AMD Ryzen 7 2700X vs AMD Ryzen 9 8945HS Comparison

Where Each One Wins

The recorded benchmark data presents a completely one-sided picture. The AMD Ryzen 9 8945HS wins all 15 head-to-head benchmark comparisons against the AMD Ryzen 7 2700X. There are no tests in the database where the older desktop processor comes out ahead. This is not a close contest with trade-offs depending on workload type; the mobile chip dominates across every measured category.

Looking at the different workload families, the 8945HS shows its largest advantages in compute-heavy and encryption-related tasks. The biggest single win is in extended instruction performance, where the 8945HS scores 26,964 versus 10,155 for the 2700X, a delta of 165.5%. Prime number finding also shows a massive gap at 124.4% ahead. These are the kinds of workloads that stress the CPU's execution engine and instruction set capabilities.

The gap narrows somewhat in memory-related tasks, though the 8945HS still maintains a commanding lead. Data compression shows a 34% advantage, random string sorting is 41.4% ahead, and data encryption comes in at 26% ahead. These are smaller margins than the compute workloads, but they still represent clear wins for the newer chip.

Single-threaded performance is another area where the 8945HS excels. In Cinebench R15 single-core, it scores 281 against 175.7, a 59.9% advantage. Geekbench single-core shows a 69.6% lead with 2116 versus 1248. PassMark single-thread performance is 59.3% higher at 3850 versus 2417. These results indicate that the architectural improvements in the newer processor benefit not just multi-threaded workloads but also lightly threaded applications.

Multi-threaded performance follows the same pattern. The 8945HS leads by 49.8% in Cinebench R15 multi-core (2640 versus 1762), by 74.3% in Geekbench multi-core (12276 versus 7045), and by 70.5% in PassMark multi-thread (29780 versus 17468). Floating-point math shows an 89.9% advantage, and integer math is 59.4% ahead. Physics simulation in PassMark is 81.1% higher at 1434 versus 792.

The database places the 8945HS at the 82nd percentile of all CPUs, while the 2700X sits at the 81st percentile. Their average benchmark scores are 31,074 versus 30,213 respectively, which puts them close in overall standing despite the individual test results showing a large per-test advantage for the newer chip.

Architecture Differences

The two processors come from different generations and target different market segments. The Ryzen 9 8945HS is a mobile processor from the 8000 series, built on Zen 4 architecture with the Hawk Point codename. It is manufactured on a 4 nm process by TSMC. The Ryzen 7 2700X is a desktop part from the 2000 series, using the Zen and Zen+ (Pinnacle Ridge) generation, built on a 12 nm process by GlobalFoundries.

The transistor counts differ substantially. The 8945HS packs 25,000 million transistors on a 178 mm² die, while the 2700X has 4,800 million transistors on a 213 mm² die. The newer chip achieves higher transistor density on a smaller physical footprint, which is consistent with the process node advantage.

Cache layouts differ between the two. The 8945HS has 64 KB of L1 cache per core, 1 MB of L2 per core, and 16 MB of shared L3. The 2700X has 96 KB of L1 per core, 512 KB of L2 per core, and 16 MB of shared L3. Both have 8 cores and 16 threads, so the L3 capacity is identical, but the distribution of lower-level cache differs.

Memory support is another clear generational split. The 8945HS supports DDR5 over a dual-channel bus with 89.6 GB/s of bandwidth. The 2700X supports DDR4 over a dual-channel bus with 46.9 GB/s. This nearly doubles the available memory bandwidth for the newer chip. Neither supports ECC memory.

PCIe connectivity also differs. The 8945HS provides Gen 4 with 20 lanes from the CPU, while the 2700X provides Gen 3 with 16 lanes. The newer chip offers a newer PCIe generation and more lanes.

Clock speeds show the 8945HS with a base clock of 4.00 GHz and boost clock of 5.20 GHz. The 2700X has a base of 3.70 GHz and boost of 4.35 GHz. The newer chip runs at higher frequencies across the range.

Power characteristics are notably different. The 8945HS has a TDP of 45 watts, while the 2700X has a TDP of 105 watts. The mobile chip delivers higher performance at less than half the power envelope. The 2700X has an unlocked multiplier; the 8945HS does not. The 8945HS includes integrated Radeon 780M graphics, while the 2700X has no integrated graphics. The 8945HS uses AMD Socket FP8, and the 2700X uses AMD Socket AM4.

Head-to-Head Benchmarks

The Cinebench R15 results establish the general pattern. In multi-core, the 8945HS scores 2640 against 1762, a 49.8% advantage. In single-core, the gap is wider at 59.9%, with 281 versus 175.7. The newer architecture improves both aspects, but the single-thread gain is proportionally larger.

Geekbench results amplify the multi-core lead. The 8945HS scores 12,276 multi-core, which is 74.3% higher than the 2700X's 7,045. Single-core is 2,116 versus 1,248, a 69.6% gap. These are substantial margins that place the mobile chip in a different performance class.

PassMark's suite breaks down into several categories. The extended instructions test shows the most dramatic difference: 26,964 versus 10,155, a 165.5% delta. Prime number finding follows at 92 versus 41, which is 124.4% ahead. Floating-point math is 61,821 versus 32,563, an 89.9% increase. Physics is 1,434 versus 792, an 81.1% gain. Multi-thread is 29,780 versus 17,468, a 70.5% advantage. Integer math is 101,226 versus 63,485, a 59.4% lead. Single-thread performance is 3,850 versus 2,417, a 59.3% gain.

Memory-oriented tasks show smaller but still decisive margins. Random string sorting is 43,202 versus 30,563, a 41.4% lead. Data compression is 356,508 versus 266,134, a 34% advantage. Data encryption is 21,323 versus 16,929, a 26% gain. These tasks rely on memory bandwidth and cache behavior, where the newer chip's DDR5 support and higher bandwidth likely contribute.

The 8945HS also outperforms the 2700X in the average benchmark comparison. Its average score is 31,074, while the 2700X averages 30,213. The nearest rivals for the 8945HS include the Intel Core i7-12700F at 31,081 (0% delta), the Intel Core 9 273PTE at 31,143 (-0.2%), and the Intel Core i7-13700TE at 31,028 (0.1%). The 2700X's nearest rivals include the AMD Ryzen 5 PRO 8640U at 30,254 (-0.1%), the AMD Ryzen 7 7736U at 30,364 (-0.5%), and the AMD Ryzen 5 7640HS at 30,390 (-0.6%).

The Verdict

The benchmark data supports a clear conclusion: the AMD Ryzen 9 8945HS outperforms the AMD Ryzen 7 2700X in every measured test. The 8945HS wins all 15 head-to-head comparisons, with margins ranging from 26% in data encryption to 165.5% in extended instructions. There is no workload category in the database where the 2700X takes the lead.

For users prioritizing single-threaded performance, the 8945HS offers a 59.3% to 69.6% advantage depending on the benchmark. This makes it the stronger choice for applications that rely on lightly threaded performance, such as everyday responsiveness and older games that scale poorly across cores.

For multi-threaded workloads, the 8945HS leads by 49.8% to 74.3% across Cinebench R15, Geekbench, and PassMark multi-thread tests. The 8-core, 16-thread configuration is preserved, but the newer architecture and higher clocks deliver substantially more throughput.

The 8945HS also offers a lower TDP of 45 watts versus 105 watts, which is relevant for system thermal design. It runs at higher clocks, supports DDR5 memory with nearly double the bandwidth, provides PCIe Gen 4 with more lanes, and includes integrated graphics. The 2700X has an unlocked multiplier, which allows manual overclocking, and uses the AM4 socket with DDR4 support.

The average benchmark scores place the 8945HS at 31,074 and the 2700X at 30,213, with percentiles of 82 and 81 respectively. The nearest rivals for each processor are different, indicating they compete in different market segments. The 8945HS sits among modern Intel and AMD mobile parts, while the 2700X is grouped with more recent mid-range mobile processors.

The choice depends on the use case. For a new system, the 8945HS provides superior performance in every measured category. The 2700X remains a functional 8-core desktop processor, but the recorded data shows no area where it matches or exceeds the 8945HS. Users on the AM4 platform with DDR4 memory might consider the 2700X for an upgrade path, but the benchmark results indicate the 8945HS is the faster processor overall.
