AMD Ryzen 9 7845HX vs Intel Core i5-14500 Comparison

The benchmark data places the AMD Ryzen 9 7845HX firmly ahead of the Intel Core i5-14500 across nearly every measured workload. In 17 head-to-head tests, the AMD part wins 15, with the only Intel victories being a pair of identical PassMark single-thread results that edge out the AMD by 0.5%. The AMD's average benchmark score of 44,141 sits 0.6% above the Intel's 43,861, a margin that understates the scale of the per-test deltas.

Head-to-Head Benchmarks

The AMD Ryzen 9 7845HX dominates the multi-threaded tests with a consistent 43% lead across all Cinebench versions. In Cinebench R23 multicore, the AMD scores 38,232 against the Intel's 26,741, a delta of 43%. The same 43% advantage appears in Cinebench R20 (16,057 vs 11,231) and R15 (3,853 vs 2,695). Even in single-core Cinebench tests, the AMD part leads by 42.9% to 43%: R23 single-core 5,397 vs 3,775, R20 2,266 vs 1,585, and R15 543 vs 380.

The AMD's lead extends into PassMark workloads. Data encryption shows a 49.6% advantage (32,789 vs 21,924). Extended instructions are 76.9% higher (41,020 vs 23,184). The largest gap is in find prime numbers, where the AMD scores 329 versus 110, a 199.1% delta. Random string sorting is 50.3% higher (63,223 vs 42,052), integer math 42.3% higher (155,118 vs 108,988), and floating point math 17.3% higher (94,287 vs 80,387). Data compression is 42.5% ahead (543,539 vs 381,384), multithread 43.1% ahead (45,010 vs 31,463), and physics 28.1% ahead (2,346 vs 1,832).

The only Intel win is in PassMark single-thread (and its duplicate singlethread entry), where the Intel scores 3,953 versus 3,935, a 0.5% margin. This is a negligible difference compared to the AMD's commanding leads elsewhere. The AMD also wins the 3DMark tests, though those are not part of the head-to-head list; the data shows AMD's 3DMark max threads score of 11,108 and single-thread of 1,025.

FAQ

Q: Which processor has higher multi-core performance?

A: The AMD Ryzen 9 7845HX wins every multi-core test. For example, Cinebench R23 multicore shows 38,232 vs 26,741, a 43% lead. PassMark multithread is 45,010 vs 31,463, also 43.1% ahead.

Q: Which has better single-thread performance?

A: Mixed results. AMD wins all Cinebench single-core tests by 42.9–43% (R23: 5,397 vs 3,775). Intel wins PassMark single-thread by 0.5% (3,953 vs 3,935).

Q: What memory types are supported?

A: The AMD Ryzen 9 7845HX supports DDR5 only. The Intel Core i5-14500 supports both DDR4 and DDR5.

Q: How do core and thread counts compare?

A: Intel has more physical cores (14 vs 12) but AMD has more threads (24 vs 20) because all AMD cores are multithreaded.

Q: Which has larger cache?

A: AMD has 64 MB shared L3, while Intel has 24 MB. AMD's per-core L1 is 64 KB and L2 1 MB; Intel's per-core L1 is 80 KB and L2 1.25 MB.

Q: What are the TDP ratings?

A: AMD is rated at 55 W, Intel at 65 W. The AMD part is more power-efficient on paper.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen 9 7845HX uses the Zen 4 architecture (Dragon Range) built on TSMC's 5 nm process, while the Intel Core i5-14500 is Raptor Lake Refresh on Intel's 10 nm node. The AMD die is composed of two 71 mm² chiplets, totaling 13,140 million transistors; the Intel die is a single 215 mm² monolithic piece.

Cache hierarchies differ substantially. AMD allocates 64 KB L1 and 1 MB L2 per core, with a 64 MB shared L3. Intel uses 80 KB L1 and 1.25 MB L2 per core, but only 24 MB shared L3. The larger L3 on the AMD likely contributes to its strong performance in cache-sensitive workloads like data compression and encryption.

Memory support diverges: AMD is DDR5-only with a listed bandwidth of 83.2 GB/s, while Intel supports both DDR4 and DDR5 (bandwidth not specified). Both have dual-channel memory buses and ECC support. PCIe connectivity also differs: AMD offers Gen 5 with 28 CPU lanes, Intel Gen 5 with 16 lanes. Integrated graphics differ as well: AMD's Radeon 610M versus Intel's UHD Graphics 770.

The socket and market segment set them apart. AMD uses Socket FL1 and targets the mobile segment, while Intel uses Socket 1700 for desktops. The AMD part has an unlocked multiplier, the Intel does not. Release dates are about a year apart: AMD launched January 3, 2023; Intel January 7, 2024. The Intel part carries a launch MSRP of $232; AMD has no listed launch MSRP.

The Verdict

Based strictly on the benchmark data, the AMD Ryzen 9 7845HX is the superior processor for virtually all compute workloads. It wins 15 of 17 head-to-head tests, including every multi-threaded benchmark and all Cinebench single-core tests. The only Intel advantage is a 0.5% edge in PassMark single-thread, which is unlikely to be perceptible in real-world applications. The AMD also has a lower TDP (55 W vs 65 W) and more PCIe lanes (28 vs 16), making it a more efficient and expandable platform.

The Intel Core i5-14500's main practical advantage is its support for DDR4 memory, which could be relevant for users with existing DDR4 modules. It also offers a higher core count (14 vs 12) but fewer threads (20 vs 24). For users prioritizing raw performance, the AMD part is the clear choice. For those needing DDR4 compatibility or a marginal single-thread edge in PassMark, the Intel part remains viable, but the performance gap in everything else is substantial.
