD released earlier and the Intel later. The Intel has a launch MSRP of $409; the AMD has no recorded launch MSRP.

Architecture Differences

The AMD Ryzen 7 8840HX is built on Zen 4 architecture with the codename Dragon Range. It uses a 5 nm process from TSMC and integrates 13,140 million transistors across a die size of 2x 71 mm². The AMD's cache layout includes 64 KB of L1 per core, 1 MB of L2 per core, and 64 MB of shared L3 cache.

The Intel Core 7 253PQE uses the Bartlett Lake codename and is built on a 10 nm process at Intel. Its cache layout differs: 80 KB of L1 per core, 2 MB of L2 per core, and 33 MB of shared L3 cache. The Intel's L2 cache per core is double the AMD's, while the AMD's shared L3 cache is nearly double the Intel's. The Intel has no recorded transistor count or die size in the database.

The manufacturing approaches are distinct: TSMC at 5 nm for the AMD versus Intel at 10 nm for the Intel. The AMD's smaller process node likely contributes to its lower 55 W TDP despite having more cores. The Intel's larger process node and higher clocks lead to its 125 W TDP. The AMD's Zen 4 generation label is listed as Ryzen 7 (Zen 4, Dragon Range), while the Intel's generation label is Core 7 (Bartlett Lake) with no architecture field recorded.

Where Each One Wins

The Intel Core 7 253PQE wins in scenarios where floating-point math and physics calculations dominate. Its 17.6% lead in PassMark floating-point math and 26.4% lead in PassMark physics make it the stronger choice for simulation workloads and numerically intensive applications. The Cinebench R23 results reinforce this: the Intel leads by 19.5% in multi-core and by 58.1% in single-core, which suggests it handles both lightly threaded and heavily threaded render tasks better. The PassMark single-thread score of 4,389 versus 3,958 adds another data point for applications that rely on one or two fast cores. The Intel also offers ECC memory support, a desktop socket, DDR4 and DDR5 compatibility, and a higher memory bandwidth of 89.6 GB/s.

The AMD Ryzen 7 8840HX wins in data-centric workloads. It leads in data encryption by 17.3%, extended instructions by 12.8%, integer math by 6.3%, random string sorting by 6.9%, and find prime numbers by 47.6%. The data compression win is narrow at 1.9%, and the multithread win is a 0.2% margin. These results indicate the AMD handles encryption, integer arithmetic, and data transformation tasks with more efficiency. Its 12-core, 24-thread configuration with 64 MB of shared L3 cache supports this profile. The AMD also has a much lower TDP at 55 W versus 125 W, and it provides more PCIe lanes at 28 versus 16. Its 94th percentile ranking versus the Intel's 91st indicates a higher standing among all CPUs in the database.

The use-case split is clean. For floating-point, physics, and Cinebench-style rendering, the Intel is the better performer. For encryption, integer math, and data compression, the AMD holds the edge. The Intel wins fewer tests but by larger margins; the AMD wins more tests but often by smaller amounts. The average benchmark score tells a different story: the AMD averages 71,797, while the Intel averages 55,919. That gap places the AMD in a higher overall performance tier despite losing the Cinebench tests. The nearest rival data confirms this: the AMD's closest rival is the Intel Core Ultra 7 265KF at a 0.2% delta, while the Intel's closest rival is the Intel Core i9-14900HX at a 0.2% delta.
